Inactivating alterations in the SWItch/Sucrose NonFermentable (SWI/SNF) Chromatin Remodeling Complex subunits have been described in multiple tumor types. Recent studies focused on SMARC subunits of this complex to understand their relationship with tumor characteristics and therapeutic opportunities. To date, pancreatic cancer with these alterations has not been well studied, although isolated cases of undifferentiated carcinomas have been reported. Herein, we screened 59 pancreatic undifferentiated carcinomas for alterations in SWI/SNF complex-related (SMARCB1 [BAF47/INI1], SMARCA4 [BRG1], SMARCA2 [BRM]) proteins and/or genes using immunohistochemistry and/or next-generation sequencing. Cases with alterations in SWI/SNF complex-related proteins/genes were compared with cases without alterations, as well as with 96 conventional pancreatic ductal adenocarcinomas (PDAC). In all tumor groups, mismatch repair and PD-L1 protein expression were also evaluated. Thirty of 59 (51%) undifferentiated carcinomas had a loss of SWI/SNF complex-related protein expression or gene alteration. Twenty-seven of 30 (90%) SWI-/SNF-deficient undifferentiated carcinomas had rhabdoid morphology (vs 9/29 [31%] SWI-/SNF-retained undifferentiated carcinomas; P < .001) and all expressed cytokeratin, at least focally. Immunohistochemically, SMARCB1 protein expression was absent in 16/30 (53%) cases, SMARCA2 in 4/30 (13%), and SMARCA4 in 4/30 (13%); both SMARCB1 and SMARCA2 protein expressions were absent in 1/30 (3%). Five of 8 (62.5%) SWI-/SNF-deficient undifferentiated carcinomas that displayed loss of SMARCB1 protein expression by immunohistochemistry were found to have corresponding SMARCB1 deletions by next-generation sequencing. Analysis of canonical driver mutations for PDAC in these cases showed KRAS (2/5) and TP53 (2/5) abnormalities. Median combined positive score for PD-L1 (E1L3N) was significantly higher in the undifferentiated carcinomas with/without SWI/SNF deficiency compared with the conventional PDACs (P < .001). SWI-/SNF-deficient undifferentiated carcinomas were larger (P < .001) and occurred in younger patients (P < .001). Patients with SWI-/SNF-deficient undifferentiated carcinoma had worse overall survival compared with patients with SWI-/SNF-retained undifferentiated carcinoma (P = .004) and PDAC (P < .001). Our findings demonstrate that SWI-/SNF-deficient pancreatic undifferentiated carcinomas are frequently characterized by rhabdoid morphology, exhibit highly aggressive behavior, and have a negative prognostic impact. The ones with SMARCB1 deletions appear to be frequently KRAS wild type. Innovative developmental therapeutic strategies targeting this genomic basis of the SWI/SNF complex and the therapeutic implications of EZH2 inhibition (NCT03213665), SMARCA2 degrader (NCT05639751), or immunotherapy are currently under investigation., (Copyright © 2024 United States & Canadian Academy of Pathology.

Background: The information on the clinicopathologic/outcome differences between ampullary adenocarcinoma (AC) and pancreatic adenocarcinoma (PC) has been conflicting to the extent that it still is questioned whether ACs need to be recognized separately from PCs., Methods: The characteristics of 413 ACs were compared with those of 547 PCs., Results: The ACs had a better prognosis than the PCs (5-year survival, 57 % vs 23 %; p < 0.001). Even the pancreatobiliary (PB)-type ACs had a better prognosis (5-year survival, 46 % vs 23 %; p < 0.001). Several differences also were identified as contributing factors: (1) the preinvasive adenomatous component often constituted a significant proportion of the mass in ACs (>50 % of the tumor in 16 % vs 1.5 %; p < 0.001); (2) the mean size of the carcinoma was smaller in ACs (2.5 vs 3.2 cm; p < 0.001): when matched for invasion size, the survival advantage of AC was minimized, and when matched for invasion size larger than 2 cm, the survival advantage of AC lost its statistical significance; (3) lymph node (LN) metastases were less common in ACs (49 % vs 71 %; p < 0.001); (4) the definitive R1 rate was lower in ACs (4 % vs 23.5 %; p < 0.001); and (5) non-PB and non-tubular adenocarcinoma types were more common in ACs (17 % vs 3 %; p < 0.001)., Conclusions: Comparatively, ACs have better clinical survival than PCs. Potential contributing factors are the relative abundance of the preinvasive component, smaller invasion, lower LN metastasis rate, higher resectability, and common occurrence of less aggressive histologic phenotypes (intestinal, medullary, mucinous). However, this survival advantage is sustained even in PB-type ACs, highlighting the importance of accurately determining the site of origin., (© 2024. Society of Surgical Oncology.)

Background: It is important to provide the necessary sleep for the growth of preterm infants in the neonatal intensive care unit. The purpose of this study was to determine the effect of 3-stair positioning pillows (TSPPs) developed for preterm infants with postnatal age 28 to 35 weeks on physiologic parameters and sleep-wakefulness status., Methods: This research was conducted as a randomized controlled experimental study. The CONSORT flowchart was used in the implementation of the randomized controlled trial. The preterm infants in the experimental group were placed in the prone position with TSPPs, whereas the preterm infants in the control group were followed in the routine prone position given in the neonatal intensive care unit. Preterm infants were followed for a total of 3 hours., Results: The sample of the study consisted of 60 preterm infants (experiment group = 30; control group = 30) who were hospitalized in the neonatal intensive care unit and met the selection criteria. Compared with the infants in the control group, the preterm infants in the experimental group were determined to have significantly lower heart rates, higher oxygen saturations, lower respiratory rates, longer sleep durations, and shorter wakefulness times (P < .001)., Conclusion: It was found that positioning preterm infants using TSPP had positive effects on physiological parameters (heart rate, oxygen saturation, and respiratory rate) and sleep-wakefulness status in favor of the experimental group., Implications for Practice: It is recommended to use a TSPP that supports the prone position to improve the physiologic parameters and sleep-wakefulness status of preterm infants in the neonatal intensive care unit. Larger studies need to be conducted utilizing longer follow-up protocols. Examining the effectiveness of TSPPs with different positioning materials in preterm infants is needed., Competing Interests: The authors declare no conflict of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

Background: Grade 1/2 PanNETs are mostly managed similarly, typically without any adjunct treatment with the belief that their overall metastasis rate is low. In oncology literature, Ki67-index of 10% is increasingly being used as the cutoff in stratifying patients to different protocols, although there are no systematic pathology-based studies supporting this approach., Methods: Ki67-index was correlated with clinicopathologic parameters in 190 resected PanNETs. A validation cohort (n = 145) was separately analyzed., Results: In initial cohort, maximally selected rank statistics method revealed 12% to be the discriminatory cutoff (close to 10% rule of thumb). G2b cases had liver/distant metastasis rate of almost threefold higher than that of G2a and showed significantly higher frequency of all histopathologic signs of aggressiveness (tumor size, perineural/vascular invasion, infiltrative growth pattern, lymph node metastasis). In validation cohort, these figures were as striking. When all cases were analyzed together, compared with G1, the G2b category had nine times higher liver/distant metastasis rate (6.1 vs. 58.5%; p < 0.001) and three times higher lymph node metastasis rate (20.5 vs. 65.1%; p < 0.001)., Conclusions: G2b PanNETs act very similar to G3, supporting management protocols that regard them as potential therapy candidates. Concerning local management, metastatic behavior in G2b cases indicate they may not be as amenable for conservative approaches, such as watchful waiting or enucleation. This substaging should be considered into diagnostic guidelines, and clinical trials need to be devised to determine the more appropriate management protocols for G2b (10% to ≤ 20%) group, which shows liver/distant metastasis in more than half of the cases, which at minimum warrants closer follow-up., (© 2024.

