Mediante la perspectiva de la motivación inicial, la teoría clásica de las necesidades y el modelo de valores individualistas y colectivistas, se analiza el perfil psicosocial de la mujer emprendedora de Mar del Plata, Argentina. Con una base etnometodológica, se administraron cuestionarios sociodemográficos y entrevistas en profundidad según muestreo intencional, con un N = 34. Se realizó análisis de contenido de las respuestas en conformidad con los mencionados modelos teóricos. Las recurrencias muestran que las mujeres desarrollan su emprendimiento con una marcada implicación personal y ante situaciones de criticidad personales o laborales. Así, emprenden tanto por necesidad como por oportunidad, e incorporan una mirada social de especial atención hacia el otro. Desarrollan una característica necesidad de logro, asociada a la superación de obstáculos y el alcance de metas propuestas, aunque también se encuentra necesidad de afiliación, la cual se relaciona con la mirada social antes nombrada. Por último, se han encontrado una conjunción de valores colectivistas asociados a la benevolencia, así como mixtos, asociados al universalismo. Los resultados encontrados, así como su discusión, abren un abanico de preguntas y, a su vez, de posibilidades. El análisis permite concluir que es necesario cuestionarse el espacio de la mujer en el ámbito emprendedor y su necesidad de visibilización.

Abstract
Background: The Nigerian HIV Geriatric Cohort (NHGC) is a longitudinal cohort setup to learn how elderly people living with HIV (EPLHIV) in Nigeria fare, despite not being prioritized by the national treatment program, and to deepen knowledge for their differentiated care and achieve better outcomes. In this paper, we describe data collected on sociodemographic and clinical data from EPLHIV from the inception of Nigeria’s national HIV program to 2018. Methods: Patient-level data spanning the period 2004 to 2018, obtained from comprehensive HIV treatment hospitals, that are supported by four major PEPFAR-implementing partners in Nigeria were used. These 4 entities collaborated as member organizations of the Nigeria Implementation Science Alliance. We defined elderly as those aged 50 years and above. From deidentified treatment records, demographic and clinical data of EPLHIV ≥50-year-old at ART initiation during the review period was examined. Results: A total of 101,652 EPLHIV were analysed. Women accounted for 53,608(53%), 51,037(71%) of EPLHIV identified as married and 33,446(51%) unemployed. Median age was 57.1years (IQR 52–60 years) with a median duration on ART treatment of 4.1years (IQR 1.7–7.1years). ART profile showed that 97,586(96%) were on 1st-line and 66,125(65%) were on TDF-based regimens. Median body mass index (BMI) was 22.2 kg/m 2 (IQR 19.5–25.4kg/m 2 ) with 43,012(55%), 15,081(19%) and 6,803(9%) showing normal (18.5–<25kg/m 2 ), overweight (BMI 25–<30kg/m 2 ) and obese (BMI ≥30kg/m 2 ) ranges respectively. Prevalence of hypertension (systolic-BP >140mmHg or diastolic-BP >90mmHg) was 16,201(21%). EPLHIV Median CD4 count was 381cells/μL (IQR 212-577cells/μL) and 26,687(82%) had a viral load result showing <1000copies/ml within one year of their last visit. As for outcomes at their last visit, 62,821(62%) were on active-in-treatment, 28,463(28%) were lost-to-follow-up and 6,912(7%) died. Poor population death records and aversion to autopsies makes it almost impossible to estimate AIDS-related deaths. Conclusions: This cohort describes the clinical and non-clinical profile of EPLHIV in Nigeria. We are following up the cohort to design and implement intervention programs, develop prognostic models to achieve better care outcomes for EPLHIV. This cohort would provide vital information for stakeholders in HIV prevention, care and treatment to understand the characteristics of EPLHIV.

