Association between underweight and overweight/obesity with oral health among independently living Brazilian elderly

ObjectivePoor oral status, represented by partial/complete tooth loss, may lead to changes in food choice, which may ultimately lead to underweight, overweight, or obesity. The aim of this study is to evaluate whether poor oral status is associated with underweight or overweight/obesity, regardless of physical activity.MethodsThis cross-sectional study is part of a major project, The Frailty in Brazilian Elderly Study, carried out in Campinas, Brazil (2008–2009). The sample was composed of 900 independent-living older adults. Complete data were available for 875 individuals including sociodemographic, self-reported amount of medications used and eating difficulty questionnaire, smoking habit, depressive symptoms, physical activity, oral examination, and anthropometric assessments according to the WHO criteria. Body mass index was used as an outcome. Multinomial logistic regression was adjusted for confounding variables.ResultsThe mean age of the sample was 72.7 y (±5.81) and the prevalence of edentulism was 47.7%. Edentate individuals not wearing dentures were more likely to be underweight [odds ratio (OR) = 3.94, 95% confidence interval (CI) 1.14–13.64] and overweight/obese (OR = 2.88, 95%CI 1.12–7.40). Males (OR = 0.56, 95%CI 0.36–0.85) and those not using medications (OR = 0.41 95%CI 0.24–0.70) were less likely to be overweight/obese. Individuals who smoke (OR = 2.62, 95%CI 1.26–5.44) were more likely to be underweight. Older individuals with family income between 3.1 and 5 minimum wage (OR = 1.69, 95%CI 1.00–2.87) were more likely to be overweight/obese.ConclusionTo our knowledge, this is one of the first studies associating poor oral health, represented by edentulism not rehabilitated with dentures, with unfavorable body mass, regardless of the two major confounders, physical activity and depression symptoms.     

Metalloproteinase Inhibition Protects against Reductions in Circulating Adrenomedullin during Lead‐induced Acute Hypertension

Intoxication with lead (Pb) results in increased blood pressure by mechanisms involving matrix metalloproteinases (MMPs). Recent findings have revealed that MMP type two (MMP‐2) seems to cleave vasoactive peptides. This study examined whether MMP‐2 and MMP‐9 levels/activities increase after acute intoxication with low lead concentrations and whether these changes were associated with increases in blood pressure and circulating endothelin‐1 or with reductions in circulating adrenomedullin and calcitonin gene‐related peptide (CGRP). Here, we expand previous findings and examine whether doxycycline (a MMPs inhibitor) affects these alterations. Wistar rats received intraperitoneally (i.p.) 1st dose 8 μg/100 g of lead (or sodium) acetate, a subsequent dose of 0.1 μg/100 g to cover daily loss and treatment with doxycycline (30 mg/kg/day) or water by gavage for 7 days. Similar whole‐blood lead levels (9 μg/dL) were found in lead‐exposed rats treated with either doxycycline or water. Lead‐induced increases in systolic blood pressure (from 143 ± 2 to 167 ± 3 mmHg) and gelatin zymography of plasma samples showed that lead increased MMP‐9 (but not MMP‐2) levels. Both lead‐induced increased MMP‐9 activity and hypertension were blunted by doxycycline. Doxycycline also prevented lead‐induced reductions in circulating adrenomedullin. No significant changes in plasma levels of endothelin‐1 or CGRP were found. Lead‐induced decreases in nitric oxide markers and antioxidant status were not prevented by doxycycline. In conclusion, acute lead exposure increases blood pressure and MMP‐9 activity, which were blunted by doxycycline. These findings suggest that MMP‐9 may contribute with lead‐induced hypertension by cleaving the vasodilatory peptide adrenomedullin, thereby inhibiting adrenomedullin‐dependent lowering of blood pressure.     

Is Robotic Revisional Bariatric Surgery Justified? An MBSAQIP Analysis

Background

The laparoscopic approach is utilized in greater than 90% of bariatric surgeries. With the growing prevalence of robotic-assisted surgery in bariatrics, there has been limited consensus on the superiority of either laparoscopic or robotic approaches, especially in revisional procedures (conversion from sleeve gastrectomy (SG) to Roux-en-Y gastric bypass (RYGB)).

Methods

A retrospective analysis was performed of the MBSAQIP PUF database of patients who underwent conversion from SG to RYGB procedures in either laparoscopic or robotic-assisted approaches. The groups underwent 2:1 propensity matching and primary outcomes included post-conversion days until discharge (POD), conversion operation length, total and major morbidity, 30-day readmission, 30-day reoperation, 30-day reintervention, and 30-day mortality after conversion.

Results

After 2:1 propensity score matching, 3411 patients (2274 laparoscopic vs 1137 robotic) were included in the study. Intraoperatively, no significant difference was found in total morbidity (6.5% lap vs 5.9% robotic) or major morbidity (1.9% lap vs 1.7% robotic); however, the operative times were significantly longer robotically (126 min vs 164 min). Post-operatively, no significant differences were found in discharge day (1.8 lap vs 1.8 robotic), 30-day readmission (7.6% lap vs 8.6% robotic), reoperation rate (2.9% lap vs 3.7% robotic), additional intervention rate (2.5% lap vs 3.3% robotic), or 30-day mortality (0.1% vs 0.1%).

Conclusion

There is no significant difference in perioperative or intraoperative outcomes between laparoscopic and robotic-assisted SG to RYGB conversion procedures other than a longer operative time in the robotic approach, suggesting increased efficiency with the laparoscopic approach.

Genetic imbalances detected by multiplex ligation-dependent probe amplification in a cohort of patients with oral squamous cell carcinoma—the first step towards clinical personalized medicine

Oral tumors are a growing health problem worldwide; thus, it is mandatory to establish genetic markers in order to improve diagnosis and early detection of tumors, control relapses and, ultimately, delineate individualized therapies. This study was the first to evaluate and discuss the clinical applicability of a multiplex ligation-dependent probe amplification (MLPA) probe panel directed to head and neck cancer. Thirty primary oral squamous cell tumors were analyzed using the P428 MLPA probe panel. We detected genetic imbalances in 26 patients and observed a consistent pattern of distribution of genetic alterations in terms of losses and gains for some chromosomes, particularly for chromosomes 3, 8, and 11. Regarding the latter, some specific genes were highlighted due to frequent losses of genetic material—RARB, FHIT, CSMD1, GATA4, and MTUS1—and others due to gains—MCCC1, MYC, WISP1, PTK2, CCND1, FGF4, FADD, and CTTN. We also verified that the gains of MYC and WISP1 genes seem to suggest higher propensity of tumors localized in the floor of the mouth. This study proved the value of this MLPA probe panel for a first-tier analysis of oral tumors. The probemix was developed to include target regions that have been already shown to be of diagnostic/prognostic relevance for oral tumors. Furthermore, this study emphasized several of those specific genetic targets, suggesting its importance to oral tumor development, to predict patients’ outcomes, and also to guide the development of novel molecular therapies.