Objective: Osteoporosis, defined as a systemic skeletal disease, is characterized by increased bone fragility and fracture risk. Studies have shown that dysregulation of the functions of miRNAs or the mechanisms they mediate may be an important pathological factor in bone degeneration. Therefore, the aim of the study was to determine the role of miRNAs, which are thought to play a role in bone metabolism, in osteoporosis., Methods: The study included 48 patients who were diagnosed with osteoporosis according to the results of a bone mineral density assessment by quantitative computed tomography and 36 healthy individuals. MiRNAs from plasma samples obtained from blood samples taken into ethylenediaminetetraacetic acid (EDTA) tubes were isolated with the miRNA isolation kit and converted to cDNA. Expression analysis of miR-21-5p, miR-34a-5p, miR-210, miR-122-5p, miR-125b-5p, miR-133a, miR-143-3p, miR-146a, miR-155-5p, and miR-223 was performed on the real-time PCR (RT-PCR) device., Results: When miRNA expression levels in the patient group were compared with the control group, all miRNAs were found to be downregulated in the patients. When fold changes in expression levels in the patient group were examined, significant differences were found in miR-21-5p, miR-133a, mir143-3p, miR-210, and miR-223. In the receiver operating curve analysis, area under the curve=0.882 for the combination of miR-34, miR-125, miR-133, and miR-210., Conclusion: In this study, it was determined that the combined effects of miRNAs, as well as their single effects, were effective in the development of osteoporosis. Therefore, a miRNA panel to be created can make a significant contribution to the development of novel diagnostic and treatment approaches for this disease.

The aim of this study is to present the outcomes of cerebral aneurysm treatment with the DERIVO ® mini Embolisation Device (DMD), which is compatible with microcatheters with 0.021-inch inner diameters. Consecutive patients treated with DMD were identified retrospectively. Patient and aneurysm characteristics, procedural findings, clinical outcomes and follow-up imaging results were evaluated. A total of 44 target aneurysms in 30 patients were treated with DMD. The mean age of the patients was 49.9 (range, 4-77 years). Four patients with five aneurysms presented with acute subarachnoid hemorrhage. The mean aneurysm size was 6.8 mm (range, 1.5-22 mm). In 29 (65.9%) aneurysms, adjunctive devices were used for endovascular treatment. The overall mortality rate was 3.3% and procedure-related mortality was 0%. Overall neurologic morbidity was 6.6% and none of the patients had a permanent sequela secondary to the procedure. The mean clinical follow-up period was 20.9 months (range, 3 days-46 months) and the mean DSA follow-up period was 10.9 months. A total of 37 (84.1%) aneurysms demonstrated total occlusion (Raymond-Roy [RR 1]); 3 (6.8%) aneurysms had a neck remnant or infundibular filling at the origin of the jailed side branch (RR 2), 4 (9.1%) aneurysms had residual aneurysm filling (RR 3). For those aneurysms treated with bare DMD, the total occlusion rate was 73.3% at a mean follow-up of 16.1 months. In this initial clinical single-center experience, DMD had a good safety profile and efficacy comparable with the currently used flow diverters.

The guidelines recently recognized the intra-ampullary papillary tubular neoplasm (IAPN) as a distinct tumor entity. However, the data on IAPN and its distinction from other ampullary tumors remain limited. A detailed clinicopathologic analysis of 72 previously unpublished IAPNs was performed. The patients were: male/female=1.8; mean age=67 years (range: 42 to 86 y); mean size=2.3 cm. Gross-microscopic correlation was crucial. From the duodenal perspective, the ampulla was typically raised symmetrically, with a patulous orifice, and was otherwise covered by stretched normal duodenal mucosa. However, in 6 cases, the protrusion of the intra-ampullary tumor to the duodenal surface gave the impression of an "ampullary-duodenal tumor," with the accurate diagnosis of IAPN established only by microscopic correlation illustrating the abrupt ending of the lesion at the edge of the ampulla. Microscopically, the preinvasive component often revealed mixed phenotypes (44.4% predominantly nonintestinal). The invasion was common (94%), typically small (mean=1.2 cm), primarily pancreatobiliary-type (75%), and showed aggressive features (lymphovascular invasion in 66%, perineural invasion in 41%, high budding in 30%). In 6 cases, the preinvasive component was pure intestinal, but the invasive component was pancreatobiliary. LN metastasis was identified in 42% (32% in those with ≤1 cm invasion). The prognosis was significantly better than ampullary-ductal carcinomas (median: 69 vs. 41 months; 3-year: 68% vs. 55%; and 5-year: 51% vs. 35%, P =0.047). In conclusion, unlike ampullary-duodenal carcinomas, IAPNs are often (44.4%) predominantly nonintestinal and commonly (94%) invasive, displaying aggressive features and LN metastasis even when minimally invasive, all of which render them less amenable to ampullectomy. However, their prognosis is still better than that of the "ampullary-ductal" carcinomas, with which IAPNs are currently grouped in CAP protocols (while IAPNs are kindreds of intraductal tumors of the pancreatobiliary tract, the latter represents the ampullary counterpart of pancreatic adenocarcinoma/cholangiocarcinoma)., Competing Interests: Conflicts of Interest and Source of Funding: O.B. has been supported in part by the Cancer Center Support Grant of the National Institutes of Health/National Cancer Institute under award number P30CA008748.

The A disintegrin and metalloprotease (ADAM) family is involved in many vital cellular events, from proliferation to migration, and accumulated evidence suggests its increased expression in malignant tumors. In this study, we investigated ADAM17 expression in non-small cell lung cancer (NSCLC) and its relationship with clinicopathological factors and survival. Immunohistochemical staining of ADAM expression was performed in 108 patients with NSCLC and in 54 control cases with no known malignant diagnosis. Association between ADAM17 expression, clinicopathological factors, and survival were analyzed. The Kaplan-Meier method was used for survival analysis. ADAM17 was lowly expressed in 89 (82.4%) and highly expressed in 19 (17.6%) of the patients with NSCLC. In univariate analysis, high ADAM17 expression, lymphovascular invasion, stage, and treatment response significantly affected progression-free survival (PFS) and overall survival (OS) (p < 0.05). Multivariate analysis also showed that high ADAM17 expression, lymphovascular invasion, stage, and treatment response were important prognostic factors for PFS and OS (p < 0.05). Our study revealed that high ADAM17 expression significantly associated with OS and PFS in patients with NSCLC. ADAM17 may potentially be the area of a new targeted treatment strategy in NSCLC. Thus, routine evaluation of ADAM17 expression in patients with NSCLC may be a future consideration., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

A fusion between tubulin polymerization-promoting protein (TPPP), a regulatory cytoskeletal gene, and the chromatin remodeling factor, bromodomain-containing protein 9 (BRD9), TPPP-BRD9 fusion has been found in rare cancer cases, including lung and gallbladder cancers (GBC). In this study, we investigated the histopathological features of 16 GBCs previously shown by RNA sequencing to harbor the TPPP-BRD9 fusion. Findings in the fusion-positive GBCs were compared with 645 GBC cases from the authors' database. Among the 16 TPPP-BRD9 fusion-positive GBC cases, most were females (F:M = 7:1) of Chinese ethnicity (12/16), whereas the remaining cases were from Chile. The histopathological examination showed the following findings: 1) Intracholecystic neoplasm (ICN) in 7/15 (47% vs. 7% 645 reference GBCs, p < 0.001), all with gastro-pancreatobiliary phenotype, often with clear cell change, and in the background of pyloric gland metaplasia and extensive high-grade dysplasia. 2) Neuroendocrine carcinoma (NEC) morphology: 3 cases (27% vs. 4.6% in the reference database, p = 0.001) showed a sheet-like and nested/trabecular growth pattern of monotonous cells with salt-and-pepper chromatin characteristic of NECs. Two were large cell type, one had prominent clear cell features, a rare finding in GBNECs; the other one had relatively bland, well-differentiated morphology, and the remaining case was small cell type. 3) Adenocarcinoma identified in 8 cases had a distinctive pattern characterized by widely separated small, round tubular units with relatively uniform nuclei in a fashion seen in mesonephric adenocarcinomas, including hobnail-like arrangement and apical snouts, reminiscent of tubular carcinomas of the breast in many areas. In some foci, the epithelium was attenuated, and glands were elongated, some with comma shapes, which along with the mucinous/necrotic intraluminal debris created a "syringoid" appearance. 4) Other occasional patterns included the cribriform, glomeruloid patterns, and metaplastic tubular-spindle cell pattern accompanied by hemorrhage. In conclusion, TPPP-BRD9 fusion-positive GBCs often develop through intracholecystic neoplasms (adenoma-carcinoma sequence) of gastro-pancreatobiliary lineage, appear more prone to form NEC morphology and have a propensity to display clear cell change. Invasive adenocarcinomas arising in this setting often seem to display a distinctive appearance that we tentatively propose as the TPPP-BRD9 fusion-positive pattern of GBC., Competing Interests: Declaration of competing interest The authors have no conflict of interest to declare., (Copyright © 2024.

