X-linked retinoschisis (XLRS) is an inherited retinal condition that leads to schisis of the retina. In the past, treatment trials for XLRS have generally used OCT monitoring of the schitic cavities as the primary structural outcome measure and best corrected visual acuity as the primary functional outcome. Here, we report two cases of genetically confirmed XLRS with marked fluctuations in OCT morphology in the absence of treatment. Given this demonstration of spontaneous fluctuation in retinal structure on OCT in XLRS we suggest that alternative measures of retinal function should be used in future therapeutic trials in XLRS.The effects of the temporary increase of organic loading rate (OLR) combined with the simultaneous decrease of hydraulic retention time (HRT) on the stability of a pilot scale dry anaerobic digester were investigated. The separately collected organic fraction of municipal solid waste in mesophilic conditions (T = 40°C) was treated. The objective of this study was to verify whether it is possible to feed the digester for short periods, about three consecutive weeks, with higher OLRs and lower HRTs than those considered optimal without generating process failure or long-term instability. Starting from stable operation at a daily OLR of 10.0 kg of total volatile solids (TVS) for digester volume and an HRT of 23 d, the reactor was fed with an OLR of 10.8, 11.7 and 12.5 kg TVS m-3 d-1 corresponding to an HRT of 21, 19 and 18 d, respectively. It was observed that after using an OLR of 10.8 and 11.7 kg TVS m-3 d-1 for 3 weeks with satisfying results, it was possible to restore stable operating conditions at an OLR of 10.0 kg TVS m-3 d-1 in a short time. Otherwise, after using an OLR of 12.5 kg TVS m-3 d-1 the anaerobic digestion was deeply unbalanced and quickly failed. In this latter case, however, it was possible to fully recover and restore the stable conditions of the process within two months.
To determine the incidence of bacteriuria, urinary tract infections (UTI), and significant extravasation of contrast on initial postoperative pericatheter retrograde urethrogram (pcRUG) after bulbar urethroplasty in relation to duration of urethral catheterization (DUC) of three weeks versus two weeks after surgery.

Retrospective chart review of 100 bulbar urethroplasty patients between January 2015 and November 2015 were compared with 50 prospective bulbar urethroplasty patients from June 2017 to February 2018 operated at the same university hospital. All patients in the retrospective cohort had catheter removal three weeks after surgery, while patients in the prospective cohort had catheter removal two weeks after surgery. Patient groups were compared using
-test and Fischer's exact test.

There was a higher incidence of UTI in patients with a DUC of three weeks after open urethroplasty compared to patients with two weeks DUC (
 = 0.03). Occurrence of extravasation on initial pcRUG or asymptomatic bacteruria did not differ between the two groups.

The findings in this study suggest that a DUC of two weeks may be more favorable compared to a DUC of three weeks.

Discrepancies between patient reports during clinical evaluations and self-reported suicide ideation are of vital importance. We study the agreement in passive suicidal ideation between reports made by clinicians and patients' self-reports.

Wish of death in 648 outpatients was assessed by attending clinicians. Within 24 h after clinical evaluation, patients completed a self-report questionnaire in which they were asked whether they had no desire to live. We used cluster analysis to determine the clinical profile of a population of patients according to the concordance between reports made by clinicians and self-reported information.

