Effect Of Age

Tractor noise is critical occupational hazard which is the major cause of hearing impairment among Indian agricultural farm workers. The study aimed to show the effect of age and driving exposure on hearing impairment of drivers. Ninety healthy male subjects of similar age, height, and weight were selected and divided into four groups, i.e. 21–30, 31–40, 41–50, and 51–60 years. The audiometric testing was conducted of both the ears at 10 different frequencies, i.e. 0.125, 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, and 8 kHz. The hearing threshold levels of office workers at audiometric test frequencies did not exceed 25 dB(A) to cause hearing handicap. However, it exceeded 25 dB(A) for tractor drivers and was higher for higher age group tractor drivers. Whereas, it did not exceeded 25 dB(A) at the audiometric test frequencies for the office workers except at 51–60 years of age group. Also, with the increase in age group and increase of driving experience, the mean hearing threshold levels of tractor drivers increase. It was concluded that the occupational hazards of tractor driving significantly increased the hearing threshold levels and the risk is even higher for the tractor drivers with ≥15 years of driving experience. Also, the mean hearing threshold levels for tractor drivers increase with increase in driving experience.

The present study investigates the effect of hypobaric environments on absolute hearing thresholds for pure tones at octave frequencies between 250 Hz and 8 kHz. Absolute hearing thresholds were obtained for ten subjects at ambient pressure (732 mmHg) and at an altitude of 6500 feet (582 mmHg), relative to the laboratory. Subjects were decompressed in a hypobaric chamber at a rate of 500 ft./min. and were subjected to the low pressure environment for one hour before being compressed to a normobaric environment, at a rate of 300 ft./min. Absolute hearing threshold levels obtained at altitude, after the one hour exposure to the hypobaric ambient and on descent to normobaric conditions, were compared with scores obtained prior to the hypobaric exposure. In order to compare the frequency averaged threshold shifts at octave frequencies of 250 Hz, 500 Hz and 1 kHz, for the altitude and normobaric conditions, the audiometer was calibrated at ambient pressures of 732, 582 and 512 mmHg. The results of the study indicate a slight increase in sensitivity of the audiometer headphones with altitude and an insignificant difference between the mean frequency averaged threshold shifts for the pre-exposure test and the three experimental conditions (at the onset of hypobaria, after a one hour exposure to the altitude and on descent to surface).

Primary Screening

A stratified random cluster sample of 15,845 subjects was performed in two regions of Nepal to determine the prevalence and main causes of hearing impairment (the most common disability) and the prevalence of ear disease. Subjects reporting current ear pain, or ear discharge, or hearing impairment on direct questioning by a Nepali health worker (primary screening failed), had otoscopy and audiometry (using the Liverpool Field Audiometer) performed, and a questionnaire administered relating to past history. In every fifth house subjects who passed the primary screening (1,716 subjects) were examined to assess the false negative rate of screening. An estimated 16.6 per cent of the study population have hearing impairment (either ear worse than 30 dB hearing threshold level (HTL) 1.0–4.0 kHz, or 50 dB HTL 0.5 kHz), and 7.4 per cent ear drum pathology, equivalent to respectively 2.71 and 1.48 million people extrapolated to the whole of Nepal. Most hearing impairment in the school age group (55.2 per cent) is associated with otitis media or its sequelae. Probably at least 14 per cent of sensorineural deafness is preventable (7 per cent infectious disease, 3.9 per cent trauma, 0.8 per cent noise exposure, 1 per cent cretinism, and 1 per cent abnormal pregnancy or labour). Most individuals reporting current ear pathology (61 per cent) had never attended a health post, and of those receiving ear drop treatment, 84 per cent still had serious pathology. Of subjects who reported ear drop treatment at any time, 31 per cent still had serious pathology. The use of traditional remedies was prevalent.In conclusion this study shows high prevalences of hearing impairment and ear drum pathology. To reduce hearing impairment in Nepal, particularly in the school age group, a priority should be the effective treatment of otitis media.

