Sexual abuse and post-traumatic stress disorder in childhood, adolescence and young adulthood: a systematic review and meta-analysis.

Child sexual abuse (CSA) has been associated with mental health disorders throughout life during childhood, adolescence and adulthood; one of the most prevalent mental health conditions after CSA is post-traumatic stress disorder (PTSD). The present systematic review and meta-analysis aims to examine the association between CSA and PTSD in children and adolescents, evaluating also the role of potential effect modifiers, such as gender and geographic region. Participants were sexually abused (vs. CSA-free) children, adolescents and young adults, up to 21 years of age, with or without a PTSD diagnosis. Settings of eligible studies spanned school, college, university, community, hospital and non-hospital mental health facilities. Eligible studies were sought in PUBMED, ΕΜΒΑSE, PSYCINFO and GOOGLE SCHOLAR databases; end-of-search was set at August 31, 2020. Random-effects (DerSimonian-Laird) models were used for the pooling of studies. Results were reported as pooled odds ratios (OR) and 95% confidence intervals (95% CIs). Twenty-eight studies were identified, including a total cohort of 28,693 subjects. CSA was strongly associated with PTSD, at a similar extent in boys (pooled OR = 2.86, 95% CI 2.09-3.91) and girls (pooled OR = 2.38, 95% CI 1.76-3.23); meta-regression with gender confirmed the non-significant effect of gender. The association was present in all examined geographic regions. CSA is strongly associated with PTSD in childhood, adolescence and young adulthood, irrespectively of gender. Future studies should opt for thorough assessment of confounders and examine regions with paucity of studies, such as East Asia and Latin America.

A comparative autopsy study of the injury distribution and severity between suicidal and accidental high falls.

Falls are the second cause of accidental deaths worldwide. Falls from height are also a common method of suicide. The aim of this study is to compare the characteristics of the victims, the circumstances of the fall and the severity and distribution of the injuries reported in an autopsy case series of falls from height. This study is a retrospective analysis of consecutive autopsy cases of suicidal and accidental falls from height which were investigated in the Department of Forensic Medicine and Toxicology of the National and Kapodistrian University of Athens during the period 2011-2019. The recorded variables included demographic data of the victim, height of fall, length of hospital stay, toxicological results, the existence and location of injuries and Injury Severity Score (ISS). Victims of suicidal falls were younger (55.53 vs. 62.98, p = 0.001), they fell from higher heights (12.35 vs. 5.18 m, p < 0.001), and they sustained more severe injuries compared with victims of accidental falls (ISS 51.01 vs. 40.88, p < 0.001). Injuries in the thorax, abdomen, pelvis, upper and lower extremities were more frequently observed after a suicidal fall (93.6% vs. 67.3%, 72.1% vs. 21.4%, 72.1% vs. 27.6%, 42.9% vs. 15.3%, 45.7% vs. 13.3%, respectively-p < 0.001), probably due to the higher height of fall. Our study outlines the differences in the profile of the victims and in the severity of injuries caused by falls from height depending on the intention of the victim to fall. However, a distinctive injury pattern in victims of suicidal falls was not demonstrated.

Intimate partner violence in Greece: a study of 664 consecutive forensic clinical examinations.

BACKGROUND: Intimate partner violence (IPV) is a well-known phenomenon, which affects mostly women. While IPV victims may attend emergency departments (EDs) seeking medical care, not all of them will make an allegation against their abusers. OBJECTIVE: The aim of this study was to examine the prevalence and the characteristics of the victims, who had made an allegation about the violent incident and had been examined by a forensic pathologist for judicial purposes, and had attended EDs seeking medical care, before the forensic examination. METHODS: We reviewed the archives of clinical examinations that were conducted at the Department of Forensic Medicine and Toxicology of National and Kapodistrian University of Athens during a 5-year period (2012-16). RESULTS: Six hundred sixty-four clinical examinations were conducted at our Department for IPV allegations. According to our findings, women were more likely to seek medical care than men. Victims who have attended EDs were more likely to have sustained injuries located at least on the head or on the lower limbs. CONCLUSION: The majority of IPV victims in the broader region of Attica (Greece) were women, usually married, and aged between 30 and 49 years old. Despite the fact that the majority of IPV incidents are not reported to police, every person who is engaged in the process of dealing with IPV victims has to be educated and adequately informed about this phenomenon, its implications and the possible ways to deal with it. Furthermore, victims need to be educated and informed adequately in waiting rooms of EDs.

