Abstract
OBJECTIVE In singleton pregnancies, the use of cell-free DNA (cfDNA) analysis as a screening test for common fetal trisomies has spread worldwide though we still lack sufficient data for its use in triplet pregnancies. The objective of this study is to assess the performance of cfDNA testing in detecting fetal aneuploidies in triplet pregnancies as a first-tier test. METHOD We performed a retrospective cohort study including data from pregnant women with a triplet pregnancy who underwent cfDNA testing between May 1, 2017, and January 15, 2020. cfDNA was obtained by massive parallel sequencing (VeriSeq NIPT solution; Illumina®). The objectives of the study were to assess the diagnostic performance of cfDNA testing for trisomy 21 (T21) (primary outcome), trisomy 18 (T18) and 13 (secondary outcomes). RESULTS During the study period, cfDNA testing was performed in 255 women with triplet pregnancy, of which 165 (64.7%) had a neonatal outcome available. Three tests were positive for T21, one of which was confirmed by an antenatal karyotype, and the other was confirmed at birth. The third case did not undergo an invasive procedure and was not confirmed at birth (false positive). In one case, cfDNA testing was positive for T18 and was confirmed by an antenatal karyotype. There were no cases of trisomy 13 in the cohort. The no-call rate was 2.4% at first sampling. Fifty-eight (22.7%) women had embryo reduction, which in 40 (69%) of whom was performed after the cfDNA test result. CONCLUSION cfDNA testing could be offered as primary screening for main fetal aneuploidies in triplet pregnancies after provision of appropriate patient information.

Abstract
INTRODUCTION Chorioamnionitis is the inflammation of the placenta and is histologically defined as the presence of neutrophilic infiltration into the chorio-amnion membrane with and without involvement of the umbilical cord. Currently, the inflammatory mediators involved in the eliciting of inflammatory response is still largely under investigation. CD47 and CD36 are pro-inflammatory molecules that are still under investigation. The aim of this study was to determine the expressions of CD47 and CD36 in the placenta of mothers with chorioamnionitis. MATERIALS AND METHODS This was a cross-sectional study, involving a total of 100 cases that comprised of acute subchorionitis (stage I, n=20), acute chorioamnionitis (stage II, n=20), acute necrotising chorioamnionitis (stage III, n=20) and non-chorioamnionitis placenta as control (n=40). All tissue blocks were retrieved from the archived pathology record over a period of 4 years. CD36 and CD47 immunohistochemistry were performed on all cases and their expression in various cell types on the placenta were analysed. RESULTS CD36 was expressed only on the foetal vascular endothelial cells. Interestingly, CD47 showed positive staining on the neutrophils and its expression was significantly different between maternal inflammatory response stage II chorioamnionitis (n=13/20, p<0.001) with stage I and stage III chorioamnionitis. DISCUSSION Our study showed CD47 was expressed in the neutrophils and it was associated with poorer perinatal outcomes and it may have a role in the pathogenesis of chorioamnionitis.

Abstract
AIM The aims of the study were to isolate and characterize the nematode trapping fungus, Arthrobotrys oligospora, to investigate the suppressive and predacious activities of the fungus against Meloidogyne incognita and to study the potentiality of A. oligospora in controlling root-knot caused by M. incognita on tomato plants. METHODS AND RESULTS Arthrobotrys oligospora (MRDS 300) was isolated from sandy soil samples collected from Al-Beheira, Egypt. In vitro experiments revealed a high efficiency of the fungus in capturing and suppressing M. incognita second juveniles (J2 ). Microscopic observations showed that the fungus develops adhesive traps consisting of loops of hyphae. Moreover, an in vitro experiment showed that the culture filtrate of A. oligospora had a high toxic effect on the nematode. Pot experiments carried out in two seasons (2018-2019) showed that A. oligospora significantly suppressed root knot on tomato plants caused by M. incognita. The number of females, galls and nematodes in different developing stages were reduced significantly. The treatment with A. oligospora had a prominent effect on enhancing plant growth. CONCLUSION Arthrobotrys oligospora had significant suppressive and predacious effects against root-knot nematode, M. incognita. The fungus developed different forms of trapping devices in addition to secreting toxic metabolites to M. incognita. The fungus had a plant-growth promoting effect. SIGNIFICANCE AND IMPACT OF THE STUDY Arthrobotrys oligospora (MRDS 300) is a potential biological control agent that can be utilized in controlling the root-knot diseases caused by M. incognita.

