N-acetylaspartate (NAA)/choline (Cho) was the most studied metabolite ratio. Lower NAA/Cho ratio in basal ganglia and thalamus was associated with adverse motor, cognitive, and language outcomes, and worse global neurodevelopment. Lower NAA/Cho ratio in white matter was associated with cognitive impairment. However, some associations came from single studies or were discordant among studies. The quality of included studies was low. 1H-MRS could be a promising tool for early diagnosis of neurodevelopmental impairment. However, further studies of good quality are needed to define the relationship between metabolite ratios and neurodevelopment.Animal care professionals can experience adverse psychological outcomes due to their work, therefore research exploring supporting resilience in this population is needed. This study investigated the capacity of the Stress Shield Model (SSM) to explain relationships between individual, interpersonal, and organisational factors with outcomes in resilience (resilience, growth, and job satisfaction) in animal care professionals. Empowerment was hypothesised to mediate these relationships. Australian and New Zealand animal care professionals (N = 393) completed an online survey measuring conscientiousness, coping, team and leader relationships, job demands, organisational resources, empowerment, growth, resilience, and job satisfaction. Results indicated that SSM can partially explain relationships between individual, interpersonal, and organisational factors and outcomes in resilience, and empowerment partially mediated the effect of organisational resources on growth. click here Problem-approach coping positively predicted resilience and growth; conversely, emotion-avoidant coping negatively predicted these outcomes. Conscientiousness positively predicted resilience and negatively predicted job satisfaction. Team relationships positively predicted growth and resilience, while leader-member relationships positively predicted job satisfaction. Organisational resources positively predicted resilience, growth, and job satisfaction, conversely, job demands predicted reductions across these outcomes. Findings indicate supporting resilience in animal care professionals requires fostering individual, interpersonal, and organisational resources.As a consequence of anthropogenic climate change, marine species on continental shelves around the world are rapidly shifting deeper and poleward. However, whether these shifts deeper and poleward will allow species to access more, less, or equivalent amounts of continental shelf area and associated critical habitats remains unclear. By examining the proportion of seabed area at a range of depths for each large marine ecosystem (LME), we found that shelf area declined monotonically for 19% of LMEs examined. However, the majority exhibited a greater proportion of shelf area in mid-depths or across several depth ranges. By comparing continental shelf area across 2° latitudinal bands, we found that all coastlines exhibit multiple instances of shelf area expansion and contraction, which have the potential to promote or restrict poleward movement of marine species. Along most coastlines, overall shelf habitat increases or exhibits no significant change moving towards the poles. The exception is the Southern West Pacific, which experiences an overall loss of area with increasing latitude. Changes in continental shelf area availability across latitudes and depths are likely to affect the number of species local ecosystems can support. These geometric analyses help identify regions of conservation priority and ecological communities most likely to face attrition or expansion due to variations in available area.
Hereditary tyrosinemia type 1 is a rare metabolic condition associated with an increased risk of hepatocellular carcinoma. Nitisinone (2-[2-nitro-4-trifluoromethylbenzoyl]-1,3-cyclohexanedione, NTBC) treatment has reduced but not eliminated the risk. The delayed initiation of nitisinone treatment, and persistently abnormal α1-fetoprotein (AFP) levels are recognized to be risk factors for late-onset hepatocellular carcinoma. We report three children diagnosed and treated with nitisinone since infancy who developed hepatocellular carcinoma despite long-term normalization of AFP.

A retrospective review of all patients with tyrosinemia on nitisinone managed at our center was undertaken. Patient demographics, age at diagnosis, duration of therapy, timing of AFP normalization, and radiographic imaging findings were noted.

Three patients at our center with tyrosinemia type 1 developed hepatocellular carcinoma 9-13 years after diagnosis despite long-term nitisinone therapy and normalization of AFP. Two patients developed new nodules on imaging with an elevation of AFP leading to the diagnosis and subsequent liver transplant. The third patient proceeded with liver transplant because of a very nodular liver and increasing splenomegaly despite normal AFP and no change in surveillance gadoxetate magnetic resonance imaging. Early hepatocellular carcinoma was found in her liver explant. All three patients were cirrhotic at diagnosis.

Patients with hereditary tyrosinemia type 1, especially those already cirrhotic at diagnosis, remain at high risk of developing hepatocellular carcinoma despite long-term nitisinone therapy and AFP normalization, and warrant close monitoring and surveillance.

