RESUMO

BACKGROUND: As the COVID-19 pandemic evolves, it is critical to understand characteristics that have allowed US healthcare systems, including the Veterans Affairs (VA) and non-federal hospitals, to mount an effective response in the setting of limited resources and unpredictable clinical demands generated by this system shock. OBJECTIVE: To compare the impact of and response to resource shortages to both VA and non-federal healthcare systems during the COVID-19 pandemic. DESIGN: Cross-sectional national survey administered April 2021 through May 2022. PARTICIPANTS: Lead infection preventionists from VA and non-federal hospitals across the US. MAIN MEASURES: Surveys collected hospital demographic factors along with 11 questions aimed at assessing the effectiveness of the hospital's COVID response. KEY RESULTS: The response rate was 56% (71/127) from VA and 47% (415/881) from non-federal hospitals. Compared to VA hospitals, non-federal hospitals had a larger average number of acute care (214 vs. 103 beds, p<.001) and intensive care unit (24 vs. 16, p<.001) beds. VA hospitals were more likely to report no shortages of personal protective equipment or medical supplies during the pandemic (17% vs. 9%, p=.03) and more frequently opened new units to care specifically for COVID patients (71% vs. 49%, p<.001) compared with non-federal hospitals. Non-federal hospitals more frequently experienced increased loss of staff due to resignations (76% vs. 53%, p=.001) and financial hardships stemming from the pandemic (58% vs. 7%, p<0.001). CONCLUSIONS: In our survey-based national study, lead infection preventionists noted several distinct advantages in VA versus non-federal hospitals in their ability to expand bed capacity, retain staff, mitigate supply shortages, and avoid financial hardship. While these benefits appear to be inherent to the VA's structure, non-federal hospitals can adapt their infrastructure to better weather future system shocks.

RESUMO

The burden of depression and anxiety disorders is high in sub-Saharan Africa, especially for people with HIV (PWH). The Patient Health Questionnaire-4 (PHQ-4) and Electronic Mental Wellness Tool-3 (E-mwTool-3) are ultra-brief screening tools for these disorders. We compared the performance of PHQ-4 and E-mwTool-3 for screening MINI-International Neuropsychiatric Interview diagnoses of depression and anxiety among a sample of individuals with and without HIV in two primary care clinics and one general hospital in Maputo City, Mozambique. Areas-under-the-curve (AUC) were calculated along with sensitivities and specificities at a range of cutoffs. For PWH, at a sum score cutoff of ≥ 1, sensitivities were strong: PHQ-4:Depression = 0.843; PHQ-4:Anxiety = 0.786; E-mwTool-3:Depression = 0.843; E-mwTool-3:Anxiety = 0.929. E-mwTool-3 performance was comparable to PHQ-4 among people with and without HIV.

RESUMO

INTRODUCTION: Lower adherence to antiretroviral treatment (ART) has been found among people with HIV (PWH) who have comorbid mental disorders like depression and alcohol use in Sub-Saharan African. However, there has been less exploration with regards to other mental disorders. METHODS: This study assessed the association of multiple mental disorders and adherence to ART based on the data from primary/tertiary health care facilities in Maputo and Nampula, Mozambique. We administered a sociodemographic questionnaire, Mini International Neuropsychiatric Interview (MINI) Plus 4.0.0 adapted for use in Mozambique to assess mental conditions, and a 3-item self-report to measure ART adherence. RESULTS: 395 HIV-positive (self-report) participants on ART, with an average age of 36.7 years (SD = 9.8), and 30.4% were male. The most common mental disorders were major depressive disorder (27.34%) followed by psychosis (22.03%), suicidal ideation/behavior (15.44%), and alcohol-use disorder (8.35%). Higher odds of missing at least one dose in the last 30 days (OR = 1.45, 95% CI: 1.01, 2.10) were found in participants with any mental disorder compared to those without a mental disorder. The highest levels of non-adherence were observed among those with drug use disorders and panic disorder. CONCLUSIONS: In Mozambique, PWH with any co-occurring mental conditions had a lower probability of ART adherence. Integrating comprehensive mental health assessment and treatment and ART adherence interventions tailored to PWH with co-occurring mental disorders is necessary to attain optimal ART adherence and reach the UNAIDS ART target.

