Retrospective study of risk markers for developing high-grade anal intraepithelial neoplasm in men who have sex with men living with HIV. / Estudio retrospectivo que evalúa marcadores de riesgo de desarrollar lesión escamosa intraepitelial anal de alto grado en hombres que tiene sexo con hombres y viven con el virus de inmunodeficiencia humana.

High-grade anal intraepithelial squamous lesion is significantly prevalent among men who have sex with men and are infected with the human immunodeficiency virus. This condition-the precursor to anal cancer-significantly increases the risk of developing it. Conversely, low-grade anal intraepithelial squamous typically follow a benign course and usually regress spontaneously. MATERIALS AND METHODS: To describe a population of men who have sex with men living with human immunodeficiency virus followed in a specialized anal cancer screening unit we conducted an observational, retrospective, and single-center study was. RESULTS: Ninety-four patients were analyzed, with a mean age of 39 ± 9 years, and a 87% positivity rate for high-risk human papillomavirus (HR-HPV). At the initial visit, 47% presented with low-grade squamous intraepithelial lesions. The progression rate to high-grade squamous intraepithelial lesion was 37.2 per 100,000 patients/year. None of the patients developed anal cancer. Tobacco and alcohol consumption were associated with this progression. DISCUSSION: In this series, longer duration of HIV infection, tobacco and alcohol use and the presence of HR-HPV were significantly associated with the occurrence of high-grade intraepithelial lesions. A lower risk of progression was seen in patients with higher education. CONCLUSION: In men who have sex with men living with HIV, the association of factors such as smoking, alcohol, the presence of HR-HPV and an increased burden of human papillomavirus disease makes these patients more susceptible to develop high-grade anal squamous lesions.

Identification of a Female-Produced Sex Attractant Pheromone of the Winter Firefly, Photinus corruscus Linnaeus (Coleoptera: Lampyridae).

Firefly flashes are well-known visual signals used by these insects to find, identify, and choose mates. However, many firefly species have lost the ability to produce light as adults. These "unlighted" species generally lack developed adult light organs, are diurnal rather than nocturnal, and are believed to use volatile pheromones acting over a distance to locate mates. While cuticular hydrocarbons, which may function in mate recognition at close range, have been examined for a handful of the over 2000 extant firefly species, no volatile pheromone has ever been identified. In this study, using coupled gas chromatography - electroantennographic detection, we detected a single female-emitted compound that elicited antennal responses from wild-caught male winter fireflies, Photinus corruscus. The compound was identified as (1S)-exo-3-hydroxycamphor (hydroxycamphor). In field trials at two sites across the species' eastern North American range, large numbers of male P. corruscus were attracted to synthesized hydroxycamphor, verifying its function as a volatile sex attractant pheromone. Males spent more time in contact with lures treated with synthesized hydroxycamphor than those treated with solvent only in laboratory two-choice assays. Further, using single sensillum recordings, we characterized a pheromone-sensitive odorant receptor neuron in a specific olfactory sensillum on male P. corruscus antennae and demonstrated its sensitivity to hydroxycamphor. Thus, this study has identified the first volatile pheromone and its corresponding sensory neuron for any firefly species, and provides a tool for monitoring P. corruscus populations for conservation and further inquiry into the chemical and cellular bases for sexual communication among fireflies.

Trends in COVID-19-related in-hospital mortality in women and men.

INTRODUCTION: Whether political, scientific and medical development in a country is associated with better clinical results according to gender in patients with COVID-19 has not yet been clearly elucidated. OBJECTIVE: To determine the trends of COVID-19-related in-hospital mortality in women and men from March 2020 to February 2022. METHODS: Clinical data of all patients with COVID-19 cared for at 21 Spanish hospitals were used, both of those who were discharged and of those who died during hospitalization. The association between hospital length of stay and mortality was analyzed with logistic regression models. RESULTS: Out of 7,974 patients that were included, 3,234 were women; 928 patients died. A significant decreasing trend in mortality was identified. When the analysis was carried out by gender, no significant mortality trend was found in women (OR = 0.96 [0.90-1.03], p = 0.239), while in men there was a significant decreasing trend identified (OR = 0.87 [0.82-0.92], p < 0.001). CONCLUSION: Health policies, together with clinical and preventive interventions, may explain these results. Response to treatment and behavioral differences may explain why mortality does not decrease for women.

