The update on immunotherapy along with PD-1 and PD-L1 restriction.
Further research is urgently needed.
The objective was to investigate the delay between the onset of DVT symptoms and start of anticoagulation in common practice, assess whether this has any impact on the recanalization of venous thrombosis over one year follow up.

A prospective observational study on 76 consecutive patients (39 men, 51.3%) with DVT diagnosed using compression ultrasound (CUS). Timing was classified as very early treatment ≤72 hours, early treatment ˂7 days and late treatment ≥7 days from onset of symptoms. Further development of the disease was monitored by CUS in scheduled visits 1, 3, 6 and 12 months after the start of treatment.

Mean delay from symptom onset to the start of anticoagulation was 11.1 days (median 7 days, range 1-42 days) with significant difference (p˂0.05) between proximal (12.9 days, median 30 days) and distal DVT (6.5 days, median 2 days). In less than 25% of all patients, with both proximal and distal DVT, treatment was started very early (≤72 hours), 40 patients (52.6%) received late treatment ≥7 dapatients with distal DVT compared to patients with proximal DVT. A very significant positive correlation between delay in treatment and rate of incomplete recanalization of proximal and distal thrombosis indicates that delayed anticoagulation could be a signal risk factor for the incomplete recanalization and development of PTS.
Computable phenotypes allow identification of well-defined patient cohorts from electronic health record data. Little is known about the accuracy of diagnostic codes for important clinical concepts in pediatric epilepsy, such as (1) risk factors like neonatal hypoxic-ischemic encephalopathy; (2) clinical concepts like treatment resistance; (3) and syndromes like juvenile myoclonic epilepsy. We developed and evaluated the performance of computable phenotypes for these examples using electronic health record data at one center.

We identified gold standard cohorts for neonatal hypoxic-ischemic encephalopathy, pediatric treatment-resistant epilepsy, and juvenile myoclonic epilepsy via existing registries and review of clinical notes. From the electronic health record, we extracted diagnostic and procedure codes for all children with a diagnosis of epilepsy and seizures. We used these codes to develop computable phenotypes and evaluated by sensitivity, positive predictive value, and the F-measure.

For neonate heterogeneity of success using administrative data to identify cohorts important for pediatric epilepsy research.
The variable accuracy of our computable phenotypes (hypoxic-ischemic encephalopathy high, treatment resistance medium, and juvenile myoclonic epilepsy low) demonstrates the heterogeneity of success using administrative data to identify cohorts important for pediatric epilepsy research.
Coronavirus disease 2019 (COVID-19) pandemic is a worldwide public health crisis. During huge surge in COVID-19 cases, most of the patient arrived at Rajiv Gandhi Government General Hospital, Chennai were severe due to late presentation and also available evidence demonstrating that the delay in treatment is directly associated with increased mortality or poor patient outcome. As an innovative concept of Zero Delay COVID-19 Ward were set up to provide the required critical care for all severe COVID-19 cases. The experience of setting up of such Zero Delay COVID-19 Ward and profile of admitted COVID-19 patients were described in this paper.

A total of 4515 laboratory-confirmed COVID-19 patients admitted at Zero Delay COVID-19 Ward was analyzed retrospectively from 7th July to 31st December 2020.

At the time of admission the frequency of dyspnea were 85.6% among them 99.1% recovered from dyspnea after the oxygen therapy and other management at Zero Delay COVID-19 Ward. Of the 4515 COVID-19 individuals, about 1829 (40.5%) had comorbidity, 227 (5%) had died. Multivariable logistic regression analysis, COVID-19 death was more likely to be associated with comorbidity (OR 18.687; 95% CI 11.229-31.1) than other variables.

Comorbidity is an independent high risk factor for mortality of COVID-19 patients. From our observation, it is strongly recommended that effective zero delay covid-19 ward model will help for the prevention of mortality in current/expected waves of COVID-19.

Lifelong follow-up after endovascular abdominal aortic aneurysm repair (EVAR) is recommended due to a continued risk of complications, especially if the first postoperative imaging shows abnormal findings. We studied the long-term outcomes in patients with abnormalities on the first postoperative computed tomography angiography (CTA) following EVAR.

This is a retrospective study of all consecutive patients who underwent elective EVAR for nonruptured abdominal aortic aneurysm (AAA) between January 2007 and January 2012 in 16 Dutch hospitals with follow-up until December 2018. Patients were included if the first postoperative CTA showed one of the following abnormal findings endoleak type I-IV, endograft kinking, infection, or limb occlusion. AAA diameter, complications, and secondary interventions during follow-up were registered. Primary endpoint was overall survival, and other endpoints were secondary interventions and intervention-free survival. Kaplan-Meier analyses were used to estimate overall and inrs was 82.9%, 61.3%, and 45.6%, respectively.

