Background: Cervical cancer (CC) ranks fourth among cancers diagnosed around the world, but early detection and treatment can reduce invasive cervical cancer and mortality. Screening programs (CCSP), such as the one covering Thailand's 75 provinces, use histology to confirm cases. The study determined the incidence rate (IR) and investigated the factors associated with non-histologically proven invasive cancer of the uterine cervix (non-HPICUC) with an abnormal pap smear from the CCSP at Mahasarakham Hospital, Thailand.
Methods: The CCSP was used to analyse a retrospective cohort of 288 women between 30 and 60 years of age. All abnormal pap smears were followed up until April 30, 2022. We estimated the IR and assessed the relationship between various independent variables and non-HPICUC using the generalised linear model (GLM) for testing association data. We reported the adjusted RR and 95% confidence intervals (95%CI).
Results: 260 non-HPICUC cases had abnormal CCSP pap smears for an overall IR of 90.0 (95% CI: 86.3 - 93.2). After adjusting the model for all variables, age at recruitment and pregnancy had a statistically significant association with non-HPICUC (p-value < 0.05). We found that the risk of non-HPICUC increased 1.02 times for every 20-year increment in age compared to below that age (adjusted RR=1.02, 95% CI: 1.01 - 1.04). Pregnancy at risk for non-HPICUC was 0.89 times compared to non-pregnancy (adjusted RR=0.89, 95% CI: 0.80 - 0.99). Pathological vaginal discharge (PVD) did not have a statistically significant association with non-HPICUC (p-value = 0.094); notwithstanding, women with PVD had 1.08 times the risk of non-HPICUC compared to women without PVD (adjusted RR=1.08, 95% CI: 0.97 - 1.20).
Conclusions: Based on an abnormal pap smear from the CCS Program at Mahasarakham Hospital Thailand, age and pregnancy are associated with an increased risk of non-HPICUC. High-risk groups with abnormal pap smears should be targeted for CC campaigns.

The Pap smear is widely recognized in medicine as the single most successful contributor to cancer screening and preventative care. Women have Dr. George Papanicolaou (1870-1962) to thank for this groundbreaking contribution to their healthcare-a discovery that, fascinatingly, was made incidentally during his study of ovulation cycles in guinea pigs.

Purpose: The purpose of this study was to use the advanced technique of Network Intervention Analysis (NIA) to investigate the trajectory of symptom change associated with the effects of self-control training on youth university students' chronic ego depletion aftereffects.
Methods: The nine nodes of chronic ego depletion aftereffects and integrated self-control training were taken as nodes in the network and analyzed using NIA. Networks were computed at the baseline, at the end of treatment, at 1-, 3-, 6-, 9- and 12-month follow up.

Cervical cancer is one of the deadly diseases that affects women, which requires periodic examinations to identify and treat any cancerous tumors at a preliminary stage. The most prevalent examination tool for cervical cancer prompt identification is the cervical smear (Pap smear) testing; however, due to human negligence, this examination method has an elevated probability of negative findings. Cervical cancer classification using machine learning (ML) and deep learning (DL) has been extensively studied to enhance the conventional diagnostic process.
