Cost-Effectiveness and Budget Impact Analysis of the Implementation of Differentiated Service Delivery Models for HIV Treatment in Mozambique: a Modelling Study.

Introduction: In 2018, the Mozambique Ministry of Health launched guidelines for implementing differentiated service delivery models (DSDMs) to optimize HIV service delivery, improve retention in care, and ultimately reduce HIV-associated mortality. The models were fast-track, 3-month antiretrovirals dispensing, community antiretroviral therapy groups, adherence clubs, family approach and three one-stop shop models: adolescent-friendly health services, maternal and child health, and tuberculosis. We conducted a cost-effectiveness analysis and budget impact analysis to compare these models to conventional services.

Impact of differentiated service delivery models on 12-month retention in HIV treatment in Mozambique: an interrupted time-series analysis.

Background: HIV treatment has been available in Mozambique since 2004, but coverage of, and retention in, antiretroviral therapy (ART) remain suboptimal. Therefore, to increase health system efficiency and reduce HIV-associated mortality, in November, 2018, the Ministry of Health launched national guidelines on implementing eight differentiated service delivery models (DSDMs) for HIV treatment. We assessed the effect of this implementation on retention in ART 12 months after initiation, and explored the associated effects of COVID-19.

An RNA-based feed-forward mechanism ensures motor switching in oskar mRNA transport.

Regulated recruitment and activity of motor proteins is essential for intracellular transport of cargoes, including messenger ribonucleoprotein complexes (RNPs). Here, we show that orchestration of oskar RNP transport in the Drosophila germline relies on interplay between two double-stranded RNA-binding proteins, Staufen and the dynein adaptor Egalitarian (Egl). We find that Staufen antagonizes Egl-mediated transport of oskar mRNA by dynein both in vitro and in vivo.

High molecular weight adiponectin as a biomarker of hypertension in children and adolescents with obesity.

Lower HMW (high molecular weight) adiponectin levels are associated with obesity, insulin resistance, and metabolic syndrome in children and adolescents. However, data on HMW levels in pediatric population with hypertension are lacking. This study aimed to examine the association and predictive capacity of HMW levels, HMW/HOMA-IR, and HMW/APN ratio with hypertension in obese children and adolescents.

Managers' and providers' perspectives on barriers and facilitators for the implementation of differentiated service delivery models for HIV treatment in Mozambique: a qualitative study.

Introduction: In 2018, Mozambique's Ministry of Health launched a guideline for a nationwide implementation of eight differentiated service delivery models to optimize HIV service delivery and achieve universal coverage of HIV care and treatment. The models were (1) Fast-track, (2) Three-month Antiretrovirals Dispensing, (3) Community Antiretroviral Therapy Groups, (4) Adherence Clubs, (5) Family-approach, and three one-stop shop models for (6) Tuberculosis, (7) Maternal and Child Health, and (8) Adolescent-friendly Health Services. This study identified drivers of implementation success and failure across these differentiated service delivery models.

Protecting the gains: analysis of HIV treatment and service delivery programme data and interventions implemented in 19 African countries during COVID-19.

Introduction: The potential disruption in antiretroviral therapy (ART) services in Africa at the start of the COVID-19 pandemic raised concern for increased morbidity and mortality among people living with HIV (PLHIV). We describe HIV treatment trends before and during the pandemic and interventions implemented to mitigate COVID-19 impact among countries supported by the US Centers for Disease Control and Prevention (CDC) through the President's Emergency Plan for AIDS Relief (PEPFAR).

Methods: We analysed quantitative and qualitative data reported by 10,387 PEPFAR-CDC-supported ART sites in 19 African countries between October 2019 and March 2021.

MCM complexes are barriers that restrict cohesin-mediated loop extrusion.

Eukaryotic genomes are compacted into loops and topologically associating domains (TADs), which contribute to transcription, recombination and genomic stability. Cohesin extrudes DNA into loops that are thought to lengthen until CTCF boundaries are encountered. Little is known about whether loop extrusion is impeded by DNA-bound machines.

Profiling cellular diversity in sponges informs animal cell type and nervous system evolution.

The evolutionary origin of metazoan cell types such as neurons and muscles is not known. Using whole-body single-cell RNA sequencing in a sponge, an animal without nervous system and musculature, we identified 18 distinct cell types. These include nitric oxide–sensitive contractile pinacocytes, amoeboid phagocytes, and secretory neuroid cells that reside in close contact with digestive choanocytes that express scaffolding and receptor proteins.

Protocol for active safety monitoring of a cohort of patients using a dolutegravir-based antiretroviral regimen in Mozambique.

