Bulk photovoltaic effect and high mobility in the polar 2D semiconductor SnP2Se6.

The growth of layered 2D compounds is a key ingredient in finding new phenomena in quantum materials, optoelectronics, and energy conversion. Here, we report SnP2Se6, a van der Waals chiral (R3 space group) semiconductor with an indirect bandgap of 1.36 to 1.41 electron volts. Exfoliated SnP2Se6 flakes are integrated into high-performance field-effect transistors with electron mobilities >100 cm2/Vs and on/off ratios >106 at room temperature. Upon excitation at a wavelength of 515.6 nanometer, SnP2Se6 phototransistors show high gain (>4 × 104) at low intensity (≈10-6 W/cm2) and fast photoresponse (< 5 microsecond) with concurrent gain of ≈52.9 at high intensity (≈56.6 mW/cm2) at a gate voltage of 60 V across 300-nm-thick SiO2 dielectric layer. The combination of high carrier mobility and the non-centrosymmetric crystal structure results in a strong intrinsic bulk photovoltaic effect; under local excitation at normal incidence at 532 nm, short circuit currents exceed 8 mA/cm2 at 20.6 W/cm2.

2D MXene electrochemical transistors.

The solid-state field-effect transistor, FET, and its theories were paramount in the discovery and studies of graphene. In the past two decades another transistor based on conducting polymers, called organic electrochemical transistor (ECT), has been developed and largely studied. The main difference between organic ECTs and FETs is the mode and extent of channel doping; while in FETs the channel only has surface doping through dipoles, the mixed ionic-electronic conductivity of the channel material in organic ECTs enables bulk electrochemical doping. As a result, organic ECTs maximize conductance modulation at the expense of speed. To date ECTs have been based on conducting polymers, but here we show that MXenes, a class of 2D materials beyond graphene, enable the realization of electrochemical transistors (ECTs). We show that the formulas for organic ECTs can be applied to these 2D ECTs and used to extract parameters like mobility. These MXene ECTs have high transconductance values but low on-off ratios. We further show that conductance switching data measured using ECT, in combination with other in situ-ex situ electrochemical measurements, is a powerful tool for correlating the change in conductance to that of the redox state, to our knowledge, this is the first report of this important correlation for MXene films. 2D ECTs can draw great inspiration and theoretical tools from the field of organic ECTs and have the potential to considerably extend the capabilities of transistors beyond those of conducting polymer ECTs, with added properties such as extreme heat resistance, tolerance for solvents, and higher conductivity for both electrons and ions than conducting polymers.

899 serious adverse events including 13 deaths, 7 strokes, 211 thromboembolic events, and 482 immune reactions: The untold story of cyanoacrylate adhesive closure.

OBJECTIVE: The aim was to retrieve and analyse the serious adverse events of venous occlusion systems used in cyanoacrylate adhesive closure (CAC) submitted to regulatory agencies. METHODS: The Total Product Life Cycle (TPLC) database of the US Food and Drug Administration (FDA), the Database of Adverse Event Notifications (DAEN) of the Australian Therapeutic Goods Administration (TGA), and the Yellow Card database of the UK Medicines and Healthcare Products Regulatory Agency (MHRA) were reviewed. Three Freedom of Information (FOI) requests had to be submitted to the MHRA to obtain data. RESULTS: The TPLC contained 899 reports which included 13 cases of death, 7 strokes, 211 thromboembolic events, and 482 immune reactions. The DAEN recorded three reportable adverse events, and the MHRA recorded seven adverse incidents including one death. CONCLUSION: CAC is associated with serious adverse events including death. These events are under-reported in the medical literature and only sub-optimally reported to the regulatory agencies.

Case report: Spontaneous abortion of monoamniotic twins at the third trimester of pregnancy in Camelus dromedarius.

