BACKGROUND: In the US, non-Hispanic (NH) Black birthing persons show a two-fold greater risk of fetal death relative to NH white birthing persons. Since males more than females show a greater risk of fetal death, such loss in utero may affect the sex composition of live births born preterm (PTB; <37 weeks gestational age). We examine US birth data from 1995 to 2019 to determine whether the ratio of male to female preterm (i.e., PTB sex ratios) among NH Black births falls below that of NH whites and Hispanics.
METHODS: We acquired data on all live births in the US from January 1995 to December 2019. We arrayed 63 million live births into 293 "conception cohort" months of which 2,475,928 NH Black, 5,746,953 NH white, and 2,511,450 Hispanic infants were PTB. We used linear regression methods to identify trend and seasonal patterns in PTB sex ratios. We also examined subgroup differences in PTB sex ratios (e.g., advanced maternal ages, twin gestations, and narrower gestational age ranges).
RESULTS: The mean PTB sex ratio for NH Black births over the entire test period (1.06, 95% Confidence Interval [CI]: 1.05, 1.07) is much lower than that for NH white births (1.18, 95% CI: 1.17, 1.19). NH Black PTB sex ratios are especially low for twins and for births to mothers 35 years or older. Only NH white PTB sex ratios show a trend over the test period.
CONCLUSIONS: Analysis of over 10 million PTBs reveals a persistently low male PTB frequency among NH Black conception cohorts relative to NH white cohorts. Low PTB sex ratios among NH Black births concentrate among subgroups that show an elevated risk of fetal death. PTB sex ratios may serve as an indicator of racial/ethnic and subgroup differences in fetal death, especially among male gestations.
Enrolled physicians are randomly assigned to receive brief training in either: 1) behavioral weight control intervention or 2) obesity education. Enrolled patients are asked to see their physician for 2 weight control consultations during the year to discuss their weight and physical activity. Regardless of the training the physician receives, the weight control advice is tailored to the individual patient. Patients include men and women between the ages of 21 - 70 years, with a Body-Mass Index of 27 or greater, and they have met medical and other study eligibility criteria in order to safely participate. As a participant in the trial, all patients are asked to attend an initial baseline assessment, and two follow-up assessments; 3 and 12 months after their first weight control consultation visit with their physician in order to evaluate any changes in their weight, waist circumference, physical activity, eating patterns, and mood. The findings of this important study will shed light upon the role physician advice may have in helping overweight and obese patients lose weight and become more physically active.
Splenic leukocytes, particularly macrophage-expressed lipoxygenases, facilitate the biosynthesis of resolution mediators essential for cardiac repair. Next, we asked whether deletion of 12/15 lipoxygenase (12/15LOX) in macrophages impedes the resolution of inflammation following myocardial infarction (MI). Using 12/15flox/flox and LysMcre scheme, we generated macrophage-specific 12/15LOX (Mɸ-12/15LOX-/-) mice. Young C57BL/6J wild-type and Mɸ-12/15LOX-/- male mice were subjected to permanent coronary ligation microsurgery. Mice were monitored at day 1 (d1) to d5 (as acute heart failure [AHF]) and to d56 (chronic HF) post-MI, maintaining no MI as d0 naïve control animals. Post ligation, Mɸ-12/15LOX-/- mice showed increased survival (88% vs 56%) and limited heart dysfunction compared with wild-type. In AHF, Mɸ-12/15LOX-/- mice have increased biosynthesis of epoxyeicosatrienoic acid by 30%, with the decrease in D-series resolvins, protectin, and maresin by 70% in the infarcted heart. Overall, myeloid cell profiling from the heart and spleen indicated that Mɸ-12/15LOX-/- mice showed higher immune cells with reparative Ly6Clow macrophages during AHF. In addition, the detailed immune profiling revealed reparative macrophage phenotype (Ly6Clow) in Mɸ-12/15LOX-/- mice in a splenocardiac manner post-MI. Mɸ-12/15LOX-/- mice showed an increase in myeloid population that coordinated increase of T regulatory cells (CD4+/Foxp3+) in the spleen and injured heart at chronic HF compared with wild-type. Thus, macrophage-specific deletion of 12/15LOX directs reparative macrophage phenotype to facilitate cardiac repair. The presented study outlines the complex role of 12/15LOX in macrophage plasticity and T regulatory cell signaling that indicates that resolution mediators are viable targets to facilitate cardiac repair in HF post-MI.
