Creative females have larger white matter structures: Evidence from a large sample study

The importance of brain connectivity for creativity has been theoretically suggested and empirically demonstrated. Studies have shown sex differences in creativity measured by divergent thinking (CMDT) as well as sex differences in the structural correlates of CMDT. However, the relationships between regional white matter volume (rWMV) and CMDT and associated sex differences have never been directly investigated. In addition, structural studies have shown poor replicability and inaccuracy of multiple comparisons over the whole brain. To address these issues, we used the data from a large sample of healthy young adults (776 males and 560 females; mean age: 20.8 years, SD = 0.8). We investigated the relationship between CMDT and WMV using the newest version of voxel‐based morphometry (VBM). We corrected for multiple comparisons over whole brain using the permutation‐based method, which is known to be quite accurate and robust. Significant positive correlations between rWMV and CMDT scores were observed in widespread areas below the neocortex specifically in females. These associations with CMDT were not observed in analyses of fractional anisotropy using diffusion tensor imaging. Using rigorous methods, our findings further supported the importance of brain connectivity for creativity as well as its female‐specific association.

Increased functional connectivity between the default mode and salience networks in unmedicated adults with obsessive‐compulsive disorder

Deficits in attention have been implicated in Obsessive‐Compulsive Disorder (OCD), yet their neurobiological bases are poorly understood. In unmedicated adults with OCD (n = 30) and healthy controls (n = 32), they used resting state functional connectivity MRI (rs‐fcMRI) to examine functional connectivity between two neural networks associated with attentional processes: the default mode network (DMN) and the salience network (SN). They then used path analyses to examine putative relationships across three variables of interest: DMN‐SN connectivity, attention, and OCD symptoms. In the OCD compared with healthy control participants, there was significantly reduced inverse connectivity between the anterior medial prefrontal cortex (amPFC) and the anterior insular cortex, regions within the DMN and SN, respectively. In OCD, reduced inverse DMN‐SN connectivity was associated with both increased OCD symptom severity and decreased sustained attention. Path analyses were consistent with a potential mechanistic explanation: OCD symptoms are associated with an imbalance in DMN‐SN networks that subserve attentional processes and this effect of OCD on DMN‐SN connectivity is associated with decreased sustained attention. This work builds upon a growing literature suggesting that reduced inverse DMN‐SN connectivity may represent a trans‐diagnostic marker of attentional processes and suggests a potential mechanistic account of the relationship between OCD and attention. Reduced inverse DMN‐SN connectivity may be an important target for treatment development to improve attention in individuals with OCD. Hum Brain Mapp 38:678–687, 2017. © 2016 Wiley Periodicals, Inc.
The future of pre-exposure prophylaxis (PrEP) for human immunodeficiency virus (HIV) infection

ABSTRACT Introduction: People at high risk for HIV acquisition should be offered pre-exposure prophylaxis (PrEP). Tenofovir disoproxil fumarate (TDF)/emtricitabine (FTC) is currently the only medication recommended for pre-exposure prophylaxis (PrEP) by the Centers for Disease Control and Prevention (CDC) in people at high risk for HIV acquisition. This article will review medications currently under investigation and the future landscape of PrEP therapy. Areas covered: This article will review clinical trials that have investigated nontraditional regimens of TDF/FTC, antiretroviral agents from different drug classes such as integrase strand transfer inhibitors (INSTI), nucleoside reverse transcriptase inhibitors (NRTI), and non-nucleoside reverse transcriptase inhibitors (NNRTI) as potential PrEP therapies. Expert commentary: Currently, there are several investigational drugs in the pipeline for PrEP against HIV infection. Increased utilization of PrEP therapy depends on provider identification of people at high risk for HIV transmission. Advances in PrEP development will expand options and access for people and reduce the risk of HIV acquisition.
Bifid mandibular condyle with tempromandibular joint ankylosis - a pooled data analysis.

