Introduction: Varicocele is the abnormal dilatation of the pampiniform plexus. It occurs in 15-20% of pre-adolescent/adult males.Varicocele diagnosis is important since it can induce testicular hyper-trophy and fertility issues in adulthood. The objective of this studywas to assess whether complications, including varicocele recurrence,depend on the vascular occlusion technique used –clipping + divisionvs. vascular sealer–in the laparoscopic Palomo technique used inour institution. Materials and methods: A longitudinal, prospective study wascarried out from 2017 to 2021. Two therapeutic groups were createdaccording to the vascular occlusion method used during laparoscopicvaricocelectomy –clipping + division vs. vascular sealer. Patients wererandomly allocated to the groups in a systematic alternating consecutivemanner. Variables –age, varicocele grade according to the Dubin-Amelarclassification, postoperative complications, follow-up, and varicocelerecurrence– were analyzed according to the method employed.Results: A total of 37 boys, with a mean age of 12 years (10-15years) and a mean follow-up of 12 months, were studied. In 20 patients (54.1%), clipping + division was used, and in the remaining 17(45.9%), the vascular sealer was employed. 24.3% had symptomaticGrade II varicocele and 75.7% had Grade III varicocele. 32.4% of thechildren had postoperative complications during follow-up. 29.7% ofthe patients had hydrocele following surgery –8 boys from the seal-ing group and 3 boys from the clipping group–, with 13.5% requiringre-intervention as a result of this.

Varicocele diagnosis is important since it can induce testicular hypertrophy and fertility issues in adulthood. The objective of this study was to assess whether complications, including varicocele recurrence, depend on the vascular occlusion technique used -clipping + division vs. vascular sealer- in the laparoscopic Palomo technique used in our institution. MATERIALS AND METHODS: A longitudinal, prospective study was carried out from 2017 to 2021. Two therapeutic groups were created according to the vascular occlusion method used during laparoscopic varicocelectomy -clipping + division vs. vascular sealer. Patients were randomly allocated to the groups in a systematic alternating consecutive manner. Variables -age, varicocele grade according to the Dubin-Amelar classification, postoperative complications, follow-up, and varicocele recurrence- were analyzed according to the method employed. RESULTS: A total of 37 boys, with a mean age of 12 years (10-15 years) and a mean follow-up of 12 months, were studied. In 20 patients (54.1%), clipping + division was used, and in the remaining 17 (45.9%), the vascular sealer was employed. 24.3% had symptomatic Grade II varicocele and 75.7% had Grade III varicocele. 32.4% of the children had postoperative complications during follow-up. 29.7% of the patients had hydrocele following surgery -8 boys from the sealing group and 3 boys from the clipping group-, with 13.5% requiring re-intervention as a result of this. None of the patients had varicocele recurrence. CONCLUSIONS: The laparoscopic Palomo technique is safe and effective, with good results in pediatric patients and few postoperative complications, regardless of the vascular occlusion device used. In our study, no statistically significant differences regarding the use of clipping or vascular sealer in this laparoscopic technique were found. However, further studies with a larger sample size are required to find potential differences.

No obstante, es preciso realizar más estudios con mayor tamaño muestral para hallar posibles diferencias.

Effect in variation of the cationic precursor temperature on the electrical and crystalline properties of MnS growth by SILAR.

The crystallographic, optical, and electrical properties of manganese sulfide thin films depend on the control of the temperature precursors in the synthesis process, as shown by the results of this work. MnS thin films were deposited on glass substrates using the SILAR method and over an additional layer of CdS synthesized by chemical bath deposition (CBD) to acquire a p-n heterojunction. SILAR is an inexpensive method performed with a homemade robot in this case. Temperature in the solution precursors varied from 20 to 80 °C in four experiments. The morphology and structure of MnS and FTO/CdS/MnS thin films were studied through scanning electron microscopy (SEM) and grazing-incidence X-ray diffraction (GIXRD); the results indicate that materials showed a polycrystalline behavior, a diffraction peak of α- MnS cubic phase was observed with lattice constants values, ranging from 4.74 to 4.75 Å. Additionally, Raman spectroscopy showed a signal corresponding to the transversal optical phonons of MnS at a wavenumber near 300 cm-1. UV-vis spectroscopy showed optical bandgap values of 3.94, 4.0, 4.09, and 4.26 eV for thin films obtained at 20°, 40°, 60°, and 80 °C. respectively. Results indicated 80 °C as an optimal cationic precursor process temperature, achieving optical transmittance T% and good film quality according to SEM and GIXRD for the synthetization of MnS. The current-voltage (I-V) characterization in the heterojunction showed a characteristic diode curve with an open circuit voltage (VOC) of 300 mV under illumination, which indicated that the manganese sulfide behaves as p-type material contributing with positive charge carriers, while CdS behaves as n-type material.

