Telemedicine models of care: A retrospective review of telehealth in a Melbourne outpatient chronic wound service in 2021

Abstract

To review the application of telehealth guidelines developed by Bondini et al for clinicians to determine patient suitability for telehealth in an outpatient Chronic Wound Service, including the proportion of patients suitable for telehealth, type and mode of telehealth encounters. Retrospective, random convenience sample of patients attending the Chronic Wound Service in 2021. Fifty-six patients were included, most with leg/foot wounds (93%), median age 74 [54–84], 64% male. Four patients at admission and 19 patients at review met criteria for telehealth. Six percent of encounters were telehealth; phone-only (82%), unscheduled nursing reviews (77%) in patients with healing wounds. Thirty patients (54%) received at least one telehealth encounter. Telehealth occurred 35.6 days later in the admission than face-to-face encounters (p < 0.05, 95% CI 14.9–56.3). There was a significant relationship between patients receiving telehealth and meeting telehealth suitability criteria on reviews (X 2 (1) = 19.6*, p < 0.001). Eighteen percent of patients required wound-related hospitalisation during their outpatient admission. Telehealth guidelines identified patients suitable for telehealth, although the proportion of patients was small. Telehealth was mostly utilised for nurse-led telephone calls in patients with improving wounds. Future research into use of telephone review for clinical standards of wound care is warranted.

Effects of exercise in treating patients with venous leg ulcers: An umbrella review

Abstract

Venous leg ulcers (VLUs) represent a substantial challenge within the healthcare landscape, thereby necessitating efficacious therapeutic strategies. Exercise has been investigated as a prospective intervention to bolster the management of VLUs. The objective of this comprehensive review is to systematically scrutinize and appraise the extant body of evidence pertaining to the impact of exercise on the treatment of patients diagnosed with VLUs. A comprehensive literature search was executed across multiple databases, encompassing PubMed, the Cochrane Library, Web of Science, Embase, and Google Scholar. The methodological rigour was evaluated utilizing the Assessment of Multiple Systematic Reviews 2 (AMSTAR-2) instrument, while the quality of the evidence was appraised via the Grading of Recommendations Assessment, Development and Evaluation (GRADE) classification system. The relative efficacy of exercise interventions on outcomes related to VLUs, including rates of wound healing, total range of motion in the ankle joint, and adherence rates, was synthesized. Data were consolidated employing fixed-effects models, and the impact of exercise on these outcomes was visually represented through the use of forest plots. The methodological foundation of this investigation comprised four systematic reviews and meta-analyses, each characterized by an intermediate level of methodological rigour and evidence quality. Subsequent analyses revealed that exercise interventions exert a multifaceted and favourable impact on the therapeutic landscape of VLUs. These interventions distinctly contribute to the enhancement of wound healing rates (risk difference 0.17, 95% confidence interval [CI]: 0.06–0.28) and the extension of ankle range of motion (mean difference [MD] 6.10, 95% CI: 4.61–7.59). Furthermore, Pooled adherence rate was 0.70 (95% CI: 0.20–2.45) with no significant heterogeneity. In conclusion, although existing evidence supports the positive impact of exercise training on VLUs, higher-quality research is still needed to deepen our understanding of its effects and provide more specific guidance for clinical practice.

Comparing the Waterlow and Jackson/Cubbin pressure injury risk scales in intensive care units: A multi‐centre study

Abstract

To compare the predictive properties of the Jackson/Cubbin scale and Waterlow scales in intensive care unit patients. A multi-centre study. This study was conducted between April 2021 and February 2023 in 72 intensive care units of 38 tertiary hospitals in Gansu Province, China. All adults admitted to the intensive care unit for 24 hours or more without pressure injury on admission were screened using the Waterlow scale and Jackson/Cubbin scales in intensive care. Additionally, the negative predictive value, positive predictive value, sensitivity, specificity and receiver operating characteristic curve with area under the curve of the Waterlow scale and Cubbin/Jackson scales were determined. The participant population for this study included 6203 patients. Predictive properties for the Jackson/Cubbin scales and Waterlow scales, respectively, were as follows: Cut-off scores, 28 versus 22; AUC, 0.859 versus 0.64; sensitivity, 92.4% versus 51.9%; specificity, 67.26% versus 71.46%; positive predictive value, 35% versus 23%; negative predictive value, 99.9% versus 99.1%. Both Waterlow scales and Jackson/Cubbin scales could predict pressure injury risk for patients in the intensive care unit. However, the Jackson/Cubbin scale demonstrated superior predictive properties than the Waterlow scale.

