Risk of Congenital Anomalies with Dolutegravir-Based Anti-retroviral Regimens: A Systematic Review and Meta-analysis.

BACKGROUND AND OBJECTIVES: Dolutegravir has been used as a first-line anti-human immunodeficiency virus drug because of its better efficacy compared with other counterpart medicines. However, making a unanimous decision on its use during pregnancy has become difficult for stakeholders following congenital anomalies reported with its use. The objective of this systematic review and meta-analysis was to study the risk of congenital anomalies in newborns exposed to dolutegravir-based-regimens compared with those exposed to non-dolutegravir-based regimens during the antenatal period. METHODS: An extensive literature search was performed in MEDLINE (through PubMed), EMBASE, Cochrane Database of Systematic Reviews, Google Scholar, and ClinicalTrials.gov until 30 November, 2023. Studies reporting data on congenital anomalies following antenatal use of dolutegravir were included. Risk of bias for randomized controlled trials, non-randomized controlled trials, and observational studies was assessed using RoB2, ROBINS-I, and ROBINS-E tools, respectively. A meta-analysis was performed in 'RevMan 5.4.1' using a random-effects model. Heterogeneity was assessed by the 'Q' statistic and I2 value. A sensitivity analysis was performed for higher heterogeneity/high-risk studies. The study protocol was registered in PROSPERO [CRD42023446374] a priori. RESULTS: Of 26 eligible studies, 12 (six randomized controlled trials and six observational studies with a pooled sample of 32,617) were included in a meta-analysis and 14 in a qualitative synthesis only. The meta-analysis does not show a statistically significant difference in the risk of congenital anomalies between newborns exposed antenatally to dolutegravir-based regimen(s) and those exposed to non-dolutegravir-based regimens [risk ratio 1.10; 95% confidence interval 0.79-1.53; p = 0.59]. Heterogeneity was moderate (I2 = 47%). Pooled results for randomized controlled trials and observational studies separately and the sensitivity analysis for heterogeneity provided similar results. CONCLUSIONS: The risk of congenital anomalies was not significantly different between dolutegravir-based regimens and non-dolutegravir-based-regimens in newborns exposed during their antenatal period.

The Influence of Psoriasis on Type 2 Diabetes Mellitus Patient Profiles: A National Inpatient Sample Study.

Background: Psoriasis is believed to be a common comorbidity of type 2 diabetes mellitus (T2DM). Little is known on the impact psoriasis has on T2DM patients' disease profiles. Objective: To assess the impact psoriasis has on T2DM patients' demographics, comorbidities, and health care outcomes. Methods: We retrospectively analyzed the 2017 U.S. National Inpatient Sample (NIS) database. We utilized ICD-10 codes to determine T2DM and psoriasis patients along with associated comorbidities. Continuous variables were compared by independent-sample t-tests and categorical variables were compared via Pearson chi-square. All analysis were conducted in IBM SPSS 25. Results: Among 7,705,988 T2DM admissions, 0.67% of them had comorbid psoriasis. T2DM psoriasis patients (64.38; SD: 12.403) were, on average, younger (64.38 vs 66.73; P < .001) and white (78.7% vs 63.1%; P < .001) and had increased foot ulcers (4.2% vs 3.8%; P < .001), hyperglycemia (22.4% vs 21.0%; P < .001), retinopathy (22.4% vs 21.0%; P < .001), hypercoagulopathy (8.5% vs 6.9%; P < .001), and hypertension (72.5% vs 70.4%; P < .001) than T2DM patients without psoriasis. T2DM psoriasis patients spent more days in the hospital (5.49 vs 5.37; P < .001), had more concurrent diagnoses (19.05 vs 16.5; P < .001), less total charges ($60,596.71 vs $61,534.66; P = 0.010) and had less in-hospital deaths (2.0% vs 2.7%; P < .001) than T2DM patients without psoriasis. Conclusions: The presence of comorbid psoriasis significantly impacts T2DM patients' demographics, comorbidities, and health care outcomes. These findings underscore the importance of early disease monitoring, cross-specialty collaboration, and medication monitoring in order to guide individualized management strategies and optimize patient care.

Systemic Outcomes in Adults Undergoing Emergent Repair of Orbital Blowout Fractures.