Recent aspects of the effects of zinc on human health.

Zinc (Zn) is one of the most important essential nutrients of great public health significance. It is involved in numerous biological functions and it is considered as a multipurpose trace element, due to its capacity to bind to more than 300 enzymes and more than 2000 transcriptional factors. Its role in biochemical pathways and cellular functions, such as the response to oxidative stress, homeostasis, immune responses, DNA replication, DNA damage repair, cell cycle progression, apoptosis and aging is significant. Zn is required for the synthesis of protein and collagen, thus contributing to wound healing and a healthy skin. Metallothioneins are metal-binding proteins and they are potent scavengers of heavy metals, including Zn, and protect the organism against stress. Zn deficiency is observed almost in 17% of the global population and affects many organ systems, leading to dysfunction of both humoral and cell-mediated immunity, thus increasing the susceptibility to infection. This review gives a thorough insight into the most recent evidence on the association between Zn biochemistry and human pathologies, epigenetic processes, gut microbial composition, drug targets and nanomedicine.

Sudden unexplained death in the young: epidemiology, aetiology and value of the clinically guided genetic screening.

Aims: To determine the incidence and the causes of sudden death (SD) in persons aged 1-35 years old and the diagnostic yield of clinically guided genetic screening in the sudden arrhythmic death syndrome (SADS) victims' families. Methods and results: Incidence and causes of SD in the Attica region of Greece in 2002-10 were determined using death certificates and autopsy reports. We evaluated clinically consecutive families of SADS victims and if a clinical diagnosis was established, we proceeded to targeted genetic analysis. Out of 6030 deaths, 56% were due to traumatic or violent causes, 40.5% were natural deaths, and 3.3% were of undetermined cause. There were 349 SD cases. Cardiovascular causes accounted for 65%, non-cardiovascular causes for 17%, and SADS for 18%. Clinical evaluation identified an inherited heart disease in 5/20 SADS families (25%). Targeted genetic analysis identified a causative mutation in all of the five screened families and reconfirmed the diagnosis in three of five proband victims. Clinical and genetic evaluation of 28 family members identified eight affected carriers and eight non-affected carriers. Molecular autopsy failed to identify any of these families. Conclusion: Sudden death in the young is of cardiovascular origin in the majority of cases. A considerable rate of SD cases remains of unknown cause on post-mortem. Apart from channelopathies, subclinical forms of inherited structural heart diseases would appear to be implicated in SADS. Clinically guided genetic screening has a significant diagnostic yield and identifies affected families that would have been missed by the current suggested molecular autopsy panel.

A fully validated method for the simultaneous determination of 11 antihistamines in breast milk by gas chromatography-mass spectrometry.

Antihistamines are excreted into breast milk in small amounts; however, there are no adequate published studies or data concerning their effects on newborns and safety during breastfeeding. Thus, the development of sensitive and specific methodologies for the determination of antihistamines in breast milk is critical. A simple and sensitive GC-MS method for the simultaneous determination of 11 antihistamines (diphenhydramine, orphenadrine, chlorpheniramine, dimethindene, meclozine, hydroxyzine, loratadine, desloratadine, cetirizine, rupatadine and ebastine) in breast milk was developed and validated. The antihistamines were solid-phase extracted and derivatized with acetic anhydride and n-propanol. Diazepam-d5 , hydroxyzine-d4 and cetirizine-d8 were used as internal standards. Absolute recovery values for all analytes ranged from 70.5 to 120.0%, while the limits of detection and quantification for all analytes were 1.50 and 5.00 ng/mL, respectively. All calibration curves were linear (R2 ≥ 0.990) within the range 5.00-1000.0 ng/mL. Accuracy (Er ) ranged between -7.6 and 7.0%, while precision (RSD) was <12% for all antihistamines. The developed method is suitable for the investigation of antihistamine-related clinical cases, as well as for pharmacokinetic and breastfeeding safety studies.