Inactivation of isolated fungi on Erythrina velutina Willd. seeds through atmospheric plasma

Abstract This study aimed to evaluate the effect of atmospheric plasma application on the inactivation of fungi on the surface of Erythrina velutina seeds and on isolated fungal colonies. Two experiments were conducted using a completely randomized design. First, plasma was applied to the surface of the seeds using helium gas and atmospheric plasma for 3, 6, and 9 min in addition to the control (untreated seeds), constituting seven treatments with five repetitions each. In the second experiment, Petri dishes containing the inoculum of different fungi were treated with atmospheric air plasma for 3, 6, and 9 min (Air-3, Air-6, and Air-9) and were compared with untreated fungi in Petri dishes without treatment (control), totaling four treatments and five repetitions each. We found that the application of atmospheric air plasma to E. velutina seeds for 9 min had an antimicrobial effect on the fungi Aspergillus niger, Aspergillus flavus, Fusarium sp., Brachysporium sp., and Rhizopus sp. The formation of fungal colonies isolated from E. velutina seeds was also inhibited by 3 min of exposure to atmospheric air plasma, except for A. niger, whose inhibition occurred after 6 min of exposure to atmospheric plasma.

Resumo Este trabalho teve como objetivo avaliar o efeito da aplicação de plasma atmosférico na inativação de fungos na superfície de sementes de Erythrina velutina e em colônias fúngicas isoladas. Dois experimentos foram realizados em delineamento inteiramente casualizado: no primeiro, o plasma foi aplicado na superfície das sementes usando gás hélio e plasma atmosférico por três, seis e nove minutos, além do controle (sementes sem tratamento), constituindo sete tratamentos com cinco repetições cada; no segundo experimento, placas de Petri contendo o inóculo de diferentes fungos foram tratadas com plasma atmosférico por três, seis e nove minutos (Air-3, Air-6 e Air-9) e comparadas com fungos não tratados em placas de Petri sem tratamento (controle), totalizando quatro tratamentos e cinco repetições cada. Descobrimos que a aplicação de plasma atmosférico nas sementes de E. velutina por nove minutos teve efeito antimicrobiano sobre os fungos Aspergillus niger, Aspergillus flavus, Fusarium sp., Brachysporium sp. e Rhizopus sp. A formação de colônias fúngicas isoladas de sementes de E. velutina também foi inibida por três minutos de exposição à aplicação de plasma atmosférico, exceto para A. niger, cuja inibição ocorreu a partir de 6 minutos de exposição à aplicação de plasma atmosférico.

Pre-germination treatments of melon seeds for the production of seedlings irrigated with biosaline water

Abstract Melon production in the Brazilian semi-arid region is subject to the use of marginal waters with high salinity. However, the use of regulators and bioactivators in seed treatment can mitigate the harmful effects of salts in irrigation water. In this context, the objective was to evaluate the effect of pre-germination treatments with plant regulators and bioactivator in melon seeds for the production of seedlings irrigated with biosaline water from fish farming effluent. For this, two trials with the Goldex and Grand Prix hybrids were carried out separately. A completely randomized design was used in a 4 × 3 factorial scheme (pre-germination treatments × water dilutions). In addition to the control, the seeds were treated with salicylic and gibberellic acids and thiamethoxam. The waters used for irrigation were local-supply water, fish farming effluent (biosaline water) and these diluted to 50%. Physiological and biochemical analyses were performed for fourteen days. Biosaline water (5.0 dS m-1) did not affect the emergence of Goldex melon seedlings, but compromised the establishment of the Grand Prix cultivar. Seed pre-treatments with salicylic and gibberellic acids attenuate the effects of water salinity and promote growth modulations, resulting in more vigorous melon seedlings.

