Abstract
OBJECTIVE This article aims to estimate the differences in environmental impact (greenhouse gas [GHG] emissions, land use, energy used, acidification and potential eutrophication) after one year of promoting a Mediterranean diet (MD). METHODS Baseline and 1-year follow-up data from 5800 participants in the PREDIMED-Plus study were used. Each participant's food intake was estimated using validated semi-quantitative food frequency questionnaires, and the adherence to MD using the Dietary Score. The influence of diet on environmental impact was assessed through the EAT-Lancet Commission tables. The influence of diet on environmental impact was assessed through the EAT-Lancet Commission tables. The association between MD adherence and its environmental impact was calculated using adjusted multivariate linear regression models. RESULTS After one year of intervention, the kcal/day consumed was significantly reduced (-125,1 kcal/day), adherence to a MD pattern was improved (+0,9) and the environmental impact due to the diet was significantly reduced (GHG: -361 g/CO2-eq; Acidification:-11,5 g SO2-eq; Eutrophication:-4,7 g PO4-eq; Energy use:-842,7 kJ; and Land use:-2,2 m2). Higher adherence to MD (high vs. low) was significantly associated with lower environmental impact both at baseline and one year follow-up. Meat products had the greatest environmental impact in all the factors analysed, both at baseline and at one-year follow-up, in spite of the reduction observed in their consumption. CONCLUSIONS A program promoting a MD, after one year of intervention, significantly reduced the environmental impact in all the factors analysed. Meat products had the greatest environmental impact in all the dimensions analysed.

Abstract
Mexico is an important producer/exporter of cattle and cattle products. In the last decade, an increase in antibiotic resistance in E. coli pathotype strains from livestock environments has been reported. This study aimed to determine the prevalence and antibiotic resistance profiles of E. coli pathotype strains from the feces of beef or dairy cattle reared in the states of Aguascalientes (AG, central) and Nuevo Leon (NL, northeastern) in Mexico. One hundred and ten fecal samples were collected (beef cattle-AG = 30; dairy cattle-AG = 20; beef cattle-NL = 30; dairy cattle-NL = 30). From these, E. coli was isolated using selective/differential media and confirmed on chromogenic media. Multiplex PCR was used to identify diarrheagenic E. coli, and the Kirby-Bauer technique was used to determine the antimicrobial susceptibilities. All the animals harbored E. coli, and pathotypes were found in 34 animals from both, beef and dairy cattle, mainly from Aguascalientes. Of the positive samples, 31 harbored a single E. coli pathotype, whereas three samples harbored two different pathotypes; EHEC was the most prevalent, followed by EPEC, ETEC, and EIEC or the combination of two of them in some samples. Most pathotype strains (19/37) were isolated from beef cattle. Neither the animals' productive purpose (beef or dairy cattle) (r = 0.155) nor the geographic regions (Aguascalientes or Nuevo Leon) (r = -0.066) had a strong positive correlation with the number of E. coli pathotype strains. However, animals reared in Aguascalientes had up to 8.5-fold higher risk of harboring E. coli pathotype strains than those reared in Nuevo Leon. All pathotype strains were resistant to erythromycin, tetracycline, and trimethoprim/sulfamethoxazole, and all dairy cattle pathotype strains were further resistant to five β-lactams (χ2, P = 0.017). The existence of these pathotypes and multidrug-resistant pathogens in the food chain is a risk to public health.

Abstract
Foodborne disease outbreaks linked to consumption of vegetables have been often attributed to human enteric viruses, such as Norovirus (NoV), Hepatitis A virus (HAV), and Rotavirus (RoV). Information about the occurrence of these viruses is scarce in many fresh-producing countries. Viral contamination detection of indicators, such as somatic coliphages, could indirectly reflect the presence of viral pathogens, being a valuable tool for better viral risk assessment in food industry. This study aimed to establish the occurrence and correlation of foodborne viruses and somatic coliphages in leafy greens in northern Mexico. A total of 320 vegetable samples were collected, resulting in 80 composite rinses, 40 of lettuce and 40 of parsley. Somatic coliphages were determined using the EPA 1602 method, while foodborne viruses (HAV, RoV, NoV GI, and GII) were determined by qPCR. The occurrence of RoV was 22.5% (9/40, mean 2.11 log gc/g) in lettuce and 20% (8/40, mean 1.91 log gc/g) in parsley. NoV and HAV were not detected in any samples. Somatic coliphages were present in all lettuce and parsley samples, with mean levels of 1.85 log PFU/100 ml and 2.28 log PFU/100 ml, respectively. Spearman analysis established the correlation of somatic coliphages and genomic copies of RoV, resulting in an r2 value of - 0.026 in lettuce and 0.349 in parsley. Although NoV or HAV were undetected in the samples, the presence of RoV is a matter of concern as leafy greens are usually eaten raw, which poses a potential risk of infection.

Abstract
Escherichia coli O104:H4, a hybrid serotype carrying virulence factors from enteroaggregative (EAEC) and Shiga toxin-producing (STEC) pathotypes, is the reported cause of a multicountry outbreak in 2011. Evaluation of potential routes of human contamination revealed that this strain is a foodborne pathogen. In contrast to STEC strains, whose main reservoir is cattle, serotype O104:H4 has not been commonly isolated from animals or related environments, suggesting an inability to naturally colonize the gut in hosts other than humans. However, contrary to this view, this strain has been shown to colonize the intestines of experimental animals in infectious studies. In this minireview, we provide a systematic summary of reports highlighting potential evolutionary changes that could facilitate the colonization of new reservoirs by these bacteria.

Abstract
The AcrAB-TolC efflux pump (EP) confers multidrug resistance to Salmonella enterica, a major etiological agent of foodborne infections. Phytochemicals that inhibit the functions of AcrAB-TolC EP present ideal candidates for reversal of antibiotic resistance. Progressive technological advancements, have facilitated the development of computational methods that offer a rapid low-cost approach to screen and identify phytochemicals with inhibitory potential against EP. In this study, 71 phytochemicals derived from plants used for medicinal purposes in Mexico were screened for their potential as inhibitors of Salmonella AcrB protein using in silico approaches including molecular docking and molecular dynamics (MD) simulation. Consequently, naringenin, 5-methoxypsoralen, and licarin A were identified as candidate inhibitors of AcrB protein. The three phytochemicals bound distal/deep pocket (DP) and hydrophobic trap (HPT) residues of AcrB protein critical for interactions with inhibitors, with estimated binding free energies of -95.5 kJ/mol, -97.4 kJ/mol, and -143.8 kJ/mol for naringenin, 5-methoxypsoralen, and licarin A, respectively. Data from the 50 ns MD simulation study revealed stability of the protein-ligand complex and alterations in the AcrB protein DP conformation upon binding of phytochemicals to the DP and HPT regions. Based on the estimated binding free energy and interactions with three out of five residues lining the hydrophobic trap, licarin A demonstrated the highest inhibitory potential, supporting its further application as a candidate for overcoming drug resistance in pathogens.

Abstract
OBJECTIVE This study aimed to analyze the association between rs3480 and rs16835198 of FNDC5/Irisin and their haplotypes with variations in bone mineral density (BMD) and osteopenia/osteoporosis in postmenopausal Mayan-Mestizo women. METHODS We studied 547 postmenopausal women of Maya-Mestizo origin. BMD was measured in the lumbar spine and total hip by dual-energy X-ray absorptiometry. DNA was obtained from blood leukocytes. rs3480 and rs16835198 of FNDC5/Irisin were studied using real-time PCR allelic discrimination. Differences between the means of BMD according to genotype were analyzed with covariance. Allele frequency differences were assessed by χ2 and logistic regression was used to test for associations. Pairwise linkage disequilibrium between polymorphisms was calculated by direct correlation r2, and haplotype analysis was conducted. RESULTS Under a recessive model, we observed a significant association of rs3480 with the presence of osteopenia at the total hip and femoral neck (p = 0.008 and p = 0.003, respectively). For rs16835198, we found an association with osteopenia at the total hip and femoral neck in a dominant model (p = 0.043 and p = 0.009, respectively). CONCLUSIONS We found an association of rs3480 with risk to present osteopenia at the total hip and femoral neck, while rs16835198 was associated as a protector for presence of osteopenia only at the femoral neck.

