Exploring the association of weather variability on Campylobacter - A systematic review.

BACKGROUND: Previous work has found climate change-induced weather variability is suspected to increase the transmission of enteric pathogens, including Campylobacter, a leading cause of bacterial gastroenteritis. While the relationship between extreme weather events and diarrheal diseases has been documented, the specific impact on Campylobacter infections remains underexplored. OBJECTIVE: To synthesize the peer-reviewed literature exploring the effect of weather variability on Campylobacter infections in humans. METHODS: The review included English language, peer-reviewed articles, published up to September 1, 2022 in PubMed, Embase, GEOBASE, Agriculture and Environmental Science Database, and CABI Global Health exploring the effect of an antecedent weather event on human enteric illness caused by Campylobacter (PROSPERO Protocol # 351884). We extracted study information including data sources, methods, summary measures, and effect sizes. Quality and weight of evidence reported was summarized and bias assessed for each article. RESULTS: After screening 278 articles, 47 articles (34 studies, 13 outbreak reports) were included in the evidence synthesis. Antecedent weather events included precipitation (n = 35), temperature (n = 30), relative humidity (n = 7), sunshine (n = 6), and El Niño and La Niña (n = 3). Reviewed studies demonstrated that increases in precipitation and temperature were correlated with Campylobacter infections under specific conditions, whereas low relative humidity and sunshine were negatively correlated. Articles estimating the effect of animal operations (n = 15) found presence and density of animal operations were significantly associated with infections. However, most of the included articles did not assess confounding by seasonality, presence of animal operations, or describe estimates of risk. DISCUSSION: This review explores what is known about the influence of weather events on Campylobacter and identifies previously underreported negative associations between low relative humidity and sunshine on Campylobacter infections. Future research should explore pathogen-specific estimates of risk, which can be used to influence public health strategies, improve source attribution and causal pathways, and project disease burden due to climate change.

The downstream effects of COVID-19 on adolescent girls in the Peruvian Amazon: qualitative findings on how the pandemic affected education and reproductive health.

Due to COVID-19, schools were closed to mitigate disease spread. Past studies have shown that disruptions in education have unintended consequences for adolescents, including increasing their risk of school dropout, exploitation, gender-based violence, pregnancy and early unions. In Peru, the government closed schools from March 2020 to March 2022, declaring a national emergency that affected an estimated 8 million children. These closures may have unintended consequences, including increased adolescent pregnancy, particularly in Peru's rural, largely indigenous regions. Loreto, located in the Peruvian Amazon, has one of the highest adolescent pregnancy rates in the country and poor maternal and child health outcomes. The underlying causes may not be fully understood as data are limited, especially as we transition out of the pandemic. This qualitative study investigated the downstream effects of COVID-19 on adolescent education and reproductive health in Loreto's districts of Nauta and Parinari. In-depth interviews (n=41) were conducted with adolescents and community leaders. These were held in June 2022, 3 months after the reinstitution of in-person classes throughout Peru. Focus group discussions (FGDs) were also completed with community health workers and educators from the same study area in October 2022 to supplement our findings (3 FGDs, n=15). We observed that the economic, educational and health effects of the COVID-19 pandemic contributed to reduced contraceptive use, and increased school abandonment, early unions and adolescent pregnancy. The interplay between adolescent pregnancy and both early unions and school abandonment was bidirectional, with each acting as both a cause and consequence of the other.

Postoperative Prescribing Practices Following Gynecologic Surgery.

