The Impact of COVID-19 on Distress Tolerance in Pakistani Men and Women.

The novel coronavirus (COVID-19) is an infectious disease that spread across the world, bringing with it serious mental health problems for men and women. Women in Pakistan are infected with COVID-19 at a much lower rate than men, yet report worse mental health. To explain this paradox, we surveyed 190 participants (46% male) shortly following the country lockdown, focusing on perceptions of the COVID-19 impact and positive adjustment. Measures used in this study included the Warwick-Edinburgh Mental Well-being Scale and Distress Tolerance Scale. Factor analysis revealed five distinct areas related to COVID-19, which did not differ by sex. However, men reported higher levels of both distress tolerance and well-being than women. High endorsement of actions to protect against COVID-19 was related to lower distress tolerance scores, but in different ways for men and women. Men, but not women, who endorsed more protective measures to stop the pandemic reported higher DTS absorption scores, and therefore being more consumed by distress; women who endorsed more protective measures to stop the pandemic reported less acceptance of distress than men, as reflected in DTS appraisal scores. An in-depth analysis of women's beliefs and behaviors related to COVID-19 is warranted to understand why Pakistani women who are infected with COVID-19 at lower rates than men show more mental health symptoms.

Cultural Adaptation and Validation of the Urdu Version of the Cognitive Emotion Regulation Questionnaire (CERQ) in Male Patients With Substance Use Disorders (SUDs) in Pakistan.

Background: Adults with substance use disorders (SUDs) often have co-occurring mental health problems. Emotion regulation may play a vital role in mental health problems. The Cognitive Emotion Regulation Questionnaire (CERQ) is a widely used measure for assessing cognitive emotion regulation. However, it has not been used in Pakistan on patients with co-occurring SUDs and mental health issues. The present study aims to translate and adapt the CERQ into the Urdu language and to determine its reliability and convergent validity in a sample of male patients with SUDs in Pakistan. Method: Participants completed a demographic information form, the CERQ, the Depression, Anxiety, and Stress Scale Short Form [DASS-21)], and the Rosenberg Self-Esteem Scale [RSES)] in Urdu. Results: Male participants (N = 237) 18-50 years of age (M = 29.8, SD = 8.1) were recruited from four substance use disorder treatment centers and hospitals in Karachi. The reliability of the Urdu version of the CERQ was based on an examination of its internal consistency reliability (Cronbach's α) and test-retest reliability for both the total scale and its subscales. Internal consistency for the CERQ total (α = 0.80) was adequate, as it was for subscales of self-blame, (0.76) acceptance (0.78), rumination (0.72), positive refocusing (0.79), focus on planning (0.89), positive reappraisal (0.81), putting into perspective (0.83), catastrophizing (0.73), and other blame (0.70). The 10-14 day test-retest reliability of the CERQ total score was 0.86. Higher CERQ scores were significantly (ps < 0.001) negatively associated with DASS-21depression (r = -0.24), anxiety (r = -0.23), and stress (r = -0.27) subscales, as well as the DASS-21 total score (r = -0.26) and positively associated with the RSES self-esteem score (r = 0.30). Conclusion: The Urdu version of the CERQ is a reliable measure for investigating cognitive emotion regulation strategies related to mental health and SUDs in Pakistan.

Synthesis of (4R)-thiazolidine carboxylic acid and evaluation of antioxidant potential.

We report here the synthesis as well as antioxidant activity of a series of 2-aryl thiazolidine-4-carboxylic acids, including two novel derivatives. They were synthesized by nucleophilic cyclic condensation of L-cysteine hydrochloride with a range of aromatic aldehydes. Their in vitro antioxidant activity was evaluated by DPPH radical scavenging assay. It was observed that the aromatic substituent at C-2 of thiazolidine ring effects the antioxidant potential of the thiazolidine derivatives. The nature and position of the substituents on aromatic ring were correlated with antioxidant activity. Compounds with -OCH3 group on aromatic ring showed a better radical scavenging property than the other groups such as -Cl, -F, and -NO2. The presence of phenyl ring thus enhanced radical scavenging activity.

Different risk factors are associated with alcohol use versus problematic use in male Pakistani adolescents.

Substance abuse is a significant problem in Pakistan (Hussain, 2017), yet, there are few studies of risk factors in this population, particularly in remote areas. Male adolescents (N = 243; M = 16.9 years, SD = 1.3 years) were recruited from schools in Gilgit-Baltistan, and completed questions on demographics, substance use, and psychosocial functioning. As a Muslim country, there are strict prohibitions against alcohol use, yet 44.9% of the sample reported lifetime alcohol use. The Alcohol Use Disorders Identification Test (Babor, Higgins-Biddle, Saunders, & Monteiro, 2001), was used to quantify level of risk associated with use, and 22.6% of the sample had scores indicating significant risk levels. Logistic regression analyses indicated that lifetime alcohol use was associated with internalising problems (e.g., depression, anxiety), while risky alcohol use was associated with externalising problems (e.g., aggressive and delinquent behaviour). Attention problems were related to both outcomes. Implications for prevention are discussed.

