Periprocedural Changes of Serum Biomarkers in Predicting Complications Following Bariatric Surgery for Obesity: Systematic Review and Meta-analysis

Bariatric surgery is an effective treatment for severe obesity, but complications and peri-operative monitoring are important considerations. We conducted a comprehensive review of studies assessing pre-operative biomarkers and complications in patients undergoing bariatric surgery. A total of 14 studies were included. Gastric leak, infections, bleeding, obstruction or stenosis, hypoglycemia, and hypoalbuminemia were the most common complications observed. Our analysis showed a significant association between lower pre-operative albumin levels and complications (SMD [95%CI] =  - 0.21 [- 0.38; - 0.04]). However, other biomarkers did not have a significant impact on complication occurrence. Changes in C-reactive protein, neutrophil-lymphocyte ratio, and white blood cell levels were observed in certain peri-operative time points and complication subgroups. These findings suggest the potential use of pre-operative biomarkers and peri-operative changes of biomarker's levels for predicting complications.

Burden of ischemic heart disease in the Middle East and North Africa (MENA) and attributable risk factors: An epidemiological analysis from 1990 to 2019

Introduction

Despite the burden of ischemic heart disease (IHD), there remains a paucity of research on the incidence, mortality, and burden of this condition in the Middle East and North Africa (MENA) regions. This study aimed to evaluate the epidemiology and the risk factors associated with IHD in the MENA region.

Methods

This study was performed based on the GBD study 2019 data. We retrieved the data related to the epidemiology and burden of IHD, including prevalence, incidence, years of life lost due to premature death (YLLs), years lived with disability (YLDs), and mortality at the global level and in MENA countries across years and sexes.

Results

IHD accounted for approximately 2.55 million (95 % UI 2.29-2.83) incident cases in MENA in 2019, with an age-standardized incidence rate of 613.87 (95 % UI 555.84-675.16) per 100 000 people, which has decreased by 9 % between 1990 and 2019. IHD accounted for 11.01 % of DALYs causes in MENA in 2019, an increase of 68 % compared to 1990. The DALYs rate from IHD increased with age in both men and women and was higher in men than in women in all age groups, except 85-89 years age-group, in 2019.

Conclusion

The age-standardized prevalence and incidence of IHD are decreasing in MENA. However, this reduction is lower than the global level, which can be due to a weaker performance of the countries in the region in reducing the prevalence and incidence of the disease compared to the global average.

Uterine and Cervical Cancer in Iran: An epidemiologic analysis of the Iranian National Population-Based Cancer Registry

BACKGROUND

Gynecologic cancers, including neoplasms of the cervix and uterine, are the fourth most common malignancies, causing 3.46% of deaths in women aged 15 to 59.

OBJECTIVES

We aimed to report the Iranian National Population-based Cancer Registry (INPCR) results for Cervical and Uterine cancers in 2017.

METHODS

The total population of Iran in 2017 was 80881792. INPCR collected data on cervical and uterine cancer incidence from 31 provinces of Iran. In this project, we retrospectively examined all the country's regions in terms of screening for the existence of these two cancers. The registry data bank in Iran was used.

RESULTS

Overall, 3481 new cervical and uterine cancer cases were registered in INPCR, including 842 cases of cervical cancer (with a crude rate of 1.04) and 2639 cases of uterine cancer (with a crude rate of 3.26). The average age-standardized incidence rate (ASR) was 0.99 for cervical cancer and 3.29 for uterine cancer. Out of 3481 new cervical and uterine cancer cases, 2887 were registered with pathological findings and 594 without pathological confirmation. In cervical cancers, the highest rate was related to squamous cell carcinoma, with 486 cases (57.72%).

CONCLUSION

Our results showed that Iran is a low-risk area for the incidence of cervical and uterine cancers. In this study, the highest rate of cervical cancer was related to squamous cell carcinoma, confirming previous reports. However, this rate was lower than previous studies and suggested an increase in other types of cervical cancer in Iran.