Abstract
BACKGROUND To fight the COVID-19 pandemic, lockdown has been decreed in many countries worldwide. The impact of pregnancy as a severity risk factor is still debated, but strict lockdown measures have been recommended for pregnant women. OBJECTIVES To evaluate the impact of the COVID-19 pandemic and lockdown on the seroprevalence and circulation of SARS-CoV-2 in a maternity ward in an area that has been significantly affected by the virus. STUDY DESIGN Prospective study at the Antoine Béclère Hospital maternity ward (Paris area, France) from May 4 (one week before the end of lockdown) to May 31, 2020 (three weeks after the end of lockdown). All patients admitted to the delivery room during this period were offered a SARS-CoV-2 serology test as well concomitant SARS-CoV-2 RT-PCR on one nasopharyngeal sample. RESULTS A total of 249 women were included. Seroprevalence of SARS-CoV-2 was 8%. The RT-PCR positive rate was 0.5%. 47.4% of the SARS-CoV-2-IgG-positive pregnant women never experienced any symptoms. A history of symptoms during the epidemic, such as fever (15.8%), myalgia (36.8%) and anosmia (31.6%), was suggestive of previous infection. CONCLUSIONS Three weeks after the end of French lockdown, SARS-CoV-2 infections were scarce in our region. A very high proportion of SARS-CoV-2-IgG-negative pregnant women, which is comparable to that of the general population, must be taken into consideration in the event of a resurgence of the pandemic. The traces of a past active circulation of the virus in this fragile population during the spring wave should encourage public health authorities to take specific measures for this independent at-risk group, in order to reduce viral circulation in pregnant patients.

Abstract
OBJECTIVE To determine the prevalence of adult attention deficit hyperactivity disorder (ADHD) and comorbid mental disorders in a Malaysian forensic mental hospital. METHODS All adult patients admitted to the forensic wards who were able to understand Malay or English language and give written informed consent were included. Participants were assessed using the Conners Adult Attention-Deficit Diagnostic Interview for DSM-IV (for presence of adult ADHD and a history of childhood ADHD) and the Mini International Neuropsychiatric Interview (for psychiatric comorbidities). Sociodemographic and offence-related data were also collected. RESULTS Of 199 patients admitted, 120 were included for analysis. The mean age of participants was 36.3 years. 94.2% were men. 81.7% were single, divorced, or separated. 25% had a history of childhood ADHD. The prevalence of adult ADHD was 15.8%. The persistence rate was 63%. Among the 19 participants with adult ADHD, the most common psychiatric comorbidities were substance dependence (68.4%), lifetime depression (63.2%), and generalised anxiety disorder (47.4%). Compared with participants without ADHD, participants with adult ADHD were less likely to be married (0% vs 21.8%, p = 0.022) and more likely to have alcohol abuse (15.8% vs 2%, p = 0.028), lifetime manic/hypomanic episodes (42.1% vs 7.9%, p = 0.001), and generalised anxiety disorder (47.4% vs 19.8%, p = 0.017), and were of younger age at first offence (21.8 years vs 26.9 years, p = 0.021). CONCLUSIONS Adult ADHD is common in a Malaysian forensic mental hospital and is associated with unmarried status, alcohol abuse, lifetime manic/hypomanic episodes, generalised anxiety disorder, and younger age at first offence.

