In high income countries, the majority of new and existing hepatitis C virus (HCV) infections occur among people who inject drugs (PWID). In many low and middle income countries large HCV epidemics have also emerged among PWID populations. The burden of HCV-related liver disease among PWID is increasing, but treatment uptake remains extremely low. There are a number of barriers to care which should be considered and systematically addressed, but should not exclude PWID from HCV treatment. The rapid development of interferon-free direct-acting antiviral (DAA) therapy for HCV infection has brought considerable optimism to the HCV sector, with the realistic hope that therapeutic intervention will soon provide near optimal efficacy with well-tolerated, short duration, all oral regimens. Further, it has been clearly demonstrated that HCV treatment is safe and effective across a broad range of…

Objective: Many patients with advanced illness are unrealistically optimistic about their prognosis. We test for the presence of several cognitive biases, including optimism bias, illusion of superiority, self-deception, misattribution, and optimistic update bias, that could explain unrealistically optimistic prognostic beliefs among advanced cancer patients and quantifies the extent to which hope exacerbates these biases.
Methods: A cross-sectional survey was administered to 200 advanced cancer patients with physician-estimated prognoses of one year or less. Hope was measured using the Herth Hope Index (HHI). Hypotheses were tested using linear and logistic regressions and a structural-equation model.
Results: Results are consistent with the presence of optimism bias, illusion of superiority, self-deception, and misattribution. All of these biases are amplified by higher levels of hope.…

Diagnosis of cancer is not a death sentence: Examining posttraumatic growth and its associated factors in cancer patients.
Objectives: Posttraumatic growth (PTG) is the experience of positive psychological growth as a result of struggle with highly challenging life crises. This study was conducted to investigate the degree of PTG and its associated factors, as well as to identify which positive psychological parameters most significantly associated with greater PTG among Malaysian cancer patients. Design, sample, & methods: This cross-sectional survey included 195 patients with different cancer diagnoses. Perceived spousal support, level of hope, level of optimism, and PTG were measured using various validated indexes. Findings: The total mean score for PTG Inventory-Short Form (PTGI-SF) was 39.87 (±9.09). Female gender, Islamic religious belief, and having higher level of hope and greater spousal support were associated with a higher PTGI-SF score, and the most significant predictor was the hope scale.

Acute symptoms of posttraumatic stress and dissociative experiences among female israeli civilians exposed to war: the roles of intrapersonal and interpersonal sources of resilience.
Background: The positive personality characteristics of optimism, hope, self-esteem, and perceived availability of social support are believed to play an important role in psychological adjustment to stressful life events. For example, these characteristics have been shown to be associated with fewer mood disturbances in response to a variety of stressors. However, relatively little is known about the extent to which these characteristics serve as sources of resilience among civilians during real-time exposure to war.
Objective: This "natural laboratory" study examined the role that individual differences both in intrapersonal (i.e., positive personality features of hope, optimism, and self-esteem) and in interpersonal (i.e., perceived social support from family, friends, and significant others) sources of resilience may play in the development of acute anxiety symptoms of posttraumatic …

Kwon P (2013)MEDLINE-indexed journal, not yet read by usPersonality and social psychology review : an official journal of the Society for Personality and Social Psychology, Inc92 citations Resilience in lesbian, gay, and bisexual individuals.
To promote psychological health among lesbian, gay, and bisexual (LGB) individuals, more comprehensive research on resilience factors in LGB individuals is needed. This article presents a theoretical framework based on the existing literature, with an eye toward guiding future research in this area. Social support clearly serves as a resilience factor for LGB individuals, in part through its ability to lower reactivity to prejudice. Social support is particularly effective when it specifically supports people's sexual orientation and is congruent with individuals' developmental needs. The ability to accept emotions and to process them in an insightful manner also buffers the negative impact of prejudice. In addition, hope and optimism allow LGB individuals to maintain psychological health when faced with prejudice.

