Geochemical characterization of changes in the chemical composition of river sediments under the continuous anthropogenic influence of Yerevan, Armenia.

The long-term study of the chemical composition of river sediments within urban areas and the establishment of baseline values of major and trace elements is an important task. Therefore, this study aims to provide a geochemical characterization of the sediments, establish a local geochemical baseline, unveil geochemical associations of elements, study the trend of changes in element pollution levels and the associated ecological risks. The results indicate that the change of the local physical characteristics across the river flow (canyon-flat relief surrounded by buildings-reservoir-flat relief under the influence of contamination sources) and locations of contamination sources conditioned the formation of positive extreme values detected for the majority of the studied elements. An analogous variation pattern of major and trace elements median values (2019-2023) was observed for Cr, V, Cu, Fe, Co, Zr Mn, Zn, K, Ba over 5 years representing the geochemical signature of the local geological composition (basalt, andesibasalts, andesite, tuff, K-feldspar). The pollution level and the ecological risk assessment showed that during the study period moderately and highly hazardous levels of multi-element pollution were detected in the southwestern part of the river located near the industrial enterprises. In the meantime, moderate (in 2020) and considerable (in 2021) ecological risk levels were observed at the site near the artificial reservoir. A hierarchical clustering combined with the geochemical ratio analysis reveals three groups of geochemical associations that have a natural (Fe, Mn, Co, V, Ti, Zr, K, Rb, Ba); anthropogenic (Cu, Zn, Pb, Mo) and mixed (Ca, Sr, Cr) origin. Moreover, the anthropogenic association shows affinity to Ca hence denominating the dominant role of carbonates in the fixation and coprecipitation of Cu2+, Pb2+, Mo2+, Zn2+ ions. The comparison of the baseline values of the studied elements with the upper continental crust values confirmed their applicability for differentiation of their origin.

A combined laparoscopic and vaginal approach with a novel method to reconstructing the uterine cervix in Herlyn-Werner-Wunderlich syndrome with cervical obstruction: A case report.

INTRODUCTION: Herlyn-Werner-Wunderlich syndrome (HWWS) is characterized by uterine didelphys, unilateral cervical obstruction, and ipsilateral renal defects. Owing to its rarity, no standard surgical approach exists. PRESENTATION OF CASE: An 11-year-old girl with severe dysmenorrhea had a duplicated uterus, a right cervical hemorrhagic cyst, and right ipsilateral kidney agenesis, indicative of HWWS. As transvaginal surgery was challenging, we turned to laparoscopic surgery for abdominal cavity inspection and surgical assistance. A longitudinal incision was made on the right uterus, followed by inserting a catheter tube fixed to an intrauterine device (IUD) into the right cervical canal from the anterior wall of the right uterine horn. Subsequently, the right external cervical os was inverted to prevent restenosis. Postoperatively, the hemorrhagic cyst at the right cervix disappeared. The patient had no symptom recurrence 24 months after the surgery. DISCUSSION: The preoperative diagnosis for female genital malformations is complicated, and transvaginal manipulation is often difficult in adolescent girls. Laparoscopy is a valuable tool for evaluating female genital malformations, allowing for a thorough diagnosis and safe surgical treatment. In cases of female genital malformation with cervical obstruction, as in this case, reconstruction of the uterine cervix is important to prevent restenosis after surgery. CONCLUSION: In female genital malformations, laparoscopy provides a comprehensive evaluation of the malformation, assisting in a precise diagnosis and safe surgical treatment. Insertion of the catheter tube with IUD into the uterus and reconstruction of the cervix contribute to preventing restenosis.

Maternal diseases and congenital anomalies of the kidney and urinary tract in offspring: a cohort study.