Risk factors related to surgical wound infection after caesarean section: A systematic review and meta‐analysis

Abstract

Surgical site infection (SSI) is one of the common postoperative complications after caesarean section for pregnant women. Previous studies have investigated the risk factors for SSI in pregnant women undergoing caesarean delivery. Whereas big differences in research results exist, and the correlation coefficients of different research results are quite different. A meta-analysis was conducted to examine the risk factors related to SSI in pregnant women undergoing caesarean delivery. We searched English databases to collect case–control studies or cohort studies published between 1 January 2015 and 15 November 2023, including PubMed, Web of Science and ScienceDirect. The risk of bias of the included studies was assessed via Newcastle-Ottawa Scale. The analysis was performed using RevMan 5.4.1 tool. A total of 24 articles (n = 581, 895) were selected in this meta-analysis. The following risk factors were presented to be significantly correlated with SSI in pregnant women following caesarean delivery: smoking (odds ratio [OR] = 1.64, 95% confidence interval [CI] [1.31, 2.04]), previous caesarean section (OR = 1.46, 95% CI [1.18, 1.82]), multiple vaginal examinations (OR = 2.92, 95% CI [1.91, 4.46]), membrane rupture (OR = 1.68, 95% CI [1.19, 2.38]), hypertensive disorders (OR = 1.85, 95% CI [1.33, 2.57]), diabetes mellitus (OR = 1.36, 95% CI [1.18, 1.57]), high body mass index (OR = 1.57, 95% CI [1.35, 1.84]). Occurrence of SSI is influenced by a variety of factors. Thus, we should pay close attention to high-risk subjects and take crucial targeted interventions to lower the SSI risk after caesarean section. Owing to the limited quality and quantity of the included studies, more rigorous studies with adequate sample sizes are needed to verify the conclusion.

Unveiling the intellectual structure of informality: Insights from the socioeconomic literature

by Nelson Alfonso Gómez-Cruz, David Anzola, Aglaya Batz Liñeiro

In the socioeconomic sphere, the concept of informality has been used to address issues pertaining to economic dynamics, institutions, work, poverty, settlements, the use of space, development, and sustainability, among others. This thematic range has given way to multiple discourses, definitions and approaches that mostly focus on a single phenomenon and conform to traditional disciplinary lines, making it difficult to fully understand informality and adequately inform policymaking. In this article, we carried out a multilevel co-word analysis with the purpose of unveiling the intellectual structure of socioeconomic informality. Co-occurring document keywords were used, initially, to delimit the scope of the socioeconomic dimension of informality (macro level) and, later, to identify its main concepts, themes (meso level) and sub-themes (micro level). Our results show that there is a corpus of research on socioeconomic informality that is sufficiently differentiable from other types of informality. This corpus, at the same time, can be divided into six major themes and 31 sub-themes related, more prominently, to the informal economy, informal settlements and informal institutions. Looking forward, the analysis suggests, an increasing focus on context and on the experience of multiple ‘informalities’ has the potential, on the one hand, to reveal links that help unify this historically fragmented corpus and, on the other hand, to give informality a meaning and identity that go beyond the traditional formal-informal dualism.

The effect of placing prophylactic abdominal drainage tube after hepatobiliary surgery on postoperative infection: A systematic review and meta‐analysis

Abstract

Whether prophylactic abdominal drainage tube is routinely placed in patients after hepatobiliary surgery remains controversial. To evaluate the effect of prophylactic abdominal drainage tube placement after hepatobiliary surgery on postoperative infection. Randomized controlled trials on the placement of prophylactic abdominal drainage tube after hepatobiliary surgery were collected through a computerized search of PubMed, Embase, Conchrane Library and Web of Science databases, with a time range from the establishment of the database to August 2023. After two researchers independently screened the literature, extracted information, and evaluated the quality of the included studies. Finally, 13 studies were included, including 3620 patients, and the results showed that there was no statistically significant difference in postoperative infection rate between the drainage group (1840 patients and the non-drainage group [1783 patients] [relative risk, RR = 1.17, 95% confidence interval, CI: 0.94–1.47, p = 0.16]. Compared with the drainage group, the incidence of infectious abdominal fluid in the non-drainage group was lower (RR = 2.09, 95% CI: 1.57–2.80, p < 0.00001), and the incidence of postoperative bile leakage was lower (RR = 1.77, 95% CI: 1.27–2.47, p < 0.001) and shorter hospital stays after surgery (mean difference = 1.27, 95% CI: 0.32–2.22, p = 0.009). In conclusion, placing a prophylactic abdominal drainage tube after hepatobiliary surgery does not reduce postoperative infection rates compared with no drainage.