Purpose: To analyze the association between emergent surgery status and systemic adverse outcomes in patients undergoing open orbital floor blowout fracture repair. Methods: This retrospective cohort analysis utilized the 2005-2018 National Surgery Quality Improvement Program (NSQIP) database. Current Procedural Terminology (CPT) codes were used to identify cases with open treatment of orbital floor blowout fractures (21385, 21386, 21387, 21390, 21395). Demographics, comorbidities, and complication incidences were compared between patients undergoing emergent surgery and those undergoing non-emergent orbital blowout fracture repair using chi-square analyses. The independent effect of preoperative emergent status on adverse outcomes was analyzed using binary logistic regression. Results: 1,146 (96.0%) non-emergent and 48 (4.0%) emergent orbital blowout fracture repairs were identified from 2005 to 2018. Chi-square analysis indicated patients undergoing emergent repairs had higher incidences of preoperative wound infection (8.3% vs. 2.3%; p = 0.029) and systemic sepsis (8.3% vs. 0.6%; p = 0.001). The emergent cohort had a higher proportion of patients with Hispanic ethnicity (p = 0.011). Unadjusted chi-square analysis indicated the emergent cohort had a higher incidence of prolonged length of stay (50.1% vs. 10.1%; p < 0.001). After adjusting for confounders, logistic regression analysis indicated emergent status was an independent risk factor for prolonged length of stay (OR 13.05; 95% CI 5.26-32.37; p < 0.001). Conclusion: Emergent surgery status is an important factor associated with increased odds of prolonged length of stay in patients undergoing open orbital blowout fracture repair.

Association Between Modified Frailty Index and Postoperative Outcomes of Cricopharyngeal Myotomy.

OBJECTIVE: The modified 5-item frailty index (mFI-5) is a comorbidity-based risk stratification tool previously validated in patients undergoing several surgical procedures. This study investigates the association between mFI-5 score and cricopharyngeal myotomy (CM) complications. STUDY DESIGN: Retrospective database review. SETTING: US hospitals. METHODS: The National Surgical Quality Improvement Program database was queried for patients who underwent CM between 2005 and 2018. mFI-5 score was determined by assigning 1 point for comorbidities including: diabetes mellitus, hypertension, congestive heart failure, chronic obstructive pulmonary disease, and dependent health status. Univariate and multivariable analyses were conducted to determine associations between mFI-5 score and postoperative complications. RESULTS: A total of 1075 patients undergoing CMs were queried and stratified into the following groups: mFI = 0 (n = 412 [38.3%]), mFI = 1 (n = 452 [42.0%]), and mFI ≥ 2 (n = 211 [19.6%]). Univariate analysis showed association between higher mFI-5 scores with older age, higher American Society of Anesthesiologists Classification class, obesity, smoking, dyspnea, and systemic sepsis. Higher mFI-5 was associated with a greater proportion of cumulative surgical complications, cumulative medical complications, pneumonia, myocardial infarction, cumulative morbidity, readmissions, unplanned readmissions, and reoperations. Multivariable analyses found associations between greater mFI-5 score and cumulative morbidity (odds ratio [OR] = 1.95, confidence interval [CI]: 1.29-2.96, P = .002), any surgical complication (OR = 1.80, CI: 1.15-2.79, P = .010), readmission (OR = 1.81, CI: 1.01-3.26, P = .047), and reoperations (OR = 1.96, CI: 1.04-3.68, P = .037). CONCLUSION: Evaluating mFI-5 can help assess the risk of postoperative complications for patients undergoing CM. LEVEL OF EVIDENCE: Level 4.

Gemini surfactants as next-generation drug carriers in cancer management.

INTRODUCTION: Gemini surfactants (GS) are an elite class of amphiphilic molecules that have shown up as a potential candidate in the field of drug delivery because of their exceptional physicochemical properties. They comprise two hydrophilic headgroups connected by an adaptable spacer and hydrophobic tails that has shown promising results in delivering different therapeutic agents to cancer cells at preclinical level. However further studies are in demand to unlock the full potential of GS in this field. AREAS COVERED: This review summarizes the new advancements in GS as drug carriers in cancer therapy, their capacity to overcome conventional shortcomings and the demand for innovative approaches in disease treatment. A detailed list of GS-based formulations along with a brief description on oligomeric surfactants have also been provided in this review. This article summarizes data from studies identified through literature database searches including PubMed and Google Scholar (2010-2023). EXPERT OPINION: There are major challenges that need to be addressed in this field which restrict their progression toward clinical phase. Further research can focus on developing a theranostic system that can provide simultaneous real-time monitoring along with treatment care. Nevertheless, ensuring the safety parameters of these nanocarriers followed by their regulatory approval is a time-consuming and expensive process. A collaborative approach between regulatory bodies, research institutions, and pharmaceutical companies can speed up the process in the upcoming years.