RESUMO

BACKGROUND: Harmful alcohol use is defined as unhealthy alcohol use that results in adverse physical, psychological, social, or societal consequences and is among the leading risk factors for disease, disability and premature mortality globally. The burden of harmful alcohol use is increasing in low- and middle-income countries (LMICs) and there remains a large unmet need for indicated prevention and treatment interventions to reduce harmful alcohol use in these settings. Evidence regarding which interventions are effective and feasible for addressing harmful and other patterns of unhealthy alcohol use in LMICs is limited, which contributes to this gap in services. OBJECTIVES: To assess the efficacy and safety of psychosocial and pharmacologic treatment and indicated prevention interventions compared with control conditions (wait list, placebo, no treatment, standard care, or active control condition) aimed at reducing harmful alcohol use in LMICs. SEARCH METHODS: We searched for randomized controlled trials (RCTs) indexed in the Cochrane Drugs and Alcohol Group (CDAG) Specialized Register, the Cochrane Clinical Register of Controlled Trials (CENTRAL) in the Cochrane Library, PubMed, Embase, PsycINFO, CINAHL, and the Latin American and Caribbean Health Sciences Literature (LILACS) through 12 December 2021. We searched clinicaltrials.gov, the World Health Organization International Clinical Trials Registry Platform, Web of Science, and Opengrey database to identify unpublished or ongoing studies. We searched the reference lists of included studies and relevant review articles for eligible studies. SELECTION CRITERIA: All RCTs comparing an indicated prevention or treatment intervention (pharmacologic or psychosocial) versus a control condition for people with harmful alcohol use in LMICs were included. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. MAIN RESULTS: We included 66 RCTs with 17,626 participants. Sixty-two of these trials contributed to the meta-analysis. Sixty-three studies were conducted in middle-income countries (MICs), and the remaining three studies were conducted in low-income countries (LICs). Twenty-five trials exclusively enrolled participants with alcohol use disorder. The remaining 51 trials enrolled participants with harmful alcohol use, some of which included both cases of alcohol use disorder and people reporting hazardous alcohol use patterns that did not meet criteria for disorder. Fifty-two RCTs assessed the efficacy of psychosocial interventions; 27 were brief interventions primarily based on motivational interviewing and were compared to brief advice, information, or assessment only. We are uncertain whether a reduction in harmful alcohol use is attributable to brief interventions given the high levels of heterogeneity among included studies (Studies reporting continuous outcomes: Tau² = 0.15, Q =139.64, df =16, P<.001, I² = 89%, 3913 participants, 17 trials, very low certainty; Studies reporting dichotomous outcomes: Tau²=0.18, Q=58.26, df=3, P<.001, I² =95%, 1349 participants, 4 trials, very low certainty). The other types of psychosocial interventions included a range of therapeutic approaches such as behavioral risk reduction, cognitive-behavioral therapy, contingency management, rational emotive therapy, and relapse prevention. These interventions were most commonly compared to usual care involving varying combinations of psychoeducation, counseling, and pharmacotherapy. We are uncertain whether a reduction in harmful alcohol use is attributable to psychosocial treatments due to high levels of heterogeneity among included studies (Heterogeneity: Tau² = 1.15; Q = 444.32, df = 11, P<.001; I²=98%, 2106 participants, 12 trials, very low certainty). Eight trials compared combined pharmacologic and psychosocial interventions with placebo, psychosocial intervention alone, or another pharmacologic treatment. The active pharmacologic study conditions included disulfiram, naltrexone, ondansetron, or topiramate. The psychosocial components of these interventions included counseling, encouragement to attend Alcoholics Anonymous, motivational interviewing, brief cognitive-behavioral therapy, or other psychotherapy (not specified). Analysis of studies comparing a combined pharmacologic and psychosocial intervention to psychosocial intervention alone found that the combined approach may be associated with a greater reduction in harmful alcohol use (standardized mean difference (standardized mean difference (SMD))=-0.43, 95% confidence interval (CI): -0.61 to -0.24; 475 participants; 4 trials; low certainty). Four trials compared pharmacologic intervention alone with placebo and three with another pharmacotherapy. Drugs assessed were: acamprosate, amitriptyline, baclofen disulfiram, gabapentin, mirtazapine, and naltrexone. None of these trials evaluated the primary clinical outcome of interest, harmful alcohol use.   Thirty-one trials reported rates of retention in the intervention. Meta-analyses revealed that rates of retention between study conditions did not differ in any of the comparisons (pharmacologic risk ratio (RR) = 1.13, 95% CI: 0.89 to 1.44, 247 participants, 3 trials, low certainty; pharmacologic in addition to psychosocial intervention: RR = 1.15, 95% CI: 0.95 to 1.40, 363 participants, 3 trials, moderate certainty). Due to high levels of heterogeneity, we did not calculate pooled estimates comparing retention in brief (Heterogeneity: Tau² = 0.00; Q = 172.59, df = 11, P<.001; I2 = 94%; 5380 participants; 12 trials, very low certainty) or other psychosocial interventions (Heterogeneity: Tau² = 0.01; Q = 34.07, df = 8, P<.001; I2 = 77%; 1664 participants; 9 trials, very low certainty). Two pharmacologic trials and three combined pharmacologic and psychosocial trials reported on side effects. These studies found more side effects attributable to amitriptyline relative to mirtazapine, naltrexone and topiramate relative to placebo, yet no differences in side effects between placebo and either acamprosate or ondansetron. Across all intervention types there was substantial risk of bias. Primary threats to validity included lack of blinding and differential/high rates of attrition. AUTHORS' CONCLUSIONS: In LMICs there is low-certainty evidence supporting the efficacy of combined psychosocial and pharmacologic interventions on reducing harmful alcohol use relative to psychosocial interventions alone. There is insufficient evidence to determine the efficacy of pharmacologic or psychosocial interventions on reducing harmful alcohol use largely due to the substantial heterogeneity in outcomes, comparisons, and interventions that precluded pooling of these data in meta-analyses. The majority of studies are brief interventions, primarily among men, and using measures that have not been validated in the target population. Confidence in these results is reduced by the risk of bias and significant heterogeneity among studies as well as the heterogeneity of results on different outcome measures within studies. More evidence on the efficacy of pharmacologic interventions, specific types of psychosocial interventions are needed to increase the certainty of these results.

