Published: July 2022

BackgroundIn dialysis patients, lowering low-density lipoprotein cholesterol (LDL-C) did not provide benefits, which seemed implausible in clinical practice. We hypothesized a U-shaped association between LDL-C and mortality in dialysis patients.MethodsIn this multi-center retrospective real-world cohort study, 3,565 incident Chinese peritoneal dialysis (PD) patients between January 1, 2005, and May 31, 2020, were included. The associations between baseline LDL-C and mortality were examined using cause-specific hazard models.ResultsOf 3,565 patients, 820 died, including 415 cardiovascular deaths. As compared with the reference range (2.26-2.60 mmol/L), both higher levels of LDL-C (&gt; 2.60 mmol/L) and lower levels of LDL-C (&lt; 2.26 mmol/L) were associated with increased risks of all-cause mortality (hazard ratio [HR],1.35, 95% confidence index [CI], 1.09-1.66; HR 1.36, 95%CI, 1.13-1.64) and cardiovascular mortality (HR, 1.31, 95% CI, 1.10-1.72; HR, 1.64; 95% CI, 1.22-2.19). Malnutrition (albumin &lt; 36.0 g/L) modified the association between LDL-C and cardiovascular mortality (P for interaction = 0.01). A significantly increased risk of cardiovascular mortality was observed among patients with malnutrition and lower levels of LDL-C (HR 2.96, 95%CI 1.43-6.12) or higher levels of LDL-C (HR 2.81, 95%CI 1.38-5.72).ConclusionLow and high levels of LDL-C at the start of PD procedure were associated with increased all-cause and cardiovascular mortality risks. Malnutrition may modify the association of LDL-C with cardiovascular mortality.

BackgroundExposure to recurrent infections in childhood was linked to an increased risk of cancer in adulthood. There is also evidence that a history of tonsillectomy, a procedure often performed in children with recurrent infections, is linked to an increased risk of leukemia and Hodgkin lymphoma. Tonsillectomy could be directly associated with cancer risk, or it could be a proxy for another risk factor such as recurrent infections and chronic inflammation. Nevertheless, the role of recurrent childhood infections and tonsillectomy on the one hand, and the risk of breast cancer (BC) in adulthood remain understudied. Our study aims to verify whether a history of tonsillectomy increases the risk of BC in women.MethodsA systematic review was performed using PubMed, Google Scholar, Scopus, Embase, and Web of Science databases from inception to January 25, 2022, to identify the studies which assessed the association between the history of tonsillectomy and BC in females. Odds ratio (OR) was calculated using the random/fixed-effects models to synthesize the associations between tonsillectomy and BC risk based on heterogeneity.ResultsEight studies included 2252 patients with breast cancer of which 1151 underwent tonsillectomy and 5314 controls of which 1725 had their tonsils removed. Patients with a history of tonsillectomy showed a higher subsequent risk of developing BC (OR, 1.24; 95% CI: 1.11-1.39) as compared to patients without a history of tonsillectomy. Influence analyses showed that no single study had a significant effect on the overall estimate or the heterogeneity.ConclusionsOur study revealed that a history of tonsillectomy is associated with an increased risk of breast cancer. These findings underscore the need for frequent follow-ups and screening of tonsillectomy patients to assess for the risk of BC.

BackgroundPeritoneal carcinomatosis (PC) of gastric cancer indicates a poor outcome and is mainly diagnosed by staging laparoscopy (SL). This study was designed to develop a risk stratification model based on the number of risk factors to exempt low-risk patients from unnecessary SL.MethodsThis was a retrospective cohort study based on a single institution between January 2015 and December 2019. SL is indicated for patients of advanced locoregional stage, and clinicopathologic characteristics of 535 consecutive patients were included. PC-associated variables were identified by logistic regression analysis. A risk stratification model based on the number of risk factors was constructed, and we defined its predictive value with a receiver operating characteristic (ROC) curve and negative predictive value.ResultsIn total, 15.9% of included patients were found to have PC during SL. Borrmann type IV, elevated CA125, and tumour diameter ≥5 cm were independent risk factors of PC. These three factors combined with cT4 were selected as predictive factors, and the number of predictive variables was significantly related to the possibility of PC (2.0%, 12.8%, 20.0%, 54.2%, and 100%, respectively). When the cutoff value is more than one predictive factor, the negative predictive value is 98.0%, with an area under the curve of 0.780. This model could exempt 29.8% of unnecessary SL compared to the indication of the current NCCN guideline.ConclusionsWe constructed a simple model to predict the probability of PC using the number of predictive factors. It is recommended that patients without any of these factors should be exempt from SL.

