ABSTRACT

The emergence of Coronavirus disease 2019 (COVID- 19) has resulted in an unprecedented global health crisis. Tinnitus is the most commonly reported symptom when the COVID-19 impacts the auditory-vestibular system. There are a variety of management strategies for amelioration of tinnitus including Yoga. The present review deals with three issues: one, occurrence of tinnitus in persons affected by COVID-19; two, the impact of COVID-19 situation on tinnitus severity; and three, the potential of Yoga as an intervention strategy. Literature search was carried out through search engines like PubMed, Cochrane, Web of Science and Google scholar using keywords like 'tinnitus', 'COVID-19' and 'Yoga'. The relevant studies were identified and the findings summarized in a narrative manner. Based on the evidence obtained in the present review, the authors propose that yoga can be used as an effective strategy in overcoming the psychosocial factors associated with COVID-19 particularly in this pandemic and related lockdown situation. It is also proposed here that teleyoga can serve as a practical, feasible and safe mode for providing therapeutic services for tinnitus-related issues particularly in the present pandemic situation.

ABSTRACT

BACKGROUND AND AIM: The Telangana cancer care program is a proactive, comprehensive initiative encompassing infrastructure development, human resource skilling and ensuring financial protection to those below poverty line. The broad aim of this exercise was to identify modalities to augment the Telangana State Cancer Control Plan to implement a sustainable comprehensive cancer care model for Telangana. METHODS: We conducted in-depth interviews of stakeholders (17 patients and 25 health care providers) to identify barriers and challenges to access existing cancer care system in Telangana; calculated the magnitude of cancer and commensurate workload (in terms of visits to tertiary cancer care system for cancer management and human and equipment requirement) for the next 15 years (from 2022 to 2037). Using the anecdotal evidence and information from stakeholders' interviews, we developed patient-journey funnels for oral, breast, and cervical cancer patients to highlight patient leakages at various levels of cancer care. RESULTS: We estimated a 13%, 28%, and 44.7% increase in the number of new cancer cases and the resultant workload (number of visits to health care centre, chemotherapy sessions, radiotherapy sessions, surgeries, specialized human resources and equipment), for the year 2027, 2032, and 2037, respectively, compared to the year 2022. The stakeholders mentioned 'delayed access' to healthcare system as the main reason for the poor prognosis of patients. The common reasons cited for 'delayed access' were: poor cancer-literacy including prevailing myths and misconception, financial barriers, and rural residence. The patient journey funnel for cancer care revealed a major leakage from 'screened-positive' to 'diagnosis confirmation' step. The estimated patient leakage varied from ~70% to 90% from 'screened-positive' till 'treatment completion'. CONCLUSION: In this study, we anticipated a steady increase in the number of new cancers cases and resultant workload for the state of Telangana from the year 2022 to 2037. This may further be accompanied with limited access or utilization of cancer care system. To manage this public health issue, government should take appropriate measures to improve cancer literacy at the community level as well as increase human resources and necessary equipment.

ABSTRACT

AIMS: The aim of this study was to verify whether there is significant relationship between stages of mandibular canine calcification and skeletal maturation and to determine whether the same can be used as a reliable diagnostic aid to assess skeletal maturity. MATERIALS AND METHODS: The sample consisted of 50 males and 50 females aged between 8 and 15 years. Two radiographs namely orthopantomograph and handwrist radiograph were taken for this study. Skeletal age was ascertained from handwrist radiographs according to the method introduced by Fishman L.S. The developmental stages of mandibular canine were assessed according to Demirjian's stages of dental calcification. RESULTS: The relationship between canine stage calcification and skeletal maturity index was statistically significant in all stages. INTERPRETATION AND CONCLUSION: Mandibular canine calcification stages can be recommended as a supplemental diagnostic aid. Similar studies may be conducted in different population to rule out any possible racial and regional influences on growth characteristics.

ABSTRACT

OBJECTIVE: Protocol for clozapine rechallenge in patients with a history of clozapine-induced myocarditis. METHOD: Clozapine-related cardiovascular adverse effects including myocarditis and cardiomyopathy have limited its widespread use in treatment-resistant schizophrenia. Here, we present a case of clozapine-induced myocarditis and successful cautious rechallenge. Ms. AA, a young female patient with severe psychosis developed myocarditis during her initial clozapine titration phase, which was thus discontinued. Subsequent response to other medications was poor, and she remained significantly disabled. We reviewed blood-based biomarkers identified during the emergence of her index episode of myocarditis and developed a successful clozapine rechallenge protocol, based on careful monitoring of changes in these indices and a very slow clozapine re-titration. RESULTS AND CONCLUSIONS: This protocol may have utility in the management of patients with a history of clozapine-induced myocarditis.

