Fall reduction

Individuals must reproduce to survive and thrive from generation to generation. In fish, the fecundity of individuals and estimates of total reproductive output are critical for evaluating reproductive success and understanding population dynamics. Estimating fecundity is an onerous task; therefore, many populations lack contemporary estimates of fecundity and size-fecundity relationships. However, reproductive dynamics are not static in time; therefore, it is important to develop contemporary fecundity estimates to better inform conservation and management action...

BACKGROUND/OBJECTIVE: Falls research in older adults with MS (OAMS) is scarce, and no studies have reported on the association between life-space mobility and falls in this group. Herein, we hypothesized that higher baseline life-space scores would be associated with reduced odds of reporting falls during follow-up, and explored whether the association differed by MS subtype (progressive vs. relapsing-remitting). METHODS: OAMS (n = 91, mean age = 64.7 ± 4.3ys, %female = 66...

An intense period of human population expansion over the past 250 years is about to cease. Total fertility rates are falling dramatically all over the world such that highly industrialized nations, including China and the tiger economies of SE Asia, will see their populations decline significantly in the coming decades. The socioeconomic, geopolitical and environmental ramifications of this change are considerable and invite a multidisciplinary consideration of the underlying mechanisms. In the short-term, socioeconomic factors, particularly urbanization and delayed childbearing are powerful drivers of reduced fertility...

PURPOSE: Physical restraint (PR) is applied for patients' safety and to prevent the removal of inserted devices. No matter how well applied, PR causes undesired effects and discomfort to patients. Because PR-Guidelines are not yet implemented in Turkey, an observational study was performed to get baseline data on the type and number of PR-activities and on patients' complications in intensive care unit (ICU) patients. METHODS: An observational pilot study was conducted in anesthesia and reanimation adult ICUs in a midsized general hospital in Turkey...

During the twentieth century, childhood mortality was dramatically reduced globally, falling by more than 90% in the United States and much of Europe. Total fertility also fell, with the combined result that many parents who otherwise would have experienced the loss of a child were spared the trauma and negative health consequences that accompany such a loss. Here I use mathematical modeling to argue that the reduction in the frequency of child death that occurred in the twentieth century indirectly led to a substantial reduction in female mortality, resulting in an extension of female lifespan...

BACKGROUND: A single administration of the opioid receptor antagonist methocinnamox (MCAM) antagonizes the antinociceptive effects of µ-opioid receptor agonists for 2 weeks or longer. Such a long duration of antagonism could necessitate the use of nonopioid drugs for treating pain in patients receiving MCAM for opioid use disorder (OUD). METHODS: The antinociceptive effects of fentanyl and nonopioid drugs were assessed in 24 male Sprague Dawley rats using a complete Freund's adjuvant (CFA) model of inflammatory pain...

BACKGROUND: Substance use continues to remain a public health issue for youths in the United States. Black youths living in urban communities are at a heightened risk of poor outcomes associated with substance use and misuse due to exposure to stressors in their neighborhoods, racial discrimination, and lack of prevention education programs specifically targeting Black youths. Many Black youths, especially those who live in urban communities, do not have access to culturally tailored interventions, leaving a critical gap in prevention...

BACKGROUND: Postural imbalance and falls are an early disabling symptom in patients with progressive supranuclear palsy (PSP) of multifactorial origin that may involve abnormal vestibulospinal reflexes. Low-intensity noisy galvanic vestibular stimulation (nGVS) is a non-invasive treatment to normalize deficient vestibular function and attenuate imbalance in Parkinson's disease. The presumed therapeutic mode of nGVS is stochastic resonance (SR), a mechanism by which weak sensory noise stimulation can enhance sensory information processing...

Transient receptor potential vanilloid 4 channel ( TRPV4 ) gene mutations have been described in skeletal system and peripheral nervous system pathology. The case described here is a 9-year-old male child patient, born to a nonconsanguineous marriage with normal birth history who had difficulty in walking and stiffness of joints for the last 7 years, and progressive weakness of all four limbs and urine incontinence for 1 year following falls. Physical examination showed below-average weight and height and short trunk...

AIM: To synthesize existing literature describing the impact of intentional rounding on patient outcomes among hospitalized adults. BACKGROUND: Intentional rounding has been described as purposeful therapeutic communication between nurses and patients during regular checks with patients using standardized protocols. Despite the widespread adoption of intentional rounding, the current understanding of the benefits of these structured interactions between nurses and patients is limited...

OBJECTIVE: To describe the successful surgical management of a previously unreported Salter-Harris type I fracture of the accessory carpal bone in a dog. ANIMAL: An 11-week-old intact female Golden Retriever-Poodle cross presented with a history of a marked left forelimb lameness following a suspected fall from a height. CLINICAL PRESENTATION, PROGRESSION, AND PROCEDURES: On physical examination, the patient demonstrated a severe left forelimb lameness and pain on palpation and range of motion of the left carpus...

