The authors previously published positive peer-reviewed (21 raters using the Terzis scale) and photogrammetric (Emotrics) outcomes in patients who had undergone two-stage lower lip reanimations up to 2018. Other series have published surgeon and peer-rated results, but we know of only two (n=12) that have assessed patients' views using patient satisfaction surveys. This paper presents patient-rated outcomes (PROMS) in an 11-year series of both single and two-stage anterior belly of digastric muscle (ABDM) lower lip reanimations. Demographics, paralysis characteristics, operative details, and complications were recorded. Patients were telephoned and requested to complete the Glasgow Benefit Inventory (GBI) to assess patient-rated outcomes. Thirty-two patients were eligible (mean age 36.4 years). Twenty-one (63.6%) completed the GBI (mean score +33.3). More patients reported benefit than detriment (95.2% vs 4.8%). Complications were infrequent and included three cases of superficial infections and one of dermatitis. Four patients (12.5%) underwent minor revisions, mostly lipofilling of lip notches. The median (range) duration of follow up was 2.8 (0.3 - 8.5) years. ABDM transfer for lower lip reanimation is a safe, low morbidity procedure that enhances the psychological wellbeing of patients with facial palsy.We recently discovered a new family of prodrugs deriving from phenyl 4-(2-oxo-3-imidazolidin-1-yl)benzenesulfonates (PIB-SOs) bioactivatable by cytochrome P450 1A1 (CYP1A1) into potent antimitotics referred to as phenyl 4-(2-oxo-3-alkylimidazolidin-1-yl)benzenesulfonates (PAIB-SOs). PAIB-SOs display significant selectivity toward human breast cancer cells based on the N-dealkylation of PAIB-SOs into their corresponding PIB-SOs by CYP1A1. In this study, we have evaluated the molecular mechanism of the bioactivation of PAIB-SOs into PIB-SOs by branching the linear alkyl chain on the imidazolidin-2-one (IMZ) moiety of PAIB-SOs by branched alkyl groups such as isopropyl, isobutyl and sec-butyl. Our results show that PAIB-SOs bearing an isobutyl group on the IMZ moiety and either a methoxy, a chloro or a bromo group at positions 3, 3,5 or 3,4,5 on the aromatic ring B exhibit antiproliferative activity ranging from 0.13 to 6.9 μM and selectivity toward MCF7 and MDA-MB-468 mammary cancer cells comparatively to other cell lines tested. Moreover, the most potent and selective PAIB-SOs bearing an isobutyl group and either a 3,5-Cl (44), 3,5-Br (45) or a 3,4,5-OMe (46) on the IMZ moiety exhibit antiproliferative activity in the sub-micromolar range and high selectivity ratios toward mammary cancer cells. They stop the cell cycle of MCF7 cells in the G2/M phase and disrupt their cytoskeleton. Furthermore, our studies evidenced that PAIB-SOs bearing either an isopropyl, a sec-butyl or an isobutyl group are hydroxylated on the carbon atom adjacent to the IMZ (Cα-OH) but only PAIB-SOs bearing an isobutyl group are bioactivated into PIB-SOs. Finally, PAIB-SOs 45 and 46 exhibit low toxicity toward normal cells and chick embryos and are thus promising antimitotic prodrugs highly selective toward CYP1A1-expressing breast cancer cells.Development of small molecule PD-1/PD-L1 inhibitors as a novel immunotherapy strategy exhibits great promise. Herein, a novel series of quinazoline derivatives were designed, synthesized and their inhibitory activity against the PD-1/PD-L1 interaction was evaluated through a homogenous time-resolved fluorescence (HTRF) assay. Among them, the compound 39 exhibited the most potent inhibitory activity with an IC50 value of 1.57 nM. Furthermore, the cellular level assays revealed that 39 could inhibit the PD-1/PD-L1 interaction and restore T-cell function, and showed low toxicity on the PBMCs. In addition, the structure-activity relationships (SARs) of the novel quinazoline derivatives were explored and the binding mode of 39 with dimeric PD-L1 was analyzed by molecular docking. This work demonstrates that incorporation of pyrimidine group between the 2 and 3-positions of the biphenyl structure is an effective strategy for designing novel and more potent small molecule PD-1/PD-L1 inhibitors, and 39 can be regarded as a promising lead compound for further investigation.Bruton's tyrosine kinase (BTK) regulates multiple important signaling pathways and plays a key role in the proliferation, survival, and differentiation of B-lineage cells and myeloid cells. BTK is a promising target for the treatment of hematologic malignancies. Ibrutinib, the first-generation BTK inhibitor, was approved to treat several B-cell malignancies. Despite the remarkable potency and efficacy of ibrutinib against various lymphomas and leukemias in the clinics, there are also some clinical limitations, such as off-target toxicities and primary/acquired drug resistance. As strategies to overcome these challenges, second- and third-generation BTK inhibitors, BTK-PROTACs, as well as combination therapies have been explored. In this review, we summarize clinical developments of the first-, second- and third-generation BTK inhibitors, as well as recent advances in BTK-PROTACs and ibrutinib-based combination therapies.

Advanced cancer poses a threat to all aspects of being, potentially causing existential suffering. We explore what kind of existential concerns patients with advanced cancer disclose during a routine hospital consultation, and how they communicate such concerns.