Introduction: Dolutegravir-based antiretroviral therapy (ART) is increasingly being used as the preferred first-line regimen for the treatment of HIV in low-income and middle-income countries. The National Program for the Control of STI/HIV/AIDS in Mozambique has planned a phased introduction of the tenofovir/lamivudine/dolutegravir (TLD) regimen. In 2019, concerns about a potential safety signal identified with dolutegravir identified in the results of the Tsepamo study, conducted in Botswana, led the National Directorate of Pharmacy and the National Program for the Control of STI/HIV/AIDS to establish an active pharmacovigilance surveillance system among newly placed patients on a TLD regimen.

Outcomes of patients on second- and third-line ART enrolled in ART adherence clubs in Maputo, Mozambique.

Objectives: Adherence clubs (AC) offer patient-centred access to antiretroviral therapy (ART) while reducing the burden on health facilities. AC were implemented in a health centre in Mozambique specialising in patients with a history of HIV treatment failure. We explored the impact of AC on retention in care and VL suppression of these patients.

Drosophila Atg9 regulates the actin cytoskeleton via interactions with profilin and Ena.

Autophagy ensures the turnover of cytoplasm and requires the coordinated action of Atg proteins, some of which also have moonlighting functions in higher eukaryotes. Here we show that the transmembrane protein Atg9 is required for female fertility, and its loss leads to defects in actin cytoskeleton organization in the ovary and enhances filopodia formation in neurons in Drosophila. Atg9 localizes to the plasma membrane anchor points of actin cables and is also important for the integrity of the cortical actin network.

Nuclear Pores Assemble from Nucleoporin Condensates During Oogenesis.

The molecular events that direct nuclear pore complex (NPC) assembly toward nuclear envelopes have been conceptualized in two pathways that occur during mitosis or interphase, respectively. In gametes and embryonic cells, NPCs also occur within stacked cytoplasmic membrane sheets, termed annulate lamellae (AL), which serve as NPC storage for early development. The mechanism of NPC biogenesis at cytoplasmic membranes remains unknown.

Do-not-resuscitate and treatment limitation decisions - Six years of experience from a Portuguese General Intensive Care Unit.

Objective: Treatment limitation, as well as do-not-resuscitate (DNR) directives, are difficult but important to improve patients' quality of life and minimize dysthanasia. We aimed to study the approach to withholding, withdrawal, and DNR decisions, patients' characteristics, and process documentation in a general Intensive Care Unit (ICU) in Portugal.

Methods: A retrospective analysis of data regarding the limitation of treatment decisions collected from previously-designed forms and complemented by medical record consultation.

Live cell imaging reveals 3'-UTR dependent mRNA sorting to synapses.

mRNA transport restricts translation to specific subcellular locations, which is the basis for many cellular functions. However, the precise process of mRNA sorting to synapses in neurons remains elusive. Here we use Rgs4 mRNA to investigate 3'-UTR-dependent transport by MS2 live-cell imaging.

Staufen2-mediated RNA recognition and localization requires combinatorial action of multiple domains.

Throughout metazoans, Staufen (Stau) proteins are core factors of mRNA localization particles. They consist of three to four double-stranded RNA binding domains (dsRBDs) and a C-terminal dsRBD-like domain. Mouse Staufen2 (mStau2)-like Drosophila Stau (dmStau) contains four dsRBDs.

Variable expression and penetrance in Portuguese families with Familial Hypercholesterolemia with mild phenotype.

Familial hypercholesterolemia is an Mendelian dominant disorder characterized by defects of the low density lipoprotein receptor (LDLR) that result in a defective removal of LDL from plasma, which promotes deposition of cholesterol in the skin (xanthelasma), tendons (xanthomas), and arteries (atherosclerosis). Diagnosis severe clinical phenotype FH with Dutch Lipid Clinic Network Criteria, encompassing history of premature ASCVD, tendon xanthomas, and a family history of hypercholesterolemia and premature ASCVD in relatives is rare in the Portuguese FH patients. There is a variability of the phenotype in FH individuals with clinical diagnosis or genetic mutation (carriers and patients) probably due to environmental factors in the last century, a Mediterranean diet, or a diet without fat food, trans fat food, no smoking, no sedentary life that can interfere with our metabolism, or are consequences of polygenic, epigenetic, acquired defects, modifiers genes and beta-globin asymptomatic carriers.

One-step enzymatic modification of RNA 3' termini using polymerase θ.

Site-specific modification of synthetic and cellular RNA such as with specific nucleobases, fluorophores and attachment chemistries is important for a variety of basic and applied research applications. However, simple and efficient methods to modify RNA such as at the 3' terminus with specific nucleobases or nucleotide analogs conjugated to various chemical moieties are lacking. Here, we develop and characterize a one-step enzymatic method to modify RNA 3' termini using recombinant human polymerase theta (Polθ).