Monoamniotic twins develop when a blastocyst spontaneously splits its progenitor cells, and each group of progenitor cells independently grows to become an individual. It is the rarest type of twin pregnancy and usually has significant developmental or congenital abnormalities, a higher rate of abortion, perinatal morbidity, and mortality. There is no information regarding monoamniotic twins in livestock species. Here, we reported a spontaneous abortion of monoamniotic twins in a dromedary camel at 278 days of gestation. Gonadorelin acetate (100 µg) was injected intramuscularly to induce ovulation in the recipient. A 7 days-old embryo produced by somatic cell nuclear transfer was transferred transcervically to the recipient. Early pregnancy was confirmed by an elevated level of serum progesterone followed by ultrasonography at 22 and 44 days after embryo transfer. A single sac was observed on 22 days while twins were evident 44 days after embryo transfer. Pregnancy was periodically monitored by the tail-up phenomenon. A ruptured fetal sac was observed on the ground having two fetuses. On autopsy, full-grown fetuses were found. Their bodies were separated. There was no congenital anomaly or any malformation in the fetuses. According to the reported chronology in human twins, we hypothesized that the blastocyst splitted before 13 days as it was monoamniotic and not conjoined. If the embryo splits within 4 to 8 days, it develops two amniotic sacs, and splitting after 13 days develops conjoined fetuses. To the authors' knowledge, this is the first reported case of monoamniotic twin abortion in dromedary camels. This report will increase awareness among practicing veterinarians and camel breeders about twin abortions.

Pigmentation of lower limbs: Contribution of haemosiderin and melanin in chronic venous insufficiency and related disorders.

BACKGROUND: To determine the composition of skin pigmentation in chronic venous insufficiency (CVI) and other less common vascular conditions of lower limbs. METHODS: Forty-five skin biopsies were obtained from 17 patients. Samples were taken from pigmented regions and compared with control non-lesional samples from the same patient. Perl's Prussian Blue was used to identify haemosiderin and Schmorl's for melanin. RESULTS: Seven patients presented with CVI, one with concurrent livedo vasculopathy (LV). One patient had LV only. Two patients had acroangiodermatitis (AAD). Six patients had post-sclerotherapy pigmentation (PSP), one with concurrent post-inflammatory hyperpigmentation (PIH). One patient had PIH only. The predominant pigment in CVI samples was haemosiderin. C5-C6 patients showed increased epidermal melanin. LV, AAD, and PSP samples showed dermal haemosiderin but no increase in epidermal melanin. PIH samples showed prominent epidermal melanin whilst no haemosiderin was detected. CONCLUSION: The predominant pigment in CVI and other vascular conditions was haemosiderin. Melanin was present in later stages of CVI (C5-C6) and in PIH.

Effect of the interval from GnRH administration after ovarian super-stimulation on the recovered oocytes, and effect of the transferred cloned blastocysts on the pregnancy rate and pregnancy loss in dromedary camel.

The present study was conducted to evaluate the number and maturity of the recovered oocytes after two intervals of in-vivo maturation. In addition to evaluating the effect of the developmental stage, as well as the number of cloned transferred blastocysts on the pregnancy rate and early pregnancy loss (EPL) in dromedary camel. The donor animals (n = 52) were super-stimulated using a single injection of 3000 IU of eCG followed by GnRH administration for oocyte maturation. Cumulus oocyte complexes (COCs) were collected by transvaginal ultrasound-guided aspiration (OPU) either 24-26 h or 18-20 h after GnRH administration. A fewer number of COCs with a lower percentage of oocyte maturity was observed at 24-26 h in comparison to 18-20 h. The effect of the cloned blastocysts' transferred number and developmental stage on the pregnancy rate and EPL was investigated. The total pregnancy rates at 10 days post-ET, 1 and 2 months were 21.9, 12.4, and 8.6%, respectively. Transfer of two or 3-4 embryos per surrogate was accompanied with a higher pregnancy rate at 1 and 2 months than a single embryo transfer. Rates of EPL were 43.5 and 60.1% at 1 and 2 months of pregnancy, respectively. The transfer of two embryos per surrogate was associated with a lower rate of EPL than ET of a single embryo at 1 and 2 months of pregnancy. Also, the ET of 3-4 embryos per surrogate showed a higher rate of EPL than the ET of two embryos at 2 months of pregnancy. ET of hatching (HG) blastocysts showed higher pregnancy rates and fewer EPL than ET of unhatched (UH) or fully hatched (HD) cloned blastocysts at 1 and 2 months of pregnancy. In conclusion, a high number of in-vivo matured oocytes can be recovered by ultrasound-guided transvaginal OPU from super-stimulated females using 3000 IU eCG and an interval of 18-20 h after GnRH administration. The transfer of two hatching cloned blastocytes per surrogate increases the pregnancy rate and decreases EPL in dromedary camels.