Abstract
Background: The local recurrence rate in triple negative breast cancer (TNBC) can be as high as 12%.The standard treatment for early-stage TNBC is breast conserving surgery (BCS), followed by postoperative radiotherapy with or without chemotherapy. However, detection of the local recurrence of the disease after radiotherapy is a major issue.Objective: The aim of this study was to investigate the role of dynamic and functional magnetic resonance imaging (MRI) during follow-up after BCS and radiotherapy with/without chemotherapy to differentiate between loco regional recurrence and postoperative fibrosis.Patients and methods: This prospective study was conducted at Oncology, Radiology, and Pathology Departments, Tanta University. It involved 50 patients with early-stage TNBC who were treated with BCS, followed by radiotherapy with/without chemotherapy. The suspected lesions were evaluated during the follow-up period by sonomammography. All patients were subjected to MRI, including conventional sequences, diffusion-weighted imaging (DWI), and dynamic post-contrast study. Results: Ten cases were confirmed as recurrent malignant lesions. After contrast administration, they all exhibited irregular T1 hypodense lesions of variable morphology with diffusion restriction and positive enhancement. Eight cases displayed a type III curve, while two showed a type II curve. Histopathological assessment was consistent with the MRI findings in all eight cases. The combination of the data produced by DWI-MRI and dynamic contrast enhanced (DCE)-MRI resulted in 100%sensitivity, 92.5% specificity, 90.9% positive predictive value, 100% negative predictive value, and 98% accuracy. Conclusion: Combination of DWI-MRI and DCE-MRI could have high diagnostic value for evaluating postoperative changes in patients with TNBC after BCS, followed by radiotherapy with/without chemotherapy.Trial Registrations: not trial to be registered

Abstract
The bacterial genus Enterococcus encompasses 38 species. Two of the most common species are E. faecalis and E. faecium. Recently, however, there has been an increase in clinical reports concerning less prevalent Enterococcus species, such as E. durans, E. hirae, and E. gallinarum. Rapid and accurate laboratory methods are needed to facilitate the identification of all these bacterial species. In the present study, we compared the relative accuracy of matrix-assisted laser desorption/ionisation time-of-flight mass spectrometry (MALDI-TOF MS), VITEK 2, and 16S rRNA gene sequencing using 39 enterococci isolates from dairy samples, and compared the resultant phylogenetic trees. We found that MALDI-TOF MS correctly identified all isolates at the species level except for one, whereas the VITEK 2 system, which is an automated identification system using biochemical characteristics of species, misidentified ten isolates. However, phylogenetic trees constructed from both methods showed all isolates in similar positions. Our results clearly showed that MALDI-TOF MS is a reliable and rapid tool for identifying Enterococcus species with greater discriminatory power than the biochemical assay method of VITEK 2.

Published: November 2020

Abstract
The unprecendented global disruption caused by COVID-19 has exacerbated systemic inequities in healthcare, public health, socioeconomic status, and structural racism. How systematic inequities that are expressed at the intersection of human activities are addressed will influence whether we can control or stop the pandemic. Priotizing collaboration, equity, and investing financial and social capitol into community leadership is an essential part of mitigating and addressing both the short- and long-term repercussions of COVID-19. Through analysis of and evidence from the lived experiences of a national network of African American pastors, the authors recommend four strategies to expedite recovery from the pandemic and to promote enduring beneficial societal change: (1) public health and faith communities should initiate and maintain ongoing relationships that are based on trust; (2) recognition and acknowledgement by agencies and organizations that faith community leaders possess unique knowledge of their communities; (3) inclusion of faith community leaders as full partners when strategizing, decision-making, problem-solving, and policy development sessions occur that affect community wellbeing; and, (4) use of an intersecting approach that recognizes the multifactorial realities of COVID-19 and uses remedies that effectively address existing and new problems in a comprehensive, long-term manner.

Abstract
Background: Emergency departments (EDs) worldwide have been in the epicentre of the novel coronavirus disease (COVID-19). However, the impact of the pandemic and national emergency measures on the number of non-COVID-19 presentations and the assessed acuity of those presentations remain uncertain. Methods: We acquired a retrospective cohort containing all ED visits in a Finnish secondary care hospital during years 2018, 2019 and 2020. We compared the number of presentations in 2020 during the national state of emergency, i.e. from March 16 to June 11, with numbers from 2018 and 2019. Presentations were stratified by New York University Emergency Department Algorithm (NYU-EDA) in order to evaluate changes in presentations with different acuity levels.Results: A total of 27,526 presentations were observed. Compared to previous two years, total daily presentations were reduced by 23 % (from 113 to 87, p<.001). In NYU-EDA classes, Non-Emergent visits were reduced the most by 42 % (from 18 to 10, p<.001). Emergent presentations were reduced by 19 to 28 % depending on the subgroup (p<.001). Number of injuries were reduced by 25 % (from 27 to 20, p<.001). The NYU-EDA distribution changed statistically significantly with 4 percent point reduction in Non-Emergent visits (from 16 % to 12 %, p<.001) and 0.9 percent point increase in Alcohol-related visits (from 1.6 % to 2.5 %, p<.001).Conclusions: We observed a significant reduction in total ED visits in the course of national state of emergency. Presentations were reduced in most of the NYU-EDA groups irrespective of the assessed acuity. A compensatory increase in presentations was not observed in the course of the 3 month lockdown. This implies either reduction in overall morbidity caused by decreased societal activity or widespread unwillingness to seek required medical advice.
Neutrophil-lymphocyte count ratio better predict prognosis than conventional markers in critical patients? A multiple-centered retrospective cohort study
Authors: Zhou Tao , Zheng Nan , Li Xiang , Zhu Dongmei , Han Yi 
Published: November 2020

