    El presente estudio de investigación tuvo por propósito principal determinar la repercusión de las deudas tributarias en la liquidez de la Municipalidad Distrital de Yambrasbamba, Bongará, 2021. Dicha investigación se enmarcó en el enfoque cuantitativo, con un diseño transversal-no experimental y de tipo correlacional. Como población se consideró el acervo documentario de la municipalidad, siendo la muestra los documentos correspondientes a los estados financieros y deudas tributarias. El análisis documental y guía de análisis documental fueron considerados como técnica e instrumento respectivamente. Los resultados resaltantes fueron: con respecto a las deudas tributarias, éstas se han incrementado por efectos de la pandemia por Covid 12 y que, además son mayores en el primer trimestre; en relación a la liquidez absoluta, el cual es un indicador más preciso que la prueba ácida, en los períodos del 2017 al 2021 es mayor a 0,5, en el segundo trimestre, producto de la pandemia, el indicador bajó a 1,49 ello con respecto al 2021 siendo el más bajo desde al año 2017. Para el último trimestre del año 2021, ha presentado una leve mejoría siendo de 1,83. Se concluye que existe una relación inversa entre deudas tributarias y liquidez de la Municipalidad Distrital de Yambrasbamba, Bongará, en los períodos 2017 al 2021, siendo más evidente en los años 2020 y 2021; siempre se muestran poco significativas.TesisGestión empresarial y emprendimient

    Severe acute respiratory syndrome coronavirus 2 (SARS- CoV- 2), the virus responsible for coronavirus disease 2019 (COVID- 19), is associated with high incidence of multiorgan dysfunction and death. Angiotensin- converting enzyme 2 (ACE2), which facilitates SARS- CoV- 2 host cell entry, may be impacted by angiotensin- converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs), two commonly used antihypertensive classes. In a multicenter, international randomized controlled trial that began enrollment on March 31, 2020, participants are randomized to continuation vs withdrawal of their long- term outpatient ACEI or ARB upon hospitalization with COVID- 19. The primary outcome is a hierarchical global rank score incorporating time to death, duration of mechanical ventilation, duration of renal replacement or vasopressor therapy, and multiorgan dysfunction severity. Approval for the study has been obtained from the Institutional Review Board of each participating institution, and all participants will provide informed consent. A data safety monitoring board has been assembled to provide independent oversight of the project.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/163400/2/jch14011_am.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/163400/1/jch14011.pd

    Background: In an era of shifting global agendas and expanded emphasis on non-communicable diseases and injuries along with communicable diseases, sound evidence on trends by cause at the national level is essential. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) provides a systematic scientific assessment of published, publicly available, and contributed data on incidence, prevalence, and mortality for a mutually exclusive and collectively exhaustive list of diseases and injuries. Methods: GBD estimates incidence, prevalence, mortality, years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life-years (DALYs) due to 369 diseases and injuries, for two sexes, and for 204 countries and territories. Input data were extracted from censuses, household surveys, civil registration and vital statistics, disease registries, health service use, air pollution monitors, satellite imaging, disease notifications, and other sources. Cause-specific death rates and cause fractions were calculated using the Cause of Death Ensemble model and spatiotemporal Gaussian process regression. Cause-specific deaths were adjusted to match the total all-cause deaths calculated as part of the GBD population, fertility, and mortality estimates. Deaths were multiplied by standard life expectancy at each age to calculate YLLs. A Bayesian meta-regression modelling tool, DisMod-MR 2.1, was used to ensure consistency between incidence, prevalence, remission, excess mortality, and cause-specific mortality for most causes. Prevalence estimates were multiplied by disability weights for mutually exclusive sequelae of diseases and injuries to calculate YLDs. We considered results in the context of the Socio-demographic Index (SDI), a composite indicator of income per capita, years of schooling, and fertility rate in females younger than 25 years. Uncertainty