A retrospective study on the prevalence of urinary tract infections in a tertiary care hospital in Sangareddy district of South India
Background: Urinary tract infections (UTI) affect the portion of the urinary tract including kidneys, ureters, bladder, and urethra, and are among the commonly acquired nosocomial infections. Diagnosis based on the culture and sensitivity profile of the organism is highly beneficial for appropriate antimicrobial therapy of the individual.Methods: A retrospective study of culture isolates obtained from urine samples from different departments of a tertiary care hospital was performed in the period January 2018 to March 2020 in the district of Sangareddy, Telangana, India.Results: A total 204 samples of 1886 exhibited significant growth of organisms i.e., ≥105 colony-forming units of bacteria per millilitre (CFU mL-1). The most common pathogen isolated was Escherichia coli (47.05%), followed by Klebsiella pneumoniae (15.68%), Staphylococcus aureus (10.78%), Pseudomonas aeruginosa (10.78%), Enterobacter spp. (7.84%) and, Candida albicans (7.84%). The presence of Gram-negative organisms was found to be more than Gram-positive organisms among the samples cultured. Resistance was found to be more towards Amoxicillin (57.14%), followed by oxacillin (34%), cefotaxime (23.62%), clarithromycin (12.08%), erythromycin (12.08%), azithromycin (9.34%), linezolid (3.84%) and vancomycin (2.19%).Conclusions: Increasing levels of antimicrobial resistance by uropathogens emphasize the importance of therapy based on the culture and sensitivity of the organisms. Many uropathogens exhibit multi-drugs resistance. Regular surveillance and monitoring are useful in controlling the increasing resistance
Comparison of the paper-based and electronic versions of the Dermatology Life Quality Index (DLQI): evidence of equivalence
BACKGROUND:
The use of patient-reported outcome measures in electronic format has been increasing. However, these formats are usually not validated or compared to the original paper-based formats, so there is no evidence that they are completed in the same way.
OBJECTIVES:
The aim of this study was to compare the conventional paper version and a web-based application version (iPad® ) of the DLQI to assess equivalence of scores.
METHODS:
The study employed a randomized cross-over design using a within-subjects comparison of the two formats of the questionnaire. International Society for Pharmacoeconomics and Outcomes Research (ISPOR) guidelines were followed. Subjects aged over 18 years with any confirmed skin condition were recruited from a teaching hospital dermatology outpatient clinic. Expected Intra-class correlation coefficient (ICC) was 0.9 (α = 0.05) RESULTS: A total of 104 patients were recruited, median age=53.5 years (IQR=37.3-67.8, 43% male). The Intraclass correlation coefficient (ICC) showed high concordance between the total DLQI scores from paper and iPad® versions (ICC = 0.98; 95% CI 0.97-0.99). Patients took a median of 78 seconds to complete the electronic version and 73 seconds for paper (p=0.008): 76% preferred the electronic version and perceived completion to take a shorter time.
CONCLUSIONS:
There is high concordance, and thus equivalence, between the iPad and paper versions of the DLQI, with an ICC of 0.98, and a clear patient preference for the iPad version
Measuring the impact of COVID-19 on the quality of life of the survivors, partners and family members: a cross-sectional international online survey
Objective: This study aimed to measure the impact of COVID-19 on the quality of life (QoL) of survivors and their partners and family members. Design and setting: A prospective cross-sectional global online survey using social media. Participants: Patients with COVID-19 and partners or family members (age ≥18 years). Intervention: Online survey from June to August 2020. Main outcome measure: The EuroQol group five dimensions three level (EQ-5D-3L) to measure the QoL of survivors of COVID-19, and the Family Reported Outcome Measure (FROM-16) to assess the impact on their partner/family member’s QoL. Results: The survey was completed by 735 COVID-19 survivors (mean age=48 years; females=563) at a mean of 12.8 weeks after diagnosis and by 571 partners and 164 family members (n=735; mean age=47 years; females=246) from Europe (50.6%), North America (38.5%) and rest of the world (10.9%). The EQ-5D mean score for COVID-19 survivors was 8.65 (SD=1.9, median=9; range=6–14). 81.1% (596/735) reported pain and discomfort, 79.5% (584/735) problems with usual activities, 68.7% (505/735) anxiety and depression and 56.2% (413/735) problems with mobility. Hospitalised survivors (20.1%, n=148) and survivors with existing health conditions (30.9%, n=227) reported significantly more problems with mobility and usual activities (pPeer reviewedFinal Published versio

Published by BMJ. http://creativecommons.org/licenses/by-nc/4.0/Objective: To assign clinical meanings to the Family Reported Outcome Measure (FROM-16) scores through the development of score bands using the anchor-based approach. Design and setting: A cross-sectional online study recruited participants through UK-based patient support groups, research support platforms (HealthWise Wales, Autism Research Centre-Cambridge University database, Join Dementia Research) and through social service departments in Wales. Participants: Family members/partners (aged ≥18 years) of patients with different health conditions. Intervention: Family members/partners of patients completed the FROM-16 questionnaire and a Global Question (GQ). Main outcome measure: Various FROM-16 band sets were devised as a result of mapping of mean, median and mode of the GQ scores to FROM-16 total score, and receiver operating characteristic-area under the curve cut-off values. The band set with the best agreement with GQ based on weighted kappa was selected. Results: A total of 4413 family members/partners (male=1533, 34.7%; female=2858, 64.8%; Prefer not to say=16, 0.4%; other=6, 0.14%) of people with a health condition (male=1994, 45.2%; female=2400, 54.4%; Prefer not to say=12, 0.3%; other=7, 0.16%) completed the online survey: mean FROM-16 score=15.02 (range 0–32, SD=8.08), mean GQ score=2.32 (range 0–4, SD=1.08). The proposed FROM-16 score bandings are: 0–1=no effect on the quality of life of family member; 2–8=small effect on family member; 9–16=moderate effect on family member; 17–25=very large effect on family member; 26–32=extremely large effect on family member (weighted kappa=0.60). Conclusion: The FROM-16 score descriptor bands provide new information to clinicians about interpreting scores and score changes, allowing better-informed treatment decisions for patients and their families. The score banding of FROM-16, along with a short administration time, demonstrates its potential to support holistic clinical practice.Peer reviewe
