Abstract
In clinical settings, the benefit of statin for stroke is debatable as regular statin users may suffer from myalgia, statin-associated myopathy (SAM), and rarely rhabdomyolysis. Studies suggest that patients on statin therapy show lesser vulnerability toward ischemic stroke and post-stroke frailty. Both pre- and post-treatment benefits of statin have been reported as evident by its neuroprotective effects in both cases. As mitochondrial dysfunction following stroke is the fulcrum for neuronal death, we hereby explore the role of statin in alleviating mitochondrial dysfunction by regulating the mitochondrial dynamics. In the present study, we intend to evaluate the role of statin in modulating cardiolipin-mediated mitochondrial functionality and further providing a therapeutic rationale for repurposing statins either as preventive or an adjunctive therapy for stroke.

Abstract
BACKGROUND AND PURPOSE The trochlear nerve has traditionally been difficult to identify on MR imaging. The advent of 7T MR imaging promises to greatly benefit visualization of small structures due to gains in the signal-to-noise ratio allowing improved spatial resolution. We investigated the utility of a clinically feasible ultra-high-resolution 7T MR imaging protocol for identification of the trochlear nerve, as well as assessment of normal trochlear nerve anatomy. MATERIALS AND METHODS Coronal high-resolution 2D T2-weighted TSE images used in a 7T epilepsy protocol of 50 subjects at our institution were reviewed by 2 independent radiologists for visualization of the trochlear nerve at the nerve origin and cisternal, tentorial, and cavernous segments. The frequency of nerve visibility within these segments and their anatomy were documented, and disagreements were resolved by joint review. RESULTS Of the 100 nerves reviewed in 50 subjects, at least 2 segments of the trochlear nerve from the brainstem to the cavernous sinus were identified in 100% of cases. The origins from the brainstem and cisternal segment were visible in 65% and 93% of nerves, respectively. The trochlear nerve was identified at the trochlear groove in 100% of cases and in the posterior wall of the cavernous sinus in 74% of cases. CONCLUSIONS Coronal high-resolution 2D TSE at 7T reliably identified the trochlear nerve throughout its course and is a promising tool for imaging patients with suspected trochlear nerve pathology.

Abstract
Background The development of coronary artery disease (CAD) is strongly influenced by genetic and environmental factors. Monozygotic twins represent a unique population that provides insights into the interaction of genetic, environmental, and social factors and their effects on the development of CAD. Case summary Two 54-year-old identical twins presented to an outside hospital with acute chest pain. Twin B developed chest pain after witnessing Twin A in distress from an acute chest pain episode. Electrocardiogram performed on each of them was diagnostic of ST-elevation myocardial infarction. Upon arrival at the angioplasty centre, Twin A was taken for emergency coronary angiography yet his pain subsided on the way to the catheterization lab hence, Twin B was taken for angiography instead. Twin B angiography demonstrated acute occlusion of the proximal left anterior descending coronary artery and was treated with percutaneous coronary intervention. Twin A coronary angiogram demonstrated 60% ostial first diagonal branch stenosis with a normal distal flow. He was diagnosed with possible coronary vasospasm. Conclusion This is the first report of a simultaneous presentation of monozygotic twins with ST-elevation acute coronary syndrome. While genetic and environmental contributions to the development of CAD have been described, this case highlights the strong social bond that exists between monozygotic twins. Once CAD is diagnosed in one twin, aggressive risk factor modification and screening should be implemented in the other.

