Attention deficit hyperactivity disorder (ADHD) is a disorder in which problems with paying attention and focusing disrupt people's lives. Betahistine is a drug that activates histamine, a compound found in the human body that regulates immune response and acts as a neurotransmitter. Increased availability of histamine in the brain is known to enhance attention and cognition. In previous studies, betahistine increased vigilance in healthy participants. Presently, betahistine is used outside the United States to treat vertigo, but at doses that are too low to have an effect on attention and cognition. Based on data regarding the use of betahistine outside the United States and on data from other studies using betahistine, there do not appear to be any significant side effects from its use at low doses. This study will determine both whether betahistine is effective in increasing vigilance in people with ADHD and whether it has any side effects at higher doses.

Participation in this study will last approximately 4 weeks. Participants will first attend a screening visit that will include a review of their medical and psychiatric history, a physical examination, vital signs measurements, an electrocardiogram (EKG) test, blood and urine sample collection, an eating questionnaire, and a clinical interview to confirm an ADHD diagnosis. Eligible participants will then be randomly assigned to receive either betahistine or placebo on subsequent study visits.

Participants will then attend three weekly study visits, starting 1 week after completing screening. At each visit, participants will receive a dose of either betahistine or placebo. The dose of betahistine will increase at each visit, starting at 50 mg, then increasing to 100 mg, and then to 200 mg. Participants will be asked to refrain from eating and to drink only water in the 12 hours prior to study visits. Also at each visit, participants will have their vital signs measured, complete questionnaires concerning appetite and mood, perform attention and memory tests, provide several blood samples, undergo an EKG test, and perform a breathing test. Some of these tests will be repeated several times over the course of each study visit. Additionally, at the last study visit, participants will undergo a physical examination and provide urine samples.
Patients receive an electronic pill monitoring system comprising an empty MEMS\^? medication bottle with TrackCap? CR. The mercaptopurine prescription is filled using this system. Beginning on day 1 of the third or later course of maintenance therapy, patients take all doses of mercaptopurine from the MEMS\^? medication bottle with TrackCap? CR for at least 169 days. The MEMS\^? TrackCap? CR is mailed to the Coordinating Center at the end of study. Patients also receive methotrexate PO as indicated by their individual chemotherapy regimen.
This is a before-after study. All subjects are administered dexamethasone 2mg BID for 5 days.
A 27-year-old woman was diagnosed with idiopathic thrombocytopenic purpura in the neonatal period, and was admitted to our hospital after presenting with impaired consciousness, purpura, nausea and vomiting, with a platelet count of 10×109/l. Congenital thrombotic thrombocytopenic purpura (cTTP) was suspected on the basis of recurrent thrombocytopenia and impaired consciousness, so tests for ADAMTS13 activity and inhibitor were performed. ADAMTS13 activity was severely decreased, ADAMTS13 inhibitor was negative, and platelet count increased after transfusion of fresh frozen plasma. These findings and the results of genetic testing done on all family members led to a diagnosis of cTTP. cTTP requires differential diagnosis even in adults. If a patient diagnosed with ITP in childhood has a history or findings that suggest cTTP during follow-up observation, it is necessary to actively consider ADAMTS13 testing.
An aqueous camphor solution is prepared by agitating pulverised camphor and water, allowing the mixture to stand, adding sodium chloride, magnesium chloride and calcium chloride in a respective ratio by weight one to another of about 18:6:1, and filtering off the undissolved camphor.  The camphor is used in a large excess of the quantity soluble-e.g. 40 gms./litre, and the salts may be present in the concentrations: Na Cl, 20 gms./l.; MgCl2. 6H2O, 15 gms./l.; and Ca Cl2 (anhydrous), 1.1 gm./l., while the final solution contains a saturating proportion of camphor, i.e. 1.15 gms./l.  The solution may be applied topically or administered orally, and is said to have antipruritic and antiseptic properties.

