Nuestra Recuperación [Our Recovery]: using photovoice to understand the factors that influence recovery in Latinx populations.

BACKGROUND: Photovoice is a form of visual ethnography intended to engage impacted communities in research followed by action to ameliorate the injustices under study. Photovoice has increased in use, especially in collaboration with Latinx communities addressing health inequities. The Latinx population comprises nearly 18% of the overall United States population and according to the census is projected to reach just under 30% by 2060. This diverse panethnic community faces significant structural barriers in accessing services. Racism and the resulting marginalization, specifically, contributes to limited access to recovery services and treatment. Making meaningful advances in substance use disorder training, intervention and policy necessitates learning alongside the Latinx community. METHODS: We partnered with a Latinx serving integrated behavioral health and primary care setting in Boston Massachusetts to explore barriers and facilitators to recovery using photovoice. Spanish-speaking Latinx adults with a substance use disorder participated. The group met for three photovoice sessions over a six-week period. Together group members critically analyzed photographs using the SHOWeD method. RESULTS: Findings indicate a sense of purpose and meaning, security, faith and housing are important elements of recovery. The results illustrated the importance of sources of connection in maintaining sobriety. Through this photovoice project, Latinx Spanish speaking participants highlighted barriers and facilitators to their substance use disorder recovery which spanned individual, community, and structural levels. CONCLUSIONS: The experiences and voices of the Latinx community are crucial to drive discussions that advance policy (e.g., housing stability and access), enhance providers' understanding of Latinx Spanish-speakers' substance use disorder recovery, and inform culturally and linguistically appropriate services. This study demonstrated that photovoice is highly acceptable and feasible among Latinx clients receiving substance use disorder services. Visual images related to housing, faith, etc. communicate challenges, power structures, as well as hopes to policymakers at multiple levels (e.g., institution/ agency, state).

Medical care and treatment of children with asthmatic or wheezing health outcomes and urban-rural differences in Bavaria - a cross-sectional study.

Introduction: Asthma is among the most common chronic conditions in children. The aim of this publication is to describe prevalence rates and factors associated with asthmatic or wheezing preschoolers and to evaluate medical care and treatment with regard to urban-rural differences.Methods: Data for this cross-sectional study were collected through a questionnaire, which was distributed to parents within the Health Monitoring Units in Bavaria (HMU), Germany. Data from 4767 children were available (2016/17). Those children were classified into four diagnostic groups: Unremitting Wheeze, International Study of Asthma and Allergies in Children (ISAAC) Asthma, Physician-diagnosed Asthma, and healthy control group. Urban-rural differences were tested by Pearson's chi-squared test or by Fisher's exact test. Independent variables were factors associated with health outcomes, for example, residency or migrant status. To examine associations between independent and outcome variables multivariate logistic regression analysis was performed.Results: Prevalence rates were 6.3% for 'Unremitting Wheeze', 5.2% for 'ISAAC Asthma', and 1.2% for 'Physician-diagnosed Asthma'. Factors associated with health outcomes were the occurrence of asthma in first-degree relatives, male sex, and migrant status. Generally, higher rates of doctor's visits, positive allergy tests, and corticosteroids intake in the diagnostic groups in rural compared to urban areas were observed. Rates of performed allergy tests were 55.6% for 'ISAAC Asthma' and 74.6% for 'Physician-diagnosed Asthma'.Conclusions: Prevalence rates of the diagnostic groups decreased compared to the HMU 2014/15. According to previous studies, factors associated with asthmatic or wheezing health outcomes could be confirmed. Children in rural areas generally received more medical care.Key pointsChildren's prevalence rates of asthma or wheezing disorders decreased in the past 2 years within Bavaria.This study is consistent with risk factors for asthma from the literature: asthma in the family, male gender, and migrant status.Children in rural areas receive more medical care than children in urban areas.There should me more allergy tests among children with medical diagnosis in Bavaria as low rates indicate gaps in care.