Background
Cardiovascular risk scores serve as a useful tool to reinforce the importance of lifestyle modifications and treatment compliance. Yet, there remains a gap between advice by the physician and its implementation by the patient. Digital therapeutics (DTx) as a technology based approach can help bridge this gap. In this context, knowing the quantum of change in disease outcomes and long term cardiovascular risk after DTx implementation can be helpful in persuading the patients for lifestyle interventions.
Purpose
To evaluate the change in cardiovascular risk scores in hypertensive patients after a digital therapeutic intervention.
Method
We conducted a prospective, single arm, 12-week intervention trial at two primary care sites in India. A total of 125 subjects within the age group of 30-65 years with primary hypertension (≥ 140/90 mmHg) were enrolled. They were provided DTx intervention which consisted of modification in diet, physical activities, self-monitoring and health education superimposed on behavior science theories. Atherosclerotic Cardiovascular Disease (ASCVD) risk scores from Pooled Cohort Equation were calculated for all subjects before & after the DTx intervention and the change in score was assessed.
Results
We received the data of 116 patients having a mean age of 47.66 ± 9.47 years and mean BMI of 27.20 ± 4.77 Kg/m². After DTx intervention, the change in mean systolic blood pressure, among other ASCVD equation parameters, was -26.38 mmHg (154.77 vs 128.39 mmHg, P<0.001). The corresponding post-intervention 10-year mean ASCVD risk score for the sample population decreased by 4.74% (11.86% vs 7.12%, P<0.001). The 10-year mean relative risk of ASCVD decreased by 39.95 %. Similarly ASCVD lifetime risk score decreased by 3.04% (49.54% vs 46.50%, P<0.001), amounting to mean relative risk reduction of 6%. Female subjects (n=60) showed higher 10-year mean ASCVD risk reduction of 5.70% (11.70% vs 6.00%, P<0.001), compared to male subjects (n=56) who showed 10-year mean ASCVD risk reduction of 3.76% (12.06% vs 8.30%, P<0.001). This amounted to a relative risk reduction of 48.69% and 30.71% for female & male subjects, respectively. Patients with stage 1 hypertension (n=82) showed a reduction in 10-year mean ASCVD risk of 2.86% (9.90% vs 7.04%, P<0.001). Patients with stage 2 (n=30) & stage 3 hypertension (n=4) achieved higher 10-year mean ASCVD risk reduction of 8.67% (16.07% vs 7.40%, P<0.001) & 13.6% (20.88% vs 7.20%, P=.006).
Conclusion
Digital therapeutics enabled intervention has caused a significant decrease in 10-year & lifetime ASCVD risks which can eventually lead to a decrease in cardiovascular complications, morbidity and mortality. Therefore, such intervention programs should be further explored and studied.

Background
Digital therapeutics (DTx) has emerged as a new approach in recent years making use of connected devices, smartphone software and electronic communication tools to help manage chronic cardiovascular diseases such as hypertension. Considering its nascent stage, many questions still remain with respect to its applicability, effectiveness and limitations.
Purpose
Assess the effectiveness of digital therapeutic intervention in controlling blood pressure in Indian patients with primary hypertension
Methods
We conducted a prospective, 12 week, single arm, interventional study, including 125 subjects at multiple sites in India. Subjects with uncontrolled primary hypertension (≥140 mmHg systolic and/or ≥90 mmHg diastolic) in the age group of 30-65 years who were under routine antihypertensive treatment were enrolled. They were provided supplementary DTx intervention comprising of smartphone application based personalized management of diet, exercise, self monitoring and health education by nutritionists and health coaches. Efficacy endpoints such as blood pressure (BP), body mass index (BMI), lipids, etc. were measured before and after the intervention.
Results
A total of 122 subjects who completed the trial had mean age of 47.44 ± 9.43 years, comprising 58 (48%) male and 64 (52%) female patients and mean BMI of 27.21 ±4.7 kg/m². Post-intervention change in mean systolic BP (SBP) was -25.61 mmHg (95% CI 22.55 - 28.66, 154.98 mmHg vs 129.37 mmHg, P<.001). The post-intervention change in mean diastolic BP (DBP) was -18.62 mmHg (95% CI 16.29 - 20.96, 100.04 mmHg vs 81.42 mmHg, P<.001). Patients with stage 1 hypertension (69.6%) achieved mean systolic reduction of 20.87 ± 13.9 mmHg, (148.54 mmHg vs 127.67 mmHg, P<.001). The patients with stage 2 (27.04%) and stage 3 (3.27%) hypertension achieved a higher mean SBP reduction of 34.67 ± 15.19 mmHg (167.24 mmHg vs 132.58 mmHg, P<.001) and 51.5 ± 40.45 mmHg (190.75 mmHg vs 139.25 mmHg, P=.084), respectively. Male and female patients showed almost similar reduction in systolic BP of 25.47 ± 14.72 and 25.73 ± 19.39 mmHg, respectively. Also, the subjects with other chronic comorbidities (23.9%) achieved a mean systolic BP reduction of 29.51 ± 15.25 mmHg.
A total of 79.51% (n=97) patients achieved the SBP <140 mmHg, while 59.84% (n=73) patients achieved SBP <130 mmHg. Combining both the systolic and diastolic targets together, 65.57% (n=80) patients achieved the target of <140/90 mmHg, while ESC/ESH 2018 recommended BP target of <130/80 mmHg was achieved by 31.15% (n=38) patients.
Conclusion
The implementation of Digital therapeutic application integrated with primary healthcare resulted in significant reduction in blood pressure in participants with uncontrolled hypertension. Greater improvement was observed in participants with higher baseline blood pressure.