BACKGROUND: Congenital anomalies of the kidneys and urinary tract (CAKUT) are the most common cause of prenatally diagnosed developmental malformation. This study aimed to assess the relationship between maternal diseases and CAKUT in offspring. METHODS: This retrospective study enrolled all pregnant women registered from January 2020 to December 2022 at one medical center. Medical information on maternal noncommunicable diseases, including obesity, hypertension, diabetes mellitus, kidney disease, hyperthyroidism, hypothyroidism, psychiatric disease, epilepsy, cancer, and autoimmune disease was collected. Based on the records of ultrasound scanning during the third trimester, the diagnosis was classified as isolated urinary tract dilation (UTD) or kidney anomalies. Multivariate logistic regression was performed to establish models to predict antenatal CAKUT. RESULTS: Among the 19,656 pregnant women, perinatal ultrasound detected suspicious CAKUT in 114 (5.8/1000) fetuses, comprising 89 cases with isolated UTD and 25 cases with kidney anomalies. The risk of antenatal CAKUT was increased in the fetuses of mothers who experienced gestational diabetes, thyroid dysfunction, neuropsychiatric disease, anemia, ovarian and uterine disorders. A prediction model for isolated UTD was developed utilizing four confounding factors, namely gestational diabetes, gestational hypertension, maternal thyroid dysfunction, and hepatic disease. Similarly, a separate prediction model for kidney anomalies was established based on four distinct confounding factors, namely maternal thyroid dysfunction, gestational diabetes, disorders of ovarian/uterine, and kidney disease. CONCLUSIONS: Isolated UTD and kidney anomalies were associated with different maternal diseases. The results may inform the clinical management of pregnancy and highlight potential differences in the genesis of various subtypes of CAKUT.

True uterus didelphys in she-camel: a case report and review of literature.

Background: Uterus didelphys is a rare congenital anomaly of the female reproductive tract characterized by a divided uterine cervix and body. It occurs due to abnormal development of the paramesonephric (Müllerian) duct. Different forms of uterus didelphys have been reported in several animal species, including bovine, equine, ewe, goat, swine, and bitch. However, there is no previous report that has documented a completely divided female genital tract in she-camel. Moreover, there is a lack of literature regarding this anomaly in animals. Therefore, the present study reports, for the first time, a rare case of a completely divided female genital tract in a she-camel. In addition, the existing relevant literature on uterus didelphys in different animal species is reviewed. Case presentation: A female reproductive tract of she-camel, approximately 10 years old, with a history of previous successful pregnancy, was brought to the anatomy department following the slaughtering of the animal. Initial examination revealed a normal reproductive tract consisting of two ovaries, two fallopian tubes, a uterus, and a vagina. A closer examination revealed a completely divided vagina, with an external os opened into each part of the vagina, as well as a divided uterine body and cervix. Intrauterine infusion of saline through one external os confirmed complete separation of uterine body and cervix. Conclusion: To the authors' knowledge, this is the first reported case of a completely divided female genital tract in a she-camel. This review summarizes the previous reports about uterus didelphys in farm animals.

A Novel Case of Anomalous Origin of Left Vertebral Artery Associated With Left Subclavian Steal Syndrome.

The subclavian steal syndrome (SSS) is defined by the reversal of flow in the ipsilateral vertebral artery in the setting of subclavian artery stenosis proximal to its origin. Here, we describe a rare case of left SSS with significant left subclavian artery stenosis associated with anomalous origin of the left vertebral artery (LVA) directly from the aortic arch in a patient presenting with signs of vertebrobasilar insufficiency and resolution of symptoms following angioplasty. Through this case, the authors try to emphasize the importance and the correct technique of using Doppler ultrasonography, and the importance of invasive angiography in understanding the mechanism of subclavian steal in patients with anomalous LVA origin.

High comorbidity rates in congenital lobar emphysema and the effect on clinical presentation.

The presence of comorbidities (CM) in congenital lobar emphysema (CLE) has been previously described with varying rates. However, the clinical implication of CM on the clinical presentation and patient outcome in CLE is unclear. This was a retrospective cohort study between 2000 and 2022 in a single institution. The study included pediatric patients diagnosed with CLE. During the study period, 36 patients were identified with CLE. The presence of respiratory symptoms at diagnosis was documented in 69% (24/35) of the patients with 48% admitted to intensive care units. The presence of CM was documented in 14/36 (39%) of the patients, with cardiovascular anomalies as the most common (22%), followed by genitourinary anomalies (11%) and large airway anomalies (8%). When comparing the CM group (n = 14) vs the non-CM group (N = 22), there was no significant difference regarding gender, term birth, age of diagnosis, and the location of the lesion. The CM group had significantly higher rates of intensive care unit (ICU) admissions (75% vs 33%, p = 0.02), longer duration of admission (median 46 days vs 9, p = 0.02), and need for pre-operative non-invasive respiratory support (50% vs 5%, p = 0.002).Conclusion: The presence of CM in CLE was associated with a more severe presentation as reflected with significantly higher rates of ICU admissions, prolonged admissions, and higher need for non-invasive respiratory support. Screening for CM, mostly for cardiac anomalies, is recommended at time of CLE diagnosis. What is Known: • Congenital lobar emphysema (CLE) is a developmental lung anomaly generally associated with other comorbidities; however, their clinical implication on presentation is unclear • The prevalence of comorbidities in CLE was previously reported around 15-20%, with cardiovascular anomalies as the most common What is New: • Comorbidities are very common (39%) in CLE, and their presence is related to a more severe clinical presentation and need for respiratory support • Screening for comorbidities is recommended in CLE, specifically for cardiovascular and genitourinary anomalies.