Identification and characterization of miRNAs and lncRNAs of coho salmon (Oncorhynchus kisutch) in normal immune organs.

MicroRNAs (miRNAs) and long noncoding RNAs (lncRNAs) are two relevant non-coding RNAs (ncRNAs) class. Oncorhynchus kisutch (coho salmon) is an important aquaculture pacific salmon species without report of miRNAs and a very limited register of lncRNAs. To gain knowledge about the interaction and discovery of miRNAs and lncRNAs in coho salmon we used high-throughput sequencing technology to sequence small and transcriptome libraries from three immune organs. A total of 163 mature miRNAs and 4,975 lncRNAs were discovered. The profiles of expression of both ncRNAs indicated that liver and head-kidney share relatively similar expression patterns. We identified 814 and 181 putative target sequences for 1048 lncRNAs and 47 miRNAs, respectively. The results obtained provide new information and enlarge our understanding of the diversities of ncRNAs in coho salmon.

Helminth-derived molecules improve 5-fluorouracil treatment on experimental colon tumorigenesis.

Colorectal cancer (CRC) is one of the most prevalent fatal neoplasias worldwide. Despite efforts to improve the early diagnosis of CRC, the mortality rate of patients is still nearly 50%. The primary treatment strategy for CRC is surgery, which may be accompanied by chemotherapy and radiotherapy. The conventional and first-line chemotherapeutic agent utilized is 5-fluorouracil (5FU). However, it has low efficiency. Combination treatment with leucovorin and oxaliplatin or irinotecan improves the effectiveness of 5FU therapy. Unfortunately, most patients develop drug resistance, leading to disease progression. Here, we evaluated the effect of a potential alternative adjuvant treatment for 5FU, helminth-derived Taenia crassiceps (TcES) molecules, on treating advanced colitis-associated colon cancer. The use of TcES enhanced the effects of 5FU on established colonic tumors by downregulating the expression of the immunoregulatory cytokines, Il-10 and Tgf-ß, and proinflammatory cytokines, Tnf-α and Il-17a, and reducing the levels of molecular markers associated with malignancy, cyclin D1, and Ki67, both involved in apoptosis inhibition and the signaling pathway of ß-catenin. TcES+5FU therapy promoted NK cell recruitment and the release of Granzyme B1 at the tumor site, consequently inducing tumor cell death. Additionally, it restored P53 activity which relates to decreased Mdm2 expression. In vitro assays with human colon cancer cell lines showed that therapy with TcES+5FU significantly reduced cell proliferation and migration by modulating the P53 and P21 signaling pathways. Our findings demonstrate, for the first time in vivo, that helminth-derived excreted/secreted products may potentiate the effect of 5FU on established colon tumors.

Intranasal Versus Intravenous Dexamethasone to Treat Hospitalized COVID-19 Patients: A Randomized Multicenter Clinical Trial.

BACKGROUND: SARS-CoV2 induces flu-like symptoms that can rapidly progress to severe acute lung injury and even death. The virus also invades the central nervous system (CNS), causing neuroinflammation and death from central failure. Intravenous (IV) or oral dexamethasone (DXM) reduced 28 d mortality in patients who required supplemental oxygen compared to those who received conventional care alone. Through these routes, DMX fails to reach therapeutic levels in the CNS. In contrast, the intranasal (IN) route produces therapeutic levels of DXM in the CNS, even at low doses, with similar systemic bioavailability. AIMS: To compare IN vs. IV DXM treatment in hospitalized patients with COVID-19. METHODS: A controlled, multicenter, open-label trial. Patients with COVID-19 (69) were randomly assigned to receive IN-DXM (0.12 mg/kg for three days, followed by 0.6 mg/kg for up to seven days) or IV-DXM (6 mg/d for 10 d). The primary outcome was clinical improvement, as defined by the National Early Warning Score (NEWS) ordinal scale. The secondary outcome was death at 28 d between IV and IN patients. Effects of both treatments on biochemical and immunoinflammatory profiles were also recorded. RESULTS: Initially, no significant differences in clinical severity, biometrics, and immunoinflammatory parameters were found between both groups. The NEWS-2 score was reduced, in 23 IN-DXM treated patients, with no significant variations in the 46 IV-DXM treated ones. Ten IV-DXM-treated patients and only one IN-DXM patient died. CONCLUSIONS: IN-DMX reduced NEWS-2 and mortality more efficiently than IV-DXM, suggesting that IN is a more efficient route of DXM administration.