Abstract
Background: Neutrophil-lymphocyte count ratio (NLCR) has been reported as better indicator of bacteremia than procalcitonin (PCT), and better predictor of mortality than C-reactive protein (CRP) in various medical conditions. However, large controversy remains upon this topic. We compared the efficiency of NLCR with conventional inflammatory markers in predicting the prognosis of critical illness. Methods: We performed a multiple-centered retrospective cohort study consisting of 536 ICU patients with outcomes of survival, 28- and 7-day mortality. NLCR was compared with conventional inflammatory markers such as PCT, C-reactive protein (CRP), serum lactate (LAC), white blood cell, neutrophil and severity score APACHE II (Acute Physiology and Chronic Health Evaluation II) to evaluate the predictive value on outcomes of critical illness. Then receiver operating characteristics (ROC) curves were constructed to assess and compare each marker’s sensitivity and specificity respectively. Results: NLCR values were not differential among survival and mortality groups. Meanwhile remarkable differences were observed upon APACHE II score, CRP, PCT and LAC levels among survival and death groups. ROC analysis revealed that NLCR was not competent to predict prognosis of critical illness. The AUROCs of conventional markers such as CRP, PCT, LAC and APACHE II score were more significant in predicting 28- and 7-day mortality. Conclusions: NLCR is not competent and less reliable than conventional markers CRP, PCT, LAC and APACHE II score in assessing severity and in predicting outcomes of critical illness.

Abstract
Background: ACDF is the main treatment of cervical disease. Adjacent Segment Degeneration (ASD) is the main complication of long-term follow-up of ACDF. we conduct a detailed study of ACDF by means of three-dimensional finite element analysis and find the effect of screw placement and location on the occurrence of ASD.Methods: The cervical computed tomography (CT) data (layer thickness of 0.625 mm) for a 30-year-old healthy male volunteer was collected. All the data were combined to create a C2-7 3D finite element model using Abaqus software. Based on the data and the actual surgical maneuver, a screw positioning model was established, in order to observe the cervical range of motion (ROM) with different positions of screw, as well as the pressure change of the adjacent segment intervertebral disc.Results: The proposed finite element model of cervical spine was effective, and ROM on all directions of C4-C6 segments changed after ACDF surgery. Under the same torque settings, compared with the control group, C2/3 segment rotational ROM increased; C2/3, C3/4 segments lateral flexion ROM also increased. Regarding the influence of screw positioning, it has limited influence on the ROM and The intervertebral disc pressure (IDP), and compared with different horizontal positions, different vertical positions imposed greater influence on the ROM and IDP. Conclusions: For ACDF surgery, positioning the screw at the anterior inferior part of the cervical vertebral body could provide more natural cervical ROM and the least IDP, while maintaining high biomechanical stability, and is more in line with human biomechanical requirements.