Objective: Task-oriented therapy (TOT) is used to increase the effectiveness of upper extremity (UE) in activity daily living (ADL). This study aimed to investigate the effect of TOT on the participation and ADLs of stroke patients., Methods: Between October 2018 and February 2019, 28 chronic stroke patients were included in the study treated in Kocaeli University Hospital, Department of Physical Medicine and Rehabilitation, Turkey. The performance areas and participation status of the patients in which they experienced limitations were evaluated with the Canadian Occupational Performance Scale (COPM), and their level of independence in ADLs was evaluated with the Modified Frenchay Activity Index (mFAI) and Barthel Index (BI). All patients were included in the occupational therapy (OT) program five days a week for three weeks at Kocaeli University Hospital. Three ADLs in which they had difficulties were studied with 28 patients. Each of the activities was designed specifically for the patient. All assessments were repeated after three weeks of treatment., Results: A total of 28 patients, 12 females and 16 males, diagnosed with stroke, were included in the study. A statistically significant increase was found in the COPM performance and satisfaction value compared to the pre-treatment value (p<0.001). A statistically significant difference was found between pre- and post-treatment mFAI and BI values (p<0.001)., Conclusions: Adding task-oriented therapy to the rehabilitation programs of stroke patients will contribute to the improvement of ADL., Competing Interests: Competing interests: None., (Copyright: © Pakistan Journal of Medical Sciences.)

Objective: To investigate the effects of tub bathing on the skin and bilirubin levels of newborns receiving tunnel and light-emitting diode phototherapy., Methods: In this randomized controlled trial, hospitalized newborns diagnosed with hyperbilirubinemia treated with a tunnel or light-emitting diode device were randomly assigned to either the experimental (bath) or control (no bath) groups using a computer program. The skin integrity moisture balance of all groups was recorded using the Newborn Skin Condition Score at 6, 12, and 24 hours after phototherapy, and their total serum bilirubin measurements were evaluated., Results: A statistically significant difference was observed in the babies' total serum bilirubin levels; this decrease was the highest in the experimental groups. Further, the skin integrity-moisture balance was higher in the experimental groups than in the control groups; it was highest in the tunnel-experimental group and lowest in the tunnel control group., Conclusions: These results show that bathing is effective in reducing total bilirubin levels. This study adds to the evidence on skin integrity and moisture balance in newborns who were bathed during phototherapy., (Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.)

A 50-year-old male patient with a history of transcranial surgery and subsequent radiotherapy for a pituitary adenoma presented with repetitive pulsatile nasal bleeding. A right cavernous segment pseudoaneurysm was discovered on the angiogram, and the patient failed the balloon occlusion test. A Papyrus (Biotronik, Berlin, Germany) stent graft, which is approved for coronary interventions, was successfully deployed over a coaxial guiding system during the emergent treatment of the false aneurysm. The patient tolerated the procedure well and nasal bleeding did not recur after the procedure. At one-year angiographic follow-up, the stent graft was patent and there was no evidence of recanalization of the false aneurysm.

Context.—: The nature and associations of gallbladder (GB) "adenomyoma" (AM) remain controversial. Some studies have attributed up to 26% of GB carcinoma to AMs., Objective.—: To examine the true frequency, clinicopathologic characteristics, and neoplastic changes in GB AM., Design.—: Cholecystectomy cohorts analyzed were 1953 consecutive cases, prospectively with specific attention to AM; 2347 consecutive archival cases; 203 totally embedded GBs; 207 GBs with carcinoma; and archival search of institutions for all cases diagnosed as AM., Results.—: Frequency of AM was 9.3% (19 of 203) in totally submitted cases but 3.3% (77 of 2347) in routinely sampled archival tissue. A total of 283 AMs were identified, with a female to male ratio = 1.9 (177:94) and mean size = 1.3 cm (range, 0.3-5.9). Most (96%, 203 of 210) were fundic, with formed nodular trabeculated submucosal thickening, and were difficult to appreciate from the mucosal surface. Four of 257 were multifocal (1.6%), and 3 of 257 (1.2%) were extensive ("adenomyomatosis"). Dilated glands (up to 14 mm), often radially converging to a point in the mucosa, were typical. Muscle was often minimal, confined to the upper segment. Nine of 225 (4%) revealed features of a duplication. No specific associations with inflammation, cholesterolosis, intestinal metaplasia, or thickening of the uninvolved GB wall were identified. Neoplastic change arising in AM was seen in 9.9% (28 of 283). Sixteen of 283 (5.6%) had mural intracholecystic neoplasm; 7 of 283 (2.5%) had flat-type high-grade dysplasia/carcinoma in situ. Thirteen of 283 cases had both AM and invasive carcinoma (4.6%), but in only 5 of 283 (1.8%), carcinoma arose from AM (invasion was confined to AM, and dysplasia was predominantly in AM)., Conclusions.—: AMs have all the features of a malformative developmental lesion, and may not show a significant muscle component (ie, the name "adeno-myoma" is partly a misnomer). While most are innocuous, some pathologies may arise in AMs, including intracholecystic neoplasms, flat-type high-grade dysplasia or carcinoma in situ, and invasive carcinoma (1.8%, 5 of 283). It is recommended that gross examination of GBs include serial slicing of the fundus for AM detection and total submission if one is found., (© 2024 College of American Pathologists.)

Background: Male breast cancer (MBC) accounts for one percent of all breast cancers. Due to the lack of awareness and routine screening programs, most patients present with systemic disease at the time of diagnosis with low overall survival., Objectives: This study aims to investigate the prognostic factors of male breast cancer and its correlation with established prognostic parameters and patient outcomes., Methods: Thirty-eight male breast cancer patients are identified from the MKA Breast Cancer Clinic database, and their corresponding clinical and pathological characteristics are obtained. Cut-off values of 1% and 10% are applied to further classify ER and PR results., Results: Older men are more likely to develop MBC than younger men and are more likely to have spread to axillary lymph nodes. Invasive ductal carcinoma is a more common histologic type in MBC. All the tested patients have ER and PR positivity. Distant metastasis developed in 17/38 (44.7%) patients. Bone metastasis is seen commonly in metastatic MBC., Conclusions: According to our cohort, MBC is seen in older males, presents in later stages, and shows hormone receptor positivity and a tendency to bone involvement. MBC is a heterogenous but distinct biological entity requiring a specific clinical and pathological approach.

Objective: Craniopharyngiomas are locally invasive neoplasms, and they cause potential lifelong morbidity because of their tendency for local recurrence. Despite advancements in endoscopic techniques, gross-total resection (GTR) of tumors with invasion or adhesion to important surrounding anatomical structures is extremely difficult. The authors present a single-center study that evaluated the impact of the endoscopic endonasal approach (EEA) on the surgical outcomes of pediatric craniopharyngiomas, the factors affecting the resection rate, and recurrence., Methods: A total of 44 pediatric patients (age ≤ 18 years) who were treated via the EEA for craniopharyngioma from August 1997 to June 2022, as well as their 53 operations, were included in this study. The preoperative radiological configuration and surgical data of these cases were assessed. Also, preoperative and postoperative clinical (endocrinologic, neurological, and ophthalmological), hypothalamic, physical and social development, and neurocognitive assessment data were described., Results: In total, 37 cases (69.8%) had no history of operation beforehand. The most common symptoms at presentation were endocrine disturbances (98.1%), headache without vomiting (84.3%), and visual disturbance (51%). Cases were classified as infrasellar (1.9%), sellar (32.1%), sellar-suprasellar (52.8%), and suprasellar (13.2%) localization. GTR was achieved in 34/53 cases (64.1%). The rate of GTR was higher in infrasellar and sellar tumors compared with sellar-suprasellar and suprasellar tumors (p = 0.003), and preoperative hypothalamic involvement was associated with lower likelihood of GTR (p = 0.024). Moreover, with experience, the rate of GTR increased (p = 0.037). Postoperative complications, other than endocrine impairment, occurred in 10/53 cases (18.9%). The mean duration of follow-up was 53.57 months. At follow-up, 21/53 (39.6%) cases presented with tumor recurrence. The 5-year progression-free survival (PFS) rate was 48.5%. There was a statistically significant difference between the GTR and other-than-GTR groups in terms of PFS (p < 0.001). According to univariate analysis, smaller tumor (p = 0.017), infrasellar and sellar localization (p = 0.031), and GTR (p < 0.001) were significantly associated with decreased rate of recurrence. Also, there was a statistically significant association between the recurrence rate and adhesion strength of the tumor (p < 0.001)., Conclusions: This retrospective cohort study revealed surgical indications for EEA, as well as factors affecting the resection rate, recurrence, and quality of life during the follow-up period of the included cases. The authors believe that GTR should be the goal for craniopharyngioma treatment, but the authors' treatment approach was to provide a balance between radical surgery with maximum safety and adjuvant treatment for long-term disease control.

