Research challenges and opportunities in the Caribbean area: first bibliometric study in the French West Indies, from 1989 to 2018.

OBJECTIVE: To analyze, describe, and quantify the collaborations and scientific output of the two university teaching hospitals of Martinique and Guadeloupe, at the regional, national, and international level. METHODS: A bibliometrics analysis was performed from the international databases Web of Science and PubMed, for the period from 1989 to 2018, inclusive (30 years). Three types of bibliometric indicators were used, namely quantitative indicators, performance indicators, and organization-specific indicators. Affiliations of the first and last authors were identified from PubMed. RESULTS: Between 1989 and 2018, a total of 1 522 indexed articles were published with at least one author affiliated to either the University Hospital of Martinique (n = 827) or the University Hospital of Guadeloupe (n = 685). The majority of articles were in category Q1 (35.8% for Martinique and 35.2% for Guadeloupe). In Martinique, over the last 30 years, the three main research areas have been clinical neurology, ophthalmology, and surgery, together representing 28.7% of all research areas, with the highest number of articles published in the field of clinical neurology (n = 81). In the University Hospital of Guadeloupe, the area of hematology was largely represented, with 79 articles published. For both hospitals, the first and last authors of the articles published were mainly from mainland France. CONCLUSIONS: This quantitative analysis shows the development of medical and scientific research in Martinique and Guadeloupe over the last three decades, as well as the extent of their collaborative partnerships at the national and international levels.

International cooperation in public health in Martinique: geostrategic utility for cancer surveillance in the Caribbean.

BACKGROUND: Cooperation in public health and in oncology in particular, is currently a major issue for the island of Martinique, given its geopolitical position in the Caribbean region. The region of Martinique shares certain public health problems with other countries of the Caribbean, notably in terms of diagnostic and therapeutic management of patients with cancer. We present here a roadmap of cooperation priorities and activities in cancer surveillance and oncology in Martinique. MAIN BODY: The fight against cancer is a key public health priority that features high on the regional health policy for Martinique. In the face of these specific epidemiological conditions, Martinique needs to engage in medical cooperation in the field of oncology within the Caribbean, to improve skills and knowledge in this field, and to promote the creation of bilateral relations that will help to improve cancer management in an international healthcare environment. CONCLUSIONS: These collaborative exchanges will continue throughout 2020 and will lead to the implementation of mutual research projects across a larger population basin, integrating e-health approaches and epidemiological e-cohorts.

Impact of Preoperative Iron Deficiency on Blood Transfusion in Elective Cardiac Surgery.

OBJECTIVE: To evaluate the incidence and consequences of preoperative iron deficiency in elective cardiac surgery. DESIGN: A prospective observational study. SETTING: The cardiac surgery unit of a university hospital, from November 2016 to February 2017. PARTICIPANTS: All patients presenting for elective cardiac surgery during the study period, with the exclusion of noncardiac thoracic surgeries, surgeries of the descending aorta, endovascular procedures, and patients affected by an iron-metabolism disease. INTERVENTIONS: Transferrin saturation and serum ferritin levels were systematically assessed before surgery, and the care of patients was maintained as usual. MEASUREMENTS AND MAIN RESULTS: Routine analyses, clinical data, and the number of blood transfusions were recorded during the hospital stay. Among the 272 patients included, 31% had preoperative iron deficiency and 13% were anemic. Patients with iron deficiency had significantly lower hemoglobin levels throughout the hospital stay and received blood transfusions more frequently during surgical procedures (31% v 19%, p = 0.0361). Detailed analysis showed that patients with iron deficiency received more red blood cell units. There were no differences in postoperative bleeding, morbidity, or mortality. CONCLUSIONS: Iron deficiency appears to be related to lower hemoglobin levels and more frequent transfusions in elective cardiac surgery. Assessing iron status preoperatively and correcting any iron deficiencies should be one of the numerous actions involved in patient blood management for such surgeries, with the aim of reducing morbidity associated with both anemia and transfusion.

Retrieving the Vital Status of Patients with Cancer Using Online Obituaries.

The aim of this study was to develop a methodology to link mortality data from Internet sources with administrative data from electronic health records and to assess the performance of different record linkage methods. We extracted the electronic health records of all adult patients hospitalized at Rennes comprehensive cancer center between January 1, 2010 and December 31, 2015 and separated them in two groups (training and test set). We also extracted all available online obituaries from the most exhaustive French funeral home website using web scraping techniques. We used and evaluated three different algorithms (deterministic, approximate deterministic and probabilistic) to link the patients' records with online obituaries. We optimized the algorithms using the training set and then evaluated them in the test set. The overall precision was between 98 and 100%. The three classification algorithms performed better for men than women. The probabilistic classification decreased the number of manual reviews, but slightly increased the number of false negatives. To address the problem of long delays in the publication or sharing of mortality data, online obituary data could be considered for real-time surveillance of mortality in patients with cancer because they are easily available and time-efficient.

The Role of Percutaneous Biopsy and Prognostic Factors of Malignancy in Solitary Breast Papilloma: A Retrospective Multicenter Study of 259 Cases.

AIM: Management of papillary breast lesions is a controversial issue, as complete excision implies surgery of numerous benign lesions. The purpose of this study was to assess concordance between percutaneous and surgical biopsy of papillomas along with factors predictive of malignancy. PATIENTS AND METHODS: The study consisted of a retrospective review of papilloma cases between 2009 and 2013 at three breast cancer centers. All cases of papilloma histologically diagnosed by percutaneous biopsy and confirmed by surgical specimen were included. The biopsy results were compared with final surgical pathology. Lesion size and clinical and radiological features were recorded. RESULTS: A total of 259 cases were included (188 simple and 71 complex papillomas). Concordance between histology after percutaneous and surgical biopsy was lower for complex papillomas, regardless of type, than for simple papillomas (p<0.001). The risk of having a complex papilloma was shown to be significantly higher in postmenopausal patients (p=0.023), and was 20 times higher if the percutaneous biopsy was malignant as opposed to benign (p<2.10). However, the false-negatives for percutaneous biopsy in complex papilloma cases were mainly related to atypical and in situ lesions. CONCLUSION: Percutaneous biopsy does not appear adequate for identifying papillomas requiring surgical excision due to the risk of underestimation of cancerous lesions. However, certain factors predictive of malignancy may assist with surgical management, such as age and menopausal status, lesions peripheral to the nipple, and atypia on percutaneous biopsy.