Patients with abnormalities on the first postoperative CTA after elective EVAR for infrarenal AAA cannot be discharged from regular imaging follow-up due to a high risk of secondary interventions. Patients who had a secondary intervention had similar overall survival as those without secondary interventions.

We conducted an audit examining the true fasting times of mothers undergoing an elective caesarean section and the incidence of urinary ketones before and after introducing a preop carbohydrate drink (Nutricia preOp 400ml) to be administered to all patients at 6am on the day of surgery. We audited 50 patients prior to introducing the preop carbohydrate drink and 54 patients after the introduction of a carbohydrate drink. We found the mean fasting time from last caloric intake was reduced from 13h 35min to 5h 5min after the introduction of a preoperative carbohydrate drink. We found that the incidence of urinary ketones was 40.4% prior to the introduction of a preoperative carbohydrate drink and 38.3% after the introduction of a preop drink (p = 1). If fasting times were limited to under 4h, the incidence of urinary ketones is 10%. Our audit demonstrates that reducing preoperative fasting times is possible and preventing metabolic derangements may be possible, requiring an approach targeted at keeping fasting times to a minimum.We report a case series of children with childhood apraxia of speech, by describing behavioral and white matter microstructural changes following 2 different treatment approaches.Five children with childhood apraxia of speech were assigned to a motor speech treatment (PROMPT) and 5 to a language, nonspeech oral motor treatment. Speech assessment and brain MRI were performed pre- and post-treatment. The ventral (tongue/larynx) and dorsal (lips) corticobulbar tracts were reconstructed in each subject. Mean fractional anisotropy and mean diffusivity were extracted. The hand corticospinal tract was assessed as a control pathway. In both groups speech improvements paralleled changes in the left ventral corticobulbar tract fractional anisotropy. The PROMPT treated group also showed fractional anisotropy increase and mean diffusivity decrease in the left dorsal corticobulbar tract. No changes were detected in the hand tract. Our results may provide preliminary support to the possible neurobiologic effect of a multimodal speech motor treatment in childhood apraxia of speech.Introduction Children with systemic lupus erythematosus have a more challenging and difficult course as compared to their adult counterparts. Today, the aim of therapy for any child with lupus is to keep the child in a state of sustained remission with minimal or no use of steroids. This laudable goal is often difficult to achieve for the child with lupus. Eeyarestatin 1 mw In addition to the use of disease modifying agents, sometimes in combination, Rituximab (RTX) is also used as an off-label indication to manage such patients.Objectives To study the use, efficacy and safety of RTX in a cohort of patients with pediatric lupus followed at a single tertiary level center in Northern India.Methods This paper is a retrospective review looking at the use of RTX in children with systemic lupus at a tertiary level pediatric rheumatology center in North India over a period of seventeen years. This paper describes the indications, use, efficacy and safety of RTX in childhood systemic lupus erythematosus.Results RTX was used in 17 of 225 pediatric lupus patients (7.5%), with the most common indication being resistant renal disease (53%). Significant improvement was seen in all domains studied The mean SLEDAI was 16.25 prior to RTX and reduced to 1.43 six months after the RTX (p value 0.001), steroid use dropped from 100% pre- RTX to 33% at 2 years, there was a sustained reduction in proteinuria in the patients with nephritis from a mean urine spot protein creatinine ratio of 3.1 pre RTX to 0.4 at one year post RTX (p= .006). Finally, 82% of the children had no flare during the follow up (median 24 months). No patient had any adverse event.Conclusions This study confirms that RTX is very effective in childhood lupus and can be safely used even in a country with a very high burden of infectious diseases. This data adds to the scarce literature in this area from the developing world.Anaerobic digestion (AD) for biogas production is affected by many factors that includes organic loading rate (OLR). This OLR appears to be closely linked to various other factors and understanding these linkages would therefore allow the sole use of OLR for process performance monitoring, control, as well as reactor design. This review's objective is to collate the various AD factor specific studies, then relate these factors' role in OLR fluctuations. By further analyzing the influence of OLR on the AD performance, it would then be possible, once all the other factors have been determined and fixed, to manage an AD plant by monitoring and controlling OLR only. Decisions on reactor design, process kinetics, biogas yield and process stability can then be made much more quickly and with minimal troubleshooting steps.