The Patient Population at Homeopathic Outpatient Clinics across India: A Clinical Data Collection Study.

BACKGROUND: Even though several initiatives have been undertaken in different locations worldwide to collect clinical data in homeopathy, it is important to further investigate these aspects in the context of health care in India. OBJECTIVE: The study aimed to gather and analyze patients' clinical data and to derive insights into homeopathic treatment using an internet-based software program for data storage, retrieval and repertorization. METHODS: A multi-center observational study was conducted across 14 homeopathy outpatient clinics in India that are affiliated with the Central Council for Research in Homoeopathy (CCRH). Patient symptoms and demographic details were documented anonymously, and prescriptions were guided by repertorial suggestions from the Vithoulkas Compass software. During follow-up visits, treatment outcome was also recorded using an online assessment form. A retrospective analysis of data on patients' demographics, follow-up visits, morbidity (International Classification of Diseases 11th Revision), rubrics used, prescribed medicines and the level of improvement was achieved using Microsoft Excel-generated pivot tables. RESULTS: Throughout the study duration of one year a total of 2,811 patients attended the 14 outpatient clinics, of whom 2,468 were new patients with a total of 2,172 initial homeopathic prescription entries. Across the study, there were 3,491 prescriptions and 1,628 follow-up consultations for 868 follow-up patients, all of which data were thoroughly analyzed. The highest frequency of patients was in the 20-49 age group, and a higher proportion of the patients overall was female. Musculoskeletal, dermatological and respiratory complaints were the most frequently reported. The rubrics "Desire for sweets" and "Desire for spices" emerged as the most commonly used in the repertorizations. Further, Sulphur stood out as the most commonly prescribed medicine overall. With homeopathic treatment, some degree of clinical improvement was reported in 86% of the follow-up cases. CONCLUSION: Homeopathy is prescribed in CCRH outpatient clinics for a wide range of ailments in people across India, with at least some clinical improvement noted in a high proportion of those patients. The large-scale systematic data collection in these clinics has provided clear insights into the use and clinical value of homeopathy in India, with the potential to build a substantive nationwide data inventory over time.

Smoking impacts outcomes in transcervical Zenker's diverticulectomy.

PURPOSE: There is sparse literature discussing the impact of smoking on postoperative outcomes following surgical treatment of Zenker's diverticulum. In this study, we seek to characterize differences in the management and outcomes of open Zenker's diverticulectomy based on patient smoking status. METHODS AND MATERIALS: This paper is a retrospective cohort review. The 2005-2018 American College of Surgeons National Surgical Quality Improvement (ACS-NSQIP) database was queried for patients undergoing open Zenker's diverticulectomy. Chi-square and multivariable logistic regression were performed to determine statistical associations between postoperative outcomes and smoking status. RESULTS: Of the 715 identified patients, 70 (9.8 %) were smokers and 645 (91.2 %) were non-smokers. Smokers were younger than non-smokers (mean 63.9 vs. 71.7 years, p < 0.001) and more likely to have a prolonged operative time (20.0 % vs. 11.6 %, p = 0.044). On multivariable regression analysis controlling for demographics and comorbidities, smokers had greater odds than non-smokers for developing overall postoperative complications (OR: 2.776, p = 0.013), surgical infections (OR: 3.194, p = 0.039), medical complications (OR: 3.563, p = 0.011), and medical infections (OR: 1.247, p = 0.016). Smokers also had greater odds for requiring ventilation/intubation (OR: 8.508, p = 0.025) and having a prolonged postoperative stay (OR: 2.425, p = 0.030). CONCLUSION: In a cohort of patients undergoing transcervical Zenker's diverticulectomy, smokers are at increased risk for overall complications, medical complications, medical infections, surgical infections, prolonged postoperative stay, and ventilation/intubation.

