Endoscopic ultrasonography (EUS) is an essential diagnostic tool for various types of pancreatic diseases such as pancreatic tumors and chronic pancreatitis; however, EUS imaging has low specificity for the diagnosis of pancreatic diseases. Artificial intelligence (AI) is a mathematical prediction technique that automates learning and recognizes patterns in data. This review describes the details and principles of AI and deep learning algorithms. The term AI does not have any definite definition; almost all AI systems fall under narrow AI, which can handle single or limited tasks. Deep learning is based on neural networks, which is a machine learning technique that is widely used in the medical field. Deep learning involves three phases data collection and annotation, building the deep learning architecture, and training and ability validation. For medical image diagnosis, image classification, object detection, and semantic segmentation are performed. In EUS, AI is used for detecting anatomical features, differential pancreatic tumors, and cysts. For this, conventional machine learning architectures are used, and deep learning architecture has been used in only two reports. Although the diagnostic abilities in these reports were about 85-95%, these were exploratory research and very few reports have included substantial evidence. AI is increasingly being used for medical image diagnosis due to its high performance and will soon become an essential technique for medical diagnosis.A mathematical aspect of the anharmonic downward distortion following (ADDF) path is discussed. 2,6-Dihydroxypurine The ADDF method is utilized as an automated reaction path search method, which can explore transition state geometries on a potential energy surface from a potential minimum. We show that the maximum number of the ADD stationary paths intersecting the potential minimum is 2f + 1  - 2, where f denotes the degree of freedom of the system. We also show that the bifurcation of the ADD stationary path is essential to detect all the transition states connected from a given minimum. The ADDF computation is demonstrated for a H2 O molecule in which pitchfork bifurcation is observed.
Glycine powder air polishing (GPAP) procedure has become popular. Aim of the analysis was to compare the clinical outcomes during supportive periodontal therapy (SPT) of subgingival application of GPAP with those using sole conventional mechanical debridement (SC).

Over a median SPT period of 5.3years (re-evaluation through last observation), the GPAP cohort (n=263) received supra- and subgingival biofilm removal with GPAP. Supragingival calculus was removed using curets and sonic scalers here. Patients in the SC cohort (n=264) were treated with sonic scalers, curets and rubber cup polishing only. Changes in, that is pocket probing depth (PPD) and furcation involvement were assessed retrospectively. A bootstrapping equivalence testing method in line with the principle of the two one-sided tests (TOST) procedure was used to compare clinical outcomes.

The GPAP procedure was statistically equivalent to SC regarding the number of sites with stable PPDs (83.3%; IQR 68.8%, 91.0% vs. 84.0%; IQR 77.8%, 90.0%). However, in the GPAP cohort, a trend towards deterioration in furcation status (no equivalence) was noted.

In periodontal maintenance, the use of GPAP instead of mechanical plaque removal does not improve the clinical outcome. It seems to be contraindicated to treat furcation defects with GPAP only.

Our primary aim was to test the Interpersonal Theory of Suicide's synergy hypothesis (i.e., the interaction between perceived burdensomeness and thwarted belongingness) in the proximal prediction of suicide ideation, while accounting for quadratic effects.

We used MTurk to recruit participants (N=478) with a lifetime history of suicidal thoughts and behaviors; they completed two batteries of self-report questionnaires three days apart.

Contrary to the synergy hypothesis, only suicide ideation and the quadratic effect of perceived burdensomeness at Time 1 were significant predictors of suicide ideation at Time 2. The quadratic effect of perceived burdensomeness indicated a u-shaped function, whereby scores at or above the 80
percentile on perceived burdensomeness at Time 1 had increasingly strong, positive associations with suicide ideation at Time 2, while scores under the 80
percentile were not predictive of suicide ideation at Time 2. Also, thwarted belongingness and suicide ideation at Time 1 were significant predictors of perceived burdensomeness at Time 2.

These findings add to a growing literature that does not support the synergy hypothesis and suggests the importance of including nonlinear terms when examining the Interpersonal Theory of Suicide's constructs.

