BackgroundPrimary dysmenorrhea is a common gynecological problem characterized by recurrent, periodical, and cramping pain in the lower abdomen that occurs before or during menstruation, usually without pelvic disease. Its magnitude has not been well studied; some of the associated factors are inconclusive. Therefore, the goal of this study was to fill gaps on the magnitude, and associated factors of primary dysmenorrhea among female high school students in Nekemte town.ObjectivesTo assess the magnitude of primary dysmenorrhea, its associated factors among high school students in Nekemte town, East Wallaga, Western Oromia, Ethiopia, 2023.MethodsAn institutional-based cross-sectional study was conducted among high school students in Nekemte town from June 05 to 19, 2023. The calculated total sample size was 534, and data were collected from four governmental high schools and one private high school that were selected by multistage stratified sampling. The collected data were entered into Epi Info version 3.1 and analyzed using SPSS version 25. Binary and multivariable logistic regressions were used to find associations between dependent and independent variables.ResultsThe magnitude of primary dysmenorrhea was 68.4% (95% CI = 64.3%, 72.0%). Anxiety (AOR = 2.41, 95% CI = 1.31, 4.43), family history of primary dysmenorrhea (AOR = 4.64, 95% CI = 2.74, 7.86), sexual intercourse (AOR = 0.34, 95% CI = 0.21, 0.55), drinking tea &lt;4 cups per day (AOR = 0.38, 95% CI = 0.22, 0.60), and physical activity (AOR = 0.06, 95% CI = 0.03, 0.11) were factors associated with primary dysmenorrhea.ConclusionThe magnitude of primary dysmenorrhea was high among high school students in the study area. Sexual intercourse, physical activity, drinking tea, anxiety, and family history of primary dysmenorrhea were significantly associated with primary dysmenorrhea.

IntroductionIn individuals with chronic post-stroke hemiparesis, slow walking speed is a significant concern related to inadequate propulsion of the paretic limb. However, an overlooked factor is this population's altered morphology of the Achilles tendon, which may compromise the propulsive forces by the paretic limb. This study aimed to explore changes in Achilles tendon morphology, including gross thickness and intra-tendinous collagen fiber bundle organization, following stroke-induced brain lesions.MethodsFifteen individuals with chronic post-stroke hemiparesis (at least 6 months post-stroke) and 19 neurologically intact controls participated. Ultrasound imaging was used to evaluate Achilles tendon thickness and collagen organization in the paretic and non-paretic limbs of post-stroke participants, as well as in the right limb (control limb) of the neurologically intact control group.Results and discussionCompared to control individuals, the paretic limb in individuals post-stroke showed increased tendon thickness at the Achilles tendon insertion and 2 cm above it. The collagen fiber bundle at the Achilles tendon insertion of the paretic limb showed reduced organization compared to that in the control limb. Individuals post-stroke also exhibited slower walking speed, and increased plantarflexor muscle tone in the paretic limb compared to controls. In conclusion, individuals with chronic post-stroke hemiparesis demonstrated tendon thickening and collagen disorganization in the paretic limb, particularly at the insertion site of the Achilles tendon, likely due to an abnormal loading environment influenced by increased plantarflexor muscle tone, muscle co-activation, and muscle disuse and atrophy. These changes may increase tendon compliance, impair force transmission and propulsion, and contribute to slower walking speed. Addressing Achilles tendon integrity should be incorporated as a component of strategies to improve neuromuscular control in this population.

