RESUMEN
OBJECTIVES: We aimed to assess HIV symptoms from the perspective of both patients and HIV specialists and the impact of discontinuing antiretroviral treatment (ART) on symptomology. We gathered opinions from HIV specialists and people living with HIV about ideal ART parameters and treatment satisfaction. METHODS: Ex post-facto cross-sectional surveys were administered to 502 people living with HIV and 101 HIV clinicians in Spain (18 sites). RESULTS: The median age of participants with HIV was 43.2 years, 74.5% were male, and 91.6% had an undetectable viral load. The mean time since initiation of ART was 10.2 years. Between 54% and 67% of people living with HIV reported experiencing nervousness or anxiety, sadness, fatigue, sleep problems, or muscle/joint pain during the preceding 4 weeks. However, only 22%-27% of specialists acknowledged the presence of these symptoms. The most bothersome symptoms were related to mental health or the central nervous system. There were significant differences between the burden of symptoms reported by people living with HIV and those acknowledged by specialists. The symptoms that more frequently caused ART discontinuation were depression, dizziness, and sleep problems. Both people living with HIV and specialists prioritized ART efficacy and low toxicity, but their importance ratings differed for 5 of the 11 ART characteristics assessed. People living with HIV rated their satisfaction with ART at a mean (± standard deviation) of 8.9 ± 1.5 out of 10, whereas HIV specialists rated it lower, at 8.3 ± 0.7 (p < 0.001). CONCLUSIONS: Despite advances in HIV care and treatment, a large proportion of patients still experience symptoms. HIV specialists may not be fully aware of these. People living with HIV and HIV specialists are, overall, satisfied with ART. However, the importance they place on different ART characteristics may vary.

INTRODUCTION AND AIMS: Oropharyngeal dysphagia (OD) occurs in children with cerebral palsy. It is important to investigate its relationship with some variables, and the objective of this study was to identify factors associated with OD. MATERIALS AND METHODS: Case-control study in patients with cerebral palsy from 8months to 15years of age, from November 2018 to November 2019, approved by the Ethics Committee. The diagnosis of OD was made by videofluoroscopy when there was nasopharyngeal reflux, stagnation in the vallecular sinuses, in the piriformis sinuses, penetration, and aspiration. The independent variables were type of cerebral palsy, gross motor impairment classified into five levels, nutritional status and comorbidities. One case with OD was included and the next one without alterations in videofluoroscopy was control. The variables were compared with Chi square and Student's t. The association was measured with odds ratio. The confidence interval was 95%. RESULTS: Thirty patients with OD and 30without OD were studied. Sex, age, birth weight, and gestational age had a similar distribution in the two groups. From the data perceived by the mothers at the time of feeding, the greater frequency of the difficulty in the transfer of the food bolus in the group with OD showed a statistically significant difference (P<.001) and of the studied factors, the levelV of the gross motor involvement was associated with a higher frequency of OD. CONCLUSIONS: OD was associated with level V of gross motor involvement.

RESUMEN
We determine the prevalence and trends of open neural tube defects (ONTDs) during 1991 to 2019 at the "Dr. Juan I. Menchaca" Civil Hospital of Guadalajara (Mexico). Also, details of potential risks were obtained in 662 newborns, including those 143 patients with anencephaly and open spina bifida (OSB) classified as isolated (cases) and 519 controls. Data were analyzed using multivariable logistic regression. Among 267 201 live births during the study period, 336 were born with ONTDs, yielding an overall prevalence of 12.6 per 10 000. After folic acid (FA)-related programs began in Mexico (2003-2019), only OSB showed a decline of 20.6%. For anencephaly, associated risks included relatives with neural tube defects (NTDs) (adjusted odds ratio [aOR]: 67.9, 95% confidence interval [95% CI]: 11.3-409.8), pre-pregnancy body mass index (BMI) ≥25 kg/m2 (aOR: 2.6, 95% CI: 1.1-6.0), insufficient gestational weight gain (aOR: 3.0, 95% CI: 1.3-7.1), parity ≥4 (aOR: 3.2, 95% CI: 1.3-7.7), and exposure to analgesic/antipyretic drugs (aOR: 9.0; 95% CI: 2.5-33.0). For OSB, associated risks included consanguinity (aOR: 14.0, 95% CI: 3.5-55.9), relatives with NTDs (aOR: 22.4, 95% CI: 4.5-112.9), BMI ≥25 kg/m2 (aOR: 2.5, 95% CI: 1.6-4.2), insufficient gestational weight gain (aOR: 1.9, 95% CI: 1.1-3.1), and exposures to hyperthermia (aOR: 2.3, 95% CI: 1.2-4.3), common cold (aOR: 6.8, 95% CI: 3.6-12.7), and analgesic/antipyretic drugs (aOR: 3.6, 95% CI: 1.3-10.0). Our high rate probably results from exposures to preventable risks, most related to FA, indicating a need for strengthening existing FA-related programs in Mexico.

