BACKGROUND
Zimbabwe antenatal HIV prevalence rate is 16.1%. HIV-positive pregnant adolescent girls and young women (AYW) are at high risk to experience perinatal mental health challenges, attributed to a combination of factors including HIV status, stigma and perinatal depression. Perinatal depression and stigma among AYW is understudied in Zimbabwe and may affect short- and long-term health of HIV positive mothers and their children, and can impact treatment adherence.
METHODS
Qualitative data was gathered from four focus group discussions with (2 urban and 2 rural) PMTCT providers ( = 17). Focus group discussions were also conducted among AYW clients ( = 20) from two clinics in Mashonaland East.
RESULTS
Qualitative analyses identified patterns related to: (1) drop out and loss to follow up, (2) retention and adherence, (3) recurring feelings of internalized stigma; and (4) acceptability of potential MH interventions. MH services are not available and AYW have limited access to adherence counseling (1-2 times at onset). Psychological support was not available at either clinic, despite both providers and clients perceiving high rates of stigma, discrimination, and challenges with disclosure. Challenges related to long waits for ART distribution and gaps in disclosure support emerged as barriers. Providers noted that AYW present as anxious (non-diagnosed), and attribute depression to those clients who are lost to follow up, stating lack of time to screen for MH related issues or actively refer them for services. Challenges related to the ability to provide strong advice and support for disclosure also emerged among providers.
CONCLUSIONS
This study can contribute to policy and practice recommendations to better integrate MH into HIV services and develop person-centered service models for HIV positive AYW. HIGHLIGHTSPerinatal adolescents and young women (AYW) living with HIV have gaps in retention and care in the current Zimbabwe PMTCT service model.Mental health stigma must be addressed to integrate mental health into HIV services.HIV providers are aware of the need to provide mental health support to reduce loss to follow-up.Mental health screening and referrals for services are not part of standard care for perinatal HIV positive AYW in Zimbabwe.Linkages between disclosure and AYW mental health was identified as a challenge by HIV providers.Context responsive interventions can support integration of mental health screening, services, and referrals.

Unfolding the mysteries of heterogeneity from a high-resolution perspective: integration analysis of single-cell multi-omics and spatial omics revealed functionally heterogeneous cancer cells in ccRCC.
The genomic landscape of clear cell renal cell carcinoma (ccRCC) has a considerable intra-tumor heterogeneity, which is a significant obstacle in the field of precision oncology and plays a pivotal role in metastasis, recurrence, and therapeutic resistance of cancer. The mechanisms of intra-tumor heterogeneity in ccRCC have yet to be fully established. We integrated single-cell RNA sequencing (scRNA-seq) and transposase-accessible chromatin sequencing (scATAC-seq) data from a single-cell multi-omics perspective. Based on consensus non-negative matrix factorization (cNMF) algorithm, functionally heterogeneous cancer cells were classified into metabolism, inflammatory, and EMT meta programs, with spatial transcriptomics sequencing (stRNA-seq) providing spatial information of such disparate meta programs of cancer cells. The bulk RNA sequencing (RNA-seq) data revealed high clinical prognostic values of functionally heterogeneous cancer cells of three meta programs, with transcription factor regulatory network and motif activities revealing the key transcription factors that regulate functionally heterogeneous ccRCC cells. The interactions between varying meta programs and other cell subpopulations in the microenvironment were investigated. Finally, we assessed the sensitivity of cancer cells of disparate meta programs to different anti-cancer agents. Our findings inform on the intra-tumor heterogeneity of ccRCC and its regulatory networks and offers new perspectives to facilitate the designs of rational therapeutic strategies.

Review
Natural killer (NK) cells make only a small fraction of immune cells in the human body, however, play a pivotal role in the fight against cancer by the immune system. They are capable of eliminating abnormal cells via several direct or indirect cytotoxicity pathways in a self-regulating manner, which makes them a favorable choice as a cellular therapy against cancer. Additionally, allogeneic NK cells, unlike other lymphocytes, do not or only minimally cause graft-versus-host diseases opening the door for an off-the-shelf therapy. However, to date, the production of NK cells faces several difficulties, especially because the critical process parameters (CPPs) influencing the critical quality attributes (CQAs) are difficult to identify or correlate. There are numerous different cultivation platforms available, all with own characteristics, benefits and disadvantages that add further difficulty to define CPPs and relate them to CQAs. Our goal in this contribution was to summarize the current knowledge about NK cell expansion CPPs and CQAs, therefore we analyzed the available literature of both dynamic and static culture format experiments in a systematic manner. We present a list of the identified CQAs and CPPs and discuss the role of each CPP in the regulation of the CQAs. Furthermore, we could identify potential relationships between certain CPPs and CQAs. The findings based on this systematic literature research can be the foundation for meaningful experiments leading to better process understanding and eventually control.

