Serum tumour necrosis factor alpha in osteopenic and osteoporotic postmenopausal females: A cross-sectional study in Pakistan

Objective: To compare biochemical parameters serum tumour necrosis factor alpha, calcium, magnesium, bone-specific alkaline phosphatase and vitamin D in postmenopausal women.Methods: This cross-sectional study was carried out from June 2015 to July 2016 at Jinnah Medical and Dental College, Karachi, and comprised postmenopausal women. Bone mineral density done by dual energy X-ray absorptiometryscan categorised subjects by World Health Organisation classification into normal (T score \u3e -1) osteopenic (T score between -1 and -2.5) and osteoporotic (T score \u3c -2.5). Biochemical parameters like tumour necrosis alpha, calcium, magnesium, bone-specific alkaline phosphatase and vitamin D were measured by solid phase enzyme amplified sensitivity immunoassay method. SPSS 16 was used to analyse the data.Results: Of the 146 women, 34(23%) were normal, 93(67%) were osteopenic and 19(13%) were osteoporotic. There was significant difference in mean body mass index, serum tumour necrosis factor alpha and calcium in all the three groups (p\u3c0.01). Significant mean difference was observed in serum calcium levels between normal and osteopenic, and between normal and osteoporotic group (p\u3c0.05 each) without any significant mean difference between osteopenic and osteoporotic groups (p\u3e0.05). A significant difference was observed for mean tumour necrosis factor alpha values between normal and osteoporotic groups (p\u3c0.05). Tumour necrosis factor alpha showed negative correlation with bone mineral density in osteopenic and osteoporotic groups (p\u3e0.05).Conclusions: Increased bone turnover in postmenopausal osteopenic women can be predicted by increased serum cytokine

Effects of nonpharmacological interventions on disruptive vocalisation in nursing home patients with dementia-A systematic review

Background: Vocally disruptive behaviour is a common and difficult to treat condition in older residents with dementia. The aim of this systematic review is to evaluate the efficacy of nonpharmacological interventions in its management in persons with dementia residing in a nursing home.Methodology: A systematic search was conducted using Ovid MEDLINE, CINAHL, and Cochrane databases and reference lists from relevant publications on various nonpharmacological approaches to manage vocally disruptive behaviour in nursing home residents. The method of appraisal was through the National Institutes of Health scoring for the Quality Assessment of controlled intervention studies. Inclusion criteria included residents of nursing homes over the age of 65 with dementia and disruptive vocalisation. Only randomised controlled trials published in English were included.Results: A total of 5,606 articles were identified, which cover 501 trials, of which 23 were selected. There were fourteen studies observed to have an impact of clinical and statistical significance with interventions including (i) a multidimensional approach with different nonpharmacological interventions, (ii) multisensory stimulation, (iii) staff education and training, (iv) personalised bathing, and (v) pain recognition and appropriate management. Seven studies demonstrated no observable effect whereas two showed worsening in vocally disruptive behaviour.Conclusions: Many aspects of vocally disruptive behaviour management are poorly understood. Limited empirical evidence supports the use of several nonpharmacological interventions to reduce it. There is more robust evidence to support the use of a tailored approach to management over the universal approach

Meat- and plant-based products induced similar satiation which was not affected by multimodal augmentation

Little is known about how plant-based products influence satiation compared to corresponding meat-based products. As augmented reality (AR) intensifies sensory experiences, it was hypothesized to improve satiation. This study compared satiation between intake of meatballs and plant-based balls and plant-based balls intensified with AR for visual, olfactory, and haptic sensory properties. Intake order of the meatballs, plant-based balls, and augmented plant-based balls, eaten on separate days, was randomized. Satiation was measured from twenty-eight non-obese adults as ad libitum intake of the balls and extra snacks, and as subjective appetite sensations. Liking and wanting to eat the products were also investigated.There were no differences between the products in satiation. Before tasting the augmented plant-based balls were less liked than the meatballs (p = 0.002) or plant-based balls (p = 0.046), but after eating the first ball or eating the ad libitum number of balls the differences in liking disappeared. Wanting evaluations were similar for each product and decreased during eating (p < 0.001). A group of participants susceptible to AR was found (n = 11), described by decreased intake when augmentation was applied. Among the sub-group, wanting to eat the augmented balls was lower before tasting (p = 0.019) and after eating the first ball (p = 0.002) and appetite was less suppressed after eating the balls ad libitum (p = 0.01), when compared to non-susceptible participants.We conclude that meatballs and plant-based balls were equal in inducing satiation, and multisensory augmentation did not influence satiation. However, the augmentation decreased liking evaluations before tasting. Further studies are needed to explore differences between consumer groups in susceptibility to augmentation

Minimal information for studies of extracellular vesicles 2018 (MISEV2018):a position statement of the International Society for Extracellular Vesicles and update of the MISEV2014 guidelines