IntroductionHydroponic cultivation systems using desalinated groundwater may play pivotal role in reducing freshwater consumption for irrigation. However, reliance on desalination remains unsustainable due to its high cost, energy demand, and the serious environmental impacts of its brine byproducts. Producing a biofertilizer that enables groundwater irrigation in hydroponics by enhancing plant halotolerance and resistance to salt stress offers a promising solution to address freshwater scarcity and low soil quality in arid and semi-arid regions, such as the Arabian Gulf.MethodsThis study investigates the potential of Bacillus spizizenii FMH45 in field experiment to enhance tomato plant production under greenhouse cultivation in hydroponics using directly groundwater for irrigation without desalination.Results and discussionResults demonstrated that the FMH45-based biofertilizer (HB45) significantly improved plant physiological parameters under greenhouse conditions. These improvements included a notable increase in shoot elongation (&gt;13%), enhanced SPAD index values (&gt;8%), and significant rises in flower and fruit counts (≃ 11% and 22%, respectively). B. spizizenii HB45 showed significant potential to increase bacterial densities by over 100-fold in various plant organs under saline irrigation and prevent salt infiltration into internal plant tissues. Furthermore, HB45-treatment enhanced the plant oxidative stress response as evidenced by stable catalase activity, an approximately 50% reduction in lipid peroxidation markers such as malondialdehyde (MDA), and a 35% decrease in reactive oxygen species (ROS), including hydrogen peroxide (H2O2). These findings demonstrate that B. spizizenii FMH45 holds significant potential for the development of effective biofertilizers capable of mitigating salt stress while boosting crop productivity. This approach offers a sustainable alternative to desalination-dependent hydroponics, particularly for arid and semi-arid regions, including Qatar.

BackgroundDespite numerous operative and non-operative treatment modalities, patients with glioblastoma (GBM) have a dismal prognosis. Identifying predictors of survival and recurrence is an essential strategy for guiding treatment decisions, and existing literature demonstrates associations between hematologic data and clinical outcomes in cancer patients. As such, we provide a novel analysis that examines associations between preoperative hematologic data and postoperative outcomes following GBM resection.MethodsWe performed a retrospective analysis of patients who underwent GBM resection from January 2016 to December 2020. Standard demographic and clinical variables were collected, including pre-operative complete blood count (CBC), and inferential analyses were performed to analyze associations between CBC parameters and postoperative outcomes.ResultsOne hundred and eighty nine (189) patients met inclusion criteria, with a mean age of 60.7 years. On multivariate regression analysis, controlling for age, gender, and performance status, we observed trends suggesting anemic patients may have longer lengths of stay (t statistic = 3.23, p = 0.0015) and higher rates of discharge to inpatient facilities [OR 3.01 (1.09–8.13), p = 0.029], though these associations did not reach statistical significance after correction for multiple comparisons (Bonferroni-corrected significance threshold p &lt; 0.01).ConclusionPreoperative anemia may be a useful pre-operative predictor of postsurgical GBM outcomes. Further study is required to determine whether pre-operative hemoglobin optimization can improve postoperative clinical outcomes, and whether other hematologic and inflammatory markers are predictive of postoperative recovery and functional status.

Published: January 2025

IntroductionHemorrhoidal artery embolization, also known as Emborrhoid, has emerged in recent years as a minimally invasive treatment option for patients with recurrent and unresponsive to medical therapies hemorrhoidal bleeding symptoms. We present here an overview of the profile of rectal artery embolization based on the most relevant and recent literature.MethodsA comprehensive review of literature on Hemorrhoidal artery embolization, was conducted on PubMed–Medline. The most relevant literature was summarized narratively.ResultsCurrent literature confirms the feasibility, efficacy and safety of rectal artery embolization for bleeding hemorrhoids. To date, the results of nearly 250 patients who have undergone hemorrhoid embolization have been published in several studies. All these authors have reported high immediate technical success, with also high clinical success, ranging from 63% to 94%, without major complications. Because of its beneficial safety profile, rectal artery embolization represents an attractive option for selected patients. In case of recurrence of bleeding it is possible to consider repeating the embolization procedure. Treatment failure may be due to the presence of anatomical variants such as dominant middle rectal arteries, which can be investigated and treated in the second session if necessary.ConclusionRectal artery embolization represents a valuable addition to the therapeutic armamentarium of bleeding hemorrhoidal disease, if patients are selected appropriately.

