A central concern for the safe provision of ART during the current coronavirus disease 2019 (COVID-19) pandemic is the possibility of vertical transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection through gametes and preimplantation embryos. Unfortunately, data on SARS-CoV-2 viral presence in oocytes of infected individuals are not available to date. We describe the case of two women who underwent controlled ovarian stimulation and tested positive to SARS-CoV-2 infection by PCR on the day of oocyte collection. The viral RNA for gene N was undetectable in all the oocytes analyzed from the two women. [ABSTRACT FROM AUTHOR]

Background: Anxiety and depression are two of the main psychological disorders that affect thousands of people in the world, including university students. This research is justified because it seeks to reevaluate, compare and confirm the psychometric properties and establish the sociodemographic profile of the Anxiety and Depression Disorders Symptom Scale in Peruvian university students. The main objective of this study was to determine the evidence of psychometric properties, and the sociodemographic profile, of the Symptom Scale for Anxiety and Depression Disorders in university students from the region of Piura, Peru., Methods: The sample was determined using proportional, probabilistic sampling that included 6 universities in Piura, Peru, consisting of 1243 participants. The scale has 35 Items within 7 subscales., Results: The results identified that the items fall within the range of ± 1.5 for skewness and kurtosis, except for items 22 and 35. The construct validity, assessed through factor analysis, shows that 100% of the items achieve scores greater than 0.5, with a significance level of less than < 0.001. The goodness-of-fit index through confirmatory factor analysis aligns with the transdiagnostic theoretical model, with scores for CFI and TLI ≥ 0.90, and for RMSEA and SRMR ≤ 0.60. The scale demonstrates adequate composite reliability according to MacDonald's Omega Coefficient (0.959). Furthermore, there is a moderate significant association (p = 0.001; γ = - 0.192) between age, the presence of anxiety and depression symptoms. A strong significant association (p = 0.001; γ = 0.365) is observed between sex and the presence of core symptoms of anxiety and depression., Conclusion: In conclusion, the scale evidence an adequate psychometric consistency, presenting itself as a valid and reliable instrument. Of the university students evaluated, it was generally identified that 24% reach a high level and 50% reach a moderate level of anxiety and depression symptoms. Additionally, being a woman and an adolescent increases the likelihood of presenting elevated levels of the symptoms evaluated by the scale., Competing Interests: Declarations.

Background: Motivation for the study. To contribute to the immunogenic character of soluble and excretion/secretion antigens of Leishmania braziliensis and Leishmania peruviana with the aim of identifying proteins with diagnostic potential., Background: Main findings. The soluble antigen of Leishmania braziliensis has a sensitivity in the detection of ATL of 87.7%, specificity of 100% and a false positive rate of 20% against sera from patients with Chagas disease and 8.3% with mycosis., Background: Implications. Immunoblot can improve the resolution capacity in the serological diagnosis of American tegumentary Leishmaniasis, particularly in patients where the length of the disease and the clinical form make difficult the diagnosis by parasitological methods., Background: This study aimed to determine the performance of Leishmania braziliensis and Leishmania peruviana antigens in the detection of ATL by using serum samples obtained between 2013 - 2016. The obtained soluble and excretion/secretion antigens were transferred to membrane nitrocellulose by immunoblot assay. The evaluation was carried out against sera confirmed for ATL, at a confidence level of 95%, determining that the soluble antigen of Leishmania braziliensis had a sensitivity of 87.7%, specificity of 100% and area under the curve of 0.95; on the other hand, Leishmania peruviana showed values of 92.3%, 95.7% and 0.94, respectively. According to the results, we recommend that the reported immunogenic regions should be characterized and analyzed in order to continue with the development of recombinant and synthetic proteins, aimed at improving the efficiency of the serological diagnosis of the disease.

