Clinical Verification of Homeopathy

The world is changing! This is certainly true regarding the homeopathic practice and access to homeopathic medicine. Therefore our first priority at the ECH-LMHI [1] has been to produce a yearly report on the scientific framework of homeopathy. In the 2010 version a new chapter about epidemic diseases has been added including the Leptospirosis survey on the Cuban population. A second priority has been to review the definition of the homeopathic medicines respecting the new framework generated by the official registration procedure and the WHO report. We are working now on a documented (Materia Medica and provings) list of homeopathic remedies to facilitate the registration of our remedies. The new challenges are: first of all more good research proposals and as such more funding (possible through ISCHI + Blackie Foundation as examples) [2]; international acceptance of new guidelines for proving and clinical verification of homeopathic symptoms (Proposals are ready for discussion); total reconsideration of the homeopathic repertories including results of the clinical verification of the symptoms. The world is changing, we are part of the world and changes are needed also for homeopathy!

Sociodemographic factors associated with public knowledge of dementia in a Cuban population

ABSTRACT International organizations estimate that a new dementia is diagnosed every 3 s. Objectives: To explore the knowledge and beliefs among a cross-section of the adult population of Cuba with regard to dementia risk factors and to determine the demographic variables related with it. A cross-sectional survey was carried out on 1,004 Cubans. Methods: The survey measured the importance placed on dementia, risk reduction knowledge, and the actions to prevent it. Logistic regression was undertaken to identify variables associated with knowledge. Results: Many respondents (47.5%) believe that dementia risk reduction should start before the age of 40. Cognitive stimulation and physical activities were selected with major frequency. Being older than 48 years, having previous contact with dementia, and university education increases the probability of having healthy lifestyles. Conclusions: The exploration of demographic variables allows the prediction of likelihood to know about or have positive beliefs in relation to dementia. They should be contemplated into strategies for dementia prevention in Cuban population.

Whole genome sequences of Treponema pallidum subsp. endemicum isolated from Cuban patients: the non-clonal character of isolates suggests a persistent human infection rather than a single outbreak

Bejel (endemic syphilis) is a neglected non-venereal disease caused by Treponema pallidum subsp. endemicum (TEN). Although it is mostly present in hot, dry climates, a few cases have been found outside of these areas. The aim of this work was the sequencing and analysis of TEN isolates obtained from "syphilis patients" in Cuba, which is not considered an endemic area for bejel. Genomes were obtained by pool segment genome sequencing or direct sequencing methods, and the bioinformatics analysis was performed according to an established pipeline. We obtained four genomes with 100%, 81.7%, 52.6%, and 21.1% of broad coverage, respectively. The sequenced genomes revealed a non-clonal character, with nucleotide variability ranging between 0.2–10.3 nucleotide substitutions per 100 kbp among the TEN isolates. Nucleotide changes affected 27 genes, and the analysis of the completely sequenced genome also showed a recombination event between tprC and tprI, in TP0488 as well as in the intergenic region between TP0127–TP0129. Despite limitations in the quality of samples affecting broad sequencing coverage, the determined non-clonal character of the isolates suggests a persistent infection in the Cuban population rather than a single outbreak caused by imported case.

Biometry, Refractive Errors, and the Results of Cataract Surgery: A Large Sample Study

The statistical characteristics of biometry and refractive error in a large sample of cataractous Cuban patients are presented, comparing between sexes and age groups. All patients were studied at the Cuban Institute of Ophthalmology “Ramón Pando Ferrer,” La Habana. The sample consists of 28252 eyes of 25068 patients, subjected to cataract surgery during the time period between 2006 and 2019. Their biometry was obtained using IOL Master devices; also, visual acuity, refraction, and corneal power were registered. After surgery, the visual acuity and refraction were measured. The refractive prediction error was determined. For patients with both eyes registered, anisometropia was also calculated. Age and sex were used to segment the data. The preoperative biometric parameters show highly significant differences between sexes, with male eyes being longer and with a deeper anterior chamber but with a thinner lens. Also, keratometry shows highly significant differences, with female eyes being steeper than male. Before surgery, both sexes have myopic eyes as average, with males being more myopic than females ( p < 0.001). After surgery, the average spherical equivalent is −0.36 D and female eyes are more myopic than males ( p < 0.001). Visual acuity with and without distance correction has a significant increase after surgery. These results are of importance not only for Cuba but also for other countries with a large Cuban population and/or similar ethnic composition, such as the USA (particularly the south of Florida), Spain, and many countries in Latin America.

THE PUZZLE OF RACIAL INEQUALITY IN CUBA, 1980s–2010s

Contrasting perspectives on racism and racial inequality collide in contemporary Cuba. On the one hand, government officials argue that Cuba is a racially egalitarian country; though vestiges of historical racism subsist, systematic discrimination does not. On the other hand, social movement actors and organizations denounce that racism and discrimination are systemic and affect large sectors of the Afro-Cuban population. To draw these visions into scholarly dialogue, our analytic strategy consists in the comparative examination of both narratives as well as the empirical bases that sustain them. Using data from the 1981, 2002, and 2012 Cuban Censuses for the first time, as well as various non-census evidentiary sources, both quantitative and qualitative, we examine how racial inequality has evolved in Cuba during the last decades. Our analyses of census data suggest that racial stratification has a limited impact on areas such as education, health care, occupation, and positions of leadership. We find, nonetheless, that an expanding and strikingly racialized private sector is fueling dramatic income inequality by skin color beyond the reach of official census data. Our analysis sheds light on how different data can convey profoundly different pictures of racial inequality in a given context. Moreover, we highlight that significant contradictions can coexist in the lived experiences of racism and racial inequality within a single country context.

Anxiety, Health Self-Perception, and Worry About the Resurgence of COVID-19 Predict Fear Reactions Among Genders in the Cuban Population

The resurgence of COVID-19 could deepen the psychological impacts of the pandemic which poses new challenges for mental health professionals. Among the actions that should be prioritized is the monitoring of the groups that have shown greater psychological vulnerability during the first stage of the pandemic. The first aim of our study is to explore the fear reactions to COVID-19 between genders during the second wave of the outbreak in Cuba. Second, establish possible predictors of fear of COVID-19 in relation to gender. Specifically, we will evaluate how anxiety related to COVID-19, health self-perception, and worry about the resurgence of COVID-19 predict fear reactions among women and men in the Cuban population. A cross-sectional online study was designed. The research was conducted between August 16 and October 18, 2020. A total of 373 people completed the online survey. A socio-demographic questionnaire, the Fear of COVID-19 Scale and the Coronavirus Anxiety Scale were used. An independent-samples t-test was conducted to compare the fear, worry, anxiety and self-perceived health scores, between genders. The relationship between those variables and fear of COVID-19, was investigated using Pearson correlation coefficient. Finally, multiple linear regression was used to evaluate the possible associations (predictors) related to fear of COVID-19. In our study, women, compared to men, presented greater fear reactions, greater concern about resurgence of COVID-19 and poorer self-perceived health. Anxiety reactions in our sample showed no differences between genders. In women, anxiety of COVID-19, worry about resurgence of COVID-19, and self-perceived health are associated with fear reactions to COVID-19. In the case of men, the self-perceived health showed no associations with fear reactions. Our results confirm the results of several related investigations during the first wave of the pandemic where women have shown greater psychological vulnerability compared to men. However, we cannot rule out that the real impact of the pandemic on mental health in men is much greater than that described by the studies conducted to date. Additional studies are needed on the psychological impact of COVID-19 on men.