The efficacy and safety of non‐surgical treatment of diabetic foot wound infections and ulcers: A systemic review and meta‐analysis

Abstract

This meta-analysis evaluates the efficacy and safety of non-surgical treatments for diabetic foot ulcers and infections. After a rigorous literature review, seven studies were selected for detailed analysis. The findings demonstrate that non-surgical treatments significantly reduce wound infection rates (standardized mean difference [SMD] = −15.15, 95% confidence interval [CI]: [−19.05, −11.25], p < 0.01) compared to surgical methods. Ulcer healing rates were found to be comparable between non-surgical and surgical approaches (SMD = 0.07, 95% CI: [−0.38, 0.51], p = 0.15). Importantly, the rate of amputations within 6 months post-treatment was significantly lower in the non-surgical group (risk ratio [RR] = 0.19, 95% CI: [0.09, 0.41], p < 0.01). Additionally, a lower mortality rate was observed in patients treated non-surgically (RR = 0.28, 95% CI: [0.13, 0.59], p < 0.01). These results affirm the effectiveness and safety of non-surgical interventions in managing diabetic foot ulcers, suggesting that they should be considered a viable option in diabetic foot care.

Integrated strategies for the clinical correlation, prevention and management of chronic oral infections, wounds and arteriosclerotic occlusion in lower extremities

Abstract

This study explores the intricate relationship between chronic periodontitis (CP) and its implications for wound healing, particularly in the context of arteriosclerotic occlusion (ASO) in the lower extremities. A cohort of 90 individuals was categorized into three groups: those with CP, those with both CP and ASO (ASO + CP) and a healthy control group. Comprehensive assessments including oral examinations, blood tests and questionnaires were conducted. Key oral health indicators such as probing depth (PD), bleeding on probing (BOP) and periodontal inflammatory surface area (PISA) were evaluated to gauge the severity of periodontal wounds. The study found that the ASO + CP group showed a significantly higher number of missing teeth and increased PD compared to the CP group (p < 0.05). Both CP and ASO + CP groups exhibited elevated PD, BOP and PISA compared to the control group (p < 0.05), indicating exacerbated periodontal wounds. Serum analyses showed heightened total cholesterol (TC) and high-sensitivity C-reactive protein (hs-CRP) levels in the ASO + CP group, suggesting a stronger inflammatory response and potential for atherogenesis. Interestingly, FPG and triglycerides (TG) levels did not significantly vary across groups (p > 0.05). Regression analysis identified PD (β = 2.271, p < 0.001) and PISA (β = 0.027, p = 0.001) as significant predictors for ASO presence in CP patients. The findings underscore the clinical correlation between chronic oral wounds in CP and the development of ASO in lower extremities, highlighting the critical need for integrated management strategies focusing on periodontal health to prevent and manage such complex conditions effectively. Elevated inflammatory markers in the ASO + CP group further reinforce the necessity for vigilant monitoring and targeted interventions in these patients.

Effect of a multidisciplinary team approach on the management of diabetic foot ulcers on the Central Coast: A review of the Gosford Hospital High‐Risk Foot Clinic

Abstract

This retrospective cohort study aims to assess whether the implementation of a multidisciplinary approach in the Gosford Hospital High-Risk Foot Clinic improved outcomes of diabetic foot ulcers. Ulceration is a common foot complication of diabetes mellitus and greatly increases patient morbidity and mortality. Patients who attended at least one appointment at the Gosford Hospital High-Risk Foot Clinic in 2017 or 2019 were identified through the Gosford Hospital Podiatry department's records. The 2017 and 2019 cohorts were compared on measures of ulcer healing, incidence of amputation, incidence of vascular intervention and surgical debridement, percentage of patients admitted to hospital due to complications and use of systemic antibiotic therapy. Sixty-one patients in 2017 and 59 patients in 2019 met inclusion criteria, and from them, 207 ulcers were included. Between 2017 and 2019, there was a 6.2-week reduction in time to 100% ulcer healing in 2019 (p = 0.021), and 10.1% more ulcers healed within 52 weeks (p = 0.22, 95% confidence interval [CI] [−5.9%, 25.5%]). Whilst there was no significant difference in incidence of patients receiving amputation, there was an increased absolute number of amputations in 2019. Implementation of a multidisciplinary approach at the Gosford Hospital High-Risk Foot Clinic led to improvements in diabetic foot ulcer healing.

