Hysteroscopy is an endoscopic diagnostic and therapeutic method traditionally performed under general anesthesia but increasingly under local anesthesia. Today, it is considered the gold standard in gynecology. This minimally invasive procedure allows for a detailed assessment of the uterine cavity's interior and the removal of abnormal changes within it and is applicable to patients of all ages. Background/Objectives: The purpose of the present study was to evaluate pain during hysteroscopy under local anesthesia at different stages of the procedure, identifying which stage is the most painful (GUBBINI Mini Hystero-Resectoscope; Tontarra Medizintechnik, Tuttlingen, Germany). Methods: The study included patients between the ages of 21 and 80 years. They were divided into two groups: the diagnostic hysteroscopy (HD) and the operative hysteroscopy (HO) groups. Pain measurements on the VAS scale were taken at each stage of the hysteroscopic procedure. After each stage, the operator asked the patient to indicate the maximum perceived pain value: after pericervical anesthesia was administered (VAS1), during the installation of equipment (between the removal of the speculum and the insertion of the hysteroscope into the vagina) (VAS2), after insertion of the hysteroscope and visualization of the external orifice of the cervical canal (VAS3), after passage of the hysteroscope through the cervical canal (VAS4), and after completion of the procedure in the uterine cavity (VAS5). The duration of each stage of the procedure was measured with a stopwatch: administration of pericervical anesthesia (T1), time between the removal of the speculum and the insertion of the hysteroscope into the vagina (T2), insertion of the hysteroscope into the vagina until the outer orifice of the cervical canal became visible (T3), passage of the hysteroscope through the cervical canal (T4), and the hysteroscopy procedure itself (T5). Results: The highest pain rating was for the canal passage stage (VAS4: 2.47 ± 2.48 points), followed by the procedure itself (VAS5: 2.12 ± 2.33 points). Anesthesia was also reported as quite painful, while the lowest pain was noted during the assembly stage. Overall pain scores for the entire procedure (VASmax) ranged from 3.5 ± 2.37. Conclusion: In conclusion, we found that the passage through the cervical canal was the most painful moment. Overall, hysteroscopy under pericervical anesthesia was not associated with significant pain. Special attention should be given to postmenopausal patients, as they experience more pain during the passage of the hysteroscope through the cervical canal. This group may benefit from additional pain management strategies during the procedure. [ABSTRACT FROM AUTHOR]

Background: Total laparoscopic hysterectomy (TLH) is becoming an increasingly popular treatment in endometrial cancer. Intra-abdominal or vaginal uterus morcellation are well described and routinely practiced techniques in removing a benign bulky uterus but contraindicated in endometrial cancer. In malignancy, the uterus needs to be removed intact to avoid intraperitoneal spillage of the endometrial cancer cells, and a uterine size of 12 gestational weeks (g.w.) or larger has been considered a contraindication for the laparoscopic approach. The aim of our study was to evaluate the feasibility and safety of a sealed vaginal morcellation technique in a bag for endometrial cancer laparoscopic treatment., Methods: We prospectively scheduled 12 patients affected by endometrial cancer with uterus bigger than 12 g.w. for endometrial cancer laparoscopic treatment. After performing TLH, a sterile plastic wrapping bag was inserted by a 12 mm camera port by rolling it onto the blunt probe. The uterus was covered from the fundus to the cervix, placing the free edges of the bag down into the manipulator cup with two blunt graspers. The specimen completely covered by the bag was then pushed down under direct laparoscopic vision through colpotomy and pulled out from the vagina. The uterus was morcellated by the vaginal route., Results: All patients underwent laparoscopic treatment with vaginal uterine morcellation. The mean uterus weight was 290.8 ± 79.7 g with a mean morcellation operative time of 12.1 min. All vaginal morcellations were completed successfully. All patients were without evidence of local or distant recurrence at the median follow-up time of 18 months., Conclusions: This technique allows the surgeon to morcellate a bulky uterus in cases of endometrial cancer and reduces the chance of neoplastic cell spillage during debulking at TLH. Vaginal morcellation following oncologic rules permits a rapid uterine extraction and may avoid a number of unnecessary laparotomies.

