Neurocognitive Functions After 6-Month Buprenorphine (Naloxone)-Based Opioid Agonist Maintenance Treatment: A Controlled Prospective Study.

BACKGROUND: Medications for opioid use disorder (OUD) may influence neurocognitive functions. Inadequate power, confounders, and practice effects limit the validity of the existing research. We examined the change in cognitive functions in patients with OUD at 6-month buprenorphine (naloxone) posttreatment and compared the cognitive performance of the buprenorphine-treated group with control subjects. METHODS: We recruited 498 patients with OUD within a week of initiating buprenorphine. Assessments were done twice-at baseline and 6 months. Those abstinent from illicit opioids and adherent to treatment (n = 199) underwent follow-up assessments. Ninety-eight non-substance-using control subjects were recruited from the community. The neurocognitive assessments comprised the Wisconsin Card Sorting Test, Iowa Gambling Task, Trail-Making Tests A and B (TMT-A and TMT-B), and verbal and visual N-Back Test. We controlled for potential effect modifiers. RESULTS: Twenty-five of the 32 test parameters significantly improved with 6 months of buprenorphine treatment; 20 parameters withstood corrections for multiple comparisons (P < 0.001). The improved test domains spread across cognitive tests: Wisconsin Card Sorting Test (perseverative errors and response, categories completed, conceptual responses), TMTs (time to complete), verbal and visual N-Back Tests (hits, omission, and total errors). After treatment, OUD (vs control subjects) had less perseverative response and error (P < 0.001) and higher conceptual response (P = 0.004) and took lesser time to complete TMT-A (P < 0.001) and TMT-B (P = 0.005). The baseline neurocognitive functions did not differ between those who retained and those who discontinued the treatment. CONCLUSION: Cognitive functions improve in patients with OUD on buprenorphine. This improvement is unlikely to be accounted for by the practice effect, selective attrition, and potential confounders.

Global models and predictions of plant diversity based on advanced machine learning techniques.

Despite the paramount role of plant diversity for ecosystem functioning, biogeochemical cycles, and human welfare, knowledge of its global distribution is still incomplete, hampering basic research and biodiversity conservation. Here, we used machine learning (random forests, extreme gradient boosting, and neural networks) and conventional statistical methods (generalized linear models and generalized additive models) to test environment-related hypotheses of broad-scale vascular plant diversity gradients and to model and predict species richness and phylogenetic richness worldwide. To this end, we used 830 regional plant inventories including c. 300 000 species and predictors of past and present environmental conditions. Machine learning showed a superior performance, explaining up to 80.9% of species richness and 83.3% of phylogenetic richness, illustrating the great potential of such techniques for disentangling complex and interacting associations between the environment and plant diversity. Current climate and environmental heterogeneity emerged as the primary drivers, while past environmental conditions left only small but detectable imprints on plant diversity. Finally, we combined predictions from multiple modeling techniques (ensemble predictions) to reveal global patterns and centers of plant diversity at multiple resolutions down to 7774 km2 . Our predictive maps provide accurate estimates of global plant diversity available at grain sizes relevant for conservation and macroecology.

Adhesions Detection and Staging Classification for Preoperative Assessment of Difficult Laparoscopic Cholecystectomies: A Prospective Case-Control Study.

Background: Laparoscopic cholecystectomy (LC) is the treatment of choice for cholelithiasis; however, there are procedural difficulties in determining preoperative detection of a difficult LC. The current methods using clinical and sonographic variables to identify difficult LCs have limitations to identify gallbladder adhesions which form the most common cause. We present a new method of evaluation using acoustic radiation force impulse (ARFI)-based virtual touch imaging (VTI) for the detection and classification of these patients. Methods: Fifty consecutive patients of cholelithiasis were evaluated preoperatively using conventional scoring system (CSS) and by new adhesion detection and staging (ADS) system, and patients were classified into three classes (I-III) with class I being easy, II and III being moderate-to-high difficulty LCs. Peroperative classification was done based on the difficulty level during surgery after visualization of gallbladder adhesions. The sensitivity, specificity, and area under the curves (AUCs) of both systems were compared. Results: Out of 50 patients, 72% and 54% of patients were in class I by CSS and ADS classification, while 28% and 46% were in class II and III, respectively, and were labeled as difficult LC cases; differences being two classifications were statistically significant (P = 0.02). Sensitivity, specificity, negative predictive value, and accuracy for ADS were 91%, 100%, 93.1%, and 96.0%, and for CSS, 60.9%, 100%, 75%, and 82% with AUCs of 1.0 and 0.63, respectively. Conclusion: ARFI-based VTI accurately detects gallbladder adhesions and can determine the difficult cases of LCs preoperatively using ADS classification and shows higher accuracy than CSS classification, which results in lower operative time and risk of complications.

