Background: Nonunion rates in hind or midfoot arthrodesis have been reported as high as 41%. The most notable and readily modifiable risk factor that has been identified is smoking. In 2018, 14.4% of the UK population were active smokers. We examined the effect of smoking status on union rates for a large cohort of patients undergoing hind- or midfoot arthrodesis. Methods: In total, 381 consecutive primary joint arthrodeses were identified from a single surgeon’s logbook (analysis performed on a per joint basis, with a triple fusion reported as 3 separate joints). Patients were divided based on self-reported smoking status. Primary outcome was clinical union. Delayed union, infection, and the need for ultrasound bone stimulation were secondary outcomes. Results: Smoking prevalence was 14.0%, and 32.2% were ex-smokers. Groups were comparable for sex, diabetes, and body mass index. Smokers were younger and had fewer comorbidities. Nonunion rates were higher in smokers (relative risk, 5.81; 95% CI, 2.54-13.29; P < .001) with no statistically significant difference between ex-smokers and nonsmokers. Smokers had higher rates of infection ( P = .05) and bone stimulator use ( P < .001). Among smokers, there was a trend toward slower union with heavier smoking ( P = .004). Conclusion: This large retrospective cohort study confirmed previous evidence that smoking has a considerable negative effect on union in arthrodesis. The 5.81 relative risk in a modifiable risk factor is extremely high. Arthrodesis surgery should be undertaken with extreme caution in smokers. Our study shows that after cessation of smoking, the risk returns to normal, but we were unable to quantify the time frame. Level of Evidence: Level III, retrospective cohort study.

Background: The association between tuberculosis (TB) and diabetes mellitus (DM) is re-emerging with the epidemic of type II diabetes. Both TB and DM were of the top 10 causes of death.[1] This study explores diabetes mellitus as a risk factor for developing the different antitubercular drug-resistant (DR) patterns among TB patients.  Methods: A retrospective cohort study has been conducted on all TB cases reported to the King Abdul Aziz University Hospital, Jeddah, between January 2012 to January 2021. All culture-confirmed and PCR-positive TB cases were included in this study. Categorical baseline characteristic of TB patient has been compared with DM status by using Fisher's exact and Pearson chi-square test. The univariable and multivariable logistic regression model was used to estimate the association between DM and different drug resistance patterns.  Results: Of the total 695 diagnosed TB patients, 92 (13.24%) are resistant to 1st line anti TB drugs. Among 92 DR-TB patients, 36 (39.13%) are diabetic. The percentage of different patterns of DR-TB with DM, in the case of mono DR (12.09%), poly DR (4.19%) MDR (0.547%). As a risk factor, DM has a significant association with DR-TB, mono drug-resistant, and pyrazinamide-resistant TB (P-value <0.05). The MDR and PDR separately do not show any significant association with DM, but for further analysis, it shows a significant association with DM when we combined.  Conclusion: Our study identified diabetes mellitus as a risk factor for developing DR-TB. Better management of DM and TB infection caring programs among DM patients might improve TB control and prevent DR-TB development in KSA.