Purpose: We investigated the feasibility and acceptability of office hysteroscopic polypectomy using a new continuous-flow operative 16 Fr Gubbini's mini-resectoscope. This is a prospective clinical study (Canadian Task Force classification III)., Methods: The office hysteroscopic polypectomy was performed with a mini-resectoscope without analgesia or anesthesia. We evaluated the polyp size and the number, the effectiveness of resection, the operating time, the pelvic pain and complications., Results: The office hysteroscopic polypectomy was successfully performed in all 33 patients. The polyps ranged in size from 5 to 50 mm with a mean of 18.15 ± 11.45 mm. We analyzed the operating time with a mean of 11.45 ± 4.71 min: 29 procedures took less than 15 min from the start of vaginoscopy to the end of surgery. Overall mean visual analog scale (VAS) calculated was 2.48 ± 1.37 (range 0-6). The correlation between the size of the polyps and operating time was statistically significant (p < 0.001). No major complications were recorded., Conclusion: Our preliminary data demonstrated that can be possible to remove endometrial polyps by hysteroscopy, using the mini-resectoscope, in an office setting. All procedures were completed successfully and well tolerated with a little discomfort permitting the removal also of big sized polyps without a statistical correlation between VAS and size of polyps or operating time. The outpatient polypectomy is a less-costing procedure and represents an acceptable and effective alternative to inpatient resectoscopic polypectomy, leading to a complete polyp excision in nearly all patients.

Aim: To study somatization in a large sample of immigrants attending a first visit to a primary care service. Differences in somatization among four large immigrant groups (Europeans, Asians, South Americans, and Africans) and 16 subgroups based on nationality were assessed., Design: A total of 3105 patients were asked to participate in the study, of whom 3051 completed the 21-item version of the Bradford Somatic Inventory (BSI-21). Patients scoring 14 or higher on the BSI-21 were considered to be somatizers. A multiple logistic regression analysis adjusting for intervening variables tested the relative risk of somatization in and among the groups., Results: Among the 3051 patients who completed the BSI-21, 782 (25.6%) were somatizers. Somatizers were significantly more prevalent among South Americans (30.1%). After adjusting for covariates, Asians and Europeans, but not Africans, showed a significantly lower risk of somatization compared to South Americans. Among national subgroups, somatization occurred more frequently in Peruvians (32.9%). Compared to Peruvians, migrants from Eastern Europe, Morocco, the Philippines, Sri Lanka, and El Salvador demonstrated a significantly lower risk of somatization., Conclusions: Approximately one-fourth of socially disadvantaged immigrants who accessed primary care services used somatization to express their distress. However, the likelihood of somatization varied widely among the different groups, and was significantly higher in South Americans and in some African groups, and lower in some Asian groups.

Pain accompanying medical procedures can be considered in the "mind-body" problem of accounting for and describing the relationship between mental and physical processes (psyche and soma). Background/Objectives: The purpose of this study is to evaluate the severity of pain among patients undergoing a minihysteroscopy procedure under local anesthesia using the "GUBBINI SYSTEM" (GUBBINI Mini Hystero-Resectoscope; Tontarra Medizintechnik, Tuttlingen, Germany) and to assess the association of various covariates with pain during the procedure, including patient emotional state. Methods: This study included 171 patients admitted to the Center for Hysteroscopy under Local Anesthesia at the Heliodor Święcicki Gynecological and Obstetrical Clinical Hospital of the Karol Marcinkowski Medical University in Poznań, Poland, for hysteroscopic treatment under local anesthesia (paracervical, using lignocaine). The Center for Hysteroscopy is the first certified "CENTER OF EXCELLENCE" of The International Society for Gynecologic Endoscopy (ISGE) in Poland. Results: A positive relationship was observed between alexithymia and its trait of difficulty identifying emotions and pain, as well as between perceived pain and one of the deficits of emotional processing—signs of unprocessed emotion. Conclusions: In conclusion, before the hysteroscopy, adequate information and counseling related to the procedure can effectively reduce the pain and anxiety levels of the women, and nurses can navigate this stressful process. Providing education and counseling to all women undergoing hysteroscopy, and explaining the procedure in detail, should be the preferred approach. [ABSTRACT FROM AUTHOR]

