RESUMO

INTRODUCTION AND HYPOTHESIS: The aim was to assess the association between the degree of physical activity (PA) and the presence of pelvic floor disorders (PFDs) in a cohort of parous Ugandan women. METHODS: In this cross-sectional study, PFDs were measured using symptom assessment, standardized questionnaires (Pelvic Floor Distress Inventory and Pelvic Floor Impact Questionnaire), and a standardized physical examination (POP-Q and cough stress test [CST]). Degree of PA was assessed using the International Physical Activity Questionnaire. Interquartile ranges were used to describe the age, parity, and body mass index (BMI) of participants. To examine the association between PA and PFDs, a log transformation was applied to the weekly minutes of PA variable and a logistic regression model was constructed with weekly minutes of moderate/vigorous PA, age, BMI, and parity as the predictors. RESULTS: A total of 159 women were enrolled. Median age was 35 (IQR 32-37), median parity 4 (IQR 3-5), and median BMI 29.0 (IQR 24-33). The prevalence of PFD as determined by symptom assessment was 28% (n=44). The most frequent stage of prolapse identified by POP-Q was stage II (57%, n=91). Thirty-six percent of the women (n=58) reported vigorous PA. Ninety-nine percent of the cohort (n=158) reported moderate PA. When controlling for age, parity, and BMI there was a significant positive association between PFD (defined as a combination of stage II prolapse, positive CST, and urinary incontinence (UI)) and moderate PA (OR 2.20, 95% CI 1.08-5.14, p value 0.045). CONCLUSIONS: Pelvic floor disorders are common among parous Ugandan women and are associated with moderate PA when controlling for age, BMI, and parity. Understanding the risk factors associated with PFD in this population may better equip providers to screen and care for individuals.

RESUMO

INTRODUCTION AND HYPOTHESIS: Pelvic floor disorders (PFDs) impact women worldwide and are assessed using instruments such as the Pelvic Floor Distress Inventory (PFDI-20) and Pelvic Floor Impact Questionnaire (PFIQ-7). There are no known valid PFD instruments in Uganda. This study's purpose was to translate and test the reliability and validity of the PFDI-20 and PFIQ-7 in Luganda. It was predicted that these instruments would be reliable and valid to assess the presence and impact of PFD in parous Luganda-speaking women. METHODS: The translated PFDI-20 and PFIQ-7 were administered to parous Luganda-speaking women and readministered 4-8 months after. The Pelvic Organ Prolapse Quantification (POP-Q) examination determined the presence of pelvic organ prolapse (POP) and a cough-stress test (CST) measured urinary leakage. Analysis was completed using Cronbach's α co-efficient for internal consistency and Spearman's correlation coefficients and Wilcoxon rank sum tests for construct validity. RESULTS: Of the 159 participants, 93 (58.3%) had stage II POP or higher. The PFDI-20 and PFIQ-7 demonstrated minimal bother and impact on activities of daily living respectively. The Urinary Distress Inventory 6 (UDI-6) scores on the PFDI-20 showed a strong positive association with the presence of urinary incontinence. When PFD was defined by responses to symptom assessment, the translated PFDI-20 and PFIQ-7 could differentiate between individuals with and without PFD. CONCLUSIONS: The UDI-6 section of the PFDI-20 was found to be valid in Luganda. The PFIQ-7 and the entirety of the PFDI-20 were not found to be reliable or valid, likely because of the low prevalence of PFDs in the study population.

RESUMO

Standard methods for the evaluation of recreational water quality rely on generic bacterial indicators such as . However, does not provide enough information to determine fecal source or public health risk. The stsudy objective was to determine factors influencing the presence of and host-specific markers (HSM) from upstream to downstream in Beaver Lake Reservoir (BLR). From February 2014 to September 2015, 420 base flow and rain event samples were collected from seven sites-two sites from streams (White River [WR] and War Eagle Creek) draining into BLR and five sites from within BLR. Each sample was analyzed for and by quantitative polymerase chain reaction for HSM related to human, bovine, and poultry. The data indicate that overall levels of were significantly greater in the WR and significantly lower at the most downstream sampling location in BLR. is more likely present during spring (adjusted odds ratio [aOR] = 1.86), at the WR sampling site (aOR = 3.39), or during a rain event (aOR = 2.73). Moreover, the HSM HumM2 is more likely present (aOR = 1.99) when is present. These same factors were associated with concentrations >126 most probable number 100 mL (aOR = 2.76-12.48), except the poultry marker CL was more likely associated (aOR = 3.81) than HumM2. This study revealed that both seasonal and locational factors are important variables for fecal pollution in BLR. Moreover, these same factors may apply to fecal pollution in manmade reservoirs within similar types of watersheds across the United States, as well as internationally.

