Comparison of psychometric properties of GOHAI, OHIP-14, and OHIP-EDENT as measures of oral health in complete edentulous patients aged 60 years and more.

OBJECTIVES: To compare the psychometric properties of three OHRQoL indicators (GOHAI, OHIP-14, and OHIP-EDENT) in a group of complete edentulous subjects and to explore the ability of these instruments to distinguish between individuals with different prosthetic and oral health status. METHODS: This was a cross-sectional study. Edentulous individuals aged 60 years and more were recruited between January 2019 and February 2020 in a medical and dental care centers. The Lebanese versions of GOHAI, OHIP-14, and OHIP-EDENT were used. External and internal consistencies were assessed using intraclass correlation coefficient (ICC) and Cronbach alpha, respectively. The concurrent validity was evaluated by testing the indicators against a proxy measure of a similar concept. To test their discriminative abilities, the ADD (GOHAI and OHIP) and SC (GOHAI and OHIP) scores were dichotomized according to the 25th and 75th percentile, respectively, and multivariate analyses were performed using sociodemographic, clinical, and subjective health parameters as explanatory variables. RESULTS: Two hundred and two edentulous subjects (age: 72.94 ± 7.378 years) were included. The proportion of subjects with no impact was lower for OHIP-EDENT (7.9%) compared to GOHAI (28.2%) and OHIP-14 (38.6%). Reproducibility was satisfactory for all OHRQoL tools since they were able to reproduce the results consistently in time (ICC > 0.80). The Cronbach alpha values were greater than 0.8 indicating acceptable internal consistency. The concurrent validity of the three tools was acceptable since subjects with lower OHRQoL score were less satisfied with their dentures and reported a higher need for self-rated therapy. Concerning the discriminant validity, OHIP-EDENT was more discriminant than OHIP-14 and GOHAI, since it was more able to identify patients with poor prosthetic issues or using instable denture. CONCLUSION: The OHIP-EDENT was more effective in identifying edentulous individuals with oral and prosthetic problems. Our results can help decide which dental instrument to use to assess the perception of oral health in edentulous individuals. More prospective studies are required to compare their evaluative properties.

Validation of the Arabic version of the SF-36, generic questionnaire of quality of life related to health among the elderly in Lebanon.

BACKGROUND: Measuring health status of elderly is essential for the prediction of their health care needs. Health research usually considers objective outcome measure; however there is a need to increase self-reported measures of health. AIMS: The aim of this study was to assess the psychometric properties of the SF36 among a group of Lebanese elderly. METHODS: It was a cross-sectional observational study. A systematic sample of elderly people aged 60 years and more was selected from dispensary, private and governmental hospitals in Lebanon. Data were collected using face-to-face interview. The first part of the questionnaire consisted of sociodemographic characteristics. The second part consisted of the Arabic version of the SF-36. The third part consisted of Activity of Daily Living (ADL) scale, presence of health problems and number of medication consumed per day. RESULTS: A total of 250 elderly people were included. The mean age was 70.69±7.70 years. Cronbach alphas for all SF-36 scales exceeded 0.798. The intra-Class correlation coefficient varied between 0.675 (item 2) and 0.980 (items 14, 16 and 18) indicating good reliability. The quality of life (QoL) of women was poorer than men (p<0.001). It was significantly lesser when the number of health problems (p<0.001) and medications (p<0.001) increased, and the ADL score (p<0.05) decreased. CONCLUSION: SF-36 is a valid and reliable instrument for measuring QoL among Lebanese elderly and could be used for monitoring the QoL of this population.

Assessment of nutritional status of older patients attending a tertiary hospital in Middle Eastern country.

BACKGROUND AND PURPOSE: In hospitals, poor nutritional status could be associated with a higher incidence of nosocomial infections, postoperative complications and mortality. Subsequently the costs of providing health care and social services will increase. Malnutrition has often been described as the skeleton in the hospital closet, as it is often ignored, undiagnosed and untreated. Our study aimed to describe the nutritional status of hospitalized patients aged 60 years or more and to evaluate the associated risk factors. MATERIALS AND METHODS: This was an observational cross-sectional study conducted at a major tertiary teaching hospital in Beirut city. During a 7 months period, patients aged 60 and over and admitted in the medical and surgical units of the hospital were invited to participate in the study. Data were collected by means of a questionnaire including sociodemographic and medical characteristics, the Arabic version of the Mini Nutritional Assessment (MNA), the Activity of Daily Living (ADL) scale, and the American Society of Anesthesiologists (ASA) score. RESULTS: 171 participants aged 73.15 ± 8.06 years were included in the study. 52% of them were at risk of malnutrition and 13.5% were malnourished. Prevalence of malnutrition was higher in medical compared to surgical departments (16.2% vs. 10.5%, p = 0.003). Moreover, malnutrition was significantly associated with low level of education, high age, prolonged hospital stay, high number of medical comorbidities, polymedication, high ASA score and low ADL score (p < 0.05). CONCLUSIONS: Malnutrition or risk of malnutrition are found in 2 out of 3 hospitalized patients aged 60 years or more, and is associated with several specific risk factors. Screening and management of malnutrition should be considered a priority in order to improve the overall medical status of older people, reduce hospital stay and improve outcome and quality of life.

