Possible association between obesity and periodontitis in patients with Down syndrome
2017
Background The present study was carried out to evaluate the possible association between obesity and periodontitis in patients with DS, and to explore which measure of obesity is most closely correlated to periodontitis. Material and Methods A prospective observational study was made to determine whether obesity is related to periodontal disease in patients with DS. The anthropometric variables were body height and weight, which were used to calculate BMI and stratify the patients into three categories: < 25(normal weight), 25-29.9 (overweight) and ≥ 30.0 kg/m2 (obese). Waist circumference and hip circumference in turn was recorded as the greatest circumference at the level of the buttocks…
Prevalence and Potential Risk Factors of Helicobacter pylori Infection among Asymptomatic Individuals in Kazakhstan
2021
Background: Helicobacter pylori (H. pylori) infection is associated with several risk factors such as demographic, socioeconomic status and personal habits, which vary in different populations. This is the most up-to-date data on H. pylori prevalence and potential risk factors for H. pylori infection among asymptomatic middle-aged individuals in Kazakhstan. Methods: Apparently healthy individuals aged 40 to 64, who took part in the health control in the outpatient clinic, were invited to participate in the study; answered a questionnaire, donated a blood sample. The antibodies to H. pylori were analysed by latex agglutination method. The baseline characteristics of study subjects with or wi…
Number needed to freeze: cumulative live birth rate after fertility preservation in women with endometriosis
2021
Research question: How does the number of oocytes used affect the cumulative live birth rate in endometriosis patients who had their oocytes vitrified for fertility preservation (FP)? Design: Retrospective observational study including data from 485 women with endometriosis who underwent FP from January 2007 to July 2018. Survival curves and Kaplan-Meier plots were used to analyse the cumulative live birth rate (CLBR) according to the number of vitrified oocytes used. Data were stratified according to age, stage of the disease and ovarian surgery prior to FP (operated vs. non-operated). Endometriosis curves were compared to plots developed using elective fertility preservation (EFP) patient…
Aspergilosis invasora en el paciente con enfermedad oncohematológica
2018
Invasive aspergillosis is the most common invasive fungal infection in patients with acute hematological malignancies or treated with hematopoietic stem cell transplantation due to the marked alteration of the physiological mechanisms of antifungal immunity that takes place in these situations. For this reason, antifungal prophylaxis has a relevant role in these patients. The introduction of new antifungal agents has motivated the updating of recommendations for prophylaxis and treatment in different guidelines. The objectives of this chapter are a brief review of the mechanisms of immunity against fungi, the definition of risk for developing an invasive fungal infection and an update of th…
Identification of circumferential regional heterogeneity of ascending thoracic aneurysmal aorta by biaxial mechanical testing
2019
Abstract Ascending thoracic aortic aneurysm (ATAA) in patients with bicuspid aortic valve (BAV) can present an asymmetrical aortic dilatation compared with patients with tricuspid aortic valve (TAV). This pattern of aneurysm dilatation led us to hypothesize that biomechanical differences likely induced by regional heterogeneity of material properties can underlie the observed asymmetric enlargement discrepancies between BAV ATAA and TAV ATAA. This study aimed to characterize the mechanical properties and associated aortic tissue stiffness changes along the circumferential direction of aortic rings collected from surgically-repaired patients with ATAA. Biaxial material testing was performed …
Obinutuzumab-Based Immunochemotherapy Prolongs Progression-Free Survival and Time to Next Anti-Lymphoma Treatment in Patients with Previously Untreat…
2018
Abstract Introduction: Immunochemotherapy is standard of care treatment for previously untreated patients (pts) with advanced stage follicular lymphoma (FL). However, the majority of pts relapse, with around 20% relapsing within 2 years. Obinutuzumab (GA101; G) is a glycoengineered type II anti-CD20 monoclonal antibody (mAb) with increased antibody-dependent cell-mediated phagocytosis and cytotoxicity, and direct B-cell killing, compared with the type I mAb rituximab (R). The randomized Phase III GALLIUM study (NCT01332968) compared the efficacy and safety of G-chemotherapy (G-chemo) vs R-chemotherapy (R-chemo) in previously untreated pts with advanced stage FL. In the primary analysis (PA)…
Bone regeneration in the stem cell era: safe play for the patient?
2017
The past decade has seen outstanding scientific progress in the field of stem cell (SC) research and clinical application. SCs are convenient both technically and biologically: they are easy to find and to culture and they can differentiate in virtually all tissues and even in whole organs. Induced pluripotent stem cells (iPSs) are a type of pluripotent SC generated in vitro directly from mature cells through the introduction of key transcription factors. The use of iPSs, however tantalizing, poses serious safety concerns because of their genomic instability. Recently, it has been suggested that the main mechanism of SC action relies on paracrine signals. Therefore, the secretome would be p…
Efficacy and safety of human papillomavirus vaccination in HIV-infected patients: a systematic review and meta-analysis
2021
AbstractThe prophylactic vaccines available to protect against infections by HPV are well tolerated and highly immunogenic. People with HIV have a higher risk of developing HPV infection and HPV-associated cancers due to a lower immune response, and due to viral interactions. We performed a systematic review of RCTs to assess HPV vaccines efficacy and safety on HIV-infected people compared to placebo or no intervention in terms of seroconversion, infections, neoplasms, adverse events, CD4+ T-cell count and HIV viral load. The vaccine-group showed a seroconversion rate close to 100% for each vaccine and a significantly higher level of antibodies against HPV vaccine types, as compared to the …
Patients With Cancer and COVID-19: A WhatsApp Messenger-Based Survey of Patients' Queries, Needs, Fears, and Actions Taken
2020
PURPOSE This descriptive investigation was undertaken at three oncology units to report queries, needs, and fears related to severe acute respiratory syndrome coronavirus 2 (COVID-19) of patients with cancer and to avoid uncontrolled treatment delays or withdrawal, behavioral mistakes, and panic. PATIENTS AND METHODS All queries spontaneously delivered through the WhatsApp instant messaging system commonly used by patients to communicate with oncology units were collected and grouped by homology in five categories. Responses to the queries were given according to recommendations by the Italian Association of Medical Oncology through WhatsApp and by subsequent phone calls. Patients were also…
Tumour mutational burden as a biomarker for immunotherapy: Current data and emerging concepts
2020
International audience; Treatment with immune checkpoint inhibitors targeting programmed cell death protein 1 (PD-1) or its ligand (PD-L1) can generate durable responses in various cancer types, but only in a subset of patients. The use of predictive biomarkers for response to PD-1/PD-L1 inhibitors is critical for patient selection. Expression of PD-L1 has demonstrated utility in patient selection. Tumour mutational burden (TMB) is an emerging biomarker for response to PD-1/PD-L1 inhibitors. The evaluation of this biomarker is based on the hypothesis that a high number of mutations in somatic exonic regions will lead to an increase in neoantigen production, which could then be recognised by…
