It has been a poorly diagnosed and its incidence has apparently increased in recent times, perhaps due to its greater recognition. Genetic /familial-based cases occur in childhood from an inherited disorder of a poor cytotoxic function of T / NK cells. In adults, the majority of patients have predisposing causes, such as Epstein Barr virus infection, neoplasms most commonly due to non-Hodgkin lymphoma of T origin, autoimmune processes, and rarely are some patients classified as idiopathic. Therapy is based on the administration of the LHH-94 treatment protocol, promoted by the Histiocytic Society. All cases with a genetic base require the subsequent application of an allogeneic transplantation of hematopoietic progenitors, which is also a therapeutic option for adults with disease resistant, progressive or recurrent.","PeriodicalId":75487,"journal":{"name":"Anales de la Real Academia Nacional de Medicina","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46981732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A descriptive cross-sectional study was carried out in three Spanish universities between February 1 and May 31, 2019, through a self-administered survey of 55 questions: baseline sociodemographic questionnaire, knowledge about vaccination, necessary vaccines in health personnel, sources of information and opinion on the teaching received in vaccinology. The scale had a Cronbach’s alpha level of 0.767. There was a 67.2% (1821/2709) contact rate, a 52.2% (951/1821) response rate, and an eligibility of 93.2% (887/951). The mean age was 21.7 ± 3.6 years, of which 67.9% (646/1821) were women. The mean score for knowledge was 44.6 (SD 4.3), with a good proportion of correct answers and with significant differences between first and second cycle students, in addition to differences by gender in two statements: vaccines are effective and vaccination must be mandatory to achieve universal coverage. 34.98% (332/949) did not know the vaccination schedule. The mean attitude score was 36.7 (SD 4.1). The main sources of information on vaccines came from the academic environment and the family / internet and 87.7% (828/951) declared only ≤3 courses related to vaccination. 80.1% (461/951) believed that doctors should be the best trained professionals in vaccination. 51.2% believed that universities should be the central institution for training in vaccines during postgraduate studies, compared to 25.2% professional associations, 16.4% scientific societies and only 5.4% the pharmaceutical industry.

The main objective of the present study is to analyze whether patients affected during the shortage by reduced dose courses, are at a higher risk of tumor recurrence than those receiving full dose schemes. Methods: Retrospective cohort study with a total sample of 154 subjects (60 treated during 2019 and 94 during 2017) with high-risk non-muscle invasive bladder cancer and treated with a combination of Transurethral bladder resection (TURB) followed by adjuvant intravesical instillation with BCG. Basal characteristics of both groups were analyzed. Times to event of interest (relapse; including recurrence and/or progression) were estimated by survival analysis using the Kaplan-Meier method. Relapse-free survival rates were analyzed using a multivariable Cox regression model of proportional hazards. Results: Median follow-up in the 2019 sample was 503 days and 1197 days in the 2017 group, with a median number of instillations of 8 and 12 respectively. There was a 37.7% proportion of tumoral relapse observed in the 2019 group and 29.03% during 2017. Survival analysis revealed mean relapse-free follow-up of 683 days (95%CI 601.3-765.5) in the 2019 group and of 1359 days (95%CI 1244.3-1474) in 2017. Further analysis using LogRank test revealed observed differences to be statistically significant (p=0.02) Multivariable analysis revealed a proportional Hazard ratio (HR) for relapse-free survival rate of 2.2 (95% CI: 1.13-4.25; p=0.019) regarding the 2019 sample treated with a reduced-dose course. Conclusions: BCG shortage and the subsequent reduced-dose schemes used for intravesical instillation, due to limited availability, had a significant impact on tumor relapse rates during follow-up. These findings are consistent with other published studies and show the need for full-dose BCG courses in order to prevent higher relapse rates after TURB.","PeriodicalId":75487,"journal":{"name":"Anales de la Real Academia Nacional de Medicina","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69672165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Even though an impaired balance between caloric intake and energy expenditure underlies the excessive accumulation of adipose tissue in most cases of childhood and adolescent obesity, there is a high interindividual variability in the susceptibility to develop obesity, which is based largely on each person’s singular genetic background. Advances in our understanding of the latter arise from the progressive unravelling of the pathophysiological bases of the mechanisms involved in the control of appetite, satiety, and energy expenditure. An important body of evidence in this field has derived from the study of an increasing number of cases of obesity with proven genetic (either syndromic or not), endocrinological or secondary etiology. Consequently, we now need to speak in term of «childhood obesities» when referring to the common phenotypic trait of excessive adipose tissue accumulation as the underlying pathophysiological bases are widely different between subjects; thus, individualized diagnostic and management approaches both, for obesity itself as for its associated comorbidities are required. Furthermore, the advances made in identifying patients with monogenic diseases cosegregating with the phenotype of obesity have considerably increased the modern pathophysiological bases of obesity. Therefore, it is imperative to individualize the diagnostic strategy, thus leading to a relevant change in the therapeutic approach. In fact, the results obtained by using the analog of melanocortin, setmelanotide, in patients with POMC (proopiomelanocortin), LEPR (leptin receptor) and PCSK1 (proprotein concertase subtilisin-kexin type 1) deficiency, and more recently studies of the structure and architecture of the MC4R (melanocortin receptor number 4), may allow a more precise analysis of the effects of the loss-of-function mutations in MC4R associated to obesity, as well as structural prediction of their responsiveness to setmelanotide, leading to a personalized therapy based on precision medicine.","PeriodicalId":75487,"journal":{"name":"Anales de la Real Academia Nacional de Medicina","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69672308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Different diseases generate changes in the physiology of the vessel wall. The balance between vasoconstrictor and vasodilator molecules, mainly released by the endothelium, is lost in favor of vasoconstrictors, which in addition to generating an inadequate vasoconstrictor response, induce proliferative changes of different cell lines that modify the structure of the vessel wall, from the hypertrophy of the media until progressive occlusion of the arteriolar beds, formation of angiomatous lesions, micro aneurysms, plexiform lesions, thrombotic occlusions and necrotizing arteritis corresponding to the different degrees of pulmonary hypertension. The symptoms of right ventricular failure, the radiographic and electrocardiographic data of right ventricular growth or dilatation, allow us to suspect the diagnosis that can be confirmed by echocardiography, measuring the peak velocity of the tricuspid regurgitation that corresponds to the systolic pressure of the pulmonary artery. The progressive severity of the lesions allows the treatment to be staggered, including measures to compensate for heart failure with loop diuretics, permanent anticoagulation, and vasodilators such as Calcium Channel Blockers and to greater severity, endothelin antagonists, phosphodiesterase 5 inhibitors, prostacyclin and derivatives and combinations of several of these drugs. The creation of a right to left shunt decompresses the lung bed, reducing pressure, with desaturation and an increase in systemic output, but improving exercise tolerance and survival.","PeriodicalId":75487,"journal":{"name":"Anales de la Real Academia Nacional de Medicina","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69671891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each technique should be adequate to the clinic and evolution time of the injury. Once muscle atrophy is established, nerve repair and nerve transfers do not achieve a good functional result.