intervals (UIs) were generated for every metric using the 25th and 975th ordered 1000 draw values of the posterior distribution. Findings: Global health has steadily improved over the past 30 years as measured by age-standardised DALY rates. After taking into account population growth and ageing, the absolute number of DALYs has remained stable. Since 2010, the pace of decline in global age-standardised DALY rates has accelerated in age groups younger than 50 years compared with the 1990–2010 time period, with the greatest annualised rate of decline occurring in the 0–9-year age group. Six infectious diseases were among the top ten causes of DALYs in children younger than 10 years in 2019: lower respiratory infections (ranked second), diarrhoeal diseases (third), malaria (fifth), meningitis (sixth), whooping cough (ninth), and sexually transmitted infections (which, in this age group, is fully accounted for by congenital syphilis; ranked tenth). In adolescents aged 10–24 years, three injury causes were among the top causes of DALYs: road injuries (ranked first), self-harm (third), and interpersonal violence (fifth). Five of the causes that were in the top ten for ages 10–24 years were also in the top ten in the 25–49-year age group: road injuries (ranked first), HIV/AIDS (second), low back pain (fourth), headache disorders (fifth), and depressive disorders (sixth). In 2019, ischaemic heart disease and stroke were the top-ranked causes of DALYs in both the 50–74-year and 75-years-and-older age groups. Since 1990, there has been a marked shift towards a greater proportion of burden due to YLDs from non-communicable diseases and injuries. In 2019, there were 11 countries where non-communicable disease and injury YLDs constituted more than half of all disease burden. Decreases in age-standardised DALY rates have accelerated over the past decade in countries at the lower end of the SDI range, while improvements have started to stagnate or even reverse in countries with higher SDI. Interpretation: As disability becomes an increasingly large component of disease burden and a larger component of health expenditure, greater research and developm nt investment is needed to identify new, more effective intervention strategies. With a rapidly ageing global population, the demands on health services to deal with disabling outcomes, which increase with age, will require policy makers to anticipate these changes. The mix of universal and more geographically specific influences on health reinforces the need for regular reporting on population health in detail and by underlying cause to help decision makers to identify success stories of disease control to emulate, as well as opportunities to improve.

    Background: Accurate and up-to-date assessment of demographic metrics is crucial for understanding a wide range of social, economic, and public health issues that affect populations worldwide. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 produced updated and comprehensive demographic assessments of the key indicators of fertility, mortality, migration, and population for 204 countries and territories and selected subnational locations from 1950 to 2019. Methods: 8078 country-years of vital registration and sample registration data, 938 surveys, 349 censuses, and 238 other sources were identified and used to estimate age-specific fertility. Spatiotemporal Gaussian process regression (ST-GPR) was used to generate age-specific fertility rates for 5-year age groups between ages 15 and 49 years. With extensions to age groups 10–14 and 50–54 years, the total fertility rate (TFR) was then aggregated using the estimated age-specific fertility between ages 10 and 54 years. 7417 sources were used for under-5 mortality estimation and 7355 for adult mortality. ST-GPR was used to synthesise data sources after correction for known biases. Adult mortality was measured as the probability of death between ages 15 and 60 years based on vital registration, sample registration, and sibling histories, and was also estimated using ST-GPR. HIV-free life tables were then estimated using estimates of under-5 and adult mortality rates using a relational model life table system created for GBD, which closely tracks observed age-specific mortality rates from complete vital registration when available. Independent estimates of HIV-specific mortality generated by an epidemiological analysis of HIV prevalence surveys and antenatal clinic serosurveillance and other sources were incorporated into the estimates in countries with large epidemics. Annual and single-year