The last decade has seen a sharp increase in the number of scientific publications describing physiological and pathological functions of extracellular vesicles (EVs), a collective term covering various subtypes of cell-released, membranous structures, called exosomes, microvesicles, microparticles, ectosomes, oncosomes, apoptotic bodies, and many other names. However, specific issues arise when working with these entities, whose size and amount often make them difficult to obtain as relatively pure preparations, and to characterize properly. The International Society for Extracellular Vesicles (ISEV) proposed Minimal Information for Studies of Extracellular Vesicles (“MISEV”) guidelines for the field in 2014. We now update these “MISEV2014” guidelines based on evolution of the collective knowledge in the last four years. An important point to consider is that ascribing a specific function to EVs in general, or to subtypes of EVs, requires reporting of specific information beyond mere description of function in a crude, potentially contaminated, and heterogeneous preparation. For example, claims that exosomes are endowed with exquisite and specific activities remain difficult to support experimentally, given our still limited knowledge of their specific molecular machineries of biogenesis and release, as compared with other biophysically similar EVs. The MISEV2018 guidelines include tables and outlines of suggested protocols and steps to follow to document specific EV-associated functional activities. Finally, a checklist is provided with summaries of key points

Case report and literature review of an atypical polymyalgia rheumatica and its management

Polymyalgia rheumatica (PMR) is a systemic inflammatory disease of the elderly population that increases in incidence as age advances. It is characterised by the sudden or sub-acute onset of symptoms affecting the shoulder and pelvic girdles, often accompanied by constitutional symptoms. Due to the lack of consensual diagnostic criteria and specific laboratory or radiological investigations for PMR, its diagnosis can be very challenging, particularly because it can be mimicked or masked by other geriatric syndromes. PMR responds well to glucocorticoid treatment, but if left untreated, can lead to morbidity and poor quality of life. We present the case of an 87-year-old male who presented with a one-week history of localised pain in the left hip joint, later involving the contralateral hip. Previously able to ambulate unaided, his mobility was now severely impaired. Due to his Alzheimer\u27s dementia and multiple comorbid geriatric conditions, extensive investigations were undertaken before a diagnosis of atypical PMR was reached. Treatment with a low dose of prednisolone led to a full recovery. This case highlights the inconsistency between an atypical presentation and the classic presentation of PMR and draws attention to the possibility of missed diagnosis in older, frail patients. Atypical symptomatology on top of cognitive impairment and language barriers can be easily overlooked and left untreated and could lead to severe adverse outcomes. Accurate diagnosis is crucial, as PMR is readily diagnosed, but the treatment with glucocorticoids, though generally straightforward, can pose challenges, particularly when dealing with polypharmacy and multiple coexisting health conditions

Daily consumption of commercial chicken feed and meat lead to alterations in serum cholesterol and steroidal sex hormones in female rats

Poultry consumption is increased worldwide owing to better taste, easy availability and low cost. The present study was designed to investigate the effects of the chicken feed, conventional chicken meat and organic chicken meat on the % growth rate, serum cholesterol, progesterone, testosterone and estrogen levels in female rats. Hundred female Albino Wistar rats were randomly assigned to four groups (n=25). Group I was control rats fed on standard chow, group II treated with commercial chicken feed, group III rats fed with conventional chicken meat and group IV with organic chicken meat for a period of 6 weeks. % Growth rate, serum cholesterol, progesterone, testosterone and estrogen levels were estimated after the treatment. The present study showed significant increase in growth rate, serum cholesterol levels and imbalance in serum steroidal hormone levels. It is therefore, suggested from the present study that the intake of commercial chicken feed and commercial chicken meat may be the potential cause of development of polycystic ovary syndrome in females due to steroid hormonal imbalance

Effects of feed additives on chicken growth and their residues in meat instigating deleterious consequences on the liver health of consumers - A prospective human study

The liver is a multifunctional organ that metabolizes all forms of diets, and food ingredients can have beneficial or detrimental effects on liver cells during such a process. As we have already studied the components of chicken feed previously, the purpose of this study was to observe the effects of chicken meat consumption on liver cells of rats. One hundred and twenty female Albino Wistar rats were randomly divided into four groups and separately for standard chow rat, commercial chicken feed, commercial chicken meat and organic chicken meat over a six-week period. Plasma levels of tumor necrosis factor alpha (TNF-α) and alpha-fetoprotein (AFP) were estimated before and after the administration of different meals. After the experiment, the liver samples were weighed and histopathologically evaluated using a knodell score to assess portal hypertension and liver damage. Animals fed with commercial chicken meat and feed for six weeks showed development of inflammation, necrosis, apoptosis and cirrhosis on histopathological examination of the liver, and had raised plasma TNF-α and AFP-levels. This study shows that damage to liver cells is caused by consumption of commercial feed for chickens and their meat which is considered safe for human consumption

Natural remedies for Alzheimer\u27s disease: A systematic review of randomized controlled trials

Alzheimer\u27s disease (AD) is the common type of dementia and is currently incurable. Existing FDA-approved AD drugs may not be effective for everyone, they cannot cure the disease nor stop its progression and their effects diminish over time. Therefore, the present review aimed to explore the role of natural alternatives in the treatment of AD. A systematic search was conducted using Ovid MEDLINE, CINAHL, Cochrane and PubMed databases and reference lists up to November 30, 2021. Only randomized control trials were included and appraised using the National Institute of Health framework. Data analysis showed that herbs like Gingko Biloba, Melissa Officinalis, Salvia officinalis, Ginseng and saffron alone or in combination with curcumin, low-fat diet, NuAD-Trail, and soy lecithin showed significant positive effects on AD. Moreover, combination of natural and pharmaceuticals has far better effects than only allopathic treatment. Thus, different herbal remedies in combination with FDA approved drugs are effective and more promising in treatment of AD