Background: To evaluate the effect of sodium-glucose cotransporter-2 inhibitor treatment on choroidal vascular parameters in patients with type 2 diabetes mellitus (T2DM)., Methods: Twenty eyes of 20 patients with T2DM without diabetic retinopathy and 20 eyes of 20 age- and sex-matched patients as the control group were included in the study. The patients were evaluated using enhanced depth imaging optic coherence tomography before treatment and at the third month of treatment. The choroidal images were binarized into luminal areas (LAs) and stromal areas (SAs). The choroidal vascularity index (CVI) was defined as the ratio of the LA to the total circumscribed choroid area (TCA)., Results: The mean age of the patients was 56.65±8.41 years. The patients' mean disease duration was 6.65±5.72 years, the mean HbA1c level was 8.89±1.62%, and the mean body mass index was 33.13±4.84 kg/m 2 . The subfoveal TCA, subfoveal LA, subfoveal SA, total TCA, total LA, and total SA values ​​of the patient group were found to be significantly lower than those of the control group (p = 0.006, p = 0.003, p = 0.028, p = 0.001, p = 0.001, and p = 0.006, respectively). There was a significant increase in the subfoveal TCA, subfoveal LA, subfoveal SA, subfoveal CVI, total TCA, total LA, and total SA values ​​after empagliflozin treatment compared to before empagliflozin treatment (p = 0.005, p = 0.003, p = 0.021, p = 0.032, p < 0.001, p < 0.001, and p = 0.001 respectively)., Conclusions: Empagliflozin provides an improvement in diabetic choroidal changes through its effect on choroidal vascularity parameters., Competing Interests: Declaration of Competing Interest The authors declare there is no conflict of interests., (Copyright © 2023 Elsevier B.V.

Objective: Due to the high increase in rate of autism, it has gained great importance to determine the etiology of autism spectrum disorder. The purpose of our study was to assess the role of Candida albicans as a risk factor to cause autism behavior., Methods: We searched Scopus, PubMed, Web of Science and PsycINFO for articles up to December, 2021. The studies involving children diagnosed with autism spectrum disorder were included. Children' outcomes were selected as Candida albicans (positive) and Candida albicans (negative). Odds ratios were reported using fixed-effect and random-effect meta-analysis. The heterogeneity was assessed by the Chi-square test and Higgins' I 2 test . The publication bias was examined via funnel plot and Hegger's test ., Results: Our meta-analysis was conducted based on 254 diagnosed with Autism Spectrum Disease cases and 161 healthy cases from 4 studies. Compared to the healthy cases, the odds of presence of Candida albicans (OR=7.21; 95% CI: 3.75-13.85; p<0.001) were higher in those diagnosed with autism spectrum disorder., Conclusion: This study as a whole showed that children diagnosed with autism spectrum disorder have higher frequency of the presence of the fungus Candida albicans. Therefore, Candida albicans may be an etiological factor for the autistic behavior in children., Competing Interests: Authors declare that they have no conflict of interest., (© 2023 Ozgur EG et al.)

Context.—: Tumoral (grossly visible) intraductal neoplasms of the bile ducts are still being characterized., Objective.—: To investigate their morphologic, immunohistochemical, and molecular features., Design.—: Forty-one cases were classified as gastric-, intestinal-, pancreatobiliary-type intraductal papillary neoplasm (IPN), intraductal oncocytic papillary neoplasm (IOPN), or intraductal tubulopapillary neoplasm (ITPN) on the basis of histology. All neoplasms were subjected to targeted next-generation sequencing., Results.—: The mean age at diagnosis was 69 years (42-81 years); male to female ratio was 1.3. Most neoplasms (n = 23, 56%) were extrahepatic/large (mean size, 4.6 cm). The majority (n = 32, 78%) contained high-grade dysplasia, and 68% (n = 28) revealed invasion. All gastric-type IPNs (n = 9) and most ITPNs/IOPNs showed consistent colabeling for CK7/MUC6, which was less common among others (P = .004). Intestinal-type IPNs (n = 5) showed higher rates of CK20 expression than others (P < .001). Overall, the most commonly mutated genes included TP53 and APC, while copy number variants affected ELF3 and CDKN2A/B. All gastric-type IPNs contained an alteration affecting the Wnt signaling pathway; 7 of 9 (78%) showed aberrations in the MAPK pathway. Mutations in APC and KRAS were common in gastric-type IPNs as compared with others (P = .01 for both). SMAD4 was more frequently mutated in intestinal-type IPNs (P = .02). Pancreatobiliary-type IPNs (n = 14) exhibited frequent alterations in tumor suppressor genes including TP53, CDKN2A/B, and ARID2 (P = .04, P = .01 and P = .002, respectively). Of 6 IOPNs analyzed, 3 (50%) revealed ATP1B1-PRKACB fusion. ITPNs (n = 6) showed relatively few recurrent genetic aberrations. Follow-up information was available for 38 patients (median, 58.5 months). The ratio of disease-related deaths was higher for the cases with invasion (56% versus 10%)., Conclusions.—: Tumoral intraductal neoplasms of the bile ducts, similar to their counterparts in the pancreas, are morphologically and genetically heterogeneous., (© 2023 College of American Pathologists.)

Objective: This epidemiology study was conducted to determine the musculoskeletal system problems of children working in the automotive industry and related factors affecting them in the province of Şanlıurfa, the Turkish province where the child population is the highest at 44.9%., Design and Methods: A cross-sectional descriptive type study of 256 children aged 7-17 years working in Şanlıurfa Evren Auto Industry Site and Birecik Fırat Auto Industry Site was carried out between April and September 2021., Results: The majority (55.9%) of the children spent most of their time afoot while working and had musculoskeletal symptoms, with a duration of more than one year. The body areas with the most symptoms were the waist, feet, and hands, respectively. These symptoms had not occurred before a child started working and were affected by the posture they worked in, and their daily working and sleep hours., Conclusion: Public health nurses are in a position to ensure that tetanus vaccination of working children, employment examinations, routine health checks, and necessary personal protective equipment are available. They can also work to ensure that children work for legal periods, get paid their wages, have health insurance, receive apprenticeship training, and only start working when they reach the age of being an apprentice or apprentice candidate., (© 2023 Wiley Periodicals LLC.)

Objective: Screening tests are recommended to identify genetic defects, chromosomal aneuploidies, and structural birth defects. Sonographic and maternal serum-based options are available for the risk assessment of aneuploidy in the first and/or second trimester. Also, invasive diagnostic methods, such as amniocentesis, are used for prenatal diagnosis, but these methods carry a tangible risk to the fetus. However, in recent years, circulating fetal nucleic acids have a promising moleculer tool in the noninvasive prenatal diagnosis of fetal chromosomal aneuploidies. In this study, we aimed to explore the usability of microRNAs (miRNAs) in this process of prenatal diagnosis., Methods: Fourteen pregnant patients who were found to be carrying fetuses with congenital anomalies were designated as the patient group; 16 pregnant women identified as being at risk of carrying children with such anomalies-but whose fetuses were later found to be anomaly-free-were assigned to control group 1; and 13 pregnant women who had been screened and who had not been identified as being at risk made up control group 2. An analysis of miRNA expression, isolated from maternal plasma and amniotic fluid samples, was performed by quantitative real-time polymerase chain reaction., Results: It was found that hsa-miR-629-5p, hsa-miR-320c, hsa-miR-21-5p, hsa-let-7c-5p, hsa-miR-98-5p, hsa-miR-486-5p, hsa-miR-4732-5p, and hsa-miR-181a-5p levels increased in the patient group's maternal plasma compared to that of the control group., Conclusion: In light of these data, we believe that miRNAs may have an important role in the noninvasive prenatal diagnosis of fetal birth defects, especially Down syndrome.