RESUMO

Multiple factors contribute to co-occurring issues such as violence, HIV, and mental disorders among people who inject drugs (PWID), particularly those residing in limited resource settings. Using an ecological framework, this study explored multilevel determinants of co-occurring violence, HIV, mental health, and substance use issues among PWID. Data were collected via semi-structured in-depth interviews with 31 men and women PWID in India. Findings revealed factors at the community (e.g., stigma), interpersonal (e.g., abusive partners), and individual (e.g., financial stress) levels. Findings highlight the need for prevention and intervention programs addressing factors at multiple ecological levels to reduce comorbidity among PWID.

RESUMO

BACKGROUND: Strategies to optimize antibiotic prescribing at discharge are not well understood. METHODS: In fall 2019, we surveyed 39 Michigan hospitals on their antibiotic stewardship strategies. The association of reported strategies with discharge antibiotic overuse (unnecessary, excess, suboptimal fluoroquinolones) for community-acquired pneumonia (CAP) and urinary tract infection (UTI) was evaluated in 2 ways: (1) all strategies assumed equal weight and (2) strategies were weighted based on the ROAD (Reducing Overuse of Antibiotics at Discharge) Home Framework (ie, Tier 1-Critical infrastructure, Tier 2-Broad inpatient interventions, Tier 3-Discharge-specific strategies) with Tier 3 strategies receiving the highest weight. RESULTS: Between 1 July 2017 and 30 July 2019, 39 hospitals with 20 444 patients (56.5% CAP; 43.5% UTI) were included. Survey response was 100%. Hospitals reported a median (interquartile range [IQR]) 12 (9-14) of 34 possible stewardship strategies. On analyses of individual stewardship strategies, the Tier 3 intervention, review of antibiotics prior to discharge, was the only strategy consistently associated with lower antibiotic overuse at discharge (adjusted incident rate ratio [aIRR] 0.543, 95% confidence interval [CI]: .335-.878). On multivariable analysis, weighting by ROAD Home tier predicted antibiotic overuse at discharge for both CAP and UTI. For diseases combined, having more weighted strategies was associated with lower antibiotic overuse at discharge (aIRR 0.957, 95% CI: .927-.987, per weighted intervention); discharge-specific stewardship strategies were associated with a 12.4% relative decrease in antibiotic overuse days at discharge. CONCLUSIONS: The more stewardship strategies a hospital reported, the lower its antibiotic overuse at discharge. However, Tier 3, or discharge-specific strategies, appeared to have the largest effect on antibiotic prescribing at discharge.