BACKGROUND: Opioids prescribed for postoperative pain have exceeded patient need in the United States, playing a significant role in the opioid epidemic. In the preintervention phase of this project (September 2018 - March 2019), a chart review and patient survey revealed that patients were prescribed double the number of opioids they consumed following gynecologic surgery. OBJECTIVE: To ascertain whether an educational intervention recommending opiate prescriptions based on postoperative opioid use decreases gynecologic surgeons' opiate prescriptions. METHODS: An educational intervention implemented in January 2021 communicated the discrepancy between patient need and medications prescribed and made prescribing recommendations for common gynecologic procedures. A postintervention (February 2021 - April 2021) retrospective chart review ascertained postoperative opioid prescribing practices. Residents were surveyed about their prescribing practices in June 2021. Descriptive statistics compared each phase. RESULTS: For laparoscopic hysterectomy, the median morphine milligram equivalent (MME) was 150 (IQR 112.5-166.9) for preintervention and 150 (IQR 112.5-150) postintervention. For vaginal hysterectomy, median MME declined from 150 (IQR 112.5-225) to 112.5 (IQR 112.5-150). For laparoscopic surgery without hysterectomy, the median MME was 75 for both preintervention (IQR 75-120) and postintervention (IQR 60-80). For vaginal surgery without hysterectomy median MME went from 75 (IQR 75-142.5) to 54 (IQR 22.5-112.5). Median MME for hysteroscopy and dilation and curettage was 0 for both phases. When surveyed, residents reported prescribing lower amounts than actual prescribing practices. CONCLUSIONS: Despite education informing gynecologic surgeons that their opioid prescribing exceeded patient need, prescribing practices did not change. The difference between actual and resident-reported prescribing practices warrants further investigation.

'You have a lot of mirrors': structural and socioecological factors impacting adolescent pregnancy and reproductive health in the Amazon basin, Peru, a qualitative study.

Loreto, in the Peruvian Amazon, has one of the highest adolescent pregnancy rates in the country. However, underlying causes of adolescent pregnancy are not fully understood as data are limited in Indigenous and remote Amazonian communities. This study investigated adolescent reproductive health within Loreto using an ecological systems framework. Forty-one semi-structured interviews were conducted in June 2022: community leaders (n = 12) and adolescent participants between 15 and 17 years of age (pregnant girls, n = 11; never pregnant girls, n = 9; and boys, n = 9). We also conducted focus group discussions with community health workers and educators in October 2022 (three focus groups, n = 15). Adolescent reproductive health is complex with multi-layered factors that put girls at higher risk of pregnancy. We found a paradoxical relationship between expected social and gender norms and individual desires. This research provides a contextual understanding of the lived experience of adolescents and young people in the Amazon region of Peru. Our findings suggest the need for greater exploration of the contradictory ideas surrounding adolescent pregnancy and female sexuality.

Antibiotic Resistance Rates for Helicobacter pylori in Rural Arizona: A Molecular-Based Study.

Helicobacter pylori (H. pylori) is a common bacterial infection linked to gastric malignancies. While H. pylori infection and gastric cancer rates are decreasing, antibiotic resistance varies greatly by community. Little is known about resistance rates among rural Indigenous populations in the United States. From 2018 to 2021, 396 endoscopy patients were recruited from a Northern Arizona clinic, where community H. pylori prevalence is near 60%. Gastric biopsy samples positive for H. pylori (n = 67) were sequenced for clarithromycin- and metronidazole-associated mutations, 23S ribosomal RNA (23S), and oxygen-insensitive NADPH nitroreductase (rdxA) regions. Medical record data were extracted for endoscopic findings and prior H. pylori history. Data analysis was restricted to individuals with no history of H. pylori infection. Of 49 individuals, representing 64 samples which amplified in the 23S region, a clarithromycin-associated mutation was present in 38.8%, with T2182C being the most common mutation at 90%. While the prevalence of metronidazole-resistance-associated mutations was higher at 93.9%, the mutations were more variable, with D95N being the most common followed by L62V. No statistically significant sex differences were observed for either antibiotic. Given the risk of treatment failure with antibiotic resistance, there is a need to consider resistance profile during treatment selection. The resistance rates in this population of American Indian patients undergoing endoscopy are similar to other high-risk populations. This is concerning given the high H. pylori prevalence and low rates of resistance testing in clinical settings. The mutations reported are associated with antibiotic resistance, but clinical resistance must be confirmed.

Twelve Month Outcomes of Pelvic Organ Prolapse Surgery in Patients With Uterovaginal or Posthysterectomy Vaginal Prolapse Enrolled in the Multicenter Pelvic Floor Disorders Registry.

