Rubella is the most important preventable cause of fetal malformations. Infection during pregnancy can result in fetal growth restriction, miscarriage, fetal death or it can cause congenital rubella syndrome with visual, auditory and cardiac defects. There are still many developping countries which are endemic for Rubella, despite major vaccination programmes available worldwide. There are no clinical symptoms present in approximately one half of cases, so diagnosis relies on serological testing if infection is suspected. Detection of IgM specific antibodies is the method of choice for diagnosis of both postnatal and congenital rubella. It has high sensitivity, but false positive cases are always possible after infection with other viruses like parvovirus B19, Epstein-Barr virus, cytomegalovirus and measles. Prevention relies on preconception care when it is recommended to check the immunity status for rubella (IgG) and for non-immunized patients, vaccination should be indicated.

Usually gastrointestinal discomfort is a very common complaint and most of the time it’s easy to manage in daily pharmaceutical practice. But some conditions can lead to further complications or become worse over time, so it’s really important that patients can access advice and support when they need it. Pharmacists are in the position to guide the selection of the best treatment by confirming the diagnosis, sending patients with alarm symptoms to physicians and educating patients on the proper use of their OTC medication. Gastrointestinal symptoms such as diarrhea and nausea/vomiting are often recognized among the patients with COVID-19. The impact of pharmacist intervention is needed in order to ensure reliable information for preventing, detecting, treating and managing coronavirus infection.

Colonic diverticular disease consists in the presence of several diverticula in the colon. A diverticulum is a sac-like bag of varying sizes, resulting from hernias of the colonic mucosa outside the lumen. At the level of the digestive tract diverticula are most frequently found in the sigmoid colon. This pathology is rarely found in young people, so it is not considered when making a differential diagnosis in pregnant women with abdominal pain. This article will present two case reports of diverticulitis in pregnancy, published in the literature, as well as their diagnosis and management.

One of the most common surgical entities, globally, is hernia. Even though it affects female population less often than men and its occurrence is rather exceptional during pregnancy, it must not be neglected, especially due to the difficulties in diagnosing this entity correctly in the gestation period. We conducted a review article based on data from 13 papers published between 2015 and 2021 which assessed the challenge of hernia diagnosis during pregnancy, available and recommended investigations for a proper diagnosis, potential complications that hernia might cause in pregnant patients, the appropriate treatment during pregnancy and the ideal moment for surgery, if necessary. It appears to be widely acknowledged that it is best to uphold surgical repair of hernia until after delivery. Nevertheless, there is no clinical guideline available on this matter and the existing studies are either case-reports or have used rather small group of patients, therefore future studies are of utmost necessity.
ADVICE: Optimizing meetings, a critical post-pandemic task for physician leaders
Authors: Johnston Aaron
Published: May 2022

Meetings and committees occupy a significant amount of the working time of physician leaders and their teams. The amount of time spent in meetings has grown over decades and that growth has rapidly accelerated over the COVID-19 pandemic. The return to in-person work offers physician leaders the opportunity to optimize their meetings by thinking about the entire suite of meetings they and their teams are involved in. Creating a meeting inventory and evaluating it can reveal patterns, inefficiencies, and redundancies that can become targets for optimization. Effective meetings can create a competitive advantage for leaders, teams, and organizations and can support productivity and job satisfaction. Meeting optimization should be a high priority for physician leaders.

We recently finished weeks of service in different intensive care units (ICUs) on opposite sides of the Canadian Rockies. Neither of us had the most crushing of weeks, but we both experienced sadness and exhaustion in ways that come from long hours coupled with tragedy for many, and the end of life for some. For too long, we had avoided frank discussions about our work environment and what drives us to work in the place we do and in the way we do.
Cost-effectiveness Analysis of Еarly Medical Rehabilitation of Patients with Cerebral Stroke