Background: One of the main causes of unsatisfactory outcomes after unilateral blepharoptosis surgery is asymmetry of the upper eyelid height, which occurs as a result of a contralateral eyelid droop. Therefore, the authors evaluated the efficacy of Müller muscle-conjunctival resection (MMCR) for the treatment of contralateral ptosis following unilateral external levator advancement (ELA)., Methods: This study analyzed 26 eyelids of 26 patients with upper eyelid height asymmetry following unilateral ELA who underwent contralateral MMCR retrospectively. The phenylephrine test was performed before ELA and before MMCR. The main outcome measures were symmetry outcomes and clinical outcomes., Results: The mean patient age was 55.81 ± 7.98 years (range, 44 to 70 years); 15 were female (57.7%). The Hering dependency was observed in 13 of the patients (50%) before ELA. An adequate response to phenylephrine was observed before MMCR but not before ELA. Symmetry outcomes after MMCR were perfect (<0.5 mm), good (≥0.5 mm and <1 mm), and fair (≥1 mm) in seven, 17, and two patients, respectively. An optimal upper eyelid height was noted in 47 of the 52 eyelids after the MMCR, whereas three of the 52 eyelids had minimal overcorrection, and two eyelids had undercorrection. The mean change in marginal reflex distance 1 of the contralateral eyelid droop was greater for patients with than without the Hering dependency ( P < 0.0001) after ELA but not after MMCR. Two patients (7.6%) underwent revision ELA surgery., Conclusion: MMCR and use of the phenylephrine test to predict the eyelid position may represent an alternative approach in patients who require management of contralateral ptosis following unilateral ELA., Clinical Question/level of Evidence: Therapeutic, IV., (Copyright © 2023 by the American Society of Plastic Surgeons.)

Objectives: The aim of this study was to compare the effectiveness of 3 methods (Buzzy, ShotBlocker, and DistrACTION Cards) in reducing pain and anxiety while taking venous blood samples in children., Methods: The study population consisted of children aged 9 to 12 years admitted to the Child Health and Diseases Department in a Faculty of Medicine in Turkey. The sample of the study consisted of 242 children (Buzzy = 60, ShotBlocker = 61, DistrACTION Cards = 60, control = 61) who met the patient selection criteria and agreed to participate in the study. The data were obtained using an Information Form, the State-Trait Anxiety Inventory for Children, visual analog scale, and the Faces Pain Scale-Revised., Design: This article is an experimental randomized controlled study., Results: During venous blood collection, the scores of visual analog scale were significantly lower in ShotBlocker, Buzzy, and DistrACTION Cards groups than the control group. It was also observed that the control group experienced more anxiety than the other groups., Conclusions: Methods such as Buzzy, ShotBlocker, and DistrACTION Cards can be used to reduce the anxiety and pain of children during painful procedures such as blood collection and vascular access. Among these methods, "Buzzy" and "DistrACTION Cards" can be preferred as it is equally effective, and then ShotBlocker can be preferred., Competing Interests: Disclosure: The authors declare no conflict of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

Background: Student mobility across borders poses challenges to health systems at the university and country levels. International students suffer from stress more than their local peers, however, do not seek help or underutilize existing help offers. Some barriers to help-seeking among international students are insufficient information regarding the health offers, stigma, and language, which might be overcome via culturally adapted internet and mobile-based interventions (IMI)., Method: A randomized controlled feasibility trial with a parallel design assessed the feasibility and potential efficacy of an online mindfulness intervention adapted for international university students. Participants were randomized into either an adapted online mindfulness intervention (StudiCareM-E) (IG, n = 20) or a waitlist control group (WL, n = 20). Participants were assessed at baseline (t0) and eight-week post-randomization (t1). The feasibility of StudiCareM-E was evaluated regarding intervention adherence, client satisfaction, and potential negative effects. The potential efficacy of StudiCareM-E was measured by means of the level of mindfulness, perceived stress, depression, anxiety, presenteeism, and wellbeing. Efficacy outcomes were evaluated with regression models on the intention-to-treat (ITT) sample (n = 40), adjusting for the baseline values., Results: Participants' formative feedback suggested improvements in the content of the IMI. There were no crucial negative effects compared to WL. Assessment dropout was 35% (IG: 50%: WL: 20%), and intervention dropout was 60%. StudiCareM-E yielded significant improvements in mindfulness (β = .34), well-being (β = .37), and anxiety (β = -.42) compared to WL., Conclusion: StudiCareM-E might be used among culturally diverse international student populations to improve their well-being. Future studies might carefully inspect the extent of the adaptation needs of their target group and design their interventions accordingly., Competing Interests: The authors have declared that no competing interests exist.

Objective: In the present study, we investigated the expression of CD56, ADAM17 and FGF21 antibodies (Ab), which we think have an effect on the pathophysiology of preeclampsia (PE), in pregnant patients with healthy placentas and placentas with PE. The expression of these antibodies has been investigated in a limited amount of former research, but their role in PE has not yet been clarified. With this study, we aimed to contribute to the elucidation of the pathophysiology of PE and the detection of new target molecules for treatment. Materials and Methods: Parturients with singleton pregnancy at 32 weeks or above without any maternal or fetal pathology who were admitted to the Department of Obstetrics and Gynecology, Zonguldak Bülent Ecevit University Practice and Research Hospital between 11 January 2020 and 7 January 2022 were included in the present study. Pregnant women with coexisting disease or a pathology related to the placenta (ablation placenta, vasa previa, hemangioma, etc.) were excluded. CD56, ADAM17 and FGF21 antibodies were histopathologically and immunohistochemically detected in 60 placentas with PE (study group) and 43 healthy placentas (control group). Results: CD56, ADAM17 and FGF21 proteins were all more intensely expressed in preeclamptic placentas and a statistically significant difference was found between the two groups for all three antibodies ( p < 0.001). Deciduitis, perivillous fibrin deposition, intervillous fibrin, intervillous hemorrhage, infarct, calcification, laminar necrosis and syncytial node were found to be significantly more common in the study group ( p < 0.001). Conclusions: We observed that CD56, ADAM17 and FGF21 expressions increased in preeclamptic placentas. These Ab may be responsible for the pathogenesis of PE, which can be illuminated with further studies.

In polaritons, the properties of matter are modified by mixing the molecular transitions with light modes inside a cavity. Resultant hybrid light-matter states exhibit energy level shifts, are delocalized over many molecular units, and have a different excited-state potential energy landscape, which leads to modified exciton dynamics. Previously, non-Hermitian Hamiltonians have been derived to describe the excited states of molecules coupled to surface plasmons (i.e., plexcitons), and these operators have been successfully used in the description of linear and third order optical response. In this article, we rigorously derive non-Hermitian Hamiltonians in the response function formalism of nonlinear spectroscopy by means of Feshbach operators and apply them to explore spectroscopic signatures of plexcitons. In particular, we analyze the optical response below and above the exceptional point that arises for matching transition energies for plasmon and molecular components and study their decomposition using double-sided Feynman diagrams. We find a clear distinction between interference and Rabi splitting in linear spectroscopy and a qualitative change in the symmetry of the line shape of the nonlinear signal when crossing the exceptional point. This change corresponds to one in the symmetry of the eigenvalues of the Hamiltonian. Our work presents an approach for simulating the optical response of sublevels within an electronic system and opens new applications of nonlinear spectroscopy to examine the different regimes of the spectrum of non-Hermitian Hamiltonians.

Objective: Eating Disorder-15 (ED-15) is a self-report scale recommended for use to evaluate weekly progress and treatment results in eating disorders. This research aims to examine the factor structure, psychometric properties, validity, and reliability of the Turkish version of ED-15 (ED-15-TR) for clinical and non-clinical samples., Method: Translation-back translation method was used for language equivalence of ED-15-TR. The research was conducted with a total of 1049 volunteers, with two sample groups as non-clinical (n=978) and clinical (n=71). The participants completed an information form, ED-15-TR, Eating Disorder Examination Scale (EDE-Q), and Beck Depression Inventory (BDI). Three hundred fifty-two participants from the non-clinical group and 18 from the clinical group completed ED-15-TR again within a week., Results: Factor analysis confirmed the two-factor structure of ED-15- TR. Cronbach's alpha value was 0.911 (0.773, and 0.904 for the two subscales respectively), the intraclass correlation coefficient for testretest reliability was 0.943 in the clinical group (0.906, and 0.942 for the two subscales respectively); 0.777 (0.699, and 0.776 for the two subscales respectively) in the non-clinical group (for all p<0.001). The high level of a positive correlation between ED-15-TR and EDE-Q supported concurrent validity., Conclusion: This research indicates that ED-15-TR is an acceptable, valid, and reliable self-report scale for Turkish society.