The Process of Developing a Digital Repository for Online Teaching Using Design-Based Research.

The Purdue Repository for Online Teaching and Learning (PoRTAL) was developed as an Open Educational Resource (OER) for graduate students and faculty in higher education settings to enhance their online teaching skills and strategies. The PoRTAL team used a design-based research approach (DBR; Wang & Hannafin, Educational Technology Research and Development, 53(4), 5-23, 2005). In this study context, we used Van Tiem et al.'s (2012) model to identify problems faced by instructors who struggled with or were new to online teaching from a Human Performance Technology (HPT) standpoint. To address the identified needs, we created resources for online teaching and embedded our research within practical activities to further study our design process. Our efforts resulted in an HPT-OER Model for Designing Digital Repositories. The purpose of this paper is to share the DBR process that we used to develop an OER repository within an HPT model.

Development and validation of the help-seeking intention scale in university students with hazardous and harmful consumption of alcohol.

Introduction: The Theory of Planned Behavior (TPB) has been proposed as suitable to study help-seeking intentions. This paper aims to develop the IH-RHAC scale (Help-seeking intention in young adults with hazardous and harmful alcohol consumption) with the TPB. The objectives of the study were: (a) to analyze the structure, reliability, and validity of the instrument, (b) to identify whether attitude, subjective norm, self-efficacy, and past help-seeking would predict help-seeking intention, and (c) to assess concurrent validity. Methods: From a total of 2,011 students who responded to the surveys, the sample was made up of 263 university students aged 18 to 29 with hazardous and harmful alcohol consumption practices, who responded to an online questionnaire including the AUDIT, IH-RHAC, and a scale of barriers and resources for alcohol consumption. Partial least squares structural equations (PLS-SEM) were used to test the hypotheses about reliability, validity of the scales, and prediction of the constructs: attitude, subjective norms, self-efficacy, and help-seeking in the past about intention. Pearson's correlations were used to obtain evidence of concurrent validity. Results: The results displayed favorable psychometric characteristics. The internal measurement model showed that attitude, self-efficacy, and prior help-seeking predicted a 27% help-seeking variance. Subjective norm did not predict intention. Discussion: It has been concluded that this is an instrument with psychometric support that can contribute to designing and/or evaluating interventions that promote the students' search for help.

Health-care policies during the COVID-19 pandemic in Mexico: A continuous case of heterogeneous, reactive, and unequal response.

Background: The pandemic in Mexico underlined pre-existing health-care system inequalities. Within the first six months of the COVID-19 pandemic, 154 health policies across health institutions were found to be uncoordinated and heterogeneous, leading to health inequalities in access and potential health outcomes. Data & methods: Using a rapid qualitative research methodology, data was collected using purposive sampling of institutional policies published for public access on the official websites of the four public health institutions in Mexico from June 16th, 2020 to October 30th, 2021. This policy review used archival analysis to understand the differences in health-care policies during the COVID-19 pandemic in Mexico. These policies were classified under the RREAL framework and as a continuation of our first publication. Results: During this study, categories of public health response and vaccination dominated the policies enacted. The SSA was the main author of publications. There seems to be a more unified policy response. However, health inequalities persist. Conclusions: The Mexican government continued to be reactive to the increase in cases or the arrival of new variants, rather than preventative. Research and development of policies need to work together in soaring cases like COVID-19 to work more effectively against the economic and epidemiological burden of a pandemic. It is suggested that this "vaccination" should be included in the RREAL classification. Other sectors (i.e. the ministry of foreign affairs) should be considered relevant players in the future management of a pandemic.