RESUMO

BACKGROUND: Longissimus muscle samples were collected from lambs exposed in utero to mycotoxins [E-, endophyte-free tall fescue seed without ergot alkaloids (negative control) or E + , endophyte-infected tall fescue seed containing ergot alkaloids] during mid-gestation (MID; E + /E-) or late-gestation (LATE; E-/E +) harvested at two developmental stages (FETAL, gestational d133) or (MAT, near maturity, 250 d of age; n = 3/treatment/developmental stage). Muscle samples were examined to determine the impact of in utero mycotoxin exposure on skeletal muscle fiber hypertrophy and the miRNA profile at FETAL and MAT. RESULTS: Longissimus weight was greater (P < 0.05) in E + /E- lambs compared to E-/E + lambs at MAT; however, FETAL longissimus weight did not differ (P > 0.10) between fescue treatments. Type I fiber cross sectional area was larger (P < 0.10) for E + /E- than E-/E + at MAT but did not differ (P > 0.10) between fescue treatments at FETAL. Type II fiber area was larger (P < 0.05) at MAT in E + /E- compared to E-/E + but did not differ (P < 0.05) between fescue treatments at FETAL. Cross-sectional Type I and Type II longissimus muscle fiber area increased (P < 0.05) from FETAL to MAT by 6.86-fold and 10.83-fold, respectively. The ratio of Type II:Type I muscle fibers was lower (P = 0.04) at MAT compared to FETAL. There were 120 miRNA differentially expressed (q < 0.05) between FETAL and MAT. Maternal fescue treatment did not alter (q > 0.05) expression of miRNAs in the longissimus muscle. miR-133, -29a, -22-3p, and -410-3p were identified as highly significant with a log2 fold change > 4. In vitro satellite cell cultures showed that selected miRNAs (miR-22-3p, 29a, 27a, and 133a) are differentially regulated during proliferation and differentiation indicating a role of miRNA in muscle hypertrophy. CONCLUSIONS: Exposure to mycotoxins did not alter fiber type but had long-term impacts on postnatal muscle hypertrophy and cross-sectional area. The miRNA profile of the longissimus was not altered by Maternal mycotoxin exposure at FETAL or MAT. Developmental age altered the miRNA transcriptome and mRNA expression of known genes related to muscle growth. These results indicate that Maternal exposure to E + fescue seed during LATE gestation can alter postnatal muscle hypertrophy in sheep; however, these changes are not regulated by the miRNA transcriptome of the longissimus muscle.

RESUMO

BACKGROUND: Healthcare-associated infection (HAI) is a common and largely preventable cause of morbidity and mortality. The COVID-19 pandemic has presented unprecedented challenges to health systems. We conducted a national survey to ascertain hospital characteristics and the use of HAI prevention measures in Israel. METHODS: We e-mailed surveys to infection prevention and control (IPC) leads of acute care hospitals in Israel. The survey included questions about the use of practices to prevent catheter-associated urinary tract infection (CAUTI), central line-associated bloodstream infection (CLABSI), ventilator-associated pneumonia (VAP), and Clostridioides difficile infection (CDI). The survey also assessed COVID-19 impact and healthcare worker well-being. RESULTS: IPC leads from 15 of 24 invited hospitals (63%) completed the survey. Only one-third of respondents reported strong support for IPC from hospital leadership. Although several prevention practices were used by all hospitals (e.g., maximum sterile barrier precautions for CLABSI and real-time assessment of environmental cleaning for CDI), use of other practices was suboptimal-particularly for CAUTI and VAP. COVID-19 had a profound impact on Israeli hospitals, with all hospitals reporting opening of new units to care for COVID patients and most reporting moderate to extreme financial hardship. All hospitals reported highly successful plans to vaccinate all staff and felt confident that the vaccine is safe and effective. CONCLUSION: We provide a status report of the IPC characteristics and practices Israeli hospitals are currently using to prevent HAIs during the COVID-19 era. While many globally accepted IPC practices are widely implemented, opportunities to increase the use of certain IPC practices in Israeli hospitals exist.

