Health-Related Quality of Life (HRQoL) in Co-Morbid Tuberculosis Relapse Patient: A Case Report from Malaysia

Purpose: To describe changes in HRQoL of pulmonary tuberculosis (PTB) patient and illustrate impact of malnutrition and Type II diabetes on relapse of PTB. Case: A Chinese male patient with complaints of productive cough, and loss of weight and appetite was registered; sputum smear confirmed that patient had PTB. Diagnosis was also supported by routine investigations. Patient had past history of PTB and Type II diabetes mellitus. For management of secondary tuberculosis, he was prescribed WHO recommended therapy. Elevated HbA1c levels and history of drop-off serum albumin concentration at the start of treatment demonstrated inappropriate glycaemic control and malnutrition over the past months. SF-36v2 was used to estimate HRQoL scores at start, after two months and at the end of TB therapy. Although patient’s perception of mental and physical health improved with progress of treatment, vitality (VT), social functioning (SF) and role emotion (RE) scores were still lower than Malaysian norms. Patient was declared ‘cured’ but state of ‘health’ as defined by WHO was not achieved. Conclusion: Relapse of PTB might be a consequence of inappropriate glycaemic control and malnutrition. This case report demonstrates the need for more comprehensive efforts at TB programs to improve HRQoL of TB patients.Keywords: Health-Related Quality of Life, Pulmonary tuberculosis, Malnutrition, Type II diabetes, SF 36v

Pleural Tuberculosis and its Treatment Outcomes

Purpose: To evaluate the incidence, treatment and clinical outcomes of tuberculosis pleuritis at a hospital in the state of Penang, Malaysia.Methods: A retrospective study was conducted in Hospital of Penang, Malaysia. Patient records were reviewed retrospectively to identify patients with confirmed diagnosis of tuberculous pleuritis from January 2006 to December 2008. Chest x-ray (CXR) and pleural biopsy were carried out on all patients. Directly observed therapy (DOT) was given to all patients. Data were analyzed using SPSS version 16.Results: Of 1548 tuberculosis cases, 80 (5.2 %) patients had tuberculous pleuritis. The mean age of the patients was 35.4 ± 12.87 years, with a male to female ratio of 3.4:1. Ethnically, a plurality (n = 30, 37.7 %) of cases among tuberculosis pleuritis patients were Chinese, followed by Malay (31.2 %). Out of the 80 patients with tuberculous pleuritis, 10 (12.5 %) also had diabetes mellitus, and 8 (10.0 %) HIV/AIDS. Fever, cough, chest pain and shortness of breathing were the most frequently reported symptoms. Treatment success rate was 1.558 times higher among TB group than pleuritis TB group (Odds ratio, 95 % CI, 1.06 – 2.59, p = 0.025).Conclusion: The incidence of TB pleuritis was gender- and race-related, with DM and HIV the most commonly reported risk factors. Treatment success rate was higher among pulmonary TB group than in those with TB pleuritis (extra pulmonary TB).Keywords: Tuberculosis, Pleuritis, HIV/AIDS, Biopsy, Pulmonary

Disparities in cataract surgery between Aboriginal and non-Aboriginal people in New South Wales, Australia

<b>Background:</b> To investigate variation in rates of cataract surgery in New South Wales (NSW), Australia by area of residence for Aboriginal and non-Aboriginal adults.<p></p> <b>Design:</b> Observational data linkage study of hospital admissions.<p></p> <b>Participants:</b> 289 646 NSW residents aged 30 years and over admitted to NSW hospitals for 444 551 cataract surgery procedures between 2001 and 2008.<p></p> <b>Methods:</b> Analysis of linked routinely collected hospital data using direct standardisation and multilevel negative binomial regression models accounting for clustering of individuals within Statistical Local Areas (SLAs).<p></p> <b>Main outcome measures:</b> Age-standardised cataract surgery rates and adjusted rate ratios (ARRs).<p></p> <b>Results:</b> Aboriginal people had lower rates of cataract procedures than non-Aboriginal people of the same age and sex, living in the same SLA (ARR 0.71, 95% CI 0.68-0.75). There was significant variation in cataract surgery rates across SLAs for both Aboriginal and non-Aboriginal people, with the disparity higher in major cities and less disadvantaged areas. Rates of surgery were lower for Aboriginal than non-Aboriginal people in most SLAs, but in a few, the rates were similar or higher for Aboriginal people.<p></p> <b>Conclusions:</b> Aboriginal people in NSW received less cataract surgery than non-Aboriginal people, despite evidence of higher cataract rates. This disparity was greatest in urban and wealthier areas. Higher rates of surgery for Aboriginal people observed in some specific locations are likely to reflect the availability of public ophthalmology services, targeted services for Aboriginal people and higher demand for surgery in these populations.<p></p&gt