[Nutritional recovery of underweight adolescents with anorexia nervosa: analysis of a hospital protocol]. / Recuperación nutricional de adolescentes de bajo peso con anorexia nerviosa: análisis de un protocolo intrahospitalario.

Introduction: Background: anorexia nervosa (AN) is a severe psychiatric pathology that has one of the highest mortality rates among mental illnesses, estimated at 5.1 deaths per 1,000 people/year, and is associated with high comorbidity, both psychiatric and somatic. Aim: to characterize hospitalized adolescents and their nutritional rehabilitation using a standardized protocol. Methods: a descriptive-retrospective study of adolescent patients hospitalized at the San Carlos of Apoquindo Clinic with a diagnosis of AN, hemodynamically stable and without refeeding syndrome criteria, between 2015 and 2021. Epidemiological, clinical, and nutritional data of the patients were analyzed. Results: of 46 patients studied, 37 were female; the average length of stay was 45.4 (SD ± 36.1) days; 53.8 % of the patients had mood disorder as psychiatric comorbidity, and the most common personality trait was obsessive-compulsive (36.9 %); the most frequent somatic comorbidity was thyroid pathology (19.2 %). The initial oral caloric intake was 1467 (SD ± 479) kcal, with an average weekly increase of 400 kcal, reaching 2430 (SD ± 457) kcal at discharge. An average body mass index (BMI%) percentage change of 7.8 % (SD ± 6.1) was obtained. Conclusions: this is the first national study that describes the nutritional rehabilitation of adolescents with AN and the length of hospitalization required to achieve it.

Conclusión: este es el primer estudio a nivel nacional que describe la rehabilitación nutricional de adolescentes con AN y el tiempo de hospitalización que se requiere para lograrla.

The Impact of COVID-19 on Education: A Meta-Narrative Review.

The rapid and unexpected onset of the COVID-19 global pandemic has generated a great degree of uncertainty about the future of education and has required teachers and students alike to adapt to a new normal to survive in the new educational ecology. Through this experience of the new educational ecology, educators have learned many lessons, including how to navigate through uncertainty by recognizing their strengths and vulnerabilities. In this context, the aim of this study is to conduct a bibliometric analysis of the publications covering COVID-19 and education to analyze the impact of the pandemic by applying the data mining and analytics techniques of social network analysis and text-mining. From the abstract, title, and keyword analysis of a total of 1150 publications, seven themes were identified: (1) the great reset, (2) shifting educational landscape and emerging educational roles (3) digital pedagogy, (4) emergency remote education, (5) pedagogy of care, (6) social equity, equality, and injustice, and (7) future of education. Moreover, from the citation analysis, two thematic clusters emerged: (1) educational response, emergency remote education affordances, and continuity of education, and (2) psychological impact of COVID-19. The overlap between themes and thematic clusters revealed researchers' emphasis on guaranteeing continuity of education and supporting the socio-emotional needs of learners. From the results of the study, it is clear that there is a heightened need to develop effective strategies to ensure the continuity of education in the future, and that it is critical to proactively respond to such crises through resilience and flexibility.

Facial Seborrheic Dermatitis in HIV-Seropositive Patients: Evaluation of the Efficacy and Safety of a Non-Steroidal Cream Containing Piroctone Olamine, Biosaccharide Gum-2 and Stearyl Glycyrrhetinate - A Case Series.

Facial seborrheic dermatitis is common in HIV-positive patients, and the presence of facial lesions can affect quality of life. The management and control of lesions can be frustrating for both physicians and patients. In this pilot clinical study, we clinically evaluated the effectiveness of a topical non-steroidal cream in treating mild to moderate facial seborrheic dermatitis in 20 HIV-positive patients. The patients applied a twice-a-day topical cream containing zinc PCA, piroctone olamine, hydroxyphenyl propamidobenzoic acid, biosaccharide gum-2, and stearyl glycyrrhetinate for 12 weeks with no topical or oral antifungal or corticosteroid treatment. Signs and symptoms and tolerance were assessed before, during, and at the end of treatment. All of the patients showed clinical improvement after 4 and 12 weeks of treatment. None of the patients had no response to treatment, and no adverse effects were reported. No rescue therapy with corticosteroids was needed. The patients reported a very noticeable improvement in their skin which contributed to high compliance with the protocol requirement.

