Authors: Aggarwal Ashutosh Nath , Agarwal Ritesh , Dhooria Sahajal , Prasad Kuruswamy Thurai , Sehgal Inderpaul Singh , Muthu Valliappan 
Published: October 2021

Objective
The proportion of COVID-19 patients having active pulmonary tuberculosis, and its impact on COVID-19 related patient outcomes, is not clear. We conducted this systematic review to evaluate the proportion of patients with active pulmonary tuberculosis among COVID-19 patients, and to assess if comorbid pulmonary tuberculosis worsens clinical outcomes in these patients.

Methods
We queried the PubMed and Embase databases for studies providing data on (a) proportion of COVID-19 patients with active pulmonary tuberculosis or (b) severe disease, hospitalization, or mortality among COVID-19 patients with and without active pulmonary tuberculosis. We calculated the proportion of tuberculosis patients, and the relative risk (RR) for each reported outcome of interest. We used random-effects models to summarize our data.

Results
We retrieved 3,375 citations, and included 43 studies, in our review. The pooled estimate for proportion of active pulmonary tuberculosis was 1.07% (95% CI 0.81%-1.36%). COVID-19 patients with tuberculosis had a higher risk of mortality (summary RR 1.93, 95% CI 1.56–2.39, from 17 studies) and for severe COVID-19 disease (summary RR 1.46, 95% CI 1.05–2.02, from 20 studies), but not for hospitalization (summary RR 1.86, 95% CI 0.91–3.81, from four studies), as compared to COVID-19 patients without tuberculosis.

Conclusion
Active pulmonary tuberculosis is relatively common among COVID-19 patients and increases the risk of severe COVID-19 and COVID-19-related mortality.
Employing marine invertebrate cell culture media for isolation and cultivation of thraustochytrids
Authors: Qarri Andy , Rinkevich Yuval , Rinkevich Baruch 
Published: October 2021

Abstract
Thraustochytrids, a common group of marine eukaryotic protists, have drawn considerable scientific and industrial interest due to their ability to synthesize high levels of bioactive compounds, including polyunsaturated fatty acids, docosahexaenoic acid, squalene and carotenoids, and their new applications for biofuels. The pharmaceutical and industrial potential of thraustochytrids necessitate effective isolation of new strains and establishment of axenic cultures. To date, existing isolation protocols have used baiting and direct plating methods to generate axenic cultures with varied media compositions that contain peptone and yeast extracts as nitrogen sources, glucose as carbon source, seawater and antibiotics. Here we reveal a new approach for the isolation of thraustochytrids from tissues of marine invertebrates using (a) primary cell cultures in a liquid medium containing basal medium, 50% artificial seawater, vitamins, proteins and antibiotics, and (b) cultivation in the same cell culture medium. Using the colonial tunicate Botryllus schlosseri as a model system, thraustochytrid cells thrived in the medium from the day of extraction, grew and proliferated for the next five weeks (five-passages, up to 1.9 × 106 cells ml−1 in passage 5; 1.45-fold multiplication week−1). This new approach for isolation and cultivation of axenic thraustochytrid cultures enables the isolation of new species with promising bioactive compounds.
Individual differences in word senses
Authors: Ramsey Rachel E. 
Published: October 2021

AbstractIndividual differences and polysemy have rich literatures in cognitive linguistics, but little is said about the prospect of individual differences in polysemy. This article reports an investigation that sought to establish whether people vary in the senses of a polysemous word that they find meaningful, and to develop a novel methodology to study polysemy. The methodology combined established tools: sentence-sorting tasks, a rarely used statistical model of inter-participant agreement, and network visualisation. Two hundred and five English-speaking participants completed one of twelve sentence-sorting tasks on two occasions, separated by a delay of two months. Participants varied in how similarly they sorted the sentences as compared to other participants, and mean agreement across all 24 tasks did not meet an established threshold of acceptable agreement. Between the two test phases, inter-participant agreement varied to a significant but trivial degree. Networks generated for each dataset varied in the degree to which they captured all participants’ responses. This variation correlated with inter-participant agreement. The data collectively suggest that word senses may be subject to individual differences, as is the case in other linguistic phenomena. The methodology proved replicable and has a promise as a useful tool for studying polysemy.
Sklar’s theorem, copula products, and ordering results in factor models
Authors: Ansari Jonathan , Rüschendorf Ludger 
Published: October 2021