Resumo A produção de meloeiro no semiárido brasileiro está sujeita a utilização de águas marginais com salinidade elevada. Entretanto, a utilização de reguladores e bioativadores no tratamento de sementes podem mitigar os efeitos nocivos dos sais na água de irrigação. Nesse sentido, objetivou-se avaliar o efeito de tratamentos pré-germinativos com fitorreguladores e bioativador em sementes de melão para a produção de mudas irrigadas com água biossalina de efluente de piscicultura. Para isso, dois ensaios com os híbridos Goldex e Grand Prix foram realizados separadamente. Utilizou-se delineamento inteiramente casualizado em esquema fatorial 4 × 3 (tratamentos pré-germinativos × diluições de água). Além do controle, as sementes foram tratadas com os ácidos salicílico e giberélico, e tiametoxam. As águas utilizadas para irrigação foram a de abastecimento local, efluente de piscicultura (água biossalina) e estas diluídas a 50%. Durante quatorze dias foram realizadas as análises fisiológicas e bioquímicas. A água biossalina (5,0 dS m-1) não afetou a emergência de plântulas de meloeiro Goldex, mas prejudicou o estabelecimento da cultivar Grand Prix. Os pré-tratamentos de sementes com os ácidos salicílico e giberélico atenuam os efeitos da salinidade da água e promovem modulações no crescimento, proporcionando mudas de meloeiro mais vigorosas.

Eficacia del tratamiento de rehabilitación para el síndrome del túnel carpiano: un ensayo clínico controlado aleatorizado / Efficacy of rehabilitation treatment for carpal tunnel syndrome: A randomized controlled clinical trial

Introducción y objetivo El síndrome del túnel carpiano es la neuropatía del nervio mediano más frecuente. Existen múltiples tratamientos invasivos y no invasivos, incluyen férulas, ultrasonido terapéutico (UST) e infiltraciones con esteroides (IE) que han demostrado una mejora en los estudios de conducción nerviosa (ECN), sin embargo, se desconoce el efecto de los tratamientos conservadores combinados. El objetivo fue determinar la eficacia del tratamiento conservador para mejorar los ECN y las manifestaciones clínicas en pacientes con síndrome del túnel carpiano. Métodos Pacientes con diagnóstico de síndrome del túnel carpiano mediante ECN, sin enfermedades que afecten al nervio periférico. Todos firmaron consentimiento informado y fueron aleatorizados en 3 grupos de tratamiento (G1: férula+UST; G2: férula+IE; G3; férula+UST+IE). Participaron 3 médicos especialistas en rehabilitación (médico 1: realizó los ECN; médico 2: realizó evaluaciones clínicas; médico 3: realizó la IE). Tratamientos: UST (10 sesiones continuas de lunes a viernes durante dos semanas, 3MHz, 0,8W/cm2, 8min) aplicado por el mismo fisioterapeuta. Infiltración: dosis única, 1ml de metilprednisolona (40mg/ml) mezclado con 1ml de (0,5%) bupivacaína. Férula: férulas neutras volares hechas a la medida, de fibra de vidrio para uso nocturno. Resultados Se incluyeron 30 pacientes y 30 manos, con una edad de 50,5±7,5 años, todas ellas mujeres. Los grupos no tenían diferencias en las variables electrofisiológicas y clínicas al inicio del estudio. Tras la intervención (4 semanas) los grupos 2 y 3 mostraron mejoría en el ECN (p<0,05) siendo mayor en el grupo 3. En la evaluación final (8 semanas) todos los grupos mostraron una mejoría en las variables electrofisiológicas y clínicas. Conclusiones El tratamiento combinado de férula+UST+IE presenta resultados significativos en el ECN a las 4 semanas de seguimiento, en comparación a los otros dos grupos (AU)

