RESUMO
BACKGROUND: Quality of Life-Aged Care Consumers (QOL-ACC) is a new older-person-specific quality of life instrument designed for application in quality assessment and economic evaluation in aged care. The QOL-ACC was designed from its inception with older people receiving aged care services ensuring its strong content validity. Given that the QOL-ACC has already been validated in home care settings and a preference-weighted value set developed, we aimed to assess feasibility, construct validity and reliability of the QOL-ACC in residential aged care settings. METHODS: Individuals living in residential aged care facilities participated in an interviewer-facilitated survey. The survey included the QOL-ACC, QCE-ACC (quality of aged care experience measure) and two other preference-based quality of life instruments (ASCOT and EQ-5D-5L). Feasibility was assessed using missing data and ceiling/floor effects. Construct validity was assessed by exploring the relationship between the QOL-ACC and other instruments (convergent validity) and the QOL-ACC's ability to discriminate varying levels of self-rated health and quality of life. Internal consistency reliability was assessed using Cronbach's alpha (α). RESULTS: Of the 200 residents (mean age, 85 ± 7.7 years) who completed the survey, 60% were female and 69% were born in Australia. One in three participating residents self-rated their health as fair/poor. The QOL-ACC had no missing data but had small floor effects (0.5%) and acceptable ceiling effects (7.5%). It demonstrated moderate correlation with ASCOT (r = 0.51, p < 0.001) and EQ-5D-5L (r = 0.52, p < 0.001) and a stronger correlation with the QCE-ACC (r = 0.57, p < 0.001). Residents with poor self-rated health and quality of life had significantly lower scores on the QOL-ACC. The internal consistency reliability of the QOL-ACC and its dimensions was good (α = 0.70-0.77). CONCLUSIONS: The QOL-ACC demonstrated good feasibility, construct validity and internal consistency reliability to assess aged care-related quality of life. Moderate correlations of the QOL-ACC and other instruments provide evidence of its construct validity and signifies that the QOL-ACC adds non-redundant and non-interchangeable information beyond the existing instruments. A stronger correlation with the QCE-ACC than other instruments may indicate that quality of life is more intimately connected with the care experience than either health- or social-related quality of life in residential aged care settings.

PURPOSE: To evaluate the construct (convergent and known group) validity of the Quality-of-Life-Aged Care Consumer (QOL-ACC), an older-person-specific quality-of-life measure designed for application in quality assessment and economic evaluation in aged care. METHODS: Convergent validity was assessed by examining relationships with other validated preference-based measures (EQ-5D-5L, ASCOT), quality of aged care experience (QCE-ACC) and life satisfaction (PWI) through an online survey. Known-group validity was assessed by testing the ability to discriminate varying levels of care needs, self-reported health and quality of life. RESULTS: Older people (aged ≥ 65 years) receiving community-aged care (N = 313) responded; 54.6% were female, 41.8% were living alone and 56.8% were receiving higher-level care. The QOL-ACC and its six dimensions were low to moderately and significantly correlated with the EQ-5D-5L (correlation co-efficient range, ρ = 0.39-0.56). The QOL-ACC demonstrated moderate and statistically significant correlations with ASCOT (ρ = 0.61), the QCE-ACC (ρ = 0.51) and the PWI (ρ = 0.70). Respondents with poorer self-reported health status, quality of life and/or higher-level care needs demonstrated lower QOL-ACC scores (P < 0.001), providing evidence of known-group validity. CONCLUSIONS: The study provides evidence of the construct validity of the QOL-ACC descriptive system. A preference-weighted value set is currently being developed for the QOL-ACC, which when finalised will be subjected to further validation assessments.