BACKGROUND: Chronic Gulf War Illness (GWI) is characterized by cognitive and mood impairments, as well as persistent neuroinflammation and oxidative stress. This study aimed to investigate the efficacy of Epidiolex®, a Food and Drug Administration (FDA)-approved cannabidiol (CBD), in improving brain function in a rat model of chronic GWI.
METHODS: Six months after exposure to low doses of GWI-related chemicals [pyridostigmine bromide, N,N-diethyl-meta-toluamide (DEET), and permethrin (PER)] along with moderate stress, rats with chronic GWI were administered either vehicle (VEH) or CBD (20 mg/kg, oral) for 16 weeks. Neurobehavioral tests were conducted on 11 weeks after treatment initiation to evaluate the performance of rats in tasks related to associative recognition memory, object location memory, pattern separation, and sucrose preference. The effect of CBD on hyperalgesia was also examined. The brain tissues were processed for immunohistochemical and molecular studies following behavioral tests.
RESULTS: GWI rats treated with VEH exhibited impairments in all cognitive tasks and anhedonia, whereas CBD-treated GWI rats showed improvements in all cognitive tasks and no anhedonia. Additionally, CBD treatment alleviated hyperalgesia in GWI rats. Analysis of hippocampal tissues from VEH-treated rats revealed astrocyte hypertrophy and increased percentages of activated microglia presenting NOD-, LRR- and pyrin domain-containing protein 3 (NLRP3) complexes as well as elevated levels of proteins involved in NLRP3 inflammasome activation and Janus kinase/signal transducers and activators of the transcription (JAK/STAT) signaling. Furthermore, there were increased concentrations of proinflammatory and oxidative stress markers along with decreased neurogenesis. In contrast, the hippocampus from CBD-treated GWI rats displayed reduced levels of proteins mediating the activation of NLRP3 inflammasomes and JAK/STAT signaling, normalized concentrations of proinflammatory cytokines and oxidative stress markers, and improved neurogenesis. Notably, CBD treatment did not alter the concentration of endogenous cannabinoid anandamide in the hippocampus.
CONCLUSIONS: The use of an FDA-approved CBD (Epidiolex®) has been shown to effectively alleviate cognitive and mood impairments as well as hyperalgesia associated with chronic GWI. Importantly, the improvements observed in rats with chronic GWI in this study were attributed to the ability of CBD to significantly suppress signaling pathways that perpetuate chronic neuroinflammation.
OBJECTIVE: The objective of this study was to evaluate the feasibility and acceptability of postpartum hepatitis C virus (HCV) treatment integrated within a substance use treatment program for pregnant and postpartum people with opioid use disorder (OUD).
METHODS: We conducted a prospective pilot clinical trial of sofosbuvir/velpatasvir (SOF/VEL) treatment among postpartum people with OUD and HCV. Feasibility outcomes included rates of HCV treatment utilization and completion, medication adherence, and sustained virologic response 12 weeks after treatment completion (SVR12). Acceptability was measured through self-reported adverse effects and medication adherence.
RESULTS: From January 2018 to August 2021, 164 pregnant people received care for OUD at the study site. Among those, 64 (39.0%) were HCV antibody positive and 45 (27.4%) had active HCV infection. Among 45 eligible patients, 32 (71.1%) enrolled and 21 (46.7%) initiated HCV treatment. Of 21 participants who initiated treatment, 16 (76.2%) completed the SOF/VEL treatment, and 11 (52.4%) completed the SVR12. All participants who completed treatment were cured. Common reasons for dropout during the HCV clinical care cascade were OUD treatment discontinuation, illicit substance use recurrence, and lost to follow-up. Participants reported high satisfaction with HCV treatment, including minimal adverse effects, and no HCV treatment concerns.
CONCLUSIONS: Nearly half of pregnant people with HCV initiated postpartum treatment within an integrated care model of HCV treatment within a substance use treatment program. Postpartum SOF/VEL was efficacious, tolerable, and acceptable. Despite this, postpartum HCV treatment among people with OUD remains challenging, and many barriers remain.