Intimate partner violence and excess fertility among women of reproductive age in Malawi

by Sufia Dadabhai, Laura Quaynor, Antonio Bandala-Jacques, Linly Seyama, Md Hafizur Rahman, Richard Phiri, Michele R. Decker, Taha E. Taha

Purpose

Gender inequity and adverse health outcomes continue to be of concern among women in sub-Saharan Africa. We determined prevalence of intimate partner violence and excess fertility (having more children than desired) in reproductive age women in Malawi. We also explored factors associated with these outcomes and with spousal fertility intentions.

Patients and methods

In a cross-sectional study, a total of 360 women and 410 men were recruited using multi-stage sampling from communities in a peri-urban setting in Blantyre District, Southern Malawi in 2021. Women and men were separately interviewed by trained study workers using a structured questionnaire. In addition to descriptive analyses, we used univariate and multivariate logistic regression models to assess associations of risk factors with the outcomes of intimate partner violence and excess fertility.

Results

Among women, lifetime prevalence of intimate partner violence was 23.1%, and excess fertility was experienced by 25.6%. Intimate partner violence was associated with male partners alcohol consumption (adjusted odds ratio 2.13; P = 0.019). Women were more likely to report excess fertility if they were older (adjusted odds ratio 2.0, P Conclusions

Intimate partner violence, excess fertility, and social and health inequities continue to be prevalent in Malawi. These data suggest the underlying proximal and distal factors associated with these adverse outcomes such as alcohol consumption may be addressed through education, couple interactive communication, and community dialogue. To ensure sustainability and effectiveness, strong leadership involvement, both governmental and non-governmental, is needed.

Pleural effusion portends a poor prognosis in patients on continuous ambulatory peritoneal dialysis

by Fengping Zhang, Ting Xiang, Xiaoran Feng, Guilin Zhang, Yu Liu, Luohua Li

Aims

Pleural effusion is not an infrequent complication in patients undergoing continuous ambulatory peritoneal dialysis. However, there is not adequate data to evaluate pleural effusion and prognosis in clinical practice. In this study, we validated this potential association by a multicenter cohort.

Methods

We screened 1,162 patients who met the inclusion criteria with PD. According to the existence of pleural effusion on stable dialysis (4–8 weeks after dialysis initiation), the participants were divided into pleural effusion and non-pleural effusion groups. The hazard ratios (HRs) of all-cause and cause-specific death were estimated with adjustment for demographic characteristics and multiple potential clinical confounders. Subgroup analysis and propensity score matching (PSM) were used to further verify the robustness of the correlation between hydrothorax and prognosis.

Results

Pleural effusion was found in 8.9% (104/1162) of PD individuals. After adjusting for the confounding factors, patients with pleural effusion had significantly increased HRs for all-cause death was 3.06 (2.36–3.96) and cardiovascular death was 3.78 (2.67–5.35) compared to those without pleural effusion. However, it was not associated with infectious and other causes of death. After PSM, the HR of all-cause mortality was 3.56 (2.28–5.56). The association trends were consistent in the subgroup sensitivity analysis.

Conclusion

Pleural effusion is not rare in PD, and is significantly associated with overall and cardiovascular mortality, which is independent of underlying diseases and clinically relevant indicators.

Preliminary evidence for the validity of the Brief Post-Secondary Student Stressors Index (Brief-PSSI): A cross-sectional psychometric assessment