Neural alterations in working memory of mild-moderate TBI: An fMRI study in Malaysia.

Working memory (WM) encompasses crucial cognitive processes or abilities to retain and manipulate temporary information for immediate execution of complex cognitive tasks in daily functioning such as reasoning and decision-making. The WM of individuals sustaining traumatic brain injury (TBI) was commonly compromised, especially in the domain of WM. The current study investigated the brain responses of WM in a group of participants with mild-moderate TBI compared to their healthy counterparts employing functional magnetic resonance imaging. All consented participants (healthy: n = 26 and TBI: n = 15) performed two variations of the n-back WM task with four load conditions (0-, 1-, 2-, and 3-back). The respective within-group effects showed a right hemisphere-dominance activation and slower reaction in performance for the TBI group. Random-effects analysis revealed activation difference between the two groups in the right occipital lobe in the guided n-back with cues, and in the bilateral occipital lobe, superior parietal region, and cingulate cortices in the n-back without cues. The left middle frontal gyrus was implicated in the load-dependent processing of WM in both groups. Further group analysis identified that the notable activation changes in the frontal gyri and anterior cingulate cortex are according to low and high loads. Though relatively smaller in scale, this study was eminent as it clarified the neural alterations in WM in the mild-moderate TBI group compared to healthy controls. It confirmed the robustness of the phenomenon in TBI with the reproducibility of the results in a heterogeneous non-Western sample.

A tetrapeptide class of biased analgesics from an Australian fungus targets the µ-opioid receptor.

An Australian estuarine isolate of Penicillium sp. MST-MF667 yielded 3 tetrapeptides named the bilaids with an unusual alternating LDLD chirality. Given their resemblance to known short peptide opioid agonists, we elucidated that they were weak (Ki low micromolar) µ-opioid agonists, which led to the design of bilorphin, a potent and selective µ-opioid receptor (MOPr) agonist (Ki 1.1 nM). In sharp contrast to all-natural product opioid peptides that efficaciously recruit ß-arrestin, bilorphin is G protein biased, weakly phosphorylating the MOPr and marginally recruiting ß-arrestin, with no receptor internalization. Importantly, bilorphin exhibits a similar G protein bias to oliceridine, a small nonpeptide with improved overdose safety. Molecular dynamics simulations of bilorphin and the strongly arrestin-biased endomorphin-2 with the MOPr indicate distinct receptor interactions and receptor conformations that could underlie their large differences in bias. Whereas bilorphin is systemically inactive, a glycosylated analog, bilactorphin, is orally active with similar in vivo potency to morphine. Bilorphin is both a unique molecular tool that enhances understanding of MOPr biased signaling and a promising lead in the development of next generation analgesics.

Biomediated synthesis, characterization, and biological applications of nickel oxide nanoparticles derived from Toona ciliata, Ficus carica and Pinus roxburghii.

Biomediated ecofriendly method for the synthesis of nickel oxide nanoparticles using plants extracts (Toona ciliata, Ficus carica and Pinus roxburghii) has been reported. The nanoparticles so obtained were characterized by various techniques such as ultraviolet-visible, powder X-ray diffraction, Fourier transform infrared spectroscopy, attenuated total reflectance spectroscopy, scanning electron microscopy, transmission electron microscopy, energy dispersive X-ray spectroscopy, thermogravimetric analysis and fluorescence spectroscopy. Formation of nickel oxide nanoparticles was confirmed by Fourier transform infrared spectroscopy and X-ray diffraction where the former technique ascertains the formation of bond between nickel and oxygen. The nickel oxide nanoparticles were found to be crystalline cubic face centered and show intense photoluminescence emission at 416, 414 and 413 nm, respectively. The antibacterial activity was studied against gram positive and gram negative bacterial species by agar well diffusion method. The nickel oxide nanoparticles show better activity against some bacterial strains with reference to the standard drugs Ciprofloxacin and Gentamicin. The anthelmintic activity against Pheretima posthuma of nanomaterials obtained from Pinus roxburghii was found to be greater than that derived from Toona ciliata and Ficus carica using the standard drug Albendazole. This method takes the advantage of the sustainable and economic approach for the synthesis of metal oxide nanoparticles.

