BACKGROUND: Usher syndrome 1 (USH1) is the most severe subtype of Usher syndrome characterized by severe sensorineural hearing impairment, retinitis pigmentosa, and vestibular areflexia. USH1 is usually induced by variants in MYO7A, a gene that encodes the myosin-VIIa protein. Myosin-VIIA is effectively involved in intracellular molecular traffic essential for the proper function of the cochlea, the retinal photoreceptors, and the retinal pigmented epithelial cells.
METHODS AND RESULTS: In this study, we report a new homozygous missense variant (NM_000260.4: c.1657 C > T p.(His553Tyr)) in MYO7A of a 28-year-old female with symptoms consistent with USH1. This variant, c.1657 C > T p.(His553Tyr) is positioned in the highly conserved myosin-VIIA motor domain. Previous studies showed that variants in this domain might disrupt the ability of the protein to bind to actin and thus cause the disorder.
CONCLUSIONS: Our findings contribute to our understanding of the phenotypic and mutational spectrum of USH1 associated with autosomal recessive MYO7A variants and emphasize the important role of molecular testing in accurately diagnosing this syndrome. More advanced research is required to understand the functional effect of the identified variant and the genotype-phonotype correlations of MYO7A-related Usher syndrome 1.

A method of treating a warm-blood vertebrate. The verebrate may be a human being or a lower animal. The treatment method involves administering to the vertebrate in need of such treatment a pharmaceutically effective amount of a salt of a halide-free glucosamine base and a therapeutic drug containing at least one acid functionality, e.g., a carbonyl moiety, a carboxyl moiety, a sulfoxide moiety, etc. Preferably, the salt is stabilized by coating it with at least one pharmaceutically acceptable polymer comprising a water-soluble, water-immiscible and/or water-swellable homopolymer and/or copolymer. Suitable polymers include carboxypolymethylene homopolymers and copolymers; polyethylene glycol homopolymers and copolymers, povidone homopolymers and copolymers; polyacrylic acid homopolymers and copolymers; polyacrylamide homopolymers and copolymers; polysaccharides; and mixtures of two or more of the foregoing polymers. The resultant coated halide-free glucosamine-therapeutic drug salt composition will be stable upon exposure to ambient temperature and/or the atmosphere. Suitable therapeutic drugs containing at least one acid functionality may be found in one or more of the following classes of therapeutic drugs. α- and β-Adrenergic Agonists; Narcotic and Non-Narcotic Analgesics; Anorexics; Antiallergics; Antianginals; Antiarrhythmics; Antiasthmatics; Antibiotics; Anti-coagulants; Anticonvulsants; Antidepressants; Antidiabetics; Antihistaminics; Anti-hypertensives; Nonsteroidal Anti-Inflammatories; Antimigraines; Antineoplastics; Antiparkinsonians; Antipsychotics; Antipyretics; Antispasmodics; Antithrombotics; Anti-ulceratives; Anxiolytics; Decongestants; Diuretics; Hepatoprotectants; Sedatives; and Vasodilators.
BACKGROUND: Bloodstream infections (BSI) are highly prevalent in hospitalized patients requiring intensive care. They are among the most serious infections and are highly associated with sepsis or septic shock, which can lead to prolonged hospital stays and high healthcare costs. This study aimed at establishing an easy-to-use nomogram for predicting the prognosis of patients with BSI.
METHODS: In retrospective study, records of patients with BSI admitted to the intensive care unit (ICU) over the period from Jan 1st 2016 to Dec 31st 2021 were included. We used data from two different China hospitals as development cohort and validation cohort respectively. The demographic and clinical data of patients were collected. Based on all baseline data, k-means algorithm was applied to discover the groups of BSI phenotypes with different prognostic outcomes, which was confirmed by Kaplan-Meier analysis and compared using log-rank tests. Univariate Cox regression analyses were used to estimate the risk of clusters. Random forest was used to identified discriminative predictors in clusters, which were utilized to construct nomogram based on multivariable logistic regression in the discovery cohort. For easy clinical applications, we developed a bloodstream infections clustering (BSIC) score according to the nomogram. The results were validated in the validation cohort over a similar period.
