Few studies have been conducted on the relationship between “outside-residing” resilience characteristics and the risk of developing drug use disorder later in life. These characteristics include responsive and caring parenting, household routines involving regular family meals and bedtime routines, social support from peers, participation in organized activities, and religious service attendance.

Mesenchymal stem cells (MSCs) are widely used in regenerative medicine. They can be isolated from different adult tissues. However, the regenerative potential of MSCs obtained from various sources and from different age donors may significantly differ.

The action potential (AP) in cardiac tissue is important for initiating and coordinating contractions in the heart. In addition, the long refractory period minimizes the potential for developing extrasystoles and arrhythmias. The AP is generated by coordinate changes in different ionic currents. In human (or canine) adult ventricular cells, the depolarization phase of the AP is mainly through the influx of Na+ and Ca2+ through specific voltage gated channels.

In many metazoan tissues, highly specialized cells are constantly lost and need to be replaced by tissue homeostasis from adult stem cells. When adult stem cells divide by mitosis their daughter cells either become new stem cells, or enter a proliferation and differentiation path. Recent studies in Drosophila males showed that germline stem cells (GSCs) can increase their mitotic activity in response to repeated mating.

Depression is one of the most common comorbidities of chronic diseases including diabetes and obstructive lung diseases (emphysema, chronic bronchitis, and asthma). Obstructive lung diseases and depression have few symptoms in common. However, they are both common in adults and associated with chronic inflammation. It is not clear if their coappearance in diabetic patients is coincidental or associated beyond that expected by chance.

Sleeve gastrectomy is the most common bariatric surgery worldwide. However, such a surgery caries risk of complications associated with morbidity and mortality. Gastric leak can occur and represents one of the most severe complications following sleeve gastrectomy. Since the two last decades, regenerative medicine has emerged, offering new strategies to face to sleeve gastrectomy complications.

Age-related macular degeneration (AMD) is a common and potentially devastating eye disease affecting millions of people worldwide. Among the two major subtypes of AMD, the wet form poses a significant threat to vision due to the development of choroidal neovascularization and subsequent retinal damage. Anti-vascular endothelial growth factor (anti-VEGF) therapy has revolutionized the treatment landscape for wet AMD, particularly with the advent of ranibizumab, a widely used monoclonal antibody targeting VEGF-A. The incidence of wet AMD has been steadily increasing with the ageing population, leading to a growing public health concern. Early diagnosis and prompt initiation of effective treatment are critical to preserving vision and preventing disease progression. The introduction of anti-VEGF agents, particularly ranibizumab, has significantly improved visual outcomes for many patients, leading to a reduction in severe visual loss and stabilizing or even improvement in visual acuity.

Storage and periodic elimination of urine requires coordinated activity of the bladder and the urethral outlet. This coordination is provided by a complex neural control system in the brain and spinal cord. Experimental studies in animals show that urine storage is modulated by reflex mechanisms located in the sacral spinal cord, whereas urine release is mediated by pontine micturition center in the brainstem.

Individuals with spinal cord injury (SCI) have a significantly increased risk for cognitive impairment that is associated with cerebrovascular remodeling and endothelial dysfunction. The sub-acute stage following high thoracic SCI is characterized by increased fibrosis and stiffness of cerebral arteries. However, a more prolonged duration after SCI exacerbates cerebrovascular injury by damaging endothelium.

It may seem irony that nutrition science historically pertained mostly to undernutrition and deficiency syndromes [1] but nowadays prevention, control and treatment of overnutrition, manifested as overweight and obesity, has become the main task of most nutritionists and related professionals [2]. 

This case study focuses on the clinical course of a patient who underwent decompressive surgery for an acute on chronic cervical spinal cord injury and developed white cord syndrome, a reperfusion injury, as a result of the decompression. This case study is the eighth recorded case of white cord syndrome reported globally at the time of writing this case report.

Unusual presentations of disease states that have been well characterized over the years is key to ensuring the safety of patients and decreasing the overall mortality and morbidity. Patients often present with variations on classical conditions and it is key that providers be able to recognize these variations. This case study presents a 70-year-old female with a complex past medical history with variation of the classical Hakim-Adams triad of Normal Pressure Hydrocephalus.

Adrenarche, the post-natal onset of adrenal production of DHEA (dehydroepiandrosterone) and its sulfate (DHEA-S) marks the 5-8 transition and the onset of middle childhood. However, the role of DHEA and/or DHEA-S in the cognitive, emotional and physical changes of the so-called 5-8 transition are not well-understood. 

The term “tandem spinal stenosis (TSS)” has been used to describe combined cervical and lumbar canal stenosis. We identified in our large series of cases that approximately 58% of cases with cervical canal stenosis were considered to be TSS, and 15% needed surgery for concurrent lumbar spinal canal stenosis (LCS) [1]. The simultaneous presence of thoracic canal stenosis and LCS is also frequently observed at a clinical site.

Spinal cord infarction is extremely uncommon among vascular events, accounting for only 0.3-1% of all strokes and 5-8% of acute myelopathies. While deep vein thrombosis, pulmonary embolism, and stroke are commonly observed complications of COVID-19, spinal cord infarction is relatively rare.

Anorexia nervosa (AN) is a serious psychiatric illness that carries at least a four-fold increased risk of death versus aged-matched controls. However, women with AN and concurrent depression are eight times more likely to die compared to the general population and 24 times more likely to die from unnatural causes 

Bronchopulmonary dysplasia (BPD) remains the most common disease in premature newborns, associated with immature lung injury under the influence of supplemental oxygen and mechanical ventilation. “Classical BPD” is observed in premature newborns who have not received surfactant treatments. It is characterized by pulmonary fibrosis due to oxygen toxicity and volumetric/barometric trauma caused by mechanical ventilation. A new or "mild" form of BPD is observed in children born at 29 weeks of gestation, and is characterized by disordered pulmonary development due to prematurity.

During lifespan the homeostasis and repair of organs and tissues are guaranteed by the adult stem cell population. Among them, mesenchymal stromal cells (MSCs), which contain a subpopulation of multipotent stem cells, are emerging as promising candidates for cell therapy of numerous diseases. MSCs are non-hematopoietic cells capable of self-renewal and differentiation into osteocytes, adipocytes, and chondrocytes.

Spinal dural arteriovenous fistulae (sdAVFs) are rare (5-10 per million per year), often misdiagnosed vascular lesions most commonly found in the thoracolumbar spine [1-7]. These lesions commonly present with progressive myelopathy in male (approximately 80%) patients who are usually in their 7th decade of life [3-6,8]. 

The significance of the first years of living in determining mental health later in life has been acknowledged since the early psychoanalytic approaches to the understanding of mental illness delivered by Sigmund and Anna Freud, Rene Spitz and John Bowlby. Empirical research since then has documented the early childhood origin of most mental disorders seen in older children and adolescents. Birth cohort studies have provided evidence on the interplay of genes and environment from early stages of prenatal life and the longterm influences of pre-and perinatal risk factors.