by Brooke Linden, Amy Ecclestone

The brief version of the Post-Secondary Student Stressors Index (Brief-PSSI) was developed in order to improve the usability of the instrument as a method for evaluating the severity and frequency of stressors faced by post-secondary students. While the original 46-item instrument has been thoroughly psychometrically validated and successfully used among student populations, the length of the instrument limits its utility. Providing a valid, shortened version of the PSSI will enable institutions to include the tool on existing online surveys currently being deployed to surveil the mental health and wellbeing of their students. This study reports preliminary evidence in support of the validity and reliability of the Brief-PSSI using a cross-sectional pilot sample of students attending an Ontario university in 2022. A total of 349 participants (average age 25 (SD = 7.7), range 19–60) completed the first survey, while 149 completed the follow-up survey (average age of 26 (SD = 7.7), range 17–60). Evidence of internal structure, relations to other variables, and of test-retest reliability was assessed according to established index validation guidelines, including the specification of multiple-indicator, multiple-cause models, and Spearman’s rho correlation coefficients. Results provide preliminary support for the validity and reliability of the tool, which demonstrated acceptable goodness-of-fit statistics, statistically significant relationships with like constructs in the hypothesized directions, and good test-retest reliability correlation coefficients. The Brief-PSSI is a useful tool for evaluating the sources of stress among post-secondary students, assessing both the severity of stress experienced and frequency with which each stressor occurred. Future research should explore the practical utility of adding the Brief-PSSI to existing survey assessments as well as pursue the continued collection of validation evidence for the tool among varied student populations.

Clinical evaluation of a fully electronic microfluidic white blood cell analyzer

by Jianye Sui, Zhongtian Lin, Shahriar Azizpour, Fei Chen, Sunanda Gaur, Kelly Keene, Farzad Soleimani, Tanaya Bhowmick, Zubaid Rafique, Mehdi Javanmard

The White Blood Cell (WBC) count is one of the key parameters signaling the health of the immune system. Abnormal WBC counts often signal a systemic insult to the body such as an underlying infection or an adverse side effect to medication. Typically, the blood collected is sent to a central lab for testing, and results come back within hours, which is often inconvenient and may delay time-sensitive diagnosis or treatment. Here, we present the CytoTracker, a fully electronic, microfluidic based instant WBC analyzer with the potential to be used at point-of-care. The CytoTracker is a lightweight, portable, affordable platform capable of quantifying WBCs within minutes using only 50 μl of blood (approximately one drop of blood). In this study, we clinically evaluated the accuracy and performance of CytoTracker in measuring WBC and granulocyte counts. A total of 210 adult patients were recruited in the study. We validated the CytoTracker against a standard benchtop analyzer (Horiba Point of Care Hematology Analyzer, ABX Micros 60). Linear dynamic ranges of 2.5 k/μl– 35 k/μl and 0.6 k/μl– 26 k/μl were achieved for total WBC count and granulocyte count with correlation coefficients of 0.97 and 0.98. In addition, we verified CytoTracker’s capability of identifying abnormal blood counts with above 90% sensitivity and specificity. The promising results of this clinical validation study demonstrate the potential for the use of the CytoTracker as a reliable and accurate point-of-care WBC analyzer.

D-dimer levels to exclude pulmonary embolism and reduce the need for CT angiography in COVID-19 in an outpatient population

by Anita Kovács, Dóra Hantosi, Nikoletta Szabó, Annamária Letoha, Csaba Lengyel, Imre Földesi, Katalin Burián, András Palkó, Dániel Veréb, Zsigmond Tamás Kincses

Objectives

Emerging results indicate that, in COVID-19, thromboembolic complications contribute to the high mortality and morbidity. Previous research showed that the prevalence of pulmonary embolism (PE) is between 25–50% in COVID-19 patients, however, most of these reports are based on data from patients with severe pneumonia, treated in intensive care units.

Materials and methods

We conducted a retrospective, single-center, observational study to estimate the prevalence of PE in COVID-19 patients who underwent CT angiography and to identify the most important predictors.Adult outpatients with COVID-19, who presented at our COVID Outpatient Clinic between 1st and 31st of March in 2021 and underwent CTA examination were included in this study. Multiple linear regression analysis was used to identify predictors of PE in COVID-19 patients. The predictors were: age, gender, disease duration, CT severity index and log-transformed quantitative D-dimer (logQDDIM) value.

Results

843 COVID-19 patients were included into the study. 82.56% (693 patients) of the infected patients had a pulmonary CTA examination and D-dimer levels (mean age: 59.82 years ± 15.66). 7.61% (53 patients) of the patients had PE. 2.02% (14 patients) of the patients had main branch or lobar PE.The multiple regression analysis found that only logQDDIM was a significant predictor. A logQDDIM cut-off value of 0.0169 (1.0171 ug/ml serum D-dimer) predicted PE with 99% sensitivity (p Conclusions

We demonstrated in a large cohort of COVID-19 patients that a cut-off value of QDDIM of 1ug/ml can exclude pulmonary embolism in an outpatient setting, implicating that QDDIM might potentially supersede CTA as a screening approach in COVID-19 outpatient clinics.

