Vaccinations are an important component of travel medicine. Beyond protection of travelers, vaccines are administered to prevent the importation of vaccine-preventable diseases at home and at destination. Proof of immunization to travel dates back to the first smallpox vaccine, developed by Edward Jenner in 1796. However, it took one century to generate the next vaccines against cholera, rabies, and typhoid fever. During the 20th century the armamentarium of vaccines used in travelers largely expanded with yellow fever, poliomyelitis, tetravalent meningococcal, and hepatitis A vaccines. The International Certificate of Inoculation and Vaccination was implemented in 1933. Currently there are vaccines administered to travelers following risk assessment, but also vaccines required according to the 2005 International Health Regulations and vaccines required at certain countries. Finally, within less than one year after the declaration of the coronavirus disease 2019 (COVID-19) pandemic, the first COVID-19 vaccines were launched and approved for emergency use to control the pandemic. Despite practical and ethical challenges, COVID-19 vaccine verifications have been widely used since spring 2021 in many activities, including international travel. In this article, we review the course of development of travel vaccines focusing on those for which a proof of vaccination has been or is required.Ocular surface disease (OSD) in the setting of thyroid eye disease (TED) is traditionally thought of as a natural consequence of anatomical changes such as proptosis and corneal exposure. check details However, a growing body of research suggests that ocular surface inflammation and multi-factorial changes to the homeostasis of the ocular surface contribute substantially to the OSD seen in TED patients. In this paper we review the existing literature which highlights the work and existing theories underlying this new paradigm shift.

This study aimed to investigate the effect of auriculotherapy on the intensity of physical and mood Premenstrual syndrome (PMS) symptoms.

Single-blind randomized, placebo-controlled clinical trial.

Federal University of Parana, Curitiba, Brazil.

Ninety-one women were randomly assigned to Auriculotherapy (AG), Placebo (PG), and Control (CG) groups. The intervention was 8 weeks long, done once per week. At each session in AG the microneedles were placed in seven points related to PMS symptoms (Anxiety; Endocrine; Muscle relaxation; Analgesia; Kidney; Shen Men; and Sympathetic). At PG the microneedles also were placed in seven points but unrelated to PMS symptoms (Tonsils; Vocal cords; Teeth; Eyes; Allergy; Mouth; and External nose).

Assessments of PMS symptoms (Premenstrual Syndrome Screening Tool), musculoskeletal pain (Nordic Musculoskeletal Questionnaire), anxiety (Beck Anxiety Inventory), and quality of life (WHOQOL-Bref) were done at baseline, before the 5th session, after program completion, and a month follow-up.

The AG and PG showed significantly lower scores of PMS symptoms, musculoskeletal pain, and anxiety. On the quality of life and follow-up analysis, the significance was observed only in PG.

Auriculotherapy can be used as adjunctive therapy to reduce the physical and mood PMS symptoms.

This descriptive study was conducted to determine knowledge and attitudes of university students on organ donation descriptive study.

The population of the study was composed of 1800 universty students. A data collection form measuring the students' socio-demographic characteristics and knowledge and attitudes on organ donation/transplantation was used. The data were collected by the researchers using a face-to-face interview technique. In the evaluation of data, descriptive statistics and chi-square analysis and Logistic Regression Analysis were used.

It was determined only 38.6% of the students wanted to donate their organs, and 10.7% did not want to donate their organs due to their religious beliefs. The students who had relatives waiting for organ donation, knew someone who had organ transplantation and heard about organ donation in the family wanted to donate their organs at a statistically significant level. It was determined that the students who were religious, studying in the faculty of theology, and thinking that organ donation is a sin, did not want to donate organs at a statistically significant level. It was determined that among these independent factors, organ donation rate increased by 0.410 with talking about organ donation in the family and by 0.613 with knowing someone waiting for organ transplant while thinking that organ donation is a sin decreased organ donation by 1.5 times.

The students avoided organ donation because of their religious beliefs and lack of knowledge on this subject.