Abstract
Abstract
Study question
Do patients with high serum progesterone levels before frozen embryo transfer (FET) under hormonal replacement therapy (HRT) present worse reproductive outcomes?
Summary answer
Elevated serum progesterone levels before FET in artificially prepared cycles with vaginal or vaginal plus subcutaneous progesterone do not impair reproductive outcomes.
What is known already
Low serum progesterone levels before FET do negatively affect reproductive outcomes in terms of live birth rate. However, there is not robust data regarding the impact of high serum progesterone levels in the luteal phase of patients who undergo HRT for FET.
Study design, size, duration
Retrospective cohort study of 3183 blastocyst FET cycles under HRT performed in a university-affiliated fertility centre between March 2009 and December 2020. All the cycles presented adequate serum progesterone levels before FET (≥10.6 ng/ml). A total of 1360 cycles corresponded to frozen homologous embryo transfer (ET) (hom-FET), 1024 were euploid ET (eu-FET) after preimplantational genetic testing for aneuploidies (PGT-A), and 799 cycles were frozen heterologous ET (het-FET). The primary objective was live birth rate (LBR).
Participants/materials, setting, methods
Standard HRT was used. Luteal phase was covered with vaginal progesterone 200 mg/8h, or vaginal plus a daily subcutaneous injection of progesterone (25 mg). Serum progesterone levels were measured the day before FET. Elevated progesterone levels were considered in the 90th and 95th centiles. A generalized additive model (GAM) was performed to study the functional relationships between progesterone and LBR. A multivariable logistic regression was used to evaluate the effect of high progesterone over LBR.
Main results and the role of chance
Mean serum progesterone level before FET was 16.77±8.43 ng/ml. Progesterone levels were significantly higher in the group under vaginal plus subcutaneous progesterone (21.87±14.17 vs. 15.56±5.72, p < 0.001). No differences in clinical pregnancy, miscarriage and LBR were found according to the use of vaginal or vaginal plus subcutaneous progesterone for each of the groups (hom-FET, eu-FET and het-FET). Live birth rates were comparable among patients in the highest centile of serum progesterone levels (≥p90, ≥22.33 ng/ml) and the rest of patients (p < 90) (43.9 vs 41.3%; p = 0.381). Patients with progesterone levels ≥p90 presented lower BMI compared to those in the lower centiles (<p90) (22.62±3.82 vs. 23.32±4.06; P = 0.009). After dividing patients in deciles according to serum progesterone levels before, no differences in LBR were observed among groups (P = 0.938). No association was observed with GAM model between progesterone levels and LBR. A multivariable logistic regression adjusted by oocyte age, type of treatment and number of embryos transferred was applied for centile 90 and centile 95 of progesterone, and showed that serum progesterone in their highest levels did not negatively impact LBR.
Limitations, reasons for caution
The main limitation of this study is its retrospective design. The results only apply for patients under HRT with vaginal micronized progesterone alone or plus subcutaneous progesterone. Progesterone determination was measured before blastocyst FET. Extrapolation to other HRT protocols or timings of progesterone measurement needs to be validated.
Wider implications of the findings
The results of this study suggest that once a threshold of serum progesterone before FET is achieved, progesterone levels are not predictive of the clinical outcome. Actually, LBR are not negatively affected when progesterone levels are found in their highest centiles after luteal phase rescue with vaginal plus subcutaneous progesterone.

Abstract
Abstract
Study question
Is quality of life (QoL) and sexual function of poor ovarian responders affected by patients’ age and ovarian reserve?
Summary answer
QoL and sexual function in POR are only affected by infertility duration and number of previous IVF attempts; not by patients’ age and ovarian reserve.
What is known already
Diagnosis of infertility is a common cause of sexual health disorders. Couples undergoing Assisted Reproductive Technology (ART) can face emotional stress and feelings of inadequacy or guilt that may interfere in their quality life and sexual function, Poor ovarian responders may represent a group of patients with compromised sexual function and quality of life, owing to either their advanced age or the decline in the serum androgen levels observed in this population. Nonetheless, up to date evidence is scarce concerning clinical factors that may affect quality of life and sexual function of women with poor ovarian response.
Study design, size, duration
In a prospective study conducted between 2015 and 2021 we collected questionnaires from poor ovarian responders fulfilling the Bologna criteria concerning their quality of life and sexual function.
Participants/materials, setting, methods
Overall 70 women undergoing IVF treatment who fulfilled Bologna’s criteria for poor ovarian responders were interviewed at their first visit. Sexual distress was evaluated using the Female Sexual Distress Scale-Revised (FSDSR) and Quality of life was measured by a fertility questionnaire (FertiQOL). Bivariate statistical analysis was conducted in order to evaluate clinical factors (patients’ age, duration of infertility, previous IVF attempts and ovarian reserve) that could potentially negatively affect sexual distress and quality of life.
Main results and the role of chance
Patients’ mean age was 38.6 years old (with 20.6% of the patients being under 35, 33.8% between 35-39 and 45.6% were above 40 years). Infertility duration was less than a year for 22.1% of patients and over one year for 77.9% of patients. Most of patients (80.9%) had at least one previous IVF/ICSI treatment.
Quality of life and sexual function, as defined by FertiQol and FSDS-R scores, were comparable among different age groups, and older patients had similar QoL and sexual function with younger patients. Similarly, ovarian reserve did not affect any of the primary outcomes and no association has been found with AFC and FertiQol and FSDS-R scores.
The only variables affecting FertiQol and FSDS-R scores were the duration of infertility and the number of previous IVF attempts. Quality of life was significantly lower (75.4 vs 85.9, p < 0.001) among poor responders with previous IVF attempts (> or = 1), whereas sexual distress was higher (10.6 vs 2.54, p < 0.001) in women with previous IVF/ICSI treatment (>0 or = 1) and women with longer duration of infertility (>1 year vs ≤ 1 year) (10.2 vs 4.9, p = 0.049).
Limitations, reasons for caution
The results are only applicable to women who fulfil the Bologna criteria for poor ovarian response and cannot be generalized to all infertile women.
Wider implications of the findings
Low ovarian reserve and patients’ age have limited effect on quality of life and sexual distress of poor ovarian responders. Social and sexual concerns should be taken in consideration in Bologna poor responders, especially in those with longer duration of infertility and previous failed IVF attempts independent of their age.