Maternal and fetal outcomes of antiepileptic treatments during pregnancy: A retrospective study.

INTRODUCTION: Epilepsy is a disease that affects a significant proportion of the female population worldwide. The management of anti-seizure medications during pregnancy and the potential adverse outcomes to both the mother and fetus represent a significant challenge. This retrospective study aimed to evaluate the impact of anti-seizure medications during pregnancy by comparing maternal and fetal outcomes between pregnant women with and without epilepsy. METHODS: A total of 242 participants were analysed, including 112 with epilepsy and 130 healthy pregnant controls. Maternal age, medical history, seizure characteristics, use of anti-seizure medications, and pregnancy history were recorded. Maternal and fetal complications, delivery modes, and perinatal outcomes were evaluated. RESULTS: A total of 242 patients, including 112 (46.3 %) pregnant women with epilepsy and 130 (53.7 %) healthy pregnant women, were included in the study. Among pregnant patients with epilepsy, 4 (3.5 %) did not use anti-seizure medications, 79 (70.5 %) received monotherapy, and 29 (25.8 %) received polytherapy. The rates of pregnancy termination, spontaneous abortion, and maternal and fetal complications were significantly higher in pregnant women with epilepsy (p = 0.045, p = 0.045, p < 0.001, and p = 0.016, respectively). Folic acid use, planned pregnancy rate and postpartum breastfeeding rate were all statistically lower in pregnant women with epilepsy (p < 0.001, p < 0.001, p < 0.001, respectively). The rates of intensive care unit stay, infants with birth weight less than 2500 g, congenital malformations, and preterm births were significantly higher in babies born to pregnant women with epilepsy (p < 0.001, p = 0.047, p = 0.003, and p = 0.051, respectively). Gestational diabetes mellitus was observed in 4 (13.8 %) and congenital malformations in 4 (14.3 %) of the pregnant women with epilepsy who received polytherapy, and in both cases these rates were statistically higher than those of pregnant women with epilepsy who received monotherapy (p = 0.048 and p = 0.004, respectively). DISCUSSION: This study demonstrated that pregnancies among women affected by epilepsy have significantly higher rates of maternal and fetal complications, spontaneous abortions, and premature births. Polytherapy with anti-seizure medications is associated with an increased risk of gestational diabetes and congenital anomalies. Notably, folic acid use, planned pregnancy, and postpartum breastfeeding were less common in patients with epilepsy. The most commonly prescribed anti-seizure medications were levetiracetam and lamotrigine. Caesarean section is a common mode of delivery in pregnancies of mothers with epilepsy. CONCLUSION: These results suggest that epilepsy increases both maternal and fetal complications during pregnancy. Furthermore, the use of anti-seizure medications appears to have a significant impact on pregnancy outcomes. Our findings highlight the need for comprehensive management strategies and informed decision making to reduce risks and optimise maternal and fetal outcomes among women with epilepsy.

Prevalence and Patterns of Positional Dental Anomalies in First Permanent Molars: Insights from a Study in Oradea, Romania.

