feasibility of the recruitment methods, and the ability to retain FSW participants across multiple study visits. A follow-up randomized study with a larger number of participants is planned to test the efficacy of the intervention among high-risk populations of women engaging in transactional sex.The COVID-19 outbreak, caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), was first identified in China, and it has quickly become a global threat to public health due to its rapid rate of transmission and fatalities. Angiotensin-converting enzyme 2 (ACE2) has been identified as a receptor that mediates the entry of SARS-CoV-2 into human cells, as in the case of severe acute respiratory syndrome coronavirus (SARS-CoV). Several studies have reported that ACE2 expression is higher in Leydig, Sertoli and seminiferous ductal cells of males, as well as in ovarian follicle cells of females, suggesting possible potential pathogenicity of the coronavirus in the reproductive system. Higher ACE2 expression in the human placenta and reports of vertical transmission of SARS-CoV-2 among clinical cases have increased the relevance of further studies in this area. This review focuses on the interaction between SARS-CoV-2 and the ACE2 receptor and speculates on the mechanistic interplay in association with male and female reproductive physiology. In addition, based on the available literature, we discuss the alleged sex differences in terms of the infectivity of SARS-CoV-2, which is claimed greater among males, and further explore the physiological role of ACE2 and 17β-oestradiol for the same.Integrating healthcare into education settings represents a promising model to address complex health problems in disadvantaged communities through improving access to health and social services. One such example of an effective school-based health hub is the Our Mia Mia (OMM) Wellbeing Hub, located in a primary school in Nowra and servicing a community experiencing significant socioeconomic disadvantage. The efficacy of OMM rests on its success in facilitating access to services by removing the barriers of cost and transport and establishing connection to community. The OMM fosters collaborations between health professionals and educators to coordinate holistic treatment and implement appropriate student supports in a timely manner. The support of key individuals and groups, in addition to the flexibility of the model, has allowed the hub to pivot and adapt to meet the changing needs of its community, particularly as challenges pertaining to bureaucracy, financial sustainability and community mistrust have presented themselves. Future directions for the OMM hub, and the possibility of adapting and translating school-based healthcare delivery models in other disadvantaged communities, is discussed.ObjectivesHealthcare expenditure is growing at an unsustainable rate in developed countries. A recent scoping review identified several alternative healthcare delivery models with the potential to improve health system sustainability. Our objective was to obtain input and consensus from an expert Delphi panel about which alternative models they considered most promising for increasing value in healthcare delivery in Australia and to contribute to shaping a research agenda in the field.MethodsThe panel first reviewed a list of 84 models obtained through the preceding scoping review and contributed additional ideas in an open round. In a subsequent scoring round, the panel rated the priority of each model in terms of its potential to improve health care sustainability in Australia. Consensus was assumed when ≥50% of the panel rated a model as (very) high priority (consensus on high priority) or as not a priority or low priority (consensus on low priority).ResultsEighty-two of 149 invited participants (55%) repr research is needed to demonstrate the effectiveness and cost-effectiveness of some of these models.Glioma is the most common and lethal malignant intracranial tumor. Long noncoding RNAs (lncRNAs) have been identified as pivotal regulators in the tumorigenesis of glioma. However, the role of lncRNA urothelial carcinoma-associated 1 (UCA1) in glioma genesis is still unknown. The purpose of this study was to investigate the underlying function of UCA1 on glioma genesis. The results demonstrated that UCA1 was upregulated in glioma tissue and indicated a poor prognosis. UCA1 knockdown induced by si-UCA1 significantly suppressed the proliferative, migrative, and invasive activities of glioma cell lines (U87 and U251). Bioinformatics analysis and luciferase reporter assay verified the complementary binding within UCA1 and miR-122 at the 3-UTR. Functional experiments revealed that UCA1 acted as an miR-122 sponge to modulate glioma cell proliferation, migration, and invasion via downregulation of miR-122. Overall, the present study demonstrated that lncRNA UCA1 acts as an endogenous sponge of miR-122 to promote glioma cell proliferation, migration, and invasion, which provides a novel insight and therapeutic target in the tumorigenesis of glioma.Colon cancer (CC) is the third most common cancer worldwide. Emodin is an anthraquinone-active substance that has the ability to affect tumor progression. Our study aims to explore the effects and the relevant mechanism of emodin on the invasion and migration of CC in vitro and in vivo. In our study, we found that emodin inhibited the invasion and migration abilities of RKO cells and decreased the expression of matrix metalloproteinase-7 (MMP-7), MMP-9, and vascular endothelial growth factor (VEGF) in a dose-dependent manner. Further research suggested that emodin inhibited EMT by increasing the mRNA level of E-cadherin and decreasing the expression of N-cadherin, Snail, and -catenin. selleckchem Emodin also significantly inhibited the activation of the Wnt/-catenin signaling pathway by downregulating the expression of related downstream target genes, including TCF4, cyclin D1, and c-Myc. A Wnt/-catenin signaling pathway agonist abolished the effect of emodin on EMT and cell mobility, suggesting that emodin exerted its regulating role through the Wnt/-catenin pathway. The CC xenograft model was established to study the antitumor efficiency of emodin in vivo. The in vivo study further demonstrated that emodin (40 mg/kg) suppressed tumor growth by inhibiting EMT via the Wnt/-catenin signaling pathway in vivo. Taken together, we suggest that emodin inhibits the invasion and migration of CC cells in vitro and in vivo by blocking EMT, which is related with the inhibition of the Wnt/-catenin signaling pathway.Colon cancer is one of the most lethal varieties of cancer. Chemotherapy remains as one of the principal treatment approaches for colon cancer. The anticancer activity of procaine (PCA), which is a local anesthetic drug, has been explored in different studies. In our study, we aimed to explore the anticancer effect of PCA on colon cancer and its underlying mechanism. The results showed that PCA significantly inhibited cell viability, increased the percentage of apoptotic cells, and decreased the expression level of RhoA in HCT116 cells in a dose-dependent manner (p less then 0.05 or p less then 0.01). Moreover, PCA increased the proportion of HCT116 cells in the G1 phase as well as downregulated cyclin D1 and cyclin E expressions (p less then 0.05). In addition, we found that PCA remarkably inhibited cell migration in HCT116 cells (p less then 0.01). However, all these effects of PCA on cell proliferation, apoptosis, and migration were significantly reversed by PCA+pc-RhoA (p less then 0.05 or p less then 0.01). PCA also significantly decreased the levels of p-ERK, p-p38MAPK, and p-FAK, but PCA+pc-RhoA rescued these effects. Furthermore, the ERK inhibitor (PD098059), p38MAPK inhibitor (SB203580), and FAK inhibitor (Y15) reversed these results. These data indicate that PCA inhibited cell proliferation and migration but promoted apoptosis as well as inactivated the ERK/MAPK/FAK pathways by regulation of RhoA in HCT116 cells.Anesthesia in rhesus macaques is required for many procedures. Although ketamine is the backbone of most anesthetic protocols, tolerance to the drug can develop, resulting in the need for higher doses to provide sufficient restraint. Combination with other drugs, such as α-agonists, can be ketamine-sparing, providing for sufficient restraint at lower ketamine doses. In addition, because α-agonists are reversible, recovery from anesthesia has the potential to be much shorter. We hypothesized that use of a low dose of ketamine with a high dose of dexmedetomidine, an α2 receptor selective agonist, in male and female rhesus macaques less than 15 y of age would provide adequate anesthesia for short procedures and that recovery would be faster than in macaques given a higher dose of ketamine (10 mg/kg) alone. We found that the combination, in conjunction with atipamezole for reversal, provided smooth induction of anesthesia and significantly shorter recovery time than did ketamine alone, with no significant effects of sex. The combination of low dose ketamine and high dose dexmedetomidine also provided a 30-min window of anesthesia with analgesia sufficient for mild to moderately painful procedures.