The Authors after an overview on the most important causes of postsurgical adhesions, drove their attention to the tissue injury determined, during abdominal surgery, by exposure of pelvic serosa to the humidity of operating area. The AA tested body temperature in the Douglas pouch and under the liver on 30 patients who were operated by conservative surgery (myomectomy) and on 8 patient who underwent laparoscopy. A decrease of one degree in the Douglas pouch after one hour on the patient who had a Pfannestiel incision has been detected. While on the patients with longitudinal laparotomy no difference was evidenced. Serosal biopsies done at the beginning of surgery after pelvis exposure to the external conditions (temperature, humidity) showed a marked phlogosis in the tissue of the patients not treated at all. These tissue injuries were almost absent in the group treated with saline tissue irrigation and absent in the group that had parenteral prehydration, too. The AA suggested the use of the two techniques in conservative surgery in order to obtain in the open abdomen surgery results similar to those of the endoscopic one.

From 1984 to 1988, we corrected and prevented the prolapse of the vaginal vault of patients who wanted to maintain a satisfactory sexual function. This was done by adopting two different surgical techniques. The first, generally favored technique, was performed upon 179 patients and consisted of a colposuspension to the sacrospinous ligaments. The second technique, a colposacropexis, was performed upon 71 patients, in which abdominal associated pathologic changes required an abdominal surgical approach. Colposacropexis was performed, whenever possible, directly to the anterior longitudinal vertebral ligament or using synthetic materials (Mersilene [polyester fiber], Teflon [polytetrafluoroethylene] and Gore-Tex [expanded, reinforced polytetrafluoroethylene]). Both colposacropexis and vaginal suspension to sacrospinous ligaments have had comparable results in vaginal accommodation and long term fixation. Vaginal approach has a lower incidence of operative complications than the abdominal approach and seems to ensure a lower risk of recurrent cystocele, even if simple and asymptomatic.

Background: Hysteroscopy currently represents the gold standard for the diagnosis and treatment of intrauterine pathologies. Recent technological progress has enabled the integration of diagnostic and operative time, leading to the "see and treat" approach. Diode laser technology is emerging as one of the most innovative and intriguing techniques in this context. Methods: A comprehensive search of the literature was carried out on the main databases. Only original studies reporting the treatment of intrauterine pathologies using diode laser were deemed eligible for inclusion in this systematic review (PROSPERO ID: CRD42023485452). Results: Eight studies were included in the qualitative analysis for a total of 474 patients undergoing laser hysteroscopic surgery. Eighty-three patients had female genital tract abnormalities, 63 had submucosal leiomyomas, 327 had endometrial polyps, and one patient had a scar pregnancy. Except for leiomyomas, whose technique already included two surgical times at the beginning, only seven patients required a second surgical step. Cumulative rates of intraoperative and postoperative complications of 2.7% and 0.6%, respectively, were reported. Conclusions: Diode laser through "see and treat" hysteroscopy appears to be a safe and effective method. However, additional studies with larger sample sizes and improved designs are needed to consolidate the evidence currently available in the literature. [ABSTRACT FROM AUTHOR]

Purpose: This systematic review aims to comprehensively assess the safety and efficacy of transvaginal morcellation within an enclosed bag in gynecological surgeries, with a focus on its benefits, potential risks, and recommendations for its use., Methods: We conducted a comprehensive search of Epistemonikos, Web of Science, Medline (PubMed), Scopus, and Cochrane databases for studies on transvaginal contained morcellation in adult patients undergoing gynecological surgeries. The review included 22 studies that met the inclusion criteria, encompassing diverse surgical procedures, patient profiles, and outcomes. These studies were thoroughly reviewed and analyzed to assess the safety and efficacy of the morcellation technique., Results: Key findings from the selected studies indicate that transvaginal morcellation within an enclosed bag offers several advantages in gynecological surgeries, including reduced invasiveness, shorter operative times, and minimal blood loss when compared to conventional methods. The risk of tumor recurrence or dissemination appears to be low when appropriate precautions are taken, emphasizing the technique's safety, especially when performed by experienced surgical teams. While some studies reported complications, these were generally not directly associated with the morcellation technique., Conclusion: Transvaginal morcellation within an enclosed bag demonstrates potential as a safe and effective option for gynecological surgeries. The technique offers the benefits of minimally invasive procedures, including reduced bleeding, shorter recovery times, and improved cosmetic outcomes. This review also highlights the need for standardization in study methodologies and reporting, as the heterogeneity in outcomes across the selected studies poses challenges in drawing definitive conclusions., (© 2024.