Published: November 2020

Abstract
Background: Patients with central lumbar spinal stenosis (CLSS) complain of not only the lower leg symptoms but also low back pain (LBP) simultaneously in many cases. Therefore, patients who undergo decompressive surgery expect recovery from LBP as well as lower leg symptoms, and surgeons who perform decompression surgery are making efforts to improve both symptoms. The objective of this study is to investigate whether decompression surgery can improve low back pain and symptoms of lower limb pain in patients with one level central lumbar spinal stenosis.Methods: The present study included 39 patients who had findings of central lumbar spinal stenosis and underwent decompression surgery due to its corresponding claudication and lower leg radiating pain complaints from 2013 to 2018. Their pain (lower leg radiating pain and low back pain) and functional outcomes (Oswestry Disability Index (ODI), Roland–Morris Disability Questionnaire (RMDQ), and Short Form-36 (SF-36)) were evaluated before surgery and 6 and 12 months after surgery.Results: Mean lower leg radiating pain continuously showed statistically significant improvement (p < 0.05, p = 0.003); however, the clinical significance of differences above minimum clinically important difference (MCID) was up to 6 months. Mean low back pain was 4.72 ± 3.40 before surgery, 2.33 ± 2.27 at 6 months after surgery, and 2.21 ± 2.02 at 12 months after surgery, showing statistically and clinically significant improvement (p < 0.05) up to 6 months after surgery, after which there were no findings of improvement. Conclusion: Decompression surgery for patients with central lumbar spinal stenosis showed clinically significant improvements in lower leg radiating pain and low back pain up to 6 months after surgery and continuous improvements in lower leg radiating pain up to 12 months, but there was no continuous improvement in LBP.

Published: November 2020

Abstract
Background: The objective of this study was to investigate the effects of dietary neutral detergent fiber (NDF) to starch ratios on growth performance, nutrient digestibility, ruminal fermentation, and microbial community patterns. Thirty-six healthy Holstein bulls at nine months of age (averaged 282±37 kg of body weight) were randomly allocated into three treatments: dietary NDF to starch ratio of 1.13, 1.38, and 1.63. Dry matter (DM) intake (DMI), body weight gain, serum biochemical characteristics, hormones, total-tract digestibility, ruminal enzyme activities, ruminal fermentation, and microbial communities were analyzed.Results: Though the DMI and feed efficiency were not affected, the average daily gain (ADG) increased linearly with a decreasing NDF to starch ratio. DM digestibility, ruminal microbial diversity, ruminal amylase activity, propionate and butyrate concentration, serum glucose, acetyl-CoA carboxylase increased linearly with decreasing dietary NDF:starch ratio. The abundance of the predominant ruminal genus, Prevotella 1 (19.00%~31.64%) linearly decreased, while the proportion of two dominant genera (Ruminococcaceae NK4A214 group/4.14%~6.66% and Rikenellaceae RC9 group/5.57%~7.76%) increased with the decreasing NDF:starch ratio. Dry matter intake, digestibility of crude protein, ether extract (EE), NDF and ADF, AST, BUN, TP, NEFA, GH, IGF-1, and insulin were not affected by the dietary NDF:starch ratio.Conclusions: In conclusion, the dietary NDF:starch ratio of 1.13 benefits the weight gain of Holstein bulls. A potential reason might be the regulation of propionate productivity, amylase activity, and physiological metabolism through the change of dominant ruminal microbiota (Prevotella 1, Ruminococcaceae NK4A214 group and Rikenellaceae RC9 group), which might have a beneficial effect on the lipogenesis and body weight gain of Holstein bulls during the fattening period.

Published: November 2020

Abstract
Background: Since December 2019, China has experienced the public health emergency of coronavirus disease, which has expanded globally and is impacting the care of cancer patients. This study evaluated the impact of the pandemic on colorectal cancer (CRC) patients at our center and aimed to share lessons learned with clinics currently experiencing this impact. Methods: We retrospectively collected data on CRC patients admitted between January 1, 2020 and May 3, 2020; the control group comprised patients admitted between January 1, 2019 and May 3, 2019. Results: During the pandemic, outpatient volumes decreased significantly, especially among nonlocal and elderly patients, whereas the number of patients who received chemotherapy and surgery were maintained. During the pandemic, 710 CRC patients underwent curative enterectomy. The proportion of laparoscopic surgery was 49.4%, which was significantly higher than the 39.5% patients who received a laparoscopic surgery during the same period in 2019. The proportion of major complication during the pandemic was not significantly different from that of the control group. The mean hospital stay was significantly longer than that of the control group. Conclusions: CRC patients who are confirmed to be infection-free can receive routine treatment. Using online medical counseling and appropriate identification, treatment and follow-up was effectively maintained. Adjuvant and palliative chemotherapy should not be discontinued. Endoscopic polypectomy, elective, palliative, and multidisciplinary surgeries can be postponed, whereas curative surgery should be performed. For elderly CRC patients, endoscopic surgery and neoadjuvant radiotherapy are recommended.Trial registration: retrospectively registered