Social inequalities in oral health in a group of older people in a Middle Eastern country: a cross-sectional survey.

BACKGROUND AND OBJECTIVE: The percentage of Lebanese older people has increased considerably. Given that Lebanese seniors are marginalized in the health policy-making process, we suggest a high social inequality in oral health that has not been studied so far. The purpose of our study was to describe and compare oral health status in a group of Lebanese older people according to their socioeconomic status (SES) MATERIALS AND METHODS: Participants were recruited from three different primary health care clinics in Beirut, Lebanon. Data were collected from an administered questionnaire that included sociodemographic variables, perception of oral health, and regular dental visits. Oral examination included the number of missing and decayed teeth, the prosthetic status, and the number of functional dental units (FUs). The SES of the participants was determined by educational level, previous or actual work, and neighborhood level. RESULTS: 264 participants aged 71.4 ± 6.27 years (64.7% female) were included in the study. Regular dental visit, dental status, FU, and oral health perception were significantly related to the participants' place of residence, educational level, and work. Moreover, the mean number of missing teeth (p = 0.048) and decayed teeth (p = 0.018) was significantly elevated in the low SES. CONCLUSION: There is a clear socioeconomic inequality in oral health among the Lebanese older people. Further researches should explore the potential contribution of psychosocial and behavioral factors in explaining these disparities.

Impact of implant-supported prostheses on nutritional status and oral health perception in edentulous patients.

BACKGROUND & AIMS: Improvement of nutritional status and perception of oral health are supposed to be different with complete conventional denture or implant-supported fixed or removable prostheses. Since no study has been conducted in Lebanon, the aim of our study was to assess the nutritional status and oral heath related quality of life (OHRQoL) in totally edentulous patients after treatment with complete denture or implant supported-prostheses. MATERIAL AND METHODS: This was an observational clinical prospective study. A convenient sample of Lebanese people aged 60 years or more was selected between September 2013 and July 2015 from the Departments of removable and fixed prosthesis at Saint-Joseph University of Beirut. The treatment options included complete denture, implant-supported complete denture and implant-supported fixed prostheses. Nutritional status and OHRQoL were assessed with the Mini-Nutritional Assessment Index (MNA) and the Geriatric Oral Health Assessment Index (GOHAI) respectively at Baseline (first visit before treatment), 2-3 weeks after treatment (t1), 3 months (t2) and 6 months (t3) after treatment. RESULTS: Fifty-one participants (mean age: 69.39 ± 7.164 years) were included. The results have shown an improvement over time in nutritional status and OHRQoL for all treatment groups. However, 2-3 weeks after treatment the number of participants at risk of malnutrition was higher with complete removable denture, intermediate with implant-supported complete denture and lower with implant-supported fixed prostheses (p-value = 0.049). Moreover, the mean GOHAI score was significantly lower over time with complete removable denture compared to implant-supported prostheses (p-value <0.05). CONCLUSION: Our study has shown an enhancement in the quality of life and the nutritional status for implant supported-prostheses compared to conventional removable dentures. Therefore, it is fundamental that dentists communicate with their patients about implant treatment to understand their expectations, to explain the outcomes and achieve the desired clinical result.

Flow acceleration time and ratio of acceleration time to ejection time for prosthetic aortic valve function.