RESUMO

BACKGROUND: Copy number variations (CNV) are a significant source of variation in the genome and are therefore essential to the understanding of genetic characterization. The aim of this study was to develop a fine-scaled copy number variation map for African goats. We used sequence data from multiple breeds and from multiple African countries. RESULTS: A total of 253,553 CNV (244,876 deletions and 8677 duplications) were identified, corresponding to an overall average of 1393 CNV per animal. The mean CNV length was 3.3 kb, with a median of 1.3 kb. There was substantial differentiation between the populations for some CNV, suggestive of the effect of population-specific selective pressures. A total of 6231 global CNV regions (CNVR) were found across all animals, representing 59.2 Mb (2.4%) of the goat genome. About 1.6% of the CNVR were present in all 34 breeds and 28.7% were present in all 5 geographical areas across Africa, where animals had been sampled. The CNVR had genes that were highly enriched in important biological functions, molecular functions, and cellular components including retrograde endocannabinoid signaling, glutamatergic synapse and circadian entrainment. CONCLUSIONS: This study presents the first fine CNV map of African goat based on WGS data and adds to the growing body of knowledge on the genetic characterization of goats.

RESUMO

Assessment of potentially traumatic events and related psychological symptoms in refugee youth is common in epidemiological and intervention research. The objective of this study is to characterize reactions to assessments of trauma exposure and psychological symptoms, including traumatic stress, in refugee youth and their caregivers. Eighty-eight Somali youth and their caregivers participated in a screening and baseline interview for a psychological intervention in three refugee camps in Ethiopia. Participants were asked about their levels of distress prior to, immediately after, and approximately two weeks after completing the interview. Other quantitative and qualitative questions inquired about specific reactions to interview questions and procedures. Children and caregivers became increasingly relaxed over the course of the interview, on average. Few children (5.3%) or caregivers (6.5%) who reported being relaxed at the beginning of the interview became upset by the end of the interview. Some children and caregivers reported that certain assessment questions were upsetting and that feeling upset interfered with their activities. Despite some participants reporting persistent negative reactions, most reported liking and benefitting from the interview. While the majority of refugee youth and their caregivers reported positive experiences associated with completing trauma-related assessments, some reported negative reactions. Researchers and practitioners must consider the necessity, risks, and benefits of including questions about potentially traumatic events and related symptoms that are particularly upsetting in screening, survey research, and clinical assessment. When included, it is important that researchers and practitioners monitor negative reactions to these assessments and connect participants who become distressed with appropriate services.

RESUMO

Regulatory T cells (Tregs ) are specialized in immune suppression and play a dominant role in peripheral immune tolerance. Treg  cell lineage development and function maintenance is determined by the forkhead box protein 3 (FoxP3) transcriptional factor, whose activity is fine-tuned by its post-translational modifications (PTMs) and interaction partners. In this review, we summarize current studies in the crystal structures, the PTMs and interaction partners of FoxP3 protein, and discuss how these insights may provide a roadmap for new approaches to modulate Treg  suppression, and new therapies to enhance immune tolerance in autoimmune diseases.

RESUMO

For people living with HIV, lack of adherence to antiretroviral therapy (ART) is a serious problem and frequently results in HIV disease progression. Reasons for non-adherence include concomitant psychosocial health conditions - also known as syndemic conditions - such symptoms of depression or posttraumatic stress disorder (PTSD), past physical or sexual abuse, intimate partner violence (IPV), stimulant use, and binge drinking. The aim of this study was to investigate the association between syndemic conditions and medication adherence. The sample included 281 older men living with HIV who have sex with men (MSM). The study period was December 2012-July 2016. We observed the following syndemic conditions significantly decreased medication adherence: symptoms of depression (p = .008), PTSD (p = .002), and stimulant use (p < .0001). Past physical or sexual abuse, IPV, and binge drinking were not significantly associated with decreased medication adherence. The findings suggest that syndemic conditions may impact medication adherence in older MSM living with HIV.