INCREASED RADIORESISTANCE TO LETHAL DOSES OF GAMMA RAYS IN MICE AND RATS AFTER EXPOSURE TO MICROWAVE RADIATION EMITTED BY A GSM MOBILE PHONE SIMULATOR

The aim of this study was to investigate the effect of pre-irradiation with microwaves on the induction of radioadaptive response. In the 1st phase of the study, 110 male mice were divided into 8 groups. The animals in these groups were exposed/sham-exposed to microwave, low dose rate gamma or both for 5 days. On day six, the animals were exposed to a lethal dose (LD). In the 2nd phase, 30 male rats were divided into 2 groups of 15 animals. The 1st group received microwave exposure. The 2nd group (controls) received the same LD but there was no treatment before the LD. On day 5, all animals were whole-body irradiated with the LD. Statistically significant differences between the survival rate of the mice only exposed to lethal dose of gamma radiation before irradiation with a lethal dose of gamma radiation with those of the animals pre-exposed to either microwave (p=0.02), low dose rate gamma (p=0.001) or both of these physical adapting doses (p=0.003) were observed. Likewise, a statistically significant difference between survival rates of the rats in control and test groups was observed. Altogether, these experiments showed that exposure to microwave radiation may induce a significant survival adaptive response

Three-dimensional electrospun micropatterned cellulose acetate nanofiber surfaces with tunable wettability

This is the author accepted manuscript. The final version is available from the publisher via the DOI in this record.Three-dimensional polymer nanofibrous mats with tunable wettability have been fabricated using a single step non-conductive template assisted electrospinning process. Cellulose acetate nanofibers are electrospun over a nylon mesh, which acts as thetemplate. The as-deposited fiber mat is removed from this template to produce a free standing three-dimensional micropatterned nanofi-brous mat. By simply varying the template mesh dimensions, the fraction of the air-liquid interface can be changed which allows controlof the wetting mechanics. It is shown that the water contact angle can be varied from about 308 for a planar network to about 1408 for apatterned mat implying a complete transition from hydrophilic to hydrophobic behavior. Furthermore, upon stretching the fiber matloses its pattern irreversibly and reducing the contact angle from 1408 to 1108 with increasing stretching.Support of a DST-UKIERI grant is gratefully acknowl-edged.

Cytomegalovirus Infections among African-Americans

<p>Abstract</p> <p>Background</p> <p>Since African-Americans have twice the prevalence of cytomegalovirus (CMV) infections as age-matched Caucasians we sought to determine the ages and possible sources of infection of African-American children.</p> <p>Methods</p> <p>Subjects were 157 African-American healthy children and adolescents and their 113 household adults in Richmond VA. Families completed a questionnaire, provided saliva for antibody testing, and adolescents were interviewed regarding sexual activity.</p> <p>Results</p> <p>Regardless of age CMV seropositivity was not associated with gender, breast feeding, health insurance, sexual activity, or household income, education, or size. In the final regression model, prior CMV infection in adults was over two-fold higher than in children (chi-square = 18.8, p < 0.0001). At one year of age the CMV seropositivity rate was 11% (95%CI = 4% – 24%) and increased 1.8% each year until age 13 years. Between ages 13 and 20 years the CMV seropositivity rate remained between 22% and 33%. For adults, the CMV seropositivity rate was 84% in 21 year olds (95%CI = 69%–.92%). There was no association between CMV infections of the children and their mothers but CMV infections among siblings were associated.</p> <p>Conclusion</p> <p>We observed that African-American children had CMV seroprevalence rates by age 20 years at less than one-half of that of their adult mothers and caregivers. Sibling-to-sibling transmission was a likely source of CMV infections for the children. The next generation of African-American women may be highly susceptible to a primary CMV infection during pregnancy and may benefit from a CMV vaccine.</p