A validated preoperative score for predicting 30-day readmission after 1-2 level elective posterior lumbar fusion.

PURPOSE: To develop a model to predict 30-day readmission rates in elective 1-2 level posterior lumbar spine fusion (PSF) patients. METHODS: In this retrospective case control study, patients were identified in the State Inpatient Database using ICD-9 codes. Data were queried for 30-day readmission, as well as demographic and surgical data. Patients were randomly assigned to either the derivation or the validation cohort. Stepwise multivariate analysis was conducted on the derivation cohort to predict 30-day readmission. Readmission after posterior spinal fusion (RAPSF) score was created by including variables with odds ratio (OR) > 1.1 and p < 0.01; value assigned to each variable was based on the OR and calibrated to 100. Linear regression was performed between readmission rate and RAPSF score to test correlation in both cohorts. RESULTS: There were 92,262 and 90,257 patients in the derivation and validation cohorts. Thirty-day readmission rates were 10.9% and 11.1%, respectively. Variables in RAPSF included: age, female gender, race, insurance, anterior approach, cerebrovascular disease, chronic pulmonary disease, congestive heart failure, diabetes, hemiplegia/paraplegia, rheumatic disease, drug abuse, electrolyte disorder, osteoporosis, depression, obesity, and morbid obesity. Linear regression between readmission rate and RAPSF fits the derivation cohort and validation cohort with an adjusted r2 of 0.92 and 0.94, respectively, and a coefficient of 0.011 (p < 0.001) in both cohorts. CONCLUSION: The RAPSF can accurately predict readmission rates in PSF patients and may be used to guide an evidence-based approach to preoperative optimization and risk adjustment within alternative payment models for elective spine surgery. LEVEL OF EVIDENCE: 3. These slides can be retrieved under Electronic Supplementary Material.

Outpatient total elbow arthroplasty: 90-day outcomes.

BACKGROUND: Interest in outpatient arthroplasty has grown in response to increasing emphasis on the efficient delivery of safe, high-quality medical care. This study evaluated 90-day episode-of-care complications after outpatient total elbow arthroplasty (TEA). MATERIALS AND METHODS: We retrospectively evaluated 28 patients discharged the same day after primary TEA for 90-day episode-of-care complications, reoperations, and readmissions. Postoperative complications and elbow range of motion measurements were recorded and evaluated at the latest follow-up. All patients were contacted and given a satisfaction survey to assess their outpatient experience. Univariate logistic regression was performed for each risk factor to evaluate the risk for major and minor complications. Statistical significance was set as P < .05. RESULTS: Final follow-up data were available for 28 patients at an average of 14 months. Major complications within 90 days of surgery occurred in 7.1% of patients, ulnar nerve paresthesias occurred in 42.8% of patients, and minor wound problems occurred in 39.2% of patients. Five reoperations occurred after the 90-day postoperative period. All ulnar paresthesias and minor wound complications had resolved by the latest follow-up. Univariate regression analysis revealed a significant correlation between smoking and minor wound complications (P = .038). The satisfaction survey had an 85.7% response rate, with 91.7% of patients stating they were happy they went home the same day, and 95.8% feeling more confident and in control of their lives. CONCLUSIONS: The risk profile of carefully selected patients undergoing same-day discharge after TEA is acceptable when combined with close follow-up.

Caregiver coping with the mentally ill: a qualitative study.

BACKGROUND: Mental illness is a disease that affects millions of people every year. It not only causes stress to the mentally ill patients, but also for the family members who provide them the care. The family caregivers, therefore need some form of coping strategies in dealing with their mentally ill family members. AIMS: This qualitative study aims at identifying and analysing the coping strategies adopted by the family caregivers in dealing with their mentally ill family members. METHOD: A total of 15 family caregivers from the state of Kedah, Malaysia participated in the face-to-face semi structured interview. RESULTS: The study findings identified an array of coping strategies used by the family caregivers, including religious coping, emotional coping, acceptance, becoming engaged in leisure activities, and the use of traditional healing to help them cope with their mentally ill members. Suggestions and conclusions: Study suggests that the family caregivers should engage themselves in social support groups to learn about and obtain the positive coping strategies used by other caregivers who have similar experiences in caring for the mentally ill. Study also suggests that they should get appropriate training from the mental health professionals in order to enhance the caregivers' coping skills.

