ABSTRACT

INTRODUCTION: There are a growing number of surgical approaches for laparoscopic radical resection of right-sided colon cancer, while there are relatively few comparative analyses of the different surgical approaches.

OBJECTIVE: To evaluate the safety and efficacy of different surgical approaches (intermediate approach, caudolateral approach, caudolateral combined with intermediate approach) for laparoscopic radical resection of right-sided colon cancer by conducting a network meta-analysis (NMA).

METHOD: We searched PubMed, Web of science and China National Knowledge Infrastructure (CNKI) databases. We reviewed the Chinese and English literature on controlled studies of laparoscopic radical resection of right-sided colon cancer including intermediate approach, caudolateral approach and caudolateral combined with intermediate approach, reported from the establishment of the database to September 2023. The inclusion and exclusion criteria were independently conducted by two researchers and relevant data was extracted from the qualifying literature and analyzed using Stata15 software.

RESULTS: Nine controlled studies of relevance including 715 patients were screened with right-sided colon cancer. Net meta-analysis showed that compared with the intermediate approach, the caudolateral approach was superior to the intermediate approach in terms of operation time (SMD = 0.75, 95% CI = 0.38 ~ 1.12, P = 0.0001), and bleeding volume (SMD = 1.15, 95% CI = 0.18 ~ 2.13, P = 0.002), while the difference was not statistically significant among the caudolateral approach compared with the intermediate approach in terms of the number of lymph node dissection, postoperative complication rate, time to first postoperative flatus and postoperative hospitalization. Compared with the intermediate approach, the combined approach was superior to the intermediate approach in terms of operation time (SMD = -0.87, 95% CI = -1.22 ~ -1.52, P < 0.05), bleeding volume (SMD = -1.09, 95% CI = -1.98 ~ -0.19, P < 0.05), the number of lymph node dissection (SMD = 0.21, 95% CI = 0.01 ~ 0.41, P < 0.05), and postoperative complication rate (RR = 2.24, 95% CI = 1.21 ~ 4.13, P < 0.05), while the difference was no statistically significant among the combined approach compared with the intermediate approach in terms of time to first postoperative flatus and postoperative hospitalization. Compared with the caudolateral approach, there was no statistically significant difference between the caudolateral approach and the combined approach in terms of operation time, bleeding volume, the number of lymph node dissection, postoperative complication rate, time to first postoperative flatus and postoperative hospitalization. According to the results of the surface under the cumulative ranking curve (SUCRA), the caudolateral approach and the combined approach were superior to the intermediate approach in terms of operation time (SUCRA: 65.1%, 84.9%, 0), bleeding volume (SUCRA: 77%, 71.9%, 1%), the number of lymph node dissection (SUCRA: 49.6%, 90.8%, 9.7%), postoperative complication rate (SUCRA: 46.6%, 97.5%, 5.9%), time to first postoperative flatus (SUCRA: 67%, 77.8%, 5.2%), postoperative hospitalization (SUCRA: 30.8%, 96.4%, 22.8%).

CONCLUSION: The caudolateral combined with intermediate approach and the caudolateral approach are safer and more effective than the intermediate approach. According to the results of SUCRA, the combined approach is superior to the caudolateral approach in terms of operation time, the number of lymph node dissection, postoperative complication rate, time to first postoperative flatus and postoperative hospitalization, the caudolateral approach is superior to the combined approach in term of bleeding volume.

ABSTRACT

BACKGROUND: Decades of medical data show worse patient outcomes among racial and gender minorities due to implicit, explicit, and structural biases. Increasing representation of marginalized groups among care providers is imperative to help address this. Limited literature exists on bias awareness strategies for interviewers during the selection of applicants to General Internal Medicine (GIM) programs in Canada. This study examines the trial of bias reduction tools to increase interviewers’ awareness of implicit biases.

METHODS: The Model of Improvement framework guided the trail of an instructional video, the adapted implicit association test (IAT), and a paper awareness tool (PAT) to increase interviewers’ awareness of implicit biases during the University of Alberta’s GIM applicant selection. An anonymous online survey was disseminated to physician interviewers. Descriptive statistics (percentages) and a modified sentiment analysis was completed.