Abstract
The renal replacement therapy in Saudi Arabia has 3 main modalities: hemodialysis, peritoneal dialysis, and renal transplantation. Hemodialysis is one of the fastest growing industries of health care providers in Saudi Arabia. OBJECTIVE We aimed to review the health indicators of renal replacement therapy. MATERIALS AND METHODS We used the Saudi Center for Organ Transplantation Annual Report 2016. RESULTS Patients with end-stage renal disease on hemodialysis and peritoneal dialysis totaled 17,687. Saudi Arabia increased the numbers of dialysis centers and also added 2 more sectors. The Ministry of Health hospitals have 55% of the centers, government non-Ministry of Health has 9%, private and charitable hospitals have 21%, the King Abdullah Hemodialysis Project has 2%, and the outsourcing dialysis programs have 13%. There are 243 dialysis units in Saudi Arabia. Most dialysis centers are in the central region (30%); 27% are in the western region, 19% are in the southern region, 13% are in the eastern region, and 11% are in the northern region. The average net increase of dialysis patients is 6.2% annually and is projected to reach 22,000 by 2020. Causes of renal failure are mainly diabetic nephropathy (40%) and hypertensive nephropathy (38%). Hepatitis C virus positivity is at 12% and hepatitis B surface antigen positivity is at 4%. From the year 2000 renal transplantation from deceased and living donation has tripled in number, with a total of 798 kidneys transplanted. CONCLUSION Renal replacement therapy is increasing and dialysis center numbers are expected to increase. Renal transplantation numbers have improved both from living and deceased donors but further actions toward the promotion of the organ donation in Saudi Arabia is essential.

Abstract
The objective of this study was to investigate the anticoccidial effect of apple cider vinegar added to drinking water with the anticoccidial effect of amprolium to feed broiler chicken. The study has adopted an observational approach to evaluate the anticoccidial effect of apple cider vinegar on broiler chicken. The antioxidative changes were measured adding natural apple cider vinegar to drinking water. Four hundred and fifty broiler chickens were purchased from the local market and distributed into three groups (T+vc: positive control, T-vc: negative control Tv: apple cider vinegar) with 150 chickens in each group. The three groups were further replicated into 3 blocks each containing 50 chickens. The groups were fed balanced diet, amprolium was added to the feed of positive control group, and apple cider vinegar was added to the water of Tv group. Measurements of the different variables were started from week 3, at the end of each week 3 birds were chosen randomly, blood samples were collected via the wing vein, and fecal oocysts were counted from intestinal contents of each individual bird using the McMaster technique. Broiler in the control groups T+ve and T-ve showed clinical signs of coccidiosis (blood in feces) and the number of coccidial oocytes in feces increased with time. In the vinegar group, no clinical signs of coccidiosis were observed. Concentrations of total antioxidants and catalase enzyme activity significantly increased (p≤0.05); while malondialdehyde concentration significantly decreased (p≤0.05).

Abstract
The authors report a patient admitted at 12 weeks of pregnancy with an acute infectious syndrome, leading to abortion, sepsis, and multiple organ failure. Admission to intensive care unit (ICU) was needed after curettage for incomplete abortion complicated by uterine atony, hemorrhage, and septic shock. The patient had multiple organ failure and required non-invasive ventilation. Hemoculture showed streptococcus G bacteremia. She had no evidence of concurrent infection, mainly genital or urinary, except amygdalitis few days before. Hematogenous spread to the gestational sac could have possibly been the cause of her sepsis. Streptococcus G infection during pregnancy can lead to severe consequences.

Abstract
[Purpose] This study was performed to investigate the effect of the length of backpack shoulder straps on upper trapezius muscle pain threshold and craniovertebral angle. [Subjects and Methods] There were 25 participants, with ages from 15 to 23 years old. Upper trapezius pain threshold and craniovertebral angle were measured for all subjects without the backpack then re-measured after walking on a treadmill for 15 min under 2 conditions: 1) wearing a backpack with short straps; and 2) wearing a backpack with long straps. [Results] there was a significant reduction in upper trapezius pain threshold and craniovertebral angle while carrying a backpack with long shoulder straps, compared to use of a backpack with short shoulder straps or no backpack. [Conclusion] A backpack with short straps is less harmful than a backpack with long straps. This result should be considered in ergonomic design of backpacks to reduce the incidence of various physiological and biomechanical disorders.