ABSTRACT

OBJECTIVE: To assess the effects of using health social media on web activity. DESIGN: Individually randomised controlled parallel group superiority trial. SETTING: Twitter and Weibo. PARTICIPANTS: 170 Cochrane Schizophrenia Group full reviews with an abstract and plain language summary web page. INTERVENTIONS: Three randomly ordered slightly different 140 character or less messages, each containing a short URL to the freely accessible summary page sent on specific times on one single day. This was compared with no messaging. OUTCOME: The primary outcome was web page visits at 1 week. Secondary outcomes were other metrics of web activity at 1 week. RESULTS: 85 reviews were randomised to each of the intervention and control arms. Google Analytics allowed 100% follow-up within 1 week of completion. Intervention and control reviews received a total of 1162 and 449 visits, respectively (IRR 2.7, 95% CI 2.2 to 3.3). Fewer intervention reviews had single page only visits (16% vs 31%, OR 0.41, 0.19 to 0.88) and users spent more time viewing intervention reviews (geometric mean 76 vs 31 s, ratio 2.5, 1.3 to 4.6). Other secondary metrics of web activity all showed strong evidence in favour of the intervention. CONCLUSIONS: Tweeting in this limited area of healthcare increases 'product placement' of evidence with the potential for that to influence care. TRIAL REGISTRATION NUMBER: ISRCTN84658943.

ABSTRACT

Speech subsystems are susceptible to the effects of several factors including medications. The atypical antipsychotics can also adversely affect the speech because of its action on serotonin and dopamine neurotransmitters. The present study aims to analyze the speech characteristics associated with atypical antipsychotic risperidone. Speech of 92 patients on risperidone with or without trihexyphenidyl and/or clonazepam were compared with that of 31 persons who were not on any psychotropic medicines. Compared to control group, maximum phonation duration, sequential motion rate of diadochokinesia was reduced by about 3s and 1syllable/s respectively and s/z ratio was increased by 0.16 in patients with risperidone. Performance of larynx, lips and tongue sub-system and intelligibility of speech were also significantly reduced in risperidone group. Risperidone did impact the phonation and articulation sub-systems of speech mildly, which was independent of tardive dyskinesia and extrapyramidal symptoms. Randomized controlled prospective study looking into impact on speech and related effect on drug adherence, functioning and quality of life needs to be conducted with risperidone and other atypical antipsychotics.

ABSTRACT

OBJECTIVE: The purpose of this study was to evaluate the effect of lengthening of voice onset time and burst duration of selected speech stimuli on perception by individuals with auditory dys-synchrony. This is the second of a series of articles reporting the effect of signal enhancing strategies on speech perception by such individuals. METHODS: Two experiments were conducted: (1) assessment of the 'just-noticeable difference' for voice onset time and burst duration of speech sounds; and (2) assessment of speech identification scores when speech sounds were modified by lengthening the voice onset time and the burst duration in units of one just-noticeable difference, both in isolation and in combination with each other plus transition duration modification. RESULTS: Lengthening of voice onset time as well as burst duration improved perception of voicing. However, the effect of voice onset time modification was greater than that of burst duration modification. Although combined lengthening of voice onset time, burst duration and transition duration resulted in improved speech perception, the improvement was less than that due to lengthening of transition duration alone. CONCLUSION: These results suggest that innovative speech processing strategies that enhance temporal cues may benefit individuals with auditory dys-synchrony.

ABSTRACT

OBJECTIVE: This study aimed to evaluate the effect of lengthening the transition duration of selected speech segments upon the perception of those segments in individuals with auditory dys-synchrony. METHODS: Thirty individuals with auditory dys-synchrony participated in the study, along with 30 age-matched normal hearing listeners. Eight consonant-vowel syllables were used as auditory stimuli. Two experiments were conducted. Experiment one measured the 'just noticeable difference' time: the smallest prolongation of the speech sound transition duration which was noticeable by the subject. In experiment two, speech sounds were modified by lengthening the transition duration by multiples of the just noticeable difference time, and subjects' speech identification scores for the modified speech sounds were assessed. RESULTS: Subjects with auditory dys-synchrony demonstrated poor processing of temporal auditory information. Lengthening of speech sound transition duration improved these subjects' perception of both the placement and voicing features of the speech syllables used. CONCLUSION: These results suggest that innovative speech processing strategies which enhance temporal cues may benefit individuals with auditory dys-synchrony.

