Multipronged effects of increased screen time on the nutritional imbalance: A cross-sectional study of students of Amritsar aged 6-16 years.

Background: Intense marketing of fast-food items impacts the eating habits among children and adolescents. Various studies suggest that increased screen time leads to increased fast-food consumption and decreased sleep duration, both of which are linked to obesity in growing age. Objectives: To assess screen time and dietary habits among the study group and to estimate their effect on sleep deprivation and obesity. Methods: This cross-sectional study was conducted from January 2019 to December 2019 in three schools in Amritsar selected by lottery method of simple random sampling. Out of 4,226 students, 355 overweight and obese students were interviewed regarding their dietary habits. An informed written assent was taken from the mothers. The information was collected on a semi-structured, pre-designed questionnaire by interviewing the mothers of students between 6 and 11 years of age and the students of 12-16 years. Results: 94.4% of students preferred fast foods to regular meals and 58.3% were in the habit of skipping breakfast. 59.4% had a history of daily intake of fast foods while 76.1% had a habit of consuming fast foods while watching television. Only 31.7% had an adequate sleeping pattern of 9-11 hours and 79.7% of the students had a screen time of over 3 hours. Conclusions: More the screen time, the more the chances of missing meals. Being awake for a long odd time leads to increased consumption of foods/snacks furthermore. Regarding the harmful effects of fast foods, the source of information was from schools, but only 41.4% were aware about these effects.

Real world experience with minimally invasive wireless percutaneous neuromodulation in a tertiary care centre.

Background: Wireless percutaneous nerve stimulation (PNS) for chronic pain is rapidly evolving in the ever expanding neuromodulation paradigm. Safety and lower risks with a potential of long-term analgesia cannot be over emphasised especially with the ongoing opioid pandemic. PNS with an implanted pulse generator (IPG) has also been shown to provide good benefit, without often unpleasant widespread paraesthesia from conventional spinal cord stimulators. Aim and Methods: We retrospectively extracted data on all wireless PNS implants in our highly specialised pain neuromodulation centre since initiation of wireless PNS service in August 2019. Patient demographics, pain history, analgesic intake and details on implant follow-up data within 1 year post-implant including pain relief, EuroQol-5 Dimension (EQ-5D) and Patients' Global Impression of Change (PGIC) scores were extracted. The cases are presented in a narrative format. Result: A total of five patients were implanted with wireless (Stimwave®) PNS from August 2019 to February 2020. Neuropathic pain was the most common presenting diagnosis. All patients showed >50% pain relief at 3 months. EQ-5D and PGIC did not show any improvement in the subjects. Two of the patients managed to decrease their analgesics after implantation. Similar sustained benefits could not be demonstrated after 1 year. Discussion: PNS can provide analgesia in appropriately selected cases. Naivety of the technique and procedure might cause some degree of uncertainty. External pulse generator with wireless transmission avoids IPG and tunnelling related side effects, but requires individualised special wearable technology to power the lead. Minimally invasive nature of the technique might be attractive and preferable for patients with complex medical issues, nickel allergy and poor general health who may otherwise be unsuitable for Spinal Cord Stimulation (SCS) with conventional hardware. Robust prospective controlled studies and RCTs in future might provide further insights on utility in other neuropathic pain diagnosis, long-term outcomes and acceptability compared to conventional SCS.

Spinal signalling of C-fiber mediated pleasant touch in humans.

C-tactile afferents form a distinct channel that encodes pleasant tactile stimulation. Prevailing views indicate they project, as with other unmyelinated afferents, in lamina I-spinothalamic pathways. However, we found that spinothalamic ablation in humans, whilst profoundly impairing pain, temperature and itch, had no effect on pleasant touch perception. Only discriminative touch deficits were seen. These findings preclude privileged C-tactile-lamina I-spinothalamic projections and imply integrated hedonic and discriminative spinal processing from the body.

Cordotomy in mesothelioma-related pain: a systematic review.

