Background:
The “second wave” of the COVID-19 pandemic hit India from early April 2021 to June 2021. We describe the clinical features, treatment trends, and baseline laboratory parameters of a cohort of patients with SARS-CoV-2 infection and their association with the outcome.

Methods:
This was a retrospective cohort study. Multivariate logistic regression models were fitted to identify clinical and biochemical predictors of developing hypoxia, deterioration during the hospital stay, and death.

Results:
A total of 2080 patients were included. The case fatality rate was 19.5%. Among the survivors, the median duration of hospital stay was 8 (5–11) days. Out of 853 (42.3%%) of patients who had COVID-19 acute respiratory distress syndrome at presentation, 340 (39.9%) died. Patients aged >45 years had higher odds of death as compared to the 18–44 years age group. Vaccination reduced the odds of death by 40% (odds ratio [OR] [95% confidence interval [CI]]: 0.6 [0.4–0.9], P = 0.032). Patients with hyper inflammation at baseline as suggested by leukocytosis (OR [95% CI]: 2.1 [1.5–3.1], P < 0.001), raised d-dimer >500 mg/dL (OR [95% CI]: 3.2 [2.2–4.7], P < 0.001), and raised C-reactive peptide >0.5 mg/L (OR [95% CI]: 3.7 [2.2–13], P = 0.037) had higher odds of death. Patients who were admitted in the 2nd week had lower odds and those admitted in the 3rd week had higher odds of death.

Conclusion:
This study shows that vaccination status and early admission during the inflammatory phase can change the course of illness of these patients. Improving vaccination rates and early admission of patients with moderate and severe COVID-19 can improve the outcomes.

Introduction:
Sarcoidosis is a multisystem granulomatous disease with a varied clinical presentation. We describe the clinical characteristics of patients with sarcoidosis from a tuberculosis (TB) endemic setting.

Methods:
We performed an analysis of the sarcoidosis database at a tertiary care facility in North India.

Results:
Of the 327 patients, 50.8% were male, with a mean age of 42.8 years (range: 16–70 years). Females were significantly older. 42.6% had comorbidities, of which diabetes (17.1%) was most common. More than half (57.1%) were obese. Serum angiotensin-converting enzyme levels were elevated in 186 (57.9%). Eleven (3.8%) had hypercalcemia, while hypercalciuria was present in 54 (31.7%). The majority (89.9%) were tuberculin skin test negative (<10 mm induration), while 71.9% were tuberculin anergic. 47.7% had normal spirometry, while a restrictive impairment was the most common abnormality (44.6%). Obstruction on spirometry was present in 8.3%. Nearly half (160, 49%) had involvement of an extrapulmonary site. Most patients were (96%) symptomatic. Cough, shortness of breath, fatigue, weight loss, and fever were the predominant symptoms. A majority had Stage 1 (47.7%) sarcoidosis. Two hundred and eighty-seven (87.8%) patients underwent bronchoscopy or endosonographic (endobronchial ultrasound-guided transbronchial needle aspiration [EBUS-TBNA] or transesophageal bronchoscopic ultrasound-guided fine-needle aspiration [EUS-B-FNA]) sampling. A histopathological diagnosis with the demonstration of granulomas was achieved in 90.8%. The diagnostic yield of EBUS-TBNA/EUS-B-FNA was 77.4%. In 13.5% of patients, necrotizing granulomas were present in tissue samples.

Conclusion:
The clinical profile of patients with sarcoidosis in TB endemic settings has certain differences from nonendemic populations. Bronchoscopy and endosonography allow a confident diagnosis in the majority of patients.
Effects of Tonal Noise on Workers’ Annoyance and Performance
Authors: Radosz Jan 
Published: December 2021

Objective:
Numerous references indicate that the subjectively assessed tonal noise annoyance is higher than that of broadband noise. There are no criteria for the impact of tonal noise in assessing the occupational environment for both indoor areas and workplaces.

Materials and Methods:
The study participants included 50 people who met the audiometric qualification criteria. The research method employed both a questionnaire survey and computer psychological tests checking work performance, attention level, and memory. Four types of generated test signals were developed (filtered noise − A and three signals with tonal components 125, 1600, and 8000 Hz − B, C, and D) at the same sound level A of 55 dB. Test signals C and D were assessed as causing the greatest annoyance and as the loudest.

