To evaluate the knowledge and experiences of healthcare workers in the management of neurometabolic disorders.
A cross-sectional study was carried out among the 132 participants of a continued medical education program conducted in the Department of Pediatrics at a tertiary-care teaching hospital. A questionnaire-based feedback form was circulated among the participants, and their responses were analyzed.
Ninety-three responses were analyzed. The most common pediatric illnesses identified were infections (91%), nutritional (91%), birth-related injuries (44.4%) and metabolic disorders (44.4%). Consanguinity (81.5%) and genetic heterogeneity (42.4%) were recognized as most important causes of neurometabolic disorders. Important steps identified for prevention were prenatal testing (65.6%) and newborn screening at birth (61%); while for improving the diagnosis were routine availability of metabolic investigations (65.3%) and screening at birth (46.6%). Most respondents (58.7%) expressed discomfort in managing a case with inherited metabolic defect due to a lack of knowledge (46.8%) and diagnostic facilities (44.6%). Despite access to testing in the majority, a high cost of testing was noticed for biochemical and genetic investigations. The majority of participants (73%) considered some of the inherited metabolic disorders as treatable. Dietary substitution (89.3%), enzyme replacement (69%), cofactor replacement (53.6%), gene therapy (35.7%) and regular dialysis (16.7%) were considered the treatment options.
In spite of growing awareness of inherited metabolic disorders, there are still gaps in knowledge among healthcare workers. It is challenging to diagnose and manage these disorders. Cost-reduction of diagnostic tests, routine newborn screening and increased educational activities are key challenges to be addressed.

Mild traumatic brain injury (mTBI) is the most common form of TBI (70-90%) with consequences of anxiety-like behavioral alterations in approximately 23% of mTBI cases. This study aimed to assess whether mTBI-induced anxiety-like behavior is a consequence of neurometabolic alterations. mTBI was induced using a weight drop model to simulate mild human brain injury in rodents. Based on injury induction and dosage of anesthesia, four animal groups were included in this study: (i) injury with anesthesia (IA); (ii) sham1 (injury only, IO); (iii) sham2 (only anesthesia, OA); and (iv) control rats. After mTBI, proton magnetic resonance spectroscopy (1 H-MRS) and neurobehavioral analysis were performed in these groups. At day 5, reduced taurine (Tau)/total creatine (tCr, creatine and phosphocreatine) levels in cortex were observed in the IA and IO groups relative to the control. These groups showed mTBI-induced anxiety-like behavior with normal cognition at day 5 post-injury. An anxiogenic effect of repeated dosage of anesthesia in OA rats was observed with normal Tau/tCr levels in rat cortex, which requires further examination. In conclusion, this mTBI model closely mimics human concussion injury with anxiety-like behavior and normal cognition. Reduced cortical Tau levels may provide a putative neurometabolic basis of anxiety-like behavior following mTBI.