PurposeRetinitis pigmentosa (RP) is the most common retinal degeneration causing blindness. Although their clinical problems are amenable for the clinical diagnosis, their day-to-day problems for having to live with the disease are mostly unexplored. This study aims to explore and understand the issues and impact of people with RP on quality of life (QoL).MethodsA qualitative research methodology to facilitate the understanding of the experiences of people with RP was carried out. Data were collected through audio-recorded semi-structured interviews. Thematic analysis occurred through the process of line-by-line coding, aggregation, and theme development using the NVivo-10 software.ResultsTwenty-three interviews were conducted (mean age=56 years; females, 14). We identified five major QoL themes: (1) struggle to perform important day-to-day tasks; (2) concerns about disease progression, disease outcome and personal safety; (3) facing a lot of emotional and psychological challenges; (4) experiencing a myriad of visual symptoms; and (5) adopting different strategies to cope and manage stressful circumstances. Difficulty in performing important day-to-day tasks was the most prominent QoL issue among these people. Their major concerns were going blind and uncertainties about their future. They face a lot of emotional and psychological challenges to adapt to the physiological stress associated with the progressive vision loss. However, they adopt several coping strategies to manage the stressful circumstances.ConclusionsPeople with RP experience a myriad of QoL issues. Despite all the hardship, they remain optimistic and learn to accept their eye condition and move on in life.

We studied the rifampicin (RIF) and isoniazid (INH) resistant genes in Mycobacterium tuberculosis isolated from sputum samples of re-treated TB cases using phenotypic drug susceptibility test (DST) and rapid molecular method (Genotype; MTBDR plus, Hains Life Science, Nehren, Germany). Of the total 207 isolates included in this study, 90 (42.0%) were RIF resistant, 107 (50.7%) were INH resistant whereas 86 (41.5%) were multidrug resistant (MDR) by DST. According to genotypic analysis, 37.0% (77/207) were RIF resistant, 50.2% (105/207) INH resistant and 70 (33.8%) were MDR. Among the total 90 RIF resistant isolates, 85.5% (77/90) showed mutation in 81 bp of rpoB gene and the mutation locus were distributed as follows; MUT1 Asp516Val (16.7%; 15/90), MUT2A His526Tyr (6.6%; 6/90), MUT2B His526Asp (5.5%; 5/90) and MUT3 Ser531Lue (56.7%; 51/90). Among the total 107 INH resistant isolates, the mutation located in katG gene was 98.1% (105/107) and in inhA MUT1 gene was (16.8%; 18/107). The mutation locus were distributed as follows; MUT1 Ser315Thr (77.6%; 83/107), MUT2 Ser315Ile (3.7%; 4/107) in katG and in inhA MUT1Cys15Thr (16.8%; 18/107). The highest frequency of mutations in rpoB gene was found at the region of codon Ser531Leu (56.7%) while the frequency of mutation in katG and inhA gene were found at the region of codon Ser315Thr (77.6%) and Cyst15Thr (17.1%), respectively. The rapid molecular test kit used in this study was found to be sensitive as well as specific for detection of RIF and INH resistant gene and also helpful in early detection of MDR-TB.

In a short span of three months, nine patients of cryptococcal infection were diagnosed at the All India Institute of Medical Sciences (AIIMS), New Delhi with varied clinical presentation. Predisposing factors could be ascertained in two patients only. The diagnosis was based on the direct demonstration of the organism followed by successful culture supported by histopathology (in one patient) and radiology. The specific antigen was also detected in the body fluids. The increased awareness and greater suspicion helped in the diagnosis of these patients. Those who were diagnosed early, responded well with specific antifungal therapy.

Result of bacterial study on Oral Rehydration Solution (ORS) prepared in plain unboiled and boiled drinking water of Kathmandu valley is reported. Of the total 100 water samples collected from different sources and area all the samples, as a base line study, were subjected for the examination of bacterial presence. Eighty eight percent of the water samples studied were found to be unsatisfactory for drinking. Thirty five percent of the ORS prepared in unboiled water and kept for 24 hours at room temperature showed increased bacterial count whereas none of the ORS prepared in 5 minute boiled water and kept for 24 hour at room temperature showed any bacterial growth. Decreased bacterial count was not found in any of the ORS prepared in unboiled water. Typical coliform bacilli were found grown in 57.0% of the ORS prepared in unboiled water samples.
