Abstract
The evolution of magnetism in late-type dwarfs remains murky, as we can only weakly predict levels of activity for M dwarfs of a given mass and age. We report results from our spectroscopic survey of M dwarfs in the Southern Continuous Viewing Zone (CVZ) of the Transiting Exoplanet Survey Satellite (TESS). As the TESS CVZs overlap with those of the James Webb Space Telescope, our targets constitute a legacy sample for studies of nearby M dwarfs. For 122 stars, we obtained at least one R ≈ 2000 optical spectrum with which we measure chromospheric Hα emission, a proxy for magnetic field strength. The fraction of active stars is consistent with what is expected for field M dwarfs; as in previous studies, we find that late-type M dwarfs remain active for longer than their early-type counterparts. While the TESS light curves for ≈20% of our targets show modulations consistent with rotation, TESS systematics are not well enough understood for confident measurements of rotation periods (P
rot) longer than half the length of an observing sector. We report periods for 12 stars for which we measure P
rot ≲ 15 days or find confirmation for the TESS-derived P
rot in the literature. Our sample of 21 P
rot, which includes periods from the literature, is consistent with our targets being spun-down field stars. Finally, we examine the Hα-to-bolometric luminosity distribution for our sample. Two stars are rotating fast enough to be magnetically saturated, but are not, hinting at the possibility that fast rotators may appear inactive in Hα.
The Appearance of Vortices in Protoplanetary Disks in Near-infrared Scattered Light
Authors: Marr Metea , Dong 董 Ruobing 若冰 
Published: May 2022

Abstract
Azimuthally asymmetric structures have been discovered in millimeter continuum emission from many protoplanetary disks. One hypothesis is that they are vortices produced by the Rossby wave instability, for example at the edges of planet-opened gaps or dead zones. Confirming the vortex nature of these structures will have profound implications to planet formation. One way to test the hypothesis is to compare the observed morphology of vortex candidates in near-infrared scattered light with theoretical expectations. To this end, we synthesize the appearance of vortices in H-band polarized light by combining hydrodynamic and radiative transfer simulations of the Rossby wave instability at a dead-zone edge. In a disk at 140 pc, at the peak in its evolution a vortex at 65 au may appear as a radially narrow arc 50%–70% brighter compared with an axisymmetric disk model. The contrast depends on the inclination of the disk and the position angle of the vortex only weakly. Such contrast levels are well detectable in imaging observations of bright disks using instruments such as the Very Large Telescope/SPHERE, Subaru/SCExAO, and Gemini/GPI. A vortex also casts a shadow in the outer disk, which may aid its identification. Finally, at modest-to-high inclinations (e.g., 60°) a vortex may mimic a one-armed spiral. In the HD 34282 disk, such a one-armed spiral with a shadowed region on the outside has been found in scattered light. This feature roughly coincides with an azimuthal asymmetry in millimeter continuum emission, signifying the presence of a vortex.
Description of Perithreticus neglectus sp. n. from the West Usambara Mountains, Tanzania (Diptera, Psychodidae)
Authors: Kvifte Gunnar 
Published: May 2022

The Psychodinae of the Afrotropical Region remain poorly understood. Slightly under 200 species have been described, but many countries have received very little attention from collectors and even countries where significant collection efforts have taken place have rarely had their collections studied in detail by specialist taxonomists.Perithreticus neglectussp. n. is described from the West Usambara Mountains, Tanzania, based on a male specimen collected in 1990. The new species is similar toPerithreticus anderseniKvifte, 2015, which occurs in the same forest reserve, but can be separated by several genitalic characters, including the hypandrium well-developed with sclerotised anterior and posterior margins, gonocoxites narrower, the gonostyles with the slender apex shorter, the parameres shorter without pronounced basolateral projections and the surstylus with slightly fewer tenacula. The world fauna ofPerithreticusnow comprises five described species, of which two occur in the Afrotropical Region.

Background:
The Radboud Oral Motor Inventory for Parkinson's disease (ROMP) is a patient-rated assessment measuring patients' perceptions of speech, swallowing, and saliva control among patients with idiopathic Parkinson's disease (IPD).

Objective:
The present study was carried out to adapt and validate the Sinhala version of the ROMP questionnaire in a Sinhala-speaking patient cohort diagnosed with IPD.

Materials and Methods:
The study population consisted of patients diagnosed with IPD attending a tertiary care neurology clinic at the National Hospital of Sri Lanka. ROMP was translated from English to Sinhala, and an expert committee verified its content. Construct validity was assessed by correlating the Sinhala ROMP scores with the subscales in speech, salivation, and swallowing of the Unified Parkinson's Disease Rating Scale and with five-point Likert-type scale to assess dysarthria, dysphagia, and drooling by a speech and language therapist. Test–retest reproducibility was assessed by repeating the questionnaire in 2 weeks.

