Authors: Et al. Juma 
Published: December 2019

The proposal of nonlinear models is one of the most important methods in time series analysis, which has a wide potential for predicting various phenomena, including physical, engineering and economic, by studying the characteristics of random disturbances in order to arrive at accurate predictions.
In this, the autoregressive model with exogenous variable was built using a threshold as the first method, using two proposed approaches that were used to determine the best cutting point of [the predictability forward (forecasting) and the predictability in the time series (prediction), through the threshold point indicator]. B-J seasonal models are used as a second method based on the principle of the two proposed approaches in determining the best seasonal model. Then they are compared with the obtained models from two methods that mentioned above of the two approaches within a group of the criteria as AIC, MDL, Loss Function, BIC, FPE, MSE, in addition the proposed weighted comparison criteria to determine the best model for representing the wind speed data as input variable, soil and dust as an output variable, in Baghdad Station from January 1956 to December 2012.

Abstract
Background Ketamine has been reported to cause neonatal neurotoxicity in a variety of developing animal models. Various studies have been conducted to study the mechanism of neurotoxicity for general anesthetic use during the neonatal period. Previous experiments have suggested that developmentally generated granule neurons in the hippocampus dentate gyrus (DG) supported hippocampus-dependent memory. Therefore, this study aimed to investigate whether ketamine affects the functional integration of developmentally generated granule neurons in the DG. For this purpose，the postnatal day 7 (PND-7) Sprague-Dawley (SD) rats were divided into the control group and the ketamine group (rats who received 4 injections of 40 mg/kg ketamine at 1 h intervals). To label dividing cells, BrdU was administered for three consecutive days after the ketamine exposure; NeuN+/BrdU+ cells were observed by using immunofluorescence. To evaluate the developmentally generated granule neurons that support hippocampus-dependent memory, spatial reference memory was tested by using Morris Water Maze at 3 months old, after which the immunofluorescence was used to detect c-Fos expression in the NeuN+/BrdU+ cells. The expression of caspase-3 was measured by Western blot to detect the apoptosis in the hippocampal DG.ResultsThe present results showed that the neonatal ketamine exposure did not influence the survival rate of developmentally generated granule neurons at 2 and 3 months old, but ketamine interfered with the integration of these neurons into the hippocampal DG neural circuits and caused a deficit in hippocampal-dependent spatial reference memory tasks.ConclusionsIn summary, these findings may promote more studies to investigate the neurotoxicity of ketamine in the developing brain.

Abstract
Background Adolescents with acute psychiatric disorders are typically treated with long-term clinical admission. However, long term admission may be associated with a variety of negative outcomes. This pilot study presents a new model of care, that is, the combined application of intensive home treatment and the possibility of short term stay at a psychiatric high & intensive care.

Methods In total 112 referred adolescents with mixed diagnoses participated in this longitudinal observational design. Clinical outcome was measured by the Health of the Nation Outcome Scales for Children and Adolescents (HoNOSCA) which measures the severity of multiple mental health problems. The HoNOSCA was clinician-rated at intake, after two months and after four months at discharge. Change in HoNOSCA total score was analysed with paired t-tests. Outcome moderators were gender, age, primary diagnosis, clinical admission, home treatment-time, medication and additional therapies. Follow up data were completed for 62 patients after two months and for 53 after four months.

Results Participants aged between 11 and 18 years ( M = 14.8 years, SD = 0.3; 52% female). Mean HoNOSCA total score at intake was 18.8 (SD = 5.2), after two months 13.0 (SD = 5.0); after four months resulting in a score of 9.3 (SD = 5.2). None of the moderators tested showed a significant effect on HoNOSCA scores. However, a control group could not be used because of the severe psychopathology and high risk for suicidality and the lack of an effective treatment intervention for a comparable study group.

Conclusion With a symptom decrease of over 50% within four months as measured by the HoNOSCA, including less risk for hospitalization, this new model appears promising and of clinical relevance. Nevertheless, further research regarding stability of treatment outcome is warranted and evaluation of long-term effects of this model in follow-up studies is needed.

Abstract
Background Cotton grows in altering environments that are often unfavorable or stressful for its growth and development. Consequently, the plant must cope with abiotic stresses such as soil salinity, drought, and excessive temperatures. Alkali-salt stress response remains a cumbersome biological process and is regulated via a multifaceted transcriptional regulatory network in cotton Results To discover the molecular mechanisms of alkali-salt stress response in cotton, a comprehensive transcriptome analysis was carried out after alkali-salt stress treatment in three accessions of Gossypium hirsutum with contrasting phenotype. Expression level analysis proved that alkali-salt stress response presented significant stage-specific and tissue-specific. GO enrichment analysis typically suggested that signal transduction process involved in salt-alkali stress response at SS3 and SS12 stages in leaf; carbohydrate metabolic process and oxidation-reduction process involved in SS48 stages in leaf; the oxidation-reduction process involved at all three phases in the root. The Co-expression analysis suggested a potential GhSOS3/GhCBL10-SOS2 network was involved in salt-alkali stress response. Furthermore, Salt-alkali sensitivity was increased in GhSOS3 and GhCBL10 Virus-induced Gene Silencing (VIGS) plants. Conclusion The findings may facilitate to elucidate the underlying mechanisms of alkali-salt stress response and provide an available resource to scrutinize the role of candidate genes and signaling pathway governing alkali-salt stress response Keywords: Alkali-Salt Stress; RNA-Seq; Gene Co-Expression; Gossypium Hirsutum Races; WGCNA