Predominant patterns of initial progressive disease (PD) after first-line systemic therapy have been shown to be a substantial basis for local ablative therapy (LAT) for all disease sites in patients with oligometastatic NSCLC, suggesting that these patterns could be helpful in defining synchronous oligometastatic NSCLC. Therefore, this retrospective study aimed to propose a threshold number of metastases for synchronous oligometastatic NSCLC, based on the pattern of initial PD after first-line systemic therapy. The cut-off threshold number of metastases compatible with synchronous oligometastatic NSCLC was determined using receiver operating characteristic (ROC) curve analyses of PD at the initially involved sites alone. ROC analysis of 175 patients revealed that the presence of 1-3 metastases before first-line treatment (sensitivity, 85.9%; specificity, 97.3%; area under the curve, 0.91) was compatible with oligometastatic NSCLC, therefore we divided patients into oligometastatic NSCLC and non-oligometastatic NSCLC groups. Multivariate logistic regression analyses revealed oligometastatic NSCLC to be the only independent predictor of PD at initially involved sites alone (odds ratio 165.7; P less then .001). The median survival times in patients with oligometastatic or non-oligometastatic NSCLC were 23.0 and 10.9 mo (hazard ratio, 0.51; P = .002), respectively. Based on these findings, we propose synchronous oligometastatic NSCLC as 1-3 metastases in accordance with patterns of initial progression. The result of our study might be contributory to provide a common definition of synchronous oligometastatic NSCLC.White matter undergoes rapid development in the neonatal period. Its structure during and after development is influenced by neuronal activity. Pathological neuronal activity, as in seizures, might alter white matter, which in turn may contribute to network dysfunction. Neonatal epilepsy presents an opportunity to investigate seizures and early white matter development. Our objective was to determine whether neonatal seizures in the absence of brain injury or congenital anomalies are associated with altered white matter microstructure. In this retrospective case-control study of term neonates, cases had confirmed or suspected genetic epilepsy and normal brain magnetic resonance imaging (MRI) and no other conditions independently impacting white matter. Controls were healthy neonates with normal MRI results. White matter microstructure was assessed via quantitative mean diffusivity (MD). In 22 cases, MD was significantly lower in the genu of the corpus callosum, compared to 22 controls, controlling for gestational age and postmenstrual age at MRI. This finding suggests convergent abnormal corpus callosum microstructure in neonatal epilepsies with diverse suspected genetic causes. Further study is needed to determine the specific nature, causes, and functional impact of seizure-associated abnormal white matter in neonates, a potential pathogenic mechanism.
Breast milk (BM) contains various protective components, such as immunoglobulins, lactoferrin, lysozyme, oligosaccharides and immune cell subsets. We evaluated the effectiveness of BM eye drops in infants with eye discharge in a randomised controlled study.

Subjects were breastfed infants aged ≤180days, with eye discharge. We randomly assigned patients to receive eye drops of BM or sodium azulene sulphonate hydrate 0.02% ophthalmic solution (OS). The patients received drop of BM or OS for 7days. Improvement score of eye discharge in the groups was compared using a non-inferiority test.

The number of patients improved eye discharge was 119/155 (76.8%) and 119/157 (75.8%) in BM and OS groups, respectively. There were no significant differences between groups. The improvement score in eye discharge was 1.76±0.91 in the BM group and 1.71±0.96 in the OS group. The BM group was considered non-inferior to the OS group.

This study demonstrated that BM is no less effective than OS in infants with eye discharge aged ≤6months. The results suggested that the use of breast milk as eye drops could be considered as a first-line treatment for infants aged ≤6months with eye discharge.

To examine whether group prenatal care (PNC) increased key services and educational topics women reported receiving, compared with individual PNC in Malawi and Tanzania.

Data come from a previously published randomized trial (n=218) and were collected using self-report surveys. Late pregnancy surveys asked whether women received all seven services and all 13 topics during PNC. Controlling for sociodemographics, country, and PNC attendance, multivariate logistic regression used forward selection to produce a final model showing predictors of receipt of all key services and topics.

In multivariate logistic regression, women in group PNC were 2.49 times more likely to receive all seven services than those in individual care (95% confidence interval [CI] 1.78-3.48) and 5.25 times more likely to have received all 13 topics (95% CI 2.62-10.52).

This study provides strong evidence that group PNC meets the clinical standard of care for providing basic clinical services and perinatal education for pregnant women in sub-Saharan Africa. The greater number of basic PNC services and educational topics may provide one explanatory mechanism for how group PNC achieves its impact on maternal and neonatal outcomes. ClinicalTrials.gov NCT03673709, NCT02999334.