Bioanalysis of antihistamines for clinical or forensic purposes.

Antihistamines are a class of drugs that inhibit the action of histamine and are used to alleviate symptoms associated with allergic reactions, but some of them can cause side effects, the most unpleasant and dangerous of which are the sedative effects that may hinder important psychological functions and impair skilled performance. These side effects could decrease safety in certain common and critical tasks, such as driving or operating machinery, leading to accidents. Antihistamines can also cause intoxications, sometimes lethal, especially when co-administered with alcohol or other sedative drugs. Thus, the development of analytical methods for their determination in biological fluids is considered to be useful for the investigation of clinical and forensic cases. These methodologies could also be used for pharmacokinetic studies. Several liquid and a few gas chromatographic methods have been developed for the determination of antihistamines in biological matrices after proper pretreatment procedures. This article reviews the published analytical methodologies that were gathered through the search in PubMed database and the recent developments on isolation or determination of antihistamines in biological materials. Current trends and future perspectives on bioanalysis of antihistamines are also discussed. Copyright © 2016 John Wiley & Sons, Ltd.

The Role of Dialysis Membranes on Intradialytic Selenium Removal and on Selenium Status in Patients Receiving Renal Replacement Therapy.

BACKGROUND/AIMS: Dialysis membrane has been implicated in selenium (Se) deficiency in hemodialysis (HD). Intradialytic Se removal into dialysate through different membranes was investigated. METHODS: We studied 19 patients on standard HD with low-flux polysulfone membrane (group A), 10 patients on standard HD with ethylene vinyl alcohol membrane (group B), 12 patients on hemodiafiltration (HDF; group C) and 16 healthy subjects (control group D). Se was measured in blood before and after dialysis session and in effluent dialysate every hour during session. RESULTS: In all patients together, pre-dialysis serum Se levels were lower than those in control group, but, in a separate analysis, only in standard HD. In all patient groups, there was a net Se removal into dialysate but it was greater in HDF patients who, however, had similar pre-dialysis serum Se levels to those in healthy controls. CONCLUSION: An intradialytic Se loss was found with all 3 membrane types, but it is not the principal factor for Se depletion in HD.

Redefining Vascular Anatomy of Posterior Tibial Artery Perforators: A Cadaveric Study and Review of the Literature.

INTRODUCTION: Perforator flaps whether in a free or pedicled form are essential in leg reconstruction, requiring meticulous dissection based on a detailed understanding of vascular topographic anatomy. Numerous investigators have addressed this issue. However, the directionality of their fascial exit has not been greatly discussed in the literature. Subfascial course of the perforating vessel is a crucial determinant for optimal perforator selection especially when the propeller perforator flap option is considered, because an angulated fascial penetration would eventually result in perforator kinking which would additionally compromise vascular patency. The aim of the current study was to investigate the vascular anatomy of posterior tibial artery evaluating a wide range of parameters, including perforators' subfascial directionality, to precisely determine constant reliable perforator sites, in relation to surface landmarks on the medial aspect of the lower leg. MATERIAL AND METHODS: Dissections in 30 lower legs from 25 fresh cadavers were performed. The lower leg was divided into 3 equal vascular zones. Measurements were taken in reference to anatomical landmarks. Perforator clusters to 5-cm intervals from medial malleolus were recorded and analyzed. Vessels with external diameter less than 0.5 mm were excluded. Data regarding the number, distribution, type, external diameter, length from posterior tibial artery, distance, and subfascial directionality were collected and treated. RESULTS: A total of 155 perforators were identified (average number, 5 per leg; average diameter, 1.0 mm). Septocutaneous (127/155) perforators predominated, followed by musculocutaneous (19/155) and septomusculocutaneous (9/155). Most was concentrated in the middle (73/155) and distal (64/155) tertile. There were no septomusculocutaneous perforators at the distal third of the leg, whereas septocutaneous perforators were encountered into all vascular tertiles. An average of 2 comitant veins accompanied each perforator. Length and diameter related to the perforators' location. There was a significant association between perforator length and type. Cluster analysis revealed that reliable perforators were identified within the 21 to 25, 26 to 30, and 16 to 20 cm intervals. CONCLUSIONS: Clinically optimal perforators for the first time were precisely located in relation to subfascial directionality, vascular diameter, and length from the source artery. Continuous improving details of vascular anatomy will further evolve perforator flaps' applications.