A method for preserving spermatozoa (sperm) by air drying. A semen sample is received and the sperm are separated from contaminants in the semen sample. The sperm may be separated from the semen sample by layering the semen sample onto a two-layer discontinuous percoll layer followed by centrifugation or by centrifuging the semen sample. The sperm concentrate is spread onto a sterile plate and allowed to air dry. The air-dried sperm may be stored at 0 °C to 8 °C. The air-dried sperm may be recovered by adding a warm physiological solution to the air-dried sperm. The recovered sperm may be used for in vitro fertilisation or for intracytoplasmic sperm injection (ICSI).
Active rTMS treatment will be delivered at 10 Hz, 100% resting motor threshold, 2000 pulses delivered in five seconds per train with 10-second intra-train pause, delivered once daily five days per week, Monday through Friday for 10 days (10 total treatments). This protocol is adapted from Shen and colleagues (2016), who did not report any adverse events. Liu and colleagues (2020) also used the same protocol and only reported mild side effects of dizziness, headache, and insomnia, which resolved by the 30-day follow-up. However, it is unclear whether these side effects resolved sooner than the 30-day follow-up.
PROBLEM TO BE SOLVED: To obtain the subject compound having excellent functional characteristics and safety by a simple operation in a high yield, by formulating a specific alcohol with a phenol and an alkyl halide in the presence of a phase transfer catalyst in a two-phase system. SOLUTION: An alcohol or a phenol of formula I [R1 to R6 are each H, OH, phenyl, a group of formula II (R7 is a 0-3C hydrocarbon chain; R8 is a 1-7C hydrocarbon), etc.] is reacted with an alkyl halide of the formula R9 -X (R9 is methyl or ethyl; X is a halogen) in the presence of a phase transfer catalyst (e.g. a sulfonium compound, a phosphonium compound, etc.), in a two phase system to give the objective compound of formula III [R10 to R15 are each H, a 1-4C alkyl, an alkenyl, a group of formula IV (R16 is a 0-3 hydrocarbon chain; R17 is a 1-8C hydrocarbon chain) or the like]. The phase transfer catalyst used in the reaction is separated and recovered and is preferably reused in the reaction.
Echinococcus granulosus larvae can cause cystic echinococcosis (CE, also known as hydatid disease) in humans. The latent phase of hydatid disease lasts for years as a result of the slow growth of the cysts, which only become symptomatic when they are large. Therefore, CE is seldomly seen in very young children. Here we present a 4-year-old boy with two giant asymptomatic abdominal cysts. Ultrasound was inconclusive in regard to the nature of the cysts and serology for echinococcosis was negative, rendering CE improbable also in view of the young age. Nevertheless, in the absence of other conclusive explanations, the patient was started on albendazole. A subsequent diagnostic percutaneous puncture with direct microscopy of cyst fluid revealed parasitological evidence of echinococcosis. This case report shows that CE can present with giant cysts also at very young age and should be considered as a possible diagnosis in all children with giant abdominal cysts.
A cycle of therapy was defined as 3 weeks. Taxane was paclitaxel 225 mg/m\^2 infused over 180 minutes on Day 1 and subsequently every 3 weeks or docetaxel 75 mg/m\^2 infused over 60 minutes on Day 1 and subsequently every 3 weeks. Carboplatin was infused over 30 minutes on Day 1 and subsequently every 3 weeks.