RESULTS: A total of 360 patients in the discovery cohort and 310 patients in the validation cohort were included in statistical analyses. Based on baseline variables, two distinct clusters with differing prognostic outcomes were identified in the discovery cohort. Population in cluster 1 was 211 with a ICU mortality of 17.1%, while population in cluster 2 was 149 with an ICU mortality of 41.6% (p < 0.001). The survival analysis also revealed a higher risk of death for cluster 2 when compared with cluster 1 (hazard ratio: 2.31 [95% CI, 1.53 to 3.51], p < 0.001), which was confirmed in validation cohort. Four independent predictors (vasoconstrictor use before BSI, mechanical ventilation (MV) before BSI, Deep vein catheterization (DVC) before BSI, and antibiotic use before BSI) were identified and used to develop a nomogram. The nomogram and BSIC score showed good discrimination with AUC of 0.96.
CONCLUSION: The developed score has potential applications in the identification of high-risk critically ill BSI patients.
"Green Dot" is a bystander intervention program that empowers students to actively question peer support for sexual violence (SV) and become change agents who play a significant role in preventing sexual violence. The purpose of this study is to evaluate the statewide application of Green Dot among high schools students. We hypothesize that students in high schools with Green Dot will over time report lower rates of SV compared with students in comparable high schools randomized not to have Green Dot. A high school based controlled intervention trial is being used to test the efficacy of Green Dot. Both panel and cohort survey methods will be used to provide baseline and prospective data on student's attitudes supporting SV, bystander behaviors and violence victimization and perpetration. In 13 Kentucky regions, 2 demographically comparable high schools were recruited to participate in Green Dot intervention either as the intervention or control site. Schools were randomly assigned to the intervention. Study Population includes all students in participating high schools invited to complete anonymous panel surveys beginning spring 2010 through 2014. This state-wide, population-based, multi-site controlled intervention trial provides an empirical test of a promising intervention, which, if proven effective, could result in the primary prevention of SV and a reduction in the health and academic consequences of SV.
BACKGROUND: Treatment of acute stroke, before a distinction can be made between ischemic and hemorrhagic types, is challenging. Whether very early blood-pressure control in the ambulance improves outcomes among patients with undifferentiated acute stroke is uncertain.
METHODS: We randomly assigned patients with suspected acute stroke that caused a motor deficit and with elevated systolic blood pressure (≥150 mm Hg), who were assessed in the ambulance within 2 hours after the onset of symptoms, to receive immediate treatment to lower the systolic blood pressure (target range, 130 to 140 mm Hg) (intervention group) or usual blood-pressure management (usual-care group). The primary efficacy outcome was functional status as assessed by the score on the modified Rankin scale (range, 0 [no symptoms] to 6 [death]) at 90 days after randomization. The primary safety outcome was any serious adverse event.
RESULTS: A total of 2404 patients (mean age, 70 years) in China underwent randomization and provided consent for the trial: 1205 in the intervention group and 1199 in the usual-care group. The median time between symptom onset and randomization was 61 minutes (interquartile range, 41 to 93), and the mean blood pressure at randomization was 178/98 mm Hg. Stroke was subsequently confirmed by imaging in 2240 patients, of whom 1041 (46.5%) had a hemorrhagic stroke. At the time of patients' arrival at the hospital, the mean systolic blood pressure in the intervention group was 159 mm Hg, as compared with 170 mm Hg in the usual-care group. Overall, there was no difference in functional outcome between the two groups (common odds ratio, 1.00; 95% confidence interval [CI], 0.87 to 1.15), and the incidence of serious adverse events was similar in the two groups. Prehospital reduction of blood pressure was associated with a decrease in the odds of a poor functional outcome among patients with hemorrhagic stroke (common odds ratio, 0.75; 95% CI, 0.60 to 0.92) but an increase among patients with cerebral ischemia (common odds ratio, 1.30; 95% CI, 1.06 to 1.60).
CONCLUSIONS: In this trial, prehospital blood-pressure reduction did not improve functional outcomes in a cohort of patients with undifferentiated acute stroke, of whom 46.5% subsequently received a diagnosis of hemorrhagic stroke.