Significance: Visual acuity may be limited after endothelial keratoplasty in Fuchs' endothelial corneal dystrophy. This may be due to increased anterior high-order aberrations that persist after endothelial keratoplasty. It is not clear at what stage these aberrations begin. We aimed to evaluate how subclinical corneal edema affects anterior corneal high-order aberrations., Purpose: We aimed to evaluate anterior corneal high-order aberrations according to the presence of subclinical corneal edema in Fuchs' endothelial corneal dystrophy using Scheimpflug topography., Methods: All the patients underwent corneal topography (Sirius Scheimpflug-Placido disc camera; CSO Ophthalmic, Scandicci, Italy). Fifty-two eyes of 31 patients with Fuchs' endothelial corneal dystrophy and 52 eyes of 35 patients without corneal problems were included. In addition, patients with Fuchs' endothelial corneal dystrophy were divided into two groups according to subclinical corneal edema as with Fuchs' endothelial corneal dystrophy-edema and Fuchs' endothelial corneal dystrophy-nonedema. Subclinical corneal edema was defined based on the presence of at least two of three findings of the loss of regular isopachs, displacement of the thinnest point of the cornea, and posterior depression. High-order aberrations were expressed as Zernike polynomials in the 4- and 6-mm optical zone., Results: We found that subclinical corneal edema in Fuchs' endothelial corneal dystrophy caused a larger 4-mm trefoil II and a smaller 6-mm spherical aberration II measurements than the nonedema group. The 6-mm total high-order aberrations, 6-mm coma aberration, and 4- and 6-mm trefoil II aberration measurements were larger, and the 6-mm spherical aberration II was smaller in Fuchs' endothelial corneal dystrophy patients with edema compared with the healthy eyes., Conclusions: The presence of subclinical corneal edema in Fuchs' endothelial corneal dystrophy results in larger 4-mm trefoil II and smaller 6-mm spherical aberration II measurements. More patients with intermediate values are needed to evaluate the effect of these aberrations on visual acuity., Competing Interests: Conflict of Interest Disclosure: None of the authors have reported a financial conflict of interest., (Copyright © 2022 American Academy of Optometry.)

There are highly conflicting data on relative frequency (2-32%), prognosis, and management of pT1b-gallbladder carcinoma (GBC), with 5-year survival ranging from > 90% in East/Chile where cholecystectomy is regarded as curative, versus < 50% in the West, with radical operations post-cholecystectomy being recommended by guidelines. A total of 473 in situ and invasive extensively sampled GBCs from the USA (n = 225) and Chile (n = 248) were re-evaluated histopathologically per Western invasiveness criteria. 349 had invasive carcinoma, and only 24 were pT1. Seven cases previously staged as pT1b were re-classified as pT2. There were 19 cases (5% of all invasive GBCs) qualified as pT1b and most pT1b carcinomas were minute (< 1mm). One patient with extensive pTis at margins (but pT1b focus away from the margins) died of GBC at 27 months, two died of other causes, and the remainder were alive without disease (median follow-up 69.9 months; 5-year disease-specific survival, 92%). In conclusion, careful pathologic analysis of well-sampled cases reveals that only 5% of invasive GBCs are pT1b, with a 5-year disease-specific survival of > 90%, similar to findings in the East. This supports the inclusion of pT1b in the "early GBC" category, as is typically done in high-incidence regions. Pathologic mis-staging of pT2 as pT1 is not uncommon. Cases should not be classified as pT1b unless extensive, preferably total, sampling of the gallbladder to rule out a subtle pT2 is performed. Critical appraisal of the literature reveals that the Western guidelines are based on either SEER or mis-interpretation of stage IB cases as "pT1b." Although the prognosis of pT1b-GBC is very good, additional surgery (radical cholecystectomy) may be indicated, and long-term surveillance of the biliary tract is warranted., (© 2022.

Objective: The aim of this study was to compare the levels of pain developed during intramuscular injections to the laterofemoral and ventrogluteal regions in children., Methods: The study population consisted of all children aged between 7 and 12 years who presented to the pediatric emergency clinic of a hospital. The sample consisted of 62 children who met the inclusion criteria and agreed to participate in the study, and the children were randomly assigned to each group (laterofemoral n=31, ventrogluteal n=31). "Buzzy" and "deep breathing" were applied to children in both groups to relieve pain during the procedure. The data were obtained using an Information Form, a visual analog scale, and the Facial Pain Scale-Revised., Results: It was determined that the children in the ventrogluteal group during the intramuscular injections had lower visual analog scale and faces pain scale-revised scores immediately after the procedure compared with the vastus lateralis group, that is, they experienced less pain, and the difference between the two groups was significant (p<0.001)., Conclusion: In children, it is recommended to choose the less painful ventrogluteal region for intramuscular injection and to inform health professionals about it.

Medullary carcinomas have not yet been fully characterized in the ampulla. Here, 359 ampullary carcinomas (ACs) were reviewed and 11 medullary-type carcinomas (3%) were found and analyzed. In addition to the diagnostic medullary pattern, 6 showed focal mucinous and 8 had focal abortive gland-like formations. They occurred in younger patients (57 versus 65 y; P = .02), had larger invasion size (mean, 3.2 versus 1.9 cm; P = .01), formed nodular polypoid or plaque-like tumors, and often lacked preinvasive component. In addition to the lymphoplasmacytic infiltrates, they also had prominent eosinophils in 5 of 11 cases. Eight were papilla Vateri-NOS (not otherwise specified) tumors, 2 were ampullary-duodenal origin, 1 had a minor intra-ampullary papillary tubular neoplasm component, and none were ampullary-ductal. Although they had pushing-border infiltration, perineural and vascular invasion was common. They were strongly associated with DNA mismatch repair (MMR) protein deficient (7/11, 64%). The 5-yr survival rate (53%) appeared to be comparable with, and perhaps even better than that of nonmedullary ACs (47%), although this did not reach statistical significance (P = .47). Programmed cell death ligand-1 (PD-L1) expression levels were assessed in 8, and all 4 that were MMR deficient were positive both by combined positive score (CPS) ≥1 and tumor proportion score (TPS) ≥1, and of the 4 MMR proficient cases, 3 were positive by CPS; 2 by TPS. Overall, only 1 of the 8 available for analysis failed to show PD-L1 positivity by CPS. In contrast, nonmedullary MMR-deficient carcinomas expressed PD-L1 in only 33% of tumors by CPS, and none by TPS. One medullary carcinoma was also EBV associated. Unlike 'medullary carcinomas' of the kidney, INI1 was retained in all 8 cases tested. In conclusion, medullary carcinomas are 3% of ACs, have a strong association with MMR-D, and may be less aggressive despite their larger size. PD-L1 expression appears to be closely associated with medullary ACs regardless of MMR status, and thus targeted therapies can be considered for all medullary carcinomas of this site., (Copyright © 2022 Elsevier Inc.

Objective: To examine the effect of bariatric surgery on the macular and peripapillary choroid in the late postoperative period in young patients with morbid obesity and compare them with a healthy control group., Methods: This prospective controlled study included 50 eyes of 25 young patients with morbid obesity and 50 eyes of 25 age and sex-matched healthy controls. Sleeve gastrectomy was performed on all patients with obesity. Preoperative and 6-month postoperative macular and peripapillary choroidal thickness, total choroidal area (TCA), luminal area (LA), and choroidal vascularity index (CVI) were performed. Results were compared with healthy controls by using enhanced depth imaging optical coherence tomography., Results: Choroidal thickness and CVI values were smaller in patients with obesity in both macular and peripapillary areas compared with the healthy control group (both p < 0.001). There was a statistically significant increase in the macular and peripapillary choroidal thickness of patients with obesity when the preoperative and the postoperative 6-month values after bariatric surgery were compared (both p < 0.001). Also, it was found that bariatric surgery increased TCA and LA values in the macular and all sectors of peripapillary areas (all p < 0.001), and CVI values in the temporal and nasal peripapillary sectors (p = 0.007, p = 0.012, respectively)., Conclusions: Bariatric surgery was found to increase the macular and peripapillary choroidal thickness and the nasal and temporal peripapillary CVI values in young patients with morbid obesity in the late period. To the best of our knowledge, the current study has shown for the first time that bariatric surgery affects peripapillary choroid and CVI values., (Copyright © 2022 Canadian Ophthalmological Society.