Abstract
BACKGROUND Although well known in clinical practice, research in lichen planus pigmentosus and related dermal pigmentary diseases is restricted due to lack of consensus on nomenclature and disease definition. AIMS AND OBJECTIVES Delphi exercise to define and categorise acquired dermal pigmentary diseases. METHODS Core areas were identified including disease definition, etiopathogenesis, risk factors, clinical features, diagnostic methods, treatment modalities and outcome measures. The Delphi exercise was conducted in three rounds. RESULTS Sixteen researchers representing 12 different universities across India and Australia agreed to be part of this Delphi exercise. At the end of three rounds, a consensus of >80% was reached on usage of the umbrella term 'acquired dermal macular hyperpigmentation'. It was agreed that there were minimal differences, if any, among the disorders previously defined as ashy dermatosis, erythema dyschromicum perstans, Riehl's melanosis and pigmented contact dermatitis. It was also agreed that lichen planus pigmentosus, erythema dyschromicum perstans and ashy dermatosis did not differ significantly apart from the sites of involvement, as historically described in the literature. Exposure to hair colours, sunlight and cosmetics was associated with these disorders in a significant proportion of patients. Participants agreed that both histopathology and dermatoscopy could diagnose dermal pigmentation characteristic of acquired dermal macular hyperpigmentation but could not differentiate the individual entities of ashy dermatosis, erythema dyschromicum perstans, Riehl's melanosis, lichen planus pigmentosus and pigmented contact dermatitis. LIMITATIONS A wider consensus involving representatives from East Asian, European and Latin American countries is required. CONCLUSION Acquired dermal macular hyperpigmentation could be an appropriate conglomerate terminology for acquired dermatoses characterised by idiopathic or multifactorial non-inflammatory macular dermal hyperpigmentation.

Abstract
Aim The study investigate the severity of perceived stress and wide domains of psychiatric symptoms reported on initial screening in hospitalized patients of COVID-19 with a second aim to determine the role of sociodemographic factors and coping styles in the hospitalized patients of COVID-19. Method Total 224 patients of COVID-19 infection, hospitalized in various isolation facilities were assessed via web-based self-reported questionnaires on perceived stress scale, brief cope inventory, and DSM-5 crosscutting level-1 questionnaire. Results Majority of the patients reported moderate level of stress followed by mild and severe. Depression and Anxiety symptoms were most common psychopathologies though the patients have reported greater severity in various domains of psychiatric symptoms. Coping styles explains most of variance (64.8%) of the perceived stress. Similarly total PSS scores, coping styles, COVID-19 status and sociodemographic factors contributed significantly to the variance of all psychiatric symptoms. Conclusion Factors like female gender, being married, belonging to nuclear families, service class and urban domicile are the significant factors determining higher risk of stress and developing more psychopathologies. Furthermore, coping styles used by the patients have a greater moderating effect on mental health symptoms and their perceived stress which can be a major area for interventions to reduce the mental health morbidities.