Abstract
e17021 Background: As of the good data for radiotherapy with cetuximab and the promising results of an induction chemotherapy containing docetaxel we developed a combination of these regimes. This retrospective analysis evaluates the safety and feasibility of a TPF induction therapy under pegfilgrastim protection with a subsequent concomitant RT immunochemotherapy using cetuximab. Methods: 64 patients (8 female/56 male) with advanced (mostly metastatic; T3/T4) head & neck cancer were treated. Patients were between 39 and 78 years old (median 61), ECOG between 1 and 3. Induction therapy consisted of three 21-day-cycles TPF (75 mg/m2 docetaxel d1; 35 mg/m2 cisplatin d1,2; 750 mg/m2 5-FU d1–5) and on d7 a protective dose of 6 mg pegfilgrastim. Before and after induction therapy PET-CT was used to evaluate response. PET-CT allowed best possible RT-planning with best adapted field margins. Subsequent radioimmunochemotherapy consisted of 400 mg/m2 cetuximab on day 1 (initial dose) and seven weekly cycles of 250 mg/m2 cetuximab and 40 mg/abs cisplatin on day 1. Radiotherapy on d1–5/; 1,8 Gy/day for a median dose 61,2 Gy (59,4 - 70,2 Gy). During the whole treatment CRP was monitored twice weekly and if necessary antibiotics were administered iv. Results: All 64 patients were evaluated after therapy completion. One death occured which was not treatment related (myocard infarct). Five patients decided not to complete the treatment. The response rates were: CR 56% (36), PR 31% (20), SD 11% (7), and PD 2% (1). 10 grade 3/4 toxicities had to be observed during radioimmunotherapy (skin rash, diarrhoe). All toxicities were reversible. In five patients therapy had to be interrupted for two weeks (skin rash). Karnofsky index could be kept stable and in some cases even improved. Conclusions: The new regimen is safe, shows great promise and deserves further development. PET-CT as a diagnostic tool, pegfilgrastim as a myeloprotective agent and docetaxel/cetuximab make a good combination. Especially during the induction therapy QoL is drastically improved. No significant financial relationships to disclose.

Abstract
Basal stem rot of oil palm caused by Ganoderma boninense is of major economic importance. Observations of the low incidence of disease due to Ganoderma species in natural stands, suggest that the disease is kept under control by some biological means. Trichoderma spp. are saprophytic fungi with high antagonistic activities against soil-borne pathogens. However, their abundance and distribution are soil and crop specific. Trichoderma species have been found to be concentrated in the A1 (0-30 cm) and Be soil horizons (30-60 cm), although the abundance of Trichoderma was not significantly different between the oil palm and non-oil palm ecosystems. Characterisation of Trichoderma isolates based on cultural, morphological and DNA polymorphism showed that T. harzianum, T. virens, T. koningii and T. longibrachiatum made up 72, 14, 10 and 4% of the total Trichoderma isolates isolated. As Trichoderma species are present in the oil palm ecosystem, but at lower numbers and in locations different from those desired, soil augmentation with antagonistic Trichoderma spp. can be developed as a strategy towards integrated management of basal stem rot of oil palm.