Sclerotherapy of lower limb veins: Indications, contraindications and treatment strategies to prevent complications - A consensus document of the International Union of Phlebology-2023.

BACKGROUND: Sclerotherapy is a non-invasive procedure commonly used to treat superficial venous disease, vascular malformations and other ectatic vascular lesions. While extremely rare, sclerotherapy may be complicated by serious adverse events. OBJECTIVES: To categorise contraindications to sclerotherapy based on the available scientific evidence. METHODS: An international, multi-disciplinary panel of phlebologists reviewed the available scientific evidence and developed consensus where evidence was lacking or limited. RESULTS: Absolute Contraindications to sclerotherapy where the risk of harm would outweigh any benefits include known hypersensitivity to sclerosing agents; acute venous thromboembolism (VTE); severe neurological or cardiac adverse events complicating a previous sclerotherapy treatment; severe acute systemic illness or infection; and critical limb ischaemia. Relative Contraindications to sclerotherapy where the potential benefits of the proposed treatment would outweigh the risk of harm or the risks may be mitigated by other measures include pregnancy, postpartum and breastfeeding; hypercoagulable states with risk of VTE; risk of neurological adverse events; risk of cardiac adverse events and poorly controlled chronic systemic illness. Conditions and circumstances where Warnings and Precautions should be considered before proceeding with sclerotherapy include risk of cutaneous necrosis or cosmetic complications such as pigmentation and telangiectatic matting; intake of medications such as the oral contraceptive and other exogenous oestrogens, disulfiram and minocycline; and psychosocial factors and psychiatric comorbidities that may increase the risk of adverse events or compromise optimal treatment outcomes. CONCLUSIONS: Sclerotherapy can achieve safe clinical outcomes provided that (1) patient-related risk factors and in particular all material risks are (1a) adequately identified and the risk benefit ratio is clearly and openly discussed with treatment candidates within a reasonable timeframe prior to the actual procedure; (1b) when an individual is not a suitable candidate for the proposed intervention, conservative treatment options including the option of 'no intervention as a treatment option' are discussed; (1c) complex cases are referred for treatment in controlled and standardised settings and by practitioners with more expertise in the field; (1d) only suitable individuals with no absolute contraindications or those with relative contraindications where the benefits outweigh the risks are offered intervention; (1e) if proceeding with intervention, appropriate prophylactic measures and other risk-mitigating strategies are adopted and appropriate follow-up is organised; and (2) procedure-related risk factors are minimised by ensuring the treating physicians (2a) have adequate training in general phlebology with additional training in duplex ultrasound, procedural phlebology and in particular sclerotherapy; (2b) maintain their knowledge and competency over time and (2c) review and optimise their treatment strategies and techniques on a regular basis to keep up with the ongoing progress in medical technology and contemporary scientific evidence.

Myopericytomatosis: A rare entity mimicking other vascular tumours and malformations.

Myopericytoma is a rare tumour which typically presents as a benign lesion that mimics features of other more common vascular tumours and malformations. We present a case of a symptomatic diffuse myopericytomatosis of the left abdomen presenting as multiple subcutaneous vascular tumours detected on ultrasound and treated with ultrasound-guided sclerotherapy.

Skin necrosis following sclerotherapy. Part 2: Risk minimisation and management strategies.

