Abstract
In this work, a novel silver nanoparticles-doped synthetic sodalitic composite was synthesized and characterized using advanced characterization methods, namely TEM-EDS, XRD, SEM, XRF, BET, zeta potential, and particle size analysis. The synthesized nanocomposite was used for the removal of Hg2+ from 10 ppm aqueous solutions of initial pH equal to 2. The results showed that the sodalitic nanocomposites removed up to 98.65% of Hg2+, which is ∼16% and 70% higher than the removal achieved by sodalite and parent coal fly ash, respectively. The findings revealed that the Hg2+ removal mechanism is a multifaceted mechanism that predominantly involves adsorption, precipitation and Hg-Ag amalgamation. The study of the anions effect (Cl-, NO3-, C2H3O2-, and SO42-) indicated that the Hg2+ uptake is comparatively higher when Cl- anions co-exist with Hg2+ in the solution.

Abstract
More than one-third of the world's population resides in Asia. China and India have the largest population densities and the focus of this article is on these two countries. In the seventeenth century, women were globally treated as inferior and subordinate to men. Women had to listen to their fathers, husbands, and sons, and they could not inherit business or wealth. Starting in the eighteenth century and continuing in the nineteenth century, women's rights became central to political debates in Europe which demanded human rights, leading to the Women's Rights Movement. The Feminist movement began in the twentieth century, which focused on the reproductive rights of women. In the twentieth century, various Declarations have been signed by the United Nations to offer both gender equity and equality to women in the world, but unfortunately many of them have not been put into practice in Asia. In the twenty-first century, the feminist movement is focusing more on women having the power to decide the course of their lives. We still have to overcome challenges of unequal economic opportunity, political empowerment, gender violence, and human trafficking to achieve gender equality in Asia.

Abstract
Aims and Objectives: This study aimed to compare the vitamin D levels between chronic obstructive pulmonary disease (COPD) patients and healthy controls and to describe the correlation between vitamin D levels and lung functions. Methods: Fifty COPD patients (cases) and 30 healthy volunteers (controls) were recruited and their serum vitamin D level was measured together with lung function (forced vital capacity and forced expiratory volume in 1 s [FEV1]) by spirometry. vitamin D was categorized as ≤20 nmol/l: deficient, 21–50 nmol/l: inadequate, and ≥51 nmol/l as sufficient. Results: In this case–control cross-sectional study, lower vitamin D levels were associated with lower lung function in both cases as well as controls, the effect being more pronounced in cases. Mean FEV1 at vitamin D ≤20 nmol/l (0.98 ± 0.40 vs. controls 1.93 ± 0.24 with P = 0.006), mean FEV1 at vitamin D 21–50 nmol/l (1.55 ± 0.54 vs. 2.20 ± 0.31 with P = 0.000), and mean FEV1 at vitamin D ≥51 nmol/l (2.06 ± 0.54 vs. 2.20 ± 0.31 with P = 0.002). Moreover, the severity of predicted postbronchodilator FEV1% was also much lower among COPD cohort versus healthy volunteers (mean FEV1%: cases 47.88 ± 14.22 vs. controls 58.76 ± 15.05 with P = 0.002). Conclusions: Importantly, lung function in both the groups was affected by decreased vitamin D level; decrease in FEV1 was more pronounced among COPD patients compared to controls showing more expiratory airflow limitation. Vitamin D levels are associated with changes in lung function in cases of COPD as well as healthy controls. Larger studies to confirm the association in Indian context are required and routine assessment of vitamin D may be undertaken to obviate the effects of low vitmain D level on lung function.