The past century witnessed the evolution of growth hormone (GH) treatment from pituitary-derived GH, available for treatment of selected cases of GH deficiency (GHD), to recombinant human GH (rhGH), currently approved for several clinical disorders besides GHD. Treatment with rhGH has a proven efficacy in improving short stature in patients affected by GHD, alongside beneficial effects on metabolic and bone health. Long-term safety of rhGH treatment has been intensively investigated, providing reassuring results, especially in patients treated for isolated GHD. The use of rhGH in supraphysiological doses in conditions other than GHD and the intrinsic risk factors associated with certain clinical conditions prompt the need to prolong surveillance studies on rhGH safety. Finally, long-acting rhGH formulations are being introduced into the market, with the goal of increasing adherence and reducing treatment burden for patients on rhGH treatment. In this review, we will discuss indications, efficacy, and safety profile of treatment with rhGH in pediatric patients affected by GHD. We will also briefly discuss the newer formulation of rhGH.
FIELD: immunology, microbiology, genetic and protein engineering. SUBSTANCE: invention relates to immunogens and antigens of Haemophilus species. Isolated and purified analogue of Hin47 protein from Haemophilus influenzae exhibits decreased protease activity that is less 10% of activity of natural protein Hin47 but the same immunogenic properties as natural protein due to substitution or incorporation of at least one amino acid in native protein determining protease activity. Amino acid can be taken among amino acids 195-201, His-91 or Asp- 121 of native protein Hin47. Chimeric molecule comprises analogue of protein Hin47 of Haemophilus influenzae bound with polysaccharide. Recombinant plasmid DS-1011-1-1 (pT7/Hin47*) carries nucleic acid molecule expressing analogue of protein Hin47 with substitution of Ser-197 for alanine. At least a single amino acid residue of protein Hin47 determining protease activity is identified. For removal or substitution of nucleotide sequence encoding this amino acid site-directed mutagenesis of gene hin47 is carried out. Mutant gene is incorporated into cell to obtain transformed cell and the latter is cultured to yield analogue of Hin47. Immunogenic composition comprises effective amount of analogue Hin47. Interaction of sample with analogue Hin47 is carried out to obtain complexes comprising analogue Hin47 and recognizing its antibodies specifically if they present in sample. In subject immunization antibodies exhibiting specificity to protein Hin47 are obtained. Interaction of sample with antibodies is carried out. Diagnostic set for assay of antibodies presence that are able to recognize protein Hin47 specifically comprises in sample analogue of protein Hin47 and agents providing interaction of analogue with sample. Invention ensures to obtain vaccine preparations against sicknesses caused by pathogenic microorganism Haemophilus influenzae. EFFECT: improved method of preparing, valuable biological and medicinal properties. 18 cl, 25 dwg, 3 tbl, 14 ex
To evaluate outcomes of patients undergoing heart transplants (HTs) using an intra-aortic balloon pump (IABP) under exception status. Adult patients supported by an IABP who underwent HT between November 18, 2018, and December 31, 2020, as documented in the United Network for Organ Sharing, were included. Patients were stratified according to requests for exception status. Kaplan-Meier methodology was used to look for differences in survival between groups. A total of 1284 patients were included; 492 (38.3%) were transplanted with an IABP under exception status. Exception status patients had higher body mass index, were more likely to be Black, and had longer waitlist times. Exception status patients received organs from younger donors, had a shorter ischemic time, and had a higher frequency of sex mismatch. The 1-year posttransplant survival was 93% for the nonexception and 88% for the exception IABP patients (hazard ratio: 1.85 [95% confidence interval: 1.12-2.86, P = .006]). The most common reason for requesting an exception status was inability to meet blood pressure criteria for extension (37% of patients). The most common reason for an extension request for an exception status was right ventricular dysfunction (24%). IABP patients transplanted under exception status have an increased 1-year mortality rate posttransplant compared with those without exception status.
Group A streptococcus (GAS) is found in 20% to 40% of cases of childhood pharyngitis; the remaining cases are viral. Streptococcal pharyngitis ('strep throat') deserves antibiotics, while these are not indicated in viral cases. Because signs and symptoms of streptococcal and viral cases overlap, most guidelines recommend relying on a diagnostic test to identify Group A streptococcus to select who should receive antibiotics. In most settings, the first-line test to detect Group A Streptococcus is a rapid antigen detection test based on a throat swab, and the reference standard to identify streptococcal cases is throat culture. Recently, new rapid tests were developed. They use molecular techniques, such as rapid PCRs or LAMP, based on throat swabs. We hypothesize that these new molecular tests are sensitive enough to be performed on saliva swabs instead of throat swabs. Collecting saliva is less invasive and could be done by personnel with limited training.
The safety of immunization with live viral vaccines following rituximab product therapy has not been studied and vaccination with live virus vaccines is not recommended before or during treatment.

For patients treated with RIABNI, physicians should review the patient's vaccination status and patients should, if possible, be brought up-to-date with all immunizations in agreement with current immunization guidelines prior to initiating RIABNI and administer non-live vaccines at least 4 weeks prior to a course of RIABNI.

The effect of rituximab on immune responses was assessed in a randomized, controlled study in patients with RA treated with rituximab and methotrexate (MTX) compared to patients treated with MTX alone. A response to pneumococcal vaccination (a T-cell independent antigen) as measured by an increase in antibody titers to at least 6 of 12 serotypes was lower in patients treated with rituximab plus MTX as compared to patients treated with MTX alone (19% vs. 61%). A lower proportion of patients in the rituximab plus MTX group developed detectable levels of anti-keyhole limpet hemocyanin antibodies (a novel protein antigen) after vaccination compared to patients on MTX alone (47% vs. 93%).