The impact of different antibiotic injection regimens on patients with severe infections: A meta‐analysis

Abstract

Severe infection is a critical health threat to humans, and antibiotic treatment is one of the main therapeutic approaches. Nevertheless, the efficacy of various antibiotic injection regimens in severe infection patients remains uncertain. This study aimed to comprehensively evaluate the impact of various antibiotic injection strategies on patients with severe infection through a meta-analysis. Relevant research literature was collected by searching databases such as PubMed, Embase, and Cochrane Library. The retrieved literature was screened according to inclusion and exclusion criteria. Relevant data, including study design, sample size, and antibiotic regimens, were extracted from the included studies. The Cochrane Collaboration's Risk of Bias tool was employed to assess the risk of bias in each study. Statistical analysis was performed based on the results of the included studies. A total of 15 articles were included, covering various types of severe infection patients, including pulmonary and abdominal infections. The analysis provided insights into mortality rates, treatment efficacy, adverse reactions (ARs), Acute Physiology and Chronic Health Evaluation (APACHE) scores, among other outcomes. The results indicated that combination therapy was superior to monotherapy in terms of mortality rate, treatment efficacy, and APACHE scores, while the incidence of ARs was lower in the monotherapy group compared to the combination therapy group (p < 0.05). Combination therapy showed better treatment efficacy compared to monotherapy, although it was associated with a higher incidence of ARs.

Exploring the resistance mechanism of triple-negative breast cancer to paclitaxel through the scRNA-seq analysis

by Wei Gao, Linlin Sun, Jinwei Gai, Yinan Cao, Shuqun Zhang

Background

The triple negative breast cancer (TNBC) is the most malignant subtype of breast cancer with high aggressiveness. Although paclitaxel-based chemotherapy scenario present the mainstay in TNBC treatment, paclitaxel resistance is still a striking obstacle for cancer cure. So it is imperative to probe new therapeutic targets through illustrating the mechanisms underlying paclitaxel chemoresistance.

Methods

The Single cell RNA sequencing (scRNA-seq) data of TNBC cells treated with paclitaxel at different points were downloaded from the Gene Expression Omnibus (GEO) database. The Seurat R package was used to filter and integrate the scRNA-seq expression matrix. Cells were further clustered by the FindClusters function, and the gene marker of each subset was defined by FindAllMarkers function. Then, the hallmark score of each cell was calculated by AUCell R package, the biological function of the highly expressed interest genes was analyzed by the DAVID database. Subsequently, we performed pseudotime analysis to explore the change patterns of drug resistance genes and SCENIC analysis to identify the key transcription factors (TFs). Finally, the inhibitors of which were also analyzed by the CTD database.

Results

We finally obtained 6 cell subsets from 2798 cells, which were marked as AKR1C3+, WNT7A+, FAM72B+, RERG+, IDO1+ and HEY1+HCC1143 cell subsets, among which the AKR1C3+, IDO1+ and HEY1+ cell subsets proportions increased with increasing treatment time, and then were regarded as paclitaxel resistance subsets. Hallmark score and pseudotime analysis showed that these paclitaxel resistance subsets were associated with the inflammatory response, virus and interferon response activation. In addition, the gene regulatory networks (GRNs) indicated that 3 key TFs (STAT1, CEBPB and IRF7) played vital role in promoting resistance development, and five common inhibitors targeted these TFs as potential combination therapies of paclitaxel were identified.

Conclusion

In this study, we identified 3 paclitaxel resistance relevant IFs and their inhibitors, which offers essential molecular basis for paclitaxel resistance and beneficial guidance for the combination of paclitaxel in clinical TNBC therapy.