Distal femur nonunion patients can expect good outcomes.

The purpose of this study is to describe our experience with distal femur nonunions and to report on the functional recovery of patients treated for these injuries. Twenty-two patients with an established distal femur nonunion were identified and followed prospectively. Results were compared with a control group consisting of 18 similar patients who had sustained an acute distal femur fracture. Compared with acute fracture patients, patients with a nonunion were more likely to have had an open fracture at initial injury (p = 0.02) and required a longer time to heal after final surgery (p = 0.054). No demographic variables were found to be predictive of complications, Short Musculoskeletal Functional Assessment scores, or time to union. These results show that patients with a distal femoral nonunion can expect to attain similar ultimate outcomes to patients receiving treatment for an acute distal femur fracture. Unlike the development of nonunions following other types of fracture, such as the hip, distal femur nonunions do not portend poor functional outcomes as long as bone union is achieved.

Neurocognitive Dysfunctions in People with Concurrent Cannabis Use and Opioid Dependence: A Cross-Sectional, Controlled Study.

Cannabis and opioid co-dependence is independently associated with cognitive impairments. We examined neurocognitive dysfunctions in people with concurrent opioid dependence with cannabis dependence (OD+CD) or cannabis use (OD+CU) compared to those with only opioid dependence (OD) and healthy controls (HC). We selected adult participants, any sex, who met the diagnosis of OD (N = 268), OD+CU (N = 58), and OD + CD (N = 115). We recruited 68 education-matched HC. We administeredStandard progressive matrices (SPM), Wisconsin card sorting test (WCST), Iowa gambling task (IGT), Trail making tests A and B (TMT), and verbal and visual working memory 1-, 2-backtests. 496 (97.5%) were men, and 13 (2.5%) were women. In WCST, OD and OD+CD had significantly higher non-perseverative errors than HC. OD+CD group completed significantly lesser categories than HC. In verbal working memory 2-back, HC scored significantly fewer errors than OD and OD +CD. All patient groups, OD, OD+CU, and OD+CD, scored higher commission errors than HC in visual working memory 1-back. OD and OD+CD scored higher commission and total errors than the controls. OD+CU showed lesser error score than HC in TMT B. Cannabis and opioid co-dependence contribute to cognitive impairments, especially in working memory and executive functions.

A comparison between intensive and conventional cabergoline treatment of newly diagnosed patients with macroprolactinoma.

CONTEXT: Intensive treatment with cabergoline may lead to earlier reduction in prolactin and tumour volume in comparison to conventional schedule. OBJECTIVE: To compare the efficacy and safety of two different dosing schedules of cabergoline in patients with macroprolactinoma. DESIGN: Prospective, randomized trial in drug naive patients assigned to conventional (4 weekly escalation by 0·5 mg per week, group A) or intensive (weekly increase by 1 mg per week followed by 4 weekly escalation, group B) treatment with cabergoline. OUTCOME MEASURE: The duration required to achieve normoprolactinemia and tumour shrinkage of >50% as a composite end-point. RESULTS: 38 patients (19 in each group) completed the study with a mean follow-up of 64·3 ± 24·9 weeks. More subjects (22%) achieved the composite end-point in group B (18/19) as compared to the group A (14/19) (P = 0·18). The duration of cabergoline treatment required to achieve the composite end-point was 13·1 ± 9·5 weeks vs 19·3 ± 15·7 weeks (P = 0·34) in the group A and B, respectively. A reduction in prolactin of ≥90% by the fourth week of cabergoline therapy predicted subsequent normalization of prolactin (AUC 0·78; P = 0·04). A further increase in cabergoline dosage after normalization of prolactin in patients with tumour reduction of <50%, led to further tumour shrinkage by 31·2% in an additional 26·3% of patients. CONCLUSIONS: Intensive treatment with cabergoline is not superior to the conventional recommended dosage schedule in respect to the time necessary to achieve normoprolactinemia and ≥50% tumour shrinkage. CLINICAL TRIAL REGISTRY: NCT 01143584.

Longitudinal study of influenza molecular viral shedding in Hutterite communities.