INTRODUCCIÓN: Todavía no se comprende si el desarrollo político, científico y médico en un país se asocia a mejores resultados clínicos de los pacientes con COVID-19 según el sexo. OBJETIVO: Determinar las tendencias de mortalidad hospitalaria asociada a COVID-19 en mujeres y hombres entre marzo de 2020 y febrero de 2022. MÉTODOS: Se utilizaron los datos clínicos de todos los pacientes con COVID-19 atendidos en 21 hospitales españoles, tanto de quienes fueron dados de alta como de quienes fallecieron durante el ingreso. La asociación entre la fecha del ingreso y la mortalidad se analizó con modelos de regresión logística. RESULTADOS: Fueron incluidos 7974 pacientes, de los cuales 3234 fueron mujeres y 928 fallecieron. Se encontró una tendencia significativa y decreciente en la mortalidad según avanzaba la fecha del ingreso. Cuando el análisis se realizó por sexos, no se halló una tendencia significativa en las mujeres (RM = 0.96 [0.90-1.03], p = 0.239), pero sí en los hombres (RM = 0.87 [0.82-0.92], p < 0.001). CONCLUSIÓN: Las políticas de salud, junto con las intervenciones clínicas y preventivas, pueden dar cuenta de los resultados. Diferencias en la respuesta al tratamiento o en los comportamientos pueden explicar por qué la mortalidad no disminuye en las mujeres.

Characteristics and impact of sex in a cohort of patients with primary sclerosing cholangitis: Experience of a transplant center in the Mediterranean basin. / Características e impacto del sexo en una cohorte de pacientes con colangitis esclerosante primaria: experiencia de un centro trasplantador de la cuenca mediterránea.

BACKGROUND AND AIMS: Primary sclerosing cholangitis (PSC) is a rare cholestatic liver disease that typically affects middle-aged men with ulcerative colitis (UC). However, recent studies point out to epidemiological changes. Our aim was to determine if the epidemiology, clinical course and outcome of patients with PSC followed at a reference hepatology center resemble what is described in the literature. PATIENTS AND METHOD: Retrospective search of patients with a diagnosis of PSC treated in our center between 2000 and 2019. RESULTS: Cohort of 55 patients (mean age: 37 years), 44% women. Most were large duct type (79%). Most diagnoses were made after 2011. At time of diagnosis, 63% of patients were asymptomatic. The median time from suspicion to diagnosis was 2 years. After a mean follow-up time of 7 years, one third developed cirrhosis, and 25% required liver transplantation (LT); among these, the disease recurred in almost half. Inflammatory bowel disease (IBD) was present in 45%, especially UC. Although statistical significance was not reached, PSC in women was characterized by higher rate of asymptomatic presentation and more frequent association with UC versus other forms of IBD. Women also had more frequently cirrhosis at diagnosis and required LT more often than men. CONCLUSION: The epidemiology of PSC is changing. The number of women affected is greater than what was expected from the literature, with a recent increase in incidence. There seems to be differences between sexes in the form of presentation and disease course that should be confirmed in subsequent studies.

Missing Piece of the Puzzle: Evaluating a General Meaning of Sex Measure.