Occurrence and characteristics of extended-spectrum-β-lactamase- and pAmpC-producing <i>Klebsiella pneumoniae</i> isolated from companion animals with urinary tract infections

by Megan Min Yi Lee, Nan-Ling Kuan, Zhi-Yi Li, Kuang-Sheng Yeh

This study examined 70 Klebsiella pneumoniae isolates derived from companion animals with urinary tract infections in Taiwan. Overall, 81% (57/70) of the isolates carried extended-spectrum β-lactamase (ESBL) and/or plasmid-encoded AmpC (pAmpC) genes. ESBL genes were detected in 19 samples, with blaCTX-M-1, blaCTX-M-9, and blaSHV being the predominant groups. pAmpC genes were detected in 56 isolates, with blaCIT and blaDHA being the predominant groups. Multilocus sequence typing revealed that sequence types (ST)11, ST15, and ST655 were prevalent. wabG, uge, entB, mrkD, and fimH were identified as primary virulence genes. Two isolates demonstrated a hypermucoviscosity phenotype in the string test. Antimicrobial susceptibility testing exhibited high resistance to β-lactams and fluoroquinolones in ESBL-positive isolates but low resistance to aminoglycosides, sulfonamides, and carbapenems. Isolates carrying pAmpC genes exhibited resistance to penicillin-class β-lactams. These findings provide valuable insights into the role of K. pneumoniae in the context of the concept of One Health.

Investigating how tamsulosin combined with levofloxacin impacts wound healing in patients with chronic prostatitis who may also have perineal or urethral wounds

Abstract

Chronic prostatitis, which frequently manifests with perineal or urethral ulcers, can have substantial impact on the quality of life experienced by affected individuals. Present treatment approaches primarily target the alleviation of symptoms and control of complications. In patients with chronic prostatitis, this investigation examined the potential synergistic effects of tamsulosin and levofloxacin on urinary function and urethral and perineal wounds healing. This cross-sectional observational study was carried out at Chongqing Western Hospital, China, from February to November 2023. The participants comprised 88 males aged 40–75 years who had been clinically diagnosed with chronic prostatitis and complications that accompany the wound healing process. The participants were equally distributed into two groups: one assigned to the treatment group, which received a daily combination of levofloxacin (500 mg) and tamsulosin (0.4 mg) and other to receive conventional care. The wound healing rate and improvement in urinary function were the primary outcomes evaluated monthly for 9 months. Patient satisfaction and symptom amelioration were secondary outcomes, in addition to the surveillance of adverse effects. In comparison to the control, treatment group exhibited significantly higher rate of wound closure (78.08% at 1 month and 79.38% at 9 months) and urinary function improvement (66.69% at 1 month and 67.95% at 9 months). In addition, the treatment group exhibited a greater degree of symptom amelioration; however, a rise in adverse effects was observed. In every domain, patient satisfaction scores were significantly higher in the treatment group. Thus the combination of tamsulosin and levofloxacin improved urinary function and wound repair in patients with chronic prostatitis, while also exhibiting tolerable profile of adverse effects.

Developing an early warning system for detecting sepsis in patients with trauma

Abstract

The purpose of this study was to analyse the risk factors for sepsis in patients with trauma and develop a new scoring system for predicting sepsis in patients with trauma based on these risk factors. This will provide a simple and effective early warning method for the rapid and accurate detection and evaluation of the probability of sepsis in patients with trauma to assist in planning timely clinical interventions. We undertook a retrospective analysis of the clinical data of 216 patients with trauma who were admitted to the emergency intensive care unit of the emergency medicine department of the Hebei Medical University Third Hospital, China, between November 2017 and October 2022. We conducted a preliminary screening of the relevant factors using univariate logistic regression analysis and included those factors with a p value of <0.075 in the multivariate logistic regression analysis, from which the risk factors were screened and assigned, and obtained a total score, which was the sepsis early warning score. The incidence of sepsis in patients in the intensive care unit with trauma was 36.9%, and the mortality rate due to sepsis was 19.4%. We found statistically significant differences in several factors for patients with sepsis. The risk factors for sepsis in patients with trauma were the activated partial thromboplastin time, the New Injury Severity Score, growth differentiation factor-15 levels, shock, mechanical ventilation and the Acute Physiology and Chronic Health Evaluation II score. The area under the receiver operating characteristic curve of the sepsis early warning score for predicting sepsis in patients with trauma was 0.725. When the cutoff value of the early warning score was set at 5.0 points, the sensitivity was 69.9% and the specificity was 60.3%. The incidence of sepsis in patients with trauma can be reduced by closely monitoring patients' hemodynamics, implementing adequate fluid resuscitation promptly and by early removal of the catheter to minimize the duration of unnecessary invasive mechanical ventilation. In this study, we found that the use of the sepsis early warning score helped in a more accurate and effective evaluation of the prognosis of patients with trauma.