Forty-two patients with knee OA and 42 healthy subjects participated in our study. Demographic data, body mass index, habits, comorbidities, medications of participants and disease duration and radiographic grade of knee OA patients were recorded. VAS was used to assess the severity of pain and WOMAC was used to assess pain and functional status in patients with OA. Algometer (pressure pain threshold measurement) and Central Sensitization Inventory were used to evaluate central sensitization in all participants. Pressure pain threshold (PPT) was measured at 3 different points: knee joint, cruris and forearm. The presence of kinesiophobia was assessed with the Tampa Scale af Kinesiophobia (TSK). Pain Catastrophizing Scale (PCS) and Beck Depression Inventory (BDI) were used to assess chronic pain related symptoms.
ABSTRACT The present invention relates to novel tumor-associated antigens, which elicit independently from a presentation via MHC a CD8-positive T-cell response. GM-CSF-Receptor alpha chain (CSF2RA) and Tyrosinase-related protein 2 (TRP-2) were found to be targets of CD8-positive T-cell clones which could detect the proteins on the surface of EILA I negative melanoma cells. Thus, the invention provides proteins, protein fragments and polypeptides of the novel antigens for use in medicine, for example for the treatment, diagnosis and prevention of a tumor disease. Furthermore provided are nucleic acids expressing the antigens of the invention, binding agents specific for the antigens of the invention, such as T-cell receptor chains and isolated T cells which are reactive against the antigens of the invention or which express the T-cell receptors of the invention. The invention further pertains to pharmaceutical compositions, especially vaccine compositions, comprising the antigens, nucleic acids, binding agents or T cells in accordance with the invention, and methods for the generation of T cells, which are specifically reactive to the antigens of the invention in an MHC-independent manner.

OBJECTIVE: This study aimed to investigate the effect of METTL3 knockdown on osteogenic differentiation of human periodontal ligament stem cells (PDLSCs) in the weak inflammation microenvironments, as well as the underlying mechanisms.
MATERIALS AND METHODS: PDLSCs were stimulated by lipopolysaccharide from Escherichia coli (E. coli LPS), followed by quantification of METTL3. METTL3 expression was assessed using RT-qPCR and Western blot analysis in periodontitis. METTL3 knockdown PDLSCs were stimulated with or without E. coli LPS. The evaluation included proinflammatory cytokines, osteogenic markers, ALP activity, and mineralized nodules. Bioinformatics analysis and Western blot determined the association between METTL3 and the PI3K/Akt pathway.
RESULTS: METTL3 was overexpressed in periodontitis. METTL3 knockdown in PDLSCs reduced proinflammatory cytokines, osteogenic markers, ALP activity, and mineralized nodules in both environments. Bioinformatics analysis suggested a link between METTL3 and the PI3K/Akt pathway. METTL3 knockdown inhibited PI3K/Akt signaling pathway activation.
CONCLUSION: METTL3 knockdown might inhibit osteogenesis in PDLSCs through the inactivation of PI3K/Akt signaling pathway. Concomitant findings might shed novel light on the roles and potential mechanisms of METTL3 in the LPS-stimulated inflammatory microenvironments of PDLSCs.
In both conditions, the contents of the UP manual were worked following the 2nd edition of the UP manual (Barlow et al., 2018). In the 8-session UP condition, each of the original 8 treatment modules was worked on per week. The sessions were group sessions, 2 hours long and weekly.
BACKGROUND: Subarachnoid hemorrhage (SAH) can lead to acute or delayed cerebral ischemia. Recent findings have revealed that spasm of microvessels, called microvasospasm, may contribute to SAH-related cerebral ischemia, and perivascular inflammation is considered important in the development of microvasospasms. However, owing to the difficulty in investigating the dynamics of vascular and perivascular events, little is known about the mechanisms underlying microvasospasms.