Tissue necrosis is a serious but rare complication of sclerotherapy. Early detection and targeted management are essential to prevent progression and minimise serious complications. In the first instalment of this paper, we reviewed the pathogenic mechanisms of post-sclerotherapy necrosis. Here, we describe risk minimisation and management strategies.Risk factors must be addressed to reduce the chance of necrosis following sclerotherapy. These may be treatment-related including poor choice of sclerosant type, concentration, volume or format, poor injection technique, suboptimal ultrasound visualisation and treatment of vessels in high-risk anatomical areas. Risk factors specific to individual patients should be identified and optimised pre-operatively.Tissue necrosis is more likely to occur with extravasation of irritant sclerosants such as absolute alcohol, sodium iodide, bleomycin and hypertonic saline, whereas extravasation of foam detergent sclerosants rarely results in tissue loss. Proposed treatments for extravasation of irritant sclerosants include infiltration of an isotonic fluid and hyaluronidase. Management of inadvertent intra-arterial injections may require admission for neurovascular observation and monitoring for ischaemia, intravenous systemic steroids, anticoagulation, thrombolysis and prostanoids infusion when required. Treatment of veno-arteriolar reflex vasospasm (VAR-VAS) necrosis follows the same protocol involving systemic steroids but rarely requires hospital admission and may not require anticoagulation.In general, treatment of post-sclerotherapy necrosis is challenging and most proposed treatment measures are not evidence-based and only supported by anecdotal personal experience of clinicians. Despite all measures, once the necrosis has set in, it is very difficult to reverse the process and all measures described here may only be useful in prevention of progression and extension of the ulceration.Mid to long-term measures include addressing exacerbating factors, management of medical and psychosocial comorbidities, treatment of secondary infections and referrals to relevant specialists. All ulcers should be managed with compression and prescribed dressing regimes in line with the healing stage of the ulcer.

Insights from one thousand cloned dogs.

Animal cloning has been popularized for more than two decades, since the birth of Dolly the Sheep 25 years ago in 1996. There has been an apparent waning of interest in cloning, evident by a reduced number of reports. Over 1500 dogs, representing approximately 20% of the American Kennel Club's recognized breeds, have now been cloned, making the dog (Canis familiaris) one of the most successfully cloned mammals. Dogs have a unique relationship with humans, dating to prehistory, and a high degree of genome homology to humans. A number of phenotypic variations, rarely recorded in natural reproduction have been observed in in these more than 1000 clones. These observations differ between donors and their clones, and between clones from the same donor, indicating a non-genetic effect. These differences cannot be fully explained by current understandings but point to epigenetic and cellular reprograming effects of somatic cell nuclear transfer. Notably, some phenotypic variations have been reversed through further cloning. Here we summarize these observations and elaborate on the cloning procedure.

Influence of PMSG on Superstimulation and Embryo Development Following Somatic Cell Nuclear Transfer in Holstein Cows in the United Arab Emirates.

The present study investigated the effect of superstimulation to improve in vitro embryo production in the Gulf area, where the temperature is high. Holstein cows were classified into the control and superstimulation groups. Superstimulation was induced with a single intramuscular injection of pregnant mare serum gonadotropin (PMSG; 2500 IU) on day 14 of the estrus cycle (day 0; estrus). The development of follicles was evaluated by ultrasonography of the ovaries daily. At 40 h after the PMSG injection, oocytes were collected by the ovum pick-up (OPU) technique. OPU was performed at the same stage of the estrus cycle in the control group as in the superstimulation group. The number of follicles with a diameter of more than 6 mm and the number of retrieved cumulus-oocyte complexes were significantly higher in the superstimulation group than in the control group. Furthermore, the maturation rate was higher in the superstimulation group than in the control group. Cloned embryos were produced by somatic cell nuclear transfer using matured oocytes. The cleavage and blastocyst formation rates were significantly higher in the superstimulation group than in the control group. In conclusion, a single injection of PMSG can facilitate the efficient production of cloned cow embryos.

Skin necrosis following sclerotherapy. Part 1: Differential diagnosis based on classification of pathogenic mechanisms.