BACKGROUND AND OBJECTIVES Bifid mandibular condyle (BMC) with associated temporomandibular joint ankylosis (TMJA) is extremely rare with only sixteen cases reported worldwide. This article presents the largest case series with 12 patients of BMC with TMJA with treatment results in an attempt to elucidate the morphological pattern in this rare condition. MATERIALS AND METHOD Retrospective examination of Computed Tomograms (CT) over a period of 9 years revealed that 12 cases had BMC with TMJA. Demographical, Clinical, CT features and treatment results of these were analyzed. Patients were grouped according to sides of involvement and orientation of condyles. Data of 12 Indian cases were noted and pooled from existing literature from India and analysis performed using statistical software. Descriptive statistics and one way anova were used to find association. RESULTS The male: female ratio was 1:1. Twenty three cases were post-traumatic and one postinfectious. The etiology was sustained in childhood in all patients. The mean presenting age was 16.92 +/- 11.05 years. Of all the cases 66.7% presented with ipsilateral chin deviation. The mean mouth opening was 3.89 +/- 5.4 mm. Bilateral BMC was observed in 29% of cases and 87.5% of all cases had mesiolateral orientation. In general, ankylosed heads were mushroom shaped compared with non-ankylosed heads. The result of 1 year postoperative mouth opening was compared with treatment modalities used in this center. CONCLUSIONS This series attempts to elucidate patterns of ankylosis and CT morphology in BMC with associated TMJA. Also included are treatment results of BMC with TMJA. This case series is the largest presented and includes youngest case of TMJA with BMC reported so far in English literature.
ACUTE HEMATOPORPHYRIA: REPORT OF TWO CASES

The essential symptom of the condition that Gunther 1 designated "hematoporphyria" is the excretion of deeply pigmented urine the color of Burgundy wine containing an abnormal amount of hematoporphyrin. Two patients with the acute, idiopathic type of the disease were recently observed, and the histories are recorded in this article. REPORT OF CASES Case 1. —A white woman, aged 53, was admitted to the Los Angeles County General Hospital on Nov. 7, 1929. The illness had begun a week previously with nausea, vomiting and cramplike pain in the lower part of the abdomen. During two days before admission the pain had been severe, and vomiting had been continuous. The pain was diffuse over the abdomen and radiated to the thighs. She had had no similar attack previously, and had never used sedative drugs. There had been no known exposure to lead. So far as she knew, no member of her family
Abnormal task driven neural oscillations in multiple sclerosis: A visuomotor MEG study

Multiple sclerosis (MS) is a debilitating disease commonly attributed to degradation of white matter myelin. Symptoms include fatigue, as well as problems associated with vision and movement. Although areas of demyelination in white matter are observed routinely in patients undergoing MRI scans, such measures are often a poor predictor of disease severity. For this reason, it is instructive to measure associated changes in brain function. Widespread white‐matter demyelination may lead to delays of propagation of neuronal activity, and with its excellent temporal resolution, magnetoencephalography can be used to probe such delays in controlled conditions (e.g., during a task). In healthy subjects, responses to visuomotor tasks are well documented: in motor cortex, movement elicits a localised decrease in the power of beta band oscillations (event‐related beta desynchronisation) followed by an increase above baseline on movement cessation (post‐movement beta rebound (PMBR)). In visual cortex, visual stimulation generates increased gamma oscillations. In this study, we use a visuomotor paradigm to measure these responses in MS patients and compare them to age‐ and gender‐matched healthy controls. We show a significant increase in the time‐to‐peak of the PMBR in patients which correlates significantly with the symbol digit modalities test: a measure of information processing speed. A significant decrease in the amplitude of visual gamma oscillations in patients is also seen. These findings highlight the potential value of electrophysiological imaging in generating a new understanding of visual disturbances and abnormal motor control in MS patients.

Tuning face perception with electrical stimulation of the fusiform gyrus

The fusiform gyrus (FG) is an important node in the face processing network, but knowledge of its causal role in face perception is currently limited. Recent work demonstrated that high frequency stimulation applied to the FG distorts the perception of faces in human subjects (Parvizi et al. [ ]: J Neurosci 32:14915–14920). However, the timing of this process in the FG relative to stimulus onset and the spatial extent of FG's role in face perception are unknown. Here, we investigate the causal role of the FG in face perception by applying precise, event‐related electrical stimulation (ES) to higher order visual areas including the FG in six human subjects undergoing intracranial monitoring for epilepsy. We compared the effects of single brief (100 μs) electrical pulses to the FG and non‐face‐selective visual areas on the speed and accuracy of detecting distorted faces. Brief ES applied to face‐selective sites did not affect accuracy but significantly increased the reaction time (RT) of detecting face distortions. Importantly, RT was altered only when ES was applied 100ms after visual onset and in face‐selective but not place‐selective sites. Furthermore, ES applied to face‐selective areas decreased the amplitude of visual evoked potentials and high gamma power over this time window. Together, these results suggest that ES of face‐selective regions within a critical time window induces a delay in face perception. These findings support a temporally and spatially specific causal role of face‐selective areas and signify an important link between electrophysiology and behavior in face perception.