METHODS: We established an experimental system aiming to investigate the vascular and perivascular pathology of SAH by combining a SAH mouse model with intravital 2-photon imaging. SAH was induced by intracisternal blood injection, and the distribution of erythrocytes, neutrophil behavior, and morphological changes in the pial arterioles were analyzed over time by 2-photon microscopy imaging. To further explore the role of neutrophils and neutrophil extracellular traps (NETs) in microvasospasm, we performed neutrophil depletion by intraperitoneal administration of neutrophil-specific antibody or NETs removal by intracisternal administration of DNase.
RESULTS: Erythrocytes were immediately distributed in the perivascular space of the arterioles after SAH induction; neutrophils intensively infiltrated the perivascular space within 2 days and subsequently showed NETosis; and pial arterioles in the same region developed pearl-string-like microvasospasms in the subacute phase. Neutrophil depletion significantly reduced the number of microvasospasms. Furthermore, the removal of perivascular NETs drastically reduced microvasospasms.
CONCLUSIONS: By establishing a unique experimental system, we demonstrated that perivascular NETs could be a new therapeutic target for microvasospasms.

Pelvic floor disorders (PFDs), such as pelvic organ prolapse (POP) and urinary incontinence (UI), severely affect women's quality of life. Among these, stress urinary incontinence (SUI) is the most common, impacting a significant proportion of women. In the US, the lifetime risk of undergoing surgery for UI or POP stands at 20%. Pregnancy-related factors, notably delivery method and UI occurrence during pregnancy, have a potent correlation with PFD onset. The pathophysiology of PFDs during pregnancy is complex, with factors like increased intra-abdominal pressure, changes in bladder neck mobility, and shifts in pelvic floor muscle strength and collagen metabolism playing pivotal roles. PFD risk factors span across pregnancy, labor, and the postnatal phase and include UI or fecal incontinence (FI) during pregnancy, advanced maternal age, elevated BMI, multiple births, instrumental and spontaneous vaginal deliveries, and newborns weighing over 4000 grams. Conversely, Cesarean deliveries are linked with a reduced long-term risk of UI and POP compared to vaginal births. Current prognostic models can predict the likelihood of PFD development based on variables such as delivery method, number of births, and familial history. Preventive measures encompass lifestyle changes like caffeine reduction and weight management, alongside pelvic floor muscle training (PFMT) during pregnancy. Thus, expectant mothers are advised to participate in physical activities, prominently including PFMT.

Microsatellite stable (MSS) colorectal cancers (CRCs) are often resistant to anti-programmed death-1 (PD-1) therapy. Here, we show that a CRC pathogen, Fusobacterium nucleatum (Fn), paradoxically sensitizes MSS CRC to anti-PD-1. Fecal microbiota transplantation (FMT) from patients with Fn-high MSS CRC to germ-free mice bearing MSS CRC confers sensitivity to anti-PD-1 compared to FMT from Fn-low counterparts. Single Fn administration also potentiates anti-PD-1 efficacy in murine allografts and CD34+-humanized mice bearing MSS CRC. Mechanistically, we demonstrate that intratumoral Fn generates abundant butyric acid, which inhibits histone deacetylase (HDAC) 3/8 in CD8+ T cells, inducing Tbx21 promoter H3K27 acetylation and expression. TBX21 transcriptionally represses PD-1, alleviating CD8+ T cell exhaustion and promoting effector function. Supporting this notion, knockout of a butyric acid-producing gene in Fn abolishes its anti-PD-1 boosting effect. In patients with MSS CRC, high intratumoral Fn predicts favorable response to anti-PD-1 therapy, indicating Fn as a potential biomarker of immunotherapy response in MSS CRC.

This study aimed to report our experience with the use of Sirolimus (SRL) in pediatric liver transplant patients with chronic rejection or steroid-resistant rejection with hepatic fibrosis, focusing on their histological evolution. All pediatric liver transplant recipients who received off-label treatment with SRL for chronic ductopenic rejection or cortico-resistant rejection between July 2003 and July 2022 were included in the study. All nine patients included in the study showed improvement in liver enzymes and cholestasis parameters as soon as 1-month after post-SRL introduction. A decrease in fibrosis stage was observed in 7/9 (77.7%) patients at 36 months. All but one patient experienced an improvement in the Rejection Activity Index and ductopenia at 12 months. A single patient had to discontinue SRL treatment owing to nephrotic proteinuria. In conclusion, SRL may be a safe and effective treatment for chronic and steroid-resistant rejection and may improve allograft rejection-related fibrosis and ductal damage.