Published: May 2022

Carrying out resuscitation procedures in the intensive care unit (ICU) aimed at maintaining and restoring the patient’s vital functions, the use of specialized resuscitation equipment and bed rest simultaneously lead to aggravation of the patient’s condition. The consequences of being in the ICU may also include the development of the post-intensive care syndrome (PIT syndrome), the prevention of which is the main goal of early rehabilitation with the participation of the multidisciplinary rehabilitation team of specialists (MDRT) led by a physical and rehabilitation medicine physician. Specialized medical rehabilitation carried out by MDRT is extremely beneficial for all neurological conditions, resulting in substantial savings in ongoing care costs, especially for ICU patients. The foreign and domestic research experience indicates a reduction in healthcare costs when introducing early rehabilitation in the ICU by reducing the duration of the patient’s stay in the expensive round-the-clock bed and lowering the patient’s home care costs or continuing rehabilitation activities at the second and third stages, as well as saving precious time for effective recovery of the developed functional deficits. It may seem that rehabilitation in the ICU with the participation of MDRT is more expensive than the work of one department doctor and a nurse. However, this article provides evidence of the economic efficiency of the MDRT work on the analysis of the results of the pilot project “Development of the Medical Rehabilitation System in the Russian Federation”, as well as the analysis of clinical cases of the Federal Center of Brain Research and Neurotechnologies of the Federal Medical Biological Agency of Russia. So, in the absence of early rehabilitation in the ICU, the patient’s stay is delayed and the number of re-hospitalizations to the unit increases. Thus, the results of early medical rehabilitation will have a direct impact on reducing the costs associated with bed-days reducing, providing patient’s care, changing the working life of relatives, pensions of patients and their caregivers.

The use of adaptive physical culture in the system of complex rehabilitation of patients with cerebral palsy (CP) is becoming more popular. Adaptive climbing (AC) is one of these types of physical culture and sports activities. Currently, there are not many data in the domestic and world literature devoted to the study of the AC use in the complex rehabilitation of patients with CP.
Aim. Evaluation of the effectiveness and safety of AC in the rehabilitation of children and adolescents with spastic forms of CP in addition to conventional medical rehabilitation.
Material and methods. The study included 30 patients aged from 5 to 18 years with spastic forms of CP who were allocated into one of two groups: the 1st group, the study group (n=15) — patients who underwent standard medical rehabilitation and AC classes; the 2nd group, the control group (n=15) — participants who received only medical rehabilitation. A comprehensive assessment of the rehabilitation measures effectiveness and safety was performed before the start of AC classes and after 3 months using clinical neurological and instrumental examinations, including biomechanical examination (electropodography, video analysis of walking and stabilography).
Results. Group 1 patients showed a statistically significant improvement in general motor functions on the GMFM-88 scale (p=0,0001), a decrease in the level of spasticity on the мodified Ashworth scale (p=0,0051) and an improvement in manual abilities on the MACS scale (p=0,0431) 3 months after inclusion in the study. Positive dynamics in the form of an increase in the symmetry of step time (p=0,0063), step length (p=0,0083) and step velocity (p=0,0409) were noted according to the electropodographic study in the 1st group. A statistically significant increase in the range of motion in the hip (p=0,0038) and knee joints (p=0,0076) was detected in the 1st group according to video analysis of walking. There was no significant change in the indicators in the 2nd group, except for the severity of spasticity on the modified Ashworth scale (p=0,0180). A positive correlation was found between the indicators “step length” and “ step velocity” (r=0,605, p=0,0168). A negative correlation was found between the “step velocity “ indicator and the GMFCS score (r= – 0.832, p=0,0372). Only 2 adverse events were registered in the study group: acute respiratory viral infection and wrist injury during AC.
Conclusion. AC, in addition to traditional methods of medical rehabilitation, leads to a decrease in spasticity, increased joint mobility and control of voluntary movements, improved maintenance of the body position, walking and precise hand movements, and also has a favorable safety profile. AC is an effective and safe motivating method of physical culture that can change the patient’s view on traditional therapy.