RESUMO

DUF1220 domains show the largest human-lineage-specific increase in copy number of any protein-coding region in the human genome and map primarily to 1q21, where deletions and reciprocal duplications have been associated with microcephaly and macrocephaly, respectively. Given these findings and the high correlation between DUF1220 copy number and brain size across primate lineages (R(2) = 0.98; p = 1.8 × 10(-6)), DUF1220 sequences represent plausible candidates for underlying 1q21-associated brain-size pathologies. To investigate this possibility, we used specialized bioinformatics tools developed for scoring highly duplicated DUF1220 sequences to implement targeted 1q21 array comparative genomic hybridization on individuals (n = 42) with 1q21-associated microcephaly and macrocephaly. We show that of all the 1q21 genes examined (n = 53), DUF1220 copy number shows the strongest association with brain size among individuals with 1q21-associated microcephaly, particularly with respect to the three evolutionarily conserved DUF1220 clades CON1(p = 0.0079), CON2 (p = 0.0134), and CON3 (p = 0.0116). Interestingly, all 1q21 DUF1220-encoding genes belonging to the NBPF family show significant correlations with frontal-occipital-circumference Z scores in the deletion group. In a similar survey of a nondisease population, we show that DUF1220 copy number exhibits the strongest correlation with brain gray-matter volume (CON1, p = 0.0246; and CON2, p = 0.0334). Notably, only DUF1220 sequences are consistently significant in both disease and nondisease populations. Taken together, these data strongly implicate the loss of DUF1220 copy number in the etiology of 1q21-associated microcephaly and support the view that DUF1220 domains function as general effectors of evolutionary, pathological, and normal variation in brain size.

RESUMO

Glycoproteins secreted into plasma from T cells infected with human immunodeficiency virus (HIV) latent infection may provide insight into understanding the host response to HIV infection in vivo. Glycoproteomics, which evaluates the level of the glycoproteome, remains a novel approach to study this host response to HIV. In order to identify human glycoproteins secreted from T cells with latent HIV infection, the medium from cultured HIV replication-competent T cells was compared with the medium from cultured parental A3.01 cells via solid phase extraction of glycopeptides (SPEG) and high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). Using these methods, 59 human glycoproteins were identified as having significantly different abundance levels between the media from these two cell lines. The relevance of these 59 proteins to HIV infection in vivo was assessed in plasma from HIV+ and HIV- subjects. Comparison between T cell and plasma revealed that six glycoproteins (galectin-3-binding protein, L-selectin, neogenin, adenosine deaminase CECR1, ICOS ligand and phospholipid transfer protein) were significantly elevated in the HIV+ T cells and plasma studies. These findings suggest that the response of T cells harboring latent HIV infection contributed, in part, to the glycoprotein changes in HIV+ plasma. These proteins, once validated, could provide insight into host-HIV interaction.

RESUMO

Background: It was to understand HPV vaccination patterns, uptake, perceptions, and sexual risk factors in students at a Midwest public university. Participants: Students were enrolled during the spring 2024 semester at the University of Iowa. Methods: A survey was developed and emailed to 28,095 students asking demographic, general and sexual health, and HPV-related questions. Results: The response rate was 4.9%, with 76% females and a median age of 22. The HPV vaccine uptake was 82%, with 88% recommending the vaccine. Parental preference was the main reason for being unvaccinated. The median age of sexual debut was 17 years, with a median of 2 sexual partners. Vaccination was associated with female, health science, sexually active, and COVID-19/influenza vaccinated students. Conclusions: HPV vaccine uptake at University of Iowa students is higher than the national and Iowa averages. Increased education regarding HPV vaccination is still needed, particularly in males, those not having sex, and those not receiving other vaccines.