A fully validated method for the determination of lacosamide in human plasma using gas chromatography with mass spectrometry: application for therapeutic drug monitoring.

A simple gas chromatographic method with mass spectrometry detection was developed and validated for the determination of lacosamide in human plasma. Lacosamide and the internal standard, levetiracetam-d6, were extracted from 200 µL plasma, by a solid-phase extraction through HF Bond Elut C18 columns, and derivatized using N-methyl-N-tert-butyldimethylsilyltrifluoroacetamide with 1% tert-butyldimethylsilylchloride in acetonitrile. The limit of quantification was found to be 0.20 µg/mL and the assay was linear up to 20.0 µg/mL with correlation coefficient ≥0.994. The intra- and interday precision values were <4.1% in terms of relative standard deviation (%) and the values of intra- and interday accuracy were found to be within -7.2 and 5.3% in terms of relative error (%). Absolute recovery of the method for lacosamide was determined at three concentration levels and ranged from 92.5 to 97.6%. The developed method uses small volumes of plasma and proved to be simple, rapid, and sensitive for the determination of lacosamide in plasma. This method can be used in routine every day analysis of plasma samples obtained from patients who follow respective antiepileptic treatment and for the investigation of clinical and forensic cases where lacosamide is involved.

2C-I-NBOMe, an "N-bomb" that kills with "Smiles". Toxicological and legislative aspects.

Substituted phenethylamines are a class of designer drugs that have recently emerged in the drug abuse market. Such substances remain legal to use, possess, and supply until these compounds become classified as scheduled. 2C-I-NBOMe or 25I-NBOMe is the N-benzyl-derivative of the iodo-substituted dimethoxy-phenethylamine (2C-I) that appeared recently in the drug market under the street name "N-Bomb". Due to its high potency, intoxications and fatal cases related to 2C-I-NBOMe use are increased worldwide. The use and trafficking of this substituted phenethylamine is banned only in some countries. A comprehensive review was performed using PubMed and Medline databases, together with additional non-peer reviewed information sources, including books and publications of state authorities in different countries, regarding chemistry, availability, pharmacology, and toxicology of 2C-I-NBOMe. Intoxications or lethal cases, published or reported, as well as the current legislation on this newly introduced drug are also reviewed.

Development and validation of a LC/MS method for the determination of Δ(9)-tetrahydrocannabinol and 11-carboxy-Δ(9)-tetrahydrocannabinol in the larvae of the blowfly Lucilia sericata: Forensic applications.