BACKGROUND: Cordotomy can be effective in relieving pain for patients with mesothelioma, but the evidence to support continued provision is limited. This review forms part of the Invasive Neurodestructive Procedures in Cancer Pain pilot study: The role of cordotomy in mesothelioma-related pain in the UK. AIM/DESIGN: We report on the results of the first comprehensive systematic review of the use of cordotomy in mesothelioma-related pain, with specific reference to effectiveness in relieving pain and safety. The review was conducted according to guidelines reported in the NHS Centre for Reviews and Dissemination and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for systematic reviews and meta-analyses. DATA SOURCES: 14 databases from inception to March 2012 were searched, with no limitations on language or publication type. RESULTS: Nine studies met the inclusion criteria, all of which were case series of percutaneous cervical cordotomy (PCC) involving 160 patients. All studies demonstrated good pain relief in the majority of patients. Initial post-procedure measurements showed the greatest reduction in pain. Some side effects (headache, mirror pain, motor weakness) occurred relatively frequently but were mostly transient. Respiratory dysfunction post-PCC was rare. No deaths were directly ascribed to cordotomy. CONCLUSIONS: The available evidence is significantly limited in quantity and quality. Although it seems to suggest that cordotomy might be safe and effective in this setting, more reliable evidence is needed to aid decision making on continued provision. A national registry for cordotomy would be a valuable first step in this process.

Changes in nutrient components during ageing of emerging juvenile bamboo shoots.

The newly emerging, tender juvenile shoots of bamboos that belong to the tribe Bambuseae, subfamily Bambusoideae of family Poaceae, are edible. Their rich content of amino acids, proteins, carbohydrates, vitamins, minerals and low fat content attracts many people to consume bamboo shoots. A study was conducted to determine the nutrient changes in emerging juvenile shoots of five commercially important bamboos. It was observed that whereas nutrient components of the shoots depleted in all the five species with ageing, the dietary fibre and moisture content were increased. Vitamins and mineral content also decreased in the older shoots. The present study indicates that the freshly emerging juvenile shoots are nutritionally superior to the older emerged shoots.

Influence of chronic phenytoin administration on the pharmacokinetics and pharmacodynamics of vecuronium.

BACKGROUND: The duration of action of vecuronium is reduced in patients receiving phenytoin. In this study, the authors examined, simultaneously, the influence of phenytoin on both the pharmacokinetics and the pharmacodynamics of vecuronium. METHODS: This study was approved by the institutional review board of the University of California, San Francisco, and patients gave written informed consent. Twenty-two patients, 11 taking phenytoin and all scheduled to undergo prolonged neurosurgical procedures with general anesthesia, participated in the study. In 12 patients (6 phenytoin, 6 control), vecuronium was infused at 7.5 microg x kg(-1) x min(-1) until the first response (T1) of each train-of-four decreased by 50%; in the remaining 10 patients (5 phenytoin, 5 control), 200 microg/kg vecuronium was infused over 10 min. Arterial blood samples were drawn at intervals over the next 5-7 h. Plasma concentrations of vecuronium and 3-desacetylvecuronium were measured by capillary gas chromatography. Pharmacokinetic and pharmacodynamic modeling was used to characterize the disposition of vecuronium and patient responses to it in the two groups. RESULTS: Clearance was typically increased by 138% (95% confidence interval, 93-183%) in patients taking phenytoin. The effect of vecuronium was well described using a sigmoid Emax model. The concentration of vecuronium giving 50% twitch depression was increased 124% (45-202%) in patients taking phenytoin. CONCLUSIONS: Chronic phenytoin therapy reduces the effect of vecuronium by mechanisms that include both increased vecuronium metabolism and reduced sensitivity of the patient to circulating concentrations of vecuronium.

The influence of mild hypothermia on the pharmacokinetics and time course of action of neostigmine in anesthetized volunteers.

BACKGROUND: The pharmacokinetics, maximum effect, and time course of action of neostigmine were studied in seven human volunteers. METHODS: Each volunteer was studied twice, during both normothermia and hypothermia. Anesthesia was induced with 30 microg/kg alfentanil and 3 mg/kg propofol, and was maintained with 60-70% nitrous oxide and 0.7-0.9% isoflurane. The mechanical response of the adductor pollicis to train-of-four stimulation of the ulnar nerve was recorded, and central body temperature maintained stable at either less than 34.5 degrees C or greater than 36.5 degrees C by surface cooling or warming. Before neostigmine administration, a stable 5% twitch height was obtained by an infusion of vecuronium, and the infusion rate remained unchanged thereafter. Neostigmine, 70 microg/kg, was then infused over 2 min, and blood samples for estimation of neostigmine concentrations were collected at intervals for 240 min. RESULTS: With hypothermia, the central volume of distribution of neostigmine decreased by 38%, and onset time of maximum effect increased (4.6 vs. 5.6 min). Hypothermia did not change the clearance (696 ml/min), maximum effect, or duration of action of neostigmine. CONCLUSIONS: The efficacy of neostigmine as an antagonist of vecuronium-induced neuromuscular block is not altered by mild hypothermia.
