Social anxiety among trainee audiologist and speech language pathologist in Bengaluru: a cross sectional study

Background: Audiologist and Speech language pathologist (ASLPs) are a group of professionals specialized in communication disorders. Their work responsibilities require them to be interacting with people with different backgrounds, education and ages who seek assistance from these young professionals. It is important to know whether the professionals who are meant to deal with individuals with communication disorders are themselves going through social anxiety or not. Methods: A questionnaire was prepared and was used for assessing social anxiety among trainee undergraduate and postgraduate ASLP’s. Data was collected via Google form further was analyzed using SPSS version 20.0. Results: Total 124 students participated in the study (20 males and 104 females). Cronbach’s test was administered to check the internal consistency of questionnaire. The overall questionnaire had a global alpha of 0.926 and global alphas for different scenarios of the questionnaire were 0.865 and 0.894 respectively indicating high internal consistency. The test retest stability for the total score found to be high with r =0.773and p<0.01. Social anxiety score differs significantly with respect to ‘Traumatic life events’ and ‘Age’. Conclusions: The study was able to deliver the answers to the questions of the researcher, that is, first, the study was able to assert the use of the questionnaire in the target population. Second, study found a statistically significant difference on anxiety scores between different scenarios i.e, social and professional life.

Is Disease a Threat to Identity? A Systematic Review of Parkinson’s Disease and Personal Identity

Introduction: Parkinson’s disease (PD) is a neurological condition that impacts the physical and psychological functioning of the patients. The physical and cognitive changes come with social stigma and threats to roles previously associated with their identities. Objectives: The current paper attempts to study the influence of the disease on the personal identity of the patients. Methods: A systematic review was done on PD and personal identity following the Preferred Reporting Items for Systematic Reviews and Meta‑Analyses 2020 guidelines. The Consolidated Criteria for Reporting Qualitative Research checklist was used to assess the quality of the papers. The selected papers were synthesized to understand the relationship between PD and personal identity. Results: The emerging themes were: (1) dissociation of old personal identity: (1.1) Influence of physical symptoms, (1.2) influence of society and stigma, and (1.3) threats to roles associated with identity and (2) changing family dynamics. AModel of Personal, Family, and Disease Dynamics was also developed based on clinical first‑hand experience with the patients and the review. Conclusion: The personal identity of the PD patients shifts drastically as a result of their physical and psychosocial experiences. This also results in changed family dynamics, with the patient feeling sidelined due to loss of control and responsibilities in the family.

Molecular characterization of colistin-resistant Klebsiella pneumoniae & its clonal relationship among Indian isolates

Background & objectives: Klebsiella pneumoniae (KP), a common cause of invasive infections, is often extensively drug resistant in India. At present, studies on resistance mechanism and clonal relationship of KP from India are limited. The present study was undertaken to determine the resistance mechanism and clonal relationship of colistin-resistant isolates obtained from various specimens. Carbapenemases were also determined since the isolates were carbapenem resistant. Methods: Sixty five isolates from blood, exudates and respiratory specimens collected between 2016 and 2017 were studied. Colistin minimum inhibitory concentration (MIC) was performed by broth-micro dilution method. Multiplex PCR was carried out to determine carbapenemases. Targeted sequencing was performed to determine mutations in mgrB, phoP, phoQ and multilocus sequence typing was performed to determine the prevalent clones. Results: Colistin MIC ranged from 4 to 256 ?g/ml. SHV, TEM and CTX-M were co-produced in 60 per cent and OXA48-like in 71 per cent. Thirteen isolates had mutations in mgrB. Mutations included a premature stop codon at 21st amino acid, the presence of insertion sequences such as IS903, IS Kpn 14 and ISK pn 26; and elongation of mgrB. Novel mutations were also observed among phoP and phoQ genes. Colistin resistance due to mcr genes was absent. Fifteen clonal types were seen with ST231, ST14 and ST2096 being predominant. Interpretation & conclusions: This study revealed the changing trend of carbapenem resistance mechanism predominantly to OXA48-like from NDM. Known mgrB mutations and novel mutations in phoP and phoQ were detected. There was no plasmid-mediated colistin resistance. ST14 and ST231 were international clones associated with carbapenem resistance. Colistin-resistant KP was of diverse clones with predominantly ST231, ST14 and ST2096.

Home-based management of severely acute malnutrition: feasibility of ethically designed, community-based randomised clinical trials

The Indian Council of Medical Research had, on May 31, 2011, called for research proposals on severely acute malnourished (SAM) children to generate evidence for the development of practical and scalable regimens to medically rehabilitate children suffering from SAM, without serious complications, at the home/community level and/or peripheral inpatient facilities. The primary outcomes of the proposed research study are recovery from SAM in the short term, as well as sustenance of recovery (for at least six months after the initiation of treatment). The secondary outcomes are the acceptability, feasibility and safety of the regimes being tested. It was suggested that the studies be designed as individual or cluster randomised or quasi randomised controlled trials (RCTs). This paper analyses the methodological, operational, and most importantly, ethical challenges and implications of conducting community-based RCTs involving SAM children. The paper dwells in detail on why and how the RCT design is inappropriate and unsuitable for studying the effectiveness of home-based management of SAM children in the community.

