Understanding Perceptions of Hepatitis C and Its Management Among People with Experience of Incarceration in Quebec, Canada: A Qualitative Study Guided by the Common Sense Self-Regulation Model.

Hepatitis C virus (HCV) disproportionately affects certain sub-populations, including people with experience of incarceration (PWEI). Little is known about how perceptions of HCV and treatment have changed despite simplifications in testing and treatment in carceral settings. Nineteen semi-structured interviews were conducted with people living with or having a history of HCV infection released from Quebec provincial prison.

Perceived patient navigator services and characteristics to address barriers to linkage to hepatitis C care among people released from provincial prison in Quebec, Canada.

Background: Patient navigation increases linkage to hepatitis C virus (HCV) care following release from prison; however, little is known about the services patient navigators should provide to maximize linkage to care. We aimed to identify perceived barriers and facilitators to linkage to HCV care post-release, and to determine patient navigator services and characteristics best suited to address barriers to linkage to care among people released from prison.

Methods: Ten semi-structured interviews were conducted with adult (age ≥18 years) men living with chronic HCV, released from the largest Quebec provincial prison, and linked to HCV care by a patient navigator.

Spatio-Temporal Image-Based Encoded Atlases for EEG Emotion Recognition.

Emotion recognition plays an essential role in human-human interaction since it is a key to understanding the emotional states and reactions of human beings when they are subject to events and engagements in everyday life. Moving towards human-computer interaction, the study of emotions becomes fundamental because it is at the basis of the design of advanced systems to support a broad spectrum of application areas, including forensic, rehabilitative, educational, and many others. An effective method for discriminating emotions is based on ElectroEncephaloGraphy (EEG) data analysis, which is used as input for classification systems.

A cryptozoospermic infertile male with Y chromosome AZFc microdeletion and low FSH levels due to a simultaneous polymorphism in the FSHB gene: a case report.

Genetic causes account for 10-15% of male factor infertility, making the genetic investigation an essential and useful tool, mainly in azoospermic and severely oligozoospermic men. In these patients, the most frequent findings are chromosomal abnormalities and Y chromosome long arm microdeletions, which cause a primary severe spermatogenic impairment with classically increased levels of FSH. On the other hand, polymorphisms in the FSH receptor (FSHR) and FSH beta chain (FSHB) genes have been associated with different FSH plasma levels, due to variations in the receptor sensitivity (FSHR) or in the production of FSH from the pituitary gland (FSHB).

Reimbursing incarcerated individuals for participation in research: A scoping review.

Background: Little is known about global practices regarding the provision of reimbursement for the participation of people who are incarcerated in research. To determine current practices related to the reimbursement of incarcerated populations for research, we aimed to describe international variations in practice across countries and carceral environments to help inform the development of more consistent and equitable practices.

Methods: We conducted a scoping review by searching PubMed, Cochrane library, Medline, and Embase, and conducted a grey literature search for English- and French-language articles published until September 30, 2022.

SET-PP2A complex as a new therapeutic target in KMT2A (MLL) rearranged AML.

KMT2A-rearranged (KMT2A-R) is an aggressive and chemo-refractory acute leukemia which mostly affects children. Transcriptomics-based characterization and chemical interrogation identified kinases as key drivers of survival and drug resistance in KMT2A-R leukemia. In contrast, the contribution and regulation of phosphatases is unknown.

Osteoporosis and bone metabolism in patients with Klinefelter syndrome.

Low bone mass is common in men with Klinefelter syndrome (KS), with a prevalence of 6-15% of osteoporosis and of 25-48% of osteopenia. Reduced bone mass has been described since adolescence and it might be related to both reduced bone formation and higher bone resorption. Although reduced testosterone levels are clearly involved in the pathogenesis, this relation is not always evident.

Thirty years of SET/TAF1β/I2PP2A: from the identification of the biological functions to its implications in cancer and Alzheimer's disease.

The gene encoding for the protein SE translocation (SET) was identified for the first time 30 years ago as part of a chromosomal translocation in a patient affected by leukemia. Since then, accumulating evidence have linked overexpression of SET, aberrant SET splicing, and cellular localization to cancer progression and development of neurodegenerative tauopathies such as Alzheimer's disease. Molecular biology tools, such as targeted genetic deletion, and pharmacological approaches based on SET antagonist peptides, have contributed to unveil the molecular functions of SET and its implications in human pathogenesis.

Space Flight-Promoted Insulin Resistance as a Possible Disruptor of Wound Healing.