Uterine fibromas are the most common benign uterine tumors. Although the majority of leiomyomas remain asymptomatic, they can cause serious clinical problems, including abnormal uterine bleeding, pelvic pain, and infertility, which require effective gynecological intervention. Depending on the symptoms as well as patients' preferences, various treatment options are available, such as medical therapy, non-invasive procedures, and surgical methods. Regardless of the extent of the surgery, the preferred option is the laparoscopic approach. To reduce the risk of spreading occult malignancy and myometrial cells associated with fragmentation of the specimen before its removal from the peritoneal cavity, special systems for laparoscopic contained morcellation have been developed. The aim of this review is to present the state-of-the-art contained morcellation. Different types of available retrieval bags are demonstrated. The advantages and difficulties associated with contained morcellation are described. The impact of retrieval bag usage on the course of surgery, as well as the effects of the learning curve, are discussed. The role of contained morcellation in the overall strategy to optimize patient safety is highlighted. [ABSTRACT FROM AUTHOR]

The therapeutic effect of estriol administered by the vaginal route on certain classes of symptoms relating to the climacteric has been assessed in 34 women. The response was generally very satisfactory both as regards neuropsychoendocrine disturbances and as regards urogenital dystrophic signs, in confirmation of the good absorption of the hormone and of its indifferent distribution in the target organs.

Endometrial polyps are one of the most common pathological conditions in gynecology. Hysteroscopy is the gold standard for the diagnosis and treatment of endometrial polyps. The purpose of this multicenter, retrospective study was to compare patients' pain perception during an operative hysteroscopic endometrial polypectomy in an outpatient setting with two different hysteroscopes (rigid and semirigid) and to identify some clinical and intraoperative characteristics that are related to worsening pain during the procedure. We included women that underwent, at the same time as an diagnostic hysteroscopy, the complete removal of an endometrial polyp (using the see-and-treat strategy) without any kind of analgesia. A total of 166 patients were enrolled, of which 102 patients underwent a polypectomy with a semirigid hysteroscope and 64 patients underwent the procedure with a rigid hysteroscope. No differences were found during the diagnostic step; on the contrary, after the operative procedure, a statistically significant greater degree of pain was reported when the semirigid hysteroscope was used. Cervical stenosis and menopausal status were risk factors for pain both in the diagnostic step and in the operative one. Our results confirm that operative hysteroscopic endometrial polypectomy in an outpatient setting is an effective, safe, and well-tolerated procedure and indicate that it might be better tolerated if a rigid rather than semirigid instrument is used.

Pain is a major barrier to successful outpatient hysteroscopy. Multiple factors can cause pain during the procedure including patient factors such as cervical stenosis and anxiety and procedural factors such as hysteroscope diameter and operative procedures. Pain relief strategies tailored to needs for Hong Kong women may enhance patient satisfaction and the success rate of outpatient hysteroscopic procedures. [ABSTRACT FROM AUTHOR]

