We report here the optimal combinations of biological variables to reduce inter-experimental variance for all 11 parameters. We also rank each parameter by intra- and inter-experimental consistency. We expect these results to assist with design of experimental and analytical methods, and to support accuracy in simulations. Furthermore, although demonstrated on spinal motoneuron electrophysiology literature, our approach is applicable to biological data from all fields of neuroscience. This approach represents an important aid to experimental design, comparison of reported data, and reduction of unexplained variance in neuroscience data.Introduction An important gap within modern medicine is the lack of enough comparative effectiveness research of marketed medicines. Low-risk pragmatic randomized controlled trials (pRCTs) are those conducted resembling usual clinical practice that poses no or minimal incremental risk compared with normal clinical practice.Areas covered This review addresses one important hurdle in the conduct of low-risk pRCTs the need to seek participants' written informed consent.Expert opinion The CIOMS ethical guidelines consider that any research that (a) would not be feasible or practicable to carry out without the waiver or modification, (b) has important social value, and (c) poses no more than minimal risks to participants, and that is approved by the relevant research ethics committee, could be conducted without participants' consent. It is clear that these provisions are applicable to some low-risk RCTs. Recently a research on the EU-CTR registry showed that only 2% of all ongoing phase 4 RCTs could have fulfilled the CIOMS provisions following the investigators' assessment. The EU clinical trial regulation - and that of other jurisdictions - should be debated on the suitableness of the conduct with an alteration or waiver of participants' consent of those low-risk pRCTs that fulfill the three CIOMS provisions.Aim We report a series of orbital sarcoid in a south Indian patient population and their outcome.Materials & Methods Retrospective interventional case series.Results Eleven out of 144cases of biopsy-proven sarcoidosis had orbital involvement. The mean age was 50.64 ± 9.52years and was more commonly seen in women (90.91%). Unilateral presentation with right orbit involvement was more common. Bilateral lacrimal gland enlargement (4cases), inferior orbital mass presenting as proptosis (4cases), preseptal mass above upper eyelid (2cases) and orbital mass encasing the globe (1case) were the different types of orbital presentation. All cases had a dry eye and a negative mantoux test. CT thorax was abnormal in 7cases (63.61%). Biopsy in all cases showed noncaseating granulomatous inflammation. Oral steroids were the standard mode of treatment and none of the cases had recurrences.Conclusions Orbital sarcoidosis is seen in a high TB endemic country like India and is definitely underreported.Persistent cognitive, affective, and motor symptoms have been associated with sports-related concussions including several neurophysiological changes in the primary motor cortex. In particular, previous research has provided some evidence of altered latencies of the corticomotor pathway and altered motor neuroplasticity. However, to date no studies have assessed these neurophysiological metrics in a common group of athletes across different phases of injury and recovery. Here corticomotor latencies and neuroplasticity were assessed in collegiate athletes with or without a history of prior concussion across two different phases of injury either in an acute-state of concussion (within two weeks of injury) or in a chronic-state of concussion (more than 1 year after injury). Corticomotor latencies were determined by measuring the motor evoked potential (MEP) onset time and motor neuroplasticity was assessed by measuring MEP amplitudes following application of anodal transcranial direct current stimulation (tDCS) over the primary motor cortex (M1). We found that concussed athletes had slower corticomotor latencies than non-concussed athletes, and corticomotor latency was also positively correlated with the number of prior concussions. MEDICA16 In contrast, there was no evidence of altered motor neuroplasticity in athletes regardless of concussion history. These findings suggest concussions may lead to permanent changes in the corticospinal tract that are exacerbated by repeated injury.This study aimed to reduce maternal anxiety scores and heart rates, increase oxygen saturation linked to vaccination processes with Skin-to skin contact (SSC). The study is a prospective, multicenter, paired, randomized, controlled trial. This experimental study was conducted with a pretest-posttest control group. The study was carried out with 128 mothers of infants. A Sociodemographic Questionnaire, the State Anxiety Inventory and a pulse oximeter were used in the data collection. In the study, SSC began to be given to the infants in the intervention group five minutes before vaccination and the infant was left in SSC for an uninterrupted 15 minutes following the vaccination. The maternal anxiety scores were noted before and after the vaccination process. The mothers' heart rates and oxygen saturation were monitored a total of three times. The anxiety scores of the intervention group decreased while oxygen saturation increased after the vaccination as compared to the control group. The heart rate decreased in the intervention group but increased in the control group. The study revealed that SSC reduced scores of maternal anxiety and heart rates and increased oxygen saturation during the vaccination process.Purpose Head and neck cancers (HNSCC) are routinely treated with radiotherapy; however, normal tissue toxicity remains a concern. Therefore, it is important to validate treatment modalities combining molecularly targeted agents with radiotherapy to improve the therapeutic ratio. The aim of this study was to assess the ability of the PARP inhibitor niraparib (MK-4827) alone, or in combination with cell cycle checkpoint abrogating drugs targeting Chk1 (MK-8776) or Wee1 (MK-1775), to radiosensitize HNSCCs in the context of HPV status.Materials and methods PARP1, PARP2, Chk1 or Wee1 shRNA constructs were analyzed from an in vivo shRNA screen of HNSCC xenografts comparing radiosensitization differences between HPV(+) and HPV(-) tumors. Radiosensitization by niraparib alone or in combination with MK-8776 or MK-1775 was assessed by clonogenic survival in HPV(-) and HPV(+) cells; and the role of p16 in determining response was explored. Relative expressions of DNA repair genes were compared by PCR array in HPV(+) and HPV(-) cells, and following siRNA-mediated knockdown of TRIP12 in HPV(-) cells.