BACKGROUND: Intraoperative findings during gastroschisis surgery are the main predictor associated with increased mortality. The aim of our study was to determine the type of surgical findings associated with inpatient mortality in a cohort of patients with gastroschisis from a university hospital in Western Mexico. MATERIALS AND METHODS: Infants with surgically repaired gastroschisis during the period 2011-2017 at the Dr. Juan I. Menchaca Civil Hospital of Guadalajara (Guadalajara, Mexico) were studied. Data regarding demographics, perinatal history, and intraoperative findings were collected and compared according to whether they were nonsurvivors (cases) or survivors (controls) at hospital discharge. Data were analyzed using logistic regression, determining its adjusted odds ratio (aOR) and its respective 95% confidence intervals (95% CIs). The proper adjustment of the model was verified using the Hosmer and Lemeshow test. RESULTS: Ninety-four patients with gastroschisis were studied, of which 13 were nonsurvivors (13.8%), and 81 (86.2%) were survivors at hospital discharge. In the group of survivors, primary surgical closure was performed more frequently (P = 0.018), whereas staged reduction with a silo predominated in the group of nonsurvivors (P = 0.018), and an increased frequency of complex gastroschisis (0.0001). After logistic regression analysis, intraoperative findings associated with nonsurvival were severe bowel matting (aOR: 7.3; 95% CI: 1.2-44), and prolapse of the small intestine and large intestine, plus any other organ (aOR: 15.9; 95% CI: 1.1-219.6). CONCLUSIONS: Mortality in our cohort was high (13.8%) and was significantly associated with severe bowel matting, and the prolapse of the small and large intestines, plus any other organ.

Helminth infections cause considerable morbidity worldwide and may be frequently underdiagnosed especially in areas of lower endemicity. Patients may harbor latent infections that may become symptomatic years or decades after the initial exposure and timely diagnosis may be critical to prevent complications and improve outcomes. In this context, disease in special populations, such as immunosuppressed patients, may be of particular concern. Heightened awareness and recent diagnostic developments may contribute to the correct management of helminth infections in nonendemic regions. A review of the main helminth infections in travelers and migrants (strongyloidiasis, taeniasis-neurocysticercosis and schistosomiasis) is presented, focusing on epidemiology, developments in diagnosis, treatment and prevention.