OBJECTIVE: The aim of the study was to compare 12-month subjective and objective outcomes between 3 approaches to apical pelvic organ prolapse (POP) surgery in patients presenting with uterovaginal or posthysterectomy vaginal prolapse enrolled in the Pelvic Floor Disorders Registry for Research. STUDY DESIGN: This was an analysis of a multicenter, prospective registry that collected both patient- and physician-reported data for up to 3 years after conservative (pessary) and surgical treatment for POP. Twelve-month subjective and anatomic outcomes for patients who underwent surgical treatment were extracted from the registry for analysis. Pelvic organ prolapse recurrence was defined as a composite outcome and compared between the 3 apical surgery groups (native tissue repair, sacrocolpopexy, colpocleisis) as well as the 2 reconstructive surgery groups (native tissue repair and sacrocolpopexy). RESULTS: A total of 1,153 women were enrolled in the registry and 777 (67%) opted for surgical treatment, of whom 641 underwent apical repair and were included in this analysis (404 native tissue repair, 187 sacrocolpopexy, and 50 colpocleisis). The overall incidence of recurrence was as follows: subjective 6.5%, anatomic 4.7%, retreatment 7.2%, and composite 13.6%. The incidence of recurrence was not different between the 3 surgical groups. When baseline patient characteristics were controlled for, composite POP recurrence between the native tissue and sacrocolpopexy groups remained statistically nonsignificant. Concurrent perineorrhaphy with any type of apical POP surgery was associated with a lower risk of recurrence (adjusted odds ratio, 0.43; 95% confidence interval, 0.25-0.74; P = 0.002) and prior hysterectomy was associated with a higher risk (adjusted odds ratio, 1.77, 95% confidence interval, 1.04-3.03; P = 0.036). CONCLUSION: Pelvic Floor Disorders Registry for Research participants undergoing native tissue apical POP repair, sacrocolpopexy, and colpocleisis surgery had similar rates of POP recurrence 12 months after surgery.

Men and women experience different barriers to care seeking for fecal incontinence.

BACKGROUND: Despite effective treatments for fecal incontinence (FI), FI remains underdiagnosed and undertreated. This study sought to characterize and compare rates of, delays in, experiences with, and barriers to care seeking for FI among men and women. METHODS: This study was a secondary analysis of electronic survey data collected from adults with FI. The survey included the use of a validated instrument to assess FI severity and questions that now comprise a validated instrument for assessing barriers to care seeking for FI in women. Descriptive analyses characterized differences between men and women. χ2 testing for categorical variables and t-testing for normally distributed continuous variables compared statistical differences. RESULTS: The sample (N = 548) was predominately female (84%), non-Hispanic White (90%), and insured (96%), with a mean Vaizey score (13.4 ± 5.3) consistent with moderate or severe FI. Care seeking rates (p = 0.81) and symptom duration before care seeking (p = 0.23) did not differ between women and men, but women were more likely than men to be told that effective treatments exist; most male and female respondents who sought care were offered treatment. Very few respondents had been asked about FI by a healthcare provider. Whereas normative thinking, limited life impact, and believing that a healthcare provider could not help were more common barriers to care seeking among men, avoidance, fear, and discouragement were more common in women. CONCLUSIONS: Men and women with FI seek care at similar rates and after experiencing symptoms for a similar duration of time. Very few patients with FI have been screened for it by a healthcare provider. Barriers to FI care seeking are different for women and men, and men are less likely than women to be informed about effective treatments by a healthcare provider.

Fecal Incontinence and the Risk of Urinary Tract Infection in Patients Presenting for Urogynecological Consultation.

IMPORTANCE: Urinary tract infection (UTI) is common in urogynecology patients. Patients with fecal incontinence (FI) often attribute their UTIs to FI, but this association has not been evaluated. OBJECTIVES: The objectives of this study were to compare the prevalence of UTI in urogynecology patients with and without FI and to characterize factors associated with UTI and recurrent UTI. STUDY DESIGN: This retrospective cohort study included all new adult patients who presented to an academic female pelvic medicine and reconstructive surgery practice with FI from January 2014 through December 2017. Patients were age-matched to new adult patients with stage <2 pelvic organ prolapse without FI. All urine culture results from 1 year before and 1 year after the first visit were identified. Logistic regression identified factors associated with UTI. RESULTS: Among 399 patients, 106 (27%) had a culture-confirmed UTI in the year before or after their first urogynecology visit; the prevalence of UTI was 23% (45/198) in patients with FI and 30% (61/201) in those without FI (P = 0.09). The rate of recurrent UTI was 11.5% overall and did not differ among those with and without FI. In multivariate models, variables that were statistically significantly associated with UTI included age, diabetes mellitus, anterior vaginal wall prolapse, and sexual activity. Fecal incontinence was not associated with any or recurrent UTI. CONCLUSIONS: The prevalence of UTI and recurrent UTI was similar in urogynecology patients with and without FI. Variables that were associated with UTI risk included older age, sexual activity, diabetes mellitus, and anterior vaginal wall prolapse.

