Knowledge, Attitude and Practice on Vocal Abuse and Vocal Hygiene among Diverse Occupational Voice Users in Jodhpur, Rajasthan.

Background: Voice disorders in occupations connected with excessive voice use can be attributed to the inappropriate use of voice and poor vocal hygiene. Therefore, it is essential for persons in such occupations to be aware of vocal abuse, vocal hygiene, practices and their influence on maintaining healthy voice. Objectives: To assess knowledge, attitude and practice on vocal abuse and vocal hygiene among diverse occupational voice users in Jodhpur. Methodology: A cross-sectional study was conducted in Jodhpur district, Rajasthan. Data was collected from 424 participants (106 Doctors, 106 Teachers, 106 Advocates, 106 Vendors) from May 2023 to July 2023 by administrating a pretested semi structured questionnaire. Microsoft Excel and IBM SPSS (V. 23) statistical software were used for descriptive and inferential statistical analysis. Results: Majority (92%) of the participants felt that their quality of voice was good. About 55% participants were not aware about the term vocal abuse (Doctors 17.9%, Teachers 39.6%, Advocates 79.2%, Vendors 44.3%). Around 56% participants (Doctors 63.3%, Teachers 66.0%, Advocates 32.1%, Vendors 61%) had negative attitude towards vocal hygiene practices. About 47% of the participants preferred home remedies and 44.3% (Doctors 72.6%, Teachers 48.1%, Advocates 41.5%, Vendors 15.1%) preferred to consult ENT specialist for their voice related problem. Perception of vocal abuse on vocal health and hygiene practices was found to statistically significant (p = 0.001) among the different category of occupations. Conclusion: In this perception-based, cross-sectional study it was found that majority of the participants were neither aware about term vocal abuse nor followed vocal hygiene practices. In view of the above findings it is strongly recommended that excessive voice users should be made aware of vocal hygiene practices & repeated reinforcement of the same is required to prevent voice related problem.

Is anxiety a public health problem among older adults in India: Results from a systematic review and meta-analysis.

For medical fraternity, health system and policymakers to undertake effective countermeasures, a comprehensive assessment of the prevalence of anxiety among older adults is required; hence, we conducted a systematic review and meta-analysis using data pooled from surveys across the country. The search strategy was developed using medical subject headings (MeSH) terms and free-text keywords. We searched PubMed and Scopus for articles to report the prevalence of anxiety among older adults. The appraisal tool for cross-sectional studies was used for quality assessment. Prevalence from different studies was pooled together using the inverse variance heterogeneity method. Sensitivity analyses were performed to assess the impact of included studies' methodological quality on pooled results and to investigate potential causes of heterogeneity. Twenty-three studies were included in this systematic review. The overall pooled estimate of the prevalence of anxiety in older adults was 18.7% (95% CI: 2.4, 38.8). The studies had a high degree of heterogeneity. Publication bias was assessed using a Doi plot which showed an luis furuya-kanamori (LFK) index of 1.21 indicating minor asymmetry. Like other parts of the world, India has witnessed a rise in the number of elderly due to lower fertility rates, higher life expectancies and a shift in illness patterns from communicable to non-communicable. The number of elderly people suffering from diseases of mental health is expected to rise dramatically. This review consolidates the existing evidence to showcase anxiety as an upcoming public health problem requiring due focus from policymakers and health systems.

Effectiveness of ayurvedic formulation, NAOQ19 along with standard care in the treatment of mild-moderate COVID-19 patients: A double blind, randomized, placebo-controlled, multicentric trial.