BACKGROUND: The proteinuria selectivity index (PSI) can predict the response to prednisone in the primary nephrotic syndrome (PNS). OBJECTIVE: To determine the association of prednisone response with the PSI in patients with PNS. MATERIAL AND METHODS: With analytical cross-sectional design, pediatric patients with PNS were studied with at least six months of prior follow-up, at the Nuevo Hospital Civil de Guadalajara from 2014 to 2015. They were divided into poor response to prednisone (frequent relapses or resistance) and good response (habitual relapses). PSI was calculated with serum and urinary measurement of IgG and transferrin. Chi square and OR were used, with 95% CI. RESULTS: 67 patients with relapsing PNS were studied. The response to prednisone had been good in 33 (49.3%) and poor in 34 (50.7%). The PSI was ≤ 0.10 mg/mg in 23/67 (34.3%); 0.11-0.19 mg/mg in 15/67 (22.4%); and ≥ 0.20 mg/mg 29/67 (43.3%). 3/34 patients (8.8%) presented ≤ 0.1 mg/mg with poor response to prednisone and 20/33 presented good response (60.6%) (p < 0.001; OR: 0.6; 95% CI, 0.010-20). PSI between 0.11-0-19 mg/mg occurred in 8/34 patients (23%) with poor response to prednisone and in 7/33 with good response (21%). PSI ≥ 0.20 mg/mg resulted in 23/34 patients (67.6%) with poor response to the steroid and in 6/33 with good response (18.2%) (p < 0.001; OR: 9.4; 95% CI, 3.01-29.42). CONCLUSIONS: In children with PNS, a PSI ≥ 0.20 mg/mg was associated with a poor response to prednisone treatment and a PSI ≤ 0.10 mg/mg with a satisfactory response.
INTRODUCCIÓN: El índice de selectividad de proteinuria (ISP) puede predecir la respuesta a prednisona en el síndrome nefrótico primario (SNP). OBJETIVO: Determinar la asociación de la respuesta a prednisona con el ISP en pacientes con SNP. MATERIAL Y MÉTODOS: Con diseño transversal analítico, se estudiaron pacientes pediátricos con SNP en recaída con al menos 6 meses de seguimiento previo, en el Nuevo Hospital Civil de Guadalajara, de 2014 a 2015. Se dividieron en mala respuesta a prednisona (recaídas frecuentes o resistencia) y buena respuesta (recaídas habituales). El ISP se calculó con medición sérica y urinaria de IgG y transferrina. Se utilizaron la prueba de chi cuadrada y razones de momios (RM) con sus intervalos de confianza del 95% (IC 95%). RESULTADOS: Se estudiaron 67 pacientes con SNP en recaída. La respuesta a prednisona había sido buena en 33 (49.3%) y mala en 34 (50.7%). De los 67 pacientes, el ISP fue ≤ 0.10 mg/mg en 23 (34.3%), 0.11-0.19 mg/mg en 15 (22.4%) y ≥ 0.20 mg/mg en 29 (43.3%). De los 34 con mala respuesta, el ISP fue ≤ 0.1 mg/mg en 3 (8.8%); de los 33 con buena respuesta, el ISP fue ≤ 0.1 mg/mg en 20 (60.6%) (p < 0.001; RM: 0.6; IC 95%: 0.010-20). El ISP fue 0.110-19 mg/mg en 8 (23%) de los 34 pacientes con mala respuesta a prednisona y en 7 (21%) de los 33 con buena respuesta. El ISP fue ≥ 0.20 mg/mg en 23 (67.6%) de los 34 pacientes con mala respuesta al esteroide y en 6 (18.2%) de los 33 con buena respuesta (p < 0.001; RM: 9.4; IC 95%: 3.01-29.42). CONCLUSIONES: En los niños con SNP, un ISP ≥ 0.20 mg/mg se asoció con mala respuesta a prednisona y un ISP ≤ 0.10 mg/mg se asoció con respuesta satisfactoria.

BACKGROUND: Exposure to pets can be a predisposing factor in the development of certain diseases, including allergic diseases. OBJECTIVE: We analyzed the role that exposure to indoor dogs and cats plays in the prevalence of allergic diseases. METHODS: We examined the cross-sectional data of 1056 women and 936 men aged 15 to 18 years; these individuals were selected through stratified and cluster random sampling. We asked all participants about their exposure to indoor dogs and cats during the year that preceded our study. The prevalence of allergic diseases was determined through core questions taken from The International Study of Asthma and Allergies in Childhood questionnaire. RESULTS: The prevalence was 12.7% (95% CI: 11.3%-14.2%) for asthma, 9.0% (95% CI: 7.8%-10.4%) for allergic rhinitis, and 5.2% (95% CI: 4.3%-6.2%) for atopic dermatitis. The multivariate analyses showed that exposure to indoor dogs, but not indoor cats, was associated with asthma prevalence (aOR 1.37; 95% CI: 1.03-1.83), as was male sex (aOR=1.42; 95% CI: 1.08-1.86), a personal history of allergic rhinitis (aOR=3.24; 95% CI: 2.25-4.66), and a maternal history of asthma (aOR=3.06; 95% CI: 1.89-4.98). The population attributable risk for exposure to indoor dogs was 18%. Notably, neither allergic rhinitis nor atopic dermatitis was found to be associated with dog or cat exposure (p> 0.05). CONCLUSION: Exposure to dogs in late adolescence is a factor associated with asthma, although its contribution to the development of asthma should be investigated in new studies.