Published: January 2025

BackgroundPrepancreatic postduodenal portal vein (PPPV) is a rare anatomic variant where the portal vein (PV) runs anterior to the pancreas and posterior to the duodenum. Only 20 cases of PPPV, all in adults, have been reported in literature. We report the first case of PPPV in a pediatric patient discovered intraoperatively during total pancreatectomy with islet autotransplantation (TPIAT) and the third known case in which the PPPV could be isolated intraoperatively.CaseA 10-year-old girl with debilitating acute recurrent pancreatitis requiring daily pain medication was admitted for elective TPIAT operation. Genetic workup for hereditary causes of pancreatitis was negative. Preoperative magnetic resonance cholangiopancreatography did not identify an abnormal course of the PV. During operation, dissection of tissues anteriorly overlying the pancreas revealed the variant PV anatomy. The PV was adherent to the anterior neck of the pancreas and coursed cranially posterior to the duodenum. Although prior reports have described PPPVs as thin-walled and fragile, the morphology and caliber of the PPPV appeared normal in our patient. The pancreas was adherent to and coursed between the PV and the superior mesenteric artery. The pancreas was meticulously dissected off the vessels and resected. The PPPV was successfully isolated and preserved for islet infusion later in the procedure. After isolation, 2/3 of islets were infused into the PV, and the remaining 1/3 were placed within the peritoneum due to persistently elevated portal venous pressures. There were no complications during the case, and the patient recovered as expected after operation.ConclusionOur case highlights the first reported case of PPPV in a pediatric patient and one of the three instances wherein it could be safely isolated intraoperatively. Recognition of such anatomic variations is crucial for the safety of operations such as TPIAT that include extensive vascular dissection in chronically scarred operative fields.

AimsThis study compared the hemostatic effects and complications of oxidized regenerated cellulose (ORC) and topical TXA in total knee arthroplasty (TKA), thus providing a reference for the use of ORC as an alternative hemostatic agent to TXA in TKA.MethodsA total of 105 patients were included in this study and randomized into blank control, ORC, and TXA groups. The primary outcomes were total blood loss, hemoglobin drop (Hb drop), transfusion rates, and incidence of thrombosis. The secondary outcomes included operation time, tourniquet duration, coagulation parameters, inflammation markers, and complication rates.ResultsTotal blood loss was 1,002.47 ± 308.58 ml and 964.68 ± 273.00 ml in the ORC and TXA groups, respectively, both significantly lower than that in the blank control group (1,168.94 ± 405.04 ml) (P1 = 0.043 and P2 = 0.014, respectively). Hb Drop was statistically insignificantly different between the ORC (36.03 ± 12.17 g/L) and TXA (34.32 ± 10.19 g/L) groups (P = 0.555). There was no statistically significant difference in transfusion rate, operation time, tourniquet duration, coagulation parameters, inflammation markers, and complication rates among the three groups.ConclusionIn conclusion, our prospective randomized controlled trial (RCT) highlights that, oxidized regenerated cellulose (ORC) can reduce postoperative invisible blood loss in total knee arthroplasty and achieve a hemostatic effect similar to topical tranexamic acid (TXA). This provides a safe and effective hemostatic option for patients with severe underlying diseases or contraindications to tranexamic acid.Clinical Trial registrationhttps://www.chictr.org.cn/bin/project/edit?pid=186370, identifier (ChiCTR2200066633).

ObjectiveThis study aimed to evaluate the medium-term outcome following spinal cord decompression and instrumented fixation of single-level congenital thoracolumbar vertebral malformations, characterized by combined failures of segmentation and formation, causing thoracolumbar myelopathy in three large-breed dogs.Study designThis was a retrospective clinical study.AnimalsThe animals involved in the study were three large-breed dogs.MethodsElectronic patient records were retrospectively reviewed for adult large-breed dogs (&gt;1 year) (&gt;25 kg) with thoracolumbar myelopathy and a radiologic diagnosis of spinal cord compression associated with thoracolumbar vertebral malformation. The examination, diagnostic imaging, surgical management, and outcomes are described. The medium-term outcome was determined based on the neurological examination and follow-up imaging studies conducted up to 12 months post-operation.ResultsThree large-breed dogs were identified, presenting with progressive, non-painful T3–L3 spinal cord segment disease. Diagnosis was made using MRI and CT, which revealed single-level complex congenital vertebral malformation with combined failures of segmentation and formation in the T8–L1 region. Surgical management consisted of ventral cord decompression by bilateral mini-hemilaminectomy and partial corpectomy and vertebral fixation. Temporary postoperative neurological deterioration was observed in two cases. Follow-up was conducted at 6 weeks (examination) and 3 (examination), 6, and 12 months (examination and CT) postoperatively, and improved neurological function was confirmed, with all cases being ambulatory with persistent, mild paraparesis.ConclusionThis retrospective study demonstrates the successful medium-term outcome following surgical management of complex thoracolumbar vertebral malformations in large-breed dogs.