Introduction: The current literature has not yet provided a definitive conclusion on the best emergency groin hernia repair. The aim of this study was first to compare the short and long-term outcomes between open preperitoneal and anterior approach in emergency groin hernia repair and second to identify risk factors for postoperative complications, mortality, and recurrence.Materials and Methods: This retrospective cohort study included patients who underwent emergency groin hernia repair between January 2010 and December 2018. Short and long-term outcomes were analyzed comparing approach and repair techniques. The predictors of complications and mortality were investigated using multivariate logistic regression. Cox regression multivariate analysis were used to explore risk factors of recurrence.Results: A total of 316 patients met the inclusion criteria. The most widely used surgical techniques were open preperitoneal mesh repair (34%) and mesh plug (34%), followed by Lichtenstein (19%), plug and patch (7%) and tissue repair (6%). Open preperitoneal mesh repair was associated with lower rates of recurrence (p = 0.02) and associated laparotomies (p &lt; 0.001). Complication and 90-day mortality rate was similar between the techniques. Multivariable analysis identified patients aged 75 years or older (OR, 2.08; 95% CI, 1.14–3.80; p = 0.016) and preoperative bowel obstruction (OR, 2.11; 95% CI, 1.20–3.70; p = 0.010) as risk factors for complications and Comprehensive Complication Index ≥26.2 as risk factor for 90-day mortality (OR, 44.76; 95% CI, 4.51–444.59; p = 0.01). Female gender was the only risk factor for recurrence.Conclusion: Open preperitoneal mesh repair may be superior to other techniques in the emergency setting, because it can avoid the morbidity of associated laparotomies, with a lower long-term recurrence rate.

La contaminación por reactivos mineros en el recurso aire plantea una de las más severas problemáticas que comprometen al bienestar de medio ambiente y salud a nivel global y local. Portovelo es una de las ciudades mineras más antiguas de Ecuador. Esta activada gran escala todavía utiliza procesos que no cuentan con un adecuado plan de manejo y mitigación de los desechos denominados escoria en el proceso de recuperación del oro. En este estudio, se recolectaron y evaluaron datos de varios puntos ubicados en una misma ciudad, se consideró los analitos de las exposiciones de MPS comparando la presencia o ausencia de minas y su incidencia en la concentración de mercurio (Hg), Arsénico (As), Selenio (Se) y Plomo (Pb) en el ambiente expulsados en el proceso de fundición y refinación. Los resultados revelaron que en la ciudad de Portovelo existen gran cantidad de MPS proveniente de las expulsiones en los procesos mineros. Los análisis señalan que las estaciones de monitoreo superan el límite máximo permisible estipulado en el Acuerdo Ministerial 097-A de 1mg/cm2 *30dias; mientras que, haciendo referencia a las directrices de la Organización Mundial de la Salud, todos los sitios analizados superan el límite máximo permisible de 0,5mg/cm2 *30dias. La presencia de caseríos y poblaciones con recurrentes actividades antropogénicas sugieren que el aire que entra en contacto con ellos al respirar tenga en su composición estas sustancias antes mencionadas, pudiéndose dar así consecuencias en la salud de las poblaciones aleñadas.