Comparative analysis of UWB balance Antipodal Vivaldi Antenna for array configuration
In this paper, an Ultra-wideband Balance
Antipodal Vivaldi Antenna in planar and h-plane array
configuration is presented. The comparison of four elements of
BAVA array in both planes has been observed. Each element
of an antenna printed on the glass-reinforced epoxy laminate
material (FR4) with a thickness of 1.5mm and relative
permittivity of 4.3. The dimension of every single element is
60.75mm x 66mm approximately. The array elements of both
planes almost cover the whole UWB frequency range with the
reflection coefficient of -10dB. Based on the simulation results,
the array elements in planar configuration showing good
reflection and works well at 3.2GHz frequency while the
configuration in h-plane the array elements works well at
7GHz of frequency. In planar configuration, the operating
frequency of antenna elements is shifting as a result of the
distance between inter elements which intensification in
wavelength. The array elements in h-plane produce more gain
up to 10.2 dB with good radiation patterns as compared to the
planar plane. The antenna design and optimization
development are verified using CST simulation software
UWB antenna based time-domain approach for through the walls gap estimation
This paper has introduced a novel experimental system adopted a time domain approach for estimating through wall distance and recognizes buried objects behind the wall. The designed and fabricated balanced antipodal Vivaldi antenna (BAVA) has been used for the development of UWB system. The working mechanism of an intended detection system based on time domain reflectometry (TDR) and ground-penetrating radar (GPR). A miniature pulse in the UWB range is generated by the vector network analyzer (VNA) to irradiate a barrier made of two walls separated by airgap between them. The signal radiations reflect partially from the front wall while remaining goes through for getting reflected from the rear wall. The VNA is used for measuring the time interval passed between the instant when an incident signal irradiates the first wall and the instant when the incident signal gets reflected from the rear wall. The investigational process of a system is carried out by UWB antenna probe. The detected information is attained using the values of reflection coefficient (S 11 ) represented in time domain measurements. Experimental results have been proved the ability to detect wall gap as well as the width estimation between two walls with high accuracy. The maximum percentage error has been found to not exceeding 4.5% in the worst condition
Translation and validation of the Polish language version of the Teenagers Quality of Life questionnaire (T-QoL)
Introduction:
Skin diseases affect patients at any age, but as each period in life is different, tools used to assess quality of life impairment should be adjusted according to the particular age group. Adolescence is a unique time, when young individuals go through many changes, making them especially vulnerable to stress.
Aim:
Translation and validation of a Polish language version of the Teenagers Quality of Life (T-QoL) questionnaire.
Material and methods:
T-QoL was translated following international guidelines. A group of 34 dermatological patients, aged 12–19 years old, with various skin diseases were given the T-QoL as well as the CDLQI or DLQI to complete. They were also asked to complete the T-QoL questionnaire for the second time after 3–5 days. Statistical analysis of the results was performed.
Results:
The Polish version of T-QoL is internally consistent (Cronbach a 0.893 for the whole questionnaire). Moreover, it presents very good convergent validity (ICC = 0.864). No statistics significant differences between each question were noticed between the first and second time of completing the form. T-QoL scores correlated significantly with DLQI ( p = 0.008, r = 0.636) and CDLQI ( p < 0.001, r = 0.777) scores.
Conclusions:
The Polish version of the T-QoL questionnaire is a reliable instrument with adequate convergent validity, consistency and reproducibility. It can be successfully used to measure quality of life impairment among teenagers
A systematic review of 207 studies describing validation aspects of the dermatology life quality index
This study systematically analysed peer-reviewed publications describing validation aspects of the Dermatology Life Quality Index (DLQI) and used Naicker’s Critically Appraising for Antiracism Tool to assess risk of racial bias. Seven online databases were searched from 1994 until 2022 for articles containing DLQI validation data. Methodology followed PRISMA guidelines, the protocol was registered in PROSPERO, and articles reviewed independently by two assessors. Of 1,717 screened publications, 207 articles including 58,828 patients from > 49 different countries and 41 diseases met the inclusion criteria. The DLQI demonstrated strong test–retest reliability; 43 studies confirmed good internal consistency. Twelve studies were performed using anchors to assess change responsiveness with effect sizes from small to large, giving confidence that the DLQI responds appropriately to change. Forty-two studies tested known-groups validity, providing confidence in construct and use of the DLQI over many parameters, including disease severity, anxiety, depression, stigma, scarring, well-being, sexual function, disease location and duration. DLQI correlation was demonstrated with 119 Patient Reported Outcomes/Quality of Life measures in 207 studies. Only 15% of studies explicitly recruited minority ethnic participants; 3.9% stratified results by race/ethnicity. This review summarizes knowledge concerning DLQI validation, confirms many strengths of the DLQI and identifies areas for further validation