Global longitudinal strain has been established as a reliable tool to assess global left ventricular function and a marker of subclinical left ventricular dysfunction unrecognized by the ejection fraction. On the other hand, ventricular arrhythmias are the most common cause of sudden cardiac death. Their early detection is a challenge. Possible prognostic markers for the risk of ventricular arrhythmias are discussed in the literature - electrocardiographic, cardiac magnetic resonance, computed tomography, radionuclide imaging, and markers from new echocardiographic techniques. Of the latter, at this stage of knowledge, several markers have been discussed as informative for predicting ventricular arrhythmias - global longitudinal strain, radial strain and mechanical dispersion, and most recently, myocardial work. As far as we are informed, global longitudinal strain is particularly useful in patients with normal echocardiographic parameters such as left ventricular ejection fraction, left atrial diameter, left ventricular wall thickness, and aortic root. The relationship between mechanical dispersion and ventricular arrhythmias has been widely studied. The relationship has been studied more in some patient populations - heart failure, ischemic heart disease, long QT syndrome and arrhythmogenic cardiomyopathy, congenital heart disease. The role of mechanical dispersion as a predictor of ventricular arrhythmias in metabolic syndrome is scarce.
As in patients receiving other immunosuppressants, those patients receiving cyclosporine are at increased risk for development of lymphomas and other malignancies, particularly those of the skin. Patients taking cyclosporine should be warned to avoid excess ultraviolet light exposure. The increased risk appears related to the intensity and duration of immunosuppression rather than to the use of specific agents. Because of the danger of oversuppression of the immune system resulting in increased risk of infection or malignancy, a treatment regimen containing multiple immunosuppressants should be used with caution. Some malignancies may be fatal. Transplant patients receiving cyclosporine are at increased risk for serious infection with fatal outcome.
Patients in this arm are discharged from the ED with an additional information sheet about their prescribed opioid pain medication, via the intervention titled "Additional Opioid Information". The sheet is read aloud to them by a research assistant. They are called 4-7 days later for a follow up survey.
Approximately 384 patients with moderate to severe plaque psoriasis will be enrolled and randomly assigned to one of the 2 treatment groups in a 1:1 ratio (192 patients in the Bmab 1200 group and 192 patients in the Stelara group). Patients who are diagnosed as moderate to severe chronic plaque psoriasis for at least 6 months and are candidate for systemic therapy or phototherapy at the time of the screening visit will be enrolled. The study is planned to be conducted in Europe and North America across approximately 48 sites in 5 countries. The study will be conducted in an outpatient setting, and the participation for each patient will consist of a screening period (up to 4 weeks/28 days) and a double-blind, active-controlled treatment period (52 weeks) with a rerandomization step for switching therapy (Bmab 1200 with Stelara ) before Week 16 dosing. The treatment period before the switch is TP1(Treatment Period1) and post switch is TP2(Treatment Period 2) (from Week 16 dosing to prior to Week 28 dosing) and TP3 (Treatment Period3)(from Week 28 dosing to Week 52). The total duration of the study (excluding the screening period) will be 52 weeks.
Pregnancy Category C. There are no well-controlled trials in pregnant women treated with ZIANA Gel. ZIANA Gel should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. ZIANA Gel was tested for maternal and developmental toxicity in New Zealand White Rabbits with topical doses of 60, 180 and 600 mg/kg/day. ZIANA Gel at 600 mg/kg/day (approximately 12 times the recommended clinical dose assuming 100% absorption and based on body surface area comparison) was considered to be the no-observed-adverse-effect level (NOAEL) for maternal and developmental toxicity following dermal administration of ZIANA Gel for 2 weeks prior to artificial insemination and continuing until gestation day 18, inclusive. For purposes of comparisons of the animal exposure to human exposure, the recommended clinical dose is defined as 1 g of ZIANA Gel applied daily to a 60 kg person.