RESULTS: 10 of 14 interviewers completed the survey. Respondents reported an increased awareness of using bias reduction tools (IAT, 25%; video, 71%; PAT, 67%) to inform them on their implicit biases. The future use of IAT, video, and PAT was supported by 50%, 71%, and 67% of interviewers, respectively.

CONCLUSIONS: Interviewers prefer the instructional video and PAT over the IAT. Textual responses suggest existing concerns for biases inherent to the interview process yet 70% (7/10) of respondents believe that interviews should have a weighting of 50% towards final ranking of candidates. As many institutions continue to rely on interviews to evaluate candidates, our findings indicate the need for a national study to develop a framework to mitigate inherent biases during interviewing of candidates.

ABSTRACT

BACKGROUND: Community-based participatory research (CBPR) is a collaborative research approach that engages academic researchers and community stakeholders as equal partners in all research steps to address community concerns and achieve health equity. The CBPR approach has been widely used in vaccination promotion programmes. However, the elements and steps of CBPR-based programmes varied among studies. The purpose of this scoping review was to synthesize the elements and steps, and establish an implementation framework to guide the utilisation of CBPR approaches in vaccination promotion.

METHODS: This scoping review was performed in accordance with Arksey and O’Malley’s five-stage framework. A systematic search was conducted on a set of electronic databases and grey literature sources. The retrieved articles were screened according to the criteria of CBPR and vaccination promotion, and data were extracted and recorded on a calibrated and predefined form in terms of study characteristics and CBPR components. Two authors worked independently to complete literature search, study selection, and data extraction. A narrative summary was used in categorising characteristics, and the contents of the included studies were summarised through qualitative analysis.

RESULTS: A total of 8557 publications were initially screened, and 23 articles were finally included. According to the CBPR conceptual model, the elements in each CBPR component specifically for vaccination promotion included (1) the establishment of community-academic partnership (CAP)s, (2) community capacity building by partner training vaccination knowledge, research literacy, and service abilities and skills, (3) development and implementation of community-based intervention and (4) Outcome evaluation. A CAP was established between academic researchers or institutes and eight types of partners, including community service organisation-related non-government organisations (NGOs), health service institution-related NGOs, religious organisations, government agencies, educational institutions, media agencies, business agencies, and community representatives. The maintenance of CAP was achieved with four key strategies, namely, strengthening communication, forming management groups, sharing resources and information, and providing incentives. Twelve studies provided comprehensive insights into the strategies employed for intervention development, utilising either quantitative surveys, qualitative methods or a combination of both approaches. The contents of interventions included health service supports, health education activities, social marketing campaigns, community mobilisation, interactive discussions, vaccination reminders and incentives. As for outcome evaluation, vaccination rate and the effectiveness of interventions were assessed. A considerable increase was observed in 95.7% of the included studies (22/23), and the highest increase (92.9%) was attained after the intervention. An implementation framework was generated to summarise the elements and steps of CBPR approaches for vaccination promotion.

CONCLUSIONS: This review summarised current evidence and generated an implementation framework to elucidate the elements and steps in the development and application of CBPR approaches in vaccination promotion. CBPR approaches are recommended for future vaccination promotion programmes, involving community stakeholders and research professionals, to ensure equitable access to vaccinations across diverse populations.

ABSTRACT

AIM: Our aim was to assess the burden of children and adolescents’ mental health problems on the Slovenian outpatient healthcare system before, during and after the pandemic.

METHODS: In a retrospective analysis of healthcare indicators from 2008 to 2023, we analysed data from the National Institute of Public Health. Key domains included initial visits for mental and behavioural disorders (MBDs) to primary care for the population aged 0-19; the number of referrals to an initial assessment with a child and adolescent psychiatrist (CAP) at the secondary level for the population aged 0-17 along with the corresponding waiting times; and the number of urgent referrals for the population aged 0-17 to emergency mental health centres at the tertiary level. The calculations included rates per 1000 people. Descriptive statistics and diagrams were used to compare the data. Segmented linear regression analysis (SLR) was conducted on the primary healthcare data to identify the distinct temporal point indicating an increase.