The presence of and search for meaning has divergent and salient outcomes for individuals' physical, mental, and emotional well-being. Although numerous domains of meaning have been examined, the literature on the meaning of sex is sparse and lacks a quantitative measure. In this study, we evaluated a new general Meaning of Sex (MOS) Measure that captured the presence of (MOS-P) and search for (MOS-S) the meaning of sex by analyzing how these subscales were associated with important relational and sexual outcomes (i.e., relationship stability and satisfaction and sexual satisfaction) in two samples. For Sample 1, all participants (N = 865) reported engaging in what they considered to be sexual intercourse and were either single or in a relationship. For Sample 2, all participants (N = 884) reported being in a committed relationship for at least two years. With both samples, confirmatory factor analyses showed good construct validity as the two subscales were distinct from one another and had good reliability. The analyses also demonstrated divergent validity between both scales and meaning in life, sexual motivations, sexual beliefs, and religiosity. The MOS-S had a strong (and negative) association with relationship stability in both samples. The MOS-P had a strong (and positive) association with relationship satisfaction in both samples.

La presencia y la búsqueda de significado tiene consecuencias divergentes y prominentes para el bienestar físico, mental y emocional de las personas. Aunque se han analizado varios componentes de significado, la bibliografía sobre el significado del sexo es escasa y carece de un instrumento de medición cuantitativo. En este estudio, evaluamos un nuevo instrumento general de medición del significado del sexo que captó la presencia y la búsqueda del significado del sexo analizando cómo estas subescalas estuvieron asociadas con resultados sexuales y relacionales importantes (p. ej.: la estabilidad y la satisfacción en la relación y la satisfacción sexual) en dos muestras. En la muestra 1, todos los participantes (N = 865) informaron participar en lo que consideraron relaciones sexuales y estaban solteros o en una relación. En la muestra 2, todos los participantes (N = 884) informaron estar en una relación de pareja estable durante al menos dos años. Con ambas muestras, los análisis factoriales confirmatorios indicaron una buena validez de constructo, ya que las dos subescalas eran distintas entre sí y tenían buena fiabilidad. Los análisis también indicaron una validez divergente entre ambas escalas y el significado en la vida, las motivaciones sexuales, las creencias sexuales y la religiosidad. La búsqueda del significado del sexo tuvo una asociación fuerte (y negativa) con la estabilidad de la relación en ambas muestras. La presencia del significado del sexo tuvo una asociación fuerte (y positiva) con la satisfacción en la relación en ambas muestras.

Heteronormative Relationship Education for Same-Gender Couples.

In recent years, same-gender group-based relationship education has emerged as a viable intervention to prevent relationship distress among same-gender couples. However, many of these programs are conducted in metropolitan areas and lack the ability to reach rural populations. The current study sought to investigate whether two wide-reaching web-based heteronormative relationship education programs could positively impact same-gender relationships. In a sample of 49 same-gender couples, heteronormative relationship education had small (Cohen's d = 0.16-0.39) but reliably positive effects on key areas of relationship functioning and perceived stress relative to a waitlist control group. Additionally, when same-gender couples were matched with different-gender individuals with similar baseline characteristics, no reliable differences between the two groups emerged even though the program effects were sometimes half as large for same-gender couples. Finally, same-gender participants were as satisfied with the program as the matched different-gender individuals. Though the results of the present study indicate that heteronormative relationship education can be helpful for same-gender couples, additional tailoring should be undertaken to ensure that same-gender couples experience as much benefit as possible. Estimates from the current study could be used in future studies to detect what might be small-sized differences.

En los últimos años, la capacitación en relaciones grupal y del mismo sexo ha surgido como una intervención viable para prevenir el distrés relacional entre parejas del mismo género. Sin embargo, muchos de estos programas se realizan en áreas metropolitanas y no pueden llegar a las poblaciones rurales. El presente estudio tuvo como finalidad investigar si dos programas de capacitación heteronormativa en relaciones, por Internet y de amplio alcance podrían tener un efecto positivo en las relaciones del mismo género. En una muestra de 49 parejas del mismo género, la capacitación heteronormativa en relaciones tuvo efectos pequeños (d de Cohen = 0.16-0.39) pero fiablemente positivos en áreas clave del funcionamiento relacional y del estrés percibido respecto de un grupo control en lista de espera. Además, cuando las parejas del mismo género se igualaron con personas de diferente género con características iniciales similares, no surgieron diferencias fiables entre los dos grupos, aunque los efectos del programa fueron a veces de la mitad para las parejas del mismo género. Finalmente, los participantes del mismo género estuvieron tan satisfechos con el programa como las personas de diferente género con quienes se las igualó. Aunque los resultados del presente estudio indican que la capacitación heteronormativa en relaciones puede ser útil para parejas del mismo género, deberían realizarse más adaptaciones para garantizar que las parejas del mismo género tengan todos los beneficios posibles. En futuros estudios podrían usarse cálculos del presente estudio para detectar las posibles diferencias pequeñas.