Purpose: The aim of this study was to investigate changes in both macular and peripapillary retinal microcirculation in the subclinical period of systemic lupus erythematosus (SLE) patients and to assess the relationship of these changes with disease activity, damage index, renal involvement, and use of hydroxychloroquine (HCQ)., Methods: Sixty eyes of 60 SLE patients and 60 age-matched, healthy controls were evaluated with optical coherence tomography angiography (OCTA). Vessel densities, structural parameters, and foveal avascular zone (FAZ) assesments were made., Results: There was no significant correlation between activity and damage index and all regions of both superficial (SCP-VD) and deep capillary plexus vessel densities (DCP-VD) in the SLE group. There were no significant difference between groups in terms of FAZ, structural parameters, and radial peripapillary capillary vessel densities (RPC-VD). The mean SCP-VD and DCP-VD of most regions showed a significant decrease in the SLE group, except for parafovea superior and parafovea temporal. The decrease in vessel density (VD) in the perifoveal regions of DCP-VD in SLE patients was remarkable. DCP-VD showed good specifity and sensitivity in detecting vascular changes in SLE patients with whole image area under the curve (AUC) = 0.671, p < 0.001, odds ratio (OR) = 0.909, p = 0.009, and perifovea AUC = 0.671, p < 0.001, OR = 0.918, p = 0.012. Similarly, the SCP-VD whole image AUC = 0.609, p = 0.037, and OR = 0.825, p = 0.018 and perifovea AUC = 0.608, p = 0.037, and OR = 0.918, p = 0.012. The DCP-VD of perifovea superior showed a diagnostic accuracy for discrimination between SLE patients with and without nephritis (AUC = 0.671, p = 0.016). The SCP-VD and cumulative dose of HCQ demonstrated significant negative correlation in the SLE group (whole image, r =  - 0.332, p = 0.010)., Conclusions: SLE patients without ocular involvement had vascular changes that were particularly evident in the DCP and primarily in the perifovea. The perifovea superior of DCP had diagnostic utility in patients with nephropathy., (© 2022. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

The literature on liver cysts is highly conflicting, mostly owing to definitional variations. Two hundred and fifty-eight ≥1 cm cysts evaluated pathologically using updated criteria were classifiable as: I. Ductal plate malformation related (63%); that is, cystic bile duct hamartoma or not otherwise specified-type benign biliary cyst (35 with polycystic liver disease). These were female predominant (F/M=2.4), large (10 cm), often multifocal with degenerative/inflammatory changes and frequently misclassified as "hepatobiliary cystadenoma." II. Neoplastic (13%); 27 (10.5%) had ovarian-type stroma (OTS) and qualified as mucinous cystic neoplasm (MCN) per World Health Organization (WHO). These were female, solitary, mean age 52, mean size 11 cm, and 2 were associated with carcinoma (1 in situ and 1 microinvasive). There were 3 intraductal papillary neoplasms, 1 intraductal oncocytic papillary neoplasm, 1 cystic cholangiocarcinoma, and 2 cystic metastasis. III. Infectious/inflammatory (12%). These included 23 hydatid cysts (including 2 Echinococcus alveolaris both misdiagnosed preoperatively as cancer), nonspecific inflammatory cysts (abscesses, inflammatory cysts: 3.4%). IV. Congenital (7%). Mostly small (<3 cm); choledochal cyst (5%), foregut cyst (2%). V. Miscellaneous (4%). In conclusion, hepatic cysts occur predominantly in women (3/1), are mostly (90%) non-neoplastic, and seldom (<2%) malignant. Cystic bile duct hamartomas and their relative not otherwise specified-type benign biliary cysts are frequently multifocal and often misdiagnosed as "cystadenoma/carcinoma." Defined by OTS, MCNs (the true "hepatobiliary cystadenoma/carcinoma") are solitary, constitute only 10.5% of hepatic cysts, and have a significantly different profile than the impression in the literature in that essentially all are perimenopausal females, and rarely associated with carcinoma (7%). Since MCNs can only be diagnosed by demonstration of OTS through complete microscopic examination, it is advisable to avoid the term "cystadenoma/cystadenocarcinoma" solely based on radiologic examination, and the following simplified terminology would be preferable in preoperative evaluation to avoid conflicts with the final pathologic diagnosis: (1) noncomplex (favor benign), (2) complex (in 3 subsets, as favor benign, cannot rule out malignancy, or favor malignancy), (3) malignant features., Competing Interests: Conflicts of Interest and Source of Funding: The authors have disclosed that they have no significant relationships with, or financial interest in, any commercial companies pertaining to this article., (Copyright © 2022 Wolters Kluwer Health, Inc.

The advancing edge profile is a powerful determinant of tumor behavior in many organs. In this study, a grading system assessing the tumor-host interface was developed and tested in 181 pancreatic neuroendocrine tumors (PanNETs), 63 of which were <=2 cm. Three tumor slides representative of the spectrum (least, medium, and most) of invasiveness at the advancing edge of the tumor were selected, and then each slide was scored as follows. Well-demarcated/encapsulated, 1 point; Mildly irregular borders and/or minimal infiltration into adjacent tissue, 2 points; Infiltrative edges with several clusters beyond the main tumor but still relatively close, and/or satellite demarcated nodules, 3 points; No demarcation, several cellular clusters away from the tumor, 4 points; Exuberantly infiltrative pattern, scirrhous growth, dissecting the normal parenchymal elements, 5 points. The sum of the rankings on the three slides was obtained. Cases with scores of 3-6 were defined as "non/minimally infiltrative" (NI; n = 77), 7-9 as "moderately infiltrative" (MI; n = 68), and 10-15 as "highly infiltrative" (HI; n = 36). In addition to showing a statistically significant correlation with all the established signs of aggressiveness (grade, size, T-stage), this grading system was found to be the most significant predictor of adverse outcomes (metastasis, progression, and death) on multivariate analysis, more strongly than T-stage, while Ki-67 index did not stand the multivariate test. As importantly, cases <=2 cm were also stratified by this grading system rendering it applicable also to this group that is currently placed in "watchful waiting" protocols. In conclusion, the proposed grading system has a strong, independent prognostic value and therefore should be considered for integration into routine pathology practice after being evaluated in validation studies with larger series., (© 2021.

Purpose: In this study, we aimed to determine the frequency of different intestinal microorganisms of patients with normal pregnancies and HG and to compare these frequencies between the two groups., Materials and Methods: This case-control study was carried out in Baskent University Department of Obstetrics and Gynecology and included 20 patients; 10 of whom had normal pregnancies and 10 of whom had HG. A stool flora scan was routinely planned for all patients. Transient and continuous fecal bacteria and fungal flora were analyzed. All data were evaluated statistically and their relationships with clinical condition were discussed., Results: The study group consisted of 20 pregnant women with a mean age of 31.5 years. All patients were nonsmokers and free of chronic diseases and of any medications. Aerobic and anaerobic bacteria groups, fungal colonies, and parasites were examined and bowel pH values were measured separately for each patient. Bacterial and fungal species outside the reference ranges were recorded for each patient. There was a statistically significant increase in Clostridium spp. ( p :.01) and Candida spp. ( p :.033) and a statistically significant decrease in Bifidobacterium spp.( p :.008) in patients with HG compared to women with normal pregnancies. There was a significant difference between the group with HG and the group with normal pregnancies in terms of flora dysbiosis ( p :.001)., Conclusion: Our results suggest that gut dysbiosis may be a factor in HG. The effect of the severity of gut dysbiosis on the disease may be the subject of future studies.

Carbon quantum dots (CDs) have recently received a tremendous amount of interest owing to their attractive optical properties. However, CDs have broad absorption and emission spectra limiting their application ranges. We herein, for the first time, show synthesis of water-soluble red emissive CDs with a very narrow line width (∼75 meV) spectral absorbance and hence demonstrate strong coupling of CDs and plasmon polaritons in liquid crystalline mesophases. The excited state dynamics of CDs has been studied by ultrafast transient absorption spectroscopy, and CDs display very stable and strong photoluminescence emission with a quantum yield of 35.4% and a lifetime of ∼2 ns. More importantly, we compare J -aggregate dyes with CDs in terms of their absorption line width, photostability, and ability to do strong coupling, and we conclude that highly fluorescent CDs have a bright future in the mixed light-matter states for emerging applications in future quantum technologies.

The topological structure associated with the branch point singularity around an exceptional point (EP) can provide tools for controlling the propagation of light. Through use of graphene-based devices, we demonstrate the emergence of EPs in an electrically controlled interaction between light and a collection of organic molecules in the terahertz regime at room temperature. We show that the intensity and phase of terahertz pulses can be controlled by a gate voltage, which drives the device across the EP. Our electrically tunable system allows reconstruction of the Riemann surface associated with the complex energy landscape and provides topological control of light by tuning the loss imbalance and frequency detuning of interacting modes. Our approach provides a platform for developing topological optoelectronics and studying the manifestations of EP physics in light-matter interactions.