Abstract
Background Cutaneous adnexal tumours (CATs) are one of the commonest clinical presentations in dermatology outpatients. They constitute a subset of skin tumours with a common clinical presentation and variable histological findings. Almost all of them clinically present as a subcutaneous nodule. Depending upon the site and distribution, the clinician can suspect the diagnosis. However, histopathological examination is the gold standard for the definitive diagnosis and proper subtyping of CATs. Aims The present study is conducted to see the overall spectrum, incidence and distribution of CATs in a large cohort at the tertiary care centre with their clinical profile. Methods This was a retrospective study in which all the CATs diagnosed over a period of 5 years (2015 to 2019) in a tertiary care hospital were studied. Clinical data were recorded from the histopathology requisition forms. Results Three hundred and ninety-five cases of CATs were retrieved. Approximately 90% of cases were benign and 10% were malignant. The age of presentation ranged from 8 months to 81 years with male preponderance in all the histological subtypes. The most common site was the head and neck followed by the extremities. Morphologically, the maximum cases showed a differentiation towards sweat glands (44%), followed by sebaceous (29%), follicular (26.5%) and apocrine differentiation (5.3%). Malignant tumours were common in the elderly age group with sebaceous carcinoma being the commonest. Conclusion CATs comprise of a wide spectrum of tumours occurring in all age groups. Malignant CATs are rare and common in older age groups. Histopathological examination is the gold standard in distinguishing between the different subtypes.

Abstract
IMPORTANCE After 10 pack-years of smoking was initially established as a threshold for risk stratification, subsequent clinical trials incorporated it to identify candidates for treatment deintensification. However, several recent studies were unable to validate this threshold externally, and the threshold for smoking exposure remains unclear. OBJECTIVE To estimate the threshold of pack-years of smoking associated with survival and tumor recurrence among patients with head and neck cancer. DESIGN, SETTING, AND PARTICIPANTS This single-institution, cohort study included patients with nonmetastatic head and neck cancer receiving chemoradiation from January 2005 to April 2021. Data were analyzed from January to April 2022. EXPOSURES Heavy vs light smoking using 22 pack-years as a threshold based on maximizing log-rank test statistic. MAIN OUTCOMES AND MEASURES Overall survival (OS), progression-free survival (PFS), locoregional failure (LRF), and distant failure (DF). RESULTS A total of 518 patients (427 male [82.4%]; median [IQR] age, 61 [55-66] years) were included. Median (IQR) follow-up was 44.1 (22.3-72.8) months. A nonlinear Cox regression model using restricted cubic splines showed continuous worsening of OS and PFS outcomes as pack-years of smoking increased. The threshold of pack-years to estimate OS and PFS was 22. Cox multivariable analysis (MVA) showed that more than 22 pack-years was associated with worse OS (adjusted hazard ratio [aHR] 1.57; 95% CI, 1.11-2.22; P = .01) and PFS (aHR, 1.38; 95% CI, 1.00-1.89; P = .048). On Fine-Gray MVA, heavy smokers were associated with DF (aHR, 1.71; 95% CI, 1.02-2.88; P = .04), but not LRF (aHR, 1.07; 95% CI, 0.61-1.87; P = .82). When 10 pack-years of smoking were used as a threshold, there was no association for OS (aHR, 1.23; 95% CI, 0.83-1.81; P = .30), PFS (aHR, 1.11; 95% CI, 0.78-1.57; P = .56), LRF (aHR, 1.19; 95% CI, 0.64-2.21; P = .58), and DF (aHR, 1.45; 95% CI, 0.82-2.56; P = .20). Current smoking was associated with worse OS and PFS only among human papillomavirus (HPV)-positive tumors (OS: aHR, 2.81; 95% CI, 1.26-6.29; P = .01; PFS: aHR, 2.51; 95% CI, 1.22-5.14; P = .01). CONCLUSIONS AND RELEVANCE In this cohort study of patients treated with definitive chemoradiation, 22 pack-years of smoking was associated with survival and distant metastasis outcomes. Current smoking status was associated with adverse outcomes only among patients with HPV-associated head and neck cancer.