[Bibliometric analysis of female authorship in original articles in the journal ATENCIÓN PRIMARIA]. / Análisis bibliométrico de la autoría femenina en artículos originales en la revista ATENCIÓN PRIMARIA.

OBJECTIVES: To determine the percentage of female authors in original articles published during 2periods, in the journal of Atención Primaria (Primary Care), and to examine the differences between the categories of authorship (first, last author, and co-author) between both periods. DESIGN: Cross-sectional study. SETTING: Feminine scientific production published during the periods 2007-2008 and 2017-2018. PARTICIPANTS: The study was focused on original articles. MAIN MEASUREMENTS: The following variables were collected in an ad hoc form: gender based on the name of the author, total number of women and men appearing as authors, and order of authorship. Absolute and relative authorship frequencies were calculated, and the χ2 test was used to examine the evolution of the percentages by type of authorship and gender. RESULTS: A total of 108 articles were analysed in 2007-2008, and 100 in 2017-2018. No statistically significant differences were observed between the mean numbers of women authors within and between periods. In 2007-2008 a total of 548 female authors were identified and 540 in 2017-2018, the percentage of female authors was 48.7% and 54.4%, respectively. Only an increase in the percentage of first authors was observed between periods. CONCLUSIONS: Practically one out of every 2authors of original articles published in the journal Atención Primaria was female. There was also a significant increase in the percentage of female first authors between the 2periods. Nevertheless, and despite the greater number of health workers, the number of latest female authors remain unchanged, which points to the persistence of female under-representation.

Minority Stress and Same-Sex Relationship Satisfaction: The Role of Concealment Motivation.

Most lesbian, gay, and bisexual (LGB) people want a stable, satisfying romantic relationship. Although many of the predictors of relationship outcomes are similar to those of heterosexual couples, same-sex couples face some additional challenges associated with minority stress that also impact upon relationship quality. Here, we investigate the association between minority stressors and relationship quality in a sample of 363 adults (M age = 30.37, SD = 10.78) currently in a same-sex romantic relationship. Internalized homophobia and difficulties accepting one's LGB identity were each negatively associated with relationship satisfaction via heightened concealment motivation. We also examined the protective role of identity affirmation on relationship quality, finding a direct positive relationship between the two variables. Minority stressors were negatively associated with couple relationship satisfaction via heightened concealment motivation. The finding that identity affirmation directly predicted increased couple satisfaction also highlights the important role of protective factors in same-sex couple relationships.

La mayoría de las personas lesbianas, gais y bisexuales (LGB) desean una relación amorosa estable y satisfactoria. Aunque muchos de los predictores de las complicaciones en las relaciones son similares a los de las parejas heterosexuales, las parejas del mismo sexo enfrentan algunas otras dificultades asociadas con el estrés de las minorías que también repercuten en la calidad de la relación. Aquí investigamos la asociación entre los factores desencadenantes de estrés en las minorías y la calidad de la relación en una muestra de 363 adultos (edad promedio = 30.37, desviación estándar = 10.78) que están actualmente en una relación amorosa del mismo sexo. La homofobia internalizada y las dificultades para aceptar la identidad LGB propia estuvieron asociadas negativamente con la satisfacción en la relación mediante un incremento de la motivación por la ocultación. También analizamos el papel protector que desempeña la afirmación de la identidad en la calidad de la relación y encontramos una relación positiva directa entre las dos variables. Los factores desencadentantes de estrés en las minorías estuvieron asociados negativamente con la satisfacción en la relación de pareja mediante un incremento de la motivación por la ocultación. El hallazgo de que la afirmación de la identidad predijo directamente una mayor satisfacción en la pareja también destaca el papel importante que desempeñan los factores protectores de las relaciones de pareja del mismo sexo.