We analyzed thirteen video-recorded hospital consultations involving adult patients with advanced cancer. The study has a qualitative and exploratory design, using procedures from microanalysis of face-to-face-dialogue.

Nearly all patients disclosed how the illness experience included losses and threats of loss that are strongly associated with existential suffering, displaying uncertainty about future and insecurity about self and coping. Patients usually disclosed existential concerns uninvited, but they did so indirectly and subtly, typically hiding concerns in biomedical terms or conveying them with hesitation and very little emotion.

Patients may have existential concerns they want to address, but they may be uncertain whether these are issues they can discuss with the physician.

Health professionals should be attentive to underlying existential messages embedded in the patient's questions and concerns. Acknowledging these existential concerns provides an opportunity to briefly explore the patient's needs and may direct how the physician tailors information and support to promote coping, autonomy, and existential health.

The current study aims to explore elderly (aged 65 or above) Chinese adults' intentions to get vaccinated against COVID-19 and the facilitators and barriers to vaccination intentions. We conducted in-depth interviews with 35 elderly adults in China through the lens of the integrative model of behavioral prediction. Selleck Orforglipron The results identified a number of facilitators, including convenience (both individual and collective), psychological and physiological wellbeing, collective wellbeing, supportive normative referents, and trust in the government, and some barriers, including vaccine ineffectiveness, side effects, safety, unsupportive normative referents, and the accessibility, affordability, and availability of COVID-19 vaccines. In addition, the results revealed participants' decision-making process collective wellbeing and trust in the government overrode perceived barriers and perceived individual-level risks, which eventually overwhelmingly led to a high level of intentions to get vaccinated. Practical implications related to vaccine promotion and trust in the government were discussed.

A 20-valent pneumococcal conjugate vaccine, PCV20, was developed to expand protection against vaccine-preventable pneumococcal disease. PCV20 contains the components of the 13-valent pneumococcal conjugate vaccine, PCV13, and includes capsular polysaccharide conjugates for 7 additional serotypes. Thus, PCV20 may cover those additional serotypes in individuals previously vaccinated with PCV13 or provide benefits of immunization with a conjugate vaccine to individuals previously immunized with a pneumococcal polysaccharide vaccine. This study described the safety and immunogenicity of PCV20 in adults ≥65years of age with prior pneumococcal vaccination.

This phase 3, multicenter, randomized, open-label study was conducted in the United States and Sweden. Adults ≥65years of age were enrolled into 1 of 3 cohorts based on their prior pneumococcal vaccination history (23-valent pneumococcal polysaccharide vaccine [PPSV23], PCV13, or both PCV13 and PPSV23). Participants were randomized 21 within their cohort to re regimens. Clinicaltrials.gov NCT03835975.

PCV20 was well tolerated and immunogenic in adults ≥65 years of age previously vaccinated with different pneumococcal vaccine regimens. Clinicaltrials.gov NCT03835975.

Healthcare workers (HCWs) were among the first groups to be vaccinated in Turkey. The data to be obtained by the vaccination of HCWs would guide wide spread vaccination programs.

The study included 330 HCWs working at Istanbul University-Cerrahpaşa, Cerrahpaşa Medical Faculty Hospital and vaccinated with inactive CoronaVac (Sinovac Life Sciences, China) SARS-CoV-2 vaccine in two doses (28days apart). Anti-Spike /RBD IgG levels were measured 14days after the first dose and 28days after the second dose. Chemiluminescent microparticle immunoassay (CMIA) (ARCHITECT IgG II Quant test, Abbott, USA), which is 100% compatible with plaque reduction neutralization test (PRNT), was used.

Of the participants, 211 (63.9%) were female, 119 (36.1%) were male, and mean age was 39.6±7.7years. In those without prior COVID-19 history; (n=255) antibody positivity was detected as 48.2% (95% CI 42.1-54.3) 14days after the first dose of vaccine, and 99.2% (95% CI 98.1-100) at day 28 after the second dose. Antibody titers weren those with prior history of COVID-19 than infection-naive group. Given no significant benefit of the second dose, a single shot of vaccination may be sufficient for those with prior history of COVID-19. Monitoring humoral and cellular immune responses, considering new variants, is required to validate this approach.

Meningococcal serogroup C (MenC) vaccination was introduced for 14-month-olds in the Netherlands in 2002, alongside a mass campaign for 1-18year-olds. Due to an outbreak of serogroup W disease, MenC vaccination was replaced for MenACWY vaccination in 2018, next to introduction of a booster at 14years of age and a catch-up campaign for 14-18year-olds. We assessed meningococcal ACWY antibodies across the Dutch population in 2016/17 and 2020.

In a nationwide cross-sectional serosurvey in 2016/17, sera from participants aged 0-89years (n=6886) were tested for MenACWY-polysaccharide-specific (PS) serum IgG concentrations, and functional MenACWY antibody titers were determined in subsets. Moreover, longitudinal samples collected in 2020 (n=1782) were measured for MenACWY-PS serum IgG concentrations.

MenC antibody levels were low, except in recently vaccinated 14-23month-olds and individuals who were vaccinated as teenagers in 2002, with seroprevalence of 59% and 20-46%, respectively. Meningococcal AWY antibody levels were overall low both in 2016/17 and in 2020.