RESULTS: Comparing the average rates of the 2020-2022 period to those of the 2018-2019 period, there was a 20% increase in initial visits to primary care, a 23% increase in the referral rate to a CAP at the secondary level, and a 41% increase to the tertiary level of care. In secondary care, a four- to sevenfold increase in waiting times for the initial CAP assessment was observed between 2019 and 2023. The incidence of initial visits to primary healthcare services for MBD increased from 2008 to 2019 (average annual growth rate of 4.5%). The average annual growth rate for the 2020-2022 period tripled to 13.9%. The SLR showed that the trend of accelerating growth could have begun in 2017 for the 0-5 age group and possibly for the 15-19 age group as well.

CONCLUSIONS: After the initial decline in 2020, all levels of the Slovenian healthcare system faced an increased burden of MBD in children and adolescents from 2021 to 2022 compared to pre-pandemic levels. Nevertheless, a portion of this increase aligns with longitudinal growing trends from 2008 onwards. Tackling the crisis requires urgent national action, significant improvement in organization, and investments in mental health.

ABSTRACT

BACKGROUND: Bovine respiratory disease (BRD) is common in intensively raised cattle and is often treated with antibiotics. For practitioners, knowledge of the bacteria involved in an outbreak and their antibiotic susceptibility is warranted. To this end, samples from the upper or lower respiratory tract of calves can be submitted for bacteriological culture and susceptibility testing of relevant isolates. However, it is debated whether isolates from the upper respiratory tract are representative of bacteria causing infections in the lower respiratory tract. In this study, we used MALDI-TOF MS, multilocus sequence typing (MLST) and core-genome multilocus sequence typing (cgMLST) to compare culture results of 219 paired samples (sample pairs) of deep nasal swabs (DNS) and tracheobronchial lavage (TBL). The sample pairs came from 171 calves in 30 calf groups across 25 farms with 48 calves sampled twice.

RESULTS: The predominant bacterial pathogen was Pasteurella multocida, which was isolated from 37.4% of DNS and 22.4% of TBL. There was no statistically significant difference in isolation frequency of P. multocida between calves considered healthy and those suspected for BRD for DNS (P = 0.778) or TBL (P = 0.410). Among the 49 sample pairs where P. multocida was isolated from TBL, the same species was isolated from DNS in 29 sample pairs (59.2%). Isolates from 28 of these sample pairs were evaluated by MLST, and in 24 pairs (86.0%) P. multocida from DNS and TBL were of the same sequence type (ST). Moreover, cgMLST showed that the genetic distance between isolates within 21 of the 28 sample pairs (75.0%), was less than two alleles, and DNS and TBL isolates were considered identical. In seven sample pairs (25%), the genetic distance was greater, and DNS and TBL isolates were considered nonidentical.

CONCLUSIONS: Pasteurella multocida was readily isolated from DNS and in calves where this species was isolated also from TBL, DNS and TBL isolates were identical in 75% of the sample pairs. This suggests that during an outbreak of BRD, submission of DNS samples from 4 to 6 calves could be a convenient approach for practitioners seeking guidance on P. multocida present in the lower respiratory tract and their antibiotic susceptibility.

ABSTRACT

INTRODUCTION/BACKGROUND: Peer-led teaching sessions (PLTS) supplement conventional medical education, allowing students to share knowledge effectively. PLTS have shown significant academic benefits for student instructors. However, the impact on attendees, especially concerning NBME-style examinations, remains underexplored.

METHODS: This study analyzed de-identified data from 67 first-year medical students at Kirk Kerkorian School of Medicine, divided into PLTS attendees (study group) and non-attendees (control group) based on session participation. Data were collected before two NBME examinations, with attendees defined as those attending at least five Peer-led teaching sessions. Academic performance was measured using NBME Customized Assessment Services (CAS) exam scores. Statistical analyses, including p-tests, chi-square, and t-tests, assessed differences in performance and potential biases based on MCAT scores, first-generation status, and socioeconomic background.