The aim of this study was to examine the exercise intensity during the swimming, cycling, and running legs of nondraft legal, Olympic-distance triathlons in well-trained, age-group triathletes. Seventeen male triathletes completed incremental swimming, cycling, and running tests to exhaustion. Heart rate (HR) and workload corresponding to aerobic and anaerobic thresholds, maximal workloads, and maximal HR (HRmax) in each exercise mode were analyzed. HR and workload were monitored throughout the race. The intensity distributions in three HR zones for each discipline and five workload zones in cycling and running were quantified. The subjects were then assigned to a fast or slow group based on the total race time (range, 2 h 07 min–2 h 41 min). The mean percentages of HRmax in the swimming, cycling, and running legs were 89.8% ± 3.7%, 91.1% ± 4.4%, and 90.7% ± 5.1%, respectively, for all participants. The mean percentage of HRmax and intensity distributions during the swimming and cycling legs were similar between groups. In the running leg, the faster group spent relatively more time above HR at anaerobic threshold (AnT) and between workload at AnT and maximal workload. In conclusion, well-trained male triathletes performed at very high intensity throughout a nondraft legal, Olympic-distance triathlon race, and sustaining higher intensity during running might play a role in the success of these athletes.

Abstract Background Herpes zoster (HZ), or shingles, is a common neurocutaneous disease caused by the reactivation of latent varicella zoster virus that often includes rash and neuropathic pain that may last for months. Opioids and other analgesics may be prescribed. Recombinant zoster vaccine (RZV) is preferentially recommended for the prevention of HZ in adults aged 50 years and older. This study aimed to assess the impact of RZV vaccination on opioid and other analgesic prescription-related outcomes. Methods Estimates of analgesic prescription rates (opioids, benzodiazepines, and other analgesics) among HZ cases were established using Truven claims data from 2012-2018 for adults aged 50 years and older. HZ case avoidance with RZV vaccination was calculated using a previously published cost-effectiveness model. This data was included in a calculator assessing the impact of RZV vaccination on analgesic prescription-related outcomes (compared to no vaccination). Results Between 24.4% and 28.0% of HZ cases in the observed claims had at least one opioid prescription, dependent on age group (4.5%-6.5% and 8.6%-19.6% for benzodiazepines and other analgesics, respectively). The mean number of opioid prescriptions per person in each age group with at least one opioid prescription was between 1.7 and 1.9 (1.7-2.3 and 1.7-2.0 prescriptions for benzodiazepines and other analgesics, respectively). Assuming a 1-million-person population and 65% RZV coverage, the calculator predicts RZV vaccination will prevent 75,002 cases of HZ and will prevent 19,311 people from being prescribed at least 1 HZ-related opioid, 4,502 people from being prescribed benzodiazepines, and 12,201 people from being prescribed other analgesics. Additionally, 34,520 HZ-related opioid prescriptions will be avoided (9,413 benzodiazepine prescriptions; 22,406 other analgesic prescriptions). Conclusion HZ is associated with high levels of opioid, benzodiazepine, and other analgesic use. Primary prevention of HZ by vaccination could potentially reduce opioid and other medication exposure.

Loneliness has always been associated and reported as a risk factor of malnutrition in the elderly. People over 80 who live alone have deserved this study to detect their situation and potential for action to improve their quality of life. Objectives: To determinate the nutritional status of people over 80 living alone in the area of “La Laguna”, Cádiz. Material and method: In PIAMLA`80 program analyse those parameters and their possible correlations in a group of 342 elderly living alone over 80 years old. Different parameters were measured: Integral Geriatric Evaluation, Barthel, Lawton-Brody, Lobo, Gijon, specific analytical blood chemistry and MNA. Results: In a population of 984 people, were selected 342 initially, but finally the group decreases to 247 people. The mean Barthel was 80.42 points, 5.76 Lawton and Gijon from 11.3 Lobo 26.48. The MNA for the whole population was 24.25/30 detecting only a risk age group in women of 85-95. Correlation between nutrition and the biochemical test values showed positive for haemoglobin (0.19), total protein (0.26), Fe (0.32) and albumin (0.46). Conclusions: In our research we have not detected malnutrition in any age group or gender. The use of nutrition test MNA and its MINI version must be generalized as an accurate, clear, quick and easy tool to use.