Monitoring proteolytic processing events by quantitative mass spectrometry

ABSTRACT Introduction: Protease activity plays a key role in a wide variety of biological processes including gene expression, protein turnover and development. misregulation of these proteins has been associated with many cancer types such as prostate, breast, and skin cancer. thus, the identification of protease substrates will provide key information to understand proteolysis-related pathologies. Areas covered: Proteomics-based methods to investigate proteolysis activity, focusing on substrate identification, protease specificity and their applications in systems biology are reviewed. Their quantification strategies, challenges and pitfalls are underlined and the biological implications of protease malfunction are highlighted. Expert commentary: Dysregulated protease activity is a hallmark for some disease pathologies such as cancer. Current biochemical approaches are low throughput and some are limited by the amount of sample required to obtain reliable results. Mass spectrometry based proteomics provides a suitable platform to investigate protease activity, providing information about substrate specificity and mapping cleavage sites.
Glycosylation profiling to evaluate glycoprotein immunogens against HIV-1

ABSTRACT Introduction: Much of the efforts to develop a vaccine against the human immunodeficiency virus (HIV) have focused on the design of recombinant mimics of the viral attachment glycoprotein (Env). The leading immunogens exhibit native-like antigenic properties and are being investigated for their ability to induce broadly neutralizing antibodies (bNAbs). Understanding the relative abundance of glycans at particular glycosylation sites on these immunogens is important as most bNAbs have evolved to recognize or evade the dense coat of glycans that masks much of the protein surface. Understanding the glycan structures on candidate immunogens enables triaging between native-like conformations and immunogens lacking key structural features as steric constraints limit glycan processing. The sensitivity of the processing state of a particular glycan to its structural environment has led to the need for quantitative glycan profiling and site-specific analysis to probe the structural integrity of immunogens. Areas covered: We review analytical methodologies for HIV immunogen evaluation and discuss how these studies have led to a greater understanding of the structural constraints that control the glycosylation state of the HIV attachment and fusion spike. Expert commentary: Total composition and site-specific glycosylation profiling are emerging as standard methods in the evaluation of Env-based immunogen candidates.
Relationship between white matter connectivity loss and cortical thinning in cerebral amyloid angiopathy

Patients with cerebral amyloid angiopathy (CAA) show loss of white matter connectivity and cortical thinning on MRI, primarily in posterior brain regions. Here we examined whether a potential causal relationship exists between these markers of subcortical and cortical brain injury by examining whether changes in cortical thickness progress in tandem with changes in their underlying connections. Thirty‐one patients with probable CAA with brain MRI at two time points were included (follow‐up time: 1.3 ± 0.4 years). Brain networks were reconstructed using diffusion MRI‐based fiber tractography. Of each network node, we calculated the change in fractional anisotropy‐weighted connectivity strength over time and the change in cortical thickness. The association between change in connectivity strength and cortical thickness was assessed with (hierarchical) linear regression models. Our results showed that decline in posterior network connectivity over time was strongly related to thinning of the occipital cortex (β = 0.65 (0.35–0.94), P < 0.001), but not to thinning of the other posterior or frontal cortices. However, at the level of individual network nodes, we found no association between connectivity strength and cortical thinning of the corresponding node (β = 0.009 ± 0.04, P = 0.80). Associations were independent of age, sex, and other brain MRI markers of CAA. To conclude, CAA patients with greater progressive loss of posterior white matter connectivity also have greater progression of occipital cortical thinning, but our results do not support a direct causal relationship between them. The association can be better explained by a shared underlying mechanism, which may form a potential target for future treatments. Hum Brain Mapp 38:3723–3731, 2017. © 2017 Wiley Periodicals, Inc.
Altered white matter microarchitecture in the cingulum bundle in women with primary dysmenorrhea: A tract‐based analysis study

Primary dysmenorrhea (PD), as characterized by painful menstrual cramps without organic causes, is associated with central sensitization and brain function changes. Previous studies showed the integrated role of the default mode network (DMN) in the pain connectome and its key contribution on how an individual perceives and copes with pain disorders. Here, we aimed to investigate whether the cingulum bundle connecting hub regions of the DMN was disrupted in young women with PD. Diffusion tensor imaging was obtained in 41 PD patients and 41 matched healthy controls (HC) during their periovulatory phase. The production of prostaglandins (PGs) was obtained in PD patients during their pain‐free and pain phases. As compared with HC, PD patients had similar scores of pain intensity, anxiety, and depression in their pain‐free phase. However, altered white matter properties mainly located in the posterior section of the cingulum bundle were observed in PD. Besides PGs being related to menstrual pain, a close relationship was found between the white matter properties of the cingulum bundle during the pain‐free phase and the severity of the menstrual pain in PD patients. Our study suggested that PD had trait changes of white matter integrities in the cingulum bundle that persisted beyond the time of menstruation. We inferred that altered anatomical connections may lead to less‐flexible communication within the DMN, and/or between the DMN and other pain‐related brain networks, which may result in the central susceptibility to develop chronic pain conditions in PD's later life.