BACKGROUND: The nature of influenza viral shedding during naturally acquired infection is not well understood. METHODS: A cohort study was conducted in Hutterite colonies in Alberta, Canada. Flocked nasal swabs were collected during 3 influenza seasons (2007-2008 to 2009-2010) from both symptomatic and asymptomatic individuals infected with influenza. Samples were tested by real-time reverse-transcription polymerase chain reaction for influenza A and influenza B, and the viral load (VL) was determined for influenza A positive samples. RESULTS: Eight hundred thirty-nine participants were included in the cohort; 25% (208) tested positive for influenza viruses. They experienced 238 episodes of viral shedding, of which 23 (10%) were not accompanied by symptoms. For seasonal and pandemic H1N1, VL peaked at or before onset of acute respiratory infection. For H3N2, VL peaked 2 days after the onset of acute respiratory infection, which corresponded to peaks in systemic and respiratory symptom scores. Although the duration of shedding was shorter for asymptomatic participants, the peak level of VL shedding was similar to that of symptomatic participants. Viral loads for children and adults revealed similar patterns. CONCLUSIONS: Molecular viral shedding values follow symptom scores, but timing of peak VL varies by subtype. Asymptomatic infections are infrequent.

The Impact of Counseling on the Dignity of Older People: Protocol for a Mixed Methods Study.

BACKGROUND: Psychological counseling is perceived as a treatment that could significantly improve older individuals' psychological and behavioral functioning. There is a dearth of information on the impact of psychological counseling on preserving dignity and facilitating good aging among older people in Singapore. OBJECTIVE: The objectives of this study are as follows: (1) to assess advance care planning among older people and their perception of life and health, end of life, and end-of-life care; (2) to explore older people's accessibility and receptiveness toward counseling; (3) elucidate older people's perspectives on counseling and its impact on emotional management and decision-making; (4) to assess older people's competencies in emotional management; and (5) to propose an intervention model for enhancing older people's well-being and dignity through psychological counseling in Singapore. METHODS: A mixed method study design involving quantitative and qualitative methods will be used. Older individuals receiving some form of preventive, primary, or long-term care in the community through voluntary welfare organizations from the senior activity centers located in eastern Singapore participated in the qualitative phase. Six older individuals from each senior activity center have been enrolled for the interview phase to explore 6 components: the Advanced Care Planning (ACP) booklet, Trait Meta Mood Scale (TMMS), accessibility and receptiveness toward counseling, and emotional management and decision-making. The ACP, an instrument designed to assess advanced care planning among older individuals, and the TMMS, an instrument developed to measure meta-mood experience and emotional management, were used in the quantitative phase among 100 participants. The data will be analyzed thematically using NVivo version 12, whereas descriptive statistics and a 2-tailed, 1-sample t test will be conducted in SPSS (version 25; IBM Corp) for empirical data analyses. RESULTS: The qualitative phase, which involves a semistructured interview, has been completed among 20 older individuals aged 66-86 years. Thematic analysis of the data is still ongoing. Meanwhile, the quantitative phase commenced on March 22, 2022, with 100 participants providing signed informed consent to participate in the study. The study is expected to be completed by March 2023. CONCLUSIONS: The mixed methods study will document the current awareness of ACP, accessibility and receptiveness toward counseling, and the potential use of psychological counseling in enhancing well-being and dignity among older people in Singapore. The research findings will benefit policy makers in their decision-making when attempting to mitigate the potential barriers to seeking counseling assistance among older people.

Pyrrolidine based chiral organocatalyst for efficient asymmetric Michael addition of cyclic ketones to ß-nitrostyrenes.

An efficient asymmetric Michael addition of cyclic ketones to ß-nitrostyrenes using secondary diamine as an organocatalyst derived from l-proline and (R)-α-methylbenzyl amine has been described. This pyrrolidine based catalyst 1 was found to be very effective to synthesize various γ-nitrocarbonyl compounds in good yield (up to 81%) with excellent stereoselectivity (up to >99:1 dr and >99% ee).

A Qualitative Analysis of the Coping Strategies of Female Victimisation After Separation.

Victims of high-risk domestic violence in Malaysia return to their husbands if they lack the necessary support to face life challenges, especially after separation. Violence against women is part of the violation of human rights. Therefore, several action strategies are essential to counteract the various pressures of the social injustice they have endured. This qualitative study identifies how victims of domestic violence use coping strategies to face various challenges and pressures after deciding to break up with their spouse. In-depth interviews using purposive sampling and snowball techniques were conducted on 15 female respondents in Penang, Malaysia. Actions including filling in time, positive thinking, seeking formal services assistance, religious approaches, and sharing problems with informal systems successfully reduced the stress and concerns of victims of domestic violence. Enhancing and empowering domestic violence victims about their rights is vital for them to exit the abusive cycle. It is hoped that by understanding their rights as a person, they will be able to resort to better social support systems to overcome their current challenges to better social functioning. Hence, social workers must continuously provide the source of support, including empowering/allowing victims to continuously aware of their rights, which are the most fundamental elements of professional social work practice.