Association Between Modified Frailty Index and Postoperative Outcomes of Tracheostomies.

OBJECTIVE: The 5-item modified frailty index (mFI-5) has been used to stratify patients based on the risk of postoperative complications in several surgical procedures but has not yet been done in tracheostomies. This study investigates the association between the mFI-5 score and tracheostomy complications. STUDY DESIGN: Retrospective database review. SETTING: United States hospitals. METHODS: The National Surgical Quality Improvement Program database was queried for tracheostomy patients between 2005 and 2018. The mFI-5 was calculated for each patient by assigning 1 point for each of the following comorbidities: diabetes mellitus, hypertension, congestive heart failure, chronic obstructive pulmonary disease, and functionally dependent health status. Univariate and multivariable analyses were conducted to determine associations between the mFI-5 score and postoperative complications. RESULTS: A total of 4438 patients undergoing tracheostomies were queried and stratified into the following groups: mFI = 0 (N = 1741 [39.2%], mFI = 1 (N = 1720 [38.8%]), mFI = 2 (N = 726 [16.4%]), and mFI of 3 or higher (N = 251 [5.7%]). Univariate analysis showed that patients with higher mFI-5 scores had a greater proportion of smoking, dyspnea, obesity, steroid use, emergency cases, complications, reoperations, and mortality (P < .001). Multivariable analyses found associations between mFI-5 score and any complication (odds ratio [OR]: 1.49, 95% confidence interval [CI]: 1.03-2.16, P = .035), mortality (OR: 2.32, 95% CI: 1.15-4.68, P = .019), and any medical complication (OR: 2.75, 95% CI: 1.88-4.02, P < .001). CONCLUSION: This study suggests an association between the mFI-5 score and postoperative complications in tracheostomies. mFI-5 score can be used to stratify tracheostomy patients by operative risk.

The role of scoliosis on the comorbidity and demographics of neurofibromatosis type 1 patients: A retrospective analysis of the National Inpatient Sample database.

Neurofibromatosis type 1 (NF1) is the most common neurocutaneous syndrome in the United States, affecting every 1 in 3000 individuals. NF1 occurs due to non-functional mutations in the NF1 gene, which expresses neurofibromin, a protein involved in tumour suppression. As a result, NF1 typically presents with non-cancerous neoplasm masses called neurofibromas across the body. Out of all NF1 abnormalities, the most common skeletal abnormality seen in around 10%-30% of NF1 patients is scoliosis, an improver curvature of the spine. However, there is a lack of research on the effects of scoliosis on demographics and morbidities of NF1 patients. We performed a national analysis to investigate the complex relationship between NF1 and scoliosis on patients' demographics and comorbidities. We conducted a retrospective cross-sectional analysis of the 2017 US National Inpatient Sample database using univariable Chi-square analysis and multivariable binary logistic regression analysis to determine the interplay of NF1 and scoliosis on patients' demographics and comorbidities. Our query resulted in 4635 total NF1 patients, of which 475 (10.25%) had scoliosis and 4160 (89.75%) did not. Demographic analysis showed that NF1 patients with scoliosis were typically younger, female and white compared to NF1 patients without scoliosis. Comorbidity analysis showed that NF1 patients with scoliosis were more likely to develop malignant brain neoplasms, epilepsy, hydrocephalus, pigmentation disorders, hypothyroidism, diabetes with chronic complications and coagulopathy disorders. NF1 patients with scoliosis were less likely to develop congestive heart failure, pulmonary circulation disease, peripheral vascular disease, paralysis, chronic pulmonary disease, lymphoma and psychosis. NF1 patients with scoliosis were predominantly younger, female, white patients. The presence of scoliosis in NF1 patients increases the risks for certain brain neoplasms and disorders but serves a protective effect against some pulmonary and cardiac complications.

Association between levels of insulin-like growth factor-1 in serum and seminal plasma with fresh and frozen-thawed semen characteristics in Beetal bucks.

