RESUMO
BACKGROUND: Injections using buffered lidocaine may decrease discomfort, have a quicker onset, and be a more efficacious local anesthetic. Previous studies have been inconclusive in the oral context. PURPOSE: To address if bicarbonate buffered 2% lidocaine can decrease pain from the use of local anesthesia, has a quicker onset time, and is more efficacious. STUDY DESIGN: The design was a single-center double-blinded randomized control trial, set in an outpatient oral and maxillofacial clinic housed in the University of Cincinnati Medical Center. Inclusion criteria for the study were patients requiring a single tooth extraction due either to caries or periodontal disease. PREDICTOR VARIABLE: The predictor variable was the local anesthetic used either nonbuffered 2% lidocaine with 1:100,000 epinephrine (control) or bicarbonate buffered 2% lidocaine with 1:100,000 epinephrine (study) was randomly assigned. MAIN OUTCOME VARIABLES: Primary outcome variables were injection pain score, and postoperative pain, time to anesthetic onset, and the number of rounds of injections required to achieve adequate anesthesia. COVARIATES: The covariates were jaw involved, age, sex, and race, American Society of Anesthesiologists score, body mass index, current tobacco use, history of psychiatric illness, chronic pain, and preoperative pain score. ANALYSES: Test statistics were calculated using Wilcoxon rank-sum test, Kruskal-Wallis test, Spearman rank correlation test, χ2 test for bivariate analyses, and Fisher's exact test. P values ≤ .05 were considered statistically significant. RESULTS: The final sample was 114 subjects. The mean age of the sample was 42.97 years, standard deviation ±13.43 years. The sample was 39.47% male. The racial demographics were Caucasian (62.28%) and African American (33.33%). Buffered lidocaine did not have a statistically significant relationship with any of the outcomes. The jaw involved had a statistically significant association to the injection pain score (P value = .006), and the number of rounds of anesthetic required (P value = .047). Age showed a statistically significant association to injection pain score (P value = .032), and the number of rounds of anesthetic required (P value = .027). Finally, preoperative pain had a statistically significant relationship with injection pain score (P value = < .001). CONCLUSION AND RELEVANCE: In this study, bicarbonate buffered lidocaine did not exhibit any discernible advantages over nonbuffered lidocaine for any study outcomes.

STUDY OBJECTIVES: Obstructive sleep apnea (OSA) adversely affects normal blood pressure (BP) and may disrupt circadian BP patterns. We sought to examine 24-hour circadian BP rhythms in children with OSA and healthy controls. METHODS: Children 5-14 years with OSA and healthy controls underwent 24-hour BP monitoring and actigraphy to quantify sleep. Shape invariant statistical models compared circadian BP patterns (e.g. times of BP peaks, time arrived at peak BP velocity [TAPV]) in the OSA and control groups. RESULTS: The analytic sample included 219 children (mild OSA: nâ =â 52; moderate-to-severe OSA (MS-OSA): nâ =â 50; controls: nâ =â 117). In the morning, the MS-OSA group had earlier TAPV for DBP than controls (51 minutes, pâ <â 0.001). TAPV in the evening was earlier for the MS-OSA group than controls (SBP: 95 minutes, pâ <â 0.001; DBP: 28 minutes, pâ =â 0.028). At mid-day, SBP and DBP velocity nadirs were earlier for the MS-OSA group than controls (SBP: 57 minutes, pâ <â 0.001; DBP: 38 minutes, pâ <â 0.01). The MS-OSA group reached most BP values significantly earlier than controls; the largest differences were 118 minutes (SBP) and 43 minutes (DBP) (pâ <â 0.001). SBP and DBP were elevated in the MS-OSA group (hours 18-21 and 7--12, respectively, pâ <â 0.01) compared to controls. The MS-OSA group was prone to "non-dipping" compared to controls (SBP: odds ratio [OR]â =â 2.16, 95% CI: 1.09, 4.29; DBP: ORâ =â 3.45, 95% CI: 1.21, 10.23). CONCLUSIONS: Children with MS-OSA had changes in circadian BP patterns, namely earlier TAPV and BP peaks and nadirs than controls. Circadian disturbances in BP rhythms may be key to mapping the natural history of BP dysregulation in children with OSA.