RESULTS: The study group initially had 26 students, and the control group had 31 students. Post-first examination, the study group adjusted to 22 students, and the control group to 35 students. MCAT scores and demographics showed no significant differences between groups. The first examination revealed a significant higher score in PLTS attendees’ scores (4.28% increase, p = 0.036), indicating a positive impact of PLTS on basic science knowledge. The second examination on organ systems physiology showed no significant difference (p = 0.722).

DISCUSSION: PLTS effectively enhance foundational science understanding but may be less impactful for advanced topics. The diminishing effect may result from increased use of diverse study resources and adaptation to medical school. Future research should explore long-term benefits, optimal implementation strategies, and the impact of instructor quality and engagement. Therefore, the overall conclusion is that PLTS positively influence NBME-style exam performance in early medical education, but benefits decrease over time.

ABSTRACT

BACKGROUND: There is no pooled evidence regarding the prevalence and potential factors associated with depression among women with urinary incontinence worldwide. Hence, a systematic review and meta-analysis were conducted to determine the overall prevalence of depression among urinary incontinent women globally and explore any heterogeneity present.

METHODS: A computerized systematic literature search was performed using the Scopus, PubMed, Embase, Google Scholar, and Snowballing databases. Each database was searched from its start date of March 20, 2023. The study conforms to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. All included articles were published in English and evaluated the prevalence and associated factors of depression among urinary incontinent female patients. Pooled estimations with a 95% confidence interval (CI) were calculated with the DerSimonian‒Laird (DL) random-effects model. Publication bias was evaluated by using funnel plots and statistical tests.

RESULTS: Our initial electronic database search with the chosen search terms identified 1120 articles in PubMed (35 4), Embase (105), Scopus (325) and Google Scholar (176). The results of the 8 studies reporting a binary outcome using the different validation scales are summarized in the overall prevalence of depression was 18% (95% CI = 11-25%). Unable to read and write (OR: 1.34, 95% CI: [1.01, 1.78], I²= 0%), caesarean delivery (OR: 1.48, 95% CI: [1.30, 1.70], I² = 0%), obesity (OR: 1.37, 95% CI: [1.19, 1.58], I² = 0%), party greater than three (OR: 1.26, 95% CI: [0.98, 1.62], I²= 0%), comorbidity (OR: 1.32, 95% CI: [1.16, 1.49], I² = 85.3%), smoking (OR: 1.58, 95% CI: [0.99, 1.92], I2 = 0%) and single, divorced and widowed (OR: 1.67, 95% CI: [1.45, 1.92], I² = 0%) were the major factors associated with depression.

CONCLUSION AND RECOMMENDATIONS: This review demonstrated the high prevalence of depression among women with urinary incontinence. Being unable to read and write, delivery via caesarean section, obesity, having more than three children, having comorbidities, smoking, being single, being divorced and being widowed were all associated factors. This study identified that there was a strong association between urinary incontinence and depression. Future studies recommend focusing on the causal association between depression and urinary incontinence.

ABSTRACT

BACKGROUND: Endometriosis is a chronic, estrogen-dependent, benign condition, affecting 10-15% of women of reproductive age. It is associated with a prevalence of sexual dysfunction that is nearly twice as high as that seen in women with other benign gynecological conditions. Our study aimed to assess the effect of surgical intervention on sexual function, as measured by the FSFI (Female Sexual Function Index) score, in women with endometriosis compared to those with other benign gynecological conditions, both before and after surgery.

METHODS: A comparative analysis was conducted at the Medical University of Vienna from 2015 to 2020. The study included patients suspected of having endometriosis, fibroids, adnexal cysts, and/or infertility. Based on findings during surgery, patients were categorized into two groups: those with endometriosis (n = 64) and control patients (n = 38). All participants completed the FSFI questionnaire before surgery and again 8 to 18 weeks after the operation.