RESUMO

BACKGROUND: Alcohol use is a consistent correlate of intimate partner violence (IPV) in low-income and middle-income countries (LMICs). However, the magnitude of this association differs across studies, which may be due to contextual and methodological factors. This study aims to estimate and explore sources of heterogeneity in the association between alcohol use and IPV in 28 LMICs (n=109 700 couples). METHODS: In nationally representative surveys, partnered women reported on IPV victimisation and male partner's alcohol use. We estimated the relationship between alcohol use and IPV using logistic regression and full propensity score matching to account for confounding. Country-specific ORs were combined using a random-effects model. Country-level indicators of health and development were regressed on ORs to examine sources of variability in these estimates. RESULTS: Partner alcohol use was associated with a 2.55-fold increase in the odds of past-year IPV victimisation (95% CI 2.27 to 2.86) with substantial variability between regions (I2=70.0%). Countries with a low (<50%) prevalence of past-year alcohol use among men displayed larger associations between alcohol use and IPV. Exploratory analyses revealed that colonisation history, religion, female literacy levels and substance use treatment availability may explain some of the remaining heterogeneity observed in the strength of the association between alcohol use and IPV across countries. CONCLUSION: Partner alcohol use is associated with increased odds of IPV victimisation in LMICs, but to varying degrees across countries. Prevalences of male alcohol use and cultural factors were related to heterogeneity in these estimates between countries.

RESUMO

Background: Central line-associated bloodstream infection (CLABSI) remains prevalent in hospitals in the United States. Objective: To evaluate the impact of a multimodal intervention in hospitals with elevated rates of health care-associated infection. Design: Pre-post observational evaluation of a prospective, national, clustered, nonrandomized initiative of 3 cohorts of hospitals. Setting: Acute care, long-term acute care, and critical access hospitals, including intensive care units and medical/surgical wards. Participants: Target hospitals had a cumulative attributable difference above the first tertile of performance for Clostridioides difficile infection and another health care-associated infection (such as CLABSI). Some hospitals that did not meet these criteria also participated. Intervention: A multimodal intervention consisting of recommendations and tools for prioritizing and implementing evidence-based infection prevention strategies, on-demand educational videos, webinars led by content experts, and access to content experts. Measurements: Rates of CLABSI and device utilization ratio pre- and postintervention. Results: Between November 2016 and May 2018, 387 hospitals in 23 states and the District of Columbia participated. Monthly preimplementation CLABSI rates ranged from 0 to 71.4 CLABSIs per 1000 catheter-days. Over the study period, the unadjusted CLABSI rate was low and decreased from 0.88 to 0.80 CLABSI per 1000 catheter-days. Between the pre- and postintervention periods, device utilization decreased from 24.05 to 22.07 central line-days per 100 patient-days. However, a decreasing trend in device utilization was also observed during the preintervention period. Limitations: The intervention period was brief. Participation in and adherence to recommended interventions were not fully assessed. Rates of CLABSI were low. Patient characteristics could not be assessed. Conclusion: In hospitals with a disproportionate burden of health care-associated infection, a multimodal intervention did not reduce rates of CLABSI.