Psychological well-being as part of the public health debate? Insight into dimensions, interventions, and policy.
Background: Increasing evidence suggests that psychological well-being (PWB) is associated with lower disease and mortality risk, and may be enhanced with relatively low-cost interventions. Yet, dissemination of these interventions remains limited, in part because insufficient attention has been paid to distinct PWB dimensions, which may impact physical health outcomes differently.
Methods: This essay first reviews the empirical evidence regarding differential relationships between all-cause mortality and multiple dimensions of PWB (e.g., life purpose, mastery, positive affect, life satisfaction, optimism). Then, individual-level positive psychology interventions aimed at increasing PWB and tested in randomized-controlled trials are reviewed as these allow for easy implementation and potentially broad outreach to improve population well-being, in concert with efforts targeting other esta…

Optimism, social support, and mental health outcomes in patients with advanced cancer.
Objective: Optimism and social support serve as protective factors against distress in medically ill patients. Very few studies have specifically explored the ways in which these variables interact to impact quality of life (QOL), particularly among patients with advanced cancer. The present study examined the role of optimism as a moderator of the relationship between social support and anxiety, depression, hopelessness, and QOL among patients with advanced cancer.
Methods: Participants (N = 168) completed self-report assessments of psychosocial, spiritual, and physical well-being, including social support, optimism, hopelessness, depressive and anxious symptoms, and QOL. Hierarchical multiple regression analyses were conducted to determine the extent to which social support and optimism were associated with depressive and anxious symptomatology, hopelessness and QOL, and the potential …

Do psychological variables affect early surgical recovery?
Background: Numerous studies have examined the effect of psychological variables on surgical recovery, but no definite conclusion has been reached yet. We sought to examine whether psychological factors influence early surgical recovery.
Methods: We performed a systematic search in PubMed, Scopus and PsycINFO databases to identify studies examining the association of preoperative psychological variables or interventions with objectively measured, early surgical outcomes.
Results: We identified 16 eligible studies, 15 of which reported a significant association between at least one psychological variable or intervention and an early postoperative outcome. However, most studies also reported psychological factors not influencing surgical recovery and there was significant heterogeneity across the studies. Overall, trait and state anxiety, state anger, active coping, subclinical depression,…

Do positive psychosocial factors predict disease progression in HIV-1? A review of the evidence.
Adding to a traditional stress perspective, behavioral medicine has been focusing increasingly on investigating the potential impact of positive psychosocial factors on disease course in HIV. Dispositional optimism, active coping, and spirituality show the most evidence for predicting slower disease progression, although the data are not entirely consistent. Findings for the role of social support are mixed, although indications are that it may be particularly helpful at later stages of illness. Many of the other constructs (positive affect, finding meaning, emotional expression/processing, openness, extraversion, conscientiousness, altruism, and self-efficacy) have only been examined in one or two studies; results are preliminary but suggestive of protective effects. Plausible behavioral and biological mechanisms are discussed (including health behaviors, neurohormones, and immune measu…

Advancements in clinical research and emerging therapies for triple-negative breast cancer treatment.
Triple-negative breast cancer (TNBC), defined by the lack of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor 2 (HER2) expression, is acknowledged as the most aggressive form of breast cancer (BC), comprising 15%-20% of all primary cases. Despite the prevalence of TNBC, effective and well-tolerated targeted therapies remain limited, with chemotherapy continuing to be the mainstay of treatment. However, the horizon is brightened by recent advancements in immunotherapy and antibody-drug conjugates (ADCs), which have garnered the U.S. Food and Drug Administration (FDA) approval for various stages of TNBC. Poly (ADP-ribose) polymerase inhibitors (PARPi), particularly for TNBC with BRCA mutations, present a promising avenue, albeit with the challenge of resistance that must be addressed. The success of phosphoinositide-3 kinase (PI3K) pathway inhibitors in…

What is life worth living for? A systematic review on meaning in life and meaning in work as protective factors for healthcare professionals' wellbeing.
The wellbeing of healthcare professionals is a topic of utmost importance in public health, given the close connection between healthcare professionals' mental health and their ability to provide high-quality care. A promising protective resource is the concept of "meaning in life" (MiL), defined as the extent to which people give meaning and purpose to their lives. A systematic review was conducted according to the PRISMA statement on three databases (PubMed, Scopus, Web of Science), searching for MiL and its influence on wellbeing among healthcare professionals. Only quantitative and qualitative research papers published in English-language peer-reviewed journals from 2000 to 2022 were considered eligible. Initially, 842 papers were retrieved. After the removal of duplicates, screening (title, abstract, full text) and quality check, 19 articles were included in the review. A narrative …