The aim of this study was to investigate the relationship between the levels of insulin-like growth factor-1 (IGF-1) in serum and seminal plasma and the characteristics of semen in Beetal bucks (Capra hircus). A total of 12 adult Beetal bucks were involved in the study, with each buck providing six ejaculates collected using a standard artificial vagina (n = 72 total). Only qualified semen samples (volume of 0.7 mL, a mass motility rating of 3+ or higher on a 0-+ scale, and individual progressive motility of 80% or more) divided into three fractions were processed for estimation of IGF-1 and other seminal parameters like motility, viability, acrosome integrity, sperm abnormality and superoxide dismutase (SOD) activity. The first and second fraction were diluted and extended with Optixcell extender (1:15 ratio). The first ejaculate fraction was processed for studying fresh semen parameters and the second fraction was cryopreserved for evaluating frozen semen parameters. French mini straws (0.25 mL) were used for semen filling, and polyvinyl alcohol powder of different colours was used for sealing the extended semen. The third fraction of each ejaculate was centrifuged at room temperature (1100 × g for 7 min) to separate the seminal plasma. Additionally, blood samples were taken from each buck on the same day as semen collection, resulting in a total of 36 blood samples. The results revealed a significant positive correlation (r = .4243; p < .05) between the concentration of IGF-1 in both serum and seminal plasma of the Beetal bucks. Furthermore, the concentration of IGF-1 in serum showed significant positive correlations with sperm viability (r = .554; p < .05), acrosome integrity (r = .527; p < .05), post-thaw sperm motility (r = .407; p < .01), post-thaw sperm viability (r = .426; p < .01) and post-thaw acrosome integrity (r = .333; p < .05). However, it had a significant negative correlation with SOD activity in fresh semen (r = -0.458; p < .01). Moreover, the concentration of IGF-1 in seminal plasma demonstrated significant positive correlations with individual progressive motility (r = .341; p < .05), sperm viability (r = .527; p < .05), acrosome integrity (r = .539; p < .05), sperm plasma membrane integrity (r = .464; p < .05), post-thaw sperm motility (r = .644; p < .01), post-thaw sperm viability (r = .643; p < .01), post-thaw acrosome integrity (r = .487; p < .01) and post-thaw sperm plasma membrane integrity (r = .521; p < .01). Additionally, it showed a significant negative correlation with SOD activity in both fresh semen (r = -0.714; p < .01) and frozen semen (r = -0.558; p < .01) of Beetal bucks. Based on these findings, IGF-1 in seminal plasma can be considered as a potential biomarker for the selection of bucks for breeding purposes.

Localisation of eloquent cortex using magnetoencephalography and its clinical implications.

OBJECTIVES: This study aimed to localise the eloquent cortex and measure evoked field (EF) parameters using magnetoencephalography in patients with epilepsy and tumours near the eloquent cortex. METHODS: A total of 41 patients (26 with drug-refractory epilepsy and 15 with tumours), with a mean age of 33 years, were recruited. Visual evoked field (VEF), auditory evoked field (AEF), sensory evoked field (SSEF), and motor-evoked field (MEF) latencies, amplitudes, and localisation were compared with those of a control population. Subgroup analyses were performed based on lobar involvement. Evoked Field parameters on the affected side were compared with those on the opposite side. The effect of distance from the lesion on nearby and distant evoked fields was evaluated. RESULTS: AEF and VEF amplitudes and latencies were reduced bilaterally (p < 0.05). Amplitude in the ipsilateral SSEF was reduced by 29.27% and 2.16% in the AEF group compared to the contralateral side (p = 0.02). In patients with temporal lobe lesions, the SSEF amplitude was reduced bilaterally (p < 0.02), and latency was prolonged compared with controls. The MEF amplitude was reduced and latency was prolonged in patients with frontal lobe lesions (p = 0.01). EF displacement was 32%, 57%, 21%, and 16% for AEF, MEF, VEF, and SSEF respectively. Patients in the epilepsy group had distant EF abnormalities. CONCLUSIONS: EF amplitude was reduced and latency was prolonged in the involved hemisphere. Distant EF amplitudes were more affected than latencies in epilepsy. Amplitude and distance from the lesion had negative correlation for all EF. EF changes indicated eloquent cortical displacement which may not be apparent on MRI.

Synthesis of a trinuclear zinc(II) cluster composed of [4.4.3.01,5]tridecane cages: a rapid detection and degradation probe for the chemical warfare agent simulant diethyl cyanophosphonate in protein-rich food products.