During space flight, especially when prolonged, exposure to microgravity results in a number of pathophysiological changes such as bone loss, muscle atrophy, cardiovascular and metabolic changes and impaired wound healing, among others. Interestingly, chronic low-grade inflammation and insulin resistance appear to be pivotal events linking many of them. Interestingly, real and experimental microgravity is also associated to altered wound repair, a process that is becoming increasingly important in view of prolonged space flights.

Estradiol-Testosterone Imbalance Is Associated with Erectile Dysfunction in Patients with Klinefelter Syndrome.

Erectile dysfunction (ED) is a frequent sexual disorder in adult men. Klinefelter syndrome (KS) is the most common sex chromosomal disorder and a frequent cause of male hypogonadism. Psychological and cognitive aspects are quite typical in KS and have been linked to ED, while the role of testosterone (T) levels in sexual function of KS subjects has not been fully elucidated.

Technological innovation of Continuous Glucose Monitoring (CGM) as a tool for commercial aviation pilots with insulin-treated diabetes and stakeholders/regulators: A new chance to improve the directives?

Civil aviation pilots who develop insulin-treated diabetes and want to renew a Commercial Pilot License (CPL) represent a medical, social and regulatory problem. This depends on justified concerns about hypoglycemia, the most threatening event for people who carry out jobs requiring a high level of concentration and reliability. This negatively affects social and working aspects of pilots' lives, who have a high profile and a high-cost professional qualification.

A Fatal Case of Ciprofloxacin-induced Fulminant Hepatitis.

Unlabelled: Fatal hepatotoxicity associated with ciprofloxacin is extremely rare. This is the second fully investigated case of fulminant hepatotoxicity due to ciprofloxacin in a male patient previously ciprofloxacin tolerant. The patient's medical history included stable Waldenstrom's macroglobulinaemia, inguinal hernia repair, prostate cancer (radiotherapy in 2006) and idiopathic Parkinson's disease.

Sperm Count and Hypogonadism as Markers of General Male Health.

Background: Some evidence suggests that infertile men, who are at increased risk for hypogonadism, metabolic derangements, and osteoporosis, have higher long-term morbidity and mortality than controls, but data are scarce and not conclusive.

Objective: We tested whether semen quality and reproductive function could represent a marker of general male health.

Design, Setting, And Participants: A retrospective study of 5177 individuals from a prospectively collected database of 11516 males of infertile couples who had semen analysis in a tertiary university center.

Continuous Glucose Monitoring for In-Flight Measurement of Glucose Levels of Insulin-Treated Pilots.

Due to the risk of hypoglycemia-related incapacitation, diabetic pilots requiring insulin are assessed as unfit according to the International Civil Aviation Organization and most national authorities. Some authorities, such as those from Canada, the United Kingdom, and the United States, permit selected insulin-treated pilots (ITDM-pilots) to fly subject to a protocol requiring pre- and in-flight capillary glucose measurements to show safe levels (>100-<300 mg · dl). Critics of such permission question the practicability of these in-flight measurements and whether clinically desired glycemic targets can be achieved while keeping glucose levels in the safe range.

Recent Progress in Space Physiology and Aging.

Astronauts coming back from long-term space missions present with different health problems potentially affecting mission performance, involving all functional systems and organs and closely resembling those found in the elderly. This review points out the most recent advances in the literature in areas of expertise in which specific research groups were particularly creative, and as they relate to aging and to possible benefits on Earth for disabled people. The update of new findings and approaches in space research refers especially to neuro-immuno-endocrine-metabolic interactions, optic nerve edema, motion sickness and muscle-tendon-bone interplay and aims at providing the curious - and even possibly naïve young researchers - with a source of inspiration and of creative ideas for translational research.

Endocrine and psychological aspects of sexual dysfunction in Klinefelter patients.

Klinefelter syndrome is a frequent cause of hypogonadism, but despite hundreds of publications on different aspects of Klinefelter syndrome, only a few studies dealt with sexual dysfunction. In particular, testosterone is critical for various aspects of sexual response, but its role on sexuality in Klinefelter syndrome patients is debatable and no studies have evaluated the efficacy of testosterone treatment on sexual dysfunction in these subjects. Furthermore, the impact of psychological and relational aspects on sexual function of Klinefelter syndrome subjects is poorly defined.

Flavopiridol: An Old Drug With New Perspectives? Implication for Development of New Drugs.

Glioblastoma, the most common brain tumor, is characterized by high proliferation rate, invasion, angiogenesis, and chemo- and radio-resistance. One of most remarkable feature of glioblastoma is the switch toward a glycolytic energetic metabolism that leads to high glucose uptake and consumption and a strong production of lactate. Activation of several oncogene pathways like Akt, c-myc, and ras induces glycolysis and angiogenesis and acts to assure glycolysis prosecution, tumor proliferation, and resistance to therapy.
