Abstract
Background
Hepatoid adenocarcinoma of the stomach (HAS) is a highly malignant and rare extrahepatic tumor. The prognosis is controversial because of its rarity and the lack of multi-center cohort studies, especially on the influence of serum Alpha-fetoprotein (AFP) level on prognosis. We aimed to analyze the clinicopathological characteristics and prognosis of HAS, particularly the effect of serum AFP on the prognosis of HAS.

Methods
We retrospectively reviewed clinical data of one HAS patient treated at our institution in 2019 and of 252 patients reported between 1984 and 2020 in research databases.

Results
Among these patients, 60.1% were > 60 years, 51% had lesions in the gastric antrum, and 51.0% (73/143) had the ulcerative lesion type. The preoperative elevated levels of serum alpha-fetoprotein (AFP) were detected in most patients (76.7%). Lymph-node (84.6%) and preoperative liver metastasis (39.1%) were often found. The high-AFP group was characterized by a higher rate of stage IV (P = 0.000682) and liver metastasis (P = 0.000068). The 1-, 3-and 5-year progression-free survival(PFS) rates were 41%, 18%, and 0%, and the 1-, 3-, and 5-year overall survival (OS) rates were 64%, 26%, and 21%, respectively. The survival analysis showed that OS was significantly shorter for HAS with high-AFP (> 300 ng/ml) than with low-AFP (≤ 300 ng/ml) (P = 0.023). The univariate analysis indicated that the OS of HAS was associated with tumor location, pTNM stage, lymph-node metastasis, surgical resection, and serum AFP > 300 ng/ml. However,the prognostic factors for PFS was only pTNM stage and surgical resection. The multivariate analysis confirmed that the independent prognostic factor affecting OS of HAS included pTNM stage and surgical resection.

Conclusions
Liver metastasis was increasingly more likely with increasingly higher serum AFP, but the prognosis of HAS is not necessarily poor. Serum AFP level is an important prognostic indicator in HAS and should be monitored.

Abstract
Background
Leprosy is an ancient infectious disease with an annual global incidence of around 200,000 over the past decade. Since 2018, the World Health Organization (WHO) recommends single-dose rifampicin as post-exposure prophylaxis (SDR-PEP) for contacts of leprosy patients. The Post ExpOsure Prophylaxis for Leprosy (PEOPLE) trial evaluated PEP with a double dose of rifampicin in Comoros and Madagascar. Preliminary results of this trial show some reduction in leprosy incidence in intervention villages but a stronger regimen may be beneficial. The objective of the current Bedaquiline Enhanced ExpOsure Prophylaxis for LEprosy trial (BE-PEOPLE) is to explore effectiveness of a combination of bedaquiline and rifampicin as PEP.

Methods
BE-PEOPLE is a cluster-randomized trial in which 44 clusters in Comoros will be randomized to two study arms. Door-to-door screening will be conducted annually during four years, leprosy patients identified will be offered standard of care treatment. Based on study arm, contacts aged five years and above and living within a 100-meter radius of an index case will either receive bedaquiline (400-800 mg) and rifampicin (150-600 mg) or only rifampicin (150–600 mg). Contacts aged two to four years will receive rifampicin only. Household contacts randomized to the bedaquiline plus rifampicin arm will receive a second dose four weeks later. Incidence rate ratios of leprosy comparing contacts who received either of the PEP regimens will be the primary outcome. We will monitor resistance to rifampicin and/or bedaquiline through molecular surveillance in all incident tuberculosis and leprosy patients nationwide. At the end of the study, we will assess anti-M. leprae PGL-I IgM seropositivity as a proxy for the population burden of M. leprae infection in 8 villages (17,000 individuals) that were surveyed earlier as part of the PEOPLE trial.

Discussion
The COLEP trial on PEP in Bangladesh documented a reduction of 57% in incidence of leprosy among contacts treated with SDR-PEP after two years, which led to the WHO recommendation of SDR-PEP. Preliminary results of the PEOPLE trial show a lesser reduction in incidence. The BE-PEOPLE trial will explore whether reinforcing SDR-PEP with bedaquiline increases effectiveness and more rapidly reduces the incidence of leprosy, compared to SDR-PEP alone.