Tuberkulosis merupakan suatu penyakit menular langsung yang disebabkan oleh bakteri TB yaitu Myobacterium Tuberculosis. Sampai saat ini, Tuberkulosis (TBC) masih menjadi tantangan besar untuk pemerintah Indonesia. Untuk kepentingan diagnosis dengan cara pemeriksaan sputum mikroskopis langsung, terduga pasien TB diperiksa contoh uji sputum dengan pewarnaan Ziehl Neelsen. Namun, di beberapa daerah di Indonesia, jauhnya fasilitas kesehatan terkadang mengharuskan sampel BTA mengalami penundaan pemeriksaan karena melalui proses pengiriman terlebih dahulu. Tujuan penelitian ini adalah untuk mengetahui adanya pengaruh perbedaan suhu dan lama penyimpanan sputum terhadap jumlah Bakteri Tahan Asam. Desain penelitian ini adalah desain penelitian eksperimental laboratorium dengan rancangan acak lengkap (RAL). Penelitian dilakukan dengan 5 perlakuan yaitu penyimpanan selama 0 jam, 24 jam pada suhu 2-8oC, 24 jam pada suhu 25oC, 48 jam pada suhu 2-8oC dan 48 jam pada suhu 25oC. Berdasarkan pengamatan mikroskopis dan pengolahan data, diperoleh hasil p value > 0,05 maka Ho diterima dan Ha ditolak. Dari hasil tersebut dapat disimpulkan bahwa tidak terdapat pengaruh dari perbedaan suhu dan lama penyimpanan terhadap jumlah BTA +.

Tuberculosis is a direct infectious disease caused by the TB bacteria, named Myobacterium tuberculosis. Until now, Tuberculosis (TBC) is still a big challenge for the Indonesian government. For the purpose of diagnosis by direct microscopic examination of sputum, suspected TB patients are examined for sputum samples with Ziehl Neelsen staining. However, in some areas in Indonesia, the distance from health facilities sometimes requires that Acid-Fast Bacilli samples undergo a delay in examination because they go through the delivery process first. Therefore, the purpose of this study was to determine the effect of differences in temperature and storage time on the amount of Acid-Fast Bacilli +. The design of this study is a laboratory experimental research design with a completely randomized design. The study was conducted with 5 treatments, that stored for 0 hours, 24 hours at a temperature of 2-8oC, 24 hours at a temperature of 25oC, 48 hours at a temperature of 2-8oC and 48 hours at a temperature of 25oC. After microscopic observation and data processing, the results obtained p value > 0.05, then Ho is accepted and Ha is rejected. From these results it can be concluded that there is no effect of differences in temperature and storage time on the amount of acid-fast bacilli +.
Viudas y Huérfanos: Mortalidad diferencial en el sector central de la Puna de Jujuy a fines del siglo XVIII.
Authors: Peña Aguilera Daniela , Alfaro Gómez Emma 
Published: July 2022

Resumen
A partir de dos registros de población de fines del siglo XVIII para Casabindo y Cochinoca, Puna de Jujuy, se realiza un análisis detallado sobre los grupos familiares asentados en cada uno de ellos. Se toma en cuenta individuos y grupos de parentesco del Censo Virreinal de 1778/79 y del Padrón de tributarios de 1786. Los resultados obtenidos revelan una población numerosa y estable, reflejada en un importante porcentaje de individuos presente en ambos registros y en una significativa cantidad de nacimientos. En contraste, se advierte en el último documento un sensible aumento de viudos/as, huérfanos, familiares a cargo y la ausencia de individuos correspondientes a grupos etarios específicos. Esta situación se podría vincular a modo hipotético, con la incidencia de una peste, epidemia u otras circunstancias adversas ocurridas en el trascurso, ocasionando un patrón de mortalidad diferencial sobre el cual no se encuentran evidencias documentales.
SUBJECTIVITY AND SOCIAL RECOGNITION: THEORETICAL AND EMPIRICAL PERSPECTIVES ON THE VALUE OF NON-FORMAL EDUCATION FROM THE PERSPECTIVE OF YOUNG PEOPLE
Authors: Grimm Sandra Biewers , Weis Daniel , Latz Anita 
Published: July 2022