Review
In the treatment of coronavirus infections, it is important not only to understand the course of the disease, but also to understand what is happening in the human body, especially in the circulatory system, that is, which disorders lead to deterioration and further complications. Hemostasis disorder in COVID-19 plays an important role in the etiology and clinical manifestations of the disease. The ability to identify factors and risk groups for the development of thrombotic complications, the ability to dynamically interpret peripheral blood parameters and coagulograms, knowledge of diagnostic criteria for possible hemostasis disorders (for example, DIC syndrome, sepsis-associated coagulopathy, antiphospholipids, hemophagocytosis and hypercoagulation syndrome) are necessary to determine the indications for the test. Differentiated prescribing of clinically justified therapy (including anticoagulants and blood components) is important, which determines the complexity of treatment and prognosis for patients with COVID-19. This article is a review of the literature on the topic of hemostasis disorders in elderly and senile patients with mesenteric thrombosis in COVID 19 over the past few years.

Research on the condition of the lungs in senile people is an urgent task. This is due to the fact that degenerative or age-associated changes in the respiratory system play an important role in the formation of senile asthenia syndrome and a decrease in the age-related viability of the body as a whole. CT-scans of patients aged 80-90 years were analyzed (n=31). Age-associated changes were evaluated: the presence of linear fibrosis, increased pulmonary pattern by the type of reticular (reticular) changes, the presence of gross fibrous reticular changes with cystic cavities and air bullae (by the type of «cellular lung»), as well as the presence of pulmonary emphysema. Most naturally, senile people show changes characteristic of linear pulmonary fibrosis and emphysema. The progression of the process leads to diffuse reticular changes in the interalveolar and intersegmental septa and, in adverse cases, to the formation of gross changes in the type of «cellular lung». Fibro-emphysematous changes are significantly more common in men. A microbiological study of the microbiota of the lower respiratory tract in elderly people was also carried out (n=16). When studying the microbiocenosis of the lower respiratory tract in elderly people, the following data were obtained: resident microflora was found in 71% and clinically significant microorganisms were found in 29%.

Review
[Markers of inflammation with decreased functionality in the cognitive and psychological domains of individual vitality in middle-aged and elderly patients with metabolic syndrome.].
Metabolic syndrome is a group of disorders that are closely related to both the risk of developing type 2 diabetes mellitus and cardiovascular diseases, and generally leading to the phenomenon of premature aging of the body. Excessive accumulation of adipose tissue contributes to the development of chronic immune inflammation and oxidative stress, which are both precursors to various disorders, such as insulin resistance, arterial hypertension and dyslipidemia, but also trigger inflammatory processes in patients. An increasing number of studies support the importance of chronic immune inflammation in the pathogenesis of metabolic syndrome, as pro-inflammatory markers such as TNF-α, IL-1β, IL-6, monocyte chemotactic protein-1 and growth of vascular endothelium. Among a wide range of cytokines, monocyte chemotactic protein-1 is considered one of the most important chemokines, which activates monocytes and other immune cells actively involved in inflammation. Another important point of chronic immune inflammation is its impact on the mental health of patients with metabolic syndrome. Increased levels of anxiety and depression are associated with levels of pro-inflammatory cytokines produced by adipose tissue, which ultimately has an adverse effect on the cognitive status of patients.

Review
Communication is considered as one of the basic human needs. For a long time, loneliness and social isolation were mainly considered as a psychosocial problem. However, in the recent years, there has been increasing evidence of the possible impact of loneliness and social isolation on the development and clinical course of somatic diseases. Research objectives were studying and analysis of current literature data about the medical consequences of loneliness and social isolation in the elderly cases. An analysis of the literature data shows that loneliness and social isolation affect not only the psycho-emotional status of elderly patients, but also their physical health. It has been shown that the number of available social connections affects the development and clinical course of diabetes mellitus, cardiovascular diseases, and outcomes of the brain stroke, immune system reactions, average life expectancy, and the risk of death caused by any causes. It has been established that the influence of social ties on the risk and clinical course of chronic non-communicable diseases is comparable to the effect of such generally accepted risk factors like smoking, alcohol consumption, physical inactivity, hypertension, obesity, hypercholesterolemia, environmental pollution, as well as various medical interventions (vaccination, drug therapy, etc.). Social isolation affects the risk of hospitalization and the frequency of outpatient care, poor socialization increases the risk of death from a heart attack. The results of the study show that loneliness and social isolation of the elderly cases have certain medical consequences that need to be taken into account when managing such patients.