Published: January 2025

Mixed-metal nickel-iron, NixFe materials draw attention as affordable earth-abundant electrocatalysts for the oxygen evolution reaction (OER). Here, nickel and mixed-metal nickel-iron metal–organic framework (MOF) composites with the carbon materials ketjenblack (KB) or carbon nanotubes (CNT) were synthesized in situ in a one-pot solvothermal reaction. As a direct comparison to these in situ synthesized composites, the neat MOFs were postsynthetically mixed by grinding with KB or CNT, to generate physical mixture composites. The in situ and postsynthetic MOF/carbon samples were comparatively tested as (pre-)catalysts for the OER, and most of them outperformed the RuO2 benchmark. Depending on the carbon material and metal ratio, the in situ or postsynthetic composites performed better, showing that the method to generate the composite can influence the OER activity. The best material Ni5Fe-CNT was synthesized in situ and achieved an overpotential (η) of 301 mV (RuO2 η = 354 mV), a Tafel slope (b) of 58 mV/dec (RuO2 b = 91 mV/dec), a charge transfer resistance (Rct) of 7 Ω (RuO2 Rct = 39 Ω), and a faradaic efficiency (FE) of 95% (RuO2 FE = 91%). Structural changes in the materials could be seen through a stability test in the alkaline electrolyte, and chronopotentiometry over 12 h showed that the derived electrocatalysts and RuO2 have good stability.

Augmentation mammaplasty with implants is the second most common plastic surgery performed in Brazil and the most common in the United States. The present research is a retrospective study based on a review of medical records and, subsequently, on the occurrence of intervention through interviews and the application of a results satisfaction questionnaire, the BREAST-Q questionnaire, and a breast augmentation module applied after the first postoperative year. Fifty-four female patients who underwent augmentation mammaplasty with the inclusion of breast implants with a polyurethane and nanotextured surface were included. Objective: To evaluate the satisfaction and quality of life of patients undergoing augmentation mammaplasty with implants with a nanotextured and polyurethane surface. Method: A retrospective study was conducted with 54 women with hypomastia who underwent augmentation mammaplasty with polyurethane surface and nanotextured retroglandular implants. The participants were evaluated postoperatively with a Brazilian version of the BREAST-Q breast augmentation module regarding their quality of life and satisfaction with the outcome of the procedure. Results: In one analysis, the degree of satisfaction of two groups was compared according to each of the questions and for each questionnaire. Conclusions: The use of the BREAST-Q questionnaire as an evaluation tool allowed us to analyze the differences in patient perceptions between two groups of implants and produced reliable and reproducible results on the effectiveness of breast surgery. Overall, the results indicated greater satisfaction among the patients in the polyurethane group than those in the nanotextured group.

Abstract
To advance the practical application of retinal prostheses with high spatial resolution through parallel stimulation, we developed a dynamic power supply voltage control system designed to enable stable constant-current stimulation in vivo, regardless of the number of active stimulation points. The proposed retinal prosthesis integrates a CMOS chip, containing current sources and electrode selection circuits, into a stimulation electrode array implanted in the eye. This configuration facilitates individual control of over 1000 electrodes with minimal wiring. In this study, we designed and integrated a power supply voltage monitoring circuit into the chip, allowing for real-time control of an external power generation circuit through feedback from the intraocular monitoring circuit. We demonstrated that the proposed system rapidly restored the power supply voltage when a voltage drop of 1 V occurred in the Pt wiring between the power supply unit and the chip, even while delivering a stimulation current of 1.5 mA in parallel across more than 100 electrodes.

Abstract
This paper presents an investigation of the inclusive behavior of B/P/As atoms within Arai tetra-interstitial (I

4
), a self-interstitial aggregate, inside implanted Si wafers during device processing using ab initio calculations. The results reveal the relative stabilities of B/P/As atoms in Arai tetra-interstitials and demonstrate that the gap levels of the Arai tetra-interstitials drastically change upon replacing Si atoms with these dopant atoms, particularly in the case of B. These levels significantly affect the p–n junction leakage currents of imaging devices.