Comparison of Prognostic Factors for Merkel Cell Carcinoma, Mucosal Melanoma and Cutaneous Malignant Melanoma: Insights into Their Etiologies.

Little is known about the epidemiology of Merkel cell carcinoma (MCC) and mucosal melanoma (MM). Using the United States (US) National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) program data, we compared MCC and MM with cutaneous malignant melanoma (CMM) with respect to incidence rates and prognostic factors to better understand disease etiologies. We describe the proportional incidences of the three cancers along with their survival rates based on 20 years of national data. The incidence rates in 2000-2019 were 203.7 per 1,000,000 people for CMM, 5.9 per 1,000,000 people for MCC and 0.1 per 1,000,000 people for MM. The rates of these cancers increased over time, with the rate of MM tripling between 2000-2009 and 2010-2019. The incidences of these cancers increased with age and rates were highest among non-Hispanic Whites. Fewer MCCs and MMS were diagnosed at the local stage compared with CMM. The cases in the 22 SEER registries in California were not proportional to the 2020 population census but instead were higher than expected for CMM and MCC and lower than expected for MM. Conversely, MM rates were higher than expected in Texas and New York. These analyses highlight similarities in the incidence rates of CMM and MCC-and differences between them and MM rates-by state. Understanding more about MCC and MM is important because of their higher potential for late diagnosis and metastasis, which lead to poor survival.

Acknowledging the risk of suicidal ideation, depression, and anxiety in PAs.

ABSTRACT: The prevalence of suicidal ideation is unknown and limited information exists about depression and anxiety among physician associates/assistants (PAs). We set out to understand the degree of depression, anxiety, and suicidal ideation in PAs and PA students. In total, 728 PAs and 322 PA students took an online survey. Risk of depression and anxiety were present at higher levels in PA students compared with employed PAs. PA students indicated higher levels of suicidal ideation compared with clinically active PAs. One-third of those with suicidal ideation did not reveal it to anyone; among those who did, 16.2% feared the results of disclosure. This study establishes that PAs and PA students are at risk for suicidal ideation and often bypass help. The COVID-19 pandemic may have led to elevated rates of emotional distress, and longitudinal studies are needed to understand the basis for such ideation and if it is transitory.

Helicobacter pylori treatment knowledge, access and barriers: A cross-sectional study.

BACKGROUND: Helicobacter pylori (Hp) is among the most common bacterial infections in the world and one of the most common infectious agents linked to malignancy, gastric cancer (GC). Within the US there is high disparity in the rates of Hp infection and associated diseases. Hp infection is treatable, and knowledge may influence screening and treatment seeking behaviors. MATERIALS AND METHODS: In this cross-sectional study of 1042 respondents recruited from the Online Amazon MTurk platform, we sought to assess baseline knowledge of Hp and to gain insight into barriers related to Hp care. RESULTS: Just over half (52.3%) reported some prior knowledge of Hp with 11.7% (n = 122) reporting being treated for Hp themselves and 21.4% reporting family members diagnosed with Hp. Of respondents reporting prior treatment, 95 (78%) reported GI upset and 27 (21%) reported not completing medications. Specific to Hp and GC, 70% indicated that a belief that the treatment was worse than the symptoms would affect their willingness to seek care, while 81% indicated knowing Hp can cause GC would affect their treatment decisions and knowing their gastric symptoms were caused by Hp would affect their willingness to receive care. CONCLUSIONS: Knowledge of Hp in this US sample of online respondents is low and self-reported difficulties with treatment compliance is high. Increasing awareness of this infection and addressing the challenges to treatment compliance could potentially reduce rates of Hp antibiotic resistance and progression to GC or other complications of Hp infection.

