Biosynthesis of benzyl cinnamate utilizing an successful immobilized lipase entrapped in nano-molecular parrot cages.
In multivariable logistic regression model, only AL ≥ 30 mm was associated with clinically significant IOL decentration (OR=1.65, P=0.002). AL ≥ 30mm (OR=2.09, P=0.001) was independent risk factors for clinically significant IOL tilt after adjusting for confounders. AL ≥ 30.3 mm could effectively predict IOL decentration ≥ 0.6mm (area under the curve = 0.802).

Participants with AL longer than 30mm have higher risk of clinically significant IOL decentration and tilt, thus cautious should be taken to implant multifocal or toric IOL for these patients.

To evaluate current practices of tracheostomy in children regarding the ideal timing of tracheostomy placement, complications, indications, mortality, and success in decannulation.

The authors searched PubMed, Embase, Cochrane Library, Google Scholar, and complemented by manual search. The guidelines of PRISMA and MOOSE were applied. The quality of the included studies was evaluated with the Newcastle-Ottawa Scale. Information extracted included patients' characteristics, outcomes, time to tracheostomy, and associated complications. Odds ratios (ORs) with 95% CIs were computed using the Mantel-Haenszel method.

Sixty-six articles were included in the qualitative analysis, and 8 were included in the meta-analysis about timing for tracheostomy placement. The risk ratio for "death in hospital outcome" did not show any benefit from performing a tracheostomy before or after 14 days of mechanical ventilation (p=0.49). The early tracheostomy before 14 days had a great impact on the days of mechanical ventilation (-26 days in mean difference, p<0.00001). The authors also found a great reduction in hospital length of stay (-31.4 days, p<0.008). For the days in PICU, the mean reduction was of 14.7 days (p<0.007).

The meta-analysis suggests that tracheostomy performed in the first 14 days of ventilation can reduce the time spent on the ventilator, and the length of stay in the hospital, with no effect on mortality. The decision to perform a tracheostomy early or late may be more dependent on the baseline disease than on the time spent on ventilation .

Serum lab data revealed lymphopenia and computed tomography imaging of the chest exhibited multiple ground-glass patches in bilateral lung fields. COVID-19 was suspected and further examination was done. But patient's dyspnea progressed while waiting for the result of COVID-19 examination and respiratory failure with cardiac arrest occurred eventually, acute myocardial infarction was diagnosed then. This article is aimed to discuss the dilemmas in managing acute myocardial infarction during COVID-19 pandemic.
Geographic atrophy is a major vision-threatening manifestation of age-related macular degeneration, one of the leading causes of blindness globally. Geographic atrophy has no proven treatment or method for easy detection. Rapid, reliable, and objective detection and quantification of geographic atrophy from optical coherence tomography (OCT) retinal scans is necessary for disease monitoring, prognostic research, and to serve as clinical endpoints for therapy development. To this end, we aimed to develop and validate a fully automated method to detect and quantify geographic atrophy from OCT.

We did a deep-learning model development and external validation study on OCT retinal scans at Moorfields Eye Hospital Reading Centre and Clinical AI Hub (London, UK). A modified U-Net architecture was used to develop four distinct deep-learning models for segmentation of geographic atrophy and its constituent retinal features from OCT scans acquired with Heidelberg Spectralis. A manually segmented clinical dataset fodation FUNDING Apellis Pharmaceuticals.
We present a fully developed and validated deep-learning composite model for segmentation of geographic atrophy and its subtypes that achieves performance at a similar level to manual specialist assessment. Fully automated analysis of retinal OCT from routine clinical practice could provide a promising horizon for diagnosis and prognosis in both research and real-life patient care, following further clinical validation FUNDING Apellis Pharmaceuticals.
Cancer-associated thrombosis is a leading cause of morbidity and mortality in malignancy patients. Prophylactic anticoagulation is under-utilized and the cost of low-molecular-weight heparin (LMWH) and direct oral anticoagulants is a major barrier in developing countries.

A retrospective analysis was performed of all cancer-associated thrombosis patients attending the thrombosis clinic at a tertiary-level referral hospital based in North India between 2011 and 2015. Patient demographics and disease-related parameters were collected and analyzed.

