Resultados: Se exponen los hallazgos del diagnóstico y caracterización de la situación problémica. Se aplicaron técnicas e instrumentos de investigación a pacientes, familiares y personal de salud. Se constataron insuficiencias que limitan el intercambio discursivo lo cual redunda en estados de insatisfacción que atentan contra el propósito de la interrelación en el proceso de la atención en salud. Discusión: Los resultados confrontados con investigaciones nacionales y extranjeras confirman la justificación del problema científico y la actualidad de la temática.

Introduction: Social relations are built on the basis of communication between men and from the professional point of view they imply the mastery of communicative competence that guarantees the possession of knowledge that strengthens the result of the exchange between the interlocutors. The objective of the text is to present the initial results of the process of characterization and diagnosis of the problematic situation assumed by the research project Overcoming strategy aimed at the development of professional communicative competence in the context of the personal health-patient relationship at the level primary care. Method: It is a sectorial investigation of the Research + Development type that, due to its nature, is explanatory-causal observational. It is managed at the Center for the Development of Social and Humanistic Sciences in Health. (CENDECSA), attached to the University of Medical Sciences of Camagüey; between January 2021 and December 2023. The quasi-experimental study, with a pre- and post-intervention design, uses a simple random sample, made up of professionals from the José Martí University Polyclinic, as well as cons from the territory who participate in the actions of overcoming that are undertaken. Results: The findings of the diagnosis and characterization of the problematic situation are exposed. Research techniques and instruments were applied to patients, relatives and health personnel. Insufficiencies were found that limit the discursive exchange, which results in states of dissatisfaction that undermine the purpose of interrelation in the health care process. Discussion: The results compared with national and foreign investigations confirm the justification of the scientific problem and the topicality of the subject.

A simple score to predict early severe infections in patients with newly diagnosed multiple myeloma.

Infections remain a common complication in patients with multiple myeloma (MM) and are associated with morbidity and mortality. A risk score to predict the probability of early severe infection could help to identify the patients that would benefit from preventive measures. We undertook a post hoc analysis of infections in four clinical trials from the Spanish Myeloma Group, involving a total of 1347 patients (847 transplant candidates). Regarding the GEM2010 > 65 trial, antibiotic prophylaxis was mandatory, so we excluded it from the final analysis. The incidence of severe infection episodes within the first 6 months was 13.8%, and majority of the patients experiencing the first episode before 4 months (11.1%). 1.2% of patients died because of infections within the first 6 months (1% before 4 months). Variables associated with increased risk of severe infection in the first 4 months included serum albumin ≤30 g/L, ECOG > 1, male sex, and non-IgA type MM. A simple risk score with these variables facilitated the identification of three risk groups with different probabilities of severe infection within the first 4 months: low-risk (score 0-2) 8.2%; intermediate-risk (score 3) 19.2%; and high-risk (score 4) 28.3%. Patients with intermediate/high risk could be candidates for prophylactic antibiotic therapies.

ABSTRACT Background: the COVID 19 pandemic causes the death of many people, mainly older adults. Knowing about it is one way to prevent it. Objective: to describe the results of an educational intervention on COVId 19, in older adults Methods: educational intervention carried out in a universe of 230 older adults, from which a sample of 178 dispensed elderly people belonging to the Family Doctor´s Office No. 4 in Cumanayagua was selected. A diagnosis was made to identify the level of knowledge about COVID-19, in which aspects about the disease were investigated, such as: symptoms, prevention measures, transmission routes. They were also asked about compliance with prevention measures. On that basis, an educational intervention was developed. Results: The 50 % present risk factors; knowledge about symptoms increased from 10.1% before the intervention to 100% after; on transmission routes from 35.9 % to 83.7 % and that of preventive measures from 53.9 % to 91.7 %. They learned to use the mask correctly. The satisfaction of the elderly with the educational actions was high. Conclusions: after the application of educational actions, there was an increase in knowledge about the disease, which may be favorable for its prevention in this group of elderly.

Intracranial calcifications associated with epilepsy: A case report of lipoid proteinosis.

Lipoid proteinosis (LP) is a very rare autosomal-recessive disease characterized by multisystem involvement due to intracellular deposition of amorphous hyaline material. Clinical manifestations include hoarness, acne-like facial scarring and neurological manifestation including seizures. We describe the clinical, genetics and radiological features of LP in a refractory epileptic patient with genetic confirmation.