Clinicians’ experiences in signposting an online mental health resource to expectant mothers: a qualitative study
Authors: Saxild Sofie , Wilson Philip , de Voss Sarah , Overbeck Gritt 
Published: May 2023

AbstractBackgroundPoor maternal mental well-being and a lack of secure parent-infant attachment, have been identified as important factors associated with adverse mental health outcomes later in a child’s life. Interventions designed to care for maternal mental well-being during pregnancy and early parenthood, are therefore likely to support healthy child development. Mentalization is a skill parents can practice, improving the emotional bond to the child, offering insights into their own and the child’s mental states and potentially improving parental mental well-being. Most pregnant women in Denmark schedule antenatal consultations in general practice, potentially offering a solid platform to promote web-based interventions aiming to enhance mentalization skills. Signposting towards online resources has several advantages including high accessibility, ease of distribution and cost-effectiveness. We aimed to explore the attitudes and experiences of clinicians in general practice in signposting women towards a web-intervention to increase parental mentalization skills.MethodsThe intervention was offered to pregnant women at their primary preventive antenatal consultation in Danish general practice around week eight of pregnancy, and was designed to be incorporated into the following antenatal- and pediatric consultations until the child’s second birthday. Semi-structured interviews about clinicians’ experiences with signposting the intervention were conducted with 11 general practitioners (GP), three practice midwives (MW) and one practice nurse (NR).ResultsClinicians wanted to enhance the focus on mental well-being in pregnancy and early childhood during preventive consultations. The main barriers to signposting the web-program were decreasing motivation over time, lack of financial viability and time limitations. Utilizing a psychoeducational web-intervention was generally accepted by clinicians, but ideally not carried out solely in general practice.ConclusionSignposting web-programs to improve parental mentalization skills can be welcomed by clinicians in general practice but need to be more tailored to suit the everyday workflow of the clinics. Addressing parental mentalization remains largely unchartered territory for pregnant women and clinicians alike, therefore training clinicians on the subject and its presentation should be offered.Trial registrationThe study is part of a larger project that has been approved by the Research Ethics Committee at the University of Copenhagen, Nov. 2019 (reference number 504–0111/19–5000).

Abstract
Background
Retinitis Pigmentosa (RP) is a clinically and genetically progressive retinal dystrophy associated with severe visual impairments and sometimes blindness, the most common syndromic form of which is Usher syndrome (USH). This study aimed to further increase understanding of the spectrum of RP in the Khyber Pakhtunkhwa region of Pakistan.

Methodology
Four consanguineous families of Pashtun ethnic group were investigated which were referred by the local collaborating ophthalmologists. In total 42 individuals in four families were recruited and investigated using whole exome and dideoxy sequencing. Among them, 20 were affected individuals including 6 in both family 1 and 2, 5 in family 3 and 3 in family 4.

Result
Pathogenic gene variants were identified in all four families, including two in cone dystrophy and RP genes in the same family (PDE6C; c.480delG, p.Asn161ThrfsTer33 and TULP1; c.238 C > T, p.Gln80Ter) with double-homozygous individuals presenting with more severe disease. Other pathogenic variants were identified in MERTK (c.2194C > T, p.Arg732Ter), RHO (c.448G > A, p.Glu150Lys) associated with non-syndromic RP, and MYO7A (c.487G > A, p.Gly163Arg) associated with USH. In addition, the reported variants were of clinical significance as the PDE6C variant was detected novel, whereas TULP1, MERTK, and MYO7A variants were detected rare and first time found segregating with retinal dystrophies in Pakistani consanguineous families.

Conclusions
This study increases knowledge of the genetic basis of retinal dystrophies in families from Pakistan providing information important for genetic testing and diagnostic provision particularly from the Khyber Pakhtunkhwa region.
A case of two connected stents deployed during iStent inject W surgery
Authors: Shimada Ayaka , Ichioka Sho , Ishida Akiko , Kaidzu Sachiko , Tanito Masaki 
Published: May 2023

Abstract
Background
We report a case with two connected stents ejected simultaneously during an iStent inject W surgery, a modified second-generation iStent Trabecular Micro-Bypass System.

Case presentation
A 57-year-old woman with primary open-angle glaucoma underwent a combined cataract and iStent inject W surgery in her left eye. After the trabecular meshwork/Schlemm’s canal was pierced by the trocar of injector, the delivery button was pressed a first time, but the stent was not ejected. After the button was pressed a second time, connected two stents were ejected. After removing the dislocated stents from the anterior chamber, two stents were implanted into the desired places using another injector. Except for mild hyphema, no postoperative complication occurred. Stereomicroscopic observation showed that the two stents were connected by a broken trocar shaft. An X-ray showed that the trocar shaft was broken at the part referred to as the “sprayed trocar”. Scanning electron microscopy showed that the surface features of the broken trocar and trocar tip represented tensile failure.