RESULTS: No significant differences were observed in the preoperative FSFI scores between the endometriosis patients and the control group. Similarly, no significant differences were found between the two groups in postoperative scores. However, in women diagnosed with endometriosis, surgical removal of endometriotic lesions significantly increased their full-scale FSFI score, and resulted in a significant improvement in the areas “desire” and “satisfaction”. Improvements were noted in all other areas as well, though they were not statistically significant.

CONCLUSIONS: Our research indicates that the surgical removal of endometriotic lesions can lead to an improvement in sexual function, as measured by the FSFI, within 8 to 18 weeks post-surgery. This improvement was not observed in the control group, which underwent surgery for other benign gynecological issues.

ABSTRACT

BACKGROUND: Problem-solving interventions with workplace involvement (PSI-WPI) have been shown to reduce sick leave and increase return to work in an occupational health services context. However, many employees struggle with reduced work functioning, anxiety-, and depressive symptoms up to 12 months after a sick leave episode, and it is unclear if the intervention affects outcomes other than sick leave. The aim of this study is to investigate if a PSI-WPI added to care as usual (CAU) is superior to CAU with respect to self-reported sick leave, psychological symptoms, work ability, work performance, and health after RTW when provided in primary care.

METHODS: Employed individuals aged 18-59 years on sick leave (2 to 12 weeks) diagnosed by a physician at a primary care center with mild to moderate depression, anxiety, or adjustment disorder were enrolled in a two-armed cluster-randomised trial evaluating the effectiveness of a PSI-WPI. Multiple outcomes were recorded at baseline, six months, 12 months, and every fourth week during the study period. Outcomes were categorised into psychological symptoms, health, work ability, work performance, and self-reported sick leave. Data were analysed using MANOVA, GEE (Generalized Estimating Equations), and cox regression.

RESULTS: One hundred ninety-nine individuals responded to the invitation to participate; one participant withdrew, one was excluded as the employment ended, nine did not answer the baseline survey, and three were removed from the analysis due to missing data. The analysis included 81 subjects who received the intervention and 104 subjects who received the control. Baseline characteristics were similar across both groups. No differences between the groups were found among either variables except one. There was a significant difference between the groups in self-rated health (EQ5D) in favour of the CAU group from baseline to six-month follow-up, with a mean difference of -8.44 (-14.84, -2.04).

CONCLUSIONS: A problem-solving intervention with workplace involvement added to CAU did not result in statistically significant reductions in outcomes. Further research is needed to understand why problem-solving interventions appear to have an effect on sick leave in an occupational health services context and not in a primary care context.

ABSTRACT

PURPOSE: Upper urinary tract stones are a common condition in urology clinics. Percutaneous nephrolithotomy (PCNL) is an effective procedure frequently used for the treatment of stones larger than 2 cm. MAP scoring is used to predict oncological outcomes and intraoperative complications after partial nephrectomy by using the thickness and adhesion of perinephric adipose tissue. We examined the relationship between MAP score and clinical and demographic findings of the patients, especially postoperative Hgb drop and postoperative complications.

MATERIAL-METHOD: Patients were divided into 2 groups: Those with MAP score < 3 and ≥ 3. The impact of the MAP score on the demographic, clinical, and surgical parameters of the groups was assessed and analyzed. The relationship between MAP score and complications based on Clavien Dindo classification was also examined. The study investigated factors affecting the development of complications, the amount of bleeding, and the influence of MAP scores on these outcomes.

RESULTS: The Hgb drop was 2.56 ± 1.00 in the group with a MAP score ≥ 3 which was statistically significantly higher than the group with a MAP score < 3 (1.43 ± 1.21) (p < 0.001). The stone-free rate was 81.7% in the group with a MAP score < 3, which was statistically significantly higher than the group with a MAP score ≥ 3 (59.6%) (p = 0.012).

CONCLUSION: As the MAP score of patients scheduled for standard PNL operation increased, there was a corresponding rise in Hgb drop, a decline in stone-free rates and an uptick in postoperative urinary complications of postoperative urinary infections.