Published: May 2022

The COVID-19 pandemic has created increasing uncertainty among companies and investors. As a result, it is necessary to investigate the behaviour of stock exchange mechanisms during the crisis generated by a virus. The purpose of the research is to determine the link between, the increase of the volatility of the shares on the Bucharest Stock Exchange and the specific stock market indicators during the COVID-19 pandemic. The dependent variables were standard deviation and simple moving average, and the variables considered were: PER, P/BV, EPS, DIVY, stock market capitalization and free-float. Data were collected regarding all the shares listed on the Bucharest Stock Exchange between 01.01.2020 and 01.03.2021. The study consists of two econometric models that allowed the identification of the links between the variables. The results obtained show that during the pandemic generated by Covid-19 the volatil-ity of the shares is not dependent on the variables considered. Of all the variables, only EPS has a statistically significant influence.

The crisis caused by the spread of the COVID-19 virus has affected companies listed on the stock exchange differently. While some actions have not been affected by the pandemic, others have declined sharply. Based on such a hypothesis, the objective of the research is to determine the extent to which the shares of companies listed on the Bucharest Stock Exchange were affected by the COVID-19 pandemic. The analysis period is between 01.01.2020 and 01.03.2021. For the shares that registered reductions of the market price, the period in which they reached the mini-mum value was established. Next, the average period was established in which their exchange rate returned to the value of January 2020. The research followed the dynamics of the listed shares from the point of view of the activity carried out and a ranking of them was made.

Authors: Vosyliute Ieva , Maknickiene Nijole
Published: May 2022

Due to increasing technical capabilities, financial fraud becomes more sophisticated and more difficult to detect. As there are various categories and typologies of financial fraud, different detection techniques may be applied. However, based on the data generated daily by financial organizations, a technical solution must be implemented. This paper presents a comprehensive literature review of financial fraud, the categorizations of financial fraud, and financial fraud detection with the particular focus on computational intelligence-based techniques. As outlined in the reviewed literature, money laundering is a multilayered crime involving several fraud typologies; therefore, it was selected to be analysed in this research. The purpose of the research is to investigate the synthetic dataset of the money laundering scheme to see whether additional patterns could be outlined, which would help financial organizations to recognize suspicious activity easier. To achieve this goal, computational intelligence - decision tree, was selected as a classification method to identify additional patterns. As a result, data classification provides new data parameters which are essential in improving accurate and efficient financial fraud detection.

Authors: Santamaría-Aguilar Daniel , Lagomarsino Laura P.
Published: May 2022

With about 70 species Virola, is the largest genus of Myristicaceae in the Neotropics, the genus ranked in the top ten genera of abundance across Amazonia. Ten new species are proposed in this striking genus, which are described based on morphology, and are illustrated. The new species were discovered thanks to herbarium specimens collected mainly in the 1980s and 1990s when field documentations were more active. The new species come from Colombia (V. calimensissp. nov., V. cogolloisp. nov., V. excisasp. nov., V. tuckeraesp. nov.), Ecuador (V. alvaropereziisp. nov., V. bombuscaroensissp. nov., V. calimensis, V. excisa, V. yasunianasp. nov.), Peru (V. aguarunanasp. nov., V. cumalasp. nov., V. excisa, V. parkerisp. nov.), and Brazil (V. excisa, V. yasuniana). Additionally, a lectotype is designated for V. macrocarpa, a name used to identify some specimens of the new species here described, and V. kwatae is reported for the first time for Brazil. We provide a comparation table between the new species and the species that is morphologically close to it, a preliminary list of species for the genus, and notes of how the new species were treated in floras, checklists, or collections that need more study and herbarium specimens.