Introduction and objective Carpal tunnel syndrome is the most common median nerve mononeuropathy. There are multiple conservative treatments, invasive (corticoid injections [CI]) and non-invasive (splinting, therapeutic ultrasound [TUS], laser, exercise). However, the treatment choice is controversial. The aim was to determine the efficacy of conservative treatment to improve the clinical and electrophysiological evaluations. Methods Outpatients referred whit carpal tunnel syndrome clinical diagnosis to perform nerve conduction study (NCS) were included, without chronic or metabolic diseases that affect the peripheral nerves, without carpal tunnel syndrome treatment and with mild or moderate axonotmesis or neuropraxia in NCS baseline. Patients who signed informed consent forms were randomized in three treatment groups (Group 1: TUS+splint; Group 2: CI+splint and Group 3: TUS+CI+splint) were referred for clinical evaluations. The NCS was performed in each patient at baseline, fourth and eighth weeks by the same physiatrist and the clinical evaluations were performed at baseline and the final follow-up. Results Thirty patients were included; mean age was 50.7±7.5 years and all of them females, without differences in NCS or clinical variables in the baseline evaluations. All groups exhibited improvement in some clinical and electrophysiological variables in the final evaluation, though only group 3 showed improvement on median/ulnar nerves sensory peak latency difference (1.2±0.4 vs. 0.4±0.4; p=0.001) starting in week four. Conclusions The conservative treatment in patients with CTS improves NCS and clinical variables, including the most sensitive electrophysiological test (medial/ulnar difference), though if we combined three treatments (splint+TUS+CI), the improvement was found to be faster and remarkable (AU)

The feasibility of a multidomain dementia risk reduction randomised controlled trial for people experiencing cognitive decline: the Body, Brain, Life for Cognitive Decline (BBL-CD).

OBJECTIVES: To evaluate the feasibility of a proof-of-concept multidomain dementia risk reduction intervention. METHOD: An 8-week, parallel-group RCT, focused on increasing adherence to lifestyle domains of Mediterranean diet (MeDi), Physical Activity (PA), and Cognitive Engagement (CE). Feasibility was evaluated against the Bowen Feasibility Framework objectives of: Acceptability of the intervention, compliance with the protocol, and efficacy of the intervention to change behaviour in the three domains of interest. RESULTS: High acceptability of the intervention was demonstrated through a participant retention rate of 80.7% (Intervention: 84.2%; Control: 77.4%). Compliance to the protocol was strong with 100% of participants completing all educational modules and all MeDi and PA components, with 20% compliance for CE. Linear mixed models demonstrated efficacy to change behaviour through significant effects of adherence to MeDi (χ2 = 16.75, df = 3, p < .001) and CE (χ2 = 9.83, df = 3, p =.020), but not PA (χ2 = 4.48, df = 3, p =.211). CONCLUSION: Overall the intervention was shown to be feasible. Recommendations for future trials in this area are: The implementation of practical, one-on-one sessions as they are more effective than passive education at eliciting behaviour change; use of booster sessions to increase likelihood of lifestyle changes being sustained; and collection of qualitative data to identify barriers to change.

[Translated article] One-year mortality and associated factors in patients undergoing surgery for hip fracture.

INTRODUCTION: Hip fractures are very common injuries in elderly patients and are associated with increased mortality. OBJECTIVE: To identify the factors associated with mortality in patients after one year of being operated for hip fracture in an Orthogeriatric Program. METHODS: We design an observational analytical study in subjects older than 65 years admitted to the Hospital Universitario San Ignacio for hip fracture who were treated in the Orthogeriatrics Program. Telephone follow-up was performed one year after admission. Data were analyzed using a univariate logistic regression model and a multivariate logistic regression model was applied to control the effect of the other variables. RESULTS: Mortality was 17.82%, functional impairment was 50.91%, and institutionalization was 13.9%. The factors associated with mortality were moderate dependence (OR=3.56, 95% CI=1.17-10.84, p=0.025), malnutrition (OR=3.42, 95% CI=1.06-11.04, p=0.039), in-hospital complications (OR=2.80, 95% CI=1.11-7.04, p=0.028), and older age (OR=1.09, 95% CI=1.03-1.15, p=0.002). The factor associated with functional impairment was a greater dependence at admission (OR=2.05, 95% CI=1.02-4.10, p=0.041), and with institutionalization was a lower Barthel index score at admission (OR=0.96, 95% CI=0.94-0.98, p=0.001). CONCLUSIONS: Our results shows that the factors associated with mortality one year after hip fracture surgery were: moderate dependence, malnutrition, in-hospital complications and advanced age. Having previous functional dependence is directly related to greater functional loss and institutionalization.