The aim of this study was to examine whether exposure to previous traumatic events is a risk factor for stress reactions during this pandemic. Capitalizing on a 29-year longitudinal study of Israeli ex-prisoners of war (ex-POWs) and combat veterans, we examined whether captivity is a risk factor for fear of coronavirus disease 2019 (COVID-19) and COVID-19-induced acute stress disorder (COVID-19 ASD) beyond the effects of combat exposure and other stressful life events. In addition, we examined the contribution of captivity experiences (severity of captivity, experience of solitary confinement, and suffering during captivity) and veterans' appraisal of the impact of their war-related experiences on adjustment to the current quarantine and isolation to fear of COVID-19 and COVID-19 ASD.

One-hundred-and-twenty Israeli ex-POWs from 1973 Yom Kippur War and 65 matched controls (combat veterans from the same war) filled out self-report questionnaires 18 (T1), 35 (T2), 42 (T3), and 47 (T4) years after the war.

Findings revealed that although ex-POWs and controls did not differ in their level of exposure to COVID-19, ex-POWS reported higher levels of fear of COVID-19 and COVID-19 ASD than controls. Suffering during captivity, measured at 1991, and participants' appraisal of the extent to which their war-related experiences affected adjustment to COVID-19 were significantly associated with fear of COVID-19 and COVID-19 ASD.

The findings of the study demonstrate the long-term effects of exposure to traumatic experiences (captivity) during young adulthood on adjustment to an unrelated collective stress, such as COVID-19, 40 years later.

Major depressive disorder (MDD), bipolar disorder (BD), and schizophrenia (SCZ) are associated with impaired intelligence that predicts poor functional outcomes. However, little is known regarding the extent and severity of intelligence decline, that is, decreased present intelligence quotient (IQ) relative to premorbid levels, across psychiatric disorders and which clinical characteristics affect the decline.

Premorbid IQ, present IQ, and intelligence decline were compared across patients with MDD (n=45), BD (n=30), and SCZ (n=139), and healthy controls (HCs; n=135). Furthermore, we investigated which factors contribute to the intelligence decline in each diagnostic group.

Significant differences were observed in premorbid IQ, present IQ, and intelligence decline across the diagnostic groups. Patients with each psychiatric disorder displayed lower premorbid and present IQ and more intelligence decline than HCs. Patients with SCZ displayed lower premorbid and present IQ and more intelligence decline than patients with MDD and BD, while there were no significant differences between patients with MDD and BD.