Clindamycin

Teratology (Segment II) studies using clindamycin were performed orally in rats (up to 600 mg/kg/day) and mice (up to 100 mg/kg/day) (583 and 49 times amount of clindamycin in the recommended clinical dose based on body surface area comparison, respectively) or with subcutaneous doses of clindamycin up to 180 mg/kg/day (175 and 88 times the amount of clindamycin in the recommended clinical dose based on body surface area comparison, respectively) revealed no evidence of teratogenicity.

Tretinoin

In oral Segment III studies in rats with tretinoin, decreased survival of neonates and growth retardation were observed at doses in excess of 2 mg/kg/day (~78 times the recommended clinical dose assuming 100% absorption and based on body surface area comparison).

With widespread use of any drug, a small number of birth defect reports associated temporally with the administration of the drug would be expected by chance alone. Thirty cases of temporally associated congenital malformations have been reported during two decades of clinical use of another formulation of topical tretinoin. Although no definite pattern of teratogenicity and no causal association have been established from these cases, five of the reports describe the rare birth defect category, holoprosencephaly (defects associated with incomplete midline development of the forebrain). The significance of these spontaneous reports in terms of risk to the fetus is not known.

Dermal tretinoin has been shown to be fetotoxic in rabbits when administered in doses 40 times the recommended human clinical dose based on body surface area comparison. Oral tretinoin has been shown to be fetotoxic in rats when administered in doses 78 times the recommended clinical dose based on body surface area comparison.
Examining tissues outside the bloodstream in HIV-infected patients, patients with Idiopathic CD4 lymphopenia (ICL) and, for comparison, HIV-uninfected healthy volunteers (hereafter referred to as healthy volunteers), can provide insights into the pathogenesis of HIV infection and ICL. This protocol will provide a mechanism for sampling tissue sites. A total of 430 HIV-infected patients, 100 ICL patients and 105 healthy volunteers will be enrolled in these studies. To assess changes in viral load and immunological parameters at sites outside the bloodstream during therapy of HIV-infected patients, sequential tonsillar, lymph node, or intestinal biopsies, or bronchoscopy with bronchoalveolar lavage (BAL) will be undertaken during the course of therapy. In a small number of patients, sequential or simultaneous lymph node biopsies will be performed. In addition, uninfected healthy volunteers will be enrolled to have a tonsillar or intestinal biopsy, or bronchoscopy with BAL; this will allow comparison of immunologic parameters in HIVinfected and uninfected tonsillar or intestinal tissues, or BAL fluid. Finally, ICL patients may have tissue sampling to assess lymphocyte distribution and possible function in tissues to better understand the pathogenesis of their lymphopenia. Sequential or simultaneous tissue sampling may occur and longitudinal samples may also be obtained to assess stability in tissue compartments or effect of possible immunomodulatory treatments.
BACKGROUND: Hyperuricemia is associated with increased systemic inflammation. The systemic immune-inflammation index (SII) and systemic inflammation response index (SIRI) are novel systemic inflammation markers and prognostic markers. However, no studies have evaluated the association between the SII/SIRI and mortality risk in individuals with hyperuricemia. This study aimed to investigate the predictive value of the SII and SIRI for all-cause and cardiovascular mortality in a large cohort of hyperuricemia patients.
METHODS: We conducted a prospective cohort study using data from the National Health and Nutrition Examination Survey (NHANES) 2001-2020. Hyperuricemia was defined as serum uric acid (SUA) levels of ≥7 mg/dL in men and ≥6 mg/dL in women. The SII and SIRI were calculated based on complete blood count parameters. Associations with all-cause and cardiovascular mortality were analyzed using Cox proportional hazards models. Nonlinearity and effect modification were assessed using restricted cubic splines (RCS) and interaction analysis.
RESULTS: Among the 6181 participants with hyperuricemia aged 20 years and older, over a total 181 months of follow-up, there were 936 all-cause deaths, of which 195 were cardiovascular mortality. In the fully adjusted models, the hazard ratios (HRs) were 1.73 (95% CI 1.42-2.13) for the SII and 2.18 (95% CI 1.82-2.62) for the SIRI with all-cause mortality. The adjusted HRs were 2.08 (95% CI 1.37-3.14) for the SII and 2.32 (95% CI 1.56-3.45) for the SIRI with cardiovascular mortality. Spline models identified nonlinear U-shaped (SII) and J-shaped (SIRI) relationships of inflammation markers with mortality.
