Oral and general health conditions involved in periodontal status during pregnancy: a prospective cohort study.

PURPOSE: Pregnancy is a period in a woman's life that has important consequences on oral health, particularly for gingival health. Present study aims to identify women at higher risk of developing periodontal disease (gingivitis and periodontitis) during late pregnancy and evaluate how this condition evolves during this period. METHODS: Prospective cohort study was designed with pregnant women who were assessed during the first and third trimesters of gestation in a southern Spanish public hospital. Data regarding gingival and periodontal health, oral hygiene, and overall health status (obesity and diabetes mellitus) were collected. Reporting followed STROBE checklist. RESULTS: Significantly higher number of women had the periodontal and gingival disease in the third trimester of gestation compared with in early pregnancy. In the third trimester of gestation, 42 (28.6%) and 63 (42.9%) of women presented symptoms of periodontal disease and gingival disease, respectively. Obesity (OR 2.834; 95%CI 0.919-8.741), worse oral hygiene during the first trimester of gestation (OR: 4.031; 95%CI 2.12-7.65), and periodontal disease during early pregnancy (OR: 15.104; 95%CI 3.60-63.36) most effectively predicted periodontal disease during late pregnancy. CONCLUSIONS: Pregnancy is associated with exacerbated periodontal and gingival disease symptoms throughout the different trimesters of gestation. Obesity and oral hygiene during early pregnancy were the risk factors that most contributed to the aforementioned changes in periodontal disease.

Future robust studies with different designs in distinct populations are needed to enlarge on these findings.(AU)

Asociación entre la dieta de la población vegana y la autopercepción del estado periodontal en Lima Metropolitana / Association between diet of the vegan population and self-perception of periodontal state in Metropolitan Lima

Objetivo: determinar la asociación entre la dieta vegana y la autopercepción del estado periodontal en una población vegana de Lima Metropolitana, Perú. Materiales y métodos: un total de 240 personas (120 veganas y 120 no veganas) fueron encuestadas en este estudio durante los meses de agosto a diciembre del año 2020 de manera virtual. Para evaluar la autopercepción del estado periodontal y los hábitos de higiene oral se utilizó el autorreporte de enfermedad periodontal, que se encuentra validado con una alfa de Cronbach de 0,77. Además se registraron otras variables como la edad, el sexo, el nivel socioeconómico, el grado de estudio y el consumo de tabaco. Se utilizó la regresión de Poisson con estimador robusto de la varianza para la asociación de las variables y se reportaron razones de prevalencia en un modelo crudo y ajustado. El nivel de confianza fue del 95 % y el de significancia fue de p < 0,05. Resultados y conclusiones: se encontró asociación estadísticamente significativa entre la apariencia de encías rojizas y/o hinchadas (RP = 0,67; IC 95 %: 0,25-0,54) y la mala percepción del estado de las encías (RP = 0,43; IC 95 %: 0,33-0,56) con la dieta vegana. Por último, para la dimensión del sangrado de encías durante el cepillado no se observaron diferencias estadísticamente significativas entre las personas veganas y las no veganas (AU)

Objective: to determine the association between vegan diet and self-perceived periodontal status in a vegan population of Metropolitan Lima, Peru. Materials and methods: a total of 240 people (120 vegans and 120 non-vegans) were surveyed in this study during the months of August to December 2020 in a virtual way. To evaluate self-perception of periodontal status and oral hygiene habits, the self-report of periodontal disease was used, which is validated with a Cronbach's alpha of 0.77. In addition, other variables such as age, sex, socioeconomic level, educational level, and tobacco consumption were registered. A Poisson regression with robust variance estimator was used both for the association of variables, and prevalence ratios were reported in a crude and adjusted model. The confidence level was 95 % and the significance level was p < 0.05. Results and conclusions: a statistically significant association was found between the appearance of reddish and/or swollen gums (PR = 0.67; 95 % CI: 0.25-0.54) and poor perception of the state of the gums (PR = 0.43; 95 % CI: 0.33-0.56) with the vegan diet. Finally, for the gum bleeding dimension during brushing, no statistically significant differences were observed between vegans and non-vegans (AU)

Factors associated with oral health-related quality of life during pregnancy: a prospective observational study.