OBJECTIVES: Chagas disease (CD) treatment is limited to two therapeutic options: benznidazole (generally the first option in Spain) and nifurtimox. Both drugs present high rates of adverse reactions and treatment discontinuation and there is no consensus regarding the most effective administration schedule for benznidazole or how to prevent and manage treatment toxicity. We aim to compare the tolerability and treatment discontinuation rate between two different treatment schemes with benznidazole. METHODS: This was a prospective observational study of adult patients with CD, enrolled from January 2014 to March 2018 in two referral centres in Madrid (Spain). Participants were treated either with benznidazole 5 mg/kg/day (full dose) over 60 days (benznidazole standard dose scheme (BSD)), or with an escalating dose lasting 5 days up to a maximum of 300 mg/day (benznidazole increasing dose scheme (BID)). RESULTS: 471 patients were analysed: 201 in the BSD group and 270 in the BID group. There were no significant differences regarding age (40.4 (SD 8.7) vs 41 (SD 8.2) years), sex (74.1% (149/201) vs 68.5% (185/270) women), weight (69.4 (SD 12.8) vs 68.9 (SD 11) kg) or nationality (97.5% (196/201) vs 96.7% (261/270) Bolivians) between groups. There were also no differences in adverse reactions rate (55.2% (111/201) vs 55.6% (150/270)), number of adverse reactions per patient, adverse reactions type (except for arthralgias and myalgias which occurred more frequently in the BID group (0% (0/111) BSD vs 8% (12/150) BID; p 0.002)) and degree and time to first adverse reactions. There was significantly more treatment discontinuation (49.8% (100/201) vs 33.0% (89/270); p <0.001) in the BSD group, but not during the first 30 days of treatment (32.3% (65/201) vs 25.6% (69/270); p 0.08). CONCLUSION: The use of increasing doses of benznidazole for 5 days and a maximum dose of 300 mg, does not significantly improve drug tolerability. However, while the treatment discontinuation rates were similar during the first 30 days of treatment, it may improve the treatment completion rate at 60 days.

Resumen Introducción Los pacientes con diabetes mellitus tipo 1 (DM1) y sobrepeso tienen más riesgo de desarrollar cambios en la presión arterial (PA), y esto incrementa su morbilidad y mortalidad cardiovascular. En este estudio se determinó la relación entre la PA y el índice de masa corporal (IMC) y el promedio de las tres últimas mediciones de hemoglobina glucosilada (HbA1c) de pacientes con DM1. Métodos Estudio transversal analítico en niños y adolescentes con DM1 con más de un año de evolución. Las variables dependientes fueron la PA sistólica y diastólica medidas con esfigmomanómetro y las variables independientes, IMC y promedio de las últimas tres mediciones de la HbA1c. Se utilizó regresión lineal múltiple con intervalo de confianza del 95%. Resultados Se estudiaron 75 pacientes con DM1. La mediana del tiempo de evolución de la DM1 fue de 3.5 años (mínimo 1 año-máximo 14.8 años), el IMC 19.5 ± 3.1 kg/cm2 y la HbA1c 8.3 ± 2.4%. De los 75 pacientes, 66 presentaron PA < percentil 90 y 9 PA ≥ percentil 90 (12%). Se construyeron dos modelos de regresión lineal múltiple, con PA sistólica y diastólica como variables dependientes. Las posibles variables predictoras fueron sugeridas por el contexto teórico y el análisis estadístico. El IMC expresado en puntuación zeta (zIMC) fue predictor para PA sistólica/diastólica. Los modelos sugirieron que a cada incremento de unidad del zIMC corresponde un aumento de 5.1 y 3.6 mmHg de PA sistólica y diastólica, respectivamente. Conclusiones Se observó una correlación positiva de la PA sistólica y la diastólica con el zIMC.
Abstract Background Patients with type 1 diabetes mellitus (T1DM) and overweight have more risk to develop changes in blood pressure that increase cardiovascular morbidity and mortality. In this study, the relationship between blood pressure (BP) with the body mass index (BMI) and the average of the last three measurements of glycated hemoglobin (HbA1c) in patients with T1DM was determined. Methods A cross-sectional analytical study was conducted in children and adolescents with T1DM with over a year since diagnosis. The dependent variables were systolic and diastolic BP, measured with a mercury sphygmomanometer. The independent variables were BMI and average of the last three measurements of HbA1. A linear regression with a 95% confidence interval was used. Results Seventy-five patients with T1DM were studied. The median of disease duration was 3.5 years (min 1-max 14.8 years), BMI 19.5 ± 3.1 kg/cm2 and HbA1c 8.3 ± 2.4%. Sixty-six patients showed BP < percentile 90 and 9 BP ≥ percentile 90 (12%). Two models of linear regression were constructed, with systolic and diastolic BP as dependent variables. The possible predictor variables were suggested by theoretical context and statistical analysis. The predictive variable of high BP was zBMI (body mass index expressed in z-score) for systolic and diastolic BP. Also, the models suggested that for an increase of one unit of zBMI, corresponded a rise of 5.1 and 3.6 mmHg in systolic and diastolic BP, respectively. Conclusions A positive correlation between systolic and diastolic BP with zBMI was observed.