A neglected symptom? Parietal gait lateropulsion as primary manifestation of acute is-chemic stroke. / ¿Un síntoma negado? Lateropulsión parietal de la marcha como manifestación inicial de ictus isquémico agudo.

INTRODUCTION: Gait disorders are commonly overlooked as a presenting manifestation of stroke and underrepresented in case series. We describe four cases of sudden-onset gait lateropulsion as primary manifestation of parietal lobe stroke. CASE REPORT: Four patients presented after sudden-onset gait lateropulsion. On neurological examination, all patients had at least one cortical sensory deficit and wide-based gait with lateropulsion towards the side of the cortical deficit. Neuroimaging revealed a subacute parietal lobe stroke contralateral to the side of gait lateropulsion. In two patients we found bilateral lateropulsion with predominance towards the side of cortical deficit and increase of unsteadiness with eye closure (an apparent Romberg sign), with neuroimaging revealing bilateral parietal strokes (subacute contralateral and chronic ipsilateral to gait lateropulsion). CONCLUSION: We report gait lateropulsion as a novel primary manifestation of acute stroke of the parietal lobe (parietal gait lateropulsion). Given its role as the destination of proprioceptive pathways, parietal strokes can result in gait lateropulsion, with bilateral lesions even mimicking sensory ataxia with bilateral lateropulsion and unsteadiness upon eye closure.

TITLE: ¿Un síntoma negado? Lateropulsión parietal de la marcha como manifestación inicial de ictus isquémico agudo.Introducción. Los trastornos de la marcha no suelen considerarse dentro de las manifestaciones de presentación del ictus y están subrepresentados en las series de casos. Presentamos cuatro casos de lateropulsión de la marcha de inicio súbito como manifestación primaria de ictus del lóbulo parietal. Caso clínico. Cuatro pacientes se presentaron tras el inicio súbito de lateropulsión de la marcha. En el examen neurológico, todos tenían al menos un déficit sensitivo cortical, marcha de base amplia con lateropulsión ipsilateral al déficit cortical. En la neuroimagen se corroboró un ictus subagudo parietal contralateral al lado de lateropulsión de la marcha. Dos pacientes tenían lateropulsión bilateral con predominio ipsilateral al déficit cortical e incremento de inestabilidad con los ojos cerrados (simulando signo de Romberg), en quienes la neuroimagen demostró un ictus parietal bilateral (subagudo contralateral, crónico ipsilateral al lado de lateropulsión de la marcha). Conclusión. Describimos la lateropulsión de la marcha como una nueva manifestación inicial de ictus agudo del lóbulo parietal (lateropulsión parietal de la marcha), contralateral al lado de desviación de la marcha. Dado el papel del parietal como destino de las vías de propiocepción, los ictus pueden originar alteraciones de la marcha, con lesiones bilaterales que semejan ataxia sensitiva con inestabilidad al eliminar la aferencia visual.

OBJECTIVE: To identify the factors associated with mortality in patients after one year of being operated for hip fracture in an Orthogeriatric Program. METHODS: We design an observational analytical study in subjects older than 65 years admitted to the Hospital Universitario San Ignacio for hip fracture who were treated in the Orthogeriatrics Program. Telephone follow-up was performed one year after admission. Data were analyzed using a univariate logistic regression model and a multivariate logistic regression model was applied to control the effect of the other variables. RESULTS: Mortality was 17.82%, functional impairment was 50.91%, and institutionalization was 13.9%. The factors associated with mortality were moderate dependence (OR=3.56, 95% CI=1.17-10.84, p=0.025), malnutrition (OR=3.42, 95% CI=1.06-11.04, p=0.039), in-hospital complications (OR=2.80, 95% CI=1.11-7.04, p=0.028), and older age (OR=1.09, 95% CI=1.03-1.15, p=0.002). The factor associated with functional impairment was a greater dependence at admission (OR=2.05, 95% CI=1.02-4.10, p=0.041), and with institutionalization was a lower Barthel index score at admission (OR=0.96, 95% CI=0.94-0.98, p=0.001). CONCLUSIONS: Our results shows that the factors associated with mortality one year after hip fracture surgery were: moderate dependence, malnutrition, in-hospital complications and advanced age. Having previous functional dependence is directly related to greater functional loss and institutionalization.