Background: Tissue necrosis is a significant but uncommon complication of sclerotherapy. The pathogenic mechanisms of this often-debilitating complication have been poorly described in the literature.Purpose: To elucidate the pathological mechanisms, we propose a morphological approach to classify sclerotherapy-induced skin necrosis into two categories of round and stellate (star-like) necrosis.Research Design: Comprehensive literature review was conducted.Results: Round necrosis is typically caused by extravasation of sclerosants. It typically presents as an ulcer with smooth and non-geographic borders. Historically, extravasation has been cited as the main cause of sclerotherapy-related necrosis. While this may be the case with osmotic or irritant sclerosants, it is far less likely with the use of detergent agents particularly in the foam format.The more commonly encountered pattern of stellate necrosis is an ischaemic ulcer secondary to arterial/arteriolar occlusion. In contrast to round necrosis, stellate necrosis follows an intra-vascular injection of sclerosants such as an inadvertent intra-arterial injection. But more frequently, stellate necrosis may follow a perfectly executed intra-venous or intra-telangiectatic delivery of sclerosants. Several pathogenic pathways can be considered. The physiologic response of veno-arteriolar reflex vasospasm (VAR-VAS) is possibly the most frequent pathway. It follows a high-pressure injection of the sclerosant in a target vein resulting in a rapid rise of intravenous pressures which in-turn would trigger a sympathetic neuronal reflex vasospasm of the pre-capillary sphincters and a corresponding opening of the normally closed arterio-venous anastomoses (AVAs). This communication would allow entry of the sclerosing agent into the arteriolar side of the circulation resulting in arteriolar occlusion and infarction of the corresponding skin. Similarly, an intravenous administration of sclerosants in the vicinity of defective boundary valves or persistently open AVAs can result in the entry of detergent agents into the arteriolar side of the microvasculature causing an ischemic stellate ulcer.Conclusions: In this first instalment of these two-part series, we review the pathogenic mechanisms of post-sclerotherapy necrosis. In the second instalment, we describe risk minimisation and management strategies.

Treatment of facial hypertrophic capillary malformations with tumescent-assisted sclerotherapy.

Facial capillary malformations (CMs) become hypertrophic and nodular overtime and pose great therapeutic challenge. Here, we describe safe and effective use of tumescent-assisted sclerotherapy (TAS) in conjunction with yellow vascular laser (577 nm) for the treatment of HFCMs. Three patients underwent TAS were included in the case series, and complete resolution in nodularity was achieved in all patients with TAS, with no major complications such as skin necrosis, distal embolisation, blindness and neurological adverse events such as stroke or TIA occurred in any patients.

Treatment of venous malformations with tumescent-assisted sclero-embolic and ablative lasers (SEALs): Safe and effective long-term outcomes.

BACKGROUND: Perivascular infiltration of tumescent anaesthesia (TA) is an essential element of endovenous thermal ablative procedures employed to treat superficial venous disease. In addition to anaesthesia, TA is administered to achieve vessel wall approximation and to protect surrounding structures from thermal damage. However, its role in the treatment of venous malformations (VMs) has not been established. OBJECTIVES: To assess the safety and efficacy of tumescent-assisted thermal and chemical ablative methods in the treatment of VMs. METHODS: Adult and paediatric patients presenting with VMs were treated using a combination of endovenous laser ablation, foam embolo-sclerotherapy and liquid embolisation using n-BCA. All procedures were ultrasound-guided. Treatment outcomes were assessed in early and late follow-ups. To assess the efficacy of TA in achieving vessel wall approximation, cross-sectional lesional diameters were measured by ultrasound, before and after the administration of TA during endovenous procedures. RESULTS: In a 12 month period, 22 patients recruited in the study presented with 27 VMs which included 23 extra-truncular lesions (16 subcutaneous and seven intramuscular) and four truncular anomalies. On average the subcutaneous lesions measured 5.5 mm (1.9-24.5 mm) in diameter, intramuscular lesions measured 9.2 mm (5.9-15.1 mm) and truncular anomalies measured 4.9 mm (1.2-12 mm) in diameter. Perivascular infiltration of TA resulted in a significant reduction in vessel calibre (90% reduction on average). Intramuscular VMs were less compressible with TA (69.2% reduction) compared to subcutaneous lesions (98% reduction). Truncular anomalies such as the embryonic marginal vein achieved complete approximation (100% reduction). Procedures were safely tolerated with no major complications such as thromboembolism, stroke, nerve damage or tissue necrosis. Most patients had significant clinical as well as ultrasonographic improvement. CONCLUSION: Tumescent-assisted endovenous laser ablation and foam sclerotherapy provides safe and effective outcomes in patients with a variety of VMs.

