Unbearable weight: young adult women's experiences of being overweight

Being overweight is a hazard to health. Overweight people have a very negative image due to the marketing strategies for weight reduction and beauty products. Young women establishing self-image, seeking affirmation of social peers, and looking for potential mates are usually concerned about their weight and figure. To investigate the experience of young women who think they are overweight, how they come to think in this way, and the impact of this thinking, this qualitative pilot study conducted semi-structured interviews with five participants. On the basis of the qualitative method, data was subjected to constant comparison and content analysis. The phenomenon can thus be described in three major categories: (1) Social labeling of the overweight - a slim image is overwhelmingly preferred; (2) Pursuing attractiveness or health - a self-struggling process; (3) Weight reduction and self control - an endless struggle. The result of the study suggests there is a need for a competitive image to counter current obsessions with painfully slender figures in society. To protect the public's mental and physical health, nurses should play an active role in weight education based on a deeper and more dynamic understanding of being overweight.     

Association analysis of a neural nitric oxide synthase gene polymorphism and antipsychotics-induced tardive dyskinesia in Chinese schizophrenic patients

Summary. Recent findings from rodent studies with chronic administration of antipsychotic drugs have indicated the role of neural nitric oxide synthase (NOS1) on the susceptibility of tardive dyskinesia (TD). In the present study, the association between a 3-untranslated region C267T (3-UTR C267T) polymorphism of the NOS1 gene and TD as well as TD severity was investigated in 251 Chinese schizophrenic patients with long-term antipsychotic treatment (TD: 128, non-TD: 123). After adjusting the effects of confounding factors, there was no significant association between NOS1 3-UTR C276T genotypes and TD occurrence (p=0.758). With in the TD group, we could not discover a significant correlation between NOS1 3-UTR C276T genotypes and the scores of abnormal involuntary movement scale (AIMS) (p=0.219 and 0.774). We concluded that the NOS1 3-UTR C276T polymorphism might not play a major role in the susceptibility of TD development, or on the severity of TD.     

Influenza and pneumococcal vaccination of the elderly in Taiwan

In 1998, Taiwan became the first country in Asia to provide free influenza vaccination to high-risk groups, mainly the elderly. The purpose of this study is to determine: (1) the annual mortality rate from influenza and pneumococcal-related illnesses such as pneumonia, chronic bronchitis, pulmonary emphysema and asthma and (2) the effectiveness of and adverse events associated with the influenza vaccination. In the elderly, influenza vaccination caused the annual death rate due chronic bronchitis, pulmonary emphysema, and asthma to decline steadily but had no effect on the annual pneumonia death rate. The only adverse effect of concern was vertigo (in approximately 2-3%).     

Meta-analysis of standard mortality ratio in cotton textile workers

Background: Pulmonary function tests may reveal obstructive lung disease with altered forced expiratory volume in 1 s (FEV₁) in cotton textile workers. Since 1930, many cohort studies have been performed to assess the disease mortality rate in cotton textile workers. Materials and methods: The authors performed a meta-analysis of the SMR results of these studies. Results: From the meta-analysis, the SMRs were as follows: for all deaths, 0.792 in males and 0.873 in females; for cancers, 0.705 in males and 0.829 in females. Discussion: The male cotton textile workers were healthier than the general population. The healthy-worker effect may be one of the causes, in general workers in industry have a better mortality patterns than those not working.     

No association between the neuronal nitric oxide synthase gene polymorphism and Alzheimer Disease

Nitric oxide synthase (NOS) has been implicated in the pathogenesis of Alzheimer disease (AD). To examine the role of the neuronal NOS (nNOS) gene in AD, patients (n = 139) and control subjects (n = 101) were genotyped for the nNOS dinucleotide polymorphism. No association was demonstrated for AD and this particular nNOS polymorphism.     

Chemical burn caused by povidone-iodine alcohol solution--a case report

Burns associated with chemical disinfectants for skin preparation are rare. Skin irritation and maceration associated with pressure factors may contribute to its occurrence. We report a 24-year-old female with thyroid tumor who was admitted for subtotal thyroidectomy. After anesthetic induction, the patient was placed in the supine position with the trunk elevated to 20 degree. The skin over the anterior neck was sterilized with 10% Povidone-iodine (PI) alcohol solution. After a 3-hour surgery, the patient complained of burning pain over the back at the recovery room. Physical examination revealed a 9 x 11 cm area of skin lesion partially thickened amid on the middle of the back suggestive of chemical burn. After conservative treatment, she was discharged uneventfully 4 days later. Upon follow-up, the wound was seen to heal with minimal scarring within 3 weeks.     

Comparison of subjective visual acuity with visual acuity predicted from C-scan topography

PURPOSE: To compare the capability of objective measures of visual acuity (potential visual acuity from C-scan) to predict subjective visual acuity (best spectacle-corrected visual acuity [BSCVA]). METHODS: Patients with BSCVA > or = 20/20 were enrolled in four groups (Group 1: normal [33 eyes]; Group 2: < -7.00 D myopia [43 eyes]; Group 3: > or = -7.00 D myopia [28 eyes]; Group 4: At least 1 month after LASIK [93 eyes]). Videokeratography was performed with the ray tracing Technomed C-scan. The potential visual acuity from C-scan was obtained with pupils undilated and intact precorneal tear films. All visual acuity was recorded in logMAR, and the significance of differences between acuities was assessed with a one-way ANOVA test. RESULTS: The potential visual acuity from C-scan ray tracing of normal and myopic eyes in response to both photopic and mesopic stimuli did not differ. In a given eye, the potential visual acuity from C-scan ray tracing was better than BSCVA, and the difference was statistically significant. Although the potential visual acuity from C-scan of postoperative LASIK eyes in response to photopic stimuli was the same, it decreased under mesopic conditions. CONCLUSIONS: Potential visual acuity from C-scan overestimates subjective visual acuity due to the inadequate assumptions in ray tracing or individual retinal resolution ability. In addition, the potential visual acuity from C-scan ray tracing varies with pupil diameter in different illumination.     

Pretreatment with small-dose ketamine reduces withdrawal movements associated with injection of rocuronium in pediatric patients

We evaluated the pretreatment of small-dose of ketamine or normal saline in the reduction of withdrawal movements induced by rocuronium injection. One-hundred pediatric patients (aged 1-6 yr) were randomly assigned into 2 groups. A 22-gauge IV cannula was inserted into the dorsum of the hand, and ketamine 0.2 mg/kg or normal saline was given, followed by a 5 mg/kg thiopental injection 10 s later. IV rocuronium (0.8 mg/kg) was injected over 5 s. The patient's response to rocuronium injection was graded by using a four-point scale in a double-blinded manner. We observed that the incidence of withdrawal movements was 83% in the saline group and 27% in patients pretreated with ketamine (P < 0.05). Some patients in both groups developed skin erythema at the site of injection. We conclude that pretreatment with small-dose ketamine significantly attenuates withdrawal movements associated with IV injection of rocuronium in pediatric patients anesthetized with thiopental. IMPLICATIONS: Pretreatment with small-dose ketamine 0.2 mg/kg provides a simple and safe means of reducing the incidence of withdrawal movements induced by the injection of rocuronium, a short-acting nondepolarizing muscle relaxant.