Intranasal dexamethasone: a new clinical trial for the control of inflammation and neuroinflammation in COVID-19 patients.

BACKGROUND: By end December of 2021, COVID-19 has infected around 276 million individuals and caused over 5 million deaths worldwide. Infection results in dysregulated systemic inflammation, multi-organ dysfunction, and critical illness. Cells of the central nervous system are also affected, triggering an uncontrolled neuroinflammatory response. Low doses of glucocorticoids, administered orally or intravenously, reduce mortality among moderate and severe COVID-19 patients. However, low doses administered by these routes do not reach therapeutic levels in the CNS. In contrast, intranasally administered dexamethasone can result in therapeutic doses in the CNS even at low doses. METHODS: This is an approved open-label, multicenter, randomized controlled trial to compare the effectiveness of intranasal versus intravenous dexamethasone administered in low doses to moderate and severe COVID-19 adult patients. The protocol is conducted in five health institutions in Mexico City. A total of 120 patients will be randomized into two groups (intravenous vs. intranasal) at a 1:1 ratio. Both groups will be treated with the corresponding dexamethasone scheme for 10 days. The primary outcome of the study will be clinical improvement, defined as a statistically significant reduction in the NEWS-2 score of patients with intranasal versus intravenous dexamethasone administration. The secondary outcome will be the reduction in mortality during hospitalization. CONCLUSIONS: This protocol is currently in progress to improve the efficacy of the standard therapeutic dexamethasone regimen for moderate and severe COVID-19 patients. TRIAL REGISTRATION: ClinicalTrials.gov NCT04513184 . Registered November 12, 2020. Approved by La Comisión Federal para la Protección contra Riesgos Sanitarios (COFEPRIS) with identification number DI/20/407/04/36. People are currently being recruited.

Health-care guidelines and policies during the COVID-19 pandemic in Mexico: A case of health-inequalities.

BACKGROUND: Heterogeneous government responses have been reported in reaction to COVID-19. The aim of this study is to generate an exploratory review of healthcare policies published during COVID-19 by health-care institutions in Mexico. Analyzing policies within different health sub-systems becomes imperative in the Mexican case due to the longstanding fragmentation of the health-care system and health inequalities. DATA AND METHODS: Policies purposely included in the analysis were published by four public health institutions (IMSS, ISSSTE, SSA and PEMEX) during the COVID-19 epidemic in Mexico (from February 29th to June 15th, 2020) on official institutional websites. Researchers reviewed each document and classified them into seven policy categories set by the Rapid Research Evaluation and Appraisal Lab (RREAL): public health response, health-care delivery, human resources, health-system infrastructure and supplies, clinical response, health-care management, and epidemiological surveillance. RESULTS: Policy types varied by health institution. The largest number of policies were aimed at public health responses followed by health-care delivery and human resources. Policies were mainly published during the community transmission phase. CONCLUSIONS: The pandemic exposed underlying health-care system inequalities and a reactive rather than prepared response to the outbreak. Additionally, this study outlines potential policy gaps and delays in the response that could be avoided in the future.

Extracellular Vesicles in NAFLD/ALD: From Pathobiology to Therapy.