INTRODUCTION: Substances related to microorganisms involved in periodontal disease can reach the maternal-fetal interface via the hematogenous route and stimulate uterine contractility. OBJECTIVE: To determine the association between periodontal disease and preterm birth. METHOD: Case-control study in 343 preterm and 686 full-term pregnant women. Gestational age was calculated based on the date of the last menstrual period and confirmed with Capurro and Ballard methods. Periodontal disease was diagnosed according to the depth of the space between the tooth root and the gum. The association was measured with logistic regression. RESULTS: Maternal age of the cases was 23.8 ± 6.7 years, and 23.2 ± 6.7 in the controls. Periodontal disease was present in 66.8% of cases and 40.5% of controls. The factors associated with preterm birth were periodontal disease (Odds ratio [OR] = 2.26), history of preterm birth (OR = 4.96), unplanned pregnancy (OR = 2.15) poor prenatal control (OR = 2.53), urinary tract infection (OR = 2.22), preeclampsia (OR = 4.49), premature rupture of membranes (OR = 2.59) and caesarean section delivery (OR = 9.15). CONCLUSION: Periodontal disease in pregnancy was an independent risk factor for preterm birth.
INTRODUCCIÓN: Las sustancias relacionadas con los microorganismos involucrados en la enfermedad periodontal puedan llegar a la interfaz materno-fetal por vía hematógena y estimular la contractilidad uterina. OBJETIVO: Determinar la asociación entre enfermedad periodontal con nacimiento pretérmino. MÉTODO: Estudio de casos y controles de 343 embarazadas pretérmino y 686 de término. Se calculó la edad gestacional por fecha de último periodo menstrual y se confirmó con los métodos de Capurro y Ballard. La enfermedad periodontal se diagnosticó por la profundidad del espacio entre la raíz dental y la encía. La asociación fue medida con regresión logística. RESULTADOS: La edad de las madres en los casos fue de 23.8 ± 6.7 años y en los controles de 23.2 ± 6.7 años. La enfermedad periodontal estuvo presente en 66.8 % de los casos y 40.5 % de los controles. Los factores asociados con nacimiento pretérmino fueron enfermedad periodontal (RM = 2.26), antecedente de nacimiento pretérmino (RM = 4.96), embarazo no planeado (RM = 2.15), control prenatal deficiente (RM = 2.53), infección de vías urinarias (RM = 2.22), preeclampsia (RM = 4.49), ruptura prematura de membranas amnióticas (RM = 2.59) y nacer por cesárea (RM = 9.15).