Etiology and factors associated with urogenital fistula among women who have undergone cesarean section: a cross-sectional study.

BACKGROUND: The prevalence and impact of fistulas are more common in developing countries with limited access to emergency obstetric care. As a result, women in these settings often experience adverse psychosocial factors. The purpose of this study was to describe the characteristics of Congolese women who developed urogenital fistula following Cesarean sections (CS) to determine the characteristics associated with two etiologies: (1) prolonged obstructed labor; and (2) a complication of CS following obstructed labor. METHODS: We performed a cross-sectional study on abstracted data from all patients with urogenital fistula following CS who received care during a surgical campaign in a remote area of the Democratic Republic of the Congo (DRC). Descriptive analyses characterized patients with fistula related to obstructed labor versus CS. Univariate and multivariate logistic regression models identified factors associated with obstetric fistula after cesarean delivery following obstructed labor. Variables were included in the logistic regression models based upon biological plausibility. RESULTS: Among 125 patients, urogenital fistula etiology was attributed to obstructed labor in 77 (62%) and complications following CS in 48 (38%). Women with a fistula, attributed to obstructed labor, developed the fistula at a younger age (p = .04) and had a lower parity (p = .02). Attempted delivery before arriving at the hospital was associated with an increased risk of obstetric fistula after cesarean delivery following obstructed labor (p < .01). CONCLUSION: CS are commonly performed on women who arrive at the hospital following prolonged obstructed labor and fetal demise, and account for almost 40% of urogenital fistula. Obstetric providers should assess maternal status upon arrival to prevent unnecessary CS and identify women at risk of developing a fistula.

The malaria transmission in Anhui province China.

Plasmodium vivax and Plasmodium falciparum cases have opposite trends in Anhui China in the past decade. Long term and seasonal trends in the transmission rate of P. falciparum in Africa has been well studied, however that of P. vivax transmitted by Anopheles sinensis in China has not been investigated. There is a lot of work on the relationship between P. vivax cases and climatic factors in China, with sometimes contradicting results. However, how climatic factors affect transmission rate of P. vivax in China is unknown. We used Anhui province as an example to analyze the recent transmission dynamics where two types of malaria have been reported with differing etiologies. We examined breakpoints of the P. vivax and P. falciparum malaria long term dynamics in the recent decade. For locally transmitted P. vivax malaria, we analyzed the transmission rate and its seasonality using the combined human and mosquitos SIR-SI model with time-varied mosquito biting rate. We identified the effects of meteorological factors on the seasonality in transmission rate using a GAM model. For the imported P. falciparum malaria, we analyzed the potential reason for the observed increase in cases. The breakpoints of P. vivax and P. falciparum dynamics happened in a same year, 2010. The seasonality in the transmission rate of P. vivax malaria was high (42.4%) and was linearly associated with temperature and nonlinearly with rainfall. The abrupt increase in imported P. falciparum cases after the breakpoint was significantly related to the increased annual Chinese investment in Africa. Under the conditions of the existing vectors of malaria, long-term trends in climatic factors, and increasing trend in migration to/from endemic areas and imported malaria cases, we should be cautious of the possibility of the reestablishment of malaria in regions where it has been eliminated or the establishment of other vector-borne diseases.

Validation of the Surgical Preparedness Assessment in women with pelvic floor disorders.

INTRODUCTION AND HYPOTHESIS: We sought to further develop and validate the Surgical Preparedness Assessment (SPA) scale to evaluate patient preparedness for urogynecological surgery. METHODS: This was a planned ancillary analysis of a randomized controlled trial (RCT) evaluating the impact of a preoperative telehealth call on patient preparedness for urogynecological surgery. Patients completed the Preoperative Preparedness Questionnaire (PPQ), the modified Preparedness for Colorectal Cancer Surgery Questionnaire (PCSQ), the Pelvic Floor Distress Inventory (PFDI-20), the Satisfaction Decision Scale (SDS), and the Decision Regret Scale (DRS). Content validity was established through expert opinion and patient cognitive interviews. Factor analysis identified item grouping into domains. Cronbach's alpha reported internal consistency. Known group validity was assessed by comparing intervention arms. External validity was evaluated by comparing intervention arms and correlations with SDS and DRS. RESULTS: Eleven items and 3 domains met the criteria (information needs, satisfaction and pain, and catheterization). Cronbach's alpha values were acceptable for domains and ranged from 0.74 to 0.93. SPA scores did not correlate with other patient-reported outcomes. Mean SPA scores were lower among women who received a telehealth call vs those who did not (1.30 ± 0.31 vs 1.51 ± 0.44; p = 0.002). CONCLUSIONS: The content-valid SPA demonstrates high internal consistency and known group validity.