Congenital malformations of the urinary tract: progression to chronic renal disease. / Malformaciones congénitas del tracto urinario (CAKUT): evolución a enfermedad renal crónica.

INTRODUCTION: Congenital nephrourological abnormalities (CAKUT) are a particularly relevant group of diseases due to their high prevalence and the fact they are the main cause of chronic renal disease (CRD) in the pediatric population. Our objective was to determine the characteristics and prevalence of CAKUT in our setting, while identifying the factors associated with the occurrence of renal damage. MATERIALS AND METHODS: A retrospective, descriptive, analytical, cross-sectional study of patients seen in the Pediatric Nephrology Department of a third-level hospital from January 1 to December 31, 2018 was carried out. Epidemiological, clinical, and analytical variables were assessed, and potential risk factors associated with CRD were searched for. RESULTS: The study involved 685 patients with 827 kidney units affected by CAKUT with a mean age of 9.98 ± 5.12 years. 62.2% were male, and the mean follow-up period after diagnosis was 9.95 ± 5.09 years. 58.8% were non-obstructive dilations, followed by renal dysplasia, obstructive dilations, and number and position abnormalities. The most frequent malformation was vesicoureteral reflux (VUR). The most commonly affected side was the left (47.5%). 55% of the diagnoses were prenatal. 172 patients underwent surgery. The initially chosen treatment for VUR was endourological. Overall re-intervention rate was 20%. Of the total number of patients, glomerular filtration rate was analyzed in 383, 95 (24.8%) of whom had CRD (86% in stage 2). Male sex, bilaterality, and proteinuria were risk factors associated with CRD. CONCLUSIONS: Knowledge of the epidemiological and clinical characteristics of children with CAKUT and the factors associated with CRD helps to individualize the clinical follow-up of these patients, thus customizing diagnostic tests and healthcare resources.

INTRODUCCION: Las anomalías nefrourológicas congénitas (CAKUT), constituyen un grupo de enfermedades de gran relevancia por su alta prevalencia y por ser la principal causa de enfermedad renal crónica (ERC) en la población pediátrica. Nuestro objetivo es conocer las características y la prevalencia de CAKUT en nuestro medio, identificando los factores asociados a la aparición de daño renal. MATERIAL Y METODOS: Estudio retrospectivo, descriptivo, analítico y transversal, que incluyó los pacientes atendidos en la consulta de Nefrología Pediátrica de un hospital de tercer nivel desde el 1 de enero al 31 de diciembre de 2018. Se analizaron variables epidemiológicas, clínicas y analíticas, y se buscaron posibles factores de riesgo asociados a ERC. RESULTADOS: Se incluyeron 685 pacientes con 827 unidades renales con CAKUT con una edad media de 9,98 ± 5,12 años. El 62,2% fueron varones y el seguimiento medio desde el diagnóstico fue de 9,95 ± 5,09 años. El 58,8% fueron dilataciones no obstructivas, seguido por displasia renal, dilataciones obstructivas y anomalías de número y posición. La malformación más frecuente fue el reflujo vesicoureteral (RVU). El lado más afectado fue el izquierdo (47,5%). El 55% de los diagnósticos fueron prenatales. Fueron intervenidos 172 pacientes. El tratamiento inicial de elección en el RVU fue endourológico. La tasa de reintervención global alcanzó el 20%. Del total de pacientes, se pudo analizar el filtrado glomerular en 383 pacientes, de los cuales 95 (24,8%) tenían ERC (86% en estadio 2). El sexo masculino, la bilateralidad y la proteinuria fueron factores de riesgo asociados a la ERC. CONCLUSIONES: El conocimiento de las características epidemiológicas y clínicas de los niños con CAKUT y de los factores asociados a la ERC ayuda a individualizar el seguimiento clínico de estos pacientes adecuando las pruebas diagnósticas y los recursos sanitarios.