age estimates of net migration and population for each country and territory were generated using a Bayesian hierarchical cohort component model that analysed estimated age-specific fertility and mortality rates along with 1250 censuses and 747 population registry years. We classified location-years into seven categories on the basis of the natural rate of increase in population (calculated by subtracting the crude death rate from the crude birth rate) and the net migration rate. We computed healthy life expectancy (HALE) using years lived with disability (YLDs) per capita, life tables, and standard demographic methods. Uncertainty was propagated throughout the demographic estimation process, including fertility, mortality, and population, with 1000 draw-level estimates produced for each metric. Findings: The global TFR decreased from 2·72 (95% uncertainty interval [UI] 2·66–2·79) in 2000 to 2·31 (2·17–2·46) in 2019. Global annual livebirths increased from 134·5 million (131·5–137·8) in 2000 to a peak of 139·6 million (133·0–146·9) in 2016. Global livebirths then declined to 135·3 million (127·2–144·1) in 2019. Of the 204 countries and territories included in this study, in 2019, 102 had a TFR lower than 2·1, which is considered a good approximation of replacement-level fertility. All countries in sub-Saharan Africa had TFRs above replacement level in 2019 and accounted for 27·1% (95% UI 26·4–27·8) of global livebirths. Global life expectancy at birth increased from 67·2 years (95% UI 66·8–67·6) in 2000 to 73·5 years (72·8–74·3) in 2019. The total number of deaths increased from 50·7 million (49·5–51·9) in 2000 to 56·5 million (53·7–59·2) in 2019. Under-5 deaths declined from 9·6 million (9·1–10·3) in 2000 to 5·0 million (4·3–6·0) in 2019. Global population increased by 25·7%, from 6·2 billion (6·0–6·3) in 2000 to 7·7 billion (7·5–8·0) in 2019. In 2019, 34 countries had negative natural rates of increase; in 17 of these, the population declined because immigration was not sufficient to counteract the negative rate of decline. Globally, HALE increased from 58·6 years (56·1–60·8) in 2000 to 63·5 years (60·8–66·1) in 2019. HALE increased in 202 of 204 countries and territories between 2000 and 2019

    Background Understanding the magnitude of cancer burden attributable to potentially modifiable risk factors is crucial for development of effective prevention and mitigation strategies. We analysed results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 to inform cancer control planning efforts globally. Methods The GBD 2019 comparative risk assessment framework was used to estimate cancer burden attributable to behavioural, environmental and occupational, and metabolic risk factors. A total of 82 risk-outcome pairs were included on the basis of the World Cancer Research Fund criteria. Estimated cancer deaths and disability-adjusted life-years (DALYs) in 2019 and change in these measures between 2010 and 2019 are presented. Findings Globally, in 2019, the risk factors included in this analysis accounted for 4.45 million (95% uncertainty interval 4.01-4.94) deaths and 105 million (95.0-116) DALYs for both sexes combined, representing 44.4% (41.3-48.4) of all cancer deaths and 42.0% (39.1-45.6) of all DALYs. There were 2.88 million (2.60-3.18) risk-attributable cancer deaths in males (50.6% [47.8-54.1] of all male cancer deaths) and 1.58 million (1.36-1.84) risk-attributable cancer deaths in females (36.3% [32.5-41.3] of all female cancer deaths). The leading risk factors at the most detailed level globally for risk-attributable cancer deaths and DALYs in 2019 for both sexes combined were smoking, followed by alcohol use and high BMI. Risk-attributable cancer burden varied by world region and Socio-demographic Index (SDI), with smoking, unsafe sex, and alcohol use being the three leading risk factors for risk-attributable cancer DALYs in low SDI locations in 2019, whereas DALYs in high SDI locations mirrored the top three global risk factor rankings. From 2010 to 2019, global risk-attributable cancer deaths increased by 20.4% (12.6-28.4) and DALYs by 16.8% (8.8-25.0), with the greatest percentage increase in metabolic risks (34.7% [27.9-42.8] and 33.3% [25.8-42.0]). Interpretation The leading risk factors contributing to global cancer burden in 2019 were behavioural, whereas metabolic risk factors saw the largest increases between 2010 and 2019. Reducing exposure to these modifiable risk factors would decrease cancer mortality and DALY rates worldwide, and policies should be tailored appropriately to local cancer risk factor burden.