Abstract
We consider a completely specified factor model for a risk vector X = (X
1, . . ., Xd
), where the joint distributions of the components of X with a risk factor Z and the conditional distributions of X given Z are specified. We extend the notion of *-product of d-copulas as introduced for d = 2 and continuous factor distribution in Darsow et al. [6] and Durante et al. [8] to the multivariate and discontinuous case. We give a Sklar-type representation theorem for factor models showing that these *-products determine the copula of a completely specified factor model. We investigate in detail approximation, transformation, and ordering properties of *-products and, based on them, derive general orthant ordering results for completely specified factor models in dependence on their specifications. The paper generalizes previously known ordering results for the worst case partially specified risk factor models to some general classes of positive or negative dependent risk factor models. In particular, it develops some tools to derive sharp worst case dependence bounds in subclasses of completely specified factor models.
C-minimal topological groups
Authors: Xi Wenfei , Shlossberg Menachem 
Published: October 2021

Abstract
In this paper, we study topological groups having all closed subgroups (totally) minimal and we call such groups c-(totally) minimal. We show that a locally compact c-minimal connected group is compact. Using a well-known theorem of [P. Hall and C. R. Kulatilaka,
A property of locally finite groups,
J. Lond. Math. Soc. 39 1964, 235–239] and a characterization of a certain class of Lie groups, due to [S. K. Grosser and W. N. Herfort,
Abelian subgroups of topological groups,
Trans. Amer. Math. Soc. 283 1984, 1, 211–223], we prove that a c-minimal locally solvable Lie group is compact.
It is shown that a topological group G is c-(totally) minimal if and only if G has a compact normal subgroup N such that

G
/
N

G/N

is c-(totally) minimal.
Applying this result, we prove that a locally compact group G is c-totally minimal if and only if its connected component

c
⁢

(
G
)

c(G)

is compact and

G
/
c

⁢

(
G
)

G/c(G)

is c-totally minimal.
Moreover, a c-totally minimal group that is either complete solvable or strongly compactly covered must be compact. Negatively answering [D. Dikranjan and M. Megrelishvili,
Minimality conditions in topological groups,
Recent Progress in General Topology. III,
Atlantis Press, Paris 2014, 229–327, Question 3.10 (b)], we find, in contrast, a totally minimal solvable (even metabelian) Lie group that is not compact.

Abstract

Objectives
To explore the outcomes of threading the Patient-Centered Integrated Behavioral Health Care Principles and Tasks Checklist (AIMS Checklist) into the curricula and experiential setting.

Methods
A qualitative exploratory descriptive method with a constructivist epistemology was used to obtain in-depth student perspectives about their understanding, experiences, and process of applying Integrated Collaborative Care within the clinical setting.

Results
24 Psychiatric Mental Health Nurse Practitioner Students (PMHNP) were divided into focus groups that yielded seven main themes and seven subthemes. Three of the identified themes emerged as opportunities for curriculum enhancement.

Conclusions
The checklist was found to be a valuable tool in not only evaluating collaborative care but in closing the gap between didactic and clinical education in fostering student-preceptor discussion.
Utilizing the Four Tenets of Osteopathic Medicine as an intersectional framework for approaching sexual orientation and gender identity disclosure as a provider
Authors: Counce Timothy L. , Ko Amy , Martinez Anthony D. , Rivera Jenna M. , Browne Carol , Solis Linda 
Published: October 2021

Abstract
The Lesbian, Gay, Bisexual, Transgender, Queer, Intersex, and other (LGBTQI+) community continues to experience health inequity and unmet needs. This manuscript examines the application of the Four Tenets of Osteopathic Medicine (FTOM) during a patient’s self-disclosure of their sexual orientation and/or gender identity to the provider, also known as coming out. Tenet One discusses the interplay between intersectionality and coming out. Tenet Two elucidates how coming out moves toward a balance of homeostasis and self-healing. Tenet Three examines how structure and function can be understood on a personal level and how society influences coming out. Tenet Four explains the resources available to facilitate the previously forementioned changes. By applying the Four Tenets, the provider may more readily understand what “coming out” means on personal and social levels and what implications they may have on their patients’ health.

Abstract
Type 2 diabetes mellitus (T2DM) is a strong risk tfactor for osteosarcopenia. The relationship between musculoskeletal index and β-cell function remains controversial. We aimed to describe the clinical characteristics of osteosarcopenia and to explore the association between osteosarcopenia and β-cell function, as well as insulin resistance in patients with T2DM. A total of 150 middle-aged and older nonobese patients with T2DM were recruited. Bone mineral density (BMD) and body composition were measured by the dual-energy X-ray absorptiometry scanner. The homeostasis model assessment of insulin resistance and Matsuda index were used to evaluate insulin resistance status. β-Cell function was estimated by the area under the curve insulin/glucose (AUC-Ins/Glu) and the area under the curve C-peptide/glucose (AUC-CP/Glu). T2DM patients with osteosarcopenia had lower body mass index, waist circumference, body fat percentage, AUC-Ins/Glu, and AUC-CP/Glu. Both AUC-Ins/Glu (OR = 0.634, P = 0.008) and AUC-CP/Glu (OR = 0.491, P = 0.009) were negatively associated with the presence of osteosarcopenia. Multivariate linear regression analysis showed that β-cell function was positively associated with the skeletal muscle mass index, whereas it showed no correlation with lumbar or hip BMD. β-Cell function is associated with osteosarcopenia in middle-aged and older nonobese patients with T2DM. These findings suggest that β-cell function might be a protective factor against osteosarcopenia.