Complementary Therapy Use Among Older Cancer Patients

purpose: The purpose of this study was to assess the use of complementary therapies among older cancer patients, to report patterns of use, and to understand who is more likely to use complementary therapies. description of study: A survey was conducted of 699 older cancer patients at 4 weeks and 6 weeks into cancer treatment. All participants were 64 years of age or older, had received a diagnosis of breast, colorectal, prostate, or lung cancer, and were recruited from community cancer treatment centers throughout Michigan. Measures of interest included self-reported physical symptoms, depressive symptomatology, optimism, spirituality, and use of conventional and complementary health services. results: Approximately 33% of older cancer patients reported using complementary therapies. These individuals were more likely to be women, to be breast cancer patients, and to have a higher level of education. The three most frequently used therapies were exercise, herbal therapy, and spiritual healing. Complementary therapy users were significantly more optimistic than nonusers. Also, there were significant differences between users and nonusers on types of physical symptoms experienced, but no differences on reported depressive symptomatology or spirituality. clinical implications: Oncology providers need to be aware that one third of their older patients are likely to supplement conventional care with complementary therapies. Therefore, providers should be knowledgeable about the safety and efficacy, in particular, of various exercise programs, herbal and vitamin therapies, and spiritual healing. It would be beneficial to develop a system within cancer centers by which patients could easily report on their use of complementary therapies, allowing providers to work in partnership with their patients.

Bone Mineral Density of Very Long-term Survivors After Childhood Liver Transplantation

Objectives: Liver transplant patients are at risk of osteopenia and fractures but limited information is available in long-term survivors after childhood transplantation. This study aimed to assess bone mineral density (BMD) of very long-term, >5 years, survivors after liver transplantation in childhood. Methods: Patients aged <18 years at transplant, having survived >5 years after transplant were potentially eligible but only those with ongoing review in our state were included. Dual-energy x-ray absorptiometry (DXA) was used to measure BMD. Patients aged <20 years had lumbar spine (LS) and total body (TB) measurements whereas those aged 20 years or more had LS and femoral neck but not TB. BMD z-scores for LS and TB, if available, were used in this study. BMD z-score ⩽−2.0 was considered reduced. Pre-pubertal children had radiologic bone age assessment. Results: Forty-two patients, 17 boys, participated of whom 64% had biliary atresia. Median age at transplant was 2.22 (range 0.38–14.25) years; time since transplant 10.10 (5.01–25.98) years; and age at DXA 14.64 (6.59–38.07) years. Mean BMD z-scores were LS −0.15 ± 1.07, and TB −0.76 ± 1.14, with no sex difference noted. Four (9.5%) patients had reduced LS BMD, and although ongoing steroid use was more frequent in these patients, other comorbidities were likely important. Age at transplant, time since transplant, height, weight, and body mass index at DXA did not predict LS BMD. Pathologic fractures occurred in 2 of 42 (5%) patients; all within 18 months of transplant. Conclusions: Very long-term survivors after childhood liver transplant have LS BMD within the normal range.
Structural connectivity differences in motor network between tremor‐dominant and nontremor Parkinson's disease

Motor phenotypes of Parkinson's disease (PD) are recognized to have different prognosis and therapeutic response, but the neural basis for this clinical heterogeneity remains largely unknown. The main aim of this study was to compare differences in structural connectivity metrics of the main motor network between tremor‐dominant and nontremor PD phenotypes (TD‐PD and NT‐PD, respectively) using probabilistic tractography‐based network analysis. A total of 63 PD patients (35 TD‐PD patients and 28 NT‐PD patients) and 30 healthy controls underwent a 3 T MRI. Next, probabilistic tractography‐based network analysis was performed to assess structural connectivity in cerebello‐thalamo‐basal ganglia‐cortical circuits, by measuring the connectivity indices of each tract and the efficiency of each node. Furthermore, dopamine transporter single‐photon emission computed tomography (DAT‐SPECT) with 123I‐ioflupane was used to assess dopaminergic striatal depletion in all PD patients. Both PD phenotypes showed nodal abnormalities in the substantia nigra, in agreement with DAT‐SPECT evaluation. In addition, NT‐PD patients displayed connectivity alterations in nigro‐pallidal and fronto‐striatal pathways, compared with both controls and TD‐PD patients, in which the same motor connections seemed to be relatively spared. Of note, in NT‐PD group, rigidity‐bradykinesia score correlated with fronto‐striatal connectivity abnormalities. These findings demonstrate that structural connectivity alterations occur in the cortico‐basal ganglia circuit of NT‐PD patients, but not in TD‐PD patients, suggesting that these anatomical differences may underlie different motor phenotypes of PD.