Diethyl cyanophosphonate (DCNP), a simulant of Tabun, is a common pollutant in pharmaceutical waste and poses a high risk to living organisms. Herein, we demonstrate a compartmental ligand-derived trinuclear zinc(II) cluster [Zn3(LH)2(CH3COO)2] as a probe for the selective detection and degradation of DCNP. It consists of two pentacoordinated Zn(II) [4.4.3.01,5]tridecane cages bridged through a hexacoordinated Zn(II) acetate unit. The structure of the cluster has been elucidated by spectrometric, spectroscopic, and single-crystal X-ray diffraction studies. The cluster shows a two-fold increased emission as compared to the compartmental ligand (at λexc = 370 nm and λem = 463 nm) due to the chelation-enhanced fluorescence effect and acts as a turn-off signal in the presence of DCNP. It can detect DCNP at nano levels up to 186 nM (LOD). The direct bond formation between DCNP and Zn(II) via the -CN group degrades it to inorganic phosphates. The mechanism of the interaction and degradation is supported by spectrofluorimetric experiments, NMR titration (1H and 31P), time of flight mass spectrometry and density functional theory calculations. The applicability of the probe has been further tested by the bio-imaging of zebrafish larvae, analysis of high-protein food products (meat and fish) and vapour phase detection by paper strips.

Resting-State Functional MRI/PET Profile as a Potential Alternative to Tri-Modality EEG-MR/PET Imaging: An Exploratory Study in Drug-Refractory Epilepsy.

Objective The study explores whether the epileptic networks associate with predetermined seizure onset zone (SOZ) identified from other modalities such as electroencephalogram/video electroencephalogram/structural MRI (EEG/VEEG/sMRI) and with the degree of resting-state functional MRI/positron emission tomography (RS-fMRI/PET) coupling. Here, we have analyzed the subgroup of patients who reported having a seizure on the day of scan as postictal cases and compared the findings with interictal cases (seizure-free interval). Methods We performed independent component analysis (ICA) on RS-fMRI and 20 ICA were hand-labeled as large scale, noise, downstream, and epilepsy networks (Epinets) based on their profile in spatial, time series, and power spectrum domains. We had a total of 43 cases, with 4 cases in the postictal group (100%). Of 39 cases, 14 cases did not yield any Epinet and 25 cases (61%) were analyzed for the final study. The analysis was done patient-wise and correlated with predetermined SOZ. Results The yield of finding Epinets on RS-fMRI is more during the postictal period than in the interictal period, although PET and RS-fMRI spatial, time series, and power spectral patterns were similar in both these subgroups. Overlaps between large-scale and downstream networks were noted, indicating that epilepsy propagation can involve large-scale cognition networks. Lateralization to SOZ was noted as blood oxygen level-dependent activation and correlated with sMRI/PET findings. Postoperative surgical failure cases showed residual Epinet profile. Conclusion RS-fMRI may be a viable option for trimodality imaging to obtain simultaneous physiological information at the functional network and metabolic level.

Multivariate associations between cognition and neighborhood geospatial characteristics in schizophrenia.

Cognitive impairment contributes to functional impairment in schizophrenia. Yet, little is known about how environmental characteristics are related to cognition in schizophrenia. By examining how cognition and the environment are intertwined, it may be possible to identify modifiable risk and protective factors that can improve cognitive outcomes in schizophrenia. We aimed to identify multivariate associations between cognition and three geospatial characteristics (built-space density, habitable green spaces, and public spaces for social interaction) within one's immediate neighborhood among individuals with schizophrenia. We recruited participants with schizophrenia from three sites - an urban metropolitan and two towns in southern India. We administered standard cognitive assessments and performed a principal axis factoring to identify episodic memory, cognitive control, and social inference-making factors for use in further analyses. We estimated geospatial characteristics of an individual's neighborhood, i.e., up to 1 km2 around the residence, by sourcing data from Google Earth. We performed unconditional and conditional (to examine the effect of clinical covariates) canonical correlation analyses to understand the multivariate relationship between cognition and geospatial characteristics. We analyzed data from 208 participants; the first canonical cognitive variate (higher social inference-making and poorer cognitive control) shared 24% of the variance (r = 0.49; P < 0.001) with the first geospatial variate (lower built density and poorer access to public spaces). Years of education, age at onset, and place of residence significantly modulated this relationship. We observe differential associations of the built environment with social and non-social cognition in schizophrenia, and highlight the clinical and demographic characteristics that shape these associations.