Screening and Treating Urinary Incontinence in Primary Care: A Missed Opportunity.

More than 60% of adult women in the United States have urinary incontinence (UI), with the prevalence increasing to over 80% in women over age 65. Despite its high prevalence, most patients do not seek care and few clinicians screen for UI. The Medicare Health Outcomes Survey queries patients about satisfaction with their provider's discussion and management of UI, but formal recommendations about screening, diagnosis, and treatment are lacking. This review presents a practical algorithm for primary care providers to incorporate management of UI into routine preventive care for women, and outlines UI prevalence, risk factors, screening, and non-surgical treatment options.

Outcomes of Pessary Use at 1 Year in Women Treated for Pelvic Organ Prolapse in a Large Multicenter Registry: Developed by the Pelvic Floor Disorders Registry.

IMPORTANCE: There is a lack of high-quality long-term follow-up regarding pessary treatment. Most studies are case series or retrospective with a small sample size and short-term follow-up. OBJECTIVES: This study aimed to evaluate differences in women who continue versus discontinue pessary use and the effectiveness, quality of life, and safety associated with pessary management at 1 year. STUDY DESIGN: This study analyzed a multicenter national registry following women for 3 years with vaginal prolapse treated with a pessary or surgery. The primary outcome of this analysis was to compare the difference in characteristics among those who continue versus discontinue pessary use at 12 months. RESULTS: Among 1,153 participants enrolled, 376 (32.6%) opted for a pessary, and 296 (78.7%) were successfully fitted. Data were available for 240 participants (81%). At 1 year, 62% (n = 148) were still using pessaries, and 38% (n = 92) had stopped with 25% opting for surgery. Most commonly reported de novo adverse effects were urinary leakage (16%), feeling or seeing a bulge (12%), and vaginal discharge (11%). There was no difference in baseline characteristics among women who continued versus discontinued pessary use. At 12 months, subjective symptoms were similar between groups, with similar change in symptoms from baseline on most validated instruments. Those who continued to use a pessary reported worse urinary symptoms due to de novo urinary leakage ( P = 0.01). CONCLUSIONS: At 1 year, most women successfully fitted with a pessary continued pessary use. Although there was a significant improvement in condition-specific quality of life and low rates of complications, approximately 40% of women discontinued pessary use by 12 months. We were unable to identify any baseline characteristics associated with pessary discontinuation.

The Role of Interpersonal Toxicity on Healthcare Students' Well-Being.

INTRODUCTION: Nearly half of all medical students suffer from burnout, which not only has detrimental effects on the students themselves but can transfer into the clinical realm. Yet, studies exploring burnout and interpersonal toxicity in physician assistant (PA) students are rare. This study examined the role that interpersonal toxicity and abuse play in PA student burnout. METHODS: Nearly 2500 PA students in the United States responded to a survey about well-being, stress, and experiences with interpersonal toxicity in PA school as part of a larger cross-sectional study on PA student experiences in their didactic and clinical years. The present research focuses on overall measures among all PA students, as well as differences between didactic and clinical students, including the extent to which experiences of interpersonal toxicity predict symptoms associated with burnout. RESULTS: Overall, PA students reported high levels of satisfaction and happiness in school and life, but enthusiasm for school decreased for clinical students. More than two-thirds of students reported moderate to high levels of life stress, and more than 9 in 10 reported moderate to high levels of school stress. Symptoms of burnout were reported by many students, with clinical students reporting interpersonal toxicity exposure more often than didactic students. Experiencing interpersonal toxicity or abuse predicted symptoms of burnout. DISCUSSION: While PA students report high levels of life and school satisfaction, given the high levels of stress also reported, burnout metrics and well-being programs are needed. PA programs should work to create a supportive and engaging educational environment to ensure students' long-term career success.