RESUMO

Background: Many hospitals struggle to prevent catheter-associated urinary tract infection (CAUTI). Objective: To evaluate the effect of a multimodal initiative on CAUTI in hospitals with high burden of health care-associated infection (HAI). Design: Prospective, national, nonrandomized, clustered, externally facilitated, pre-post observational quality improvement initiative, for 3 cohorts active between November 2016 and May 2018. Setting: Acute care, long-term acute care, and critical access hospitals, including intensive care and non-intensive care wards. Participants: Target hospitals had a high burden of Clostridioides difficile infection plus central line-associated bloodstream infection, CAUTI, or hospital-onset methicillin-resistant Staphylococcus aureus bloodstream infection, defined as cumulative attributable differences above the first tertile in the Targeted Assessment for Prevention (TAP) strategy. Some additional nonrecruited hospitals also joined. Intervention: Multimodal intervention, including Practice Change Assessment tool to identify infection prevention and control (IPC) and HAI prevention gaps; Web-based, on-demand modules involving onboarding, foundational IPC practices, HAI-specific 2-tiered approach to prioritize and implement interventions, and TAP resources; monthly webinars; state partner-led in-person meetings; and feedback. State partners made site visits to at least 50% of their enrolled hospitals, to support self-assessments and coach. Measurements: Rates of CAUTI and urinary catheter device utilization ratio. Results: Of 387 participating hospitals from 23 states and the District of Columbia, 361 provided CAUTI data. Over the study period, the unadjusted CAUTI rate was low and relatively stable, decreasing slightly from 1.12 to 1.04 CAUTIs per 1000 catheter-days. Catheter utilization decreased from 21.46 to 19.83 catheter-days per 100 patient-days from the pre- to the postintervention period. Limitations: The intervention period was brief, with no assessment of fidelity. Baseline CAUTI rates were low. Patient characteristics were not assessed. Conclusion: This multimodal intervention yielded no substantial improvements in CAUTI or urinary catheter utilization. Primary Funding Source: Centers for Disease Control and Prevention.

RESUMO

Although the prevalence of substance use disorders (SUDs) is higher among men, women with SUDs in low- and middle-income countries (LMICs) face unique challenges. Poverty and adversity, inequality of women, and disparities in access to treatment and prevention services exacerbate biological, psychological and social correlates of substance use disorders for women living in low-resource settings. Increasing the inclusion of women in research has long been a goal, though even high income countries struggle to achieve parity. In LMICs, women with SUDs are often neglected from global research due to underreporting and the disproportionate focus of global substance use research on men. We will discuss risk factors for SUDs that are particularly relevant for women residing in LMICs in order to gain insight into neglected areas of research and opportunities for prevention and treatment.

RESUMO

BACKGROUND: Catheter-associated urinary tract infection (UTI) is a common device-associated infection in hospitals. Both technical factors--appropriate catheter use, aseptic insertion, and proper maintenance--and socioadaptive factors, such as cultural and behavioral changes in hospital units, are important in preventing catheter-associated UTI. METHODS: The national Comprehensive Unit-based Safety Program, funded by the Agency for Healthcare Research and Quality, aimed to reduce catheter-associated UTI in intensive care units (ICUs) and non-ICUs. The main program features were dissemination of information to sponsor organizations and hospitals, data collection, and guidance on key technical and socioadaptive factors in the prevention of catheter-associated UTI. Data on catheter use and catheter-associated UTI rates were collected during three phases: baseline (3 months), implementation (2 months), and sustainability (12 months). Multilevel negative binomial models were used to assess changes in catheter use and catheter-associated UTI rates. RESULTS: Data were obtained from 926 units (59.7% were non-ICUs, and 40.3% were ICUs) in 603 hospitals in 32 states, the District of Columbia, and Puerto Rico. The unadjusted catheter-associated UTI rate decreased overall from 2.82 to 2.19 infections per 1000 catheter-days. In an adjusted analysis, catheter-associated UTI rates decreased from 2.40 to 2.05 infections per 1000 catheter-days (incidence rate ratio, 0.86; 95% confidence interval [CI], 0.76 to 0.96; P=0.009). Among non-ICUs, catheter use decreased from 20.1% to 18.8% (incidence rate ratio, 0.93; 95% CI, 0.90 to 0.96; P<0.001) and catheter-associated UTI rates decreased from 2.28 to 1.54 infections per 1000 catheter-days (incidence rate ratio, 0.68; 95% CI, 0.56 to 0.82; P<0.001). Catheter use and catheter-associated UTI rates were largely unchanged in ICUs. Tests for heterogeneity (ICU vs. non-ICU) were significant for catheter use (P=0.004) and catheter-associated UTI rates (P=0.001). CONCLUSIONS: A national prevention program appears to reduce catheter use and catheter-associated UTI rates in non-ICUs. (Funded by the Agency for Healthcare Research and Quality.).