The review is a comprehensive study for the comparison of Au and Ag NPs synthesis, properties and applications in different fields.
A Precuneal Causal Loop Mediates External and Internal Information Integration in the Human Brain
Authors: Lyu Dian , Pappas Ioannis , Menon David K. , Stamatakis Emmanuel A. 
Published: October 2021

Human brains interpret external stimuli based on internal representations. One untested hypothesis is that the default-mode network (DMN), widely considered responsible for internally oriented cognition, can decode external information. Here, we posit that the unique structural and functional fingerprint of the precuneus (PCu) supports a prominent role for the posterior part of the DMN in this process. By analyzing the imaging data of 100 participants performing two attention-demanding tasks, we found that the PCu is functionally divided into dorsal and ventral subdivisions. We then conducted a comprehensive examination of their connectivity profiles and found that at rest, both the ventral PCu (vPCu) and dorsal PCu (dPCu) are mainly connected with the DMN but also are differentially connected with internally oriented networks (IoN) and externally oriented networks (EoN). During tasks, the double associations between the v/dPCu and the IoN/EoN are correlated with task performance and can switch depending on cognitive demand. Furthermore, dynamic causal modeling (DCM) revealed that the strength and direction of the effective connectivity (EC) between v/dPCu is modulated by task difficulty in a manner potentially dictated by the balance of internal versus external cognitive demands. Our study provides evidence that the posterior medial part of the DMN may drive interactions between large-scale networks, potentially allowing access to stored representations for moment-to-moment interpretation of an ever-changing environment.SIGNIFICANCE STATEMENTThe default-mode network (DMN) is widely known for its association with internalized thinking processes, e.g., spontaneous thoughts, which is the most interesting but least understood component in human consciousness. The precuneus (PCu), a posteromedial DMN hub, is thought to play a role in this, but a mechanistic explanation has not yet been established. In this study we found that the associations between ventral PCu (vPCu)/dorsal PCu (dPCu) subdivisions and internally oriented network (IoN)/externally oriented network (EoN) are flexibly modulated by cognitive demand and correlate with task performance. We further propose that the recurrent causal connectivity between the ventral and dorsal PCu supports conscious processing by constantly interpreting external information based on an internal model, meanwhile updating the internal model with the incoming information.
Cardiolipin remodeling enables protein crowding in the inner mitochondrial membrane

Published: October 2021

AbstractMitochondrial cristae are extraordinarily crowded with proteins, which puts stress on the bilayer organization of lipids. We tested the hypothesis that the high concentration of proteins drives the tafazzin‐catalyzed remodeling of fatty acids in cardiolipin, thereby reducing bilayer stress in the membrane. Specifically, we tested whether protein crowding induces cardiolipin remodeling and whether the lack of cardiolipin remodeling prevents the membrane from accumulating proteins. In vitro, the incorporation of large amounts of proteins into liposomes altered the outcome of the remodeling reaction. In yeast, the concentration of proteins involved in oxidative phosphorylation (OXPHOS) correlated with the cardiolipin composition. Genetic ablation of either remodeling or biosynthesis of cardiolipin caused a substantial drop in the surface density of OXPHOS proteins in the inner membrane of the mouse heart and Drosophila flight muscle mitochondria. Our data suggest that OXPHOS protein crowding induces cardiolipin remodelling and that remodeled cardiolipin supports the high concentration of these proteins in the inner mitochondrial membrane.
Strategy Implementation: Does Hierarchy Culture Matter in Licensed Professional Societies in East Africa
Authors: Njagi Anne 
Published: October 2021