Application of PHEL 'public health epidemiological logic' of public health intervention and public health impact

There is a growing tendency where medicalization of public health through mass therapeutics and secondary preventive measures are being substituted for primary preventive activity. Scaled up mass therapeutic intervention in the community is being confused with public health intervention. The objective of this paper is to provide a broad public health and epidemiological criteria for public health intervention and public health impact

Colonization of mycoplasma in the upper respiratory tract of AIDS patients with pulmonary symptoms in Chennai, India.

BACKGROUND & OBJECTIVE: Mycoplasmas have been implicated in causing minor to severe respiratory infections in man. Mycoplasmas are considered to act as cofactors in patients with AIDS. A preliminary study was conducted to isolate mycoplasmas from sputum specimens of AIDS patients and non-HIV patients with underlying pulmonary symptoms and signs. METHODS: A total of 130 sputum samples (100 from AIDS patients and 30 from non-HIV) were cultured on standard pleuropneumonia-like organisms (PPLO) glucose agar up to 3 wk. The plates were examined for the presence of fried-egg colonies characteristic of Mycoplasma. Subsequently the plates were stained using Diene's stain. Sputum specimens from the AIDS patients were also screened for other bacterial pathogens. RESULTS: Mycoplasmas were detected from 36 (36%) of the AIDS patients and only 5 (16.6%) of the non HIV control individuals with underlying pulmonary symptoms. Data on the detection rates of other microorganisms from the AIDS cases were also analysed. INTERPRETATION & CONCLUSION: This preliminary study provided supportive evidence that mycoplasma colonized in upper respiratory tract of individuals with AIDS to a larger extent than that of the non HIV subjects with pulmonary symptoms. Further studies need to be done to characterize mycoplasma isolates to species level.

Pituitary gonadotropins regulate spermatogonial differentiation and proliferation in the rat.

The relative regulatory roles of the pituitary gonadotropins, luteinizing hormone and follicle stimulating hormone in the spermatogonial proliferation has been studied using specific antibodies against these hormones in the immature rats. Immunoneutralization of luteinizing hormone for 7 days resulted in significant reduction in tetraploid cells and total absence of haploid cells, while there was a relative increase in the diploid population. This was also accomopanied by a decrease in spermatogonial proliferation as indicated by a decrease in [3H] thymidine incorporation into DNA by purified spermatogonia. Administration of follicle stimulating hormone a/s for 7 days also caused a significant decrease in the rate of spermatogonial proliferation. Withdrawal of follicle stimulating hormone led to a significant reduction in tetraploid and haploid cells. However interestingly, it failed to totally abolish the appearance of these cells. Administration of testosterone (3 mg/day/rat) for 2 days along with the gonadotropin a/s could partially reverse the effect on spermatogonial proliferation. It is concluded that (i) both luteinizing hormone and follicle stimulating hormone are involved in spermatogonial proliferation, (ii) lack of testosterone consequent of the neutralization of luteinizing hormone prevented the entry of spermatogonial cells into meiosis, (iii) testosterone may be involved in spermatogonia] proliferation providing a mitotic signal and (v) both follicle stimulating hormone and testosterone act synergistically and lack of any one of the hormones results in impairment of spermatogonial proliferation.

Enlarging pulmonary histoplasmoma associated with pulmonary tuberculosis.

Histoplasmosis is not a frequently reported infection from India. Similarity of its clinical and radiological features with pulmonary tuberculosis, may cause a difficult diagnostic dilemma when the two occur together. We report a case who initially presented with cavitary lesions over right lung responding well to anti tuberculosis chemotherapy but subsequently a small opacity present over the left upper zone showed a relentless increase till it attained a massive size few years later. Operative removal and histopathological examination of the mass confirmed it to be histoplasmoma. She became sputum AFB smear positive and culture negative for a short while during this period and this is explained on the basis of previous reports.

Mechanism of down regulation of luteinizing hormone receptors and steroidogenesis in corpora lutea.

The mechanism of ‘down regulation’ of luteinizing hormone receptors was investigated in pseudopregnant rats using a modified radioimmunoassay capable of measuring endogenous tissue-bound hormone. Treatment of pseudopregnant animals with a desensitizing dose (desensitization treatment) of human chorionic gonadotropin resulted in a decrease in receptor concentration. This decrease was prevented if the animals were treated prior to the desensitization treatment with indomethacin, an inhibitor of prostaglandin biosynthesis, suggesting a role for prostaglandins in down regulation. The desensitization treatment resulted in a time-dependent decrease in subsequent responsiveness of the tissue to luteinizing hormone. Basal progesterone production rate was also decreased following desensitization. Total tissue cholesterol was found to be decreased following desensitization treatment, without any change in the ratio of free to esterified cholesterol. Mitochondrial cholesterol was significantly reduced and pregnenolone production by the mitochondria of desensitized corpora lutea was also markedly reduced. However, when cholesterol was added to the mitochondria of desensitized corpora lutea, pregnenolone production was increased, reaching values almost equal to that shown by the control mitochondria. These results show that decrease in the responsiveness following desensitization treatment is due to, besides receptor loss, decrease in tissue cholesterol, in particular mitochondrial cholesterol. The cholesterol side chain cleavage activity, although low, appears to be functionally intact; the low activity could be attributed to low levels of mitochondrial cholesterol.