Resumen Introducción: Las sustancias relacionadas con los microorganismos involucrados en la enfermedad periodontal puedan llegar a la interfaz materno-fetal por vía hematógena y estimular la contractilidad uterina. Objetivo: Determinar la asociación entre enfermedad periodontal con nacimiento pretérmino. Método: Estudio de casos y controles de 343 embarazadas pretérmino y 686 de término. Se calculó la edad gestacional por fecha de último periodo menstrual y se confirmó con los métodos de Capurro y Ballard. La enfermedad periodontal se diagnosticó por la profundidad del espacio entre la raíz dental y la encía. La asociación fue medida con regresión logística. Resultados: La edad de las madres en los casos fue de 23.8 ± 6.7 años y en los controles de 23.2 ± 6.7 años. La enfermedad periodontal estuvo presente en 66.8 % de los casos y 40.5 % de los controles. Los factores asociados con nacimiento pretérmino fueron enfermedad periodontal (RM = 2.26), antecedente de nacimiento pretérmino (RM = 4.96), embarazo no planeado (RM = 2.15), control prenatal deficiente (RM = 2.53), infección de vías urinarias (RM = 2.22), preeclampsia (RM = 4.49), ruptura prematura de membranas amnióticas (RM = 2.59) y nacer por cesárea (RM = 9.15). Conclusión: La enfermedad periodontal en el embarazo constituyó un factor de riesgo independiente para nacimiento pretérmino.
Abstract Introduction: Substances related to microorganisms involved in periodontal disease can reach the maternal-fetal interface via the hematogenous route and stimulate uterine contractility. Objective: To determine the association between periodontal disease and preterm birth. Method: Case-control study in 343 preterm and 686 full-term pregnant women. Gestational age was calculated based on the date of the last menstrual period and confirmed with Capurro and Ballard methods. Periodontal disease was diagnosed according to the depth of the space between the tooth root and the gum. The association was measured with logistic regression. Results: Maternal age of the cases was 23.8 ± 6.7 years, and 23.2 ± 6.7 in the controls. Periodontal disease was present in 66.8% of cases and 40.5% of controls. The factors associated with preterm birth were periodontal disease (Odds ratio [OR] = 2.26), history of preterm birth (OR = 4.96), unplanned pregnancy (OR = 2.15) poor prenatal control (OR = 2.53), urinary tract infection (OR = 2.22), preeclampsia (OR = 4.49), premature rupture of membranes (OR = 2.59) and caesarean section delivery (OR = 9.15). Conclusion: Periodontal disease in pregnancy was an independent risk factor for preterm birth.

Background: Dual therapy (DT) with a ritonavir-boosted PI (PI/r) plus lamivudine has proven non-inferior (12% margin) to triple therapy (TT) with PI/r plus two nucleos(t)ide reverse transcriptase inhibitors [N(t)RTIs] in four clinical trials. It remains unclear whether DT is non-inferior based on the US FDA endpoint (virological failure with a margin of 4%) or in specific subgroups. Methods: We performed a systematic search (January 1990 to March 2017) of randomized controlled trials that compared switching of maintenance ART from TT to DT. The principal investigators were contacted and agreed to share study databases. The primary endpoint was non-inferiority of DT to TT based on the current FDA endpoint (4% non-inferiority margin for virological failure at week 48). We also analysed whether efficacy was modified by gender, active HCV infection and type of PI. Effect estimates and 95% CIs were calculated using generalized estimating equation-based models. Results: We found 881 references that yielded eight articles corresponding to four clinical trials (1051 patients). At week 48, 4% of patients on DT versus 3.04% on TT had experienced virological failure (difference 0.9%; 95% CI -1.2% to 3.1%), and 84.7% of patients on DT versus 83.2% on TT had <50 copies of HIV RNA/mL (FDA snapshot algorithm) (difference 1.4%; 95% CI -2.8% to 5.8%). Gender, active HCV infection and type of PI had no effect on differences in treatment efficacy between DT and TT. Conclusions: DT was non-inferior to TT using both current and past FDA endpoints. The efficacy of DT was not influenced by gender, active HCV infection status, or type of PI.