Alteration in the Functional Organization of the Default Mode Network Following Closed Non-severe Traumatic Brain Injury.

The debilitating effect of traumatic brain injury (TBI) extends years after the initial injury and hampers the recovery process and quality of life. In this study, we explore the functional reorganization of the default mode network (DMN) of those affected with non-severe TBI. Traumatic brain injury (TBI) is a wide-spectrum disease that has heterogeneous effects on its victims and impacts everyday functioning. The functional disruption of the default mode network (DMN) after TBI has been established, but its link to causal effective connectivity remains to be explored. This study investigated the differences in the DMN between healthy participants and mild and moderate TBI, in terms of functional and effective connectivity using resting-state functional magnetic resonance imaging (fMRI). Nineteen non-severe TBI (mean age 30.84 ± 14.56) and twenty-two healthy (HC; mean age 27.23 ± 6.32) participants were recruited for this study. Resting-state fMRI data were obtained at the subacute phase (mean days 40.63 ± 10.14) and analyzed for functional activation and connectivity, independent component analysis, and effective connectivity within and between the DMN. Neuropsychological tests were also performed to assess the cognitive and memory domains. Compared to the HC, the TBI group exhibited lower activation in the thalamus, as well as significant functional hypoconnectivity between DMN and LN. Within the DMN nodes, decreased activations were detected in the left inferior parietal lobule, precuneus, and right superior frontal gyrus. Altered effective connectivities were also observed in the TBI group and were linked to the diminished activation in the left parietal region and precuneus. With regard to intra-DMN connectivity within the TBI group, positive correlations were found in verbal and visual memory with the language network, while a negative correlation was found in the cognitive domain with the visual network. Our results suggested that aberrant activities and functional connectivities within the DMN and with other RSNs were accompanied by the altered effective connectivities in the TBI group. These alterations were associated with impaired cognitive and memory domains in the TBI group, in particular within the language domain. These findings may provide insight for future TBI observational and interventional research.

Disruption of white matter integrity and its relationship with cognitive function in non-severe traumatic brain injury.

Background: Impairment in cognitive function is a recognized outcome of traumatic brain injury (TBI). However, the degree of impairment has variable relationship with TBI severity and time post injury. The underlying pathology is often due to diffuse axonal injury that has been found even in mild TBI. In this study, we examine the state of white matter putative connectivity in patients with non-severe TBI in the subacute phase, i.e., within 10 weeks of injury and determine its relationship with neuropsychological scores. Methods: We conducted a case-control prospective study involving 11 male adult patients with non-severe TBI and an age-matched control group of 11 adult male volunteers. Diffusion MRI scanning and neuropsychological tests were administered within 10 weeks post injury. The difference in fractional anisotropy (FA) values between the patient and control groups was examined using tract-based spatial statistics. The FA values that were significantly different between patients and controls were then correlated with neuropsychological tests in the patient group. Results: Several clusters with peak voxels of significant FA reductions (p < 0.05) in the white matter skeleton were seen in patients compared to the control group. These clusters were located in the superior fronto-occipital fasciculus, superior longitudinal fasciculus, uncinate fasciculus, and cingulum, as well as white matter fibers in the area of genu of corpus callosum, anterior corona radiata, superior corona radiata, anterior thalamic radiation and part of inferior frontal gyrus. Mean global FA magnitude correlated significantly with MAVLT immediate recall scores while matrix reasoning scores correlated positively with FA values in the area of right superior fronto-occipital fasciculus and left anterior corona radiata. Conclusion: The non-severe TBI patients had abnormally reduced FA values in multiple regions compared to controls that correlated with several measures of executive function during the sub-acute phase of TBI.

Demographic Dividend in the Age of Neoliberal Capitalism: An Analysis of Employment and Employability in India.

After examining the concept of demographic dividend and in-depth analysis of the changing demographic profile of Indian population in a comparative framework, in this study it has been argued that the transformation of demographic potential into demographic dividend is predicated on the premise that India adopts state sponsored social-economic policy regime for public health and education for its youth to acquire skills which will be required in the twenty-first century and adopts macroeconomic policies which ensures optimal use of human resources. Otherwise demographic dividend will be a myth and a mirage.