Abstract
Abstract
Study question
Does the presence of FSHR SNPs influence late follicular phase progesterone and estradiol serum levels in predicted normoresponders treated with rFSH?
Summary answer
The presence of FSHR SNPs (rs6165, rs6166, rs1394205) had no statistically significant impact on late follicular phase serum progesterone and estradiol levels.
What is known already
Previous studies have shown that late follicular phase serum progesterone and estradiol levels are significantly correlated with the magnitude of ovarian response. Several authors have proposed that individual variability in the response to ovarian stimulation could be explained by variants in FSHR. So far, the literature is scarce on the influence of this genetic variability on late follicular phase steroidogenic response. Our aim is to determine whether genetic variants in the FSHR gene could modulate late follicular phase serum progesterone and estradiol levels.
Study design, size, duration
We performed a secondary analysis of a multicenter multinational prospective study including 366 patients from Vietnam, Belgium and Spain (166 from Europe and 200 from Asia), conducted from 11/2016-06/2019. All patients underwent ovarian stimulation followed by oocyte retrieval in an antagonist protocol with a fixed daily dose of 150IU rFSH. All patients had a serum progesterone and estradiol measurement on the day of trigger and were genotyped for 3 FSHR SNPs (rs6165, rs6166, rs1394205).
Participants/materials, setting, methods
Patients included were predicted normal responder women <38 years old undergoing their first or second ovarian stimulation cycle. The prevalence of late follicular phase elevated serum progesterone (EP), as well as mean serum progesterone and estradiol levels on the day of trigger were compared between the different FSHR SNPs genotypes. EP was defined as > 1.5 ng/ml.
Main results and the role of chance
The overall prevalence of EP was 15.8% (n = 58). No significant difference was found in the prevalence of EP in Caucasian and Asian patients (17.5% vs. 14.5%). Genetic model analysis revealed a similar prevalence of EP in co-dominant, dominant and recessive models for variants FSHR rs6166, rs6165 and rs1394205. Also, no statistically significant difference was found in the mean serum progesterone levels in the three genetic models. Likewise, FSHR SNPs genotypes had no statistically significant impact in the mean late follicular phase serum estradiol levels
Limitations, reasons for caution
This study is a post-hoc analysis of a multicenter multinational prospective cohort study. The results must be interpreted with caution considering the sample size of the EP group. The fact that a fixed daily dose of 150 IU rFSH was used in this population precludes the generalization of the results.
Wider implications of the findings
Based on our results, FSHR SNPs rs6165, rs6166, rs1394205 do not influence late follicular phase serum progesterone nor estradiol levels in predicted normal responders. These findings add to the controversy in the literature regarding the impact of individual genetic susceptibility in response to ovarian stimulation in this population.

Abstract
Abstract
Study question
Are fresh human sperm samples affected by different gravitational conditions than on Earth?
Summary answer
Motility and vitality of fresh human sperm samples are significantly decreased under microgravity conditions obtained by parabolic flight.
What is known already
Microgravity effects on the male reproductive system have mainly been studied in the animal model with diverse results and discouraging extrapolation in humans. While an increased motility was reported in bulls, mice models showed a decrease. Although preliminary data from the Micro-11 experiment presented by NASA reported human sperm alterations after microgravity exposure, our first study failed to show any significant effect of microgravity on “frozen” samples, suggesting that human sperm could be safely shipped outside the earth if important aspects related with cryopreservation were solved.
Study design, size, duration
Prospective study carried out in collaboration between the ART centre, a Technical University, and an Aviation Club specializing in parabolic flights.Two parabolic flights were conducted between 2020-2021, each consisting of 20 parabolic maneuvers, which means 160 seconds of microgravity exposure per sample. Fifteen sperm samples obtained from healthy men were included in the study in order to analyse the effects of microgravity and compare the results with those obtained in Earth gravity.
Participants/materials, setting, methods
Fresh sperm samples were checked pre-flight to evaluate vitality, concentration, motility and morphology. Samples were split into two to compare the effects of different gravity exposure: microgravity (flight) and Earth gravity (ground). After the flight, the same analysis were repeated, plus kinematics, DNA fragmentation by sperm chromatin dispersion, apoptosis by magnetic activated cell sorting, and oxidative stress by colorimetric test (Halosperm-Halotech). Computer Aided Semen Analysis (SCA-Scope) was used for cell counting.
Main results and the role of chance
On comparison of the mean values between fresh samples exposed to microgravity and those maintained on Earth gravity, statistical significant differences (p < 0,05) were found in the following parameters: vitality (69,7 ± 9,9 vs 72,4 ± 9,7 %), motile sperm concentration (23,7 ± 15,3 M/ml vs 31,5 ± 25,1 M/ml), grade “a” sperm concentration (8,7 ± 6,5 vs 11,7 ± 9,9 M/ml), percentage of spermatozoa with progressive motility (30 ± 12,9 vs 36 ± 14,3 %), curvilinear motility-VCL (45,7 ± 12,8 vs 47,7 ± 13,3 μm/s). Under the study conditions, non-statistically significant differences were observed in the other kinematic parameters: Lineal Velocity (VSL), Average Path Velocity (VAP), Straightness (STR), Amplitude of Lateral Head displacement (ALH), Linearity (LIN), Wobble (WOB), Beat-Cross Frequency (BCF), total sperm concentration (81,7 ± 112,1 vs 79,7 ± 89,8 M/ml), morphology (11,3 ± 6,3 vs 10,6 ± 5,3%), DNA fragmentation (14,6 ± 9,6 vs 15,7 ± 9,4), apoptosis (2,8 ± 2,8 vs 3,8 ± 4,4) and oxidative stress, since all samples maintained the same stress level in both splits.
Limitations, reasons for caution
Parabolic flight is an accepted ground-based method for obtaining microgravity conditions, but provides a short period of elapsed exposure to microgravity. Therefore, the results obtained need to be confirmed by using other platforms that provide a much longer time of exposure. More cases must be analysed to confirm the results.
Wider implications of the findings
Short exposure to microgravity significantly decreases sperm motility and vitality. Such an effect is likely to be stronger with longer exposure. These findings should be taken into account since this may eventually affect sperm fertilizing capacity and therefore natural conception or ART with fresh/frozen sperm, outside of the Earth.

Abstract
Abstract
Study question
Does the presence of FSHR variants influence the clinical pregnancy rate (CPR), live birth rate (LBR) and cumulative live birth rate (CLBR) in predicted normoresponders?
Summary answer
The presence of at least one G allele in FSHR variant rs6165 is associated with higher CPR and LBR when compared to genotype AA.
What is known already
FSHR protein expression has been found in the placenta, umbilical cord, amnion and decidua, suggesting a role in the promotion of a healthy pregnancy. Previous reports have analysed the impact of FSHR SNP rs6166 in pregnancy outcomes with conflicting results, mainly due to the heterogeneity in the inclusion criteria and limited sample size. Moreover, the literature is scarce regarding the association between FSHR SNPs rs6165 and rs1394205 and reproductive outcomes. Our aim is to determine whether FSHR SNPs rs6166, rs6166 and rs1394205 influence the reproductive prognosis following IVF.
Study design, size, duration
We performed a secondary analysis of a multicenter multinational prospective study, including 368 patients from Vietnam, Belgium and Spain (168 from Europe and 200 from Asia) from 11/2016-06/2019. All patients underwent ovarian stimulation with fixed-dose 150IU rFSH in an antagonist protocol.
Participants/materials, setting, methods
Patients aged <38 years, undergoing their first or second IVF cycle with a predicted normal response (antral follicle count >9 and/or antimullerian hormone >1.1ng/ml) were included. CPR, LBR and miscarriage rate (MR) in the first embryo transfer, as well as CLBR, were compared between the different genotypes of FSHR SNPs rs6166, rs6165 and rs1394205.
Main results and the role of chance
A total of 351 patients performed at least one embryo transfer (ET). Enrolled patients had a mean age of 30.5 ± 3.63 years. Mean CPR and LBR in the first ET were 56.1% and 48.4%, respectively. Univariate genetic model analysis revealed a significantly higher CPR in the dominant model for variant rs6165 (46.3% (38/82) for genotype AA vs 59.1% (159/269) for genotypes AG/GG, p = 0.04). No statistically significant difference was found regarding the CPR for variants rs6166 nor rs1394205. Also, no statistically significant difference was found in univariate analysis regarding LBR nor MR for the different FSHR variants. However, multivariable logistic regression analysis adjusted for patient age, BMI, ethnicity, type of embryo transfer, embryo stage and number of top quality embryos transferred revealed a statistically significant higher CPR and LBR for FSHR variant rs6165 genotype GG (adjOR 2.50, 95% CI 1.30-4.81, and adjOR 1.96, 95%CI 1.02-3.78, respectively). No statistically significant differences were found regarding CLBR for FSHR variants rs6166, rs6165 nor rs1394205.
Limitations, reasons for caution
The young age of the included patients precludes the generalization of the results to older patients. Also, the results should be confirmed in larger cohorts before being extrapolated to the general population.
Wider implications of the findings
Our results demonstrate a previously unreported association between variant FSHR SNPs rs6165 genotype GG and higher CPR and LBR and reinforce a potential role for the genetic background in the prediction of a favorable prognosis following IVF.