OBJECTIVE: To describe the tolerability and rate of nifurtimox discontinuation when administered as a second-line treatment to patients with previous treatment interruptions due to adverse reactions with benznidazole. METHODS: We studied a prospective cohort study of adult patients with chronic Chagas disease in a referral centre in Spain treated from July 2007 to July 2017. We analysed the tolerability profile and treatment interruption rate due to adverse reactions (ARs) to nifurtimox in patients previously incompletely treated (less than 30 days) with benznidazole due to ARs. RESULTS: A total of 472 patients initiated treatment with benznidazole during the study period. Of these, 118 (25%) developed ARs that led to treatment discontinuation before 30 days of therapy. Fifty-three (44.9%) of 118 initiated nifurtimox as second-line treatment; most were women (79.3%), were of Bolivian origin (98.1%) and had a median age of 37.3 years (interquartile range, 29.8-43.2). The most common ARs with nifurtimox were cutaneous hypersensitivity (24.1%), digestive disorders (22.2%), fever (12.9%), neurologic disturbances (11.1%), depression, anxiety or insomnia (9.2%), dyspnoea (7.4%), myalgia (5.5%), and dizziness, asthenia or malaise (7.4%). Twenty-six (49.1%) of 53 patients discontinued nifurtimox due to ARs, all of them before the required minimal therapy duration of 60 days. There were no deaths. CONCLUSIONS: Treatment of chronic Chagas disease relies on two drugs with a poor tolerability profile. In our cohort, 12.3% of the patients who initiated benznidazole and subsequently nifurtimox in case of nontolerance developed ARs that led to permanent treatment discontinuation. Most were women of childbearing age, a group for whom therapy has the added benefit of interrupting vertical transmission.

We determined the overall prevalence of typical orofacial clefts and the potential risks for nonsyndromic cleft lip with or without cleft palate in a university hospital from West México. For the prevalence, 227 liveborn infants with typical orofacial clefts were included from a total of 81,193 births occurred during the period 2009-2016 at the "Dr. Juan I. Menchaca" Civil Hospital of Guadalajara (Guadalajara, Jalisco, Mexico). To evaluate potential risks, a case-control study was conducted among 420 newborns, including only those 105 patients with nonsyndromic cleft lip with or without cleft palate (cases), and 315 infants without birth defects (controls). Data were analyzed using multivariable logistic regression analysis expressed as adjusted odds ratio with 95% confidence intervals . The overall prevalence for typical orofacial clefts was 28 per 10,000 (95% confidence interval: 24.3-31.6), or 1 per 358 live births. The mean values for the prepregnancy weight, antepartum weight, and pre-pregnancy body mass index were statistically higher among the mothers of cases. Infants with nonsyndromic cleft lip with or without cleft palate had a significantly higher risk for previous history of any type of congenital anomaly (adjusted odds ratio: 2.7; 95% confidence interval: 1.4-5.1), history of a relative with cleft lip with or without cleft palate (adjusted odds ratio: 19.6; 95% confidence interval: 8.2-47.1), and first-trimester exposures to progestogens (adjusted odds ratio: 6.8; 95% CI 1.8-25.3), hyperthermia (adjusted odds ratio: 3.4; 95% confidence interval: 1.1-10.6), and common cold (adjusted odds ratio: 3.6; 95% confidence interval: 1.1-11.9). These risks could have contributed to explain the high prevalence of orofacial clefts in our region of Mexico, emphasizing that except for history of relatives with cleft lip with or without cleft palate, most are susceptible of modification.

INTRODUCTION: The commonly held notion that a rural environment decreases the frequency of allergic diseases has proven to be inconsistent amongst children. OBJECTIVE: Our objective was to contrast the prevalence of bronchial asthma (BA), allergic rhinitis (AR), and atopic dermatitis (AD) between children that live in a rural environment and those that live in urban areas. METHODS: We carried out a cross-sectional study amongst children aged six to seven; they were selected through probabilistic, stratified and conglomerated sampling. The prevalence of BA, AR, and AD was identified with the use of the questionnaire provided by The International Study of Asthma and Allergies in Childhood, additionally, we inquired about each child's family history of atopy, their exposure to farm animals, the intake of unpasteurised cow's milk, and the number of siblings related to every child. We used logistic regression and multivariate analysis to determine the correlation between asthma, allergic diseases, and rural environment. RESULTS: We included 189/1003 (18.8%) children from a rural environment, and 814/1003 (81.2%) from an urban area. BA and AR were associated to a family history of atopy (OR=2.15, p=0.001; OR=2.58, p=0.002, respectively). BA was more prevalent in males (OR=1.92, p=0.007). Notably, a higher number of siblings seems to protect against AR (OR=0.45, p=0.008). A paternal history of allergies was associated to AD. CONCLUSIONS: In our study, we were unable to find protective factors in a rural environment that might decrease the prevalence of asthma or allergic diseases.