Validation of rapid neurodevelopmental assessment instrument for under-two-year-old children in Bangladesh.

OBJECTIVE: The objective of this study was to determine the reliability and validity of a comprehensive assessment procedure for ascertaining neurodevelopmental status of children aged 0 to 24 months for use by multidisciplinary professionals in a developing country. METHODS: We developed the Rapid Neurodevelopmental Assessment (RNDA) to determine functional status in the following domains: primitive reflexes, gross motor, fine motor, vision, hearing, speech, cognition, behavior, and seizures. Reliability was determined for 50 children who were aged <3 months and 30 children who were aged > or =3 to 24 months and were administered the RNDA by 8 different professionals (3 physicians, 4 therapists, and 1 special teacher). Validity was determined on 34 children aged <3 months in hospital and 81 children aged > or =3 to 24 months in urban (n = 47) and rural (n = 34) community-based populations by any 1 of the 8 professionals, with simultaneous administration of the adapted Bayley Scales of Infant Development II by a psychologist as the gold standard. RESULTS: Mean kappa coefficients of agreement among professionals in overall and individual domains in the 2 age groups ranged from good to excellent. For both younger and older children, there was good concurrent validity (ie, significantly lower mean Mental Development Index and Psychomotor Development Index scores) for children with > or =1 neurodevelopmental impairment and for children with impairments in most functional domains, compared with children with no impairments. Significantly more impairments were found in children from disadvantaged compared with socioeconomically more advantaged communities, indicating good discriminant validity. CONCLUSIONS: The RNDA can be used by professionals from a range of backgrounds with high reliability and validity for determining functional status of children who are younger than 2 years. The study findings have important practical implications for early identification and intervention to mitigate neurodevelopmental impairments in large populations that live in developing countries where professional expertise is sparse.

Probing the pharmacophore of ginkgolides as glycine receptor antagonists.

Ginkgolides are antagonists of the inhibitory ligand-gated ion channels for the neurotransmitters glycine and gamma-aminobutyric acid (GABA). In this study the ginkgolide structure was modified in order to investigate the minimum structural requirements for glycine receptor antagonism. The five native ginkgolides and a series of 29 ginkgolide derivatives were characterized at the three glycine receptor subtypes alpha1, alpha1beta, and alpha2, which revealed that only minor changes in the ginkgolide skeleton were allowed for maintaining glycine receptor antagonism. A pharmacophore model was generated and applied in a virtual screening of a compound database (300000 compounds), resulting in the identification of 31 hits. Twenty-seven of these hits were screened for biological activity, but none displayed antagonist activity at the glycine receptors. This strongly suggests the importance of other pharmacophore components in the binding of ginkgolides to glycine receptors, and we propose that the structural rigidity of the ginkgolide molecule may be crucial for its glycine receptor activity.

Neurodevelopmental outcomes of preterm infants in Bangladesh.

OBJECTIVES: The purpose of this work was to determine neurodevelopmental outcomes of preterm infants followed by a multidisciplinary team in a tertiary hospital in Bangladesh. METHODS: Infants <33 weeks' gestational age were serially assessed for neurodevelopment by physicians and developmental psychologists. An estimate of "low," "moderate," or "high" risk for neurodevelopmental impairments was made at the first visit. At later assessments, neurodevelopmental impairments were graded by severity as "none," "mild," or "serious." RESULTS: Of the 159 enrolled children, 65% survived, 16% died, and 19% were lost to follow-up. Family income was lowest among those who died, and maternal and paternal literacy was highest among the survivors. At a mean age of 31 months, developmental status of the 85 children followed-up for > or = 12 months was normal in 32%; 45% had mild and 23% had serious neurodevelopmental impairments. Cognitive impairment was the most common deficit (60%). Final outcome was significantly better than estimated initially. Most serious (85%) but fewer mild (37%) problems were identified independently by both child health physicians and psychologists. CONCLUSIONS: Parental education and family income had significant influence on postdischarge mortality. Two thirds of infants demonstrated neurodevelopmental impairments. Most mild cognitive impairments would have been missed had either physicians or psychologists alone done the assessments. Preterm infants in this low-resource setting are at high risk for neurodevelopmental impairments, which need to be identified early, preferably by a multidisciplinary team of professionals.