A positive response to tetanus toxoid vaccine (a T-cell dependent antigen with existing immunity) was similar in patients treated with rituximab plus MTX compared to patients on MTX alone (39% vs. 42%). The proportion of patients maintaining a positive Candida skin test (to evaluate delayed type hypersensitivity) was also similar (77% of patients on rituximab plus MTX vs. 70% of patients on MTX alone).

Most patients in the rituximab-treated group had B-cell counts below the lower limit of normal at the time of immunization. The clinical implications of these findings are not known.
Each Macrobid capsule contains two forms of nitrofurantoin. Twenty-five percent is macrocrystalline nitrofurantoin, which has slower dissolution and absorption than nitrofurantoin monohydrate. The remaining 75% is nitrofurantoin monohydrate contained in a powder blend which, upon exposure to gastric and intestinal fluids, forms a gel matrix that releases nitrofurantoin over time. Based on urinary pharmacokinetic data, the extent and rate of urinary excretion of nitrofurantoin from the 100 mg Macrobid capsule are similar to those of the 50 mg or 100 mg Macrodantin®(nitrofurantoin macrocrystals) capsule. Approximately 20-25% of a single dose of nitrofurantoin is recovered from the urine unchanged over 24 hours.

Plasma nitrofurantoin concentrations after a single oral dose of the 100 mg Macrobid capsule are low, with peak levels usually less than 1 mcg/mL. Nitrofurantoin is highly soluble in urine, to which it may impart a brown color. When Macrobid is administered with food, the bioavailability of nitrofurantoin is increased by approximately 40%.

Amiodarone hydrochloride causes symptomatic bradycardia or sinus arrest with suppression of escape foci in 2 to 4% of patients. The risk is increased by electrolytic disorders or use of concomitant antiarrhythmics or negative chronotropes [see Drug Interactions (7)]. Bradycardia may require a pacemaker for rate control. 

Postmarketing cases of symptomatic bradycardia, some requiring pacemaker insertion and at least one fatal, have been reported when ledipasvir/sofosbuvir or sofosbuvir with simeprevir were initiated in patients on amiodarone. Bradycardia generally occurred within hours to days, but in some cases presented up to 2 weeks after initiating antiviral treatment. Bradycardia generally resolved after discontinuation of antiviral treatment. The mechanism for this effect is unknown. Monitor heart rate in patients taking or recently discontinuing amiodarone when starting antiviral treatment [see Drug Interactions (7)].
This study explores the utility of a tablet computer-based, individually-tailored technology called Computer Intervention Authoring Software (CIAS) in the Emergency Department for discharge education on proper child car restraint safety. The investigators hypothesize that tablet-based, individually-tailored discharge instructions are more effective than current standard, one-size-fits-all, printed discharge instructions. This is a randomized, controlled, non-blinded trial of a convenience sample of 200 children age 0-21 years old who present to the Hasbro Children's Hospital Emergency Department by car and have access to a smartphone and/or email. Patients will be randomized to receive either (a) a brief tablet-based questionnaire followed by standard, paper discharge instructions or (b) a brief tablet-based questionnaire followed by the intervention - CIAS, a computer program that allows families to interact with a tablet computer to receive educational information customized to the patient. Children 13 years old and above will answer questions themselves instead of having their parent/guardian answer for them. Both group will be offered information for the Lifespan Injury Prevention Center's Kohl's Car Seat Program. Both groups will complete a questionnaire on the usefulness of their discharge education. One week after discharge, participants in both groups will receive an automatic text message and/or email message with a link to a web-based survey that will assess: knowledge of appropriate car restraints and whether the parent/patient engaged in any behavioral changes regarding child car restraint. These variables will be compared between the control and intervention groups.
Hemorrhage is a potentially life-threatening emergency that can occur at any time or place. Whether traumatic, congenital, surgical, disease-related, or drug-induced, bleeding can lead to severe complications or death. Therefore, the development of efficient hemostatic materials is critical. However, the results and prognosis demonstrated by clinical means of hemostasis do not reach expectations. With the development of technology, novel hemostatic materials have been developed from polysaccharides (chitosan, hyaluronic acid, alginate, cellulose, cyclodextrins, starch, dextran, and carrageenan), peptides (self-assembling peptides), and proteins (silk fibroin, collagen, gelatin, keratin, and thrombin). These new materials exhibit high hemostatic efficacy due to the enhancement or interaction of various hemostatic mechanisms. The main forms include adhesives, sealants, bandages, hemostatic powders, and hemostatic sponges. This article introduces the clotting process and principles of hemostatic methods and reviews the research on polysaccharide-, peptide-, and protein-based hemostatic materials in the last five years. The design ideas and hemostatic principles of polysaccharide-, peptide-, and protein-based hemostatic materials are mainly introduced. Finally, we summarize material designs, advantages, disadvantages, and challenges regarding hemostatic materials.