OBJECTIVES: We evaluated whether maintenance therapy with atazanavir/ritonavir plus lamivudine (ATV/râ+â3TC) was non-inferior to ATV/r plus two nucleosides (ATV/râ+â2NUCs) at 96 weeks of follow-up. METHODS: SALT is a multicentre, open-label, non-inferiority clinical trial in HIV-1-infected virologically suppressed patients. Hepatitis B virus surface antigen-negative subjects with no previous treatment failure/resistance mutations and HIV-1-RNA <50 copies/mL for ≥6 months were randomized (1â:â1) to ATV/râ+â3TC or ATV/râ+â2NUCs. The primary endpoint was HIV-1-RNA <50 copies/mL in the PP population. Non-inferiority was demonstrated if the lower bound of the 95% CI for the difference was not below -12%. RESULTS: Some 286 patients were analysed. At week 96, 74.4% had HIV-1-RNA <50 copies/mL in the ATV/râ+â3TC arm versus 73.9% in the ATV/râ+â2NUCs arm (95% CI for the difference, -9.9%-11.0%). In both groups, similar values were observed for patients with confirmed virological failure in ATV/râ+â3TC versus ATV/râ+â2NUCs (9 versus 5), death (1 versus 0), discontinuation due to ART-related toxicity (7 versus 11), withdrawal from the study (7 versus 9) and loss to follow-up (6 versus 6). One patient taking ATV/râ+â2NUCs developed resistance mutations (M184V and L63P). Similar values were obtained for change in mean CD4 count [19 versus 18 cells/mm3 (95% CI for the difference, -49.3-50.7), grade 3-4 adverse events (70.7% versus 70.2%) and changes in the global deficit score, -0.3 (95% CI, -0.5 to -0.1) for ATV/râ+â3TC, versus -0.2 (95% CI, -0.4 to -0.1) for ATV/râ+â2NUCs]. CONCLUSIONS: The long-term results of switching to ATV/râ+â3TC show that this strategy is effective, safe and non-inferior to ATVâ+â2NUCs in virologically suppressed HIV-infected patients.

OBJECTIVES: International health agencies have promoted nontargeted universal (opt-out) HIV screening tests in different settings, including emergency departments (EDs). We performed a systematic review and meta-analysis to assess the testing uptake of strategies (opt-in targeted, opt-in nontargeted and opt-out) to detect new cases of HIV infection in EDs. METHODS: We searched the Pubmed and Embase databases, from 1984 to April 2015, for opt-in and opt-out HIV diagnostic strategies used in EDs. Randomized controlled or quasi experimental studies were included. We assessed the percentage of positive individuals tested for HIV infection in each programme (opt-in and opt-out strategies). The mean percentage was estimated by combining studies in a random-effect meta-analysis. The percentages of individuals tested in the programmes were compared in a random-effect meta-regression model. Data were analysed using stata version 12. Quality assessments were performed using the Newcastle-Ottawa Scale. RESULTS: Of the 90 papers identified, 28 were eligible for inclusion. Eight trials used opt-out, 18 trials used opt-in, and two trials used both to detect new cases of HIV infection. The test was accepted and taken by 75 155 of 172 237 patients (44%) in the opt-out strategy, and 73 581 of 382 992 patients (19%) in the opt-in strategy. The prevalence of HIV infection detected by the opt-out strategy was 0.40% (373 cases), that detected by the opt-in nontargeted strategy was 0.52% (419 cases), and that detected by the opt-in targeted strategy was 1.06% (52 cases). CONCLUSIONS: In this meta-analysis, the testing uptake of the opt-out strategy was not different from that of the opt-in strategy to detect new cases of HIV infection in EDs.