Phenolic Profile, Nutritional Composition, Functional Properties and Antioxidant Activity of Newly Grown Parthenocarpic and Normal Seeded Tomato

The aim of the study was to compare the physico-chemical parameters, sugar, vitamin C, and phenolic profiles in five genotypes of local indeterminate tunnel tomato hybrid (LITTH) (LITTH-778, LITTH-784, LITTH-786, LITTH-788 and LITTH-790) of natural parthenocarpic tomato (NPT) and normal seeded tomato (NST). Samples were collected from the experimental fields of Ayub Agricultural Research Institute, Faisalabad, Pakistan. Physical parameters (fruit shape, fruit weight, fruit length, fruit width, number of seeds per fruit, shelf life), chemical composition (moisture, ash, crude fat, crude fibre, total carbohydrate, crude protein, vitamin C), ofNPT and NST were analyzed by reported methods. The methanolic extracts of tomato pulp were prepared by shaking and extracts were assayed for antioxidant activity. Sugars contents and phenolic profile of NPT and NST were estimatedusing HPLC method.Weight and size of NPT were less and smaller than the NST. Moreover, NPT were seedless with longer shelf-life and had more phenolic and flavonoid contents than the NST.HPLC analysis revealed that chlorogenic acid, gallic acid, p-coumeric acid were major phenolics in methanol (polar solvent) extracts of NST whereas, caffeic acid, gallic acid, p-coumeric acid in NPT extract.NPT contained higher concentration of sugar contents, but lower concentration of vitamin C than NST. In 2,2-diphenyl-1-picrylhydrazyl(DPPH) free-radical-scavenging assay, NPT fruits extracts showed high scavenging activity with the 50% inhibitory concentration (IC50)value of 22.56 µg/mL than NSTfruit extracts having IC50 29.49 µg/mL. This study provided useful information for farmers and nutritionists

The impact of elbow and knee joint lesions on abnormal gait and posture of sows

<p>Abstract</p> <p>Background</p> <p>Joint lesions occur widespread in the Danish sow population and they are the most frequent cause for euthanasia. Clinically, it is generally impossible to differentiate between various types of non-inflammatory joint lesions. Consequently, it is often necessary to perform a post mortem examination in order to diagnose these lesions. A study was performed in order to examine the relation of abnormal gait and posture in sows with specific joint lesions, and thereby obtaining a clinical diagnostic tool, to be used by farmers and veterinarians for the evaluation of sows with joint problems.</p> <p>Methods</p> <p>The gait, posture and lesions in elbow- and knee joints of 60 randomly selected sows from one herd were scored clinically and pathologically. Associations between the scorings were estimated.</p> <p>Results</p> <p>The variables 'fore- and hind legs turned out' and 'stiff in front and rear' were associated with lesions in the elbow joint, and the variables 'hind legs turned out' and 'stiff in rear' were associated with lesions in the knee joint.</p> <p>Conclusion</p> <p>It was shown that specified gait and posture variables reflected certain joint lesions. However, further studies are needed to strengthen and optimize the diagnostic tool.</p

Polyphenoloxidase activity and total phenolic content as related to browning of minimally processed ‘Jonagored’ apple

Phenolic content, polyphenoloxidase (PPO) activity and browning have been reported by different authors to vary in different ways, depending on cultivar, picking maturity, storage conditions, etc. Numerous authors have attempted to correlate browning results with the phenolic content and/or enzymatic activity of apples, but data published in the literature are divergent as to which of the two factors, ie the enzyme or the substrate, plays the decisive role in the overall phenomenon of enzymatic browning. The aim of this work was to follow the PPO activity and phenolic content of minimally processed apple (cv ‘Jonagored’) during cold storage and to establish a potential relationship with enzymatic browning. Increasing storage time of minimally processed apple seemed to result in an increase in PPO activity. No changes (P > 0.05) in total phenolic content were observed during storage. Colour degradation of apple cubes, as indicated by changes in colour parameters, was found to be highly correlated with PPO activity. Browning of ‘Jonagored’ apple cubes during storage was found to be moderately correlated with PPO activity. No correlation was found between the browning index and the total phenolic content