In recent years, knowledge on the biology and pathobiology of extracellular vesicles (EVs) has exploded. EVs are submicron membrane-bound structures secreted from different cell types containing a wide variety of bioactive molecules (e.g., proteins, lipids, and nucleic acids (coding and non-coding RNA) and mitochondrial DNA). EVs have important functions in cell-to-cell communication and are found in a wide variety of tissues and body fluids. Better delineation of EV structures and advances in the isolation and characterization of their cargo have allowed the diagnostic and therapeutic implications of these particles to be explored. In the field of liver diseases, EVs are emerging as key players in the pathogenesis of both nonalcoholic liver disease (NAFLD) and alcoholic liver disease (ALD), the most prevalent liver diseases worldwide, and their complications, including development of hepatocellular carcinoma. In these diseases, stressed/damaged hepatocytes release large quantities of EVs that contribute to the occurrence of inflammation, fibrogenesis, and angiogenesis, which are key pathobiological processes in liver disease progression. Moreover, the specific molecular signatures of released EVs in biofluids have allowed EVs to be considered as promising candidates to serve as disease biomarkers. Additionally, different experimental studies have shown that EVs may have potential for therapeutic use as a liver-specific delivery method of different agents, taking advantage of their hepatocellular uptake through interactions with specific receptors. In this review, we focused on the most recent findings concerning the role of EVs as new structures mediating autocrine and paracrine intercellular communication in both ALD and NAFLD, as well as their potential use as biomarkers of disease severity and progression. Emerging therapeutic applications of EVs in these liver diseases were also examined, along with the potential for successful transition from bench to clinic.

Extracellular vesicles derived from fat-laden hepatocytes undergoing chemical hypoxia promote a pro-fibrotic phenotype in hepatic stellate cells.

BACKGROUND: The transition from steatosis to non-alcoholic steatohepatitis (NASH) is a key issue in non-alcoholic fatty liver disease (NAFLD). Observations in patients with obstructive sleep apnea syndrome (OSAS) suggest that hypoxia contributes to progression to NASH and liver fibrosis, and the release of extracellular vesicles (EVs) by injured hepatocytes has been implicated in NAFLD progression. AIM: To evaluate the effects of hypoxia on hepatic pro-fibrotic response and EV release in experimental NAFLD and to assess cellular crosstalk between hepatocytes and human hepatic stellate cells (LX-2). METHODS: HepG2 cells were treated with fatty acids and subjected to chemically induced hypoxia using the hypoxia-inducible factor 1 alpha (HIF-1α) stabilizer cobalt chloride (CoCl2). Lipid droplets, oxidative stress, apoptosis and pro-inflammatory and pro-fibrotic-associated genes were assessed. EVs were isolated by ultracentrifugation. LX-2 cells were treated with EVs from hepatocytes. The CDAA-fed mouse model was used to assess the effects of intermittent hypoxia (IH) in experimental NASH. RESULTS: Chemical hypoxia increased steatosis, oxidative stress, apoptosis and pro-inflammatory and pro-fibrotic gene expressions in fat-laden HepG2 cells. Chemical hypoxia also increased the release of EVs from HepG2 cells. Treatment of LX2 cells with EVs from fat-laden HepG2 cells undergoing chemical hypoxia increased expression pro-fibrotic markers. CDAA-fed animals exposed to IH exhibited increased portal inflammation and fibrosis that correlated with an increase in circulating EVs. CONCLUSION: Chemical hypoxia promotes hepatocellular damage and pro-inflammatory and pro-fibrotic signaling in steatotic hepatocytes both in vitro and in vivo. EVs from fat-laden hepatocytes undergoing chemical hypoxia evoke pro-fibrotic responses in LX-2 cells.

Effect of moderate thermal treatments on the inactivation of a strain of Listeria monocytogenes and physicochemical properties of soursop pulp.