PURPOSE: To evaluate the evolution of perceived quality of life in relation to oral health during pregnancy and to determine the risk factors involved in this process. METHODS: A follow-up study was carried out with pregnant Spanish women. Two oral examinations and an oral health-related quality of life (OHRQoL) assessment, using the OHIP-14 questionnaire, were performed in the first and third trimester of pregnancy. Data on sociodemographic characteristics, medical history, O'Sullivan Test measures, oral hygiene habits, history of caries, and periodontal status of participants were collected through structured medical-dental questionnaires. RESULTS: A complete dataset comprising 246 pregnant women was available for analysis. Overall scores for negative impacts on the OHIP questionnaire were significantly higher during late pregnancy (74%). This indicated a deterioration in oral health-related quality of life amongst participants. Items describing "painful aching", "self-consciousness", "unsatisfactory diet", and "interrupted meals" showed the greatest increase between the first and third trimester of gestation. Multivariate analysis showed that pre-gestational/gestational diabetes mellitus and poor oral hygiene habits during the first trimester of gestation were directly associated with worse oral health-related quality of life during the third trimester of gestation (hyperglycemia: OR 2.86; 95% CI 1.019-8.050: p = 0.043 / oral hygiene: OR 1.33; 95% CI 0.970-1.836; p = 0.076). CONCLUSIONS: In the present research, hyperglycemia during pregnancy and poor oral hygiene habits during the first trimester of gestation led to a higher risk of poor oral quality of life during late pregnancy.

Presence of bacterial DNA in thrombotic material of patients with myocardial infarction.

Infectious agents have been suggested to be involved in etiopathogenesis of Acute Coronary Syndrome (ACS). However, the relationship between bacterial infection and acute myocardial infarction (AMI) has not yet been completely clarified. The objective of this study is to detect bacterial DNA in thrombotic material of patients with ACS with ST-segment elevation (STEMI) treated with Primary Percutaneous Coronary Intervention (PPCI). We studied 109 consecutive patients with STEMI, who underwent thrombus aspiration and arterial peripheral blood sampling. Testing for bacterial DNA was performed by probe-based real-time Polymerase Chain Reaction (PCR). 12 probes and primers were used for the detection of Aggregatibacter actinomycetemcomitans, Chlamydia pneumoniae, viridans group streptococci, Porphyromonas gingivalis, Fusobacterium nucleatum, Tannarella forsythia, Treponema denticola, Helycobacter pylori, Mycoplasma pneumoniae, Staphylococus aureus,  Prevotella intermedia and Streptococcus mutans. Thus, DNA of four species of bacteria was detected in 10 of the 109 patients studied. The most frequent species was viridans group streptococci (6 patients, 5.5%), followed by Staphylococus aureus (2 patients, 1.8%). Moreover, a patient had DNA of Porphyromonas gingivalis (0.9%); and another patient had DNA of Prevotella intermedia (0.9%). Bacterial DNA was not detected in peripheral blood of any of our patients. In conclusion, DNA of four species of endodontic and periodontal bacteria was detected in thrombotic material of 10 STEMI patients. Bacterial DNA was not detected in the peripheral blood of patients with bacterial DNA in their thrombotic material. Bacteria could be latently present in plaques and might play a role in plaque instability and thrombus formation leading to ACS.

Colonización bacteriana de las cánulas de succión en cirugía ortopédica / Bacterial colonisation of suction cannulas in orthopaedic surgery