Suicidal behaviors and constructs are putting at risk the accomplishment of Objective 3 of Agenda 2030 for sustainable development in Spanish-speaking countries. The current study's principal objective is to explain the presence of suicidal ideation and deaths by suicide as a result of the COVID-19 pandemic in Spanish-speaking countries based on a review of the scientific literature. The PRISMA model was used as the main method while considering the criteria of periodicity, language, typology, and country in order to choose the 28 articles that were analyzed from the following three databases: SCOPUS, Web of Science, and ProQuest Coronavirus Research Database. Suicidal ideation and death by suicide exhibited a growth trend during the COVID-19 pandemic, including post-pandemic, especially in kids, adolescents, and young women of university age belonging to lower socioeconomic strata and presenting risk factors like living in rural areas, poor mental health, unemployment, and family death due to COVID-19.

Objectives.: Motivation for the study. There are few studies in Peru on hemolytic uremic syndrome. Main findings. Between the years 2010 to 2020, the age at diagnosis has not changed; however, more patients presented oliguria and required more renal replacement therapy (peritoneal dialysis) compared to previous years. Implications. This syndrome is an important cause of renal damage in children; therefore, its surveillance and notification are necessary. In addition, measures of prevention and early recognition of the disease must be implemented, since this condition is generally caused by consumption of contaminated food.

As the world faces progressive and interconnected global crises and conflicts, the educational expectations set out in the 2030 Agenda for Sustainable Development are in jeopardy. With the COVID-19 pandemic in its third year, the war in Ukraine has exacerbated the food, energy, humanitarian, and refugee crises, all against the backdrop of an unfolding climate emergency. The aim of this research is to analyse the challenges faced by postgraduate programmes in training human talent for sustainable development on the basis of Grounded Theory. To do so, we have used a dialogical intervention through the complementary experiences of authorities of higher-education institutions that live day by day for a fair, quality, and sustainable education. With a naturalistic qualitative method, where the hermeneutic analysis procedure is structured in five phases, and with data from key informants from 9 countries, 20 interviews are obtained with key informants in Latin American and Spanish universities during 2021, according to inclusion criteria such as: belonging to a higher-education institution, with a doctorate degree, with more than 10 years of experience in management, and training in postgraduate programmes. The data are processed through ATLAS.ti9, which allows for the analysis of the key informants' discourses. The findings show that the university institutions that currently offer postgraduate programmes are considering improving the quality of education; the first challenge is to redesign the curricula according to the demands of the current and future world, incorporating technological resources and knowledge of the environment; inter- and transdisciplinary curricula that form enterprising postgraduates with a solid ethical life project; critical, complex, and systemic thinking.

Objectives: To evaluate the in vitro photodynamic activity of aluminum phthalocyanine tetrasulfonate chloride (AlPcClS4) on promastigotes and amastigotes of Leishmania (Viannia) peruviana and Leishmania (Viannia) braziliensis., Materials and Methods: The activity of photodynamic therapy using AlPcClS4 on Leishmania promastigote and amastigotes was determined by the Methyl Thiazole Tetrazolium (MTT) colorimetric method and quantitative PCR, respectively., Results: Photodynamic treatment showed an inhibitory effect on promastigotes, particularly on Leishmania (V.) peruviana, to a lesser extent on Leishmania (V.) braziliensis and also on intracellular forms of both species. At 24 hours post-radiation, using concentrations of 200 μM and 350 μM, the inhibitory effect on Leishmania (V.) peruviana was 72.9% and 73.9% respectively; at 96 hours the inhibitory effect was of 78.8% and 80.6%, respectively. Regarding intracellular forms, the inhibitory effect on Leishmania (V.) peruviana amastigotes was 57.8% at 72 hours post-treatment, using a concentration of 200 μM. The IC50 was 56.5, 50, 44 and 39.7 μM, at 24, 48, 72 and 96 hours post-radiation, respectively., Conclusions: Photodynamic therapy using AlPcClS4 against Leishmania species showed encouraging results, mainly on Leishmania (V.) peruviana, suggesting a potential use as an alternative or complement to the usual treatment of tegumentary leishmaniasis. However, new trials are still required to determine the selectivity index for the intracellular form of the parasite, and to develop methods to facilitate the efficient entry of the molecule into the host cell and the parasite.

