Random intercept generalized linear models were used to analyze change by regressing outcomes on a contrast representing time and a correction for selectivity biases. Male and female patients had similar, overall pre-treatment characteristics including low levels of education, though education levels were lower for women. At follow-up, there were significant differences between male and female patients' self-reports of substance use and related consequences, including criminal behavior. These findings represent mixed results; while some progress has been made in offsetting gender disparities in Afghanistan, remaining significant gender differences in posttreatment results suggest more positive outcomes for female than for male patients.Evaluations of policies and programs often use a theory of change to articulate how the intervention is intended to function and the mechanisms by which it is supposed to generate outcomes. When an evaluation includes cost and efficiency considerations, economic and other concepts can be added to a theory of change to articulate a theory of value creation that articulates the mechanisms by which the intervention should use resources efficiently, effectively and create sufficient value to justify the resource use. This paper introduces some theories of value creation that are often implicit in program designs. Making these theories explicit can support clearer evaluative thinking about value for money - including specification of criteria and standards that are aligned with the theory, methods of inquiry that test the theory, and well-reasoned judgements that answer evaluative questions about value for money. Implications for evaluation practice will be discussed.Hematopoietic stem cell transplantation (HSCT) is a curative option for various hematologic malignancies. However, fatal complications, such as relapse and graft-versus-host disease (GVHD) hampered favorable HSCT outcomes. Cancer cells remained in the body following the conditioning regimen, or those contaminating the autologous graft can cause relapse. Although the relapse is much lesser in allogeneic HSCT, GVHD is still a life-threatening complication in this type of HSCT. Veliparib Researchers are seeking various strategies to reduce relapse and GVHD in HSCT with minimum effects on the engraftment and immune-reconstitution. Oncolytic viruses (OVs) are emerging anti-cancer agents with promising results in battling solid tumors. OVs can selectively replicate in the malignant cells in which the antiviral immune responses have defected. Hence, they could be used as a purging agent to eradicate the tumoral contamination of autologous grafts with no damages to hematopoietic stem cells. Moreover, they have been shown to alleviate GVHD complications through modulating alloreactive T cell responses. Primary results promise using OVs as a strategy to reduce both relapse and GVHD in the HSCT without affecting hematologic and immunologic engraftment. Herein, we provide the latest findings in the field of OV therapy in HSCT and discuss their pros and cons.Mandatory childhood vaccination is becoming an increasingly important policy intervention for governments trying to address low vaccination rates. Mandates require vaccination for a certain purpose, most commonly related to school entry for children. However, the discussion surrounding the extent and impact of mandatory vaccination programmes for babies and children have largely been limited to high-income countries. While many recent publications discuss the issue, they have not been inclusive of low- and middle-income countries. This paper thus presents a comprehensive and updatable database of mandatory childhood vaccination policies worldwide, covering 149 countries. The list indicates whether a country has a mandatory vaccination policy and the strictness of the mandate on a scale ranging across three levels of mandatory, mandatory for school entry or recommended. It draws on extensive desk-based research analysing a variety of sources, supplemented by consultations with experts from various health authorities. The paper provides an overview of the state of mandatory childhood vaccination across different World Health Organization (WHO) regions and with country case studies, setting out the general trends and issues, and engages with a discussion about why, how, and where mandatory vaccination is put in place. Our findings show in-country variation in vaccination policy and a variation between vaccination in policy compared to in practice. We observe, particularly for high-income countries, that the occurrence of recent outbreaks is a major factor for the introduction of mandatory vaccination. Also, many low- and middle- income countries have resorted to mandatory vaccination policies because of a lack of other policy options yet still have lower than targeted vaccination rates due to problems with vaccine supply, delivery, and access. Offering comparisons between countries will provide a useful tool for government decision-makers considering the merits of mandatory vaccination.Phase 3 randomized-controlled trials have provided promising results of COVID-19 vaccine efficacy, ranging from 50 to 95% against symptomatic disease as the primary endpoints, resulting in emergency use authorization/listing for several vaccines. However, given the short duration of follow-up during the clinical trials, strict eligibility criteria, emerging variants of concern, and the changing epidemiology of the pandemic, many questions still remain unanswered regarding vaccine performance. Post-introduction vaccine effectiveness evaluations can help us to understand the vaccine's effect on reducing infection and disease when used in real-world conditions. They can also address important questions that were either not studied or were incompletely studied in the trials and that will inform evolving vaccine policy, including assessment of the duration of effectiveness; effectiveness in key subpopulations, such as the very old or immunocompromised; against severe disease and death due to COVID-19; against emerging SARS-CoV-2 variants of concern; and with different vaccination schedules, such as number of doses and varying dosing intervals. WHO convened an expert panel to develop interim best practice guidance for COVID-19 vaccine effectiveness evaluations. We present a summary of the interim guidance, including discussion of different study designs, priority outcomes to evaluate, potential biases, existing surveillance platforms that can be used, and recommendations for reporting results.