Abstract
AIMS To assess the prevalence of risk factors for obstructive sleep apnoea in people with diabetic foot ulcers and to determine whether this risk predicts diabetic foot ulcer healing. METHODS We studied 94 consecutive people (69% men) with diabetic foot ulcers (Type 2 diabetes, n=66, Type 1 diabetes, n=28) attending a university hospital foot unit. All participants were screened for obstructive sleep apnoea using the STOP-BANG questionnaire, with a score ≥4 identifying high risk of obstructive sleep apnoea. The primary outcome was poor diabetic foot ulcer healing, defined as diabetic foot ulcer recurrence (diabetic foot ulcers which healed and re-ulcerated in same anatomical position) and/or diabetic foot ulcer persistence (no evidence of healing on clinical examination). All participants were evaluated at 12 months. RESULTS Of the 94 participants, 60 (64%) had a STOP-BANG score ≥4. Over 12 months, 27 participants with a score ≥4 had poor diabetic foot ulcer healing as compared to seven with a score <4 (45% vs 20.5%; P=0.025). A STOP-BANG score ≥4 significantly increased the relative risk of poor healing more than twofold, independently of other risk factors in multivariable analyses. CONCLUSIONS There is a high prevalence of features and risk of obstructive sleep apnoea in people with diabetic foot ulcers. A STOP-BANG score ≥4 predicts poor diabetic foot ulcer healing. Obstructive sleep apnoea may be a potential, modifiable risk factor/treatment target to improve diabetic foot ulcer outcomes.

Abstract
Choroidal nevi are benign fundus lesions that require regular follow with documentation. Conventional color fundus photography (CFP) has traditionally been used to images these lesions. Multicolor imaging (MCI) available on Spectralis spectral domain optical coherence tomography system is increasingly been tested vis-à-vis conventional CFP in various retinal diseases. We present data of the right eye of a 59-year-old gentleman with choroidal nevus who underwent conventional CFP as well as MCI. Nevus appeared orange red on MCI and its size appeared larger than the same measured on conventional CFP. We also report infrared reflectance and near infrared autofluorescence features of choroidal nevus.

Abstract
Acute zonal occult outer retinopathy (AZOOR) is a retinal disease characterized by a slow onset loss of retinal function with minimally evident fundus changes. Patients with AZOOR present with initially progressive scotoma and photopsia. Its pathogenesis has not been definitively determined as of yet. Characteristically, the extent of the visual field defect is unexplained by fundus examination, but there is marked retinal dysfunction, which is evident on multimodal imaging and electrophysiological testing. We herein describe multimodal imaging signatures of AZOOR, in a patient of Indian origin, highlighting the hitherto unreported multicolor channels and near-infrared autofluorescence.

Abstract
Glaucoma is a progressive optic neuropathy associated with irreversible loss of retinal ganglion cells (RGC). This emblematic localized retinal nerve fiber layer defect (RNFLD) can be the earliest sign to detect the ongoing glaucomatous damage. Slitlamp biomicroscopy [90D & 78D], colour and redfree fundus photography, OCT & HRT are used conventionally for early detection of RNFLD. Multicolour Imaging (MCI) is a new non-invasive retinal imaging modality available in Spectralis platform which simultaneously acquires three reflectance images of the retina using three individual lasers producing a composite image thereby allowing analysis of changes at various levels within the retina. MCI provides sharper image, enables imaging through small pupil and hazy media. Current report describes 2 cases where in MCI proved superior to CFP and conventional redfree photograph in delineating area of RNFLD. This is the first report of MCI in RNFL imaging. The present report highlights the role of MCI in detection of RNFLD.

Abstract
Dengue fever, a mosquito-borne disease commonly found in the tropics, is one of the most prevalent forms of Flavivirus infection in humans. Symptomatically, it is characterized by fever, arthralgia, headache, and rash. Ophthalmic manifestations can involve both the anterior and posterior segment. Panophthalmitis is rare in dengue hemorrhagic fever, and there is no report of culture-positive panophthalmitis in this setting. Here, we report a case of a serology-positive 33-year-old male patient of dengue hemorrhagic fever who developed sudden onset pain, redness, and proptosis in the right eye. The patient subsequently developed panophthalmitis in his right eye, and Bacillus cereus was isolated from eviscerated sample. This case provides unique insights into pathogenesis of panophthalmitis in dengue and highlights the management options.