In a number of forensic toxicological cases, Δ(9)-tetrahydrocannabinol (THC) and its metabolite 11-carboxy-delta-9-tetrahydrocannabinol (THCA) are frequently considered as contributor factors to the event. To that, a liquid chromatographic mass spectrometric method is described for the identification and quantitation of THC and its metabolite THCA in the forensically important larvae of L. sericata. Larvae of Lucilia sericata were fortified with varying concentrations of THC and THCA covering the calibration range between 10 and 500pg/mg. For the isolation of the analytes from larvae, several extraction techniques were evaluated and finally liquid-liquid extraction under acidic pH was selected using hexane-ethyl acetate (50:50, v/v) as extraction solvent. For the chromatographic separation, a Waters Symmetry® C18 analytical column was used while the mobile phase was acetonitrile-ammonium acetate (2mM) (30:70, v/v). The detection was performed using electrospray ionization source in negative mode (ESI-) and the selected ions monitored were m/z 313 for THC and m/z 343 for THCA. The proposed method which is simple and sufficiently sensitive for the detection of THC and THCA even in a single larva sampling, assisted the investigation of a forensic case.

The microvascular anatomy of superior and inferior gluteal artery perforator (SGAP and IGAP) flaps: a fresh cadaveric study and clinical implications.

BACKGROUND: Our study aimed to highlight anatomical similarities, differences, and variations in the microvascular anatomy between superior and inferior gluteal artery perforator (SGAP and IGAP) flaps. METHOD: Thirty gluteal flaps (15 SGAP and 15 IGAP) were studied on 22 adult fresh cadavers. We recorded the number and location of perforators, the characteristics of the main perforator (course, length, and diameter at the level of division at the greater sciatic foramen), and the anatomical variations of the submuscular venous plexus. RESULTS: The mean number of perforators was similar in both flaps (n = 7). We found a statistically significant difference in the total length of the vascular pedicle between SGAP (mean = 9.80 cm) and IGAP (mean = 13.36 cm) flaps, which correlated strongly with the difference in the intramuscular length (mean difference = 3.40 cm) of the perforator. There was no statistically significant difference in the diameter of the superior and inferior gluteal vessels at the point of pedicle division. The complex submuscular venous plexus, which is typically found on SGAP flaps deep to the sacral fascia, was never encountered on IGAP flaps. Perforators originating from the inferior gluteal artery were found on the lower half of five superior gluteal flaps. These were dominant perforators in two cases. We also report a rare anatomical communication between superior and inferior gluteal vessels deep to the piriformis muscle and a case of atheromatous disease of the inferior gluteal artery. CONCLUSION: Our findings are highly relevant to clinical practice and contribute to the understanding of the vascular anatomy of SGAP and IGAP flaps and the successful use of these challenging flaps.

Vitreous humor in the forensic toxicology of quetiapine and its metabolites.

PURPOSE: Τhe aim of the present study was to investigate the use of vitreous humor as an alternative biological material in forensic toxicology for the determination of quetiapine, 7-hydroxy-quetiapine, and nor-quetiapine. The distribution of these substances in vitreous humor was studied by determining and correlating their concentrations in vitreous humor with the respective concentrations in blood. METHODS: During this study, a method for the determination of these substances was developed, validated and applied to postmortem samples obtained from 16 relative forensic cases. The sample preparation procedure included the isolation of the analytes from vitreous humor and blood samples using solid-phase extraction, with Bond Elut LRC C18 columns followed by derivatization with BSTFA with 1% TMCS prior to GC/MS analysis. RESULTS: The developed method is characterized by a dynamic range of 10.0-1000.0 ng/mL (R2 ≥ 0.991) for the three substances, with a limit of detection and quantification of 3.0 and 10.0 ng/mL, respectively. Accuracy and precision were below 8.09% and 8.99%, respectively, for both biological materials, while absolute recovery for the three substances was greater than 81%. According to the results, quetiapine, 7-hydroxy-quetiapine, and nor-quetiapine are easily distributed in vitreous humor. CONCLUSION: The results of the study indicate the usefulness of vitreous humor in toxicological analysis for the determination of these substances, especially when the traditional biological materials are not available. The levels of quetiapine and its metabolites in vitreous humor as well as the vitreous humor to blood concentration ratios can provide important information for a more thorough toxicological investigation of forensic cases.