Conclusions
Although rare, considering that the damage was seen at the structurally weak part (i.e., sprayed trocar), the same phenomenon can happen. For patient safety, surgeons are recommended to inspect the device when the deployment of either the first or second stent is unsuccessful during the iStent inject surgery.
Association between dating app use and unhealthy weight control behaviors and muscle enhancing behaviors in sexual minority men: a cross-sectional study
Authors: Tran Alvin , Darboe Mabintou , Goyal Anirudh , Birk Nick 
Published: May 2023

Abstract
Background
Body image concerns are prevalent and are viewed as risk factors for engaging in unhealthy weight control behaviors (UWCBs), such as purging, fasting, and the misuse of laxatives and diet pills. Studies have also linked UWCBs to the development of eating disorders. In the United States (U.S.), sexual minority men (e.g., bisexual, gay, and men who have sex with men) are prone to UWCBs often as a result of societal pressures to achieve certain standards of appearance – of which are often perpetuated through various media platforms. A growing number of studies have explored the possible role mobile dating applications (“dating apps”) play in contributing to UWCBs. To our knowledge, such studies have not explored this possible relationship between dating apps and UWCBs in sexual minority men (SMM). To fill this gap in the scientific literature, the present study assessed the association between dating app use and UWCBs and muscle enhancing behaviors among a sample of adult SMM in the U.S.

Method
549 SMM participated in an anonymous survey from Qualtrics Survey Panels. UWCBs and muscle enhancing behaviors were assessed through items adapted from national surveys. Body image dissatisfaction was assessed using the Male Body Attitudes Scales. Participants also reported their history of dating app use. We performed descriptive statistics, chi-square tests, and student’s t-tests. Multivariable logistic regression models assessed the relationship between dating app use and UWCBs and muscle enhancing behaviors.

Results
Dating app users had significantly higher body image dissatisfaction scores than non-users. Dating app users also demonstrated significantly elevated odds of engaging in four UWCBs and muscle enhancing behaviors: laxatives, diet pills, muscle-building supplements, and protein powders.

Conclusions
This is one of the first studies to assess dating app use and its association with UWCBs and muscle enhancing behaviors in SMM. Increased surveillance and detection for such behaviors among SMM, particularly those using dating apps, are needed.

Published: May 2023

Abstract
Background
Onchocerciasis is a disease of public health concern due to the devastating consequences of the disease which impacts negatively on the lives of the people. The negative impact of the disease may affect its perception and lead to the adoption of some coping strategies. Therefore, understanding the disease perception, impacts and coping strategies used by onchocerciasis patients will help plan health interventions aimed at improving their general well-being.

Methods
This was a community-based study that employed a qualitative method through Key informant interviews (KII) with program managers and focus group discussions (FGD) among people who had Onchocerciasis. Four sessions of FGDs with a total of thirty-two (32) participants and eleven KIIs were conducted to ascertain their in-depth experience in five thematic areas.

Results
In these communities, onchocerciasis is perceived to have been caused mainly by the bite of blackflies. Other presumed causes by the patients included drinking polluted water, poor environmental sanitation and witchcraft. The disease had a significant detrimental influence on both the physical and financial aspects of life with limited emotional and social impacts. The long-term clinical manifestations of onchocerciasis triggered pain and insufficient mobility. Thus, onchocerciasis patients experienced impairment in normal daily life activities (farming, etc.), dependency, depression and inability to participate in social events. These manifestations stimulated various coping strategies, mainly, nodulectomy by traditional healers. Others included self-medication, taking an overdose of ivermectin, and the use of alcohol.

Conclusion
Misconceptions about the cause of onchocerciasis still exist among people with the disease. The consequences of the disease impact negatively on various aspects of their lives and stimulate various coping strategies. Therefore, health promotion messages to the public should aim at dispelling misconceptions about the disease and promote healthy coping strategies.
Platelet-rich plasma treatment for talar cartilage repair: a systematic review and meta-analysis
Authors: Peng Jialei , Wang Qian , Xu Yang , He Hongchen 
Published: May 2023

Abstract
Purpose
To systematically review the studies regarding to the safety, efficacy and application methods of PRP in promoting the talar cartilage repair.

Methods
A systematic review was performed by searching PubMed, Web of Science, OVID and EMBASE to identify studies that compared the clinical efficacy of PRP for talar cartilage repair. Main outcome was the American Orthopedic Foot and Ankle Society (AOFAS) score for function and Visual Analog Scale (VAS) for pain was the second outcome.

Results
A total of 10 studies were included in this systematic review, including 4 randomized controlled trials, 1 controlled trial, 3 case series and 2 cohort studies. Four RCTs were analyzed using meta-analysis. For all outcomes, statistical results favored PRP group (AOFAS: MD = 7.84; 95% CI= [-0.13, 15.80], I2 = 83%, P < 0.01; VAS: MD = 1.86; 95% CI= [0.68, 3.04], I2 = 85%, P < 0.01). There were almost no reports of adverse events related to PRP intervention. Subgroup analysis showed that whether PRP was used alone or combined with other treatments could result in high heterogeneity but no more specific factors were identified to contribute to this.