A developmental origins perspective on the emergence of violent behavior in males with prenatal substance exposure.

Children with prenatal substance exposure are at increased risk for externalizing behavior problems and violence. However, the contribution of early life experiences for placing these individuals at risk is not well understood. Utilizing a sample of 1,388 children with prenatal substance exposure from the Maternal Lifestyle Study, we attempt to shed light on these contributing factors by examining the impact of infant temperament, maternal sensitivity, and early life stress on the expression of violent behavior at ages 12 through 14 years. Males may be more at risk for increases in violent behavior in early adolescence through a number of early life experiences, such as variability in responses to maternal flexibility and engagement related to individual differences in temperament, as well as exposure to early adversity. Comparing two prevailing developmental theoretical frameworks, deficit models and differential susceptibility, we aim to understand the developmental origins of violent behavior in males by identifying children who may be most susceptible to early caregiving experiences.

The effect of age and sex on the diagnostic yield of the echocardiogram in patients with syncope. / Efecto de la edad y el sexo en el rendimiento diagnóstico del ecocardiograma en pacientes con síncope.

INTRODUCTION: Syncope is the motivation for numerous diagnostic tests, among them transthoracic echocardiography (TTE); however, previous evidence suggests there is little utility in this test. Our objective was to assess its diagnostic yield in syncope, analysing the effect of age and sex. MATERIAL AND METHODS: We conducted an observational study that included patients with syncope and who underwent TTE between 1990-2015. We defined diagnostic findings related to syncope and performed a descriptive analysis, assessing the diagnostic yield (overall and according to age and sex). RESULTS: The study included 3,302 patients and measured a diagnostic yield of 8.8%; the most common finding was ventricular dysfunction (4.5%). The probability of a diagnostic TTE significantly increased with age (p<.001) but was low for patients younger than 50 years (2.3%). The male sex was significantly related with a diagnostic TTE (p<.001), mostly due to the higher rate of ventricular dysfunction. CONCLUSIONS: The diagnostic yield of TTE in patients with syncope is moderate, low in patients younger than 50 years and lower in women than in men. These factors should be considered when conducting a diagnostic study of patients with syncope.

A Population-Based Comparison of Female and Male Same-Sex Parent and Different-Sex Parent Households.

This investigation compared Dutch same-sex parent and different-sex parent households on children's psychological well-being, parenting stress, and support in child rearing. It was also assessed whether associations among children's well-being, parenting stress, and support in child rearing were different in the two household types. Data were based on a nationally representative survey (N = 25,250). Matching was used to enhance similarity in background characteristics between both types of families. Parental and child characteristics were matched for 43 female same-sex parent, 52 male same-sex parent, and 95 different-sex parent households with offspring between 5 and 18 years old. No significant differences were found on children's well-being, problems in the parent-child relationship, being worried about the child, or the use of formal and informal support between mothers in same-sex and different-sex parent households or for fathers in same-sex and different-sex parent households. Regarding perceived confidence in child rearing, fathers in same-sex parent households and mothers in different-sex parent households felt less competent than their counterparts. Neither the associations between children's well-being and the predictors (parenting stress variables) nor those between support and the predictors (parenting stress and children's well-being) differed along household type. In this population-based study, the similarity in child outcomes regardless of household type confirms the results of prior investigations based on convenience samples. These findings are pertinent to family therapists, practitioners, court officials, and policymakers who seek information on parenting experiences and child outcomes in female and male same-sex parent families.

Seasonal variation in child mortality in rural Guinea-Bissau.