Background: Vaginally assisted laparoscopic sacrocolpopexy (VALS) refers to the placement of synthetic meshes through the vagina in addition to traditional laparoscopic sacrocolpopexy. In this study, we aimed to investigate the medium- to long-term efficacy and safety of VALS for treating stage III–IV pelvic organ prolapse (POP). Methods: The study was designed as a case series at a single center. Patients with stage III–IV POP in our hospital from January 2010 to December 2018 were included. Perioperative parameters, objective and subjective outcomes, and complications were assessed. Results: A total of 106 patients completed the follow-up and were included in our study. Within a median follow-up duration of 35.4 months, the objective cure ratio of VALS reached 92.45% (98/106), and the subjective success rate was 99.06% (105/106). Patients reported significant improvements in subjective symptoms. In eight patients suffering anatomic prolapse recurrence, two posterior POP cases were treated by posterior pelvic reconstruction surgery, while six anterior POP cases did not need surgical therapies. The reoperation rate was 1.89% (2/106). No intraoperative complications occurred. Three patients (2.83%) had postoperative fever, and one (0.94%) had wound infection during hospitalization. Six patients (5.66%) had mesh exposure on the vaginal wall, and de novo urinary incontinence occurred in two patients (1.89%) during the follow-up period. Conclusion: VALS is an effective and safe surgical method for treating severe POP. Therefore, VALS should be considered in the treatment of severe POP due to its favorable subjective and objective outcomes, relatively low rate of infection and acceptable rate of mesh exposure.

Background: The main barriers to 'vulnerable migrants' receiving good quality primary care are language and administration barriers. Little is known about the experiences of healthcare discrimination faced by migrants from different cultural groups. The aim was to explore vulnerable migrants' perspectives on primary healthcare in a UK city. Methods: Three focus groups and two semi-structured interviews were aided by interpreters. These were analysed against a pre-developed framework based on national standards of care for vulnerable migrants. Recruitment was facilitated via a community organisation. Results: In total, 13 participants took part, six women and seven men. There were five Arabic speakers, four Farsi speakers and four English speakers. Themes included access to primary care, mental health, use of interpreters, post-migration stressors and cultural competency. Conclusion: Vulnerable migrants perceived high levels of discrimination and reported the value of a respectful attitude from health professionals. Appointment booking systems and re-ordering medication are key areas where language barriers cause the most disruption to patient care. Medication-only treatment plans have limitations for mental distress for this population. Community-based therapies which manage post-migration stressors are likely to enhance recovery.

In the context of the ever-increasing energy crisis, electrocatalytic water splitting has attracted widespread attention as an effective means to provide clean energy. However, the oxygen evolution reaction (OER), which is an important anodic half reaction, shows very slow kinetics due to the multi-step electron transfer process, which severely restricts the efficiency of energy conversion. Herein, we used a simple solvothermal method to dope iron into the cobalt-containing hydroxide precursor, and successfully prepared the Fe-doped Co-oxide electrocatalyst Co3−xFexO4-0.01. It only needs an overpotential of 294 mV to perform the OER at a current density of 10 mA cm−2, and has a low Tafel slope of 47.3 mV dec−1. Moreover, Co3−xFexO4-0.01 has excellent stability. There is no significant increase in the overpotential for oxygen evolution at a current density of 10 mA cm−2 after nearly 20 h. BET surface area test and XPS spectroscopy results show that Fe doping provides more mesopores and oxygen bridges, which is conducive to the construction of active sites and electronic regulation during the OER. This work can help design more bimetallic based highly active OER materials. [ABSTRACT FROM AUTHOR]

The essay is dedicated to the late stage of career of Pietro Bianchi, painter from Como who died in Rome in 1732. The unpublished documents (his will, the inventory of lost collection in his apartment in Palazzo di Spagna in Rome, and other documentary evidences) allow identifying the artist as "il Bustino", the adopted son and pupil of Antonio Crespi Castoldi, and painter in Lombardia in late XVII siecle and the beginning of XVIII siecle. This contribution offers the opportunity to understand his role as an agent and as a painter for the Spanish and Potuguese Crowns and help understanding his relationship with Odescalchi family and with the cardinal and ambassador Francesco Acquaviva.

