RESUMO
Hepatic ischemia/reperfusion (I/R) injury can arise as a complication of liver surgery and transplantation. Sirtuin 1 (SIRT1), an NAD+-dependent deacetylase, modulates inflammation and apoptosis in response to oxidative stress. SIRT1, which is regulated by p53 and microRNA-34a (miR-34a), can modulate non-alcoholic fatty liver disease, fibrosis and cirrhosis. Since carbon monoxide (CO) inhalation can protect against hepatic I/R, we hypothesized that CO could ameliorate hepatic I/R injury by regulating the miR-34a/SIRT1 pathway. Livers from mice pretreated with CO, or PFT, a p53 inhibitor, displayed reduced production of pro-inflammatory mediators, including TNF-α, iNOS, interleukin (IL)-6, and IL-1ß after hepatic I/R injury. SIRT1 expression was increased by CO or PFT in the liver after I/R, whereas acetylated p65, p53 levels, and miR-34a expression were decreased. CO increased SIRT1 expression by inhibiting miR-34a. Both CO and PFT diminished pro-inflammatory cytokines production in vitro. Knockdown of SIRT1 in LPS-stimulated macrophages increased NF-κB acetylation, and increased pro-inflammatory cytokines. CO treatment reduced miR-34a expression and increased SIRT1 expression in oxidant-challenged hepatocytes; and rescued SIRT1 expression in p53-expressing or miR-34a transfected cells. In response to CO, enhanced SIRT1 expression mediated by miR-34a inhibition protects against liver damage through p65/p53 deacetylation, which may mediate inflammatory responses and hepatocellular apoptosis. The miR-34a/SIRT1 pathway may represent a therapeutic target for hepatic injury.

OBJECTIVE: We (a) describe the development of a hospital-school-community telepartnership (HSCT) program targeting suicidality crisis response implemented in the immediate aftermath of the COVID-19 pandemic, (b) report on service utilization outcomes from the first year and half of program implementation, and (c) share early lessons learned and implications for future directions. METHOD: Using program evaluation data collected from September 2020 to December 2021, demographic, usage outcomes, care coordination, and support outcomes are reported. Representative case vignettes are also illustrated. RESULTS: Students (N = 258) were referred to the HSCT program for suicidality from partnering school districts in the large metropolitan area of Austin, Texas. Students referred were adolescents, 12 years of age and older (n = 196, 76%). Sixty-two (24%) of the students referred for suicidal ideation entered the HSCT program through urgent same-day assessment. Medication evaluations were offered for 125 (48%) of the students. The most frequently prescribed medications included antidepressants (e.g., SSRIs; n = 29, 64%). Program clinicians referred 12 (5%) students identified as high risk for suicide for hospitalization. Of the 258 total students, 212 (82%) were referred to community providers for therapy. CONCLUSIONS: By providing rapid access to crisis response with mental health specialists and care coordinators, at-risk students received timely evidence-based care and referral to mental health resources in their communities.