RESUMO

OBJECTIVES: The aim of this study was to determine the prevalence of pelvic floor disorders (PFDs) and associated risk factors among parous Ugandan women. METHODS: We performed a cross-sectional study of parous Ugandan women. Demographics and assessment for PFD were obtained. The presence of PFD was defined by participant symptom report, standardized questionnaires, and standard physical examination (pelvic organ prolapse quantification [POP-Q] and cough stress test [CST]). RESULTS: A total of 159 women were enrolled in the study between June 2022 and June 2023. The median age was 35 years and median parity was 4. Forty-four (28%) women in the cohort reported symptoms of urinary incontinence. No women reported symptoms of pelvic organ prolapse or anal incontinence. Seventy-two (46%) participants had a positive CST and 93 (58.3%) had stage II or greater prolapse based on the POP-Q. Cesarean section was found to have a protective effect for the development of PFD (odds ratio [OR] 0.22, 95% confidence interval [CI] 0.07-0.59, P = 0.004). CONCLUSION: PFDs are prevalent among parous Ugandan women at rates similar to cohorts in other low- and middle-income countries. Cesarean section seems to be a protective factor against developing PFDs.

RESUMO

BACKGROUND: The high case-fatality rates among children with tuberculosis (TB) are reportedly driven by in-hospital mortality and severe forms of TB. Therefore, there is need to better understand the predictors of mortality among children hospitalised with TB. We examined the patient clinical profiles, length of hospital stay from date of admission to date of final admission outcome, and predictors of mortality among children hospitalised with TB at two tertiary hospitals in Uganda. METHODS: We conducted a case-series study of children below 15 years of age hospitalised with TB, from January 1st, 2016, to December 31st, 2021. Convenience sampling was done to select TB cases from paper-based medical records at Mulago National Referral Hospital (MNRH) in urban Kampala, and Fort Portal Regional Referral Hospital (FRRH) in rural Fort Portal. We fitted linear and logistic regression models with length of stay and in-hospital mortality as key outcomes. RESULTS: Out of the 201 children hospitalised with TB, 50 were at FRRH, and 151 at MNRH. The male to female ratio was 1.5 with median age of 2.6 years (Interquartile range-IQR 1-6). There was a high prevalence of HIV (67/171, 39%), severe malnutrition reported as weight-for-age Z-score <-3SD (51/168, 30%). Among children with pulmonary TB who initiated anti-tuberculosis therapy (ATT) either during hospitalisation or within seven days prior to hospitalisation; cough (134/143, 94%), fever (111/143, 78%), and dyspnoea (78/143, 55%) were common symptoms. Children with TB meningitis commonly presented with fever (17/24, 71%), convulsions (14/24 58%), and cough (13/24, 54%). The median length of hospital stay was 8 days (IQR 5-15). Of the 199 children with known in-hospital outcomes, 34 (17.1%) died during hospitalisation. TB meningitis was associated with in-hospital mortality (aOR = 3.50, 95% CI = 1.10-11.17, p = 0.035), while male sex was associated with reduced mortality (aOR = 0.33, 95% CI = 0.12-0.95, p = 0.035). Hospitalisation in the urban hospital predicted a 0.48-day increase in natural log-transformed length of hospital stay (ln-length of stay) (95% CI 0.15-0.82, p = 0.005), but not age, sex, HIV, malnutrition, or TB meningitis. CONCLUSIONS: In-hospital mortality was high, and significantly driven almost four times higher by TB meningitis, with longer hospital stay among children in urban hospitals. The high in-hospital mortality and long hospital stay may be reduced by timely TB diagnosis and treatment initiation among children.