Abstract
To help future planning of the dialysis services in the different geographical regions and health sectors in Saudi Arabia, we surveyed its 130 active hemodialysis (HD) centers using a questionnaire about their manpower, hemodialysis equipment, as well as, peritoneal dialysis and transplant patients at the end of the year 2000. Almost all the dialysis centers were on hospital campus but of variable sizes with an average ratio of 14.8 dialysis machines per center (range 2-113 machines per center). The distribution of the dialysis centers according to the geographical regions of Saudi Arabia included 18(14%) in the northern, 25(19%) in the southern, 13(10%) in the eastern, 35(27%) in the western and 39(30%) in the central region. There was a total of 6,694 dialysis patients served on 1,918 hemodialysis machines. There were 1,793(93%) HD machines capable of performing bicarbonate dialysis. There was an average ratio of 3.5 patients per one HD machine. In addition to the hemodialysis, there were 28(22%) centers engaged in peritoneal dialysis (PD) and 56(43%) centers in the follow-up of post transplant patients. The total number of the nephrologists, regardless of their expertise was 212 of whom 180(84%) spoke Arabic; the average ratio was 32 patients per nephrologist (range of 14-58). There were 1320 hemodialysis nurses of whom only 465(35%) spoke Arabic. The average ratio of patients to nurses was five patients per nurse (range of 4-6). There were 72(55%) social workers and 70(54%)dietitians with average patients ratios to these supporting services of 1:93 patients (range of 1:58-137) and 1:96 patients (range of 1:53-137), respectively. The study HD patients had a mean age of 47.8 +/- 17.1 years (range: 2-92 years); of them, 52.5% were males and 12% had non-Saudi nationality. Of the hemodialysis patients, 1,815(27%) were diabetics. The calculated net increase of dialysis population was 988 patients per year (14.8%). There were 5,700(85%) patients on regular bicarbonate dialysate. Chronic viral infection were noted in more than half of all the dialysis population: thus 3,380(50%) were positive for hepatitis C viral (HCV) serology, 448(7%) had positive hepatitis B (HBV) antigenemia and six(0.1%) had the human acquired immunodeficiency syndrome. In conclusion, our findings demonstrated a satisfactory advancement achieved in many Saudi dialysis centers in terms of equipment, personnel and patients' care. However, there should be more emphasis in the future on quality care through better self-assessment of the performance of these centers.

Abstract
Insertion sites for cysteines with optimal stereochemistry for the formation of unstrained disulfide bridges were identified in recombinant human interferon-gamma (rhu-IFN-gamma) by computer modelling. We have engineered two different disulfide cross-linked mutants, containing a pair of symmetry-related disulfide bonds, which stabilize the N-termini of both monomers of the homodimeric protein. Mutations E7C and S69C allow the formation of an intramonomer disulfide bond between helices A and D. In contrast, the A17C and H111C mutations lead to a covalent cross-link between both monomers. The AB-loop is linked to helix F. The fluorescence properties of native and disulfide cross-linked proteins were studied as a function of guanidine hydrochloride concentration. Melting temperatures (Tm) were calculated from the decrease in CD ellipticity at 220 nm. The induction of the antiviral effect was measured using A549 fibroblast cells infected with encephalomyocarditis virus. The ability to induce the expression of the HLA-DR antigen in Colo 205 cells was determined by fluorescence-activated cell scanning analysis. The stability of both mutants was strongly enhanced against temperature- and cosolvent-induced unfolding. The delta Tm of mutant IFN-gamma E7C/S69C was 15 degrees C. All measured biological activities of this mutant were equal to wild type. In the case of the other mutant IFN-gamma A17C/H111C, the delta Tm value was 25 degrees C. This mutation abolishes nearly the entire biological activity (< 1%) with no detectable changes of secondary structure in the CD spectrum. Our results illustrate the importance of the N-terminal helix A and the AB-loop for the unfolding pathway and thermodynamic stability of rhu-IFN-gamma.

Abstract
We present a general search algorithm for possible insertion sites of disulfide bonds in proteins based on the coordinates of the solved X-ray or NMR structure, allowing the insertion of disulfide bonds with a minimum of conformational tension and backbone rearrangements. The FORTRAN 77 program "Ssuitable' was written for this purpose. This methodological approach was applied to recombinant human interferon-gamma (rhu-IFN-gamma), a cytokine of great pharmaceutical interest with a wide variety of biological activities including antiviral, antiproliferative and immunomodulatory effects. A model based on the C alpha-coordinates obtained from the Brookhaven data base was built. Four different insertion sites were selected in the model, connecting the two subunits of the homodimer. The thermodynamic stability of rhu-IFN-gamma is low, limiting its clinical application. We expect that the insertion of additional new disulfide bonds will enhance the thermodynamic stability as well as protect the protein against proteolytic degradation.
