The aim of this systematic review and meta-analysis was to summarize and compare the available evidence on the level of vitamin D and antioxidant trace elements between the keratoconus (KC) patients and healthy controls. Seven case–control studies with 830 subjects were found eligible with a systematic search using PubMed, SCOPUS, Web of Science, and EMBASE till November 21, 2021. Data were synthesized with a DerSimonian and Laird random-effects method of meta-analysis. The mean serum vitamin D level was significantly lower in the patients with KC [standardized mean difference (SMD): −0.71; P < 0.001] as compared with the control group. The mean serum vitamin D level decreased more in the progressive patients (SMD: −0.80; P = 0.016) than in the stable patients (SMD: −0.66; P < 0.001) when compared with the control group. The mean serum zinc level was found significantly lower in the patients with KC compared with the control group (SMD: −1.98; P = 0.005). Pooled analysis based on the two studies showed significantly lower mean selenium levels in the KC patients (SMD: −0.34; P = 0.003). Regular evaluation of serum vitamin D, zinc, and selenium levels among the patients with KC at disease onset and future follow-ups could be promising in predicting the progressive disease and disease severity.

We describe a case of ALK1 negative (-) pulmonary anaplastic large-cell lymphoma (pALCL) in an adult female with an unfavorable outcome following combination chemotherapy and present a systematic review of 39 such sporadic cases reported over the past 28 years (1990-2018). pALCL occurred in 26 males and 13 females (median age, 43 years [5-81]) and 13/39 (33.33%) were ≤18 years. The lesions were endobronchial in 21 (53.85%) and parenchymal in 18 (46.15%) cases. Twenty-six cases were ALK1-; 13 were ALK1+ (positive); and 27/34 cases had a T cell phenotype (where tested). ALK- cases were characterized by higher age (P = 0.012) at presentation, more B symptoms (P = 0.002), and more parenchymal than endobronchial lesions (P = 0.039). The median survival (N = 29/39) was 60 months; pediatric group had a better survival than adult/elderly group (log-rank, P = 0.026). pALCL is rare and may have a distinct biological behavior.

Aim: Present systematic review and meta-analysis examined the burden of psychological reactions predominantly anxiety, depression, stress, and insomnia during the novel COVID-19 pandemic phase among the frontline healthcare, nonfrontline healthcare, and general population. Material and Methods: PubMed, EMBASE, and SCOPUS were searched for studies between January 1, 2020, and May 25, 2020. Brief protocol of the systematic review was registered with the PROSPERO database, (CRD42020186229). Any study that reported the burden of at least one of psychological reactions including anxiety or depression or stress or insomnia was eligible. Heterogeneity was assessed using I2 statistic and results were synthesized using random-effect meta-analysis. Results: Out of 49 eligible studies, 41 databases from 37 studies reported anxiety, 39 databases (35 studies) reported depression, 20 studies reported stress and 12 databases from 11 studies reported insomnia. The overall prevalence for anxiety, depression, stress, and insomnia was 26.3%, 25.9%, 26.2%, and 31.3%, respectively. Prevalence of anxiety, depression, stress, and insomnia were found highest among the frontline healthcare as compared to general healthcare workers and the general population. Conclusion: Anxiety, depression, stress, and insomnia were more prevalent among frontline health-care workers compared to general. Such increased prevalence is prompting toward the global mental health emergency. Therefore, a call of urgent attention and pan-region effective mental-health intervention are required to mitigate these psychological reactions. [ABSTRACT FROM AUTHOR]

Context: While analyzing locoregional recurrences (LRRs), it is necessary to consider distant metastasis as a competing event. Because, later one is more fatal than LRR. It may change ongoing treatment of breast cancer and may alter the chance of LRR. Although some earlier studies assessed the effect of neoadjuvant chemotherapy (NACT) on LRR, they did not use competing risk regression model for it. Aims: To identify the risk factors and predict LRR using competing risk hazard model and to compare them with those using conventional hazard model. Settings and Design: This was a retrospective study from a tertiary care cancer hospital in India. Subjects and Methods: Data of 2114 breast cancer patients undergoing surgery were used from patient's record files (1993–2014). Statistical Analysis: Fine and Gray competing risk regression was used to model time from surgery to LRR, considering distant metastasis and death as the competing events. Further, cause-specific Cox regression was used to model time from surgery to LRR without considering competing risk. Results: Greater than ten positive nodes (hazard ratio [HR] [95% confidence interval (CI)]: 2.19 [1.18–4.03]), skin involvement (HR [95% CI]: 2.75 [1.50–5.05]), NACT (HR [95% CI]: 1.90 [1.06–3.40]), invasive tumor in inner quadrant (HR [95% CI]: 1.78 [0.98–3.24]), and postoperative radiotherapy (HR [95% CI]: 0.52 [0.29–0.94]) were found to be significantly associated with LRR. However, conventional survival analysis ignoring competing risk overestimated cumulative incidence function and underestimated survival. Competing risk regression provided relatively more precise CI. Conclusions: Competing risks, if any, need to be incorporated in the survival analysis. NACT was found to be associated with higher risk for LRR, which may be because of administering it mainly to patients with bad prognosis.

Background: Population aging is inevitable. Old age is marked with health problems because of aging process, long-term chronic illnesses, also associated with social and mental problems. Objectives: To determine the pattern of physical morbidities in geriatric population and to study the utilization of health services among them. Methods: A cross-sectional study was undertaken from April to September 2017, among 270 consenting elderly people, residing in urban slums under field practice area of a medical college, using a structured interview schedule. Results: Among the 270 elderly, 36.30% were males, 80% belonged to nuclear families. A total of 262 reported of some morbidity, 61.85% had hypertension, 45.19% had diabetes, 37.78% had acid peptic disease, and 51.08% reported to have 1--3 morbidities. Majority (41.85%) of them had visited a physician on an average of 4--6 times in the preceding year. A total of 84.81% went to the urban health center, whereas 24.81% to a government hospital for treatment. Reasons cited for preference of health facility were "free consultation" and "nearby location" (85.19%). A total of 90.74% received allopathic medicines. Conclusion: Prevalence of morbidity was found to be high, which can be attributed to their compromised living conditions. Health-seeking behavior was found to be good. [ABSTRACT FROM AUTHOR]