Characterisation of acylated anthocyanins from red cabbage, purple sweet potato, and Tradescantia pallida leaves as natural food colourants by HPLC-DAD-ESI(+)-QTOF-MS/MS and ESI(+)-MSn analysis.

Anthocyanins in red cabbage, sweet potato, and Tradescantia pallida leaves were characterised. A total of 18 non-, mono-, and diacylated cyanidins was identified in red cabbage by high performance liquid chromatography-diode array detection coupled to high-resolution and multi-stage mass spectrometry. Sweet potato leaves contained 16 different cyanidin- and peonidin glycosides being predominantly mono- and diacylated. In T. pallida leaves, the tetra-acylated anthocyanin tradescantin prevailed. The large proportion of acylated anthocyanins resulted in a superior thermal stability during heating of aqueous model solutions (pH 3.0) coloured with red cabbage and purple sweet potato extracts as compared to that of a commercial Hibiscus-based food dye. However, their stability was still outperformed by that of the most stable Tradescantia extract. Comparing vis spectra from pH 1-10, the latter had an additional, uncommon absorption maximum at approx. 585 nm at slightly acidic to neutral pH values, yielding intensely red to purple colours.

Growth trajectories for executive and social cognitive abilities in an Indian population sample: Impact of demographic and psychosocial determinants.

Cognitive abilities are markers of brain development and psychopathology. Abilities, across executive, and social domains need better characterization over development, including factors that influence developmental change. This study is based on the cVEDA [Consortium on Vulnerability to Externalizing Disorders and Addictions] study, an Indian population based developmental cohort. Verbal working memory, visuo-spatial working memory, response inhibition, set-shifting, and social cognition (faux pas recognition and emotion recognition) were cross-sectionally assessed in > 8000 individuals over the ages 6-23 years. There was adequate representation across sex, urban-rural background, psychosocial risk (psychopathology, childhood adversity and wealth index, i.e. socio-economic status). Quantile regression was used to model developmental change. Age-based trajectories were generated, along with examination of the impact of determinants (sex, childhood adversity, and wealth index). Development in both executive and social cognitive abilities continued into adulthood. Maturation and stabilization occurred in increasing order of complexity, from working memory to inhibitory control to cognitive flexibility. Age related change was more pronounced for low quantiles in response inhibition (ß∼4 versus  -1 versus -0.25 for lower quantiles). Wealth index had the largest influence on developmental change across cognitive abilities. Sex differences were prominent in response inhibition, set-shifting and emotion recognition. Childhood adversity had a negative influence on cognitive development. These findings add to the limited literature on patterns and determinants of cognitive development. They have implications for understanding developmental vulnerabilities in young persons, and the need for providing conducive socio-economic environments.

Engineered organotin(IV) and vanadium(V) derivatives with distinct coordination modes and luminescent properties for the efficient detection and quantification of permanganate ions.

The distinction in coordination modes of metal complexes leads to their versatile structural features and unique properties. Here, we report two tetradentate Schiff base ligands (H2L1 and H2L2) bearing N2O2 donor sets, tactically selected to provide distinct coordination modes with different metal ions. The ligands were utilized to synthesize their organotin(IV) (1-4) and vanadium(V) (5) derivatives. The synthesized compounds were characterized using elemental analysis, FT-IR spectroscopy, multi-nuclei NMR (1H, 13C, and 119Sn) spectroscopy, mass spectrometry, and single-crystal X-ray diffraction. The organotin(IV) derivatives (1-4) displayed hepta-coordination around both the Sn centres as they were achieved in their dimeric form. Contrariwise, the vanadium(V) compound (5) was isolated as a mononuclear entity exhibiting penta-coordinated geometry around the vanadium centre. The variation in the coordination modes was evident in their UV-vis and fluorescence spectra. The organotin(IV) compounds (1-4) exhibited a strong emission band centred at 468 nm when excited at a wavelength of 360 nm whereas the vanadium(V) (5) derivative displayed poor fluorogenic response. Compound 1 was further explored for the fluorogenic chemo-sensing of permanganate ions (MnO4-) amongst various anions by quenching response. A detailed investigation of the recognition of permanganate ions was accomplished by spectrofluorometric, spectroscopic (119Sn NMR), mass spectrometric, and computational studies.