OBJECTIVES: In many African countries, child mortality is higher in the rainy season than in the dry season. We investigated the effect of season on child mortality by time periods, sex and age in rural Guinea-Bissau. METHODS: Bandim health project follows children under-five in a health and demographic surveillance system in rural Guinea-Bissau. We compared the mortality in the rainy season (June to November) between 1990 and 2013 with the mortality in the dry season (December to May) in Cox proportional hazards models providing rainy vs. dry season mortality rate ratios (r/d-mrr). Seasonal effects were estimated in strata defined by time periods with different frequency of vaccination campaigns, sex and age (<1 month, 1-11 months, 12-59 months). Verbal autopsies were interpreted using InterVa-4 software. RESULTS: From 1990 to 2013, overall mortality was declined by almost two-thirds among 81 292 children (10 588 deaths). Mortality was 51% (95% ci: 45-58%) higher in the rainy season than in the dry season throughout the study period. The seasonal difference increased significantly with age, the r/d-mrr being 0.94 (0.86-1.03) among neonates, 1.57 (1.46-1.69) in post-neonatal infants and 1.83 (1.72-1.95) in under-five children (P for same effect <0.001). According to the InterVa, malaria deaths were the main reason for the seasonal mortality difference, causing 50% of all deaths in the rainy season, but only if the InterVa included season of death, making the argument self-confirmatory. CONCLUSION: The mortality declined throughout the study, yet rainy season continued to be associated with 51% higher overall mortality.

Discrimination, Internalized Homonegativity, and Attitudes Toward Children of Same-Sex Parents: Can Secure Attachment Buffer Against Stigma Internalization?

With increasing numbers of same-sex couples raising children in the United States, discriminatory attitudes toward children of same-sex parents (ACSSP) are of increasing concern. As with other forms of stigma and discrimination, lesbian, gay, and bisexual (LGB) individuals are at risk for internalizing these societal attitudes, which can negatively affect parenting-related decisions and behaviors and the mental and physical health of their children. Secure attachment is characterized by positive views of the self as loveable and worthy of care that are understood to develop in early relationships with caregivers. Secure attachment has been associated with positive mental and physical health, including among LGB individuals and couples. This study aimed to test the potential buffering role of secure attachment against stigma internalization by examining associations among secure attachment, discrimination, internalized homonegativity (IH), and ACSSP in an online survey study of 209 U.S. adults in same-sex relationships. Bootstrap analyses supported our hypothesized moderated mediation model, with secure attachment being a buffer. Greater discrimination was indirectly associated with more negative ACSSP through greater IH for individuals with mean or lower levels, but not for individuals with higher than average levels of secure attachment, specifically because among those with higher levels of secure attachment, discrimination was not associated with IH. These findings build on and extend past research, with important implications for future research and clinical work with LGB individuals, same-sex couples, and their families, including potential implementation of interventions targeting attachment security.

ASSOCIATIONS BETWEEN EARLY MATERNAL DEPRESSIVE SYMPTOM TRAJECTORIES AND TODDLERS' FELT SECURITY AT 18 MONTHS: ARE BOYS AND GIRLS AT DIFFERENTIAL RISK?

The goal of this study was to evaluate whether there are sex differences in children's vulnerability to caregiving risk, as indexed by trajectories of maternal depressive symptoms assessed from 2 to 18 months' postpartum, and children's rated attachment security in toddlerhood, adjusting for maternal social support and demographic risk. Analyses utilized longitudinal data collected for 182 African American mother-child dyads from economically diverse backgrounds. Participants were recruited at the time of the child's birth and followed to 18 months' postpartum. Results of conditional latent growth models indicated that an increasing rate of change in level of maternal depressive symptoms over time negatively predicted toddlers' felt attachment security. Higher social support was associated with decreasing levels of maternal depressive symptoms over time whereas higher demographic risk was associated with increasing levels of maternal depressive symptoms. A subsequent multigroup conditional latent growth model revealed that child sex moderated these associations. For male (but not female) children, a rapid increase in maternal depressive symptoms was associated with lower felt attachment security at 18 months. These findings suggest that boys, as compared to girls, may be more vulnerable to early caregiving risks such as maternal depression, with negative consequences for mother-child attachment security in toddlerhood.