CONCLUSIONS: Elevated SII and SIRI are independent predictors of mortality in hyperuricemia patients. These inflammatory biomarkers may improve risk stratification in this high-risk population. Further research should evaluate utility in guiding preventive interventions.
Varying frequency, once to four times daily - 15 patients were included in a crossover study: IOP was checked daily for 3 days and for 9 hours on fourth day. Pilocarpine was started on day 5 once daily OD and BID OS; on day 9 once daily OD and QID OS; on day 12 QID OD and once daily OS; on day 16 once daily OD and QID OS; and on day 19 QID OD and once daily OS. No medications were used on days 23-25. IOP was measured on days 4, 8, 11, 15, 18, 22 and 25.
Despite initial disease remissions with cytotoxic chemotherapies, patients with AML and MDS often relapse and die of their disease. Novel strategies for targeting dependent pathways are needed. AML and MDS depend on blood vessels for survival and proliferation. OXi4503 is a novel microtubule targeting agent that selectively destroys cancer-associated blood vessels, induces cancer cell apoptosis via an ortho-quinone moiety and results in significant regressions of solid tumors. OXi4503 is currently being tested in phase I clinical trials of advanced solid tumors. In preclinical studies with human AML, OXi4503 was cytotoxic to leukemia cells, decreased size of chloromas, regressed leukemic cell engraftment in bone marrow and brought about phenotypic and molecular remissions. Given these results, we hypothesize that OXi4503 has disease remitting effects in myeloid malignancies such as AML and MDS. Before evaluating efficacy, safety and maximum tolerated dose of OXi4503 will be defined in AML and MDS patients. In addition, assessments of pharmacokinetic (PK) and pharmacokinetic (PD) parameters will be made, and relationships between dose and biologic activity will be defined. Results from this trial will provide new clinical data and biologic insight regarding the effects of OXi4503 in AML and MDS, and will serve as the basis for future efficacy trials.
Participants randomized to RNT-ACT will receive a total of 2 sessions of 60 minutes each as well as audio files to listen to between the occasions administered via internet. Previous studies have indicated that it doesn't make much of a difference whether the temporal distance between session 1 and session 2 is between 1 week and up to 3 months. At occasion 1, the time for occasion 2 is set. The temporal distance in days will noted for each patient. The treatment is inserted into the therapist's regular diary with 60 minutes session time and appropriate break before and after the treatment (e.g. at least 5-10 minutes) for preparation and post-administration where journal writing is included.
PURPOSE: Obesity is an important risk factor for secondary hypogonadism in men. Several studies evaluated the impact of bariatric surgery on gonadal function in men, proving an improvement in testosterone levels, without yet a global consensus on the impact of different surgical approaches. Objectives of the study are: to estimate the prevalence of obesity-associated gonadal dysfunction among men with severe obesity; to evaluate the response to bariatric surgery in terms of resolution of this condition, distinguishing between restrictive and restrictive-malabsorptive surgery.
METHODS: We conducted a retrospective evaluation of 413 males with severe obesity (BMI 44.7 ± 8.3 kg/m2). A subgroup of them (61.7%) underwent bariatric surgery. Anthropometric assessment (weight, BMI, waist and hip circumference), metabolic (glyco-lipidic asset and urate) and hormonal (morning gonadotropin and total testosterone) assessments were carried out at baseline and 3-6 months post-surgery.
RESULTS: Using a TT threshold of 2.64 ng/ml, 256 out of 413 (62%) patients were categorized as having biochemical hypogonadism. At multivariate analysis, the only parameter significantly associated with biochemical hypogonadism, was BMI value (p = 0.001). At 3-6 months after surgery, during the acute weight loss phase, only 20.1% of patients still had biochemical hypogonadism. At multivariate analysis, which included age, presurgical BMI, pre-surgical TT, surgical approach and %EWL, presurgical TT levels (p = 0.0004), %EWL (p = 0.04), and mixed restrictive-malabsorptive surgery (p = 0.01), were independently associated with the recovery of gonadal function.
CONCLUSIONS: The results of this study underscore the potential reversibility of obesity-associated gonadal dysfunction through bariatric surgery, highlighting the importance of considering surgical approach.