High serum IL-6 values increase the risk of mortality and the severity of pneumonia in patients diagnosed with COVID-19.

The clinical presentation of COVID-19 is very heterogeneous, ranging from asymptomatic to severe, which could lead to the need for mechanical ventilation or even death.We analyzed the serum levels of IL-6 in patients with COVID-19 diagnosis and its relationship with the severity of the disease, the need for mechanical ventilation and with patient mortality. We assessed IL-6 in a cohort of 50 patients diagnosed with COVID-19 pneumonia with different degrees of disease severity, and compared it with clinical and laboratory findings. We found higher levels of IL-6 in patients with more severe pneumonia according to CURB-65 scale (p = 0.001), with ICU mechanical ventilation requirements (p = 0.02), and who subsequently died (p = 0.003). Of the clinical and analytical parameters analyzed in the current study, the serum levels of IL-6 was the most effective predictor of disease severity. From the data obtained in ROC curve analysis, we defined a cut-off point for serum IL-6 levels of 35 pg/mL above which both the risk of mortality (OR = 20.00, 95 % CI 4.214-94-912, p = 0.0001) and ICU admission (OR = 12.750, 95 % CI 2,159-75,3,3, p = 0.005) were increased. Starting from blood IL-6 levels 27 out of 50 patients, with high levels and more severe symptoms, were treated with the IL-6 receptor antagonist Tocilizumab. IL-6 serum levels appear to be a useful prognostic biomarker in patients with a diagnosis of COVID-19 pneumonia. A cut-off point of 35 pg/mL could clearly differentiate patients a with more severe disease.

Factores biológicos y sociales que influyen en la salud de la mujer durante el climaterio y la menopausia / Biological and social factors that influence women's health during climacteric and menopause

RESUMEN La menopausia es una tapa en la vida de la mujer sujeta a muchos cambios. Se sabe que es el cese completo de la menstruación, pero a menudo se menosprecian los síntomas producidos por esta, incluso por el personal de salud. A través de diferentes épocas, ha sido motivo de menciones históricas, literarias, culturales, etc. Alrededor del climaterio y la menopausia existen muchos factores que la condicionan. El objetivo de esta revisión es compilar información sobre los aspectos biológicos y sociales que influyen en la salud de la mujer en esta etapa de su vida.

ABSTRACT Menopause is a period in a woman's life subject to many changes. It is known that it is the complete cessation of menstruation, but the symptoms produced by it are often underestimated, even by health personnel. Through time, it has been mentioned in history, literature, culture, etc. There are many factors which condition the climacteric and menopause. The objective of this review is to compile information on the biological and social aspects that influence women´s health at this stage of their lives.

Predicting long-term disease control in transplant-ineligible patients with multiple myeloma: impact of an MGUS-like signature.

Disease control at 5 years would be a desirable endpoint for elderly multiple myeloma (MM) patients, but biomarkers predicting this are not defined. Therefore, to gain further insights in this endpoint, a population of 498 newly diagnosed transplant-ineligible patients enrolled in two Spanish trials (GEM2005MAS65 and GEM2010MAS65), has been analyzed. Among the 435 patients included in this post-hoc study, 18.6% remained alive and progression free after 5 years of treatment initiation. In these patients, overall survival (OS) rate at 10 years was 60.8% as compared with 11.8% for those progressing within the first 5 years. Hemoglobin (Hb) ≥ 12 g/dl (OR 2.74, p = 0.001) and MGUS-like profile (OR 4.18, p = 0.005) were the two baseline variables associated with long-term disease-free survival. Upon including depth of response (and MRD), Hb ≥ 12 g/dl (OR 2.27) and MGUS-like signature (OR 7.48) retained their predictive value along with MRD negativity (OR 5.18). This study shows that despite the use of novel agents, the probability of disease control at 5 years is still restricted to a small fraction (18.6%) of elderly MM patients. Since this endpoint is associated with higher rates of OS, this study provides important information about diagnostic and post-treatment biomarkers helpful in predicting the likelihood of disease control at 5 years.

Early myeloma-related death in elderly patients: development of a clinical prognostic score and evaluation of response sustainability role.