Abstract
BACKGROUND The Covid-19 pandemic has changed children's eating and physical activity behaviours. These changes have been positive for some households and negative for others, revealing health inequalities that have ramifications for childhood obesity. This study investigates the pandemic's impact on families of children aged 2-6 years with overweight or obesity. METHODS Drawing on interviews conducted as part of a randomised controlled trial (RCT) for childhood obesity, thematic analysis was used to examine how parents of pre-schoolers perceived changes in their eating, screentime and physical activity behaviours between the first and second waves of Covid-19. Parents (n = 70, representing 68 families) were interviewed twice during a period of 6 months in three countries with markedly different pandemic policies - Sweden, Romania, and Spain. The analysis is informed by Bronfenbrenner's ecological systems theory, which embeds home- and school-based influences within societal and policy contexts. RESULTS The findings show that, although all participants were recruited from an RCT for families of children with excess weight, they reported different responses to the pandemic's second wave, with some children engaging in healthier eating and physical activity, and others engaging in comfort eating and a more sedentary lifestyle. Differences in children's obesity-related behaviours were closely related to differences in parents' practices, which were, in turn, linked to their emotional and social wellbeing. Notably, across all sites, parents' feeding and physical activity facilitation practices, as well as their emotional and social wellbeing, were embedded in household resilience. In resilient households, where parents had secure housing and employment, they were better able to adapt to the challenges posed by the pandemic, whereas parents who experienced household insecurity found it more difficult to cope. CONCLUSIONS As the Covid-19 pandemic is turning into a long-term public health challenge, studies that address household resilience are crucial for developing effective prevention and treatment responses to childhood obesity.

Abstract
PURPOSE OF THE STUDY Currently no treatment has been proven to be efficacious for patients with early symptoms of COVID-19. Although most patients present mild or moderate symptoms, up to 5-10% may have a poor disease progression, so there is an urgent need for effective drugs, which can be administered even before the onset of severe symptoms, i.e. when the course of the disease is modifiable. Recently, promising results of several studies on oral ivermectin have been published, which has prompted us to conduct the present review of the scientific literature. METHODS A narrative review has been carried out, focusing on the following four main topics: a) short-term efficacy in the treatment of the disease, b) long-term efficacy in the treatment of patients with post-acute symptoms of COVID-19, c) efficacy in the prophylaxis of the disease, and c) safety of ivermectin. RESULTS The reviewed literature suggests that there seems to be sufficient evidence about the safety of oral ivermectin, as well as the efficacy of the drug in the early-treatment and the prophylaxis of COVID-19. CONCLUSIONS In the view of the available evidence, the Frontline COVID-19 Critical Care Alliance (FLCCC) recommends the use of oral ivermectin for both prophylaxis and early-treatment of COVID-19. Further well-designed studies should be conducted in order to explore the efficacy and safety of invermectin at low and high doses, following different dosing schedules, in both, the short and long-term treatment.

Abstract
Cantaloupe melons, which have been responsible of an increasing number of foodborne disease outbreaks, may become contaminated with microbial pathogens during production. However, little information is available on the microbial populations in the cantaloupe farm environment. The purpose of this work was to characterize the bacterial communities present on cantaloupe farms. Fruit, soil, and harvester hand rinsates were collected from two Mexican cantaloupe farms, each visited three times. Microbiome analysis was performed by sequencing 16sRNA and analyzed using qiime2 software. Correlations were determined between sample type and microbial populations. The α and β diversity analysis identified 2777 sequences across all samples. The soil samples had the highest number and diversity of unique species (from 130 to 1329 OTUs); cantaloupe (from 112 to 205 OTUs), and hands (from 67 to 151 OTUs) had similar diversity. Collectively, Proteobacteria was the most abundant phyla (from 42 to 95%), followed by Firmicutes (1-47%), Actinobacteria (< 1 to 23%), and Bacteroidetes (< 1 to 4.8%). The most abundant genera were Acinetobacter (20-58%), Pseudomonas (14.5%), Erwinia (13%), and Exiguobacterium (6.3%). Genera with potential to be pathogenic included Bacillus (4%), Salmonella (0.85%), Escherichia-Shigella (0.38%), Staphylococcus (0.32%), Listeria (0.29%), Clostridium (0.28%), and Cronobacter (0.27%), which were found at lower frequencies. This study provides information on the cantaloupe production microbiome, which can inform future research into critical food safety issues such as antimicrobial resistance, virulence, and genomic epidemiology.

Abstract
Ultraviolet radiation as a germicide is widely used in the health field and even in domestic hygiene. Here, we propose an improvement in low-cost portable units of filtration for indoor air, which is based on ultraviolet radiation. In the current technology, to carry out an air filtration with a suspension of aerosols in which there is a likely concentration of pathogens, whether viral, bacterial or molds, the air is forced to pass as close as possible to the ionizing radiation source (near field). Since the optical mass is very small, the desired effect can be achieved in a considerably short time, deactivating the infective potential of these biological agents. The proposal of this work is the regulation of the flow or speed control of passage through these filters by passive elements instead of by electronic control systems. For this, two devices have been designed, simulated, and built, obtaining similar net pathogen inactivation rates under different flow rates. The passive flow control device has demonstrated higher performance in terms of flow rate and lower cost of production since they do not require electronics and are produced with fewer diodes. This passive device has also shown a lower projection of maintenance cost, lower energy consumption rate (higher efficiency), and longer projection of useful life.

Abstract
Abstract
Study question
Is there any imbalance in the sex ratio (SR) and in the aneuploidy rate of male and female human blastocysts from a PGT-A programme?
Summary answer
Although SR in human blastocysts is significantly male-biased, more aneuploidies are observed among male blastocysts, resulting in comparable euploid male and female embryos available.
What is known already
More boys than girls are born worldwide, meaning that the SR at birth is biased towards males. Differences in the SR of children born after ART have been also reported. Factors such as the insemination technique or the day of embryo transfer have been shown to be related to the SR at birth, but whether the SR is shifted during the preimplantation and/or postimplantation development remains unknown. Study design, size, duration: Embryos from patients undergoing 921 PGT-A cycles from September 2017 to February 2020 were included in the study. Data from the chromosomal constitution of 2637 biopsied blastocysts was retrospectively analysed.
Participants/materials, setting, methods
Embryos were cultured in time-lapse incubators with low oxygen tension (5%) (Embryoscope®; Geri®) using single-step medium (Global®, LifeGlobal®; GTL™, Vitrolife). Blastocyst biopsy was performed between D5-D7 followed by immediate vitrification (Cryotop®, Kitazato). Trophectoderm samples were analysed by NGS. Embryos were categorized as euploid, aneuploid or mosaic. Embryos were called as mosaic when the deviation from the normal copy number was ≥30% and <70%.
Main results and the role of chance
Overall biopsies from 2637 blastocysts were analysed, 1320 on day 5 (50.1%), 1169 on day 6 (44.3%) and 148 on day 7 (5.6%). Sex distribution among the embryos analysed was skewed in favor of male sex with 1401 diagnosed as male (53.1%) and 1236 were female (46.9%), [OR (95%CI):1.13(1.05–1.22)]. As a consequence of this biased SR, more male embryos reached the blastocyst stage and were biopsied both on day 5/6 (708/1320, 53.6% on day 5 and 619/1169, 53% on day 6). Embryos biopsied on day 7 were balanced between sexes with 50% being male and 50% being female. Following biopsy and PGT-A, 1086 (41.2%) of the embryos were classified as euploid, 1349 (51.16%) as aneuploid, and 202 (7.7%) as mosaic embryos. More chromosomal anomalies were observed among male blastocysts when compared to the female ones, 738 (52.7%) vs 611 (49.4%). Similarly, mosaicism was more frequents in male as compared with female blastocysts, 123 (8.8%) vs 79 (6.4%). (P = 0.000). As more aneuploidies are observed among male blastocysts, the final number of available euploid blastocysts for embryo transfer was comparable between sexes (540 male/546 female), [OR (95%CI): 0.99 (0.87–1.11)].
Limitations, reasons for caution
This is a retrospective study. Only embryos at the blastocyst stage have been analyzed. Potential confounding factors such as sperm quality or the female age have not been analyzed. No data regarding the SR at birth have been analyzed in these study.
Wider implications of the findings: In our study, more male embryos develop to the blastocyst when compared to female ones. It can be hypothesized that female embryos can be more affected by an early arrest at cleavage stages. SR at birth would be expected to be similar as more aneuploidy is observed in male embryos.