Determination of Δ9-tetrahydrocannabinol, 11-nor-carboxy-Δ9-tetrahydrocannabinol and cannabidiol in human plasma and urine after a commercial cannabidiol oil product intake.

PURPOSE: Cannabidiol (CBD) products are widely used for pain relief, sleep improvement, management of seizures etc. Although the concentrations of Δ9-tetrahydrocannabinol (Δ9-THC) in these products are low (≤0.3% w/w), it is important to investigate if its presence and/or that of its metabolite 11-nor-carboxy-Δ9-THC, is traceable in plasma and urine samples of individuals who take CBD oil products. METHODS: A sensitive GC/MS method for the determination of Δ9-THC, 11-nor-carboxy-Δ9-THC and CBD in plasma and urine samples was developed and validated. The sample preparation procedure included protein precipitation for plasma samples and hydrolysis for urine samples, solid-phase extraction and finally derivatization with N,O-bis(trimethylsilyl)trifluoroacetamide) with 1% trimethylchlorosilane. RESULTS: For all analytes, the LOD and LOQ were 0.06 and 0.20 ng/mL, respectively. The calibration curves were linear (R2 ≥ 0.992), and absolute recoveries were ≥91.7%. Accuracy and precision were within the accepted range. From the analysis of biologic samples of 10 human participants who were taking CBD oil, it was realized that Δ9-THC was not detected in urine, while 11-nor-carboxy-Δ9-THC (0.69-23.06 ng/mL) and CBD (0.29-96.78 ng/mL) were found in all urine samples. Regarding plasma samples, Δ9-THC (0.21-0.62 ng/mL) was detected in 10, 11-nor-carboxy-Δ9-THC (0.20-2.44 ng/mL) in 35, while CBD (0.20-1.58 ng/mL) in 25 out of 38 samples, respectively. CONCLUSION: The results showed that Δ9-THC is likely to be found in plasma although at low concentrations. In addition, the detection of 11-nor-carboxy-Δ9-THC in both urine and plasma samples raises questions and concerns for the proper interpretation of toxicological results, especially considering Greece's zero tolerance law applied in DUID and workplace cases.

Diagnostic value of cardiac troponin I in postmortem diagnosis of myocardial infarction.

Troponin I (cTnI) is a very sensitive biochemical marker for the diagnosis of myocardial infarction (MI). Cardiac troponin (cTnI or cTnT) has nearly absolute myocardial tissue specificity, thereby reflecting even microscopic zones of myocardial necrosis. The aim of this study is to evaluate the pericardial fluid levels of cTnI in medicolegal autopsy cases where patients died of MI and compare them with cases where patients died of other causes. This study included 89 cases selected during a 1-year period from medicolegal autopsies. These were classified into 4 groups: (A) myocardial infarction (n = 28), (B) salt water drowning (n = 20), (C) death resulting from injury in the respiratory system (n = 16), and (D) other causes of death (n = 25), excluding MI. The mean concentrations of cTnI were 1067.03 mg/dL for group A, 546.98 mg/dL for group B, 398.75 mg/dL for group C, and 577.47 mg/dL for group D. In cases with MI (group A), there was a significant difference in the levels of cTnI compared with the other cases. More research needs to be done in order for a cutoff level to be determined.

Toxicogenomic evaluation of chemically induced chromosomal imbalance using DNA image analysis.