Results:
The results of some tests and the assessment of annoyance and of the volume of test signals containing medium and high frequency tonal components were correlated with the participants’ noise sensitivity, determined on the basis of a questionnaire. Although there are no statistically significant differences, it was observed in most cases for signals with C (1600 Hz) and D (8000 Hz) tonal components that the results (mean values or median values) of psychological tests deteriorated with respect to a noise signal without tonal components (A) − a smaller number of calculations, a smaller number of correct responses, more errors made.

Conclusion:
These results, combined with those of the questionnaire survey, justify the introduction of the tonality annoyance criterion for workstations where, among other things, focusing one’s attention is required.

MANAGING THE POROUS BOUNDARIES: IMPACT OF WORKING FROM HOME ON WORK LIFE BALANCE OF UNIVERSITY TEACHERS DURING COVID 19

Published: December 2021

The closure of educational institutions due to COVID-19 has forced universities to shift from in-class to online education. We aim to address an aspect of this shift that remains widely unacknowledged, namely, the gender inequalities associated with the struggle to manage two separate domains (home and work) under the same roof. Using cross sectional data gathered through an online survey from various universities and degree awarding institutions, we explore the question of how working from home during the covid-19 pandemic has shifted (or not shifted) the work-life balance of male and female university teachers. Our research shows that work from home during covid-19 has some negative repercussions for the work life balance of female university teachers. Females are facing difficulty in maintaining a healthy work life balance. They reported more work family conflicts; more family demands and challenges; and less satisfaction while working from home as compared to male university teachers. The findings of our paper suggest that this new workplace arrangement has disproportionately increased the overall burden on female university teachers in both the important domains of their life (Family and work).

The relationship of the anterior inferior cerebellar artery diameter and the vascular loop type with the clinical manifestations in vascular loop syndrome: a clinical radiologic study
Authors: ÇANKAL Fatih 
Published: December 2021

Objective: Tinnitus and vertigo are common audiovestibular symptoms in the population. Many diseases can lead to the appearance of these symptoms, but the exact cause can often not be determined. It has been suggested that compression of the cranial nerves by vascular structures may be the cause of various clinical manifestations. This is known as microvascular compression syndrome. Some studies have stated that vascular compression syndromes are a serious pathology, while many studies have argued that vascular compression is only a radiological finding. We aimed to contribute to the literature on vascular compression syndrome and vascular loop types, which is still a controversial topic, and to determine the location of the diameter change in the anterior inferior cerebellar artery in the compression syndrome.
Material and Method: Patients who underwent a Magnetic Resonance Imaging (MRI) examination of Temporal Bone due to a complaint of tinnitus or vertigo were retrospectively examined. The complaints of the patients, the diameters of the anterior inferior cerebellar artery (AICA) and the types of vascular loop were evaluated in the high resolution 3D fast imaging employing steady-state acquisition (FIESTA) sequence, according to the CHAVDA classification. The statistical relationship between the age of the patients, anterior inferior cerebellar artery diameters and vascular loop types and their clinical manifestations was investigated.
Results: A total of 52 patients were enrolled in the study, of which 28 (53.8%) were male and 24 (46.2%) were female. The mean age of all patients was 47.58±18.734 years. The mean right AICA diameters of the patients were 1.10±0.206 mm, the mean left AICA diameter was 1.11±0.253 mm. Type 1 in 29 patients, type 2 in 12 patients, type 3 vascular loop in 4 patients were observed for the right side, while type 1 in 29 patient, type 2 in 12 patients, and type 3 in 7 patients were observed for the left side. There was no significant difference between vascular loop and tinnitus on the right and left (p=0.705; p=0.335, respectively). There was no significant difference between the right vascular loop and the left vascular loop and the vertigo (p>0.999; p=0.425, respectively). There was no significant difference between the right tinnitus, left tinnitus and vertigo in terms of the diameters of the right and left AICA in the patients (p=0.782; p=0.762; p=0.408; p=0.915, respectively).
Conclusion: Vascular compression syndromes are clinical conditions that show symptoms over cranial nerves. Although the vascular loop syndromes originating from AICA have been discussed a lot recently, it is seen that there is no definite opinion. In our study, no association of AICA diameter and vascular loop type with clinical findings was found.
Technical Note: Effect of High-Current Pulsed Electron Beam Processing of Zr-1%Nb Alloy on Its Oxidation Kinetics at 1,200°C in Air and Steam