A low level of agreement (kappa = 0.072) was found between clinicians and patients, as 56.4% (
 = 366) of clinician reports classified as containing no death-related ideas although on self-report the patient did state that they had no desire to live. In this group containing discrepancies between the two reports, two clusters were found to have shared characteristics femaleve suicidal ideation.Most patients in whom the clinician underestimated the risk of suicide were women.Our results suggest that clinicians require adequate documentation of suicidal risk assessment to identify the high-risk population.Variants of the Diaphanous-Related Formin 1 (DIAPH-1) gene have recently been reported causing inherited macrothrombocytopenia. The essential/"diagnostic" characteristics associated with the disorder are emerging; however, robust and complete criteria are not established. Here, we report the first cases of DIAPH1-related disorder in Australia caused by the autosomal dominant gain-of-function DIAPH1 R1213X variant formed by truncation of the protein within the diaphanous auto-regulatory domain (DAD) with loss of regulatory motifs responsible for autoinhibitory interactions within the DIAPH1 protein. We affirm phenotypic changes induced by the DIAPH1 R1213X variant to include macrothrombocytopenia, early-onset progressive sensorineural hearing loss, and mild asymptomatic neutropenia. High-resolution microscopy confirms perturbations of cytoskeletal dynamics caused by the DIAPH1 variant and we extend the repertoire of changes generated by this variant to include alteration of procoagulant platelet formation and possible dental anomalies.Atypical Usher syndrome (USH) is poorly defined with a broad clinical spectrum. Here, we characterize the clinical phenotype of disease caused by variants in CEP78, CEP250, ARSG, and ABHD12.Chart review evaluating demographic, clinical, imaging, and genetic findings of 19 patients from 18 families with a clinical diagnosis of retinal disease and confirmed disease-causing variants in CEP78, CEP250, ARSG, or ABHD12.CEP78-related disease included sensorineural hearing loss (SNHL) in 6/7 patients and demonstrated a broad phenotypic spectrum including vascular attenuation, pallor of the optic disc, intraretinal pigment, retinal pigment epithelium mottling, areas of mid-peripheral hypo-autofluorescence, outer retinal atrophy, mild pigmentary changes in the macula, foveal hypo-autofluorescence, and granularity of the ellipsoid zone. Nonsense and frameshift variants in CEP250 showed mild retinal disease with progressive, non-congenital SNHL. ARSG variants resulted in a characteristic pericentral pattern of hypo-autofluorescence with one patient reporting non-congenital SNHL. ABHD12-related disease showed rod-cone dystrophy with macular involvement, early and severe decreased best corrected visual acuity, and non-congenital SNHL ranging from unreported to severe.This study serves to expand the clinical phenotypes of atypical USH. Given the variable findings, atypical USH should be considered in patients with peripheral and macular retinal disease even without the typical RP phenotype especially when SNHL is noted. Additionally, genetic screening may be useful in patients who have clinical symptoms and retinal findings even in the absence of known SNHL given the variability of atypical USH.While the role of platelets in cardiovascular diseases among the general population has been widely reported, evidence is inconsistent regarding the association between platelet indices with hypertension in pregnant women. In this study, we explored the associations between platelet parameters before 20 gestational weeks, an understudied period, with hypertensive disorders of pregnancy (HDP), including preeclampsia/eclampsia (PEEC) and gestational hypertension (GH). Based on the Born in Guangzhou Cohort Study, 12053 singleton pregnant women with platelet parameters, including platelet count (PC), mean platelet volume (MPV), plateletcrit (PCT), and platelet distribution width (PDW) measured at 14-19 gestational weeks were included. Conventional multivariable adjustment and propensity score analysis were used to control for confounders. The restricted cubic spline showed that the risk of PEEC increased linearly for PC, and non-linearly for PCT. For GH, the risk increased linearly for PC, MPV, and PCT, and non-linearly for PDW. When these indices were categorized into quintiles, women with higher PC and PCT were associated with increased risk of both PEEC and GH. Women with MPV exceeding the second quintile (≥ 8.8 fL) had a greater risk for GH, but not for PEEC. When HDP was classified into two groups (early- vs late-onset) based on the occurrence time, significant associations persisted for early-onset PEEC, early-onset GH, and late-onset GH. In conclusion, increased PC and PCT before 20 weeks of gestation were both associated with higher risk of PEEC and GH, while elevated MPV was only linked to GH.The aim was to assess neurological complications in children with an invasive neurological disease by dengue virus (DENV) and the time to resolve symptoms after hospital discharge. A prospective study was conducted at a referral hospital for infectious diseases in Brazil between March 2014 and July 2019. All children hospitalized with neurologic manifestations and DENV RNA detected by real-time reverse transcription-polymerase chain reaction (RT-qPCR) in cerebrospinal fluid (CSF) were followed up until complete resolution of neurological complications. On average, they were followed up for 16 months. Among 56 DENV-positive children, 39% had some neurologic complications after hospital discharge and found that 19.6% were discharged with anticonvulsants due to seizures, 10.7% developed motor complications (e.g. read more muscle weakness, paresis, ataxia, and walking disability), 5.4% had headaches, and 14.3% had sleep disorders. Among the 56 children, only three had a clinical diagnosis of dengue because the symptoms are nonspecific and 35% showed no change in cerebrospinal fluid (CSF). The average time to resolve complications was 5.9 months (ranging from 1 m to 32 m). These results should alert physicians to the difficulties of a clinical diagnosis of an infection that causes neurological complications after discharge in a significant number of children. RT-qPCR's etiological diagnosis of DENV infection enabled better clinical follow-up for early intervention in children with neurological complications.In the clinic, the supply of platelets is frequently insufficient to meet transfusion needs. To address this issue, many scientists have established the derivation of functional platelets from CD34+ cells or human pluripotent stem cells (PSCs). However, the yield of platelets is still far below what is required. Here we found that the plant hormone abscisic acid (ABA) could increase the generation of megakaryocytes (MKs) and platelets from human induced PSCs (hiPSCs). During platelet derivation, ABA treatment promoted the generation of CD34+/CD45+ HPCs and CD41+ MKs on day 14 and then increased CD41+/CD42b+ MKs and platelets on day 19. Moreover, we found ABA-mediated activation of Akt and ERK1/2 signal pathway through receptors LANCL2 and GRP78 in a PKA-dependent manner on CD34+/CD45+ cells. In conclusion, our data suggest that ABA treatment can promote CD34+/CD45+ HPC proliferation and CD41+ MK differentiation.