Norfloxacin (NOR) is widely used in medicine and animal husbandry, but its accumulation in the environment poses a substantial threat to ecological and human health. Traditional physical, chemical, and rudimentary biological methods often fall short in mitigating NOR contamination, necessitating innovative biological approaches. This study proposes an engineered bacterial consortium found in marine sediment as a strategy to enhance NOR degradation through inter-strain co-metabolism of diverse substrates. Strategically supplementing the engineered bacterial consortium with exogenous carbon sources and metal ions boosted the activity of key degradation enzymes like laccase, manganese peroxidase, and dehydrogenase...

Hepatitis B virus (HBV) infection is a dynamic disease where patients progress through several stages defined by HBV e-antigen (HBeAg) status, HBV-DNA levels and transaminase elevations, with antiviral therapy indicated only in specific stages. However, some patients cannot be classified into one of the stages and are said to fall into an 'indeterminate phase' or 'grey zone'. Exact definitions of the indeterminate phase vary from guideline to guideline as a result of different cut-off values for biomarker measurements...

CONTEXT: A third of the population aged 65 and over experiences a fall during a given year, often with severe traumatic consequences, dependence, and consequently, a decline in quality of life. The fear of falling itself leads to avoidance behavior from daily activities leading to a downward spiral of dependence, loss of confidence, and therefore an increased risk of falling. Joint stiffness is often observed during clinical examination of elderly people. However, the association between lumbopelvic stiffness and fear of falling has not been studied...

Chitosan, sourced from abundant chitin-rich waste streams, emerges as a promising candidate in the realm of future functional materials and chemicals. While showing numerous advantageous properties, chitosan sometimes falls short of competing with today's non-renewable alternatives. Chemical derivatization, particularly through N-alkylation, proves promising in enhancing hydrophobic functionalities. This study synthesizes fifteen chitosan derivatives (degree of substitution = 2-10 %) using an improved reductive amination method...

The fall armyworm (FAW), Spodoptera frugiperda (JE Smith) (Lepidoptera: Noctuidae), an invasive agricultural pest, has significantly impacted crop yields across Africa. This study investigated the relationship between temperature and FAW life history traits, employing life cycle modeling at temperatures of 20, 25, 28, 30, and 32°C. The development time for eggs, larvae, and pupae varied from 0-3 days, 10-18 days, and 7-16 days, respectively. The optimal temperature range for immature stage survival and female fecundity was identified as 21-25°C, with the intrinsic rate of increase (rm) and gross reproductive rate (GRR) peaking at 25-28°C...

OBJECTIVES: This study aimed to systematically review and synthesize the perspectives and experiences of community-dwelling older adults who experience falling, to inform the subsequent development of fall prevention and management interventions, and to provide recommendations for healthcare policy and practice. METHODS: The review was a qualitative meta-aggregation study following the JBI qualitative systematic review methodology. Databases searched included Medline (through PubMed), CINAHL, PsycINFO, Embase, and the Web of Science...

Congenital arterial stenosis such as supravalvar aortic stenosis (SVAS) are highly prevalent in Williams syndrome (WS) and other arteriopathies pose a substantial health risk. Conventional tools for severity assessment, including clinical findings and pressure gradient estimations, often fall short due to their susceptibility to transient physiological changes and disease stage influences. Moreover, in the pediatric population, the severity of these and other congenital heart defects (CHDs) often restricts the applicability of invasive techniques for obtaining crucial physiological data...

β-Thalassemia is the world's number 1 single-gene genetic disorder and is characterized by suppressed or impaired production of β-pearl protein chains. This results in intramedullary destruction and premature lysis of red blood cells in peripheral blood. Among them, patients with transfusion-dependent β-thalassemia face the problem of long-term transfusion and iron chelation therapy, which leads to clinical complications and great economic stress. As gene editing technology improves, we are seeing the dawn of a cure for the disease, with its reduction of ineffective erythropoiesis and effective prolongation of survival in critically ill patients...

Dexterous postural control subtly complements movement variability with sensory correlations at many scales. The expressive poise of gymnasts exemplifies this lyrical punctuation of release with constraint, from coarse grain to fine scales. Dexterous postural control upon a 2D support surface might collapse the variation of center of pressure (CoP) to a relatively 1D orientation-a direction often oriented towards the focal point of a visual task. Sensory corrections in dexterous postural control might manifest in temporal correlations, specifically as fractional Brownian motions whose differences are more and less correlated with fractional Gaussian noises ( fGn s) with progressively larger and smaller Hurst exponent H ...