Conclusion
PRP is safe and effective for talar cartilage repair. In addition to the standardization of PRP preparation and application, it is necessary to distinguish the effects of PRP used alone or in combination with other treatments. In PRP studies, surgical treatment of talar cartilage repair remains the mainstream. The regulation of PRP in surgical applications are worth exploring. The most relative component is the mesenchymal stem cell because it is the only exposed chondrocyte precursor in the articular cavity whether it is microfracture or cell transplantation.

Trial registration
The study was registered in the PROSPERO International prospective register of systematic reviews (CRD42022360183).
Silicone ring tourniquet could be a substitute for a conventional tourniquet in total knee arthroplasty with a longer surgical field: a prospective comparative study in simultaneous total knee arthroplasty
Authors: Lee Tae sung , Park Kwan Kyu , Cho Byung Woo , Lee Woo-Suk , Kwon Hyuck Min 
Published: May 2023

Abstract
Introduction
This study aimed to compare the clinical outcomes of silicon ring tourniquets and conventional pneumatic tourniquets in total knee arthroplasty (TKA). The study compared the operation time, total bleeding amount, length from the tourniquet distal end to the patella superior pole (L_TP), and complications related to the two tourniquet application methods and attempted to determine whether the silicon ring tourniquet has advantages over conventional pneumatic tourniquets.

Materials and methods
This prospective comparative study included 30 patients who underwent bilateral simultaneous TKA for degenerative osteoarthritis in August to December 2021. All patients underwent TKA on one side with a conventional pneumatic tourniquet, while TKA on the other side with a silicon ring tourniquet. The primary outcomes were the L_TP, operation time, tourniquet time, total bleeding amount, total drainage amount, and postoperative visual analog scale (VAS) score of the tourniquet applied site at 6, 24, and 48 h postoperatively. The secondary outcome was tourniquet-related complications in both groups.

Results
L_TP was significantly longer in the silicon ring tourniquet group compared with that in the pneumatic tourniquet group (20.22 ± 2.74 cm versus 15.12 ± 2.40, p < 0.001). No significant difference was found in other results. The tourniquet applied site pain was less in the silicon ring tourniquet group (p = 0.037).

Conclusions
Silicon ring tourniquet application resulted in better clinical outcomes than conventional pneumatic tourniquets in TKA. Because we can obtain a wider surgical field using silicon ring tourniquets without complications, silicon ring tourniquets could be a substitute for conventional pneumatic tourniquets in total knee arthroplasty or distal femoral surgeries.
Comparison of the ALPS and PHILOS plating systems in proximal humeral fracture fixation – a retrospective study

Published: May 2023

Abstract
Background
Open reduction and plate osteosynthesis are considered as a successful technique for the treatment of proximal humerus fracture (PHF) despite high complication rates. The objective of our study was to review the clinical outcome and complications of the Anatomic Locking Plate System (ALPS) and compare it to the Proximal Humeral Internal Locking System (PHILOS). Our hypothesis was that ranges of motion (ROM) were superior and complication rates were lower with ALPS.

Methods
Twenty patients treated with ALPS for PHF were retrospectively compared to 27 patients treated with PHILOS. Union, ROM and complications were clinically and radiologically assessed at 6 weeks, 3, 6, 12 and 18–24 months post-operatively.

Results
Mean age was 52 ± 14 in the ALPS group and 58 ± 13 in the PHILOS group. Last follow-ups were conducted at a mean of 20.6 ± 4.8 months. Mean shoulder abduction was superior with ALPS by 14° (p-value = 0.036), 15° (p-value = 0.049), and 15° (p-value = 0.049) at 3, 6, and 12 months respectively. Mean shoulder external rotation was superior with ALPS by 11° (p-value = 0.032), 15° (p-value = 0.010) and 12° (p-value = 0.016) at 6 weeks, 3 and 6 months respectively. At the end of the follow-up, ROM remained better with ALPS, but not significantly. Complication rates over 21 months reached 20% with ALPS and 48% with PHILOS (p-value = 0.045). Implant removal rates reached 10% with ALPS and 37% with PHILOS (p-value = 0.036). Avascular necrosis was the only cause for hardware removal in the ALPS group.

Conclusion
The ALPS group showed better clinical outcomes with faster recovery in abduction and external rotation, although no difference in ROM remained after 21 months. Additionally, the complications rate was lower at last follow up. In our experience, the ALPS plating system is an effective management option in some PHF.