Tooth position anomalies, influenced by both genetic and environmental factors, can significantly impact oral health and play a critical role in establishing proper occlusion. The aim of this study was to identify the most prevalent tooth position anomalies in first permanent molars among Romanian patients and to evaluate additional variables as well. This retrospective study utilized digital study models to identify all existing tooth position anomalies. The study included patients aged 12 to 40 years with complete permanent dentition. Axial changes (buccal tilting, oral tilting, mesial tilting, and distal tilting) as well as rotational changes (mesio-buccal rotation and disto-buccal rotation) were investigated. After applying the exclusion criteria, 103 patients remained in the study. Our findings revealed a notable prevalence of positional anomalies, with disto-buccal rotations being most common in upper molars (tooth 1.6-22.3%, tooth 2.6-31.1%) and oral tilting predominating in lower molars (tooth 3.6-6.8%, tooth 4.6-14.6%). Interestingly, neither gender nor malocclusion type significantly influenced the occurrence of tooth position anomalies. Symmetrical patterns in positional changes were observed, with patients having tooth position anomalies at 1.6 significantly more frequently associated with anomalies at 2.6. Similarly, anomalies at 3.6 were significantly more frequently associated with anomalies at 4.6. Additionally, for molars 2.6 and 3.6 on the left side, the differences were statistically significant, with patients having anomalies at 2.6 significantly more frequently associated with anomalies at 3.6. This pattern was not observed for the molars situated on the right side of the dental arches. While this study provides insights into positional anomalies in first permanent molars among the Romanian population, its retrospective design and focus on a specific demographic may limit generalizability. In conclusion, the study underscores the significant prevalence of positional anomalies in first permanent molars among adolescents and adults in Oradea, Romania. Early detection and targeted interventions are crucial to address these anomalies and improve orthodontic outcomes. Comprehensive assessment and treatment planning are essential to achieve optimal dental harmony and function. Further research is needed to elucidate the underlying factors contributing to these positional changes and their long-term impact on oral health and occlusal stability.

Bow hunter's syndrome due to an anomalous right vertebral artery origin and contralateral absence: a case report and literature review.

BACKGROUND: Bow Hunter's syndrome (BHS), also known as rotational vertebral artery occlusion (RVAO), is a rare condition characterized by dynamic vertebrobasilar insufficiency due to position-dependent occlusion of the vertebral artery (VA). In the existing literature, most cases of BHS are attributed to osteophytic compression originating from the occipital condyle or within the transverse foramen, often accompanied by anatomical abnormalities of the VA. However, cases presenting solely with VA anomalies in the absence of any cervical vertebral structural abnormality are rare. This case report presents a unique instance of BHS in a 56-year-old male, attributed to the anomalous origin of the right VA and the absence of the left VA, without cervical structural abnormalities. CASE PRESENTATION: The patient exhibited symptoms like episodic dizziness and vertigo, which were exacerbated by rightward head rotation and alleviated upon returning to a neutral position. Diagnostic evaluation, including digital subtraction angiography, revealed that the right VA originated from the right common carotid artery and compression-induced stenosis of the right VA during head rotation. Conservative management, including avoidance of certain head movements and anti-arteriosclerosis medication, led to symptom resolution over a two-year follow-up period. CONCLUSIONS: This report contributes to the understanding of BHS by highlighting a rare vascular anomaly presentation and incorporates a review of 14 similar case reports in the literature describing that an anatomical abnormality of the VA is mainly responsible for the pathology of BHS in the absence of cervical vertebral anomalies, thus emphasizing the need for careful diagnostic and management strategies.

Coronary Artery Anomalies: A Computed Tomography Angiography Pictorial Review.

Coronary arteries have a wide range of anatomical variability, and their spectrum ranges from asymptomatic cases to those predisposed to hemodynamic compromise or even sudden cardiac death. This paper aims to review the classification of coronary artery anomalies (CAAs) and illustrate their imaging characteristics by highlighting the important role of CT coronary angiography. Some of the coronary anomalies usually met in current practice are the high origin coronary artery, multiple ostia, aberrant origin from the opposite/non-coronary Valsalva sinus, single coronary artery, ALCAPA syndrome, duplications of the left anterior descending artery, coronary fistulas, and extracardiac terminations. CT coronary angiography is a non-invasive diagnostic modality for CAAs. The complex anatomy of these anomalies can be accurately described by employing 3D reconstructions and post-processing techniques. Knowledge of the imaging characteristics and potential functional impact of these anomalies is essential for accurate diagnosis and therapeutic planning of patients.