Purpose: This study is aimed at establishing hierarchy and strategy relationship in registered professional bodies in Kenya.
Design/Method/Approach: The dependent variable was measured through policy implementation, resource assessment and motivation. Hierarchy culture as an independent variable was measured through dominant characteristic and management of employees. Using a descriptive design approach, the study collected a return of 132 responses from a target of 168 in professional bodies of Kenya. The study set up a null hypothesis to be tested using a linear regression model to establish the relationship between dependent and independent variables.
Findings: For hierarchy constructs, it was established that there was a significant correlation between strategy implementation and dominant characteristics r = .316, p < .05 with the management of employees r = .288, p < .05.
Theoretical Implications: This paper expanded the body of research on organizational culture by showing that there is a significant relationship between the hierarchy culture and strategy implementation with both dominant characteristics and management of employees showing positive effects for the relationship.
Originality/Value: This research shows that the organizations that are most successful in the market have a strong hierarchy culture within their environment. Therefore, professional bodies must at least have a mechanism of ensuring hierarchy culture within the organization.
Research Limitations/Future Research: The study only looked at the association between hierarchy culture and strategy implementation. Future studies should investigate the relationship between strategy implementation and other dimensions of an organizational culture.

A circulação das ka’aguy heté reguá no litoral do Rio Grande do Sul: as criações naturais originárias de uso comum e a complementariedade entre aldeias Mbya Guarani
Authors: Printes Rafaela Biehl , Coelho-de-Souza Gabriela Peixoto 
Published: October 2021

O modo de ser e viver Guarani está diretamente interligado ao manejo das espécies vegetais, em especial às sementes, e espécies animais, cujos usos revelam outras lógicas de interagir e usufruir desses recursos, ao visualizarem, por meio de múltiplas dimensões, a co-existência entre todos os seres. Esta cosmo-ecologia considera que as ka’aguy heté reguá (criações naturais originárias) de uso comum são uma dádiva divina, acarretando em regras culturais de uso que permitem a manutenção das espécies e o acesso a todos os Guarani. Neste contexto, o estudo, por meio de pesquisa etnográfica, analisou as ka’aguy heté reguá, suas condições de acesso, usos e fluxos em uma porção do Yvy rupá (território originário) situada no litoral do Rio Grande do Sul. As criações naturais que se destacam nesta porção do Yvy Rupá são nove, além das sementes. As tekoá estão situadas em uma região de transição entre o Planalto, onde ocorre o manejo da ka’a (erva-mate), o kuri’y (pinhão), tregüem (xaxim), takua’i, (taquara-mansa), ygary (cedro), e a Planície Costeira do Rio Grande do Sul, onde ocorre o kapi’i reimbé (capim santa-fé), pindó (jerivá), jata’i (butiá), passando pelas encostas, onde é manejado o kurupika’y (pau-leiteiro), jejy (juçara) e mantida as ma’ety (plantações naturais – sementes originárias). Cada tekoá compõe um pequeno fragmento desta porção do Yvy Rupá, resguardando alguma das ka’aguy heté reguá, acessada por todos, mobilizando o constante movimento. Dessa forma, as trocas mútuas e contínuas destas criações naturais tecem laços fortes de reciprocidade interaldeã, abrangendo dimensões permeadas de sentidos espirituais e cosmo-ecológicos.

COAGULANT-FLOCCULANT FROM SECONDARY RESOURCES FOR TREATMENT OF INDUSTRIAL AND MUNICIPAL WASTEWATER
Authors: Shablovski Vladimir , Tuchkoskaya Alla , Rukhlya Vladimir , Pap Olga 
Published: October 2021

Coagulants and flocculants are used almost at all drinking water supply facilities, wastewater treatment plants of municipal and industrial enterprises in Belarus and Ukraine to intensify and increase the efficiency of the processes of purification, clarification and discoloration of water and wastewater. Mainly as coagulants aluminum and iron salts are used, as flocculants - active silicic acid, starch, cellulose derivatives, polyacryloamide, etc.
Sulfuric acid treatment of alumina-containing raw materials allows, in the course of one process, to obtain a mixture of active substances - salts of aluminum, iron, active SiO2. In this case, there is no need to separate the salt from suspended particles and colloidal silicic acid. The presence of suspended dispersed particles in the active substance, as well as colloidal silicic acid and its salts, enhances and accelerates coagulation. The resulting solution, along with aluminum sulfate, contains silicic acid, which acts as a flocculant in the process of water purification. In addition, the processed products also contain ferrous sulfate, in the presence of which a better coagulation result is achieved.
Industrial tests of the coagulant-flocculant were carried out in order to purify wastewater from oil products. The test results showed that the effectiveness of the coagulant-flocculant in reducing the content of oil products in wastewater is comparable to the currently used aluminum sulfate.
The effectiveness of the developed coagulant-flocculant for the purification of drinking water was evaluated in comparative tests with a coagulant “Polvak-68” in the mode of trial coagulation on a laboratory flocculator. The research results are showed that the value of all parameters characterizing the contamination of the source water are highty decreasing for experimental coagulant-flocculant in compare with regular product.
