Leucodystrophies are a group of white matter diseases caused by an abnormality in the formation or
maintenance of one or more components of the myelin sheath. The devastating course of the disease
coupled with the lack of any defi nitive treatment render them potentially fatal and incurable. Van der
Knaap Syndrome, also known as megaloencephalic leucoencephalopathy with subcortical cyst, is a
relatively new and rare entity. Although reported sporadically from Europe, Asia and the Agarwal
community in India, there is practically no case report from the eastern part of India. We present a
case of van der Knaap syndrome in an adult female with some atypical features.

Soil test crop response (STCR) correlation studies were carried out in Vindhyan alluvial plain during 2001 to 2004taking IR-36 as test crop to quantify rice production in the context of the variability of soil properties and use of balanced fertilizers based on targeted yield concept. The soils were developed on gently sloping alluvial plain with different physiographic settings and notable variation in drainage condition. Soil properties show moderate variation in texture (loamy to clay), organic carbon content (4.4 to 9.8 g/kg), cation exchange capacity (10.2 to 22.4 cmol (p+)/kg) and pH (5.3 to 6.4). Soil fertility status for N is low to medium (224 to 348 kg/ha), P is medium to high (87 to 320 kg/ha) and K ranges from medium to high (158 to 678 kg/ha).Database regarding nutrient requirement in kg/t of grain produce (NR), the percent contribution from the soil available nutrients [CS (%)] and the percent contribution from the applied fertilizer nutrients [CF (%)] were computed for calibrating and formulating fertilizer recommendations. Validity of the yield target for 7 and 8 t/ha was tested in farmers' fields and yields targets varied at less than 10%. The percent achievement of targets aimed at different level was more than 90%, indicating soil test based fertilizer recommendation approach was economically viable within the agro-ecological zone with relatively uniform cropping practices and socio-economic conditions.

Journal of Gastric Cancer 2020;20(3):313-327
Purpose:
Nodal downstaging after preoperative therapy for gastric cancer has been shown to impart excellent prognosis, but this has not been validated in a national cohort. The role of neoadjuvant chemoradiation (NACR) in nodal downstaging remains unclear when compared with that of neoadjuvant chemotherapy alone (NAC). Furthermore, it is unknown whether the prognostic implications of nodal downstaging differ by preoperative regimen.
Materials and Methods:
Using the National Cancer Database, overall survival (OS) duration was compared among natural N0 (cN0/ypN0), downstaged N0 (cN+/ypN0), and nodepositive (ypN+) gastric cancer patients treated with NACR or NAC. Factors associated with nodal downstaging were examined in a propensity score-matched cohort of cN+ patients, matched 1:1 by receipt of NACR or NAC.
Results:
Of 7,426 patients (natural N0 [n=1,858, 25.4%], downstaged N0 [n=1,813, 24.4%], node-positive [n=3,755, 50.4%]), 58.2% received NACR, and 41.9% received NAC. The median OS durations of downstaged N0 (5.1 years) and natural N0 (5.6 years) patients were similar to one another and longer than that of node-positive patients (2.1 years) (P<0.001). In the matched cohort of cN+ patients, more recent diagnosis (2010–2015 vs. 2004–2009) (odds ratio [OR], 2.57; P<0.001) and NACR (OR, 2.02; P<0.001) were independently associated with nodal downstaging. The 5-year OS rate of downstaged N0 patients was significantly lower after NACR (46.4%) than after NAC (57.7%) (P=0.003).
Conclusions
Downstaged N0 patients have the same prognosis as natural N0 patients.Nodal downstaging occurred more frequently after NACR; however, the survival benefit of nodal downstaging after NACR may be less than that when such is achieved by NAC.

Background:
A daily habit of yogic practice or walking, along with an oral hypoglycemic agent (OHA) could be beneficial for better control of type 2 diabetes mellitus (T2DM). We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to find out the efficiency of yoga or walking on glycemic control in T2DM.
Methodology:
The present systematic review and meta-analysis were completed according to the PRISMA guidelines. The risk of bias in included studies was evaluated, by using the revised Cochrane risk-of-bias tool for randomized trials. Meta-analysis was implemented using RevMan software. Forest plots were used to illustrate the study findings and meta-analysis results.
Results:
Sixteen studies were included in this systematic review, where 1820 participants were allocated to one of the following interventions: yoga, walking, and without any regular exercise (control group). Participants were between 17–75 years of age. Compared to the control group, the yoga group had a significant reduction in fasting blood glucose (FBG) by 31.98 mg/dL (95% CI,–47.93 to –16.03), postprandial blood glucose (PPBG) by 25.59 mg/dL (95% CI, –44.00 to –7.18], glycosylated hemoglobin (HbAlc) by 0.73% (95% CI, –1.24 to -0.22), fasting insulin by 7.19 μIU/mL (95% CI, –12.10 to –2.28), and homeostatic model assessment for insulin resistance (HOMA-IR) by 3.87 (95% CI, –8.40 to -0.66). Compared to the control group, the walking group had a significant reduction in FBG by 12.37 mg/dL (95% CI, –20.06 to –4.68) and HbA1c by 0.35% (95% CI, –0.70 to –0.01). Compared to the walking group, the yoga group had a significant reduction in FBG by 12.07 mg/dL (95% CI, –24.34 to – 0.20), HbA1c by 0.20% (95% CI, –0.37 to –0.04), fasting insulin by 10.06 μIU/mL (95% CI, –23.84 to 3.71) and HOMA-IR by 5.97 (95% CI, –16.92 to 4.99).
Conclusions
Yoga or walking with OHA has positive effects on glycemic control. For the management of T2DM, yoga has relatively more significant effects on glycemic control than walking.