BACKGROUND: Medicines in indigenous systems such as Ayurveda have strong antimicrobial activity but double-blind randomized control trials are infrequent in this system of medicine. The efficacy of a new ayurvedic formulation was evaluated during the pandemic. METHODS: 150 mild-moderate COVID-19 patients were enrolled and randomized in 1:1 to NAOQ19 and placebo group. RT-PCR was done on Day 3, 5 and 7. CBC, CRP, LFT, and KFT were assessed at baseline and exit. Duration of hospital stay was noted and clinical assessment was also performed. RESULT: The results demonstrated more people turning RT-PCR negative in the NAOQ19 group compared to the placebo group on day 3 (p-value = 0.033). The mean time duration to turn RT-PCR negative was significantly lower in the NAOQ19 group (4.6 days) compared to placebo group (5.2 days) (p-value = 0.018). There was significant reduction in hospital stay among patients in the NAOQ19 arm who were discharged earlier (5.6 days) compared to placebo group (6.4 days) (p-value = 0.046). Patients in NAOQ19 arm did not show any adverse life-threatening events. CONCLUSION: The ayurvedic preparation given along with standard of care therapy reduced the duration of hospital stay and there was earlier conversion to RT-PCR negative.The integrated approach can help to reduce patient workload in the hospitals as well as limit the transmission of the virus in the community.

Exploring internet addiction and its associated factors among college students in Western Rajasthan, India: A mixed-methods study.

Background: With near universal use of internet by college students, there is propensity for internet addiction (IA) among them. This study aimed to estimate the prevalence and predict the factors for internet addiction among college students in Jodhpur, Rajasthan, India, and qualitatively explore the factors associated with internet addiction. Materials and Methods: Explanatory sequential (QUAN-QUAL) mixed-methods design was used. A cross-sectional questionnaire-based survey was conducted among three streams of undergraduate colleges (health, engineering, and others). Survey instruments included Young's internet addiction test (IAT), Pittsburgh Sleep Quality Index (PSQI), and Depression, Anxiety, and Stress Scale-21 (DASS-21) Items. Focus group discussions (FGDs) and in-depth interviews (IDIs) among the students with mild-to-moderate levels of addiction were conducted to understand the reasons for excessive internet use. Results: The prevalence of internet addiction (IA) among the college students was 51% and the rates for mild, moderate, and severe addiction were 31.8%, 18.5%, and 0.7%, respectively. Predictors of IA were male gender, age in years, age of first internet use in years, urban origin, accessing internet at college, mobile internet use, using internet to make online friendship, sleep disturbance, depression, anxiety, and stress. Qualitative study identified five major themes related to situations initiating internet use for nonacademic purpose, content of internet use, triggers for internet overuse/addiction (IA), perceived impact of IA, and measures to overcome IA. Conclusions: Internet addiction was found to be highly prevalent in college students across various streams. Qualitative results provide deeper insights into IA among college students. It is imperative to screen for IA among the students and devise suitable preventive interventions, which can be easily implemented at community level.

Musculoskeletal disorders among doctors and nursing officers : an occupational hazard of overstrained healthcare delivery system in western Rajasthan, India.

BACKGROUND: The present study was conducted to estimate the prevalence and distribution of MSDs in different anatomical regions among Doctors and NO and to determine their ergonomic risk factors and predictors. METHODS: This cross-sectional study was conducted in an apex institution in Western India. The socio-demographic information, medical and occupational history, and other personal and work-related attributes were captured using a semi-structured questionnaire, which was developed and finalized by piloting on 32 participants (who were not part of the study). Nordic Musculoskeletal and International Physical Activity Questionnaires were used to assess MSDs and Physical activity. Data were analyzed using SPSS v.23. Prevalence of Musculoskeletal Symptoms (M.S.), Multisite Musculoskeletal Symptoms (MMS), and Widespread Musculoskeletal Symptoms (WMS) were calculated. A comparison was made to estimate the burden and distribution of MSD among Doctors and Nursing officers. Logistic regression was applied to identify the predictors of MSDs and pinpoint the risk factors associated with MSDs. RESULTS: A total of 310 participants, of which 38.7% were doctors, and 61.3% were Nursing Officers (NOs) were included in the study. The mean age of the respondents was 31.63 ± 4.9 years. Almost 73% (95%CI: 67.9-78.1) of participants had MSD in the last 12 months, with approximately 41.6% (95%CI: 36.1-47.3) suffering from MSDs in the previous seven days of the survey. The lower back (49.7%) and the neck (36.5%) were the most affected sites. Working in the same position for a long time (43.5%) and not taking adequate breaks (31.3%) were the highest self-reported risk factors. Females had significantly higher odds of having pain in the upper back [aOR:2.49(1.27-4.85)], neck [aOR:2.15(1.22-3.77)], shoulder [aOR:2.8 (1.54-5.11)], hips [aOR:9.46 (3.95-22.68)] and knee [aOR:3.8(1.99-7.26)]. CONCLUSIONS: Females, who are NOs, work for > 48 h per week, and fall in the obese category were significantly at more risk of developing MSDs. Working in an awkward position, treating an excessive number of patients in a day, working in the same position for a long period, performing repeated tasks, and not having enough rest breaks were significant risk factors for MSDs.