The invention relates to a pharmaceutical pellet which comprises a spherical core containing an active ingredient with a smooth surface and a coating on the core which controls the release of the active ingredient in a pH-independent manner. With such a pellet the release of the active ingredient can follow a profile with a lag phase of 60 minutes to 840 minutes, a proportion of 5 wt. % or less of the active ingredient being released during the lag phase. The active ingredient can furthermore be released from the pellet with a profile such that after the lag phase the release of the active ingredient amounts to between 3 and 25 wt. % per hour.  The active ingredient can also be in the form of a metoprolol salt.
BACKGROUND: Most surveillance systems for catheter-related bloodstream infections (CRBSI) and central line-associated bloodstream infections (CLABSI) are based on manual chart review. Our objective was to validate a fully automated algorithm for CRBSI and CLABSI surveillance in intensive care units (ICU).
METHODS: We developed a fully automated algorithm to detect CRBSI, CLABSI and ICU-onset bloodstream infections (ICU-BSI) in patients admitted to the ICU of a tertiary care hospital in Switzerland. The parameters included in the algorithm were based on a recently performed systematic review. Structured data on demographics, administrative data, central vascular catheter and microbiological results (blood cultures and other clinical cultures) obtained from the hospital's data warehouse were processed by the algorithm. Validation for CRBSI was performed by comparing results with prospective manual BSI surveillance data over a 6-year period. CLABSI were retrospectively assessed over a 2-year period.
RESULTS: From January 2016 to December 2021, 854 positive blood cultures were identified in 346 ICU patients. The median age was 61.7 years [IQR 50-70]; 205 (24%) positive samples were collected from female patients. The algorithm detected 5 CRBSI, 109 CLABSI and 280 ICU-BSI. The overall CRBSI and CLABSI incidence rates determined by automated surveillance for the period 2016 to 2021 were 0.18/1000 catheter-days (95% CI 0.06-0.41) and 3.86/1000 catheter days (95% CI: 3.17-4.65). The sensitivity, specificity, positive predictive and negative predictive values of the algorithm for CRBSI, were 83% (95% CI 43.7-96.9), 100% (95% CI 99.5-100), 100% (95% CI 56.5-100), and 99.9% (95% CI 99.2-100), respectively. One CRBSI was misclassified as an ICU-BSI by the algorithm because the same bacterium was identified in the blood culture and in a lower respiratory tract specimen. Manual review of CLABSI from January 2020 to December 2021 (n = 51) did not identify any errors in the algorithm.
CONCLUSIONS: A fully automated algorithm for CRBSI and CLABSI detection in critically-ill patients using only structured data provided valid results. The next step will be to assess the feasibility and external validity of implementing it in several hospitals with different electronic health record systems.
PURPOSE:A solution containing a colony formation-stimulating factor originating from human is treated with an anion-exchanger in a cartridge from with a swirl structure of mainly cellulose-containing sheet material to effect high- efficient purification of the factor. CONSTITUTION:A solution containing colony formation-stimulating factor (abbreviated to CSF) originating from human urine is treated with a cartridge of anion exchanger which has a swirl structure of a minly cellulose-containing sheet. For example, a solution containing CSF is passed through the cartridge at 5-7pH and 20ms/cm (25 deg.C) conductivity to effect adsorption and almost of the contaminants are allowed to pass through. A dilute salt solution of 5-7pH is used to effect rinsing. Then CSF is eluted with a conc. salt solution of 5-9H, e.g., a phosphate buffer solution of 30 ms/cm (25 deg.C) conductivity. Further the combination of ultrafiltration before the anion-exchange treatment is preferred.