In Peru, leishmaniasis is a metaxenic disease that represents a serious public health problem, due to its wide distribution and the number of people in danger of contracting the disease, being the vulnerable population mainly those with low economic resources. The study was conducted from patients who were derived to Peru's National Institute of Health between 2006 and 2011 so that the specialized diagnosis could be carried out. The identification of the species of infectious Leishmania was developed through the analysis of the High-Resolution Melting Analysis obtained from the genomic DNA of promastigotes and amastigotes, which allows to identify the species of Leishmania (Viannia) braziliensis, Leishmania (V.) guyanensis, Leishmania (V.) peruviana as more prevalent, in addition to Leishmania (V.) lainsoni and Leishmania (L.) amazonensis.

Background: The parasite of the genus Leishmania causes a neglected disease known as leishmaniasis, which has different clinical aspects depending on the species that infects the person and the immune response of the patient. The objective was to determine, using molecular biology, the current circulating species of Leishmania in biopsies of different types of cutaneous leishmaniasis (CL) from the endemic district in the region of "Madre de Dios", Peru., Methods: The study's 19 samples were obtained in the Huepethue district in the "Madre de Dios" region from patients who were diagnosed for suspected leishmaniasis infection with three clinical manifestations. These were analyzed using kDNA-PCR, Nested-PCR and HRM-PCR to identify the genus of an infecting parasite as well as its species., Results: kDNA-PCR detected all tests for the genus of Leishmania to be positive, while the Nested-PCR could not detect 20.9% of species (one L . ( V .) braziliensis and three L . ( V .) amazonensis ), and the HRM-PCR detected all species presented in the samples. The most prevalent species was L . ( V .) braziliensis (73.7%), and the clinical manifestations were ulcers (63.2%), superficial scabs (5.3%) and diffuse form (5.3%), followed by L . ( V .) amazonensis (15.8%), manifesting ulcers (15.6%), and L . ( V .) lainsoni (10.5%), manifesting superficial scabs (5.3%) and ulcers (5.3%). L . ( V .) braziliensis , L . ( V .) amazonensis and L . ( V .) lainsoni were detected effectively using HRM-PCR in the samples with different clinical manifestations., Conclusions: Highlighting the findings of a high diversity of Leishmania species using High Resolution Melting PCR in biopsies with different clinical manifestations of cutaneous leishmaniasis.

Premise of the Study: Using phylogeographic analyses to determine the geographic origins of biological invaders is important for identifying environmental adaptations and genetic composition in their native range as well as biocontrol agents among indigenous herbivores. Eurasian watermilfoil (Myriophyllum spicatum) and its hybrid with northern watermilfoil (M. sibiricum) are found throughout the contiguous United States and southern Canada, forming one of the most economically costly aquatic plant invasions in North America, yet the geographic origin of the invasion remains unknown. The objectives of our study included determining the geographic origin of Eurasian watermilfoil in North America as well as the maternal lineage of the hybrids., Methods: DNA sequence data from a cpDNA intron and the nrDNA ITS region were compiled for accessions from 110 populations of Eurasian watermilfoil and hybrids from North America and the native range (including Europe, Asia, and Africa). Datasets were analyzed using statistical parsimony and Bayesian phylogenetics to assess the geographic origin of the invasion., Key Results: The two Eurasian watermilfoil cpDNA haplotypes in North America are also found from China and Korea, but not elsewhere in the native range. These haplotypes did not overlap and were limited in native geographic range. The ovule parent for hybrids can come from either parental lineage, and multiple haplotypes from both parental species were found., Conclusions: The geographic origin of this prolific aquatic plant invasion of North America is in Asia. This provides critical information to better understand the invasion pathway and inform management into the future., (© 2016 Botanical Society of America.)