Immunoexpression Pattern of Autophagy-Related Proteins in Human Congenital Anomalies of the Kidney and Urinary Tract.

The purpose of this study was to evaluate the spatiotemporal immunoexpression pattern of microtubule-associated protein 1 light chain 3 beta (LC3B), glucose-regulated protein 78 (GRP78), heat shock protein 70 (HSP70), and lysosomal-associated membrane protein 2A (LAMP2A) in normal human fetal kidney development (CTRL) and kidneys affected with congenital anomalies of the kidney and urinary tract (CAKUT). Human fetal kidneys (control, horseshoe, dysplastic, duplex, and hypoplastic) from the 18th to the 38th developmental week underwent epifluorescence microscopy analysis after being stained with antibodies. Immunoreactivity was quantified in various kidney structures, and expression dynamics were examined using linear and nonlinear regression modeling. The punctate expression of LC3B was observed mainly in tubules and glomerular cells, with dysplastic kidneys displaying distinct staining patterns. In the control group's glomeruli, LAMP2A showed a sporadic, punctate signal; in contrast to other phenotypes, duplex kidneys showed significantly stronger expression in convoluted tubules. GRP78 had a weaker expression in CAKUT kidneys, especially hypoplastic ones, while normal kidneys exhibited punctate staining of convoluted tubules and glomeruli. HSP70 staining varied among phenotypes, with dysplastic and hypoplastic kidneys exhibiting stronger staining compared to controls. Expression dynamics varied among observed autophagy markers and phenotypes, indicating their potential roles in normal and dysfunctional kidney development.

The role of primary care in rare disorders: A qualitative study of parents and patients managing complex vascular anomalies.

Background: Patients with complex rare disorders often require the care of multiple specialists. Effective coordination between primary and specialty care is needed to ensure patients receive high-quality care. Previous research has documented the importance of primary care clinicians providing referrals to specialty care and the importance of specialists in helping patients reach a diagnosis. However, little is known about primary care clinicians' roles in the ongoing care of patients with rare disorders. In the current study, we explored the role of primary care clinicians in the care of rare and complex vascular anomalies. Materials and Methods: Data were collected using semi-structured qualitative interviews with 34 parents and 25 adult patients recruited from advocacy groups for patients with complex vascular anomalies participated. We asked participants about their diagnosis, care experiences, and communication with clinicians. We used thematic analysis to identify themes illustrating the roles of primary care clinicians. Results: PCC roles were characterized by four behaviors. Supporting behaviors included learning more about vascular anomalies and asking participants about the care they received from specialists. Facilitating included providing referrals, ordering tests, and engaging in problem-solving. Interfering included failing to provide referrals or help participants coordinate care, ordering incorrect tests, or making inappropriate recommendations. Disregarding included focusing narrowly on primary care needs and not showing concern about the vascular anomaly. Conclusions: The results reveal opportunities to improve primary care for patients with vascular anomalies. Disregarding and interfering behaviors furthered the division between primary and specialty care for patients with vascular anomalies and prevented patients from receiving comprehensive primary care. Supporting and facilitating behaviors convey genuine interest in the care of the vascular anomaly and a commitment to helping the patient and parent.

Developmental Causes of Focal Segmental Glomerulosclerosis.

Background: Focal segmental glomerulosclerosis (FSGS) is a histological pattern of glomerular damage that includes idiopathic conditions as well as genetic and non-genetic forms. Among these various etiologies, different phenotypes within the spectrum of congenital anomalies of the kidney and urinary tract (CAKUT) have been associated with FSGS. Summary: Until recently, the main pathomechanism of how congenital kidney and urinary tract defects lead to FSGS was attributed to a reduced number of nephrons, resulting in biomechanical stress on the remaining glomeruli, detachment of podocytes, and subsequent inability to maintain normal glomerular architecture. The discovery of deleterious single-nucleotide variants in PAX2, a transcription factor crucial in normal kidney development and a known cause of papillorenal syndrome, in individuals with adult-onset FSGS without congenital kidney defects has shed new light on developmental defects that become evident during podocyte injury. Key Message: In this mini-review, we challenge the assumption that FSGS in CAKUT is caused by glomerular hyperfiltration alone and hypothesize a multifactorial pathogenesis that includes overlapping cellular mechanisms that are activated in both damaged podocytes as well as nephron progenitor cells.