Abstract
Abstract
Study question
Does progesterone-supplementation (PS) from the day of β-hCG assessment improve pregnancy rates in embryo transfer-under hormonal replacement therapy (ET-HRT) in patient with Progesterone (P)<10.6 ng/mL?
Summary answer
Reduced P on the β-hCG day is associated with lower pregnancy-rates and higher miscarriage-rate. PS from the same day showed significant increase of reproductive outcomes.
What is known already
Up until now, in ART, very little has been done to understand whether the P intake should be personalized during the luteal phase. Most recent studies on the topic showed that low P levels on the day of ET-HRT or on the day before are associated with decreased pregnancy rates; however, when low P values are supplemented from the day before embryo-transfer (ET), similar results to cases with adequate P are reported. Nevertheless, little is known about the association between low P level, on the day of β-hCG (P- β-hCG) and PS from this day in ET-HRT, and pregnancy outcomes.
Study design, size, duration
This is a single centre, cohort, retrospective study conducted at a university-affiliated fertility centre between January 2018 and June 2020 where PS took place from the day of positive β-hCG determination when P < 10.6 ng/mL. In total 789 ET-HRT cycles were analysed of which 239 were performed in both fresh and frozen heterologous ET-HRT (het-ET), 336 in homologous ET-HRT (hom-FET) and 214 in euploid ET-HRT (eu-FET) after preimplantation genetic testing for aneuploidies IVF cycles (PGT-A).
Participants/materials, setting, methods
Women undergoing ET-HRT with normal P (>10.6ng/mL) on the day before ET were screened for P on the day of β-hCG. All women received vaginal P 200 mg/8 hours for the second part of HRT. PS was performed by adding P to the HRT when P- β-hCG was considered low (<10.6 ng/mL). Primary outcome: ongoing-pregnancy-rate (OPR); secondary outcome: miscarriage-rate (MR). Both were evaluated by considering PS on the day of β-hCG as a categorical variable.
Main results and the role of chance
Patients characteristics were comparable between groups (het-ET, hom-FET and eu-FET) although significantly lower body mass index was found when P- β-hCG>10.6 ng/mL compared to the subgroup with P- β-hCG<10.6 ng/mL and no PS (p = 0.012). Overall clinical pregnancy rate was 52.1% with no-significant differences between groups (48.5% in het-ET, 52.9% in hom-FET and 54.7% in eu-FET). P- β-hCG was considered as adequate in 75.7% (311/411) ET-HRT with positive β-hCG and low in 24.3% (100/411), with no differences between groups. In case of positive β-hCG and P- β-hCG >10.6 ng/mL, OPR was 83.6% and MR was 16.4%, with no-significant differences between groups. Among the 100 low P- β-hCG, 80 ET-HRT received PS. In this subgroup OPR was 96.2% and MR was 3.8%, with no-significant differences between groups. In 20 out of 100 ET with P- β-hCG <10.6 ng/mL, no PS was added for different reasons. This group showed the lowest OPR (30%) and the highest MR (70%), again with no between-group differences according to het-ET, hom-FET or eu-FET. Miscarriage rate was significantly higher (p < 0.001) when P- β-hCG was <10.6 ng/mL and no PS was added to HRT compared to P- β-hCG <10.6 ng/mL but with PS, and also compared to the P- β-hCG >10.6 ng/mL group.
Limitations, reasons for caution
The main limitation of the study is due to its retrospective nature and the small sample of patients with P- β-hCG<10.6 ng/mL that was not supplemented. Furthermore, the cut-off of P- β-hCG was arbitrarily decided upon previous studies, and lastly different routes of administration were considered for the PS.
Wider implications of the findings: The results of this study showed that individualization of Progesterone supplementation in ET-HRT may be a crucial turn point in order to increase the pregnancy rates and decrease the miscarriage rates. An adequate PS should be considered in case of low P- β-hCG levels for both het-ET, hom-FET and eu-FET.

Abstract
Adherence of bacteria to the human intestinal mucosa can facilitate their internalization and the development of pathological processes. Escherichia coli O104:H4 is considered a hybrid strain (enteroaggregative hemorrhagic E. coli [EAHEC]), sharing virulence factors found in enterohemorrhagic (EHEC), and enteroaggregative (EAEC) E. coli pathotypes. The objective of this study was to analyze the effects of natural and synthetic antimicrobials (carvacrol, oregano extract, brazilin, palo de Brasil extract, and rifaximin) on the adherence of EHEC O157:H7, EAEC 042, and EAHEC O104:H4 to HEp-2 cells and to assess the expression of various genes involved in this process. Two concentrations of each antimicrobial that did not affect (p≤0.05) bacterial viability or damage the bacterial membrane integrity were used. Assays were conducted to determine whether the antimicrobials alter adhesion by affecting bacteria and/or alter adhesion by affecting the HEp-2 cells, whether the antimicrobials could detach bacteria previously adhered to HEp-2 cells, and whether the antimicrobials could modify the adherence ability exhibited by the bacteria for several cycles of adhesion assays. Giemsa stain and qPCR were used to assess the adhesion pattern and gene expression, respectively. The results showed that the antimicrobials affected the adherence abilities of the bacteria, with carvacrol, oregano extract, and rifaximin reducing up to 65% (p≤0.05) of E. coli adhered to HEp-2 cells. Carvacrol (10 mg/ml) was the most active compound against EHAEC O104:H4, even altering its aggregative adhesion pattern. There were changes in the expression of adhesion-related genes (aggR, pic, aap, aggA, and eae) in the bacteria and oxidative stress-related genes (SOD1, SOD2, CAT, and GPx) in the HEp-2 cells. In general, we demonstrated that carvacrol, oregano extract, and rifaximin at sub-minimal bactericidal concentrations interfere with target sites in E. coli, reducing the adhesion efficiency.