Due to its principles of voluntariness and openness, and because of its diverse offer of experiential and subject?related educational opportunities, open youth work is increasingly seen as having a special potential in supporting the acquisition of key competences and life skills. But which educational opportunities are meant here and what form of education are we talking about here at all? These are the questions addressed by the qualitative?reconstructive study "Educational Experiences in Non?formal Settings", which is being conducted at the Centre for Childhood and Youth Research (CCY) at the University of Luxembourg. The study examines the subjective educational experiences of young people in open youth work on the basis of ethnographic observations in youth centers, in problem-centered interviews and group discussions with young people as well as a supplementary quantitative survey. The study is based on an understanding of education that follows the tradition of subject?scientific theory (v. Humboldt, Koller) as well as the recognition theory (Honneth) and discusses education with concepts of self?determination and maturity in dealing with social norms and routines. The starting point of this consideration is that education can be determined as the transformation of the relationship to the self and the world. It is also linked to the theoretical work of Albert Scherr (1996), who defines the development of self?awareness, self?esteem, self?determination and thus ultimately subjectivity as the central educational goals of youth work. Empirically, it is thus not primarily a matter of investigating processes of knowledge acquisition, but rather of describing "innovative moments in the development of individual ways of thinking and acting (Koller, 2018, p.112). The results of the data analysis show a differentiated description of youth?related educational occasions and marks small?scale experiences of the appropriation of personal, social and everyday life references. They also highlight moments of expanding young people's ways of thinking, possibilities of action and dispositions in the context of open youth work. The high importance of social recognition as a basic prerequisite for educational processes (among the young people involved) becomes visible.
AND THEN I ASK THE COMMUNITY - NURSING PROFESSIONAL IDENTITY DEVELOPMENT IN VIRTUAL COMMUNITIES OF PRACTICE
Authors: Hommel Linda 
Published: July 2022

Virtual Communities of Practice in the context of nursing - understood as interest-based associations of people who exchange nursing knowledge and nursing experiences using online platforms - also develop their significance in case of professional identity development. "What does it mean to be a nursing professional?" is a central question in the nursing education context, in which the foundation for the development of a professional identity is laid. While findings already exist regarding the development of nursing professional identity in the context of different learning places (nursing school and nursing practice), it’s still open, how the participation in virtual Communities of Practice can influence the development of professional identity already in the context of nursing education. This research project explores the following questions: Which nursing related themes show up in the context of virtual Communities of Practice? How the process of nursing professional identity development is influenced by the participation of nursing scholars in virtual Communities of Practice? Which meaning the learners attribute to the participation in virtual Communities of Practice with regard to the formation of nursing professional identity? The goal of the study is to develop the virtual Community of Practice as a learning space that supports the process of identity formation already in nursing education. Furthermore, the findings will be used to shed light on the medial reality of nursing scholars and to derive curricular consequences. Within the framework of a netnographic research design, data collection will be conducted via field observations of community activities and will additionally be supplemented by focused individual interviews with community members. In the context of data analysis, the documentary method will be used in addition to the production of dense descriptions.

Focusing on the cultivation of talents' innovation ability by the professional course system of unmanned aerospace vehicle (UAV) technology, we will explore the talent cultivation mode from the perspective of education ecosystem, analyze the low enthusiasm for independent learning in talent cultivation, how to reflect the job demand, closed-loop talent evaluation and lifelong learning how to implement and other issues. Innovative education models, curriculum system design, training quality assurance and other methods and mechanisms driven by job competency requirements are studied, which actively coordinate to "producers", "decomposers" and "consumers" in the innovative education ecosystem and "inorganic environment" and other major factors, aiming to explore the innovation ability training of high-quality innovative talents. Combining scientific literacy, innovative talents with "knowledge-ability-quality" are cultivated. Combined with the innovative education model of the education ecosystem, the innovation ability of talents will be improved. Combined with talent evaluation feedback and training exchange mechanism, the improvement of iterative education ecological cycle can be realized.