Introduction: To describe the type and frequency of cutaneous manifestations of leukemia., Methods: Observational, descriptive study. We included patients over 16 years of age, with confirmed diagnosis of leukemia from the Hematology and Dermatology Departments of the outpatient clinic and from in-patients. Patients with bone marrow transplantation were excluded. A complete history and physical examination of the skin and appendages was performed, with biopsy and cultures if required. The cutaneous manifestations were classified as infection or drug-related, leukemic infiltration, associated dermatosis to leukemia and non-specific lesions. Descriptive statistics was employed., Results: We included 142 patients (62 females, 80 males) with the following diagnoses: acute myeloid leukemia (n=36), acute lymphoblastic leukemia (n=52), chronic myeloid leukemia (n=21), chronic lymphocitic leukemia (n=30) and hairy cells leukemia (n=3). 42% of patients (n=60) presented some dermatoses. There were 36 non-specific dermatoses, 21 drug-related, 20 infectious, 3 infiltrative and none associated., Conclusions: Cutaneous manifestations directly related to leukemia are frequent, being the non-specific ones, the most commonly observed. However, a thorough dermatologic examination is important in these patients as part of an overall evaluation.

Clinical manifestations of leishmaniasis are diverse and related to the infecting species, its relationship with the environment and the host immune response. A case of late Andean cutaneous leishmaniasis with extensive manifestation is presented. The case was confirmed through microbiological and immunological studies; identification was performed by cytochrome b gene sequencing and the species was determined as Leishmania (Leishmania) amazonensis. The patient was treated with sodium stibogluconate and at the end of therapy the patient showed clinical improvement of the lesions. It is recommended to consider leishmaniasis in differential diagnosis when treating atypical dermatological chronic ulcers.

This paper reports on a qualitative, exploratory study in 2005, based on interviews with 15 key decision-makers from the Peruvian Ministry of Health responsible for maternal mortality prevention and officials responsible for national data and information on maternal deaths. The main aims were to find out the sources of data and information used by Ministry of Health officials for programme planning and decision-making, whether policies and programmes were informed by the data available, and data flows among central decision-makers within the Ministry and between Ministry and regional and local health centres. Information systems require staff and systems capable of collecting, processing, analysing and sharing data. In Peru, none of these conditions was fulfilled in a homogeneous way. Vertical programmes in the poorest regions had funds for information systems and infrastructure, but limited technical and human resources. Public health workers were overwhelmed with provision of services and not always trained in data collection or informatics. Thus, quality of data collection and analysis varied greatly across regions. Data collection and usage since the study have been improved, reflected in a fall in maternal mortality ratios and women's increased use of maternity services, but efforts to maintain and improve data quality must continue to ensure that initiatives to prevent maternal mortality can be monitored and services improved., (Copyright © 2012 Reproductive Health Matters.

Why is induced abortion common in environments in which modern contraception is readily available? This study analyses qualitative data collected from focus group discussions and in-depth interviews with women and men from low-income areas in five countries--the United States, Nigeria, Pakistan, Peru and Mexico--to better understand how couples manage their pregnancy risk. Across all settings, women and men rarely weigh the advantages and disadvantages of contraception and abortion before beginning a sexual relationship or engaging in sexual intercourse. Contraception is viewed independently of abortion, and the two are linked only when the former is invoked as a preferred means to avoiding repeat abortion. For women, contraceptive methods are viewed as suspect because of perceived side effects, while abortion experience, often at significant personal risk to them, raises the spectre of social stigma and motivates better practice of contraception. In all settings, male partners figure importantly in pregnancy decisions and management. Although there are inherent study limitations of small sample sizes, the narratives reveal psychosocial barriers to effective contraceptive use and identify nodal points in pregnancy decision-making that can structure future investigations.

Although modern contraceptive use in Peru has increased, many women still face unwanted or unplanned pregnancies and abortions remain high despite the illegality of elective pregnancy termination. To improve understanding of how men and women make reproductive decisions, we conducted this study in Lima. Fifty-two 18-37 year old low- and middle-income women and men participated in in-depth interviews and focus groups. Reproductive planning constitutes a worry among participants. The paradigm of contraception, pregnancy, childbearing and pregnancy termination is complex and contained within a context of contradictory pressures toward women: while women feel the need to be autonomous in all realms of their lives, they also need to meet the traditional roles associated with sexuality and childbearing and rearing. The woman, her partner and family members take part in reproductive decisions. However, participants expressed difficulties preventing unwanted pregnancies and social stigma if they resorted to abortion or, interestingly, if they continued a pregnancy when involved in a socially undesirable personal situation. Abortion-related stigma generated fear and guilt in addition to safety concerns given the unsafe, clandestine contexts in which pregnancy termination takes place. Despite these concerns, interviewees often opted for abortion for personal reasons, which were primarily economic.