RESUMO
Objective To study the outcomes in terms of airway, voice and swallowing as well as the economic impact of the trauma on patients' finances and the constrained health infrastructure due to the pandemic. Materials and methods Study design Retrospective study. Setting: Tertiary care teaching hospital. Subjects and methods: A retrospective study was done of the 19 subjects who sustained acute laryngotracheal trauma during the SARS CoV-2 pandemic and was managed at our institution from January 2020 to September 2021. Results Change in voice was the most common presenting symptom and thyroid cartilage fractures were the commonest cartilage injury noted. It was found that 93% (decannulated) of the patients had good functional outcome and 90% of them required financial support to meet the medical expenses. Conclusion During the COVID 19 pandemic, it was not only, early presentation, timely detection and intervention by the treating team, but also the multidisciplinary teamwork and the support system that facilitated the recuperation and restoration of these traumatized individuals back into society with good laryngeal function.
RESUMO
BACKGROUND: Men diagnosed with localized prostate cancer face a potentially life-altering treatment decision that can be overwhelming. Enhancing patient knowledge through education can significantly reduce feelings of uncertainty while simultaneously increasing confidence in decision making. Serious games have been shown in other populations to increase health knowledge and assist with the health decision-making process. We developed an interactive serious game, Time After Time, which translates evidence-based treatment outcome data into an accessible and understandable format that men can utilize in their prostate cancer treatment decision-making process. The game specifically aims to raise men's awareness and understanding of the impact of health-related quality of life issues associated with the major treatment options and to enrich their conversations with their health care providers. OBJECTIVE: This study determined the acceptability and usability of the alpha version of Time After Time, an interactive decision aid for men diagnosed with localized prostate cancer, in order to inform future iterations of the serious game. METHODS: The study employed a mixed methods approach to assess the acceptability and usability of the Time After Time serious game using qualitative focus groups and a quantitative Likert scale survey. RESULTS: A total of 13 men who had already completed treatment for localized prostate cancer completed the survey and participated in focus group meetings. The majority of the study participants rated Time After Time as an appropriate decision tool for localized prostate cancer and verified that it meets its goals of increasing focus on side effects and generating questions for the patient's health care team. However, participants also expressed concerns about game usability and the diversity of information covered regarding treatment options and potential treatment outcomes. CONCLUSIONS: Serious games are a promising approach to health education and decision support for older men. Participants were receptive to the idea of a serious game as a decision aid in localized prostate cancer. However, usability issues are a major concern for this demographic, as is clarity and transparency of data sources.

In this article, the authors make a compelling case that all clinicians who treat youth with depressive disorders should embrace strategies to engage with school staff to best serve their patients in the classroom. Because these disorders have a high incidence in the school population (13% of US teens experienced at least 1 major depressive episode in 2016), this can affect learning, social interactions, and classroom engagement. Several approaches are highlighted for assessment of depressive symptoms, intervention and treatment in school settings, and prevention strategies, including depression education curricula and programs promoting subjective well-being, such as positive psychology and mindfulness.

INTRODUCTION: People living with HIV (PLHIV) have the right to exercise voluntary choices about their health, including their reproductive health. This commentary discusses the integral role that family planning (FP) plays in helping PLHIV, including those in serodiscordant relationships, achieve conception safely. The United States (US) President's Emergency Plan for AIDS Relief (PEPFAR) is committed to meeting the reproductive health needs of PLHIV by improving their access to voluntary FP counselling and services, including prevention of unintended pregnancy and counselling for safer conception. DISCUSSION: Inclusion of preconception care and counselling (PCC) as part of routine HIV services is critical to preventing unintended pregnancies and perinatal infections among PLHIV. PLHIV not desiring a current pregnancy should be provided with information and counselling on all available FP methods and then either given the method onsite or through a facilitated referral process. PLHIV, who desire children should be offered risk reduction counselling, support for HIV status disclosure and partner testing, information on safer conception options to reduce the risk of HIV transmission to the partner and the importance of adhering to antiretroviral treatment during pregnancy and breastfeeding to reduce the risk of vertical transmission to the infant. Integration of PCC, HIV and FP services at the same location is recommended to improve access to these services for PLHIV. Other considerations to be addressed include the social and structural context, the health system capacity to offer these services, and stigma and discrimination of providers. CONCLUSION: Evaluation of innovative service delivery models for delivering PCC services is needed, including provision in community-based settings. The US Government will continue to partner with local organizations, Ministries of Health, the private sector, civil society, multilateral and bilateral donors, and other key stakeholders to strengthen both the policy and programme environment to ensure that all PLHIV and serodiscordant couples have access to FP services, including prevention of unintended pregnancy and safer conception counselling.

The integration of health programs, including HIV and voluntary family planning, is a priority for US government foreign assistance. One critical component of family planning and HIV integration that has significant positive health outcomes is ensuring that all women living with HIV have access to both a full range of contraceptives and safe pregnancy counseling. This article outlines the US government global health strategy to meet the family planning needs of women living with HIV based on three key principles: a focus on reproductive rights through voluntarism and informed choice, quality service provision through evidence-based programming, and development of partnerships.