Soursop (Annona muricata L.) is a commercially important tropical fruit, whether fresh or processed as a pasteurized or frozen pulp used to prepare juice, drinks, nectar, ice cream, popsicles, and desserts. Besides preserving quality, another preoccupation in the processing of fruit pulps is product safety. Several studies show the association between pulp processing and the development of various microorganisms; however, few have focused on the association between L. monocytogenes and the pulp of sour fruits. The objective was to evaluate the effect of moderate thermal treatments on the inactivation of L. monocytogenes and the physicochemical properties in soursop pulp in order to determine the best processing conditions that will allow to maintain quality as well as to achieve an adequate level of safety. Thermal inactivation kinetics were obtained for L. monocytogenes inoculated in soursop pulp at five levels of temperature (50, 52.5, 55, 57.5, and 60 ℃) and different exposure times (0-60 min). The survival curves did not suggest a log-linear relationship, and were, consequently, fitted to the modified Gompertz equation. The results indicated that the modified Gompertz equation provided an acceptable goodness of fit. Five-log10 cycles reductions of L. monocytogenes were achieved at 50 ℃/60 min, 52.5 ℃/16 min, 55 ℃/10 min, 57.5 ℃/5 min, and 60 ℃/1.25 min. These 5-log10 treatments applied to the soursop pulp indicated that the soursop pulp showed changes in the color parameters and a decrease in the content of total sugars, reducing sugars, ascorbic acid, total phenols, and pH.

Infectious and non-infectious diseases burden among Haitian immigrants in Chile: a cross-sectional study.

Chile has become a popular destination for migrants from South America and the Caribbean (low- and middle-income countries migration). Close to 200.000 Haitian migrants have arrived in Chile. Infectious and non-infectious disease burden among the Haitian adult population living in Chile is unknown. This study aimed to acquire the basic health information (selected transmissible and non-transmissible conditions) of the Haitian adult population living in Chile. A cross-sectional survey was performed, inviting Haitian-born residents in Chile older than 18 years old. Common conditions and risk factors for disease were assessed, as well as selected transmissible conditions (HIV, HBV, and HCV). 498 participants (60.4% female) from 10 communities in two regions of Chile were surveyed. Most subjects had never smoked (91.5%), and 80% drank less than one alcohol unit per month. The mean BMI was 25.6, with 45% of participants having a normal BMI (20-25). Hypertension was present in 31.5% (33% in the 25-44 age group). Prevalence of HIV was 2.4% (95 CI 1.3-4.2%), hepatitis B (HBsAg positive) was 3.4% (95 CI 2.1-5.5%), and hepatitis C was 0% (95 CI 0.0-0.9%). Quality of life showed a significant prevalence of depression and anxiety markers, particularly in those arriving in Chile less than 1 year ago. Low prevalence of obesity, diabetes, smoking, and drinking and estimated cardiovascular risk were found. Nonetheless, hypertension at a younger age, disproportionately higher prevalence of HIV and HBV infection and frequent markers of anxiety and depression were also found. Public policies for detecting and treating hypertension, HIV, and HBV screening, offering HBV vaccination, and organizing mental health programs for Haitian immigrants, are urgently needed.

[Health-related quality of life, psychosocial variables, and academic performance in school-age girls who practice dancing. A comparative study]. / Calidad de vida relacionada con la salud, variables psicosociales y rendimiento académico en mujeres de edad escolar practicantes de danza. Un estudio comparativo.

INTRODUCTION: Introduction: psychosocial development affects health-related quality of life (HRQoL) and academic performance (AP). Objective: to determine differences in self-esteem, body image dissatisfaction, and HRQoL between girls who practice dancing, girls who play sports, and girls who perform no physical activity. To determine the association between these variables and AP. Method: 252 girls between 9 and 14 years of age were enrolled into three groups: no physical activity (NAF, n = 99, 10.25 ± 1.10 years, BMI = 21.97 ± 11.69 kg/m2), sports (DEP, n = 82, 10.54 ± 1.19 years, BMI = 21.36 ± 3.99 kg/m2), and dancing (DAN, n = 71, 10.51 ± 1.2 years, BMI = 20.08 ± 3.68 kg/m2), and anthropometric parameters, psychosocial variables, HRQoL, and AP were measured. Results: HRQoL scores (p < 0.001) and global self-esteem (p = 0.001) were higher for girls who practiced dancing. Regarding HRQoL-related questions (Have you felt well and in good physical condition? (38.0%, p = 0.007); Are you doing well in school? (31.0%, p = 0.010); have you been able to pay attention? (39.4%, p = 0.023)), girls who practiced dancing reported the highest proportion of "very much" responses. The results of a multiple regression analysis showed that HRQoL (B = 0.023, p = 0.001) and school self-esteem (B = 0.054, p = 0.010) were associated with AP. Conclusion: girls who practice dancing have greater self-esteem, HRQoL, and physical and school well-being. This suggests that practicing dancing is an activity that may potentially improve psychosocial well-being and school adaptation.