INTRODUCCIÓN: Las infecciones osteoarticulares representan una complicación mayor en cirugía ortopédica. Se pretende identificar el porcentaje de cánulas de succión colonizadas y determinar la relación entre el tiempo de uso en cirugía y la colonización de estas. MATERIALES Y MÉTODOS: Estudio descriptivo y prospectivo que analiza 546 cánulas de succión utilizadas en cirugía ortopédica limpia en un centro de trauma, entre noviembre del 2017 a marzo del 2018. El extremo distal de la cánula fue cultivado para determinar la proporción de colonización. RESULTADOS: El 7,3% de las cánulas cultivadas tuvieron cultivos positivos para gérmenes patógenos, de los cuales el más frecuente fue Staphylococcus epidermidis con 27,5%. Además, se encontró asociación entre la colonización y el tiempo de uso de la cánula. La posibilidad de colonización de cánulas usadas entre 60 minutos o más, es mayor que en las que se usaron menos de 60 minutos; entre 60 y 90 minutos la posibilidad es dos veces mayor OR= 2,2 (IC:95% 1,1 - 4,1) y en las cánulas usadas por más de 90 minutos es 8 veces mayor OR= 8,49 (IC:95% 1,77 - 40,86). CONCLUSIONES: La proporción de colonización de las cánulas es menor a lo reportado en la literatura. El mayor tiempo de uso de la cánula en la cirugía aumenta el riesgo de la colonización de estas. Se considera realizar estudios de seguimiento para determinar si la colonización de las cánulas de succión se asocia a un incremento de infección postoperatoria

INTRODUCTION: Osteoarticular infections represent a major complication in orthopaedic surgery. The aim is to identify the percentage of suction cannulas colonised and to determine the relationship between the time they are used in surgery and the colonisation of these cannulas. MATERIALS AND METHODS: Descriptive and prospective study that analysed 546 suction cannulas used in clean orthopaedic surgery in a trauma centre, between November 2017 and March 2018. The distal end of the cannula was cultured to determine the colonisation rate. RESULTS: 7.3% of the cultured cannulas were positive for pathogens, the most frequent being Staphylococcus epidermidis at 27.5%. In addition, an association was found between colonisation and the length of time the cannula was used. The possibility of colonisation of cannulas used for between 60minutes or more, is greater than those used for less than 60 minutes; between 60 and 90 minutes the possibility is twice as high OR= 2.2 (CI:95% 1.1 - 4.1) and in cannulas used for more than 90 minutes it is 8 times higher OR= 8.49 (CI:95% 1.77 - 40.86). CONCLUSIONS: The colonisation rate of cannulas is lower than reported in the literature. The longer the cannula is used in surgery increases the risk of their colonisation. Follow-up studies are being considered to determine whether suction cannula colonisation is associated with increased postoperative infection

Vitamin D, preeclampsia and prematurity: A systematic review and meta-analysis of observational and interventional studies.

BACKGROUND: Vitamin D has important functions outside of bone metabolism. Deficiency has been associated with several adverse outcomes during pregnancy such as preeclampsia and prematurity. There is an increasing body of literature on this topic with studies performed to date having produced contradictory results. OBJECTIVE: To synthesize the literature about vitamin D deficiency and its association with preeclampsia and prematurity in order to determine if maternal vitamin D insufficiency and/or deficiency during pregnancy is associated with the prevalence of preeclampsia and prematurity. DESIGN: A systematic review and meta-analysis of observational and interventional studies. METHODS: Two independent researchers reviewed the included studies according to PRISMA reporting guidelines. A protocol for this review was registered in PROSPERO with the registration number: "CRD42019136318". Three electronic databases (PubMed, ScienceDirect and Web of Science); were searched in order to identify eligible studies. Observational and interventional studies were selected which had been published in the last 6 years, and analysed the association between maternal vitamin D concentrations during pregnancy and the development of preeclampsia and/or preterm birth. Data were extracted and presented in tables and figures. Fixed and random-effects meta-analyses were performed on the studies which provided enough sample data to calculate odds ratios. Results from both statistical methods were compared. Meta-analysis cut-off points for vitamin D insufficiency and deficiency were defined as <75nmol/L and <50nmol/L, respectively. RESULTS: Fifty-five studies met the inclusion criteria. Fixed-effects meta-analysis of the interventional studies indicated that vitamin D supplementation acts as a prevention factor for preeclampsia and prematurity. Fixed-effects meta-analysis of observational studies concluded that vitamin D insufficiency and deficiency are associated with a higher risk of developing preeclampsia. However, prematurity and vitamin D were only associated when maternal vitamin D concentrations was <75 nmol/L. Random-effects meta-analysis found no significant association between vitamin D, preeclampsia and prematurity in either observational or interventional studies. CONCLUSION: Higher vitamin D concentrations during pregnancy could be associated with a decreased risk of preeclampsia and prematurity but statistical significance of associations depends on the study design used. Well-designed clinical trials with vitamin D supplementation are needed in order to better define associations.