A Rare Case of Right Fourth Branchial Fistula: A Diagnostic Challenge.

Fourth branchial anomalies are extremely rare and are often misdiagnosed. A recurrent history of anterior neck discharges or infections since childhood should raise a high clinical suspicion of branchial fistula and necessitate a thorough clinical, endoscopic, and radiological evaluation. We report a rare case of right-sided fourth branchial fistula in a middle-aged lady who was referred to us for recurrent right neck infections since childhood and had received multiple courses of antibiotics and drainage of abscesses. Despite previous negative barium swallow and fistulogram results, the diagnosis of the branchial fistula was made clinically with the spillage of methylene blue dye into the apex of the right pyriform sinus from flexible nasopharyngolaryngoscopy in the clinic after the injection of dye through the fistula opening at the neck. Finally, another barium swallow study and computed tomography scan were conducted, revealing the fistula tract. Complete surgical excision of the fistula tract was then performed with no evidence of recurrence after six months of follow-up.

The Role of Midwives in US Perinatal Palliative Care: A Scoping Review.

INTRODUCTION: Perinatal palliative care (PPC) is a rapidly growing and essential reproductive health care option for pregnant persons with a diagnosed life-limiting fetal condition who continue their pregnancy. The provision of PPC is within the scope of basic midwifery competencies, and midwives are well-positioned to make unique and valuable contributions to interprofessional PPC teams. However, little is known about midwives' past or current involvement in PPC in the United States. METHODS: This scoping review of the literature investigated what is known about the role of midwives in PPC in the United States. Multiple databases of published literature were used for this review: PubMed, CINAHL, Embase, Web of Science, ProQuest, Google Scholar, and relevant citations from identified studies. All types of English language publications addressing midwives' involvement in PPC in the United States were included, without any limitations on publication date. RESULTS: The role and contributions of midwives in PPC is not well represented in existing literature. Of the 259 results identified, 7 publications met criteria for inclusion. These included 5 case reports, one quantitative research article, and one conference abstract. Midwives are involved in PPC through the provision of direct clinical care (including antepartum, intrapartum, postpartum, neonatal, bereavement, postmortem, and follow-up care) and care planning and coordination as part of an interprofessional team. DISCUSSION: Despite midwives being uniquely positioned to provide holistic, family-centered, and person-centered care in situations of pregnancy with life-limiting fetal conditions, there is limited literature about their involvement in PPC in the United States. PPC should be incorporated into midwifery education and training programs. Midwives should play a central role in shaping future research and policies to ensure the accessibility and quality of PPC.

Exposure to golimumab during pregnancy: Results from the Company's global safety database.

Data on the use of golimumab (GLM) during pregnancy are limited. This study evaluated pregnancy outcomes in women treated with GLM during pregnancy. Cumulative data on GLM-exposed pregnancies from the Company's global safety database (GSD) are summarized. Cases were medically confirmed maternal exposures to GLM during pregnancy or within 3 months prior to conception with a reported pregnancy outcome. Pregnancy outcomes (e.g., live births) and congenital anomalies in prospectively reported cases (i.e., pregnancy outcome not known when first reported to the company) are presented in a descriptive manner. As of May 31, 2022, 261 prospectively reported pregnancies exposed to GLM were reported in the GSD: 214 (82.0%) live births (including six sets of twins), 31 (11.9%) spontaneous abortions (including one set of twins), 13 (5.0%) induced/elective abortions, 2 (0.8%) reported intrauterine death/still birth, and 1 (0.4%) fetal adverse event in an ongoing pregnancy. The majority of pregnancies had exposure to GLM at least in the first trimester of pregnancy. In total, seven congenital anomalies (7/261; 2.7%) were reported. Of these seven congenital anomalies, five were considered major according to EUROCAT classification version 1.4. Among the five prospectively reported congenital anomalies noted in live births (5/214; 2.3%), four were classified as major (4/214; 1.8%). The rates of adverse pregnancy outcomes and major congenital anomalies in prospectively reported pregnancy cases with exposure to GLM in the Company's GSD were consistent with published background rates for the general population.