Abstract
Cantaloupes contaminated with pathogens have led to many high-profile outbreaks and illnesses. Since bacterial virulence genes (VGs) can act in tandem with antibiotic-resistance and mobile genetic elements, there is a need to evaluate these gene reservoirs in fresh produce, such as cantaloupes. The goal of this study was to assess the distribution of antibiotic-resistance, virulence, and mobile genetic elements genes (MGEGs) in cantaloupe farm environments. A total of 200 samples from cantaloupe melons (n = 99), farm workers' hands (n = 66), and production water (n = 35) were collected in México. Each sample was assayed for the presence of 14 antibiotic-resistance genes, 15 VGs, and 5 MGEGs by polymerase chain reaction. Our results indicated that tetracycline (tetA and tetB) (18% of cantaloupe, 45% of hand samples) and sulfonamide (sul1) (30% of cantaloupe, 71% of hand samples) resistance genes were frequently detected. The colistin resistance gene (mcr1) was detected in 10% of cantaloupe and 23% of farm workers' hands. Among VGs, Salmonella genes invA and spiA were the most abundant. There was a significantly higher likelihood of detecting antibiotic-resistance, virulence, and MGEGs on hands compared with water samples. These results demonstrate a diverse pool of antibiotic-resistance and VGs in cantaloupe production.

Abstract
OBJECTIVE The objective of this work is to present initial perioperative, immediate continence and oncological results in a series of 25 prostate cancer patients treated with Retzius-sparing robot-assisted radical prostatectomy. MATERIAL AND METHODS We retrospectively analyzed a series of 25 patients treated with Retzius-sparing robot-assisted radical prostatectomy for cT1-T2b prostate cancer between 2018-2019. The 5 stages of surgery are described. We make a descriptive statistic of our initial series and its outcomes in terms of immediate continence, defined as the use of 0 pad/diapers or 1 safety pad/diaper every 24 hours, one week after catheter removal. RESULTS Median follow-up, 6 months (3-18). Median PSA, 6.1 ng/ml (4-14.3). All surgeries were performed through a posterior intrafascial approach, and bilateral nerve-sparing was carried out in 84% of the cases. Affected surgical margins were present in 28%, being the apex the most frequent site of affectation. Surgical complications: 1 (4%) patient required transfusion of blood products in the immediate postoperative period. Mean hospital stay was 48 hours. Functional outcomes: 80% of the patients present immediate continence. 80% of continent patients do not require the use of any safety pads/diapers. Oncological outcomes: 84% are free of biochemical-progression in a median follow-up of 6 months. CONCLUSIONS Initial functional results in terms of immediate continence are very satisfactory in patients who have undergone Retzius-sparing robot-assisted radical prostatectomy without negative impact on prognosis.

Abstract
PURPOSE Microgravity has severe effects on cellular and molecular structures as well as on metabolic interactions. The aim of this study is to investigate the effects of microgravity (μg) exposure on human frozen sperm samples. METHODS Sibling samples from 15 normozoospermic healthy donors were frozen using glycerol as cryoprotectant and analyzed under microgravity and ground conditions. Microgravity was obtained by parabolic flights using a CAP10B plane. The plane executed 20 parabolic maneuvers with a mean of 8.5 s of microgravity for each parabola. RESULTS Frozen sperm samples preserved in cryostraws and stored in a secure and specific nitrogen vapor cryoshipper do not suffer significant alterations after μg exposure. Comparing the study group (μg) and the control group (1 g), similar results were obtained in the main parameters studied: sperm motility (M/ml) 13.72 ± 12.57 vs 13.03 ± 12.13 (- 0.69 95% CI [- 2.9; 1.52]), progressive a + b sperm motility (%) 21.83 ± 11.69 vs 22.54 ± 12.83 (0.03 95% CI [- 0.08; 0.15]), sperm vitality (%) 46.42 ± 10.81 vs 44.62 ± 9.34 (- 0.04 95% CI [- 0.13; 0.05]), morphologically normal spermatozoa (%) 7.03 ± 2.61 vs 8.09 ± 3.61 (0.12 95% CI [0.01; 0.24]), DNA sperm fragmentation by SCD (%) 13.33 ± 5.12 vs 13.88 ± 6.14 (0.03 95% CI [- 0.09; 0.16]), and apoptotic spermatozoa by MACS (%) 15.47 ± 15.04 vs 23.80 ± 23.63 (- 0.20 95% CI [- 0.66; 1.05]). CONCLUSION The lack of differences obtained between frozen samples exposed to μg and those maintained in ground conditions provides the possibility of considering the safe transport of human male gametes to space. Nevertheless, further research is needed to validate the results and to consider the possibility of creating a human sperm bank outside the Earth. TRIAL REGISTRATION NUMBER ClinicalTrials.gov: NCT03760783.

Abstract
Introduction Non-communicable diseases are increasing worldwide due mainly to rapidly changing lifestyles and socio-economic status affecting the well-being and the lives of young people along their whole life. Hence, there is a need to provide adequate and useful measures to support patients living with those diseases in order to foster youth emotional and physical health and improve their daily life.
Objectives The aim of this presentation is to demonstrate the use of eLearning content to empower families, communities and young patients in dealing with the daily routine of chronic diseases.
Methodology Based on a human centred design, 176 youngsters with asthma, obesity, and diabetes aged between 3-16 years old were assessed to gather information about perceived needs and preferences in relation to disease management. Ineffective communication, lack of knowledge/skills, poor adherence to treatment and low acceptance of the disease were the main aspects highlighted. Based on those results, participants were fully involved participating in the iterative development of eLearning package to face these needs, gathering specific information about its content, design and usability.
Results The project has generated eLearning modules, using Articulate technologies, providing practical information and learning content in three languages, in partnership with health research centres, hospitals and patient associations in Portugal, Spain and France. There are lots of packages: obesity, respiratory diseases and diabetes. In each of these, the content is provided using gamification strategies and role models. eLearning is one of the components of the follow up process, being complemented by a mobile application with an interactive support chat and fun games.
Conclusion ELearning tools, along with other online tools, contribute to generate a more positive perspective on the control of the disease and to support families and patients to get reliable information and connect with medical assistance.

Abstract
Most Escherichia coli strains are innocuous to human beings; however, some strains can cause diarrhea and are grouped into pathotypes. Since current trends promote the use of natural-origin compounds to control bacteria, in this study, the effects of the phenolic compounds (PCs) tannic acid (TA), gallic acid (GA), methyl gallate (MG), and epigallocatechin gallate (EG) on the growth, swarming motility, biofilm formation, and expression of selected virulence genes of three E. coli pathotypes (enteropathogenic Escherichia coli [EPEC], enterohemorrhagic Escherichia coli [EHEC], and enterotoxigenic Escherichia coli [ETEC]) were evaluated. Minimum bactericidal concentrations (MBCs) were determined by using microtiter plates, and the effects of sublethal PC concentrations on swarming motility were evaluated on Luria-Bertani agar. Biofilm formation was assessed in microtiter plates via crystal violet staining, and the expression levels of genes involved in biofilm formation (flhC, fliA, fliC, and csgA) and swarming motility (csgD and cyaA) were evaluated via quantitative PCR. All PC were bactericidal with minimal bactericidal concentrations ranging from 0.07 to 2.1 mg/mL. At concentrations lower than the MBC, PCs decreased swarming motility (14.8-100%). GA reduced biofilm formation in all of the tested strains; however, TA, MG, and EG induced biofilm formation in some strains at specific concentrations. TA induced the overexpression of csgA, csgD, and cyaA, whereas the other PCs did not have any effects or reduced their expression levels. The PCs tested in this study showed potential to control E. coli strains belonging to the EHEC, ETEC, and EPEC pathotypes by affecting their growth, swarming motility, and virulence gene expression; however, proper concentrations must be used to avoid the induction of undesirable virulence factor genes.