RESUMO

More than 50 red blood cell (RBC) alloantibodies are known to cause hemolytic disease of the fetus and newborn (HDFN).Although Rh immune globulin (RhiG) prophylaxis has significantly reduced the incidence of pregnancies complicated by anti-D, the need to detect and monitor maternal allo antibodies capable of causing HDFN is still a concern. The prevalence and specificity of these alloantibodies were determined. In this retrospective study, the prevalence and specificities of unexpected RBC alloantibodies known to cause HDFN in pregnant women at a tertiary-care facility during a 5-year period were compiled and analyzed. Patient selection was carried out by computerized search of patient data based on an obstetric location and the presence or history of RBC antibody between January 1, 2007,and December 31, 2011. The information was organized by ABO and D status of the patient, antibody specificity, and transfusion needs. Of the 8894 obstetric patients identified during the 5-year period, 264 (3.0%) had one or more unexpected RBC antibodies.Of these 264 women, 107 (40.5%), or 1.2 percent overall, had an alloantibody known to cause HDFN, with a total of 15 different alloantibodies identified. The most common alloantibody found was anti-E (n = 33), followed by anti-M (n = 26) and anti-D (n= 20). In pregnancies of D- women, the most common clinically significant antibodies found were anti-D (n = 20), anti-C (n = 11),and anti-E (n = 2). In pregnancies of D+ women, the most common antibodies were anti-E (n = 31), anti-M (n = 25), and anti-K (n= 16). A total of eight pregnancies with alloantibodies required intrauterine transfusions with the specificities of anti-D; anti-D,-C(n = 2); anti-D,-C,-E; anti-D,-C,-K; anti-D,-C,-Jkb; anti-D,-S; and anti-E,-c. At a large academic tertiary-care center, approximately 1 in 83 obstetric patients had one or more RBC alloantibodies capable of causing HDFN. Anti-E, -M, and -D were the most frequent specificities, respectively.

RESUMO

People generally have better memories for traits that are stereotypic consistent rather than stereotypic inconsistent. From social identity theory, we hypothesized that this stereotype consistency effect would be moderated by group membership and trait valence. Specifically, we expected the typical stereotype-consistency effect when the target person was an outgroup member (different ethnicity from the participant). However, if the target person was an ingroup member (same ethnicity as the participant), we expected stereotypicality to facilitate memory for positive traits but not negative traits. Participants (N = 104) read a series of statements about an ingroup member or an outgroup member and subsequently completed a memory test. The results confirmed our main prediction. The findings have implications for social identity theory, social cognition research, and for understanding intergroup relations.

RESUMO

Little is known about how genetic variation at the nucleotide level contributes to competitive fitness within species. During a 6,000-generation study of Bacillus subtilis evolved under relaxed selection for sporulation, a new strain, designated WN716, emerged with significantly different colony and cell morphologies; loss of sporulation, competence, acetoin production, and motility; multiple auxotrophies; and increased competitive fitness (H. Maughan and W. L. Nicholson, Appl. Environ. Microbiol. 77:4105-4118, 2011). The genome of WN716 was analyzed by OpGen optical mapping, whole-genome 454 pyrosequencing, and the CLC Genomics Workbench. No large chromosomal rearrangements were found; however, 34 single-nucleotide polymorphisms (SNPs) and +1 frameshifts were identified in WN716 that resulted in amino acid changes in coding sequences of annotated genes, and 11 SNPs were located in intergenic regions. Several classes of genes were affected, including biosynthetic pathways, sporulation, competence, and DNA repair. In several cases, attempts were made to link observed phenotypes of WN716 with the discovered mutations, with various degrees of success. For example, a +1 frameshift was identified at codon 13 of sigW, the product of which (SigW) controls a regulon of genes involved in resistance to bacteriocins and membrane-damaging antibiotics. Consistent with this finding, WN716 exhibited sensitivity to fosfomycin and to a bacteriocin produced by B. subtilis subsp. spizizenii and exhibited downregulation of SigW-dependent genes on a transcriptional microarray, consistent with WN716 carrying a knockout of sigW. The results suggest that propagation of B. subtilis for less than 2,000 generations in a nutrient-rich environment where sporulation is suppressed led to rapid initiation of genomic erosion.

RESUMO

BACKGROUND AND PURPOSE: Pharmacy schools must have a framework to ensure students have the necessary knowledge, skills, attitudes, and behaviors to be successful during advanced pharmacy practice experiences (APPEs). EDUCATIONAL ACTIVITY AND SETTING: Ten summative assessments, called APPE-readiness assessments (ARAs), were developed based on eight competencies encompassing skills, behaviors, and attitudes that must be demonstrated prior to APPEs. All eight competencies were assessed in the course Case Studies in Pharmacotherapy IV, which is offered in the final semester of the didactic curriculum immediately prior to APPEs. A 15-question pre- and post-survey was conducted to assess student confidence in performing each APPE-readiness competency. Cohort data was evaluated by the curriculum and assessment committee to assess curriculum effectiveness and areas for improvement. FINDINGS: Upon completion of the course, the average first-attempt pass rate across all ARAs was 92.4%. All students who failed on the first attempt passed on the second attempt, thereby demonstrating APPE-readiness. Out of 62 students, 45 and 44 completed the pre- and post-survey, respectively. Prior to the ARAs, the overall average of students who felt (strongly) confident about their ability to perform each competency was 82.2 ± 2.1%. This increased to 92.6 ± 1.6% after the ARAs. SUMMARY: The development of an APPE-readiness assessment plan focusing on skills, attitudes, and behaviors provides insight into student and cohort performance and allows for continuous quality assurance of the pre-APPE curriculum.