Purpose: This study aimed to address knowledge gaps about post-traumatic stress disorder (PTSD) in mid-age and older adults, with particular attention to the relationship of PTSD with nutrition and with ethnicity and immigrant status. Methods: Binary logistic regression analysis of weighted comprehensive cohort data from the baseline Canadian Longitudinal Study on Aging (CLSA; n = 27,211) was conducted using the four-item Primary Care-PTSD tool (outcome) and immigrant status by ethnicity (Canadian-born white, Canadian-born minority, immigrant white, immigrant minority). Covariates included various social, economic, nutrition and health-related variables. Results: After controlling for socioeconomic and health variables, immigrants from minority groups had significantly higher odds of PTSD compared to their Canadian-born counterparts, whereas white immigrants had lower odds of PTSD. These relationships were significantly robust across seven cluster-based regression models. After adjusting for ethnicity/immigrant status, the odds of PTSD were higher among those earning lower household incomes, widowed, divorced, or separated respondents, ever smokers, and those who had multi-morbidities, chronic pain, high nutritional risk, or who reported daily consumptions of pastries, pulses and nuts, or chocolate. Conversely, those 55 years and over, who had high waist-to-height ratio, or who consumed 2–3 fiber sources daily had significantly lower odds of PTSD. Conclusion: Interventions aimed at managing PTSD in mid-age and older adults should consider ethnicity, immigrant status, as well as socioeconomic, health, and nutrition status.

Background: Previous studies have already proven high rates of common mental disorders in Syrian refugees. Nevertheless, little is known about the patterns of somatic distress among this refugee population. For this reason, we aimed to examine the prevalence, co-occurrence, and risk factors of somatic distress among Syrian refugees in Germany.Methods: This study analyzes the second measurement point (N = 116) of a prospective register-based survey among 200 adult Syrian refugees with residence permission in Germany. The survey consisted of information on sociodemographic and migration-specific characteristics, health care utilization, traumatic life events, acculturative stress (Barcelona Immigration Stress Scale (BISS); subscales: perceived discrimination, intercultural contact stress, homesickness, and general psychosocial stress), and self-reported outcomes of somatic distress (Patient Health Questionnaire (PHQ-15)), depression (PHQ-9), generalized anxiety disorder (GAD-7), and post-traumatic symptoms (Essen Trauma Inventory (ETI)).Results: Almost half of the respondents (49.1%) were identified as being at risk of somatic distress (PHQ-15 score ≥ 6), and even 24.1% being bothered by moderate-to-severe levels of somatic distress (PHQ-15 score ≥ 10). The most robust associations with somatic distress were found for female gender, the amount of health care utilization, multiple trauma exposures, general psychosocial stress, and self-reported depression and anxiety symptoms. High comorbidities with somatic distress were shown for all of the common mental disorders studied.Conclusions: The presented study reveals a significant risk of somatic distress among this displaced population and highlights implications for policy and health care providers.

Catalysts for heterogeneous catalytic reactions, particularly for total water splitting, is receiving tremendous attention and sustainable fuel development is highly relied on the catalysts development, where both the material and its method of preparation are important. Here, bimetallic multi‐phasic catalysts containing nickel (Ni) and iron (Fe) are synthesized using a simple but reproducible polyol method, which results in to different sponges having control over their chemical stoichiometry. The macroporous sponges thus developed contain metallic Ni, NiO, and Fe2O3, where their proportionate content can be varied with initial precursor ratio. The NiFe15 so developed is having the best oxygen evolution performance in terms of overpotential, kinetics, and charge transfer properties, and it is found to be better than the benchmarked IrO2 based catalysts. The hydrogen evolution from the other ratio, NiFe5, is found to be better than other Ni and Fe based samples, and it is found to be very close to the hydrogen evolution performance of platinum. An alkaline water electrolysis full cell is constructed, devoid of any precious metals but with NiFe5 and NiFe15, and the overall splitting potential for the benchmarked current density of 10 mAcm−2 is found to be 1.62 V only, which is better or on par with the other singly/multi‐phasic systems reported so far. Hence the work presented here shows the possibilities of futuristic electrochemical technologies with viable catalysts, and a detailed study is presented. [ABSTRACT FROM AUTHOR]