Published: December 2021

The paper reports the effect of high-current pulsed electron beam (HCPEB) processing of the Zr-1%Nb alloy as one of the most widely used in water-cooled nuclear reactors, based on the kinetics of its oxidation at 1,200°C in air and steam (these conditions are typical for potential loss-of-coolant accidents). It was shown that HCPEB processing caused a change in the surface morphology of the samples. In particular, craters with diameters of about 100 μm were found on the modified surfaces. They had initiated at an energy density of 5 J/cm2 and were characterized by relevant reliefs with microcracks. After HCPEB processing at 10 J/cm2, the craters were deeper with fractured surface layers. In addition, a pronounced surface relief corresponding to quenched martensitic microstructures was observed on the modified sample surfaces that had formed due to high heating and cooling rates. Due to sufficient degradation of the sample surfaces after HCPEB processing at 10 J/cm2, the kinetics of high-temperature oxidation was estimated only for the as-received samples and ones treated at 5 J/cm2. It was found that the as-received samples showed slightly greater weight gain levels in both air and steam environments, which fully correlated with the thickness ratio of the oxide, α-Zr(O), and prior-β layers. These phenomena and further research directions were discussed.

The characteristics of microplasma discharge propagation over
the titanium surface covered with a thin oxide film

Published: December 2021

The propagation and structure of a microplasma discharge initiated in vacuum by a pulsed plasma flow with a density of 1013 cm–3 on the surface of a titanium sample covered with a
thin continuous dielectric titanium oxide film with a shickness of 2–6 nm were studied experimentally when the electric current of the discharge changes from 50 A to 400 A.
It was found that the microplasma discharge glow visually at the macroscale has a branched structure of the dendrite type, which at the microscale consists of a large number
of brightly glowing “point” formations – cathode spots localized on the metal surface. The resulting erosion structure on the titanium surface is visually “identical” to the structure of
the discharge glow and consists of a large number of separate non-overlapping microcraters with characteristic sizes from 0.1–3 μm, which are formed at the sites of localization of
cathode spots at distances of up to 20 μm from each other. It was found that the propagation of a single microplasma discharge over the titanium surface covered with a thin oxide film a
thickness of 2–6 nm occurs at an average velocity of 15–70 m/s when the amplitude of the discharge electric current changes in the range of 50–400 A. In this case, the microplasma
discharge propagation on the microscale has a “jumping” character: the plasma of “motionless” burning cathode spots, during their lifetime 1 μs, initiates the excitation of new
microdischarges, which create new cathode spots at localization distances of 1–20 μm from the primary cathode spots. This process repeated many times during a microplasma dis-
charge pulse with a duration from 0.1 ms to 20 ms.

Published: December 2021

The possibilities of technological ensuring of the uniformity of thickness distribution of a thin-film metal coating produced by magnetron sputtering on the inner surface of a thinwalled silica resonator made in the shape of a hemisphere are considered. The possibility of minimizing the thickness of the coating by optimizing the diameter of the annular magnetron emission zone in combination with the distance from the resonator to the target made of sprayed material is shown. A further increase in the evenness of thickness of the coating
is possible on the basis of the use of a fixed screen with a hole, the shape and location of which are calculated analytically, and the final configuration of the contour is specified empirically
Clinical Verification of Homeopathy
Authors: Wassenhoven Michel Van 
Published: December 2021

The world is changing! This is certainly true regarding the homeopathic practice and access to homeopathic medicine. Therefore our first priority at the ECH-LMHI [1] has been to produce a yearly report on the scientific framework of homeopathy. In the 2010 version a new chapter about epidemic diseases has been added including the Leptospirosis survey on the Cuban population. A second priority has been to review the definition of the homeopathic medicines respecting the new framework generated by the official registration procedure and the WHO report. We are working now on a documented (Materia Medica and provings) list of homeopathic remedies to facilitate the registration of our remedies.
The new challenges are: first of all more good research proposals and as such more funding (possible through ISCHI + Blackie Foundation as examples) [2]; international acceptance of new guidelines for proving and clinical verification of homeopathic symptoms (Proposals are ready for discussion); total reconsideration of the homeopathic repertories including results of the clinical verification of the symptoms.
The world is changing, we are part of the world and changes are needed also for homeopathy!