RESUMO

BACKGROUND: Hazardous alcohol use is a predictor of intimate partner violence (IPV), and both are increasingly prevalent in sub-Saharan Africa. The accurate measurement of alcohol consumption is therefore critical in IPV intervention studies that target hazardous drinking. Collecting a collateral report in addition to self-report is one convergent validity approach to improve alcohol measurement. We investigated concordance between self- and partner-reported alcohol use among women who reported recent IPV and their male partners in Zambia. METHODS: Data were from the baseline of a randomized IPV intervention trial of 247 heterosexual couples in which a woman has reported recent IPV and her male partner has recent hazardous alcohol use. Both partners completed the Alcohol Use Disorders Identification Test (AUDIT) in reference to their own drinking and in reference to their partner's drinking. We calculated percent agreement across a range of outcomes: any use, quantity, frequency, and hazardous use. We also compared self- and partner-reported AUDIT scores using t-tests. RESULTS: Concordance was poor across most outcomes. Percent agreement with respect to the women's drinking ranged from 60% to 65% across outcomes and with respect to the men's drinking from 51% to 89%. Women's average partner-reported AUDIT score (20.7) was statistically significantly (p < 0.0001) higher than men's average self-reported score (15.8). CONCLUSIONS: In contrast to collateral report studies conducted in the United States, concordance between self- and partner-reported alcohol consumption was poor among families experiencing IPV in Zambia. Given the possible biases associated with self-reported alcohol use, findings suggest that a convergent validity approach is useful in this research context.

RESUMO

BACKGROUND AND PURPOSE: Research indicates that patients with myotonic dystrophy type 1 (DM1) are at increased risk of cancer and early death. Family data may provide insights given DM1 phenotypic heterogeneity, the broad range of non-muscular manifestations and the usual delays in the diagnosis of DM1. METHOD: Family history data were collected from 397 genetically and/or clinically confirmed DM1 patients (respondents) enrolled in the US or UK myotonic dystrophy registries. Standardized mortality ratios were calculated for DM1 first-degree relatives (parents, siblings and offspring) by their reported DM1 status (affected, unaffected or unknown). For cancer-related analyses, mixed effects logistic regression models were used to evaluate factors associated with cancer development in DM1 families, including familial clustering. RESULTS: A total of 467 deaths and 337 cancers were reported amongst 1737 first-degree DM1 relatives. Mortality risk amongst relatives reported as DM1-unaffected was comparable to that of the general population [standardized mortality ratio (SMR) 0.82, P = 0.06], whilst significantly higher mortality risks were noted in DM1-affected relatives (SMR = 2.47, P < 0.0001) and in those whose DM1 status was unknown (SMR = 1.60, P < 0.0001). In cancer risk analyses, risk was higher amongst families in which the DM1 respondent had cancer (odds ratio 1.95, P = 0.0001). Unknown DM1 status in the siblings (odds ratio 2.59, P = 0.004) was associated with higher cancer risk. CONCLUSION: There is an increased risk of death, and probably cancer, in relatives with DM1 and in those whose DM1 status is unknown. This suggests a need to perform a careful history and physical examination, supplemented by genetic testing, to identify family members at risk for DM1 and who might benefit from disease-specific clinical care and surveillance.

RESUMO

AIMS: To evaluate theory-based psychological approaches that have been effective in promoting behavior change in interventions promoting a Mediterranean style diet (MD) for the reduction of cardiovascular disease (CVD) risk. DATA SYNTHESIS: A systematic review of primary research articles using PRISMA recommendations was conducted. References were retrieved using keyword searches from MEDLINE via PUBMED and included studies targeted participants at high risk for CVD. Two hundred and ninety one studies were reviewed; however, only six met the inclusionary criteria. Three articles describe the same intervention; therefore, only four were included. Included studies incorporated social cognitive theory, social learning theory, goal-system theory, social ecological theory, selfdetermination theory, and the transtheoretical model of behavior change. Overall, studies were nutrition interventions in clinical settings with participants at high risk for or with CVD. CONCLUSIONS: Results from use of the social cognitive theory and self-determination theory in increasing MD adherence for the reduction of CVD risk and events are encouraging. However, we encourage future long-term interventions focusing on dietary behavior change to provide not only an in-depth description of the psychological methodologies used but also how these methodologies were implemented in order ascertain the most effective theory for promoting dietary behavior change towards patterns of a MD.