Initial trial of three­lead wearable electrocardiogram monitoring in a full marathon.

Sudden cardiac arrest during exercise can occur without prior warning signs at rest, highlighting the importance of monitoring for its prevention. To detect the signs of ischemic heart disease, including coronary artery anomalies, ST changes must be detected using three­lead electrocardiograms (ECGs) corresponding to each region of the three coronary artery branches. We conducted ECG monitoring of five runners during a marathon using a wearable three­lead ECG device (e-skin ECG; Xenoma Inc., Tokyo, Japan). Data without noise or artifacts were successfully collected for one of five runners during the entire marathon. Within the initial hour of the marathon, poor electrode adhesion to the skin hindered the data collection for the remaining four runners, which resulted in significantly decreased acquisition rate compared with the first hour (86.7 ±â€¯13.4 % to 37.3 ±â€¯36.9 %, p = 0.028). Couplets of premature ventricular contractions with clear ECG waveforms in the three leads were detected in one runner during the marathon. Further device improvements are necessary to enable marathon runners to obtain ECGs efficiently without affecting their performance. This study also demonstrated the potential applications of three­lead wearable ECG monitoring for other short-duration sports and remote home-based cardiac rehabilitation. Learning objective: This is an initial trial of a three­lead wearable electrocardiogram (ECG) monitoring device during a full marathon. ECG data were obtained with low noise and artifacts during the first hour of the marathon; however, the data acquisition rate decreased in the middle and late stages owing to poor electrode adhesion. This study demonstrated the possibility of applying wearable ECG monitoring during short-term exercise and cardiac rehabilitation to detect warning signs and prevent sudden cardiac arrest.

3Dimensional sonography for the diagnosis of congenital uterine anomalies in women with eccentric pregnancy implantation: a novel approach.

PURPOSE: The eccentric implantation of pregnancies in the upper lateral aspect of the uterine cavity is poorly defined clinically. The aim of the current study was to investigate whether differentiating between uterine anomalies that can lead to cavitary distortion has implications for the management of these pregnancies. METHODS: Eight cases of first-trimester eccentric pregnancy implantation within the endometrial cavity (study group) were retrospectively identified. For each woman in the study group, 10 women identified as having a first-trimester concentric pregnancy implantation during the first-trimester US examination were retrieved from our database (control group). After delivery or pregnancy demise, the presence of uterine anomalies was assessed by a 3D-US examination in all patients. RESULTS: In the study group patients, an increased incidence of uterine anomalies (50.0% vs. 8.8%, p = 0.007) was found, compared to the controls. In the study group, the eccentric location persisted in half of the pregnancies (n = 4; 50%), whereas the other half migrated to a more centric location within the endometrial cavity (n = 4; 50%). The follow-up examination showed that all the early pregnancy demises occurred in cases where the pregnancy persisted at the eccentric location. Uterine malformations were also detected in all these cases. CONCLUSION: The data point to a significantly higher incidence of uterine anomalies in patients diagnosed with eccentric pregnancy implantation within the endometrial cavity. These results advocate for the value of differentiating between eccentric pregnancies in non-anomalous versus anomalous uteri.

The role of coronary CT angiography in athletes.

The sudden death of a young or high-level athlete or adolescent during recreational sports is one of the events with the greatest impact on public opinion in modern society. Sudden cardiac death (SCD) is the principal medical cause of death in athletes and can be the first and last clinical presentation of underlying disease. To prevent such episodes, pre-participation screening has been introduced in many countries to guarantee cardiovascular safety during sports and has become a common target among medical sports/governing organizations. Different cardiac conditions may cause SCD, with incidence depending on definition, evaluation methods, and studied populations, and a prevalence and etiology changing according to the age of athletes, with CAD most frequent in master athletes, while coronary anomalies and non-ischemic causes prevalent in young. To detect silent underlying causes early would be of considerable clinical value. This review summarizes the pre-participation screening in athletes, the specialist agonistic suitability visit performed in Italy, the anatomical characteristics of malignant coronary anomalies, and finally, the role of coronary CT angiography in such arena. In particular, the anatomical conditions suggesting potential disqualification from sport, the post-treatment follow-up to reintegrate young athletes, the diagnostic workflow to rule-out CAD in master athletes, and their clinical management are analyzed.