Abstract
In order to determine the microbial safety of produce, conventional fecal indicator bacteria (CFIB) such as Escherichia coli and Enterococcus are quantified as a standard practice. Bacteroidales are also fecal indicators mostly used for water samples; however, their use and persistence in foods has been rarely studied. In this study, persistence of both CFIB and genetic markers of host-specific Bacteroidales was determined in artificially contaminated materials and vegetables with different textured surfaces under different storage conditions. Sterile feces were contaminated with E. coli, E. faecalis, Bacteroidesthetaiotaomicron (human origin), and Bacteroidales from porcine and bovine origin. Feces were applied to filters of mixed cellulose esters and tomatoes (smooth surface) and flat cork coupons and melons (rough surface) and stored at 10 °C/95% relative humidity (RH) and 25 °C/65%RH for up to 25 days. Bacteroidales markers were analyzed by real-time polymerase chain reaction (qPCR), whereas CFIB were plated onto selective agars. CFIB detection on filters and cork surfaces declined over time. E. coli decreased 2.9 log CFU and 1.2 log CFU per filter and cork, respectively, at 10 °C/95%RH and 5.8 log CFU and 1.8 log CFU per filter and cork, respectively, at 25 °C/65%RH. E. faecalis decreased 1.9 log CFU on filters and 1.3 log CFU on cork at 10 °C/95%RH and 2.6 log CFU/filter and cork under both storage conditions. Although E. coli levels in tomatoes slightly increased during storage, the levels decreased by the end of the assays. However, CFIB levels in melons stored at 10 °C/95%RH increased after 20 days; when stored at 25 °C/65%RH, these levels increased after five days. Bacteroidales levels (universal and host-specific markers) in inanimated material and produce did not show significant differences (P ≤ 0.01) over time. Stability and persistence of Bacteroidales genetic markers make them superior to CFIB as markers and are alternatives for determining the risk of exposure to feces-contaminated produce.

Abstract
To characterize the influence of hypothyroidism on the endocrine activity of mesenteric and omental adipose tissue (MOAT) and the peripheral regulation of energy balance (EB) in rats, we analyzed food intake (FI); basal metabolic rate (BMR); locomotor activity; body weight (BW); serum hormone concentrations and the expression of their receptors in MOAT. We evaluated the morphology and differentiation of adipocytes. Hypothyroidism decreased FI, BMR and BW. The percentage of visceral white adipose tissue (WAT) depots and the morphology of adipocytes were similar to euthyroid rats. Serum leptin and adiponectin expression in MOAT were altered by hypothyroidism. The expression of Perilipin 1, HSL, UCP1 and PRDM16 was significantly lower in MOAT of hypothyroid animals. Hypothyroidism in rats leads to a compensated EB by inducing a white adipocyte dysfunction and a decrease in BW, BMR, FI and adipokine secretions without changing the percentage of WAT depots and the morphology of the MOAT.

Abstract
OBJECTIVE Interfascial blocks of the thoracic wall are being developed as an alternative to central blocks in breast surgery. However, there are few studies that have evaluated the anatomical extension of the local anaesthetic. The objective of this study was to analyse, using fluoroscopy, the spreading of two volumes (10 vs. 20ml) of radiological contrast in the serratus-intercostal plane block in an experimental pig model. MATERIAL AND METHODS Ten Large-White breed pigs were selected to have a bilateral ultrasound serratus-intercostal plane block performed, with the administering of 10ml and 20ml of iopamidol in the right and left hemithorax, respectively. The spreading of contrast was analysed by fluoroscopy. The Spearman test correlation was used to evaluate the relationship between the administered volume and radiological spreading. A value of P<.05 was considered significant. RESULTS Twenty anaesthetic blocks were performed, being able to analyse 18 of them. The administration of 10ml of contrast was associated with a mean spreading of 2.28±0.31 (95% CI; 2.01-2.54) intercostal spaces, while the administration of 20ml showed a spreading of 3±0.25 (95% CI; 2.81-3.18) intercostal spaces. There was a significant correlation between the injected volume and the spreading of the contrast (Spearman correlation coefficient of 0.81; P=.0001). CONCLUSION The results showed a spreading of volume subject to the serratus-intercostal plane block, although not maintaining a 1:1 ratio. Doubling the volume increased the blocked segments by 31%. These findings, if corroborated in the clinical practice, would allow a more precise adjustment in the anaesthetic volume administered.

Abstract
Chihuahua cheese is a traditional cheese produced in Northwest Mexico that is consumed shortly after production. Cheeses prepared during autumn, winter and summer were collected from five dairies, and analyzed to determine seasonal influence on proximate analysis, texture profile and the microbiological dynamic during a ripening period of 270 days. Coliforms, coagulase-positive staphylococci, molds, yeast, as well as presumptive mesophilic lactobacilli, thermophilic lactobacilli, lactococci, thermophilic cocci and enterococci, were enumerated by plate count on selective agar. Manufacturing dairy had an effect on Chihuahua cheese composition and texture profile. Seasonality influence on the microbial dynamic was observed, since the highest initial counts of coliforms (5.14 log CFU/g), coagulase-positive staphylococci (4.13 log CFU/g) and mesophilic lactobacilli (7.86 log CFU/g) were detected on summer samples. Also, ripening time affected the survival of coliforms and presumptive lactococci after 270 days (1.24 and 5.89 log CFU/g respectively) while from day 90th, coagulase-positive staphylococci were absent. Microbial changes and seasonal influence provide information on the microbiota that can influence the sensorial characteristics of Chihuahua cheese.

Abstract
Food-producing animals are the major reservoirs for many foodborne pathogens such as Campylobacter species, non-Typhi serotypes of Salmonella enterica, Shiga toxin-producing strains of Escherichia coli, and Listeria monocytogenes. The zoonotic potential of foodborne pathogens and their ability to produce toxins causing diseases or even death are sufficient to recognize the seriousness of the situation. This manuscript reviews the evidence that links animals as vehicles of the foodborne pathogens Salmonella, Campylobacter, Shiga toxigenic E. coli, and L. monocytogenes, their impact, and their current status. We conclude that these pathogenic bacteria will continue causing outbreaks and deaths throughout the world, because no effective interventions have eliminated them from animals and food.

Abstract
Most methods that investigate fecal contamination of vegetables do not address the origin of contamination. Because host-specific sequences are conserved in their genomes, bacteria of the order Bacteroidales are regarded as alternative indicators for tracking sources of contamination of produce. The objective of this study was to determine the efficacy of host-specific Bacteroidales markers to identify sources of fecal contamination and to determine whether detection of Bacteroidales markers correlated with traditional fecal indicator bacteria (FIB) in strawberries and tomatoes. Tomato and strawberry samples were artificially contaminated with human and animal feces, which contained 6 to 7 log CFU Bacteroidales per 100 mL and 3 to 6 log CFU/100 mL of the bacterial indicators Escherichia coli, total coliforms, and Enterococcus. FIB were enumerated by standard procedures. Universal and host-specific Bacteroidales markers were detected and quantified by quantitative PCR, and the detection range was 1.35 to 10.35 logarithmic gene copies, which corresponds to a limit of detection of two Bacteroidales cells. Few correlations between levels of Bacteroidales and levels of FIB were observed. For most of the contaminated tomato and strawberry samples, Bacteroidales levels were higher than FIB levels, and detection of FIB was highly variable. Detection of Bacteroidales markers was similar to total coliforms when ≥0.1 mg of feces was inoculated. These indicators were better than E. coli and Enterococcus for detection of fecal contamination in produce. The host-associated Bacteroidales markers were detected at an inoculum of 1 mg of feces per produce item (except those from bovine feces in strawberry). All of the host-associated Bacteroidales markers were detected at an inoculum of 10 mg of feces per produce item. Thus, Bacteroidales markers are promising tools to identify sources of fecal contamination; however, more research is required for their potential use to reduce the risks of contamination of produce.