    Fueron examinadas 1013 muestras de heces de pollos de engorde de 50 granjas del Municipio Maracaibo, Estado Zulia. El objetivo era determinar la prevalencia de coccidiosis y los factores asociados a esta enfermedad. En el verano (enero, febrero, marzo, abril y parte de mayo) de 645 muestras analizadas, 193 (29.9%) presentaron oquistes y en el invierno (agosto, septiembre y octubre) de 368 muestras de heces, 188 (51.08%) resultaron positivas a Eimeria. Se identificaron 5 especies de Eimeria: Eimeria acervulina, Eimeria máxima, Eimeria tenella, Eimeria necatrix y Eimeria brunetti, esta última ha sido identificada por primera vez en Venezuela. Existe diferencia significativa (P<0.05) al comparar el tipo de cama: viruta, concha de arroz, aserrín y arena. Diferencia (P<0.05) se encontró diferencia significativa (P<0.05) al comparar los grupos de edades y los niveles de infección: en el verano lo pollos más infectados son los de 5 a 6 semanas y en el invierno los de 3 a 4 semanas y los de 7 a 8 semanas. Idénticos resultados se encontraron al comparar el tipo de agua consumida potable y no potable con respecto a la prevalencia. Se observó diferencia significativa al compara el tipo de comedero automático y no automático en relación a sus niveles de infestación en el invierno. Igual diferencia al compara el tamaño de la granja y la prevalencia, en el invierno. En todos los casos la diferencia encontrada fue significativa (P<0.05)25 - 36CuatrimestralA total of 1013 faeces simples from broilers were tested in the Maracaibo county of the Zulia State. Prevalence and associate factors to coccidiosis were studied in the summer or dry season (January, February, March, April and part of May) where 193 samples out of 645 (29.9%) showed oocysts. In the rainy or winter season (August, September and October) 188 samples out of 368 (51.8%) were positive to Eimeria. During the trial were identified 5 Eimeria specie; Eimeria acervulina, Eimeria maxima, Eimeria tenella, Eimeria necatrix and Eimeria brunette, this last species is been identified for the first time in Venezuela. Significant differences (P<0.05) between bird’s density per m² of shed was found for summer and winter seasons. Significant differences (P<0.05) was found comparing bedding items: wood shavings, rice hulls, saw dust and sand. Differences (P<0.05) were found between age’ groups and infection level: in summer broilers 5 to 6 weeks old were the most infected. The same differences for prevalence were found for potable or not potable drinking water. Significant differences for interaction level were found between automatic and manual feeders during the winter season and for size of farm and prevalence in winter

    Purpose: To evaluate dry eye and quantitative and qualitative changes of meibomian glands with meibography in patients with pemphigus. Methods: Twenty left eyes of 20 patients with pemphigus (group 1) and 20 left eyes of 20 age- and sex-matched healthy volunteers (group 2) were enrolled. Dry eye was evaluated with Oxford scale scoring, tear film breakup time, Schirmer 1 tests, and Ocular Surface Disease Index score assessments. Morphological changes and dropout ratio of meibomian glands were evaluated by upper and lower eyelid meibography (SL-D701; Topcon, IJssel, the Netherlands). Meibomian gland dropout ratio was scored for each eyelid from grade 0 (no loss) through grade 3 (lost area >2/3 of the total meibomian gland area). Results: the mean ages of group 1 and group 2 were 51.8 +/- 11.1 (range: 32-73) and 50.4 +/- 9.6 years (range: 32-70), respectively (P= 0.672). Schirmer 1 and tear film breakup time values were lower and Oxford and Ocular Surface Disease Index scores were higher in group 1 when compared with group 2, and the differences were statistically significant (P= 0.01,P< 0.001,P= 0.001, andP< 0.001, respectively). Upper eyelid, lower eyelid, and total eyelid meiboscore values were significantly higher in group 1 (P= 0.005,P= 0.018, andP= 0.002, respectively). Morphological changes in meibomian glands were detected in 16 eyes (80%) among group 1. Conclusions: Between patients with pemphigus and those who were healthy, there were significant differences in the results of dry eye tests and meibomian gland morphology. Patients with pemphigus should be monitored for dry eye and meibomian gland dysfunction and be promptly treated to prevent the serious consequences of dry eye