ABSTRACT

No instrument exists for the people of India to measure outcomes of voice disorders. The objective of this study was to develop a statistically robust tool for assessing voice disorder outcomes in the Indian population. A 32-item assessment tool called the Voice Disorder Outcome Profile (Voice-DOP) was developed after consultation with two different sets of speech-language pathologists and individuals with voice disorders. Voice-DOP measures voice disorder outcomes in three domains, physical, emotional, and functional. The questionnaire was given to 42 individuals with various voice disorders and 30 control subjects with no vocal pathology. The data obtained were subjected to measures of reliability (internal consistency and test-retest) and validity (content, construct, and concurrent). Results showed that Voice-DOP had high internal consistency (Cronbach's alpha levels from 0.49 to 0.84) and test-rest reliability (r=0.96-0.99). Voice-DOP differentiated the dysphonic group from the control group, and correlations of r=0.49-0.87 were obtained between the total Voice-DOP scores and the domain scores, findings suggesting adequate construct validity. Concurrent validity was supported by a significant correlation (r=0.51) between the Voice-DOP scores and the self-perception of severity by the individuals with dysphonia. A comparison of Voice-DOP scores between males and females revealed no significant difference in their outcomes. The conclusion of this study is that Voice-DOP is a sufficiently reliable and valid tool to measure voice disorder outcomes in the Indian population.

ABSTRACT

BACKGROUND: Sudarshana Kriya Yoga (SKY) has demonstrable antidepressant effects. SKY was tested for this effect in inpatients of alcohol dependence. METHODS: Following a week of detoxification management consenting subjects (n=60) were equally randomized to receive SKY therapy or not (controls) for a two-week study. SKY therapy included alternate day practice of specified breathing exercise under supervision of a trained therapist. Subjects completed the Beck Depression Inventory (BDI) before and after the two weeks of this intervention. Morning plasma cortisol, ACTH and prolactin too were measured before and at the end of two weeks. RESULTS: In both groups reductions in BDI scores occurred but significantly more so in SKY group. Likewise, in both groups plasma cortisol as well as ACTH fell after two weeks but significantly more so in SKY group. Reduction in BDI scores correlated with that in cortisol in SKY but not in control group. LIMITATIONS: Antidepressant effects of SKY were demonstrated in early abstinence that also had substantial spontaneous improvement. It is not known if this effect contributes to sustained abstinence. CONCLUSION: Results extend the antidepressant effects of SKY in alcohol dependence subjects. Reduction in stress-hormone levels (cortisol and ACTH) along with BDI reductions possibly support a biological mechanism of SKY in producing beneficial effects.

ABSTRACT

The objectives of this study were to (a) estimate the prevalence of auditory dys-synchrony in Mysore, a city of one million population in Southern India and, (b) present the results of audiological testing of this clinical population as well as the relationship between these figures. A register-based study design was employed wherein the results of audiological tests of all patients who visited the Department of Audiology, All India Institute of Speech and Hearing between January 2000 and December 2003 were reviewed. Results showed that the prevalence of auditory dys-synchrony was around 1 in 183 in individuals with sensory neural hearing loss. Behavioural thresholds and speech identification scores were variable. Around 60% of the individuals had no measurable speech identification scores. There was no relation between the hearing thresholds and speech identification scores or between otoacoustic emissions and speech identification scores. These results indicate that auditory dys-synchrony is not an extremely rare disorder.