Published: May 2022

In an earlier molecular phylogenetic study, a sample of what was originally identified as Cryptantha hispida (Boraginaceae) from Chile, grouped with species of the genus Johnstonella. This sample was subsequently shown not to be C. hispida, but an undescribed species, endemic to the dry Puna of Chile. This new species is described here as Johnstonella punensis, along with a key to all South American species of the genus. Johnstonella punensis resembles other members of that genus in having an ovate fruit shape, ovate nutlets and a long style that extends beyond the nutlets. It is unusual in the genus in having a non-tuberculate, dimpled to rugulose nutlet surface sculpturing. Its closest relative within the genus is likely the South American J. diplotricha.
Uniqueness of the partial travel time representation of a compact Riemannian manifold with strictly convex boundary
Authors: Pavlechko Ella , Saksala Teemu
Published: May 2022

In this paper a compact Riemannian manifold with strictly convex boundary is reconstructed from its partial travel time data. This data assumes that an open measurement region on the boundary is given, and that for every point in the manifold, the respective distance function to the points on the measurement region is known. This geometric inverse problem has many connections to seismology, in particular to microseismicity. The reconstruction is based on embedding the manifold in a function space. This requires the differentiation of the distance functions. Therefore this paper also studies some global regularity properties of the distance function on a compact Riemannian manifold with strictly convex boundary.
Variance-constrained robust $ H_{\infty} $ state estimation for discrete time-varying uncertain neural networks with uniform quantization
Authors: Sun Baoyan , Hu Jun , Gao Yan
Published: May 2022

In this paper, we consider the robust $ H_{\infty} $ state estimation (SE) problem for a class of discrete time-varying uncertain neural networks (DTVUNNs) with uniform quantization and time-delay under variance constraints. In order to reflect the actual situation for the dynamic system, the constant time-delay is considered. In addition, the measurement output is first quantized by a uniform quantizer and then transmitted through a communication channel. The main purpose is to design a time-varying finite-horizon state estimator such that, for both the uniform quantization and time-delay, some sufficient criteria are obtained for the estimation error (EE) system to satisfy the error variance boundedness and the $ H_{\infty} $ performance constraint. With the help of stochastic analysis technique, a new $ H_{\infty} $ SE algorithm without resorting the augmentation method is proposed for DTVUNNs with uniform quantization. Finally, a simulation example is given to illustrate the feasibility and validity of the proposed variance-constrained robust $ H_{\infty} $ SE method.
Effect of Sr and Ni Addition on Microstructure, Tensile Behavior and Electrical Conductivity of Squeeze Cast Al-6Si-3Cu Al Alloy
Authors: Li Yu Xian , Fu Yin Tian , Hu Anita , Nie Xueyuan , Hu Henry
Published: May 2022

Mechanical strengths and electrical conductivity are the very important engineering properties of lightweight aluminum (Al) alloys used in automobiles, especially for battery-powered electric vehicles (BEV). However, the main issue is that the mechanical properties and the electrical conductivity of Al alloys are mutually exclusive. This study aims to simultaneously improve both the tensile properties and the electrical conductivity of the squeeze as-cast Al-6wt% Si-3wt% Cu by modifying its microstructure with the addition of nickel (Ni) and strontium (Sr). In comparison to those of the alloy free of Sr and Ni, the additions of 0.03 wt.% Sr and 0.5 wt.% Ni in the Al-6Si-3Cu alloy significantly improved the ultimate tensile strength, yield strength and electrical conductivity. This was because the addition of Ni element, as a transition element, collaborated with Cu to form fine intermetallic Al-Cu-Ni phases for dispersion strengthening. Also, the modification of the Si morphology from micron needles to nanoparticles by the Sr addition enhanced both the strengths and electrical conductivity of the developed alloy.

Published: May 2022

Grain characteristics are one of the most important factors in determining alloy properties. Thermal deformation and solution treatment experiments were used to investigate the evolution of grain features and mechanical properties of Al-9.39 Zn-1.92 Mg-1.98 Cu alloy. The results reveal that when the deformation temperature rises, the recrystallized grain size, recrystallization fraction, and sub-grain size for the alloy's final microstructure gradually increase. The recrystallized grain size and fraction increase as the solution temperature rises, although the sub-grain size of the final microstructure of the corresponding alloy changes slightly. Fitting is used to deriving the function of recrystallization size, recrystallization fraction, and sub-grain size as a function of deformation temperature. The tensile properties of the alloy at T6 state are the best after deformation at 400°C and solution treatment at 470°C. The brittle fracture mode is shown in recrystallized grains, whereas the toughness fracture mode is shown in sub-grains.