Health promotion interventions offer great potential in advocating a healthy lifestyle and the prevention of diseases. Some barriers to communicating health promotion to people of certain cultural groups might be overcome via the internet- and mobile-based interventions (IMI). This systematic review and meta-analysis aims to explore the effectiveness of culturally adapted IMI for health promotion interventions among culturally diverse populations. We systematically searched on Cochrane Central Register of Controlled Trials (CENTRAL), EbscoHost/MEDLINE, Ovid/Embase, EbscoHost/PsychINFO, and Web of Science databases in October 2020. Out of 9438 records, 13 randomized controlled trials (RCT) investigating culturally adapted health promotion IMI addressing healthy eating, physical activity, alcohol consumption, sexual health behavior, and smoking cessation included. From the included studies 10,747 participants were eligible. Culturally adapted IMI proved to be non-superior over active control conditions in short- (g = 0.10, [95% CI -0.19 to 0.40]) and long-term (g = 0.20, [95% CI -0.11 to 0.51]) in promoting health behavior. However, culturally adapted IMI for physical activity (k = 3, N = 296) compared to active controls yielded a beneficial effect in long-term (g = 0.48, [95%CI 0.25 to 0.71]). Adapting health promotion IMI to the cultural context of different cultural populations seems not yet to be recommendable given the substantial adaption efforts necessary and the mostly non-significant findings. However, these findings need to be seen as preliminary given the limited number of included trials with varying methodological rigor and the partly substantial between-trial heterogeneity pointing in the direction of potentially useful culturally adapted IMI which now need to be disentangled from the less promising approaches.PROSPERO registration number: 42020152939., (© 2022.

Purpose: To compare peripapillary choroidal vascularity index (CVI) parameters in pseudoexfoliation glaucoma (PEG), pseudoexfoliation (PEX) syndrome, and healthy controls., Methods: A total of 240 eyes of 240 patients were included in this cross-sectional prospective study, and the three groups consisted of (i) 80 eyes of 80 patients with PEG, (ii) 80 eyes of 80 patients with PEX syndrome, and (iii) 80 healthy control eyes. Peripapillary enhanced depth imaging optical coherence tomography images were binarized via standard protocols with the ImageJ software. CVI was analyzed in all sectors of the peripapillary region., Results: Peripapillary CVI was found to be significantly lower in the PEG group (61.6 ± 2.32) compared with the PEX group (64.7 ± 3.15) and the control group (67.5 ± 2.44) ( p < .001), and patients with PEX also had significantly lower values compared to controls ( p < .001). Peripapillary CVI values were significantly lower in the temporal, nasal, superotemporal, superonasal, inferotemporal and inferonasal sectors of the PEG group compared to both the PEX group and controls ( p < .001). Peripapillary CVI was also found to be lower in all sectors in the PEX group compared to controls ( p < .001). Global peripapillary choroidal thickness was significantly thinner in the PEG group than the PEX and control groups (133.37 ± 39.16, 154.36 ± 33.28 and 157.82 ± 36.77 μm, respectively, p < .001)., Conclusions: In the current study, it was shown that the presence of PEX caused a decrease in CVI value and this decrease was highest in patients with PEG. CVI may be a useful parameter to show vascular dysfunction in PEG and PEX syndrome.

Background and Aims: This study aimed to evaluate whether there is a difference in human papillomavirus (HPV), smear, and cervical biopsy results between patients with and without diabetes mellitus (DM)., Methods: Retrospectively, 136 patients with positive high risk (HR) HPV screening results with and without DM who underwent colposcopy between 2015 and 2019 were identified. The clinicopathological characteristics and HR HPV screening results were reported and analyzed. The results of the patients with and without DM were compared., Results: HPV 16 positivity, Atypical Squamous Cells of Undetermined Significance (ASCUS), and Cervical Intraepithelial Neoplasia 1 (CIN 1) in smear and biopsy results were higher in patients with DM than patients without DM., Conclusions: The higher HPV positivity in patients with diabetes may require reforming the frequency and method of cervical cancer screening to be applied to this patient group., Competing Interests: Declaration of competing interest The authors declared no conflict of interest., (Copyright © 2021 Diabetes India.

Gamification, or the intentional use of gaming elements in non-game contexts, has been touted as a promising tool to improve educational outcomes in online education, yet the evidence regarding why it might work and its effectiveness is inconclusive. One reason is that previous research has often included several gamification tools together, neglecting that each gamification tool can vary in effectiveness. In order to evaluate their relative impact, two frequently used gamification tools, badges (i.e., digital credentials given for achievements) and leaderboards (i.e., digital rankings based on performance), were compared for their effectiveness on the academic performance and motivation of students. Two experiments were conducted in two online undergraduate physics courses taught via a learning management system. In Experiment 1 (N = 102), badges and leaderboards were implemented in only one part of the course grading system (i.e., quizzes). In Experiment 2 (N = 88), all course grading system was gamified (i.e., quizzes and assignments). Four groups were created by random assignment of participants: badges-only, leaderboards-only, badges with leaderboards, and control (i.e., no badges, no leaderboards). Academic performance was measured by comparing quiz scores among groups in Experiment 1 and both quiz and assignment scores in Experiment 2. Participants filled out a self-report motivation survey about badges and leaderboards at the end of the study. Two experiments yielded similar results: badges and leaderboards did not affect participants' academic performance; however, most students approached them positively as motivational tools and wanted to see them in future online classes., Competing Interests: Conflict of interestThe authors have no conflicts of interest to declare that are relevant to the content of this article. , (© The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2022.)

In the study, a multi-purpose reverse logistics network has been designed to create effectual management of medical waste (MW) generated in 39 districts of Istanbul, a heavily populated city, during the COVID-19 pandemic as well as that to be generated in the next decade. With the model, the medical waste management system in Istanbul is analyzed during the pandemic and for the next 10 years. The model attempts to integrate economic, environmental, and social objectives within the sustainable development goals. It aims to maximize the number of personnel and government earnings for the estimated MW of a megacity while minimizing the total fixed cost and the cost of carbon emissions and transportation. The results indicated that the existing facilities are sufficient for the treatment and disposal of MW generated even under pandemic conditions. However, the capacity of the sterilization facility could be insufficient to treat the estimated amount of MW in the next decade. Opening a sterilization facility near the sanitary landfill in Komurcuoda with a total management cost of 62,450,332 €/year would be an optimum solution for Istanbul MW. In comparison to the single-purpose model results, the multi-purpose model resulted in approximately 42,000 € more in total cost. Sensitivity analyses show that the amount of MW has the most significant effect on the total cost. This simple model created an effective MW management proposal for Istanbul, which can be a model for megacities., Supplementary Information: The online version contains supplementary material available at 10.1007/s10669-022-09873-z., Competing Interests: Conflict of interestThe authors declare that they have no competing interests., (© The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2022, Springer Nature or its licensor holds exclusive rights to this article under a publishing agreement with the author(s) or other rightsholder(s); author self-archiving of the accepted manuscript version of this article is solely governed by the terms of such publishing agreement and applicable law.)

Objective: The objective of the study was to evaluate the concordance between colposcopic biopsy and loop electrosurgical excision procedure (LEEP) methods to diagnose cervical pre-invasive lesions and cervical cancer, and to calculate the low and high prediction rates of lesions for both methods., Methods: A total of 241 patients who underwent LEEP after colposcopic biopsy for different indications and also known cervical cytology and human papillomavirus test results were included in the study. Clinical variables such as age, gravida, parity, menopausal status, smoking, endocervical curettage results, and surgical margins were recorded., Results: The total concordance between colposcopic biopsy and LEEP was 41.9%. The rates of finding a more serious lesion than in colposcopic biopsy with LEEP (underestimation) for negative, Cervical Intraepithelial Neoplasia (CIN) 1, CIN 2, and CIN 3 were calculated as 100%, 12.8%, 14.8%, and 3.9%, respectively. Rates of finding a less serious lesion than detected in colposcopic biopsy with LEEP (overestimation) for CIN 1, CIN 2, and CIN 3, cervical carcinoma were calculated as 56.4%, 33.3%, 3.9%, and 0%, respectively. Underestimation was seen in a total of 28 patients, and overestimation was present in 113 patients. Parity was found to be the only associated factor that affected the final diagnosis for high-grade lesions in univariate logistic regression analysis (odds ratio=1.234, 95% confidence interval: 1.005-1.514)., Conclusion: Discrepancies between colposcopically directed punch biopsy and subsequent histopathologic LEEP findings are common. New methods to reduce the inconsistency between colposcopic biopsy and LEEP are necessary to prevent patients from being under or over treated., Competing Interests: Conflict of Interest: No conflict of interest was declared by the authors., (Copyright © by by Istanbul Provincial Directorate of Health - Available online at www.northclinist.com.)