Although survival of elderly myeloma patients has significantly improved there is still a subset of patients who, despite being fit and achieving optimal responses, will die within 2 years of diagnosis due to myeloma progression. The objective of this study was to define a scoring prognostic index to identify this group of patients. We have evaluated the outcome of 490 newly diagnosed elderly myeloma patients included in two Spanish trials (GEM2005-GEM2010). Sixty-eight patients (13.8%) died within 2 years of diagnosis (early deaths) due to myeloma progression. Our study shows that the use of simple scoring model based on 4 widely available markers (elevated LDH, ISS 3, high risk CA or >75 years) can contribute to identify up-front these patients. Moreover, unsustained response (<6 months duration) emerged as one important predictor of early myeloma-related mortality associated with a significant increase in the risk of death related to myeloma progression. The identification of these patients at high risk of early death is relevant for innovative trials aiming to maintain the depth of first response, since many of them will not receive subsequent lines of therapy.

Maltrato infantil y la atención en el nivel primario de salud / Child abuse and primary health care attention

El presente texto se inscribe dentro de la temática dirigida a la investigación sobre la violencia intrafamiliar. Tiene como objetivo sistematizar aspectos históricos y teóricos inherentes al estudio del maltrato infantil y sus consecuencias en el ámbito social y familiar para su detección y tratamiento en el nivel de atención primaria de los servicios de salud en Cuba. Mediante una revisión bibliográfica se logró concretar un análisis documental de materiales y textos en soporte digital e impreso que condujo a los acercamientos teórico e histórico del fenómeno en el ámbito internacional y nacional, para su conceptualización, la determinación de su tipología y el establecimiento de sus consecuencias; elementos imprescindibles del saber profesional del futuro egresado de las ciencias médicas, en función de su desempeño en los diferentes niveles de atención de salud, en especial, la atención primaria.

The text falls within the research on intrafamiliar violence subject matter. Its objective is to systematize historical and theoretical aspects inherent to the study of child abuse and its consequences within the social and domestic scopes for its detection and treatment in the Cuban primary health care services. By means of a bibliographic review, a documentary analysis of electronic and printed form materials and texts was summarized. It led to theoretical and historical approaches to the phenomenon within the national and international scopes for its conceptualization, the establishment of its typology and consequences. They are essential elements of the professional knowledge of future medical sciences graduates towards their performance in different health care levels, especially in primary health care.

Minimal residual disease monitoring and immune profiling in multiple myeloma in elderly patients.

The value of minimal residual disease (MRD) in multiple myeloma (MM) has been more frequently investigated in transplant-eligible patients than in elderly patients. Because an optimal balance between treatment efficacy and toxicity is of utmost importance in patients with elderly MM, sensitive MRD monitoring might be particularly valuable in this patient population. Here, we used second-generation 8-color multiparameter-flow cytometry (MFC) to monitor MRD in 162 transplant-ineligible MM patients enrolled in the PETHEMA/GEM2010MAS65 study. The transition from first- to second-generation MFC resulted in increased sensitivity and allowed us to identify 3 patient groups according to MRD levels: MRD negative (<10(-5); n = 54, 34%), MRD positive (between <10(-4) and ≥10(-5); n = 20, 12%), and MRD positive (≥10(-4); n = 88, 54%). MRD status was an independent prognostic factor for time to progression (TTP) (hazard ratio [HR], 2.7; P = .007) and overall survival (OS) (HR, 3.1; P = .04), with significant benefit for MRD-negative patients (median TTP not reached, 70% OS at 3 years), and similar poorer outcomes for cases with MRD levels between <10(-4) and ≥10(-5) vs ≥10(-4) (both with a median TTP of 15 months; 63% and 55% OS at 3 years, respectively). Furthermore, MRD negativity significantly improved TTP of patients >75 years (HR, 4.8; P < .001), as well as those with high-risk cytogenetics (HR, 12.6; P = .01). Using second-generation MFC, immune profiling concomitant to MRD monitoring also contributed to identify patients with poor, intermediate, and favorable outcomes (25%, 61%, and 100% OS at 3 years, respectively; P = .01), the later patients being characterized by an increased compartment of mature B cells. Our results show that similarly to transplant candidates, MRD monitoring is one of the most relevant prognostic factors in elderly MM patients, irrespectively of age or cytogenetic risk. This trial was registered at www.clinicaltrials.gov as #NCT01237249.