The microstructures of as-cast and homogenized Al-Cu-Mg-Ag alloys with 1.98, 3.66 and 5.16 wt.% Cu contents (Alloy 1, Alloy 2, Alloy 3, respectively) were investigated by scanning electron microscope (SEM), energy dispersive spectroscopy (EDS), differential scanning calorimetry (DSC), X-ray diffraction (XRD) and calculation of phase diagram. The results indicate that the second phases in the as-cast alloys consist of θ (Al2Cu), ternary α (Al)-θ (Al2Cu)-S(Al2CuMg) eutectic and Fe-enriched phase. The invariant reactions are L→α (Al) + θ (Al2Cu) at 542°C and L→α (Al) + θ (Al2Cu) + S(Al2CuMg) at 505°C during solidification. An increase of Cu content promotes the formation of θ (Al2Cu) phase, therefore leading to the total second phases increasing in the as-cast alloys. The ternary eutectic completely dissolves into the matrix after the first-step homogenization at 490°C, and θ (Al2Cu) phase dissolves subsequently after the second-step homogenization at 510°C. It is suggested that the proper homogenization treatments are 490°C/24 h for Alloy 1, 490°C/24 h + 510°C/24 h for Alloy 2 and 490°C/24 h + 510°C/48 h for Alloy 3.

Anatomical variations of the renal vasculature and outcome of live donor nephrectomies: experience of a single surgeon
Authors: Arudchelvam Joel , Laksiri Waruna
Published: May 2022

IntroductionRenal artery [RA] variations occur in 18 % to 21%. Variations determine the side selection in kidney donors and the outcome of Kidney Transplantation. This series reports the renal vascular anatomy [RVAS] variations and associated complications encountered during live donor nephrectomies [LDN].Methods Consecutive LDN done by a single surgeon is included, the patient's demography, LDN side, RVAS variations and complications are recorded. The kidney with worse function and the least number of RA is selected for LDN. The RVAS is assessed by Computed Tomography Angiography and intra-operatively. Single RA and vein with the hilar division are considered normal anatomy.  Results 159 were included with 103 [64.8%] males. The mean age was 38.2 years [23-63]. 106 [66.7%] were left LDN. 136 [85.5%] had single RA of these 34 [21.4%] had early-branching [EB]. 23 [14.5%] had multiple RA [2 in 21 and 3 in 2]. Therefore variations occurred in 35.8 %. In a subgroup analysis of 123 renal veins, only 6 [6.8%] with single RA but 9 [25.7%] out of 35 with multiple arteries or EB arteries had multiple veins. This difference was statistically significant [p-0.004]. 11 [6.9%] had complications [3 renal bed haematoma]. 2 of 3 haematoma patients had EB of RA [5.9% vs. 0.8%] and underwent right LDN [3.8% vs. 0.9% / p>0.05].Conclusions RA variations occur in 35.8 %. Multiple arteries and EB is significantly associated with multiple veins. The complication rates in patients with EB appear to be high. However, this was not statistically significant probably due to low numbers.

IntroductionPatient satisfaction is one of the benchmarks by which the quality of health care services is evaluated. The objective of this study was to assess the patients' satisfaction with services delivered at the urology outpatient clinic of Colombo South Teaching Hospital (CSTH), Sri Lanka.MethodA descriptive cross-sectional study was done over three months (1.12.2019 – 28.2.2020) at the urology outpatient clinic of a tertiary care hospital in Sri Lanka. A pre-tested, self-administered questionnaire based on the SERVQUAL questionnaire was used to collect data. Seven questions were based on demography and eighteen were aimed at assessing responsiveness, tangibles, empathy and reliability. The Likert scale was used to determine the level of satisfaction.ResultsThe study sample constituted of 220 patients. Nearly one third (32%) of them felt the waiting time to be registered at the clinic and to meet a doctor were too long. More than half (59%) said the clinic was overcrowded. However, over 90% of the patients perceived that staff characteristics, laboratory services and waiting time from the date of referral to the clinic appointment were satisfactory. Nearly 93% of the participants would recommend the clinic to a friend or a relative for seeking treatment.Conclusions Although patient satisfaction was good in many domains, by developing a better mechanism of giving appointments spread throughout the clinic, patient satisfaction and the quality of services provided at the urology outpatient clinic can be improved further.