A case-control study of clinical characteristics and risk factors of symptomatic postpartum pubic symphysis diastasis.

Postpartum pubic symphysis diastasis (PPSD) refers to the separation of pubic symphysis after delivery. It is typically diagnosed based on clinical symptoms and radiologic findings. This study tried to assess clinical characteristics and risk factors of PPSD. This was a nested case-control study matched for year of delivery and gestational age at delivery using a retrospective cohort of women who delivered vaginally at a single institution. The incidence of PPSD was 0.156% (33/21,131). The incidence rate increased from 0.08% (7/9328) in 2000-2004 to 0.13% (9/7138) in 2005-2009 and to 0.36% (17/4665) in 2010-2016, simultaneously with an increase of maternal age (30.7 ± 3.5 years in 2000-2004 to 31.8 ± 3.8 years in 2005-2009 and 32.8 ± 3.8 years in 2010-2016). Nulliparity was associated with a higher incidence of PPSD (81.8% in cases vs. 57.6% in controls, p = 0.01). Other factors including pre-pregnancy body mass index, weight gain during pregnancy, gestational diabetes, induction of labor, duration of labor, epidural anesthesia, vacuum-assisted delivery, episiotomy, neonatal sex and birth weight failed to show difference between the two groups. In short, the incidence of PPSD increased with time along with an increase of maternal age. Nulliparity was the only significant risk factor for PPSD.

An analysis of the prevalence of osteoporosis and osteopenia in patients with epidermolysis bullosa: A cross-sectional study.

BACKGROUND: Epidermolysis bullosa (EB) patients have multiple risk factors for osteoporosis. There is limited literature describing the prevalence of bone health in EB, particularly in adults and less severe EB types. OBJECTIVES: To investigate the prevalence of osteopenia or osteoporosis in EB patients from the Australasian Epidermolysis Bullosa Registry (AEBR). METHODS: Of 417 AEBR patients, 72 underwent a dual energy X-ray absorptiometry scan. Bone mineral density (BMD) T and Z-scores, EB Disease Activity and Scarring Index (EBDASI), and Quality of Life in EB (QOLEB) scores were obtained. RESULTS: T-scores of RDEB patients were significantly lower than the diagnostic cut-off value for osteopenia. EBDASI and QOLEB scores were inversely correlated with Z-scores. The prevalence of osteoporosis in adults was 75% in severe EB types (RDEB and JEB). In adults with less severe types (EBS and DDEB), the prevalence of osteopenia was 50% and 33%, respectively. CONCLUSIONS: This is the largest study of osteoporosis in EB to date and the first to include adult patients with EBS. The high prevalence of osteoporosis and osteopenia identified in these patients warrants larger, collaborative international studies. Nevertheless, EB patients with high disease severity and QOL scores, irrespective of type, should receive early osteoporosis screening and prophylaxis.

Spousal Concordance regarding Lifestyle Factors and Chronic Diseases among Couples Visiting Primary Care Providers in Korea.

BACKGROUND: Few studies have been conducted in Korea on concordance regarding chronic diseases and lifestyle factors among couples. We, therefore, evaluated spousal concordance regarding lifestyle factors and chronic diseases among Korean couples. METHODS: A total 1,040 participants (520 couples) who visited family physicians were recruited from 22 hospitals. All participants were aged ≥40 years. Participants completed questionnaires on smoking, drinking, physical activity, and irregular eating habits, including skipping breakfast. We estimated the spousal concordance regarding lifestyle factors and chronic diseases using McNemar tests and logistic regression analysis. RESULTS: The concordance rate was high among couples who shared unhealthy behaviors, such as low physical activity, irregular diet, and skipping breakfast (P<0.05). When cardiovascular risk factors such as overweight (odds ratio [OR], 1.73; 95% confidence interval [CI], 1.14-2.63), hypertension (OR, 1.88; 95% CI, 1.23-2.86), or hyperlipidemia (OR, 2.41; 95% CI, 1.60-3.64) were prevalent among husbands, the odds that their wives also had the same risk factors at the same time was significantly high. The odds of being depressed when the spouse was depressed were also significantly high in both men (OR, 5.54; 95% CI, 2.19-13.96) and women (OR, 4.52; 95% CI, 1.77-11.53). CONCLUSION: There was a high level of concordance regarding lifestyle factors among couples, which could lead to an increase in the prevalence of chronic diseases among couples. In addition, if a spouse has depression, the odds of their partner also having depression was high.