Agreement of skin test with IL-4 production and CD40L expression by T cells upon immunotherapy of subjects with systemic reactions to Hymenoptera stings.

Venom immunotherapy is the only curative intervention for subjects with Hymenoptera venom allergy who suffering systemic reactions upon bee or wasp stings. Venom immunotherapy can restore normal immunity against venom allergens, as well as providing to allergic subjects a lifetime tolerance against venoms. Nevertheless, it is necessary using safety assays to monitoring the development of tolerance in the VIT protocols to avoid fatal anaphylactic reactions. The purpose of this study was to assess the modifications in several markers of tolerance induction in subjects with Hymenoptera venom allergy undergoing immunotherapy. The studies were performed at baseline time and after six month of VIT. Intradermal skin tests, basophil activation tests, specific IgE levels; and the T-cell markers (IL-4 and IFN-γ producing cells; and expression of the surface activation markers CD40L and CTLA-4) were assayed. At six month of immunotherapy all parameters studied had significant alterations. All decreased, except the IFN-γ producing cells. In addition, modifications in intradermal skin test showed a significant correlation with both, CD40L expression on CD4 T lymphocytes (p=0.043) and IL-4 producing T lymphocytes (p=0.012). Neither basophil activation test nor serum levels of sIgE demonstrated any correlation with the immunological parameters studied nor among them. These results suggest that both IL-4 production and CD40L expression could be two good indicators of the beneficial effects of venom immunotherapy which translate into skin tests.

Sequential vs alternating administration of VMP and Rd in elderly patients with newly diagnosed MM.

Bortezomib plus melphalan and prednisone (VMP) and lenalidomide plus low-dose dexamethasone (Rd) are 2 standards of care for elderly untreated multiple myeloma (MM) patients. We planned to use VMP and Rd for 18 cycles in a sequential or alternating scheme. Patients (233) with untreated MM, >65 years, were randomized to receive 9 cycles of VMP followed by 9 cycles of Rd (sequential scheme; n = 118) vs 1 cycle of VMP followed by 1 cycle of Rd, and so on, up to 18 cycles (alternating scheme; n = 115). VMP consisted of one 6-week cycle of bortezomib using a biweekly schedule, followed by eight 5-week cycles of once-weekly VMP. Rd included nine 4-week cycles of Rd. The primary end points were 18-month progression free survival (PFS) and safety profile of both schemes. The 18-month PFS was 74% and 80% in the sequential and alternating arms, respectively (P = .21). The sequential and alternating groups exhibited similar hematologic and nonhematologic toxicity. Both arms yielded similar complete response rate (42% and 40%), median PFS (32 months vs 34 months, P = .65), and 3-year overall survival (72% vs 74%, P = .63). The benefit of both schemes was remarkable in patients aged 65 to 75 years. In addition, achieving complete and immunophenotypic response was associated with better outcome. The present approach, based on VMP and Rd, is associated with high efficacy and acceptable toxicity profile with no differences between the sequential and alternating regimens. This trial was registered at www.clinicaltrials.gov as #NCT00443235.

Influence of MBL-2 mutations in the infection risk of patients with follicular lymphoma treated with rituximab, fludarabine, and cyclophosphamide.

The employment of current treatments based on chemotherapy and immunotherapy leads to inmunosuppression. The presence of mutations or polymorphisms in genes related to immune system might involve an additional disadvantage. The aim of the present study was to analyze mannose-binding lectin (MBL-2 gene) mutations and their association with severe infections and event-free survival in patients diagnosed with follicular lymphoma, treated uniformly, in the clinical trial LNHF-03. The results of this trial showed impressive clinical efficacy but was complicated with 80 documented infectious episodes. Patients were classified into two genotypic groups, AA and AO/OO, based on their haplotypic inheritance. Neither the number of infectious episodes nor differences in event-free survival was found as a function of MBL-2 groups. Other factors, including the lymphoma malignancy and the immune alterations associated with the disease, should be considered responsible for this observation.

Total loss of HLA class I expression on a melanoma cell line after growth in nude mice in absence of autologous antitumor immune response.