Traditional Newborn Care Practices in a Tribal Community of Tamilnadu, South India: A Mixed Methods Study.

Background and Objectives: Traditional newborn rearing practices play a vital role in neonatal morbidity and mortality. In this context, a concurrent mixed method study was conducted to identify the traditional practices in newborn care in tribal villages of Sittilingi Panchayat of Tamil Nadu, South India. Methods: The quantitative data were collected by a community-based cross-sectional study among 59 mothers of infants. Qualitative component included two focus group discussions (FGD) each with seven mothers and one traditional dai. Results: About 38.9% of newborns received colostrum, and 61.1% had prelacteal feeds. Majority (84.7%) of newborns had received appropriate thermal care. More than two-thirds (71.2%) of newborns were given bath before umbilical cord dropped off. During bathing, 83.1% were massaged and 67.8% had their vernix removed. Practice of blowing into nostrils (45.7%), substance application on the cord (94.9%), tepid sponging during fever (28.8%), sweet flag application over umbilicus for colic (8.5%), herbal medications during diarrhea (40.6%) and cold (25.4%), exposure to sunlight (67.8%) during jaundice, oil instillation in nostrils (76.3%), and ears (32.2%) to protect against infection were reported. Majority reported approaching traditional health practitioners during illness. Similar practices were reported in the FGDs. The beliefs related to these practices were explored. Conclusion: Both beneficial and harmful practices in newborn care were identified. Primary health care workers like ASHAs could be trained to recognize traditional newborn practices in their field areas to deliver appropriate behavior change communication to preserve safe practices and avoid harmful practices to improve newborn health.

High-performance superconducting quantum processors via laser annealing of transmon qubits.

Scaling the number of qubits while maintaining high-fidelity quantum gates remains a key challenge for quantum computing. Presently, superconducting quantum processors with >50 qubits are actively available. For these systems, fixed-frequency transmons are attractive because of their long coherence and noise immunity. However, scaling fixed-frequency architectures proves challenging because of precise relative frequency requirements. Here, we use laser annealing to selectively tune transmon qubits into desired frequency patterns. Statistics over hundreds of annealed qubits demonstrate an empirical tuning precision of 18.5 MHz, with no measurable impact on qubit coherence. We quantify gate error statistics on a tuned 65-qubit processor, with median two-qubit gate fidelity of 98.7%. Baseline tuning statistics yield a frequency-equivalent resistance precision of 4.7 MHz, sufficient for high-yield scaling beyond 103 qubit levels. Moving forward, we anticipate selective laser annealing to play a central role in scaling fixed-frequency architectures.

Calibrated Decoders for Experimental Quantum Error Correction.

Arbitrarily long quantum computations require quantum memories that can be repeatedly measured without being corrupted. Here, we preserve the state of a quantum memory, notably with the additional use of flagged error events. All error events were extracted using fast, midcircuit measurements and resets of the physical qubits. Among the error decoders we considered, we introduce a perfect matching decoder that was calibrated from measurements containing up to size-four correlated events. To compare the decoders, we used a partial postselection scheme shown to retain ten times more data than full postselection. We observed logical errors per round of 2.2±0.1×10^{-2} (decoded without postselection) and 5.1±0.7×10^{-4} (full postselection), which was less than the physical measurement error of 7×10^{-3} and therefore surpasses a pseudothreshold for repeated logical measurements.

Rapid Response Preparedness for Management of Post-Covid Invasive Rhino-Orbito-Cerebral Fungal Infections: Experience from a Tertiary Care Government Institute in India.