Differential effects of sex in a West African cohort of HIV-1, HIV-2 and HIV-1/2 dually infected patients: men are worse off.

OBJECTIVES: Several studies have reported conflicting effects of sex on HIV-1 infection. We describe differences in baseline characteristics and assess the impact of sex on HIV progression among patients at a clinic with many HIV-2 and HIV-1/2 dually infected patients. METHODS: This study utilised a retrospective cohort of treatment-naïve adults at the largest HIV clinic in Guinea-Bissau from 6 June 2005 to 1 December 2013. Baseline characteristics were assessed and the patients followed until death, transfer, loss to follow-up, or 1 June 2014. We estimated the time from the first clinic visit until initiation of ART, death or loss to follow-up using Cox proportional hazard models. RESULTS: A total of 5694 patients were included in the study, 3702 women (65%) and 1992 men (35%). Women were more likely than men to be infected with HIV-2 (19% vs. 15%, P < 0.01) or dually infected with HIV-1/2 (11% vs. 9%, P = 0.02). For all HIV types, women were younger (median 35 vs. 40 years), less likely to have schooling (55% vs. 77%) or to be married (46% vs. 67%), and had higher baseline CD4 cell counts (median 214 vs. 178 cells/µl). Men had a higher age-adjusted mortality rate (hazard rate ratio (HRR) 1.29, 95% confidence interval (CI) 1.09-1.52) and were more often lost to follow-up (HRR 1.27, 95% CI 1.17-1.39). CONCLUSION: Significant differences exist between HIV-infected men and women regardless of HIV type. Men seek treatment at a later stage and, despite better socio-economic status, have higher mortality and loss to follow-up than women.

Sex differences in nutritional status of HIV-exposed children in Rwanda: a longitudinal study.

OBJECTIVE: To examine sex differences in nutritional status in relation to feeding practices over time in a cohort of HIV-exposed children participating in a complementary feeding programme in Rwanda. METHODS: We applied a longitudinal design with three measurements 2-3 months apart among infants participating in a complementary feeding programme who were 6-12 months old at baseline. Using early feeding practices and a composite infant and child feeding index (ICFI) as indicators of dietary patterns, we conducted a multivariate analysis using a cross-sectional time series to assess sex differences in nutritional status and to determine whether there was a link to discrepancies in dietary patterns. RESULTS: Among 222 boys and 258 girls, the mean (±SD) Z-score of stunting, wasting and underweight was -2.01 (±1.59), -0.15 (±1.46), -1.19 (±1.29) for boys; for girls they were -1.46 (±1.56), 0.22 (±1.29), -0.63 (±1.19); all sex differences in all three indicators were statistically significant (P < 0.001). However, there were only minor differences in early feeding practices and none in the ICFI by sex. CONCLUSIONS: HIV-exposed male children may be at higher risk of malnutrition in low-resource setting countries than their female counterparts. However, at least in a setting where complementary foods are being provided, explanations may lie outside the sphere of dietary patterns.

[Analysis of the epidemiological pattern of Shigellosis in Barcelona between 1988 and 2012: Is it an emerging sexually transmitted infection?]. / Análisis del patrón epidemiológico de la shigelosis en Barcelona entre 1988 y 2012: ¿es una infección de transmisión sexual emergente?

INTRODUCTION: The aim of this study was to describe the evolution and epidemiologic characteristics of shigellosis patients over a 25 year period in a large city. METHODS: Shigellosis is a notifiable disease in Spain since 1988. Cases are analyzed in Barcelona residents included in the registry between 1988-2012. A descriptive analysis by sex, age, mode of transmission and Shigella species is presented. Trend analysis and time series were performed. RESULTS: Of the 559 cases analyzed, 60.15% were males. A sustained increase was observed in the trend since 2008 in males (p<0,05), especially at the expense of males who had no history of food poisoning or travel to endemic areas. The increasing tendency was greater in males from 21 to 60 years, both for S. flexneri (since 2009), and for S. sonnei (since 2004). In 2012 it was noted that in the men with S. flexneri, the 63% were men who have sex with men. CONCLUSIONS: An increased trend was detected in men who had no history of food poisoning or travel to endemic areas. This increase points to a change in the pattern of shigellosis, becoming predominantly male and its main mechanism probably by sexual transmission.