Background and Aims: Non-communicable diseases such as hypertension and diabetes are matters of huge concern worldwide, with an increasing trend in prevalence over the previous decade. First of all, this study aimed to evaluate the association between economic status (ES) and body mass index (BMI), ES and comorbidity of hypertension and diabetes, and BMI and comorbidity independently. Second, it explored the mediating role of BMI in the association between ES and comorbidity of hypertension and diabetes. Finally, it investigated whether the mediating effect differs with the place of residence, gender, and education levels. Methods: A total of 11,291 complete cases from the Bangladesh demographic and health survey 2017-18 were utilized for this study. Survey-based binary logistic regression or multiple logistic regression was used to find the association among outcome, exposure, and mediator variables, and a counterfactual framework-based weighting approach was utilized for mediation analysis. Results: Middle-income (adjusted odds ratio [AOR]: 1.696, 95% confidence interval [CI]: 1.219, 2.360) and rich (AOR: 2.770, CI: 2.054, 3.736) respondents were more likely to have comorbidity of hypertension and diabetes compared to the poor. The odds of comorbidity increased with the increase in BMI. A positive association was observed between ES and BMI. A significant mediating role of BMI in the association between ES and comorbidity was found. We observed that 19.85% (95% CI: 11.50%, 49.6%) and 20.35% (95% CI: 14.9%, 29.3%) of total effect was mediated by BMI for middle and rich respondents, respectively, compared to the poor. Conclusions: The mediating role of BMI was greater for female, no or primary educated respondents, and respondents from rural areas. Therefore, the study will facilitate policymakers of Bangladesh and other countries with a similar set-up to decide on health policies regarding hypertension and diabetes.
RESUMO
OBJECTIVES: This study aimed to explore the effects of short birth spacing (SBS), which is defined as a period of less than 33 months between two successive births, on multiple concurrent forms of child malnutrition (MCFCM) and at least one form of child malnutrition (ALOFCM) using propensity score matching (PSM). METHODS: This study used data extracted from the 2017-18 Bangladesh Demographic and Health Survey. PSM with four different distance functions, including logistic regression, classification and regression tree, single hidden layer neural network and random forest, were performed to evaluate the effects of SBS on MCFCM and ALOFCM. We also explored how the effects were modified in different subsamples, including women's empowerment, education and economic status (women's 3E index)-constructed based on women's decision-making autonomy, education level, and wealth index, and age at marriage, and place of residence. RESULTS: The prevalence of SBS was 22.16% among the 4652 complete cases. The matched samples of size 2062 generated by PSM showed higher odds of MCFCM (adjusted OR (AOR)=1.25, 95% CI=1.02 to 1.56, p=0.038) and ALOFCM (AOR=1.20, 95% CI=1.01 to 1.42, p=0.045) for the SBS children compared with their counterparts. In the subsample of women with 3E index≥50% coverage, the SBS children showed higher odds of MCFCM (AOR: 1.43, 95% CI=1.03 to 2.00, p=0.041] and ALOFCM (AOR: 1.33, 95% CI=1.02 to 1.74, p=0.036). Higher odds of MCFCM (AOR=1.27, 95% CI=1.02 to 1.58, p=0.036) and ALOFCM (AOR=1.23, 95% CI=1.02 to 1.51, p=0.032) for SBS children than normal children were also evident for the subsample of mothers married at age≤18 years. CONCLUSION: SBS was significantly associated with child malnutrition, and the effect was modified by factors such as women's autonomy and age at marriage.

AIMS: To identify substance use disorder (SUD) patterns and their association with T2DM health outcomes among patients with type 2 diabetes and hypertension. METHODS: We used latent class analysis on electronic health records from the MetroHealth System (Cleveland, Ohio) to obtain the target SUD groups: i) only tobacco (TUD), ii) tobacco and alcohol (TAUD), and iii) tobacco, alcohol, and at least one more substance (PSUD). A matching program with Mahalanobis distance within propensity score calipers created the matched control groups: no SUD (NSUD) for TUD and TUD for the other two SUD groups. The numbers of participants for the target-control groups were 8009 (TUD), 1672 (TAUD), and 642 (PSUD). RESULTS: TUD was significantly associated with T2DM complications. Compared to TUD, the TAUD group showed a significantly higher likelihood for all-cause mortality (adjusted odds ratio (aOR) = 1.46) but not for any of the T2DM complications. Compared to TUD, the PSUD group experienced a significantly higher risk for cerebrovascular accident (CVA) (aOR = 2.19), diabetic neuropathy (aOR = 1.76), myocardial infarction (MI) (aOR = 1.76), and all-cause mortality (aOR = 1.66). CONCLUSIONS: The findings of increased risk associated with PSUDs may provide insights for better management of patients with T2DM and hypertension co-occurrence.

The purposes of the study include (i) demonstrating the US national level historical trends of the number of admitted patients due to substance abuse and those reported the selected substances at the time of admission, and more importantly, (ii) identifying the significant covariates in the association of using each of the substances along with the dynamics of likelihood over the different levels of the covariates. The trend of total admitted patients shows an increasing pattern from 1992 to 2008 and later exhibits a decreasing pattern before experiencing a significant upturn again in the last two consecutive years. During the study period, the highest growth rate of around 1088% is evident for methamphetamine followed by heroin (192%) and marijuana or hashish (45%), while both cocaine or crack (-33%) and alcohol (-29%) show negative growth rates. The estimated logistic regression models show that every covariate, including age, education, employment, gender, living status, race, and ethnicity, has a significant effect on the status of using each of the five selected substances. In parallel, the dynamics of likelihood over the levels of each covariate on every substance unearth even more information. In conclusion, the findings on trend analysis suggest the immediate attention to the growth in admissions for substance abuse treatment, and in response to taking appropriate policy measures, the likelihood dynamics revealed for every substance would undoubtedly play a vital role in identifying the target group as per priority.