Results:
A cohort of 21 patients was evaluated (male to female ratio = 2.5:1, mean age was 58.8 [±8.3] years). The Spearman's correlations between ROMP and the Likert-type scale assessment, that is, speech r = 0.85 (P < 0.01), swallowing r = 0.86 (P < 0.01), and drooling r = 0.88 (P < 0.01), and subscales of the UPDRS were statistically significant, that is, speech r = 0.75 (P < 0.01), swallowing r = 0.96 (P < 0.01), and salivation r = 0.94 (P < 0.01). Reproducibility of the three domains and total intraclass correlation coefficients indicated a high level of agreement in test–retest reproducibility (range: 0.98–0.99). The three subdomains of the instrument also had excellent internal consistency (total Cronbach's α = 0.99).

Conclusion:
The Sinhala version of ROMP has proved to be a good assessment tool for dysphagia, dysarthria, and drooling in the early stage of IPD patients.

Introduction:
The COVID-19 outbreak has created unpredictable stress physically and mentally in all sections of population. There is no exception for health-care workers being in frontline during this crisis period. Due to the virus rapid transmission and the pattern of clinical presentation, uncertainty, is created in the form of health emergency all over. There is a need to address mental health issues during this pandemic outbreak of COVID-19 in those who are in frontline.

Subjects and Methods:
It is an observational cross-sectional study performed in social health-care workers (accredited social health activist [ASHA]) to know the psychological disturbances during COVID-19 outbreak. This study has been done in primary health centers located in and around Karimnagar City, Telangana. The scale used to perform this study is Depression, Anxiety, and Stress Scale of 21 questions.

Results:
Out of 181 ASHA workers interviewed, majority of ASHA workers were at normal emotional states of depression (81.8%) and stress (91.2%), but about half (91, 50.3%) of them had moderate level of anxiety and 16 (9%) had severe anxiety level. Only 12 (6.6%) and 4 (2.2%) had moderate depression level, and stress level, respectively. Out of 91 ASHA workers who had moderate level of anxiety, only one had moderate level of depression and out of 16 who had severe level of anxiety, all of them had normal level of depression and stress.

Conclusion:
Frontline health care workers experience psychological disturbances during pandemics like COVID-19 to a certain degree. Administrators should be aware that the mental health support of health care workers is an important part of the COVID- 19 response. Educational interventions, to ensure understanding and use of infectious control measures. Psychological support, like counselling services and development of support systems among colleagues.

Published: May 2022

Background:Delirium is a neuropsychiatric disorder with a prevalence ranging from 16% to 53.6% in India. Although delirium is characterized as a unitary syndrome, not all symptoms follow the same trajectory over the course. Hence, there is a necessity for a larger number of studies to understand these phenomenological and etiological profiles across different regions in India.Aim:To study the clinico-etiological variables and phenomenological profile in delirium in the intensive care unit (ICU) setting.Materials and Methods:A longitudinal prospective study was conducted in a tertiary care hospital including all consecutive delirium patients who referred to the psychiatry department from ICU. All the participants' socioeconomic data were obtained and were administered. Charlson comorbidity index, Neelon and Champagne confusion scale, Richmond agitation sedation scale, delirium etiology checklist, delirium revised scale, revised-98, descriptive statistics, and ANOVA were used for statistical analysis.Results:Out of 51 study population, the mean age was 57.82 ± 17.19 years, with male preponderance and belonging to lower-middle and upper-lower class. 70.58% of the patients were found to have moderate–severe delirium. Majority of the referral population are from general medicine and of hyperactive delirium. There is no association established with the number of drugs and comorbidities with delirium severity. Metabolic disturbances are most common; sleep–wake cycle disturbance has the highest score and also the most common feature in delirium severity.Conclusion:Majority of the cases who were referred are male in moderate–severe stage and hyperactive delirium. As the detection of cases is challenging in the ICU settings, better understanding of the underlined etiological and phenomenological profiles may aid in easy identification of delirium cases at early stages.
A cross-sectional study of intimate partner violence, adverse childhood experiences, and psychiatric morbidity in females with mental illness at a tertiary hospital
Authors: Gour Sanchita , Rao Sireesha S 
Published: May 2022

Background:
Intimate partner violence (IPV) has an adverse effect on the mental health of women. Sparse literature is available on IPV in women with mental illness.

Aims and Objectives:
This study was carried out to assess the proportion of IPV, its correlation with sociodemographic factors, and its association with adverse childhood experiences.

Materials and Methods:
The study was cross-sectional. Convenient sampling technique was used to collect the sample. Remitted female patients were assessed on the Abuse Assessment screen and Adverse Childhood Experiences Scale. Semi-structured intake pro forma was used to enter sociodemographic details and diagnosis (as per International classification of diseases-10). Data were analyzed using SPSS V.22.

Results:
Proportion of IPV among female study subjects were found to be 67.14%. IPV was found to be more among subjects who were unmarried, single, divorced, those who had borderline, histrionic traits, and those whose partners were dependent on alcohol. IPV showed a positive correlation with adverse childhood experiences. Study subjects who showed more ACE showed a positive correlation with a family history of substance abuse, suicide attempts, and histrionic and borderline personality traits

Conclusion:
IPV was high among patients with mental illness. Risk is high if the partner has alcohol dependence syndrome. Marriage was found to be protective against IPV. Prevention and intervention programs and marital counseling should be directed toward the assessment and treatment of IPV among females with psychiatric disorders.