Effect of heterotopic ossification after bryan-cervical disc arthroplasty on adjacent level range of motion: A finite element study.

BACKGROUND: Quantitative bone re-modelling theories suggest that bones adapt to mechanical loading conditions. Follow-up studies have shown that total disc replacement (TDR) modifies stress patterns in the bones, leading to heterotopic ossification (HO). Although there are a few studies on HO using finite element models (FEM), its effect on the adjacent levels and change in range of motion (ROM) have not been adequately investigated. This study interfaces the HO using bone re-modelling algorithm with a finite element solution and investigates the subsequent changes in segmental ROM. METHODS: A FEM of the human cervical spine (C3-C7) was developed for this study, with material properties obtained from literature. The motion of the segments in the sagittal, frontal and transverse planes under combined loading conditions of 1 Nm moment and 73.6 N compression were validated against experimental corridors. The natural disc between the C5-C6 segment was replaced with the Bryan artificial cervical disc, and changes in sagittal ROM were compared before and after HO. The process of HO was simulated using a bone remodelling algorithm using strain energy density (SED) as the mechanical stimuli. RESULTS AND CONCLUSION: Our study demonstrates the feasibility of using SED calculations from the flexion-extension loading conditions for prediction of HO after ADR. The current findings suggest that the nature of trabecular stresses, and the subsequent rate and location of HO formation could differ based on the geometric design and nature of constraint for different artificial discs. The Bryan disc significantly reduced ROM at the implanted level in flexion. However, in extension, ROM increased at the implanted level and decreased slightly at the adjacent levels. After HO, ROM drastically reduced at the implanted level in both extension and flexion, and showed a minor increase in the adjacent levels, indicating that biomechanical behavior of high-grade HO is similar to a fused segment, thereby reducing the intended and initial motion preservation.

New-onset hyperglycaemia and prolonged systemic corticosteroids therapy in mild COVID-19 patients as major risk factors for invasive mucormycosis: a preliminary study.

Background and Purpose: Rapid surge of invasive mucormycosis has surprised the Indian healthcare system amidst the coronavirus disease-19 (COVID-19) pandemic. Hence, there is an urgent need to find the risk factors for the sudden rise in cases of invasive mucormycosis among COVID-19 patients. This study aimed to find crucial risk factors for the sudden surge of invasive mucormycosis in India. Materials and Methods: This case-control study included 77 cases of COVID-19 associated mucormycosis (CAM) who matched the controls (45 controls) in terms of age , gender, and COVID-19 disease severity. The control group included subjects that matched controls without mucormycosis confirmed by reverse transcription-polymerase chain reaction at our tertiary care center during April-May 2021. Probable predisposing factors, such as duration of diabetes mellitus (DM), history of recent hospitalization, duration of hospital stay, mode of the received oxygen supplementation, and use of steroids, zinc, vitamin c, and any other specific drugs were collected and compared between the two groups. Moreover, the laboratory parameters, like glycated hemoglobin (HbA1c), highly sensitive C-reactive protein (hs-CRP), and erythrocyte sedimentation rate (ESR) were analyzed to find out the significant association with CAM. Results: DM (Odds ratio=7.7, 95% CI 3.30-18.12; P=<0.0001) and high glycated hemoglobin level (HbA1c>7.5 gm %) (odds ratio=6.2, 95% CI 1.4-26.7; P=0.014) were significant risk factors for the development of invasive mucormycosis among the COVID-19 cases. A higher number of mild COVID-19 cases developed CAM, compared to the moderate to severe cases (59.7% vs 40.3%). Use of systemic corticosteroids (odd ratio=5 with 95% CI 1.5-16.9; P=0.007) was found to be a risk factor for invasive mucormycosis only in mild COVID-19 cases. Use of oxygen, zinc, and vitamin C supplementation, and proprietary medicine did not lead to a significant risk of invasive mucormycosis in cases, compared to controls. Cases with invasive mucormycosis had a higher level of inflammatory markers (hs-CRP and ESR, P=<0.001 and 0.002, respectively), compared to the controls. Conclusion: Uncontrolled and new-onset DM and the use of systemic corticosteroids in mild cases were significantly associated with a higher risk of invasive mucormycosis in COVID-19 cases. There should be a strong recommendation against the use of systemic corticosteroids in mild COVID-19 cases.