The aim of the study was to assess the allosensitization of Polish patients qualified for a lung transplantation in our center. A retrospective study of 161 potential lung allograft recipients, also of 31 patients transplanted in the University Hospital of Gdansk, between June 2018 and December 2020 were performed. 121 potential recipients were thoroughly tested for immunization status before eventual lung transplantation. SAB-testing, PRA-CDC and vPRA assessment, and HLA typing were performed to guide donor-recipient matching and risk stratification. Then 73 patients were separated and qualified for the list of patients awaiting lung transplantation. Then 31 patients were transplanted based on a negative biological crossmatch result. The patients were generally not sensitized, as the median PRA-CDC was 0% (min 0; max 53), and the vPRA, calculated according to HLA ABDR (>2000 cut-off MFI), was 8% (min 0; max 99). If the cut-off was split into 2000 MFI for HLA ABDR, 10,000 MFI for HLAC, and 7000 MFI for HLA-DQ, the vPRA increased to 20% (min 0; max 99). The immunization status was assessed with single antigen-SAB assays. For class I, the number of any detectable alloantibodies was 14 (11.6%) 21 (17.35%) 16 (13.22%) for locus HLA-A/B/C, and 28 (23.14%) 30 (24.8%) 24 (19.8%) for locus HLA-DR/DQ/DP, respectively. The immunization of the transplanted patients was then analyzed in detail. Summarizing, the study is an analysis of the degree of anti-HLA immunization in the population of patients eligible for lung transplantation, which showed that this degree is of low intensity and can be effectively and safely and very precisely diagnosed before transplantation.Many extracellular matrix (ECM) associated proteins that influence ECM properties have Thrombospondin type 1 repeats (TSRs) which are modified with O-linked fucose. The O-fucose is added in the endoplasmic reticulum to folded TSRs by the enzyme Protein O-fucosyltransferase-2 (POFUT2) and is proposed to promote efficient trafficking of substrates. The importance of this modification for function of TSR-proteins is underscored by the early embryonic lethality of mouse embryos lacking Pofut2. To overcome early lethality and investigate the impact of the Pofut2 knockout on the secretion of POFUT2 substrates and on extracellular matrix properties in vivo, we deleted Pofut2 in the developing limb mesenchyme using Prrx1-Cre recombinase. Loss of Pofut2 in the limb mesenchyme caused significant shortening of the limbs, long bones and tendons and stiff joint resembling the musculoskeletal dysplasias in human and in mice with mutations in ADAMTS or ADAMTSL proteins. Limb shortening was evident at embryonic day 14.5 where loss of O-fucosylation led to an accumulation of fibrillin 2 (FBN2), decreased BMP and IHH signaling, and increased TGF-β signaling. Consistent with these changes we saw a decrease in the size of the hypertrophic zone with lower levels of Collagen-X. Unexpectedly, we observed minimal effects of the Pofut2 knockout on secretion of two POFUT2 substrates, CCN2 or ADAMTS17, in the developing bone. In contrast, CCN2 and two other POFUT2 substrates important for bone development, ADAMTS6 and 10, showed a decrease in secretion from POFUT2-null HEK293T cells in vitro. These combined results suggest that the impact of the Pofut2 mutation is cell-type specific. In addition, these observations raise the possibility that the O-fucose modification on TSRs extends beyond promoting efficient trafficking of POFUT2 substrates and has the potential to influence their function in the extracellular environment.Dysregulation of cathepsin S (Cat S), a cysteine protease involved in extracellular-matrix and basement membrane (BM) degradation, is a concomitant feature of several inflammatory skin diseases. Therefore, Cat S has been suggested as a potential therapeutic target. Flavonoids, which were identified as regulatory molecules of various proteolytic enzymes, exert beneficial effects on skin epidermis. Herein, thirteen flavonoid compounds were screened in vitro and in silico and neohesperidin dihydrochalcone (NHDC) was identified as a potent, competitive, and selective inhibitor (Ki=8±1 µM) of Cat S. Furthermore, Cat S-dependent hydrolysis of nidogen-1, a keystone protein of BM architecture, as well elastin, collagens I and IV was impaired by NHDC, while both expression and activity of Cat S were significantly reduced in NHDC-treated human keratinocytes. Moreover, a reconstructed human skin model showed a significant decrease of both mRNA and protein levels of Cat S after NHDC treatment. Conversely, the expression of nidogen-1 was significantly increased. NHDC raised IL-10 expression, an anti-inflammatory cytokine, and mediated STAT3 signaling pathway, which in turn dampened Cat S expression. Our findings support that NHDC may represent a valuable scaffold for structural improvement and development of Cat S inhibitors to preserve the matrix integrity and favor skin homeostasis during inflammatory events.Environmental exposure to toxicants is a major health issue and a leading risk factor for premature mortality worldwide, including environmental exposures to volatile organic compounds (VOCs), specifically Benzene, Toluene, Ethylbenzene, and Xylene (BTEX). While exposure to these compounds individually has shown behavioral and neurochemical effects, this investigation examined the impact of exposure to combined BTEX using a preclinical model. Male Swiss Webster mice were exposed to BTEX vapors designed to approximate environmental levels in urban communities. Animals were exposed to one of four treatment conditions a 0-ppm (air control), two BTEX groups representing levels of environmental-like exposure, and a fourth group modeling occupational-like exposure. These exposures were conducted in 1.5-h sessions, 2 sessions/day, 5 days/week, for 3 weeks. Effects on coordination (i.e., rotarod and inverted screen test), learning and memory (i.e., Y-maze), and locomotor behavior (i.e., movement during exposure) were assessed during and after exposure.