The study of carcinogenic potential of a variety of chemical agents such as food additives and drugs of abuse via the application of various in vitro methodologies constitutes the first step for the evaluation of their toxicogenomic profile. Considering the chromosomal theories of carcinogenesis, where it is stated that aneuploidy and chromosomal imbalance (instability) are among the main causes of carcinogenesis, chemicals capable to induce such changes in the cells could be considered as potential carcinogens. Chromosomal imbalance and aneuploidy directly affect the overall DNA content of the exposed cell as well as other cellular morpho- and densitometric features. These features can be measured by means of computerized DNA image analysis technologies and include DNA content (DNA Index), Proliferation Index, Ploidy Balance, Degree of Aneuploidy, Skewness and Kurtosis. Considering the enormous number of untested chemicals and drugs of abuse that follow non-genotoxic mechanisms of carcinogenesis, the establishment of a reliable technology for the estimation of chemically induced chromosomal imbalance is of particular importance in toxicogenomic studies. In the present article and based on our previously published work, we highlight the advantages of the applications of DNA image analysis technology in an easy-to-use experimental model for the evaluation of the potential risk of various chemicals. The use of this technology for the detection of chemically induced chromosomal instability will contribute to the development of safer regulatory directives concerning the use of chemicals in food and pharmaceutical industry, as well as in the clarification of mechanisms of action of drugs of abuse.

Evaluation of the accuracy of different molar teeth measurements in assessing sex.

Teeth are considered to be a very useful tissue for sex determination and molars are among the most dimorphic teeth. Even though mesiodistal (MD) and buccolingual (BL) crown diameters are usually employed for sex assessment, alternative measurements like MD and BL cervical diameters as well as crown and cervical diagonal diameters have been developed. This study explores the utility of crown and cervical MD, BL and diagonal measurements of molars in sex assessment when used separately. A total of 254 permanent molars (excluded third molars) from 101 individuals (51 males, 50 females) from the Athens Collection were examined. Stepwise discriminant analysis was used to evaluate the accuracy of each diameter group in assessing sex. It was found that the accuracy ranges from 65.5 to 88.4 %. Cervical diagonal diameters are the most accurate followed by crown diagonal diameters, and crown and cervical MD and BL diameters. Therefore the high classification accuracy of diagonal diameters show that these measurements are more reliable for sex determination than the traditional MD and BL and can be considered a promising method for sex assessment from human teeth.

The influence of expanded carrier screening in assisted reproductive techniques: changed the 'game'- review.

Expanded carrier screening constitutes a new scientific tool able to detect conditions that can be treated immediately after birth or during pregnancy. Its implementation could affect both the prenatal period and assisted reproductive techniques. It is strongly beneficial as it provides much useful information to future parents concerning the medical status of their offspring. In addition, the definition of 'serious/severe', regulating preimplantation diagnosis, donor insemination, and even the definitions of prerequisites for abortion diseases, should be reformed including all clinically severe diseases. On the other hand, controversies may arise especially regarding gamete donation. Future parents and offspring maybe informed regarding donors' demographic and medical characteristics. This study aims to investigate the effects of the implementation of expanded carrier screening in the reformation of the definition of 'severe/serious' disease, the decision-making of future parents, gamete donation, and the possible new moral dilemmas that may arise.

Domestic Violence During the COVID-19 Pandemic: A Systematic Review.

BACKGROUND: COVID-19 outbreak and the followed confinement measures have raised concerns to specialists worldwide regarding the imminent increase in domestic violence cases. The present systematic review aims to identify the international trends in domestic violence during the COVID-19 epidemic and to examine the possible differences among all population groups and different geographic areas worldwide. METHOD: The following databases were accessed: DOAJ, ERIC, Google Scholar, ProQuest, Pubmed, PsycNet, and SCOPUS, up to July 22, 2020. RESULTS: A total of 32 studies were considered eligible. Data from North America, Europe, Asia-Pacific Area, Africa, and worldwide researches were retrieved. COVID-19 has caused an increase in domestic violence cases, especially during the first week of the COVID-19 lockdown in each country. In children, however, although the specialists' estimations suggested an increase in child maltreatment and abuse cases, the rate of police and social services' reports has declined during the COVID-19 pandemic. School closures that isolated students at home seemed to have contributed to this decrease. CONCLUSIONS: Domestic violence has been a considerable issue imposed by the COVID-19 epidemic to a worldwide context. The home confinement led to constant contact between perpetrators and victims, resulting in increased violence and decreased reports. In order to minimize such issues, prevention measures and supporting programs are necessary.