Perspectives about Professionalism among Undergraduate Students in a Medical College in India: A Qualitative Study.

BACKGROUND: Professionalism has been recognized as an important competency of a doctor by various regulatory bodies. OBJECTIVES: The purpose of the study was to explore the perceptions of medical undergraduate students and to assess their attitude on professionalism. MATERIALS AND METHODS: It was a qualitative study in which four focus group discussions were conducted, one for each year of course. RESULTS: A total of seven themes emerged after the qualitative analysis of the data, namely qualities of a good doctor, need of teaching professionalism, ways of learning professionalism by medical students, ways of teaching professionalism, assessment of professionalism, factors promoting professionalism, and factors hindering professionalism. The students perceived that a good doctor should be committed to excellence, responsive and accountable to patients, profession and community, selfless, healthy, good communicator, ethical and law abiding, practice integrity, and social justice. The students preferred to learn professionalism by role modeling by faculties and case-based scenario discussions. CONCLUSION: Medical undergraduate students should be briefed about the need and importance of professionalism through small-group discussions involving narratives, case scenarios, and role modeling by faculty. Professionalism of both students and faculties should be assessed and appropriate action taken.

Observation of an environmentally insensitive solid-state spin defect in diamond.

Engineering coherent systems is a central goal of quantum science. Color centers in diamond are a promising approach, with the potential to combine the coherence of atoms with the scalability of a solid-state platform. We report a color center that shows insensitivity to environmental decoherence caused by phonons and electric field noise: the neutral charge state of silicon vacancy (SiV0). Through careful materials engineering, we achieved >80% conversion of implanted silicon to SiV0 SiV0 exhibits spin-lattice relaxation times approaching 1 minute and coherence times approaching 1 second. Its optical properties are very favorable, with ~90% of its emission into the zero-phonon line and near-transform-limited optical linewidths. These combined properties make SiV0 a promising defect for quantum network applications.

Norms for a neuropsychological test battery to diagnose dementia in the elderly: A study from Sri Lanka.

AIMS: To pilot a neuropsychological battery for diagnosing dementia and provide normative scores in an elderly Sri Lankan sample. MATERIALS AND METHODS: Consecutive subjects over the age of 60 yrs were administered tests assessing the individual domains of language, verbal episodic memory, visual perceptuospatial skills and executive functions in the Sinhala language. RESULTS: There were a total of 230 subjects in the final sample. The mean age of the entire sample was 69 years, mean education level was 12 years and the sample comprised 53% female. One-month test-retest reliability ranged from 0.71 to 0.85 for the various tests. Most tests were significantly influenced by age and education level but not gender. The exceptions to this were some language subtests (repetition, grammar comprehension and word picture matching) and two tests of executive functioning (maze completion and alternate target cancellation), which were uninfluenced by age. The subtests where ceiling performance was attained by almost all subjects were repetition, grammar comprehension and word picture matching from the language domain, dot position discrimination from the visuospatial domain and maze completion test from the executive function domain. Scores for various tests after stratifying subjects by age and educational level are given. CONCLUSIONS: The tests were well received and could provide a basis for cognitive profiling in similar settings elsewhere.

Demonstration of a quantum error detection code using a square lattice of four superconducting qubits.

The ability to detect and deal with errors when manipulating quantum systems is a fundamental requirement for fault-tolerant quantum computing. Unlike classical bits that are subject to only digital bit-flip errors, quantum bits are susceptible to a much larger spectrum of errors, for which any complete quantum error-correcting code must account. Whilst classical bit-flip detection can be realized via a linear array of qubits, a general fault-tolerant quantum error-correcting code requires extending into a higher-dimensional lattice. Here we present a quantum error detection protocol on a two-by-two planar lattice of superconducting qubits. The protocol detects an arbitrary quantum error on an encoded two-qubit entangled state via quantum non-demolition parity measurements on another pair of error syndrome qubits. This result represents a building block towards larger lattices amenable to fault-tolerant quantum error correction architectures such as the surface code.