ABSTRACT

BACKGROUND: Antipsychotic medication is a mainstay of treatment for schizophrenia. Risperidone and olanzapine are popular choices among the new generation drugs. OBJECTIVES: To determine the clinical effects, safety and cost effectiveness of risperidone compared with olanzapine for treating schizophrenia. SEARCH STRATEGY: We searched the Cochrane Schizophrenia Group's Register (Sept 2005) which is based on regular searches of, amongst others, BIOSIS, CENTRAL, CINAHL, EMBASE, MEDLINE and PsycINFO. References of all identified studies were inspected for further trials. We also contacted relevant pharmaceutical companies for additional information. SELECTION CRITERIA: We included all clinical randomised trials comparing risperidone with olanzapine for schizophrenia and schizophrenia-like psychoses. DATA COLLECTION AND ANALYSIS: We extracted data independently. For homogenous dichotomous data we calculated random effects, relative risk (RR), 95% confidence intervals (CI) and, where appropriate, numbers needed to treat/harm (NNT/H) on an intention-to-treat basis. For continuous data, we calculated weighted mean differences (WMD). MAIN RESULTS: We found no difference for the outcome of unchanged or worse in the short term (n=548, 2 RCTs, RR 1.00 CI 0.88 to 1.15). One study favoured olanzapine for the outcome of relapse/rehospitalisation by 12 months (n=279, 1 RCT, RR 2.16 CI 1.31 to 3.54, NNH 7 CI 3 to 25). Most mental state data showed the two drugs to be as effective as each other (n=552, 2 RCTs, RR 'no <20% decrease PANSS by eight weeks' 1.01 CI 0.87 to 1.16). Both drugs commonly cause adverse events: 75% given either drug experience an adverse event; 20% anticholinergic symptoms; both groups experienced insomnia although it was more frequent with risperidone (n=1588, 5 RCTs, RR 1.41 CI 1.15 to 1.72, NNH 15 CI 9 to 41); about 30% experienced sleepiness (n=1713, 6 RCTs, RR 0.92 CI 0.79 to 1.07). People given either drug often experienced some extrapyramidal symptoms (n=893, 3 RCTs, RR 1.18 CI 0.75 to 1.88); 25% of people using risperidone required medication to alleviate these symptoms (n=419, 2 RCTs, RR 1.76 CI 1.25 to 2.48, NNH 8 CI 4 to 25). People allocated to risperidone were less likely to gain weight compared with those given olanzapine and the weight gain was often considerable and of quick onset (n=984, 2 RCTs, RR gain more than 7% of their baseline weight in short term 0.47 CI 0.36 to 0.61, NNH 7 CI 6 to 10). Risperidone participants were less likely to leave the study due to metabolic side effects and weight gain compared with olanzapine (n=667, 1RCT, RR 0.19 CI 0.08 to 0.45). Patients on risperidone were more likely to experience abnormal ejaculation (n=370, 2 RCTs, RR 4.36 CI 1.38 to 13.76, NNH 20 CI 6 to 176). Both drugs are associated with high attrition rates; in the long term consistent findings show that 66% of those allocated risperidone left the study early compared with 56% given olanzapine (n=1440, 5 RCTs, RR 1.17 CI 1.08 to 1.27, NNH 11 CI 7 to 23). AUTHORS' CONCLUSIONS: We know very little of the effects of these drugs regarding service outcomes, general functioning and behaviours, engagement with services and treatment satisfaction from evaluative studies. There was generally a high rate of attrition in the trials and there appears to be little to differentiate between risperidone and olanzapine except on issues of adverse effects. Both drugs are associated with a reduction in psychotic symptoms but both commonly cause unpleasant adverse effects.

ABSTRACT

Fly ash is a common admixture used in concrete and may constitute up to 50% by weight of the total binder material. Incorporation of fly ash in Portland-cement concrete is highly desirable due to technological, economic, and environmental benefits. This article demonstrates the use of artificial intelligence neural networks for the classification of fly ashes in to different groups. Kohonen's Self Organizing Feature Maps is used for the purpose. As chemical composition of fly ash is crucial in the performance of concrete, eight chemical attributes of fly ashes have been considered. The application of simple Kohonen's one-dimensional feature maps permitted to differentiate three main groups of fly ashes. Three one-dimensional feature maps of topology 8-16, 8-24 and 8-32 were explored. The overall classification result of 8-16 topology was found to be significant and encouraging. The data pertaining to 80 fly ash samples were collected from standard published works. The categorization was found to be excellent and compares well with Canadian Standard Association's [CSA A 3000] classification scheme.

ABSTRACT

BACKGROUND: Auditory neuropathy is a disorder characterized by no or severely impaired auditory brainstem responses in presence of normal otoacoustic emissions and/or cochlear microphonics. Speech perception abilities in these individuals are disproportionate to their hearing sensitivity and reported to be dependent on cortical evoked potentials and temporal processing abilities. The disproportionate loss of auditory percept in presence of normal cochlear function is suggestive of impairment of auditory neural synchrony. METHODS: We studied the auditory evoked potentials and psychophysical abilities in 14 adults with auditory neuropathy to characterize their perceptual capabilities. Psychophysical tests included measurement of open set speech identification scores, just noticeable difference for transition duration of syllable /da/ and temporal modulation transfer function. Auditory evoked potentials measures were, recording of P1/N1, P2/N2 complex and mismatch negativity (MMN). RESULTS: Results revealed a significant correlation between temporal processing deficits and speech perception abilities. In majority of individuals with auditory neuropathy P1/N1, P2/N2 complex and mismatch negativity could be elicited with normal amplitude and latency. None of the measured evoked potential parameters correlated with the speech perception scores. Many of the subjects with auditory neuropathy showed normal MMN even though they could not discriminate the stimulus contrast behaviorally. CONCLUSION: Conclusions drawn from the study are: 1. Individuals with auditory neuropathy have severely affected temporal processing. 2. The presence of MMN may not be directly linked to presence of behavioral discrimination and to speech perception capabilities at least in adults with auditory neuropathy.