RESUMO

We tested a mediation model of weight bias that considers person attributes and contact experiences with overweight individuals. In Study 1, we administered a survey to assess Openness, Agreeableness, Attributional Complexity, contact experiences with overweight individuals, and weight bias. Mediation analyses found that Agreeableness predicted less weight bias through contact experiences. In Study 2, we asked participants to interact with a peer whose weight and attributions regarding the weight were experimentally manipulated. We then measured acceptance of the peer. Agreeableness was found to indirectly predict more acceptance of an overweight peer through Empathy and contact experiences. These results show that contact theory is applicable to the domain of weight bias, and support person-situation approaches to prejudice.

RESUMO

BACKGROUND: The development of a safe and effective vaccine against HIV type 1 for the prevention of mother-to-child transmission of HIV would significantly advance the goal of eliminating HIV infection in children. Safety and feasibility results from phase 1, randomized, double-blind, placebo-controlled trial of ALVAC-HIV vCP1521 in infants born to HIV type 1-infected women in Uganda are reported. METHODS: HIV-exposed infants were enrolled at birth and randomized (4:1) to receive vaccine or saline placebo intramuscular injections at birth, 4, 8, and 12 weeks of age. Vaccine reactogenicity was assessed at vaccination and days 1 and 2 postvaccination. Infants were followed until 24 months of age. HIV infection status was determined by HIV DNA polymerase chain reaction. RESULTS: From October 2006 to May 2007, 60 infants (48 vaccine and 12 placebo) were enrolled with 98% retention at 24 months. One infant was withdrawn, but there were no missed visits or vaccinations among the 59 infants retained. Immune responses elicited by diphtheria, polio, hepatitis B, haemophilus influenzae type B, and measles vaccination were similar in the 2 arms. The vaccine was well tolerated with no severe or life-threatening reactogenicity events. Adverse events were equally distributed across both study arms. Four infants were diagnosed as HIV infected [3 at birth (2 vaccine and 1 placebo) and 1 in vaccine arm at 2 weeks of age]. CONCLUSION: The ALVAC-HIV vCP1521 vaccination was feasible and safe in infants born to HIV-infected women in Uganda. The conduct of high-quality infant HIV vaccine trials is achievable in Africa.

RESUMO

BACKGROUND: Decreased numbers of Langerhans cells (LCs) in the cervix of human immunodeficiency virus (HIV)-infected women are believed to contribute to the progression of human papilloma virus (HPV)-related squamous intraepithelial lesions. However, this impairment of local immunity has not been well studied in the vulva. The objective of this study was to compare the S100+ LC density in high-grade vulvar intraepithelial neoplasia (VIN) in HIV-positive and HIV-negative women. METHODS: HIV-positive and HIV-negative patients with high-grade VIN, 48 (55%) and 40 (45%), respectively, were identified by retrospective chart review. Smoking status of patients was noted. The mean LC count per high-power field (HPF) was determined using S100 immunohistochemical staining. In situ hybridization was performed to detect HPV DNA types 16 and 18. RESULTS: Mean S100+ LC counts for HIV-positive and HIV-negative patients were 5.82 and 9.86 per HPF, respectively (p = 0.0026). LC counts in HIV-positive and HIV-negative patients were compared between smoking and nonsmoking groups (HIV-positive p = 0.4812, HIV-negative p = 0.2821). CONCLUSIONS: HIV-positive patients with high-grade VIN had significantly lower LC counts compared with HIV-negative patients. This suggests that local vulvar immunity as evaluated by S100+ LCs is impaired in HIV-positive women, possibly contributing to the progression of HPV-related vulvar lesions.