Mild cognitive impairment: Profile of a cohort from a private sector memory clinic.

BACKGROUND: Private hospital memory clinics might see a different clientele than university or academic institutes due to referral biases. OBJECTIVE: To characterize the profile of patients with mild cognitive impairment (MCI) from a private sector memory clinic. MATERIALS AND METHODS: MCI was diagnosed according to revised clinical criteria of Petersen et al. For a subset of patients with MCI medial temporal atrophy and cerebral small vessel disease (white matter lesions and lacunes) were rated on magnetic resonance imaging (MRI) scans and analyzed for their contribution towards cognitive impairment. RESULTS: Subjects with MCI formed one-third (113/371) of this memory clinic sample from a private hospital. MCI could be effectively diagnosed and subtyped using a brief cognitive scale (Concise Cognitive Test (CONCOG)). The amnestic MCI (single and multiple domains) subtype comprised the majority of cases with MCI. In a subsample of 33 patients, lacunar infarcts were more common than white matter lesions and hippocampal atrophy and were inversely associated with verbal fluency. CONCLUSIONS: MCI may be more commonly encountered in private hospital settings probably due to early referrals. It is possible to diagnose and subtype MCI using a brief cognitive instrument such as the CONCOG. In this sample, lacunar infarcts were more commonly encountered than medial temporal atrophy in such patients.

Implementing a strand of a scalable fault-tolerant quantum computing fabric.

With favourable error thresholds and requiring only nearest-neighbour interactions on a lattice, the surface code is an error-correcting code that has garnered considerable attention. At the heart of this code is the ability to perform a low-weight parity measurement of local code qubits. Here we demonstrate high-fidelity parity detection of two code qubits via measurement of a third syndrome qubit. With high-fidelity gates, we generate entanglement distributed across three superconducting qubits in a lattice where each code qubit is coupled to two bus resonators. Via high-fidelity measurement of the syndrome qubit, we deterministically entangle the code qubits in either an even or odd parity Bell state, conditioned on the syndrome qubit state. Finally, to fully characterize this parity readout, we develop a measurement tomography protocol. The lattice presented naturally extends to larger networks of qubits, outlining a path towards fault-tolerant quantum computing.

The concise cognitive test for dementia screening: reliability and effects of demographic variables as compared to the mini mental state examination.

BACKGROUND: The Mini Mental State Examination (MMSE) is widely used for dementia screening but has several shortcomings such as prominent ceiling effects, inadequate sensitivity to mild cognitive impairment, and uneven sampling of the major cognitive domains. AIMS: In this study, we pilot a new dementia screening test - the Concise Cognitive Test (CONCOG) - designed to overcome the above short comings and describe the reliability measures and age, education, and gender effects. The CONCOG has a total score of 30, and has subtests for orientation, naming, registration, free recall and recognition of four words, semantic verbal fluency and copying. PATIENTS AND METHODS: Participants were screened to exclude those with any neurological or psychiatric disease, simultaneously administered the CONCOG, and a Hybrid Mini Mental State Examination (HMMSE) adapted from Folstein's MMSE and Ganguli's Hindi Mental State Examination. RESULTS: The study sample had 204 subjects over the age of 60 years with a mean of 73 years and education level of 8 (4.5) years. Internal consistency for the CONCOG (Cronbach's alpha) was 0.74, inter-rater reliability (Kendall's tau-b) was 0.9, and the one-month test-retest reliability (Kendall's tau-b) was 0.7. Age and education level, but not gender, significantly influenced performance on both scales. Although the influence of age on the two scales was to a similar degree, the HMMSE was more affected by education than the CONCOG. Of 204 subjects, only 12 (5.7%) subjects obtained the maximum score on the CONCOG compared with 30 (14.1%) subjects on the HMMSE. The CONCOG took less than 10 minutes to complete in this sample. Age and education stratified norms are presented for the CONCOG. CONCLUSIONS: The CONCOG is a reliable cognitive screening measure. It has negligible ceiling effects, is less influenced by education compared with the HMMSE, and offers subscale scores for the major cognitive domains.