IntroductionMini PCNL was developed with the use of 15 - 18 F sheaths (instead of the conventional 24 - 30 F) to reduce morbidity that is seen in standard PCNL. Performing mPCNL in the supine position further adds to its many advantages including shorter operative time. This largest series evaluates the overall benefits observed in patients undergoing supine mPCNL for the treatment of renal stones in Sri Lanka.Material and methodsFive hundred and five patients with renal and/or upper ureteric stones (in 509 kidneys) who underwent mPCNL between January 2016 - December 2020 were studied. Radiological evaluation was performed by CT scan. Holmium: YAG laser was used for stone fragmentation using a 12F nephroscope through 15 Amplatz sheath under fluoroscopic guidance. Patients clinical and treatment outcomes were evaluated in terms of stone-free rate, operative time, hospital stay and complications.ResultsMean age was 48.85 years (14-80). There was a male preponderance. The majority (92.3%) being ASA I and II. The mean BMI was 25.32kgm-2 of whom 42.2% were overweight and 16.8% were obese. The mean stone diameter was 24.5 mm(9-45mm) and density1064Hu. The majority of stones (57.3%) had a GUYS score I while 13.4% were complete staghorn. The predominant approach was a single tract, subcostal lower pole puncture. However, multitrack PCNL was performed in 38(7.5%) patients. The complete stone-free rate achieved was 84.1%. Mean operative time was 87 min while the median hospital stay was 4 days. The overall complication rate was 21.5%(n=109), the majority of which being Clavien Dindo class I. No deaths, renal loss or conversion to open surgery were observed. DiscussionMini-PCNL in supine position should be considered more often for renal stone management in Sri Lanka not only due to its wide safety margin and effectiveness but also because of its rapid turnover time.

Çin’de Aralık 2019’da görülen ve ardından pandemi olarak ilan edilen Coronavirus (COVID-19) enfeksiyonun her yaş grubunda etkili olduğu görülmektedir. Ancak yenidoğanlar bağışıklık sistemlerinin gelişmemiş olması, maternal vertikal geçiş olasılığı, vajinal doğumlarda perinatal temas olasılığı ve şüpheli enfekte anne ile doğumdan sonra yakın temas nedeniyle yüksek risk grubundadır. Bu durum yenidoğanlara yaklaşımın nasıl olacağı ve emzirmenin güvenli olup olmadığı gibi sorunları beraberinde getirmiştir. COVID-19’lu gebeler ve yenidoğanlar ile ilgili mevcut veriler sınırlıdır. Çalışma alanlarında gebe ve yenidoğanlara hizmet sunan ebelerin bu enfeksiyon varlığında yenidoğan bakımında nasıl bir yol izleyeceklerini bilmeleri önemlidir. Bu makale literatür ışığında yenidoğan ve gebelerde COVID-19 enfeksiyonu yönetimi hakkında güncel bilgiler sunmayı amaçlamıştır.