Patient-derived induced pluripotent stem cells (iPSCs) are materials that can be used for autologous stem cell therapy. We screened mtDNA mutations in iPSCs and iPSC-derived neuronal cells from patients with Alzheimer's disease (AD). Also, we investigated whether the mutations could affect mitochondrial function and deposition of β-amyloid (Aβ) in differentiated neuronal cells.

mtDNA mutations were measured and compared among iPSCs and iPSC-derived neuronal cells. The selected iPSCs carrying mtDNA mutations were subcloned, and then their growth rate and neuronal differentiation pattern were analyzed. The differentiated cells were measured for mitochondrial respiration and membrane potential, as well as deposition of Aβ.

Most iPSCs from subjects with AD harbored ≥1 mtDNA mutations, and the number of mutations was significantly higher than that from umbilical cord blood. About 35% and 40% of mutations in iPSCs were shared with isogenic iPSCs and their differentiated neuronal precursor cells, respectively, with similar or different heteroplasmy. Furthermore, the mutations in clonal iPSCs were stable during extended culture and neuronal differentiation. Finally, mtDNA mutations could induce a growth advantage with higher viability and proliferation, lower mitochondrial respiration and membrane potential, as well as increased Aβ deposition.

This study demonstrates that mtDNA mutations in patients with AD could lead to mitochondrial dysfunction and accelerated Aβ deposition. Therefore, early screening for mtDNA mutations in iPSC lines would be essential for developing autologous cell therapy or drug screening for patients with AD.

We aim to describe the determinants of very low birth weight (VLBW) in India and compare it with the determinants of LBW based on the National Family Health Survey - 4 (NHFS-4) Methods Data from the NFHS-4 on birthweight and other socio-demographic characteristics for the youngest child born in the family during the five years preceding the survey were used. Data of 147,762 infant-mother pairs were included. Multiple logistic regression models were employed to delineate the independent predictors of VLBW (birth weight less then 1500 g) or LBW (birth weight 1500-2499 g). Results Of the 147,762 children included in the study, VLBW and LBW were observed in 1.2% and 15.8% of children, respectively. The odds of VLBW were higher in female children (aOR 1.36, 95% CI 1.15-1.60), among mothers aged 13-19 years (aOR 1.58, 95% CI 1.22-2.07), mothers with severe or moderate anaemia (aOR 1.61, 95% CI 1.34-1.94), mothers without recommended antenatal care (aOR 1.47, 95% CI 1.31-1.90), maternal height less than 150 cm (aOR 1.54, 95% CI 1.29-1.85) and among mothers with multiple pregnancy (aOR 21.34, 95% CI 14.70-30.96) in comparison to their corresponding counterparts. In addition to the variables associated with VLBW, educational status of mothers (no education; aOR 1.08, 95% CI 1.02-1.15 and primary education; aOR 1.16, 95% CI 1.08-1.25), caste of the children (scheduled tribe; aOR 1.13, 95% CI 1.03-1.24), and wealthiness of the family (poorest wealth quintiles; aOR 1.11, 95% CI 1.03-1.19) were associated with LBW. Conclusions Interventions targeting improvements in antenatal care access, maternal health, and nutritional status may reduce the number of VLBW infants. Social determinants of LBW require further detailed study to understand the high propensity of low birth-weight phenotypes in the disadvantaged communities in India.
Cancer cachexia and tumor burden predict efficacies of programmed cell death-1 (PD-1)/programmed death-ligand 1 (PD-L1) inhibitors and chemotherapy or pembrolizumab in non-small cell lung cancer (NSCLC). There are no predictive models that simultaneously assess cancer cachexia and tumor burden.

In the present retrospective study, we reviewed the medical records of patients with advanced NSCLC who received cancer immunotherapy as first-line systemic therapy. Clinical immune predictive scores were defined according to multivariate analysis of progression-free survival (PFS) and overall survival (OS).

A total of 157 patients were included in the present study (75 treated with PD-1/PD-L1 inhibitors + chemotherapy; 82, pembrolizumab monotherapy). Multivariate analysis for PFS revealed that PD-L1 tumor proportion scores <50%, a total target lesion diameter ≥76 mm, and cancer cachexia were independently associated with poor PFS. Multivariate analysis for OS revealed that ≥4 metastases and cancer cachexia were significantly associated with poor OS. In the immune predictive model, the median PFS was 21.7months in the low-risk group (N=41); 7.6 in the medium-risk group (N=64); and 3.0 in the high-risk group (N=47). The median OS were not reached, 22.4 and 9.1months respectively. Our immune predictive model was significantly associated with PFS (p < 0.001) and OS (p < 0.001).

We proposed the immune predictive model, including tumor burden and cancer cachexia, which may predict the efficacy and survival outcome of first-line immunotherapy in advanced NSCLC.