INTRODUCCIÓN: Introducción: el desarrollo psicosocial afecta a la calidad de vida relacionada con la salud (CVRS) y el rendimiento académico (RA). Objetivo: determinar si existen diferencias en cuanto a niveles de autoestima, insatisfacción con la imagen corporal y CVRS entre niñas practicantes de danza, niñas practicantes de deportes y niñas que no realizan actividad física. Determinar la asociación entre estas variables y el RA. Método: participaron 252 niñas de entre 9 y 14 años, divididas en tres grupos: no practicantes de actividad física (NAF, n = 99, 10,25 ± 1,10 años, IMC = 21,97 ± 11,69 kg/m2), practicantes de deporte (DEP, n = 82, 10,54 ± 1,19 años, IMC = 21,36 ± 3,99 kg/m2) y practicantes de danza (DAN, n = 71, 10,51 ± 1,2 años, IMC= 20,08 ± 3,68 kg/m2), y se realizaron mediciones antropométricas, psicosociales, de la CVRS y del RA. Resultados: el puntaje de CVRS (p < 0,001) y de autoestima global (p = 0.001) fue mayor en las niñas practicantes de danza. En relación a las preguntas sobre calidad de vida (¿Te has sentido bien y en buen estado físico? (38,0%, p = 0,007); ¿Te ha ido bien en el colegio? (31,0%, p = 0,010); ¿Has sido capaz de poner atención? (39,4%, p = 0,023)) las escolares practicantes de danza eligieron la respuesta "muchísimo" en mayor proporción. Los resultados del análisis de regresión lineal mostraron que la CVRS (B = 0,023, p = 0,001) y la autoestima escolar (B = 0,054, p = 0,010) presentan asociación con el RA. Conclusión: las escolares practicantes de danza presentaron mayor autoestima, CVRS y percepción de bienestar físico y escolar. Esto indica que la práctica de la danza es una actividad que puede favorecer el desarrollo psicosocial y la adaptación escolar.

Urinary Tract Infections in College and Non-College Women from Colombia.

OBJECTIVE: To compare college and non-college women in terms of the frequency of, etiology of, and risk factors associated with urinary tract infections. METHODS: This was a cross-sectional study conducted in Cartagena, Colombia, with 258 female college students and 256 female non-college students from 15 to 34 years old. The participants were interviewed and completed a questionnaire assessing the risk factors associated with urinary tract infections. Urine samples were examined by urinalysis and to look for signs of urinary tract infection, when found, were confirmed by culture. Isolated bacteria were tested for antimicrobial susceptibility using the Kirby-Bauer test. A chi-square test and binary logistic regression were used to analyze the data. RESULTS: Urinary tract infections were found in 7.8% of the participating college women and 9.4% of the participating non-college women. E. coli was the most frequent uropathogen found in the members of the 2 groups. The majority of the isolated bacteria were highly resistant to ß-lactams. Binary logistic regression analysis showed that in the college women, the predictor variables of having a urinary tract infection were the presence of nitrites, leucocytes, and urinary urgency. In the case of the non-college women, the predictor variables were the presence of nitrites and cystitis in the last 2 years. CONCLUSION: The frequencies of urinary tract infection were similar in both groups. These individuals might have been taking non-prescribed antibiotics or failing to comply with a prescribed treatment or bacteria are of hospital origin.