[Syphilis and human immunodeficiency virus infection: an endemic infection in men who have sex with men]. / Sífilis e infección por el virus de la inmunodeficiencia humana: una endemia en hombres que tienen sexo con hombres.

OBJECTIVE: to analyse epidemiological, clinical, and analytical features of HIV-infected men who have sex with men (MSM) diagnosed with syphilis in the Infectious Diseases Unit (Hospital Virgen de la Victoria, Málaga, Spain) during 2004-2013. PATIENTS AND METHODS: An observational study was conducted on 196 syphilis episodes in 167 MSM infected with HIV (2004-2013). Epidemiological, clinical, and analytical data were collected. Annual syphilis incidence among HIV-MSM is calculated as the number of syphilis episodes among MSM in one year divided by the number of MSM followed up in that year. RESULTS: Incidence ranged from 1.2% (2007) to 7.8% (2012). There were asymptomatic episodes in 42.8% cases, and an HIV-syphilis coincident diagnosis in 28.5%. CONCLUSIONS: The annual incidence of syphilis has increased within HIV infected MSM. One third of the syphilis episodes were simultaneous to HIV diagnosis and near half of them were asymptomatic.

A tool to assess sex-gender when selecting health research projects.

OBJECTIVE: To validate the questionnaire "Gender Perspective in Health Research" (GPIHR) to assess the inclusion of gender perspective in research projects. DESIGN: Validation study in two stages. Feasibility was analysed in the first, and reliability, internal consistence and validity in the second. WHERE: Aragón Institute of Health Science, Aragón, Spain. PARTICIPANTS: GPIHR was applied to 118 research projects funded in national and international competitive tenders from 2003 to 2012. MAIN MEASUREMENTS: Analysis of inter- and intra-observer reliability with Kappa index and internal consistency with Cronbach's alpha. Content validity analysed through literature review and construct validity with an exploratory factor analysis. RESULTS: Validated GPIHR has 10 questions: 3 in the introduction, 1 for objectives, 3 for methodology and 3 for research purpose. Average time of application was 13min Inter-observer reliability (Kappa) varied between 0.35 and 0.94 and intra-observer between 0.40 and 0.94. Theoretical construct is supported in the literature. Factor analysis identifies three levels of GP inclusion: "difference by sex", "gender sensitive" and "feminist research" with an internal consistency of 0.64, 0.87 and 0.81, respectively, which explain 74.78% of variance. CONCLUSIONS: GPIHR questionnaire is a valid tool to assess GP and useful for those researchers who would like to include GP in their projects.

Syphilis in Men Who Have Sex With Men: A Warning Sign for HIV Infection.

OBJECTIVE: To describe the clinical and epidemiological characteristics of syphilis in men who have sex with men (MSM) in an area of Mallorca, Spain. METHODS: We performed a retrospective analysis of syphilis cases in MSM seen at a hospital in Mallorca between January 2005 and June 2013. RESULTS: Fifty-five cases of syphilis were recorded in MSM during the study period (34.3% of all cases diagnosed), and 74.5% of these patients had human immunodeficiency virus (HIV) coinfection. The two diseases had been diagnosed simultaneously in 70.7% of this population. Patients with HIV coinfection had a median CD4 count of 456cells/µL (range, 29-979 cells/µL). Syphilis was diagnosed clinically in 49.1% of cases and by screening in the remaining 50.9%. The most common form of syphilis was late latent or indeterminate syphilis (41.9% of cases). In the group of men with syphilis, MSM had a higher risk of HIV infection. CONCLUSIONS: A majority of MSM with syphilis had HIV coinfection. HIV screening is therefore essential in this population and could even result in early diagnosis.