Mutational spectrum of the iduronate-2-sulfatase gene in Mexican patients with Hunter syndrome.

OBJECTIVE: Hunter syndrome, or mucopolysaccharidosis type II (MPS II), is caused by deficiency of the lysosomal enzyme iduronate-2-sulfatase (IDS), which is responsible for degrading heparan and dermatan sulfate. The IDS gene is located on chromosome Xq28; pathological variants in this gene mostly consist of missense mutations and small and larger deletions, which produce different phenotypes. However, there is only one record in our population concerning the molecular mechanism of this disease; a genotype-phenotype description is not available. PATIENTS AND METHODS: There were included 24 unrelated male patients; clinical features were recorded at a database, fluorometric IDS enzyme activity testing was done for each individual, followed by Sanger sequencing to identify mutations. RESULTS: The mutational spectrum was found in 16 out of 24 Mexican patients with MPS II, and its range of phenotypes was described. The most frequent variants were of the missense type. The most affected exons were exon 3 (c.275T>G, c.284_287del, c.325T>C), exon 8 (c.1035G>C, c.550G>A), exon 9 (c.1403G>C, c.1229_1229del), and exon 7 (c.979A>C; this variant has not been previously reported). Exon 5 (c.438C>T, a non-pathogenic variant) was the least frequent. It was also found that the most severely affected patients were those with large deletions (2 out of 24) [rsaIDS: IDSP1 (P164)x0, FMR1, AFF2 (P164)x2] involving genes and pseudogenes. We found 2 patients with a synonymous mutation in exon 4. CONCLUSIONS: Our results confirmed reports in the literature, since the most frequent variants were reported in exons 3 and 8. However, this result varies from one previous report in our population, which mentions large deletions and rearrangements as the most frequent alterations, since complex rearrangements were not found. According to what has been previously found, the most severely affected patients are those in which a whole gene has been deleted.

Addressing child undernutrition in Tanzania with the ASTUTE program.

BACKGROUND: Optimal infant and young child feeding practices (IYCFP) reduce childhood stunting and are associated with additional health benefits. In Tanzania, IYCFP are far from optimal where 32% of children under the age of 5 years are stunted. The purpose of this study was to examine whether behavior change communication focused on reducing child undernutrition was associated with improved IYCFP in Tanzania. METHODS: A cross-sectional survey was administered to approximately 10,000 households with children under the age of 2 at baseline and endline. Bivariate analyses and logistic regression was used to examine the relationship between exposure to behavior change communication and timely initiation of breastfeeding, exclusive breastfeeding, continued breastfeeding at one year, timely complementary feeding (CF), minimum meal frequency (MMF), minimum dietary diversity (MDD), and minimum acceptable diet (MAD). RESULTS: Mothers who heard a radio spot about IYCFP were more likely than mothers who had not heard a radio spot about IYCFP to begin complementary foods at six months. Their children were also more likely to achieve MMF, MDD, and MAD with odds ratios of 2.227 (p = 0.0061), 1.222 (p = 0.0454), 1.618 (p = < .0001), and 1.511 (p = 0.0002), respectively. Mothers who saw a TV spot about IYCFP were more likely to have greater odds of knowing when to begin complementary feeding, feeding their child a minimally diverse diet (4 food groups or more), and serving a minimum acceptable diet with odds ratios of 1.335 (p = 0.0081), 1.360 (p = 0.0003), and 1.268 (p = 0.0156), respectively. CONCLUSION: Exposure to behavior change communication in Tanzania was generally associated with some increased knowledge of optimal IYCFP as well as practicing IYCF behaviors. Behavior change communication planners and implementers may want to consider conducting similar campaigns as an important component of behavior change to reduce undernutrition and poor health outcomes in developing settings.