Abstract
The interaction between humans and small carnivores is a phenomenon especially frequent in rural fringes, as is the case of communities surrounding natural areas. In Chile, two species of threatened carnivores, the Darwin’s Fox and the Guigna, have increased their contact with humans due to human-induced changes in their habitat. The objective of this study was to characterize the interactions of these species with humans by assessing human perceptions and attitudes toward them, and to assess livestock and poultry ownership and management practices in local communities to evaluate their possible roles in the phenomenon. We conducted semi-structured interviews in rural communities adjacent to natural protected areas of two different regions in southern Chile. We found that people have a more positive perception of Darwin’s Foxes than Guignas, but both species are considered damaging due to poultry attacks. Livestock and poultry management was generally deficient. Improvements in animal management and education programs could lead to a significant decrease in negative interactions.

Abstract
ResumenLa lesión de los nervios mediano y cubital puede ocasionar daños permanentes y tiene consecuencias devastadoras. Los accidentes con instrumentos cortantes en ambiente laboral o doméstico y las lesiones del plexo braquial, constituyen las causas más frecuentes. En los casos de lesión del nervio mediano, recuperar la sensibilidad de la “pinza” (borde cubital del pulgar y radial del índice), es esencial para la reeducación de la función motora e incluso, puede considerarse un requisito previo. Asimismo, la lesión del nervio cubital, conlleva a déficit de sensibilidad del borde medial de la mano y produce falta de soporte para la manipulación con la pinza. En ambos casos, la mano está expuesta a traumatismos, heridas, quemaduras, etc. En el momento de la lesión y siempre que sea posible, debe realizarse una reparación primaria del nervio. Las avulsiones, las lesiones proximales y los grandes defectos nerviosos, obligan a una reconstrucción secundaria cuando el paciente se ha recuperado de la lesión aguda. Este estudio objetiva una actualización de la literatura.

Abstract
OBJECTIVE To determine the frequency of nine sexually transmitted pathogens, coinfections and risk factors in patients attending obstetrics and gynecology clinics in Jalisco, Mexico. MATERIALS AND METHODS Samples from 662 patients attending obstetrics and gynecology clinics were analyzed. Treponema pallidum, HIV, and HCV were detected by serology. HPV was detected by Polimerase Chain Reaction (PCR), and its genotype was determined by Restriction Fragment Length Polymorphism (RFLP). Trichomonas vaginalis, HSV-1, HSV-2, Mycoplasma genitalium, Neisseria gonorrhoeae and T. pallidum were detected by multiplex PCR. RESULTS By serology, HIV frequency was 6.8%, T. pallidum was 2.26%, and HCV was 0.15%. By PCR, HPV frequency was 13.9%, (more frequent genotype was 16, 33.7%), followed by T. vaginalis (14.2%), HSV-1 (8.5%), M. genitalium (2,41%), N. gonorrhoeae (2.11%), HSV-2 (1.8%), and T. pallidum (1.05%). Patients infected with T. vaginalis were more likely to have multiple coinfections (p = 0.01). CONCLUSION The frequency of HPV, HVS-1, HSV-2, M. genitalium and T. vaginalis was lower than that reported. However, a high frequency of HIV, T. pallidum, and N. gonorrhoeae was detected.

Abstract
Food handlers are important sources of contamination in the agricultural environment. This study was conducted (i) to evaluate the activity of antimicrobial soaps against Escherichia coli and Enterococcus faecalis using a hand washing model with soiled hands and (ii) to determine the survival and persistence of these bacteria in rinsates. Sterilized agricultural soil from tomato and pepper farms was inoculated with E. coli or E. faecalis at 103 or 106 CFU/g. Decontaminated hands were placed in contact with contaminated soil for 2 min and were then washed with soaps with or without antimicrobial compounds (citric extracts, chloroxylenol, triclosan, or chlorhexidine gluconate). As the control, hands were washed with sterile distilled water. The levels of bacteria remaining on the hands and recovered from the rinsates were determined using a membrane filtration method and selective media. Antimicrobial soaps removed levels of E. coli similar to those removed by distilled water and nonantimicrobial soap on hands contaminated with E. coli at 103 CFU/g. However, when hands were contaminated with E. coli at 106 CFU/g, more E. coli was removed with the chlorhexidine gluconate soap. When hands were contaminated with E. faecalis at 103 CFU/g, bacteria were removed more effectively with soaps containing chloroxylenol or chlorhexidine gluconate. When hands were contaminated with E. faecalis at 106 CFU/g, all of the antimicrobial soaps were more effective for removing the bacteria than were distilled water and nonantimicrobial soap. E. coli grew in all of the hand washing rinsates except that containing triclosan, whereas E. faecalis from the 106 CFU/g treatments grew in rinsates containing chlorhexidine gluconate and in the distilled water rinsates. Washing with antimicrobial soap was more effective for reducing bacteria on soiled hands than was washing with water or nonantimicrobial soap. However, persistence or growth of bacteria in these rinsates poses health risks.

Abstract
BACKGROUND Chlamydia trachomatis is the causative agent of the most common bacterial sexually transmitted infection worldwide. The aim of this study was to investigate the frequency and genotypes of C. trachomatis in patients attending an obstetrics and gynecology clinic in Jalisco, Mexico and correlates them with sociodemographic, behavioral, and biological factors. METHODS C. trachomatis detection was performed in endocervical samples from 662 patients by direct fluorescence assay (DFA) and two PCR assays that amplified the phospholipase D endonuclease superfamily protein (PLDESP) and OmpA genes. Positive samples were genotyped using PCR-restriction fragment length polymorphism assays. Sociodemographic, behavioral, and biological data were collected. RESULTS The mean age of the study population was 31 (range, 14-78) years. C. trachomatis positivity was detected by DFA in 16.7% (n = 111), PLDESP gene amplification in 14.2% (n = 94), and OmpA gene amplification in 14.5% (n = 96) of the population. Eight C. trachomatis genotypes were detected: E (39.6%), F (29.2%), D (15.6%), K (6.3%), L2 (3.1%), G, J, and I (2.1% each). C. trachomatis infection was associated with age, marital status, pregnancy, and hormonal contraceptive use (all p = 0.01); intrauterine device use and previous premature birth (both p = 0.03); and infection during pregnancy, previous ectopic pregnancy, pelvic inflammatory disease (PID), and green vaginal discharge (all p = 0.04). C. trachomatis genotype K was more likely to be detected in women histories of ≥2 sexual partners, genotype F was more likely in pregnant women, genotype L2 was more likely in women with PID, genotype D was more likely in women who had had infection during previous pregnancies, and genotype E was more likely in those with previous ectopic pregnancies and green vaginal discharge (all p = 0.01). CONCLUSIONS The frequency of C. trachomatis in our population was higher than previously reported worldwide, but within the range reported for Mexico. Genotype E was detected most frequently in the study population. Infection by C. trachomatis and C. trachomatis genotypes K, F, D, and E was strongly associated with multiple sociodemographic, behavioral, and biological factors. C. trachomatis genotype L2 was detected in women with PID.

Abstract
Among the candidate genes for Parkinson's disease (PD), SNCA has replicated association in different populations. Besides other known mutations in the SNCA gene, the rs3857059 variant has also been linked to various neurodegenerative disorders. Therefore, the aim of the present study was to search for association of this variant and sporadic PD in Mexican Mestizo patients. A case-control study was performed including 241 individuals, 106 patients, and 135 healthy controls. Genotyping was performed using real-time PCR. The rs3857059 variant demonstrated an association with PD in Mexican Mestizos (OR = 2.40, CI, 1.1 to 5.1, p = 0.02) under the recessive model. In addition, a gender effect was found for the GG genotype in females (OR = 1.31, CI, 1.01 to 1.7, p = 0.037). This is the first study to confirm an association of the rs3857059 variant with PD and also to show a gender effect. Our data contribute to the elucidation of the link between rs3857059 and susceptibility to PD observed in the Mexican Mestizo population.