Resilience to Stress and Adversity: A Narrative Review of the Role of Positive Affect.
The modern conception of mental health encompasses not only mental illness but also mental wellbeing, including positive emotional states and other forms of positive experience. Accordingly, research on resilience - that is, recovery or adaptation following adversity - has recently expanded to consider the roles of positive affect in the resilience process. To review this research, we performed a keyword search of all peer-reviewed journals within the American Psychological Association's PsycInfo database, retrieving all studies of positive affect in the context of resilience. These studies measured positive affect either as the outcome of the resilience process or as a resilience resource in its own right. With positive affect as the outcome, the literature suggests that various resilience resources can promote positive affect following a stressor, especially positive personality traits…

Melatonin Use in Pediatrics: A Clinical Review on Indications, Multisystem Effects, and Toxicity.
Exogenous melatonin is typically used for sleep regulation in the context of insomnia either in healthy children or those with neurodevelopmental disabilities. It is also used for the management of circadian rhythm sleep disorders in pediatric and adolescent patients. There are also many other possible indications that we will discuss in this paper beyond the role of melatonin for sleep regulation, including its potential use for various areas of medicine such as inflammatory conditions. Since melatonin is unregulated in the United States, distributed over the counter and perceived to be natural and safe, it has become available in many forms in the last two decades. With increasing sleep disturbances and mental health problems after the COVID-19 pandemic, melatonin has become even more popular and studies have shown a dramatic increase in use as well as resulting side effects, including…

Cervical cancer: Novel treatment strategies offer renewed optimism.
Cervical cancer poses a significant global public health issue, primarily affecting women, and stands as one of the four most prevalent cancers affecting woman globally, which includes breast cancer, colorectal cancer, lung cancer and cervical cancer. Almost every instance of cervical cancer is associated with infections caused by the human papillomavirus (HPV). Prevention of this disease hinges on screening and immunization of the patients, yet disparities in cervical cancer occurrence exist between developed and developing nations. Multiple factors contribute to cervical cancer, including sexually transmitted diseases (STDs), reproductive and hormonal influences, genetics, and host-related factors. Preventive programs, lifestyle improvements, smoking cessation, and prompt precancerous lesion treatment can reduce the occurrence of cervical cancer. The persistency and recurrence of the c…

Unveiling the interplay of AMPK/SIRT1/PGC-1α axis in brain health: Promising targets against aging and NDDs.
The escalating prevalence of neurodegenerative diseases (NDDs) within an aging global population presents a pressing challenge. The multifaceted pathophysiological mechanisms underlying these disorders, including oxidative stress, mitochondrial dysfunction, and neuroinflammation, remain complex and elusive. Among these, the AMPK/SIRT1/PGC-1α pathway emerges as a pivotal network implicated in neuroprotection against these destructive processes. This review sheds light on the potential therapeutic implications of targeting this axis, specifically emphasizing the promising role of flavonoids in mitigating NDD-related complications. Expanding beyond conventional pharmacological approaches, the exploration of non-pharmacological interventions such as exercise and calorie restriction (CR), coupled with the investigation of natural compounds, offers a beacon of hope.

Management of chronic kidney disease: The current novel and forgotten therapies.
Chronic kidney disease (CKD) is a progressive and incurable condition that imposes a significant burden on an aging society. Although the exact prevalence of this disease is unknown, it is estimated to affect at least 800 million people worldwide. Patients with diabetes or hypertension are at a higher risk of developing chronic kidney damage. As the kidneys play a crucial role in vital physiological processes, damage to these organs can disrupt the balance of water and electrolytes, regulation of blood pressure, elimination of toxins, and metabolism of vitamin D. Early diagnosis is paramount to prevent potential complications. Treatment options such as dietary modifications and medications can help slow disease progression. In our narrative review, we have summarized the available therapeutic options to slow the progression of chronic kidney disease. Many new drug treatments have recentl…