Background:
and Purpose Cerebral venous thrombosis (CVT) is associated with a high degree of morbidity and mortality. Our objective is to elucidate characteristics, treatments, and outcomes of patients with cancer and CVT (CA-CVT).
Methods:
The 2016–2019 National Inpatient Sample (NIS) database was queried for patients with a primary diagnosis of CVT. Patients with a currently active diagnosis of malignancy (CA-CVT) were then identified. Demographics and comorbidities were compared between CA-CVT and CVT patients. Subgroup analyses explored patients with hematopoietic cancer and non-hematopoietic cancers. Stroke severity and treatment were explored. Inpatient outcomes studied were discharge disposition, length of stay, and mortality.
Results:
Between 2016 and 2019, 6,140 patients had a primary diagnosis code of CVT, and 370 (6.0%) patients had a coexisting malignancy. The most common malignancy was hematopoietic (n=195, 52.7%), followed by central nervous system (n=40, 10.8%), respiratory (n=40, 10.8%), and breast (n=40, 10.8%). These patients tended to be older than non-CA-CVT and were more likely to have coexisting comorbidities. CA-CVT patients had higher severity scores on the International Study of Cerebral Vein and Dural Sinus Thrombosis Risk Score (ISCVT-RS) and increased complications. In a propensity-score matched cohort, there were no differences in inpatient outcomes.
Conclusion
Malignancy occurs in 6% of patients presenting with CVT and should be considered a potential comorbidity in instances where clear causes of hypercoagulabilty have not been identified. Malignancy was linked to higher mortality rates. Nonetheless, after adjusting for the severity of CVT, the outcomes for inpatients with cancer-associated CVT were comparable to those without cancer, indicating that the increased mortality associated with malignancy is probably due to more severe CVT conditions.

Journal of Stroke 2023;25(2):223-232
Background:
and Purpose Intracranial arterial stenosis (ICAS)-related stroke occurs due to three primary mechanisms with distinct infarct patterns: (1) borderzone infarcts (BZI) due to impaired distal perfusion, (2) territorial infarcts due to distal plaque/thrombus embolization, and (3) plaque progression occluding perforators. The objective of the systematic review is to determine whether BZI secondary to ICAS is associated with a higher risk of recurrent stroke or neurological deterioration.
Methods:
As part of this registered systematic review (CRD42021265230), a comprehensive search was performed to identify relevant papers and conference abstracts (with ≥20 patients) reporting initial infarct patterns and recurrence rates in patients with symptomatic ICAS. Subgroup analyses were performed for studies including any BZI versus isolated BZI and those excluding posterior circulation stroke. The study outcome included neurological deterioration or recurrent stroke during follow-up. For all outcome events, corresponding risk ratios (RRs) and 95% confidence intervals (95% CI) were calculated.
Results:
A literature search yielded 4,478 records with 32 selected during the title/abstract triage for full text; 11 met inclusion criteria and 8 studies were included in the analysis (n=1,219 patients; 341 with BZI). The meta-analysis demonstrated that the RR of outcome in the BZI group compared to the no BZI group was 2.10 (95% CI 1.52–2.90). Limiting the analysis to studies including any BZI, the RR was 2.10 (95% CI 1.38–3.18). For isolated BZI, RR was 2.59 (95% CI 1.24–5.41). RR was 2.96 (95% CI 1.71–5.12) for studies only including anterior circulation stroke patients.
Conclusion
This systematic review and meta-analysis suggests that the presence of BZI secondary to ICAS may be an imaging biomarker that predicts neurological deterioration and/or stroke recurrence.

Introduction: Worldwide fractures among individuals are a major public health problem. As a result, fracture are
the most common cause of severe enduring pain and physical disability, and they affect innumerable globally. It
has been studied that nutrients that contain high protein helps in the fracture healing process. Eels contains many
nutrients, such as phosphate, calcium, protein, collagen and amino acids that can help bone growth. The aim of this
study was to examine the effect of eel flour (Monopterus albus) at multilevel dose content to accelerate the healing
process of fracture in male Rattus novergicus Wistar Albino rat. Methods: This study design include experimental
study with post-test only on controls group. The wok was conducted from May-June 2019 in the Laboratory of Anatomy of Stikes Piala Sakti Pariaman. The sampling was purposive sampling technique with a sample size of 24 rats.
Results: The results of the ANOVA test have proved that administration of eel flour accelerates the healing process
of the fracture showing 0.000, followed by Post Hoc LSD to determine the test of significant differences between
groups. Conclusion: It was observed that with the increase in the dose of flour given to Wistar Albino rat fracture
healing process became faster. From the present study it was evident that consumption of eel flour can accelerate the
process of fracture healing. But there is need for further testing on humans as an effort to test the safety of the dose.