Nine-month clinical outcomes in patients with diabetes treated with polymer-free sirolimus-eluting stents and 6­month vs. 12­month dual-antiplatelet therapy (DAPT).

BACKGROUND: Diabetes mellitus is known to be associated with worse clinical outcomes in patients with coronary artery disease (CAD) undergoing percutaneous coronary interventions (PCI) with drug-eluting stents (DES). Defining the optimal duration of dual antiplatelet therapy (DAPT) after DES implantation is still under debate. The objective of this subgroup analysis of the all-comers ISAR 2000 registry was to assess the safety and efficacy of a short DAPT (<6 month) versus a longer DAPT (>6 month) in patients with diabetes electively treated with the polymer-free sirolimus-coated ultrathin strut drug-eluting stent (PF-SES). METHODS: Patients who received the PF-SES were investigated in a multicenter all-comers observational study. The primary endpoint was the 9­month target lesion revascularization (TLR) rate, whereas secondary endpoints included the 9­month major adverse cardiac event (MACE) and procedural success rates. RESULTS: In all, 167 patients were treated with DAPT for ≤6 months (S-DAPT group) and 350 patients underwent DAPT treatment for 12 months (L-DAPT group). There was no significant difference in the overall MACE rate (4.6% vs. 3.1%, p = 0.441), the 9­month accumulated stent thrombosis rates (0.8% vs. 0.3%, p = 0.51), or the accumulated rate of bleeding complications (5.3% vs. 3.4%, p = 0.341). CONCLUSION: PF-SES are safe and effective in daily clinical routine with low rates of TLR and MACE in patients with diabetes and stable disease. Our data suggest that extending the duration of DAPT beyond 6 months does not improve MACE or TLR at 9 months in patients with stable CAD (ClinicalTrials.gov Identifier NCT02629575).

Comparison of the performance of the CRUSADE, ACUITY-HORIZONS, and ACTION bleeding risk scores in STEMI undergoing primary PCI: insights from a cohort of 1391 patients.

AIMS: To compare the performance of the CRUSADE, ACUITY-HORIZONS, and ACTION risk models in the ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI). METHODS: We studied all consecutive patients with STEMI who underwent PPCI at our institution between 2006 and 2010 (n=1391). The CRUSADE, ACUITY-HORIZONS, and ACTION risk scores were calculated based on the patients' clinical characteristics. The occurrence of in-hospital major bleeding (defined as the composite of intracranial or intraocular bleeding, access site haemorrhage requiring intervention, reduction in haemoglobin ≥4 g/dl without or ≥3g/dl with overt bleeding source, reoperation for bleeding, or blood transfusion) reached 9.8%. Calibration and discrimination of the three risk models were evaluated by the Hosmer-Lemeshow test and the C-statistic, respectively. We compared the predictive accuracy of the risk scores by the DeLong non-parametric test. RESULTS: Calibration of the three risk scores was adequate, given the non-significant results of Hosmer-Lemeshow test for the three risk models. Discrimination of CRUSADE, ACUITY-HORIZONS, and ACTION models was good (C-statistic 0.77, 0.70, and 0.78, respectively). The CRUSADE and ACTION risk scores had a greater predictive accuracy than the ACUITY-HORIZONS risk model (z=3.89, p-value=0.0001 and z=3.51, p-value=0.0004, respectively). There was no significant difference between the CRUSADE and ACTION models (z=0.63, p=0.531). CONCLUSIONS: The CRUSADE, ACUITY-HORIZONS, and ACTION scores are useful tools for the risk stratification of bleeding in STEMI treated by PPCI. Our findings favour the CRUSADE and ACTION risk models over the ACUITY-HORIZONS risk score.