ABSTRACT

BACKGROUND: Antipsychotic medication is a mainstay of treatment for schizophrenia and risperidone and olanzapine are the most popular treatment choice of the new generation drugs. OBJECTIVES: To determine the clinical effects, safety and cost effectiveness of risperidone compared with olanzapine for treating schizophrenia. SEARCH STRATEGY: We searched the Cochrane Schizophrenia Group's Register (June 2004) which is based on regular searches of, amongst others, BIOSIS, CENTRAL, CINAHL, EMBASE, MEDLINE and PsycINFO. References of all identified studies were inspected for further trials. We also contacted relevant pharmaceutical companies for additional information. SELECTION CRITERIA: We included all clinical randomised trials comparing risperidone with olanzapine for schizophrenia and schizophrenia-like psychoses. DATA COLLECTION AND ANALYSIS: We extracted data independently. For homogenous dichotomous data we calculated random effects, relative risk (RR), 95% confidence intervals (CI) and, where appropriate, numbers needed to treat/harm (NNT/H) on an intention-to-treat basis. For continuous data, we calculated weighted mean differences (WMD). MAIN RESULTS: We found no difference for the outcome of unchanged or worse in the short term (n=548, 2 RCTs, RR 1.00 CI 0.88 to 1.15). One study, sponsored by the manufactures of olanzapine, favoured this drug for the outcome of relapse/rehospitalisation by 12 months (n=279, RR 2.16 CI 1.31 to 3.54, NNT 7 CI 4 to 25). Most mental state data showed the two drugs to as effective as each other (n=552, 2 RCTs, RR 'no <20% decrease PANSS by eight weeks' 1.01 CI 0.87 to 1.16). At least two thirds of people given risperidone or olanzapine experienced an adverse event (n=300, 2 RCTs, RR 1.16 CI 0.70 to 1.94). About 20% had anticholinergic symptoms (n=719, 3 RCTs, RR 1.12 CI 0.77 to 1.63) and 20% of both groups experienced insomnia (n=594, 3 RCTs, RR 1.33 CI 0.95 to 1.85) and approximately 33% sleepiness (n=719, 4 RCTs, 0.99 CI 0.79 to 1.23). One third of people given either drug experienced some extrapyramidal symptoms (n=893, 3 RCTs, RR 1.18 CI 0.75 to 1.88) but 25% of people using risperidone require medication to alleviate extrapyramidal adverse effects (n=419, 2 RCTs, RR 1.76 CI 1.25 to 2.48, NNH 8 CI 4 to 25). People allocated to risperidone were less likely to gain weight compared with those given olanzapine and the weight gain resulting from olanzapine can be considerable and of rapid onset (n=377, 1 RCT, RR gain more than 7% of their baseline weight 0.40 CI 0.23 to 0.70, NNT 8 CI 6 to 17). Risperidone may cause more sexual dysfunction than olanzapine (n=370, 2 RCTs, RR abnormal ejaculation 4.36 CI 1.38 to 13.76, NNH 20 CI 6 to 176; n=31, 1 RCT, RR impotence 2.43 CI 0.24 to 24.07). Within trials both drugs are associated with equal attrition (n=1217, 7 RCTs, RR leaving the study early 1.17 CI 0.92 to 1.49). AUTHORS' CONCLUSIONS: Data regarding quality of life and economic outcomes are difficult to interpret, and for both these highly marketed new drugs we know very little from evaluative studies regarding service outcomes, general functioning and behaviour, engagement with services and treatment satisfaction. There is little to differentiate between risperidone and olanzapine except on the issue of adverse effects and both these drugs have unpleasant adverse effects. Risperidone is particularly associated with movement disorders and sexual dysfunction. Olanzapine can cause considerable rapid weight gain.This review highlights the need for large, independent, well designed, conducted and reported pragmatic randomised studies.