It is well recognised that unsafe abortions have significant implications for women's physical health; however, women's perceptions and experiences with abortion-related stigma and disclosure about abortion are not well understood. This paper examines the presence and intensity of abortion stigma in five countries, and seeks to understand how stigma is perceived and experienced by women who terminate an unintended pregnancy and influences her subsequent disclosure behaviours. The paper is based upon focus groups and semi-structured in-depth interviews conducted with women and men in Mexico, Nigeria, Pakistan, Peru and the United States (USA) in 2006. The stigma of abortion was perceived similarly in both legally liberal and restrictive settings although it was more evident in countries where abortion is highly restricted. Personal accounts of experienced stigma were limited, although participants cited numerous social consequences of having an abortion. Abortion-related stigma played an important role in disclosure of individual abortion behaviour.

Objective: The aim of this study was to evaluate the extent of lipid peroxidation and the response of the enzymatic and non-enzymatic antioxidant defence system in erythrocytes from full-term and premature infants at birth, after 3 and after 72 h of life., Study Design: Twenty infants were selected and divided in two groups according to their gestational age. Blood samples were taken at birth, at 3 and at 72 h of life, erythrocytes were isolated and the following parameters were measured: fatty-acid profile, coenzyme Q, alpha-tocopherol, hydroperoxides and the activity of the antioxidant enzymes catalase, superoxide dismutase (SOD) and cytosolic glutathione peroxidase (cGPx)., Results: For the three studied periods, several differences between full-term and premature infants were found. Premature children showed a higher concentration of hydroperoxides, a lower level of alpha-tocopherol and lower SOD and cGPx activity (except for cGPx at birth). Moreover, n-3 polyunsaturated fatty-acids percentages (essential for good neonatal development) were higher in full term children throughout all the study., Conclusion: Results suggest a strong imbalance between oxidants and antioxidants in premature infants during their first 72 h of life, a situation which could lead to several pathologies. Therefore, further research is needed, including possible nutritional intervention (with antioxidant therapy, supplementation of essential fatty acids and other dietary constituents) before and after birth.

An understanding of the expression of transgenes in the mammary gland during gestation and lactation is crucial for the use of transgenic mammals as bioreactors. Here we describe the temporal pattern of expression of the endogenous rabbit WAP gene and human erythropoietin (hEPO) transgenes under the control of rabbit WAP promoter and 3' flanking sequences. The endogenous rabbit WAP gene was expressed throughout gestation including the day of mating, as well as during lactation in transgenic rabbits bearing a minigene construct. In non-pregnant cycling females, WAP expression was found independent of transgenic status; however, WAP expression was not detected in non-cycling females. The significance of this new finding is not clear at present. hEPO mRNA was detected in mammary gland biopsies from pregnant transgenic rabbits only on day 28 of gestation. During lactation, transcripts were present in mammary gland biopsy samples taken on days 0, 7, 14 and 21. A sharp decline in the levels of transcripts was found for an hEPOcDNA gene construct at the end of lactation (day 28). Although the levels of hEPO were too low to allow a conclusion to be drawn regarding temporal or position-dependent expression, this finding may reflect an integration position effect.

This case illustrates a unique clinical presentation of primary systemic amyloidosis, namely, overwhelming pneumococcal sepsis. Although there exists a well-established association between hyposplenism and overwhelming bacterial infection, amyloid replacement of the spleen as a primary cause of the hyposplenism has not been reported. Functional hyposplenism in regard to the effect of the spleen on erythrocytes has been reported in cases of diffuse splenic amyloid infiltration. The patient described had a fulminant course and associated disseminated intravascular coagulation, two clinical features more commonly seen in pneumococcemia occurring in asplenic patients as opposed to patients with normal splenic function. He had no predisposing factors, other than amyloid replacement of the spleen, to account for the development of overwhelming pneumococcemia. The immunologic function of the spleen in protection against overwhelming bacterial infection is briefly discussed.