"Cultural and conceptual knowledge": Reformulation and conceptual analysis of a key component of the health literacy model.
Extensive evidence of health disparities and systemic racism has prompted scholars to examine constructs that may account for differences in the burden of disease. One such construct is health literacy, which has been posited to have four components: print literacy, oral literacy, numeracy, and cultural and conceptual knowledge. Consistent with historical trends related to culturally based constructs, the latter component has garnered the least attention in the published literature, despite its pervasive influence on health care outcomes. We engage in a reformulation and conceptual analysis of cultural and conceptual knowledge, defined as the filter through which individuals obtain, process, and understand health information and options for diagnosis and treatment. We propose the construct of cultural schema, and operationalize the construct as having cognitive (knowledge, beliefs) and a…

Recent and future advances in intracerebral hemorrhage.
Spontaneous intracerebral hemorrhage (ICH) is defined by the rupture of a cerebral blood vessel and the entry of blood into the brain parenchyma. With a global incidence of around 3.5 million, ICH accounts for almost 30 % of all new strokes worldwide. It is also the deadliest form of acute stroke and survivors are at risk of poor functional outcome. The pathophysiology of ICH is a dynamic process with key stages occurring at successive times: vessel rupture and initial bleeding; hematoma expansion, mechanical mass effect and secondary brain injury (peri-hematomal edema). While deep perforating vasculopathy and cerebral amyloid angiopathy are responsible for 80 % of ICH, a prompt diagnostic work-up, including advanced imaging is require to exclude a treatable cause. ICH is a neurological emergency and simple therapeutic measures such as blood pressure lowering and anticoagulant reversal s…

The path to next-generation disease-modifying immunomodulatory combination therapies in Alzheimer's disease.
The cautious optimism following recent anti-amyloid therapeutic trials for Alzheimer's disease (AD) provides a glimmer of hope after years of disappointment. Although these encouraging results represent discernible progress, they also highlight the need to enhance further the still modest clinical efficacy of current disease-modifying immunotherapies. Here, we highlight crucial milestones essential for advancing precision medicine in AD. These include reevaluating the choice of therapeutic targets by considering the key role of both central neuroinflammation and peripheral immunity in disease pathogenesis, refining patient stratification by further defining the inflammatory component within the forthcoming ATN(I) (amyloid, tau and neurodegeneration (and inflammation)) classification of AD biomarkers and defining more accurate clinical outcomes and prognostic biomarkers that better reflec…

An exploration of loneliness experienced by people living with mental illness and the impact on their recovery journey: An integrative review.
WHAT IS KNOWN ON THE SUBJECT?: There is evidence that social isolation and loneliness is more prevalent in people living with mental illness than in the general population. People living with mental illness frequently experience stigma, discrimination, rejection, repeated psychiatric admissions, low self-esteem, low self-efficacy, and increased symptoms of paranoia, depression, and anxiety. There is evidence of common interventions that can be used to improve loneliness and social isolation such as psychosocial skills training and cognitive group therapy. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: This paper offers a comprehensive assessment of the evidence between mental illness, loneliness, and recovery. The results suggest that people living with mental illness experience elevated levels of social isolation and loneliness leading to poor recovery and quality of life. Social deprivati…

Mechanisms underlying HIV-associated cognitive impairment and emerging therapies for its management.
People living with HIV are affected by the chronic consequences of neurocognitive impairment (NCI) despite antiretroviral therapies that suppress viral replication, improve health and extend life. Furthermore, viral suppression does not eliminate the virus, and remaining infected cells may continue to produce viral proteins that trigger neurodegeneration. Comorbidities such as diabetes mellitus are likely to contribute substantially to CNS injury in people living with HIV, and some components of antiretroviral therapy exert undesirable side effects on the nervous system. No treatment for HIV-associated NCI has been approved by the European Medicines Agency or the US Food and Drug Administration. Historically, roadblocks to developing effective treatments have included a limited understanding of the pathophysiology of HIV-associated NCI and heterogeneity in its clinical manifestations. Th…
