Depression is one of the most frequently diagnosed psychiatric illnesses, which remains a big cause of mortality and morbidity among all groups of population. 1 Things are not different in our part of the world as depression remains a common mental health illness in our population. 2 If untreated, it may lead to serious consequences including severe depression with psychotic illness, physical problems and even suicide. [3][4][5] Transgender is a broad term which includes the people with all types of gender identity disorder. ICD-11 coins a new term for this group of people, i.e. gender incongruence. In United States of America, 390/100,000 individuals are believed to be transgenders. 6 Census of 2017 has shown that more than 10,000 transgender subjects exist in Pakistan. They suffer from various health issues including the HIV, drug dependence, and various mental health problems. 7,8 Previous research highlights the presence of depression and suicide ideation among the transgender population. Depression, suicide and other mental health indices are very high among the transgender population as compared to controls even in a developed country like USA. 9 Another study showed suicide attempt rate as 32-50% among the transgender population of our neighboring country India. This was also coupled with increased rate of depression among the target population. 10 Oswalt et al. concluded in a large study that all mental health illnesses including schizophrenia are found more among the transgender as compared to heterosexual controls. 11 Depression and suicidal ideation, if remain unaddressed for long, may result in poor life quality and even leading to death. 12 Suicidality and depression have some common biological pathways, which explain one of the bases of their comorbidity. Role of genetics, alteration in the hypothalamic-pituitary-adrenal (HPA) axis, dysregulation of serotonin metabolism and receptors and neuroimmunological basis are some of the factors which contribute in development of both depression and suicidality. 13 In addition to the biological factors, depression also leads to suicidal ideation and suicidality by psychological and social pathways. 14 Ideas of self harm are also part of diagnostic criteria for depression in

Introduction: The global burden of chronic airway diseases represents an important public health concern. The role of oxidative stress and inflammation in the pathogenesis of these diseases is well known. The aim of this study is to evaluate the behavior of both inflammatory and oxidative stress biomarkers in patients with chronic bronchitis, current asthma and past asthma in the frame of a population-based study. Methods: For this purpose, data collected from the Gene Environment Interactions in Respiratory Diseases (GEIRD) Study, an Italian multicentre, multicase-control study, was evaluated. Cases and controls were identified through a two-stage screening process of individuals aged 20-65 years from the general population. Out of 16,569 subjects selected from the general population in the first stage of the survey, 2259 participated in the clinical evaluation. Oxidative stress biomarkers such as 8-oxo-7,8-dihydro-2′-deoxyguanosine (8-oxodG), 8-isoprostane and glutathione and inflammatory biomarkers such as Fractional Exhaled Nitric Oxide (FENO) and white blood cells were evaluated in 1878 subjects. Results: Current asthmatics presented higher levels of FENO (23.05 ppm), leucocytes (6770 n/µL), basophils (30.75 n/µL) and eosinophils (177.80 n/µL), while subjects with chronic bronchitis showed higher levels of GSH (0.29 mg/mL) and lymphocytes (2101.6 n/µL). The multivariable multinomial logistic regression confirmed high levels of leucocytes (RRR = 1.33), basophils (RRR = 1.48), eosinophils (RRR = 2.39), lymphocytes (RRR = 1.26) and FENO (RRR = 1.42) in subjects with current asthma. Subjects with past asthma had a statistically significant higher level of eosinophils (RRR = 1.78) with respect to controls. Subjects with chronic bronchitis were characterized by increased levels of eosinophils (RRR = 2.15), lymphocytes (RRR = 1.58), GSH (RRR = 2.23) and 8-isoprostane (RRR = 1.23). Conclusion: In our study, current asthmatics show a greater expression of the inflammatory profile compared to subjects who have had asthma in the past and chronic bronchitis. On the other hand, chronic bronchitis subjects showed a higher rate of expression of oxidative stress biomarkers compared to asthmatic subjects. In particular, inflammatory markers such as circulating inflammatory cells and FENO seem to be more specific for current asthma, while oxidative stress biomarkers such as glutathione and 8-isoprostane appear to be more specific and applicable to patients with chronic bronchitis.

Abstract Aim: To assess the prevalence of depression among the transgender population and analyze the relationship of socio-demographic factors with depression. Study design: Cross-sectional study Place and duration of study: Twin cities (RWP and Islamabad). 3 months Subjects and Methods: The sample population comprised of one hundred and forty two transgender people of Rawalpindi and Islamabad. Beck depressive inventory II (BDI-II) was used to record the presence and severity of the depressive symptoms. Depressive symptoms were categorized as mild, moderate and severe. Relationship of the age, smoking, family income, illicit substance use and education was studied with the presence of depressive symptoms among these transgender population of twin cities of Pakistan. Results: A total of 142 transgender people were included in the final analysis. Mean age of the study participants was 39.55 ± 6.18. Out of these, 45.1% had no depressive symptoms while 31.7% had mild, 12.7% had moderate and 10.6% had severe depressive symptomatology. After applying the binary logistic regression we found that presence of depressive symptoms had significant association with illicit substance use among the target population. Conclusion: This study showed a high prevalence of depressive symptoms among the transgender population of twin cities of Pakistan. Use of illicit substances like tobacco, cannabis, opiates and alcohol should be discouraged and those using these should be routinely screened for the presence of other mental health issues in order to timely diagnose and treat them.   Key words: depression; socio-demographic factors; trans-genders