Loss of HLA class I expression on tumor cells is a frequent event as an immune escape mechanism. Seven different altered HLA phenotypes have been defined in tumors. Various molecular mechanisms have been described as responsible for HLA class I loss. HLA class I expression alterations occur successively and unpredictably during tumor progression in vivo and immunoselection has been implicated in this process. We present an experimental xenograft model in which melanoma cell line Ando-2 injected into athymic nude mice lost total surface HLA class I expression and exhibited HLA class II cell surface expression. A strong down-regulation of HLA class I expression and de novo HLA class II expression were also found when Ando-2 melanoma cells were injected into SCID-Beige mice. These phenomena were reproducible and were only observed in local growth in nude or SCID-Beige mice and not in vitro after multiple passages. HLA class I surface expression was recovered after IFN-gamma treatment, indicating regulatory defects. The mechanism implicated in loss of HLA class I molecule expression were a down-regulation of different components of antigen processing machinery and HLA class I heavy chains. These data suggest that HLA class I alterations can also occur in absence of autologous adaptive immune response. This is a good experimental in vivo model to study the relationship between tumor progression and HLA class I alterations.

Conventional and molecular cytogenetic diagnostic methods in stem cell research: a concise review.

Regenerative medicine and cell therapy are emerging clinical disciplines in the field of stem cell biology. The most important sources for cell transplantation are human embryonic and adult stem cells. The future use of these human stem cell lines in humans requires a guarantee of exhaustive control with respect to quality control, safety and traceability. Genetic instability and chromosomal abnormalities represent a potential weakness in basic studies and future therapeutic applications based on these stem cell lines, and may explain, at least in part, their usual tumourigenic properties. So, the introduction of the cytogenetic programme in the determination of the chromosomal stability is a key point in the establishment of the stem cell lines. The aim of this review is to provide readers with an up-to-date overview of all the cytogenetic techniques, both conventional methods and molecular fluorescence methods, to be used in a stem cell bank or other stem cell research centres. Thus, it is crucial to optimize and validate their use in the determination of the chromosomal stability of these stem cell lines, and assess the advantages and limitations of these cutting-edge cytogenetic technologies.

Evaluation of a laser technique to isolate the inner cell mass of murine blastocysts.

hESCs (human embryonic stem cells) are pluripotent cells derived from the ICM (inner cell mass) of blastocysts that can be used to derive several kinds of cells of the human body for the treatment of some previously untreated diseases. In considering the future use of hESCs in regenerative medicine and cell-therapy programmes, several research centres have begun projects involving the derivation of hESC lines using spare human embryos from IVF (in vitro fertilization) cycles. In some stem-cell banks, such as ours, the law also permits us to obtain these cell lines. The low availability of spare IVF human embryos, and the low rate of success in the derivation of hESC lines, give these embryos a great research value that limits experiments with new techniques. The use of murine embryos would be a good model with which to do research to discover the best methodologies to use in order to derive new hESC lines. The aim of the present study was to evaluate a new method of isolation of the ICM and derivation of ESC lines in a murine blastocyst model using laser drilling to eliminate the trophectoderm cells and compare it with the usual control method consisting of culturing the whole murine blastocyst. We also tested the adhesion and growth of primary colonies of mESCs (murine ESCs) over two different growth surfaces, namely an MEF (inactive murine fibroblastic feeder layer) or gelatin-coated dishes, in order to achieve the best culture conditions for future derivation of human stem-cell lines for application in human transplantation.

Beneficial effects of green tea--a review.

Tea is the most consumed drink in the world after water. Green tea is a 'non-fermented' tea, and contains more catechins, than black tea or oolong tea. Catechins are in vitro and in vivo strong antioxidants. In addition, its content of certain minerals and vitamins increases the antioxidant potential of this type of tea. Since ancient times, green tea has been considered by the traditional Chinese medicine as a healthful beverage. Recent human studies suggest that green tea may contribute to a reduction in the risk of cardiovascular disease and some forms of cancer, as well as to the promotion of oral health and other physiological functions such as anti-hypertensive effect, body weight control, antibacterial and antivirasic activity, solar ultraviolet protection, bone mineral density increase, anti-fibrotic properties, and neuroprotective power. Increasing interest in its health benefits has led to the inclusion of green tea in the group of beverages with functional properties. However, although all the evidence from research on green tea is very promising, future studies are necessary to fully understand its contributions to human health, and advise its regular consumption in Western diets, in which green tea consumption is nowadays limited and sporadic.