Exploring high-performance and stable electrocatalysts for the oxygen evolution reaction (OER) is critical for the conversion and storage of renewable energy. Herein, a novel strategy was developed for the construction of dispersive nickel phosphide (Ni2P) embedded in two-dimensional (2D) amorphous alumina arrays on three-dimensional (3D) nickel foam (NiP–Al2O3/NF) electrocatalysts via the reduction of a layered double hydroxide (LDH) precursor. Owing to its unique 3D nano/micro-architecture, multi-porous structure, interconnected conductive skeleton, and highly dispersive Ni2P active sites, the NiP–Al2O3/NF electrocatalyst exhibited excellent OER activity with overpotential as low as 193 mV at 10 mA cm−2 in a 1.0 M KOH solution and superior catalytic activity for the oxidation of 5-hydroxymethylfurfural in alkaline media. Density functional theory calculations demonstrated that the introduction of P to Ni could effectively reduce the OER overpotential. Furthermore, benefiting from the flexibility of compositional tailoring of both the brucite-like layers and interlayer anions of LDHs, the synthesis strategy presented here can be easily extended to the fabrication of various nanostructured noble-metal-free functional materials, which are expected to have wide application prospects in many domains, especially in catalysis.

Background: Somatic and psychopathological conditions (e.g., anxiety, depression, post-traumatic stress disorder, and somatization) are frequent among immigrants belonging to various ethnic groups. Worldwide findings on the epidemiology regarding specific mental conditions still vary with respect to different migration samples and migration contexts. This inconsistency also holds true in the incidence of somatization among migrants. We carried out a systematic review analyzing the relationship between migration and somatization by providing a qualitative data synthesis of original research articles on the topic. Methods: According to PRISMA guidelines, we conducted a systematic search of the literature on PubMed, Scopus, ISI Web of Science, PsycINFO, Google Scholar, and ScienceDirect. The articles were selected using multiple combinations of relevant search terms (e.g., defined somatization and related disorders, and migration status). Each database was searched systematically from January 2000 to December 2017. Results: The initial search identified 338 records, of which 42 research reports met the predefined inclusion criteria and were analyzed. Most studies (n = 38; 90%) were cross-sectional. The main findings of this study are that migrants with somatization exhibited more psychological distress, had an increased perceived need for healthcare service utilization, and reported more post-migration living difficulties and/or post-traumatic stress disorder than those without somatization. It was also found that specific individual features mediate the association between somatization and migration. The prevalence and correlates of somatization were found to vary across the immigrant groups, depending on cultural variation in reasons for migration, stress exposure, explanatory models of illness, coping, and other individual variables. Conclusion: Somatization is a challenge for health professionals due to its vague nature. In this regard, clinical management of immigrant patients should include further efforts to address emotional distress, with special attention to social, cultural, and linguistic differences.

This work aims to illustrate the importance of selecting the best substrate and ‘powder to electrodes’ fabrication technique when screening new OER catalysts. A well-established water oxidation catalyst, RuO2 powder is used to fabricate different types of commonly used electrodes found in literature including: dropcast electrodes, doctor-blade electrodes and pressed electrodes. A variety of support substrates are used based on materials such as platinum, titanium, nickel and glassy carbon. Additionally, a variety of substrate geometries are also investigated, including: discs, foils and foams. The results show that the OER activity of the RuO2 powder is significantly varied depending on the electrode fabrication and substrate combination utilised. These findings show the importance of screening different substrates and fabrication methods when investigating the OER with new powder materials. [ABSTRACT FROM AUTHOR]

The present research evaluated the psychosocial health and quality of life of North African (NA) immigrant women living in Italy. A survey of 205 NA-born and Italian-born women was carried out. Psychosocial, sociodemographic and migration data were collected. Anthropometric indices were computed by direct measurements of height, weight, waist and hip circumferences. Multivariate analysis showed that the main explanatory variable for all dimensions of psychosocial status was the migrant status. Other explanatory variables were educational level and number of children for psychological discomfort, and weight status for well-being, quality of life and stress. Anthropometric indices were explanatory variables for quality of life. In conclusion, this study provides further evidence of higher psychological stress and discomfort and lower well-being and quality of life in immigrant women. Public social support is necessary to control, maintain and improve the mental health outcomes of immigrant communities in the host country. [ABSTRACT FROM AUTHOR]