OBJECTIVES: We sought to evaluate whether ejection dynamics, particularly acceleration time (AT) and the ratio of AT to ejection time (ET), can differentiate prosthetic aortic valve (PAV) stenosis from controls and prosthesis-patient mismatch (PPM). BACKGROUND: Diagnosing PAV stenosis, especially in mechanical valves, may be challenging and has significant clinical implications. METHODS: Doppler echocardiography was quantitated in 88 patients with PAV (44 mechanical and 44 bioprosthetic; age 63 ± 16 years; valve size range 18 to 25 mm) of whom 22 patients had documented PAV stenosis, 22 had PPM, and 44 served as controls. Quantitative Doppler parameters included ejection dynamics (AT, ET, and AT/ET) and conventional PAV parameters. RESULTS: Patients with PAV stenosis had significantly lower effective orifice area (EOA) values and higher gradients compared with controls and PPM. Flow ejection parameters (AT and AT/ET) were significantly longer in the stenotic valves compared with PPM and controls (respective values for AT: 120 ± 24 ms, 89 ± 16 ms, and 71 ± 15 ms; for AT/ET: 0.4, 0.32, and 0.3, p ≤ 0.001). Patients with PPM had gradients and ejection dynamics that were intermediate between normal and stenotic valves. Receiver-operator characteristic (ROC) curve analysis showed that AT and AT/ET discriminated PAV stenosis from PPM and controls (area under ROC curve = 0.92 and 0.88, respectively). Combining AT with the conventional Doppler velocity index gave the highest area under the curve of 0.98 but was not statistically different from that of AT alone (p = 0.12). A cutoff of AT = 100 ms had a sensitivity and specificity of 86% for identifying PAV stenosis; for an AT/ET = 0.37, the sensitivity and specificity were 96% and 82%, respectively. Analysis by valve type (mechanical and biological) revealed similar results; however, biological valves had slightly higher areas under the curve for all systolic time intervals. CONCLUSIONS: Ejection dynamics through PAV, particularly AT and AT/ET, are reliable angle-independent parameters that can help evaluate valve function and identify PAV stenosis.

Platypnea-orthodeoxia: an unusual case of hypoxemia.

A 52 year old female presented for two weeks of acute onset dyspnea on exertion. She was found to be hypoxic with a room air saturation of 88%. Baseline echocardiogram was normal with the exception of aortic root dilation. Right and left heart catheterizations were performed. The coronary arteries were normal in original and without disease. The right heart catheterization demonstrated normal pulmonary pressures and "no evidence of intra-cardiac shunt". Repeat echocardiogram was performed with agitated saline contrast and revealed a small amount of right to left shunting across the intra-atrial septum with cough while supine and significant right to left shunting while upright; these findings were consistent with the presence of a patent foramen ovale (PFO) and platypnea-orthodeoxia syndrome. The patient underwent percutaneous closure of her PFO with an Amplatzer device, and exhibited rapid resolution of her symptoms and hypoxia. She is off oxygen and has returned to work as a nurse practitioner. The case highlights the importance of clinical vigilance and consideration of this syndrome in the differential diagnosis of unexplained hypoxia. Our patient had a dramatic and positive outcome: complete alleviation of dyspnea and oxygen dependence after PFO closure.

Investigation of the association between angiographically defined coronary artery disease and periodontal disease.

BACKGROUND: The association between periodontal disease and coronary artery disease (CAD) has been investigated in numerous studies with inconsistent results. Resolving these differences is complicated by the use of varying definitions of CAD. The aim of this study was to investigate the association between angiographically-defined CAD and periodontal disease. METHODS: Non-smoking, non-diabetic patients, over 40 years of age, with no history of a myocardial infarction in the previous 6 months and who had undergone cardiac catheterization within the previous 12 months were enrolled in this study. Subjects were classified as having CAD (CAD+) if they had 50% stenosis in at least one major epicardial artery and classified as CAD negative (CAD-) if they had <50% stenosis in all identified arteries. Periodontal disease severity was measured through bleeding on probing, probing depth, clinical attachment level (CAL), gingival recession, number of missing teeth, and radiographic bone loss. RESULTS: One hundred (53 = CAD+; 47 = CAD-) patients were examined. CAD+ patients were more likely to be male (CAD+ 83.0% male; CAD- 40.4% male; P= 0.001), and were older (CAD+ 65.3 years; CAD- 60.8 years; P= 0.0138). Although all patients reported they were currently non-smokers and had not smoked for at least 5 years, the fraction who were former smokers was greater for CAD+ patients (66% versus 24.4%; P = 0.0001) and mean pack/year history of smoking was higher for CAD+ patients (15.8 versus 4.5; P = 0.0003). Mean CAL (3.13 mm versus 2.78 mm; P 0.0227), number of sites with CAL > or = 6 mm (6.85 versus 3.32; P = 0.0242), radiographic bone loss (3.60 mm versus 3.18 mm; P = 0.0142) were greater for CAD+ patients than for CAD- patients. However, after adjustment for age and previous smoking history, factors common to both diseases, the associations of CAD and periodontal disease were reduced and were not statistically significant (odds ratio [OR]: mean CAL OR = 1.06; number of sites with CAL > or = 6 mm OR = 1.03; mean radiographic bone loss OR = 1.31; P > or = 0.2055). CONCLUSIONS: After accounting for factors common to both periodontal disease and CAD, there was no significant association between periodontal disease and chronic CAD as assessed angiographically. Further investigations into the relationship between periodontal disease and CAD should clearly separate chronic CAD and acute coronary events.