A total of 771 patients attended the thrombosis clinic during study period, of which 64 cases were malignancy-associated. Of these, 56% of the patients were female and 20% were bedridden. The median age was 48.5 years, adenocarcinoma (48%) being the most common histological subtype. Gynecological malignancies (30%) were the most common malignancies, followed by genitourinary (11%) malignancies. Most of the cases occurred during first year of diagnosis (51%), and only 14% occurred after 3 years. Most of the patients were on combined treatment. Almost 40% of the patients developed thrombosis within 30 days of surgical treatment. Lower limb thrombosis was the most commonly seen type (56%), while abdominal and pulmonary thrombosis were both seen in 5%. Patients were managed with LMWH and vitamin K antagonists (84.3%) and only 6.25% with LMWH alone. Direct oral anticoagulants were not commonly used during the study period.

At the hospital studied, most of the cases occurred early in the disease course. Postoperative prophylaxis could have contributed towards reducing thrombosis in the peri-operative period. Early suspicion and prompt treatment can improve quality of life in such patients.

Hypothyroidism is one of the leading conditions in endocrinology. Despite that fact, clinical indications for treatment still vary among Spanish specialists.

To identify attitudes of Spanish specialists relating to the use of levothyroxine (LT4) and the management of hypothyroidism.

The members of the Sociedad Española de Endocrinología y Nutrición (Spanish Society of Endocrinology and Nutrition) were invited to participate in a web-based survey. The survey, initially in English, was modified to reflect in accordance with the availability of thyroid hormone formulations in Spain.

A total of 505 of 1956 (25.8%) members (66% female) completed the survey; 97.4% declared that LT4 is the first-line therapy for hypothyroidism. The indications for LT4 therapy in euthyroidism were infertility in thyroid antibody-positive women (48.5%) and simple goitre (21.2%). However, 44.2% of specialists reported that there was no indication for LT4 therapy in such patients. Only a minority of respondents (2.6%) considered combining LT4 with liothyronine as the treatment of choice from inception, whereas 49% stated that it should never be used.

The standard of treatment of hypothyroidism in Spain is almost exclusively with LT4 tablets. Availability of other formulations of LT4 or combination therapy for hypothyroidism management remains to be explored, especially in patients with persistent symptoms. Notably, non-evidence-based use of LT4 is widely practiced in Spain for euthyroid women with autoimmune thyroiditis and fertility issues.

Veliparib From a pathophysiological point of view, it is classified into two types polyuria due to a greater excretion of solutes (urine osmolality >300 mOsm/L) or due to an inability to increase solute concentration (urine osmolality less then 150 mOsm/L). Sometimes both mechanisms can coexist (urine osmolality 150-300 mOsm/L). Polyuria is a diagnostic challenge and its proper treatment requires an evaluation of the medical record, determination of urine osmolality, estimation of free water clearance, use of water deprivation tests in aqueous polyuria, and measurement of electrolytes in blood and urine in the case of osmotic polyuria.Hypertension (HT) is one of the main risk factors for cardiovascular disease (CVD). Although it is a global problem, independently of economic situation, region, race or culture, the data available on Latin America are limited. Clinical guidelines emphasise the importance of obtaining reliable blood pressure readings. For this reason, the use of ambulatory blood pressure monitoring (ABPM) is recommended. This improves precision and reproducibility, resulting in better diagnosing and therapeutic decision-making, and constitutes a better estimation of prognosis than office measurements. Unfortunately, there is no global prospective ABPM registry for all of Latin America that analyses HT prevalence, the level of knowledge about it, treatment percentage and the degree of control. Consequently, the authors of this article consider its implementation a priority.
The present report updates the main characteristics and outcomes of heart transplants in Spain to 2020.

We describe the main features of recipients, donors, surgical procedure, and immunosuppression in 2020. We also analyze the temporal trends of these characteristics and outcomes (survival) for the period 2011 to 2019.

In 2020, 278 heart transplants were performed (7.3% decrease vs 2019). The findings in 2020 confirmed previous observations of an increase in pretransplant sternotomy, a slight decrease in urgent transplants carried out with ventricular assist devices, a slight decrease in donor age, an increase in the use of allografts with previous arrest, and a decrease in ischemia time. Survival continued to improve in recent triennia, reaching 82.0% at 1 year in the period 2017 to 2019.

The slight decrease in the number of heart transplants performed in 2020 in Spain, most likely due to the SARS-CoV-2 pandemic, did not change the main characteristics of the procedure. No change was observed in the tendency to improved survival.