Abstract
Abdominal hydatid cyst disease mostly involves the liver. Involvement of the pancreas as an isolated primary organ is rare accounting for < 2% of all systemic echinococcosis cases. It mostly involves the head of the pancreas. Symptoms depend on the location, size, and associated complications; therefore, it can have varied presentations including acute pancreatitis. On imaging, it can mimic other common pancreatic cystic lesions like pseudocyst or cystic neoplasm. Accurate preoperative diagnosis is usually difficult and requires a very high index of suspicion even in endemic areas. Herein, a case of primary isolated hydatid cyst of the pancreas that was initially diagnosed and managed as acute pancreatic pseudocyst is reported.

Abstract
Numerous human pathogens, especially Gram-negative bacteria, are able to enter the viable-but-non-culturable (VBNC) state when they are exposed to environmental stressors and pose the risk of being resuscitated and causing infection after the removal of the trigger. Widely used food preservatives like weak organic acids are potential VBNC inducers in food processing and packaging facilities but have only been reported for food-borne pathogens. In the present study, it is demonstrated for the first time that one such agent, formic acid (FA), can induce a VBNC state at food processing, storage, and distribution temperatures (4, 25, and 37°C) with a varied time of treatment (days 4-10) in pathogenic Gram-negative bacteria Acinetobacter baumannii and Klebsiella pneumoniae. The use of hospital-associated pathogens is critical based on the earlier reports that demonstrated the presence of these bacteria in hospital kitchens and commonly consumed foods. VBNC induction was validated by multiple parameters, e.g., non-culturability, metabolic activity as energy production, respiratory markers, and membrane integrity. Furthermore, it was demonstrated that the removal of FA was able to resuscitate VBNC with an increased expression of multiple virulence and Antimicrobial Resistance (AMR) genes in both pathogens. Since food additives/preservatives are significantly used in most food manufacturing facilities supplying to hospitals, contamination of these packaged foods with pathogenic bacteria and the consequence of exposure to food additives emerge as pertinent issues for infection control, and control of antimicrobial resistance in the hospital setting.

Abstract
OBJECTIVES We sought to define the optimal threshold for anemia in North American head and neck cancer patients and evaluate its role as a prognostic biomarker. MATERIALS AND METHODS A single-institution database was queried for patients with head and neck cancer who underwent chemoradiation from January 2005 to April 2021. An optimal threshold of hemoglobin (Hgb) level was defined based on maximum log-rank test statistic. Cox multivariable analysis (MVA), Kaplan-Meier, and propensity score matching were performed to evaluate treatment outcomes. RESULTS A total of 496 patients were identified. Threshold for Hgb was determined to be 11.4 for both overall survival (OS) and progression-free survival (PFS). Low Hgb was associated with worse OS (adjusted hazards ratio [aHR] 2.41, 95 % confidence interval [CI] 1.53-3.80, p < 0.001) and PFS (aHR 2.01, 95 % CI 1.30-3.11, p = 0.002). Similar findings were observed among 39 matched pairs for OS (5-year OS 22.3 % vs 49.0 %; HR 2.22, 95 % CI 1.23-4.03, p = 0.008) and PFS (5-year PFS 24.3 % vs 39.1 %; HR 1.78, 95 % CI 1.02-3.12, p = 0.04). Among those with HPV-negative tumors, low Hgb was associated with worse OS (aHR 13.90, 95 % CI 4.66-41.44, p < 0.001) and PFS (aHR 5.24, 95 % CI 2.09-13.18, p < 0.001). However, among those with HPV-positive tumors, low Hgb was not associated with both OS (aHR 1.75, 95 % CI 0.60-5.09, p = 0.31) and PFS (aHR 1.13, 95 % CI 0.41-3.14, p = 0.82). CONCLUSION AND RELEVANCE Low Hgb below 11.4 was an independent adverse prognostic factor for worse survival. It was also prognostic among patients with HPV-negative tumors, but not for HPV-positive tumors.