Artan obezite prevalansına paralel olarak non alkolik yağlı karaciğer hastalığı birçok ülkede en yaygın karaciğer hastalığı haline gelmiştir. Non alkolik yağlı karaciğer hastalığı kardiyovasküler, hepatik, metabolik ve onkolojik sekellerinin yanı sıra karaciğer naklinin önde gelen nedeni haline geldiği için dünya çapında önemli bir morbidite ve mortalite nedenidir. Bu salgın ve sonuçları, dünyanın dört bir yanından uzmanları, hastalığın yönetimi ve tedavisi için etkili stratejiler belirlemeye yönlendirmiştir. Şu anda non alkolik yağlı karaciğer hastalığı için onaylanmış bir ilaç tedavisi yoktur. Bu nedenle diyet ve egzersiz gibi değiştirilebilir risk faktörleri hastalığın yönetimi ve tedavisinde köşe taşı olarak yerini korumaktadır. Vitaminler sağlıklı yaşam için hayati önem taşıyan mikro besin öğeleridir. Bazı çalışmalar yağlı karaciğer hastalığını vitamin eksiklikleri ile ilişkilendirse de bu ilişkilerin altında yatan mekanizma tam olarak aydınlatılamamıştır. Bu nedenle, bu derleme, vitaminlerin non alkolik yağlı karaciğer hastalığı patogenezindeki rolünü tartışmayı ve hastalık yönetiminde potansiyel faydalarını araştırmayı amaçlamaktadır.

Sağlık hizmetlerinde farklı alanlarda uzmanlığa sahip birçok kişi bir arada çalışmaktadır. Sağlık hizmetlerinin en önemli üyelerinden olan hemşireler hastalara kaliteli, güvenli ve 7/24 kesintisiz bakım sağlamaktadır. Son yirmi yılda hasta bakımı giderek daha karmaşık hale gelmiştir. Bir hastanın durumunun karmaşık olması da daha yoğun hemşirelik bakımını gerektirmektedir. Hastalara yoğun bir şekilde bakım verilmesi için mesleki işbirliğine ihtiyaç duyulmaktadır. Nüfusun yaşlanması, kronik hastalıkların artması, bakım uygulamalarında çeşitlilik, hemşirelik bakım alanları içinde uzmanlaşma, kalite standartları gibi güncel gelişmeler de mesleki işbirliği gereksinimini artmaktadır. Mesleki işbirliğinin sağlanmasında bireysel ve kurumsal pek çok faktör etkili olmaktadır. Bu faktörlerin incelenmesi ve önerilen uygulamaların iş yaşamına aktarılması hemşireler arası mesleki işbirliğini artırmada yararlı olacaktır. Hemşireler arası mesleki işbirliği arttırılması ile de hastalara sunulan bakımın kalitesinin artacağı ve güvenli hasta bakımının sağlanacağı düşünülmektedir. Bu nedenle bu derleme hemşireler arası mesleki işbirliğini artırmaya yönelik hazırlanan Ontario hemşireler derneği tarafından 2016 yılında güncellenen kanıta dayalı uygulamaları incelemek amacıyla yapılmıştır.

Published: May 2022

Amaç: Perinatal bakım almanın obstetrik sonuçları etkilediği bilinmektedir. Göç eden kadınlar bazı faktörler sebebiyle bakıma erişememektedir. Bu derlemenin amacı göç eden kadınların perinatal dönemde bakım almasını etkileyen faktörlerin belirlenmesidir.Yöntem: Derleme kapsamına alınan çalışmaların dahil edilme kriteri olarak; göçmen kadınların perinatal bakım sonucunu içeren çalışma olması, araştırma deseninin nitel ve/veya nicel olması, İngilizce dilinde yayınlanması, son beş yılda yayınlanan araştırma olması ve tam metnine ulaşılabilen çalışma olmasıdır. Literatür taraması sonucunda 17 çalışma araştırmaya dahil edilmiştir.Bulgular: Bu çalışmadan elde edilen bulgular; dil engeli, sosyoekonomik durum, göçmen statüsü, sağlık sistemine yabancı olma, ayrımcılık ve damgalanma, ulaşım engelleri ve yabancı çevre, sosyal desteğin olmaması ve diğer faktörler şeklinde alt başlıklar halinde sunulmuştur. Göçmen kadınların en çok dil problemi yaşadıkları tespit edilmiştir.Sonuç: Bu dönemde bakım almayı olumsuz yönde etkileyen faktörler iyi belirlenmeli ve nedenlerin çözümlerine odaklanarak perinatal bakıma erişim sağlanmalıdır. Böylece perinatal dönemdeki anne ve bebeklerin mortalite ve morbidite oranlarının düşeceği tahmin edilmektedir.