Long-term outcomes of single-port laparoscopic myomectomy using a modified suture technique.

OBJECTIVE: To evaluate the long-term outcomes, including the pregnancy outcome and recurrence rate after single-port laparoscopic myomectomy (LM) using a modified suture technique with a Hem-o-lok clip (Choi's LM) and conventional 4-port LM. METHODS: A retrospective study of patients who underwent Choi's LM (n=55) and 4-port LM (n=102) in a single institutional hospital was conducted. Patients with <3 symptomatic myomas sized <10 cm each and operated on by a single surgeon were included. Recurrence was confirmed when a myoma measuring ≥3 cm was detected. RESULTS: The patients in both groups had similar demographic characteristics. Single (76.4% vs. 62.7%) and intramural (52.7% vs. 56.9%) tumors were commonly detected in both groups in the mean diameter (6.8±1.5 cm vs. 7.0±1.6 cm; P=0.40). In Choi's LM, 16 patients (29.1%) needed an additional port; those who were nulliparous and/or had a large leiomyoma more frequently required an additional port (P=0.023 and 0.04, respectively). During a median follow-up period of 69 months, 17 patients (7.1% vs. 14.6%) had recurrence. The size of dominant myomas at recurrence was significantly smaller in patients who underwent Choi's LM (3.4±0.7 cm vs. 5.7±2.4 cm; P=0.004). All 13 patients in both groups who successfully conceived had a full-term delivery. No major complications occurred during pregnancy. CONCLUSION: Although an additional port was frequently used, the long-term outcomes of patients who experienced recurrence and pregnancy after Choi's LM were acceptable. Considering its usability, Choi's LM is feasible for the treatment of uterine leiomyoma.

Religion and Health Behaviors in Primary Care Patients.

BACKGROUND: Few studies have investigated the association between religion and health behaviors in Korea, where various religions coexist. The present study aimed to investigate the association between religion and health behaviors among primary care patients in Korea. METHODS: We analyzed data from the Family Cohort Study in Primary Care. Among the 1,040 participants in the cohort, 973 of those who had reported their religion were included in the analysis. Participants completed standardized questionnaires that included religious status and lifestyle factors, such as physical activity, smoking status, drinking status, and dietary habits. The association between religion and health behaviors was analyzed using multivariate logistic regression models. RESULTS: Among the 973 participants, 345 (35.5%) were Christian, 153 (15.7%) were Roman Catholic, 308 (31.7%) were Buddhist, and 163 (16.8%) did not have any religion. Compared with those without a religion, the odds ratio (OR) for vigorous physical activity (OR, 1.52; 95% confidence interval [CI], 1.01-2.28) increased, and that for binge drinking (OR, 0.67; 95% CI, 0.46-0.78) and problematic drinking (OR, 0.59; 95% CI, 0.35-0.99) decreased among participants with a religion. Compared with those without a religion, Catholics were more likely to engage in vigorous physical activity (OR, 2.20; 95% CI, 1.31-3.67), whereas Christians were less likely to engage in heavy (OR, 0.50; 95% CI, 0.30-0.84), binge (OR, 0.35; 95% CI, 0.22-0.54), and problematic drinking (OR, 0.46; 95% CI, 0.25-0.86). Smoking, meal regularity, and breakfast consumption were not associated with religion. CONCLUSION: The status of drinking and physical activities were different according to religion. As religion is one of the psychosocial characteristics of patients, knowing patients' religion can be helpful for primary physicians.