Abstract
Background: Hearing loss (HL) represents the most common congenital sensory impairment with an incidence of 1-5 per 1000 live births. Non-syndromic hearing loss (NSHL) is an isolated finding that is not part of any other disorder accounting for 70% of all genetic hearing loss cases.
Methods: In the current study , we reported a polygenic mode of inheritance in an NSHL consanguineous family using exome sequencing technology and we evaluated the possible effect of the detected single nucleotide variants (SNVs) using in silico methods.
Results: Two bi-allelic SNVs were detected in the affected patients; a MYO15A (. p.V485A) variant, and a novel MITF (p.P338L) variant. Along with these homozygous mutations, we detected two heterozygous variants in well described hearing loss genes ( MYO7A and MYH14). The novel MITF p. Pro338Leu missense mutation was predicted to change the protein structure and function.
Conclusion: A novel MITF mutation along with a previously described MYO15A mutation segregate with an autosomal recessive non-syndromic HL case with a post-lingual onset. The findings highlight the importance of carrying whole exome sequencing for a comprehensive assessment of HL genetic heterogeneity.

Abstract
B ackground: Enteral nutrition should be implemented as early as possible in patients with moderate or severe acute pancreatitis. This study was designed to evaluate the feasibility and effectiveness of ultrasound-guided Freka-Trelumina tube placement for enteral nutrition in acute pancreatitis. Methods: Patients with severe acute pancreatitis admitted to Shengjing Hospital of China Medical University who needed Freka-Trelumina tube placement for enteral nutrition and gastrointestinal decompression were included in the current study. The relevant evaluation indicators of tube placement included the success rate of tube placement, tube placement time, tube shift rate, and blocking rate. In addition, the evaluation indicators of ultrasound-guided tube placement (from 1 January 2018 to 31 July 2019) were compared with those of previous endoscope-guided placement (from 1 January 2015 to 31 December 2017) by analysing the data from the electronic medical record system. Results: The success rate of ultrasound-guided tube placement was 90.7% (49/54). All 49 patients tolerated the Freka-Trelumina feeding tube. The average ultrasound-guided tube placement time for the 49 patients was 18.4 ± 12.8 min (range, 5-36 min). The Freka-Trelumina feeding tube had a shift rate of 10.2% (5/49). The blocking rate of the Freka-Trelumina feeding tube was 12.2% (6/49). The success rate of tube placement, tube shift rate and blocking rate for endoscope-guided tube placement were 100% (62/62), 11.3% (7/62), and 12.9% (8/62), respectively. The average endoscope-guided tube placement time for the 62 patients was 16.5 ± 5.7 min (range, 12-31 min). The comparison between the ultrasound-guided group and the endoscope-guided group showed that the success rate of tube placement, tube placement time, tube shift rate and blocking rate were similar. Conclusion: The ultrasound-guided method can be done non-invasively at the bedside, which is safe and convenient, and the Freka-Trelumina feeding tube can be placed in time to achieve the goal of early enteral nutrition and gastrointestinal decompression.

Published: December 2019

Abstract
Background Application of positive end-expiratory pressure (PEEP) improves lung aeration and reduces mechanical stress during mechanical ventilation. Although numerous approaches for PEEP titration have been proposed, there is no accepted strategy to titrate optimal PEEP. By analyzing the intratidal compliance profiles, PEEP may be titrated patient-individually. Methods After obtaining informed consent, we measured respiratory system mechanics, regional ventilation in 60 consecutive patients undergoing elective surgery, randomly allocated to the control group (PEEP = 5 cmH 2 O) or the intervention group receiving individually titrated PEEP, guided by intratidal compliance profile analysis. Primary endpoint was the frequencies of nonlinear intratidal compliance (C RS ) profiles of the respiratory system (horizontal, increasing, decreasing and mixed). We further investigated respiratory and hemodynamic variables and regional ventilation. Results Frequencies of C RS profiles were comparable between the groups. Besides PEEP [control: 5.0 (0.0), intervention: 5.8 (1.1) cmH 2 O, p<0.001] respiratory and hemodynamic variables were comparable between the two groups. The compliance profile analysis showed no significant differences between the two groups. The loss of ventral and dorsal regional ventilation was higher in the control [ventral: 41.0 (16.3) %, dorsal: 25.9 (13.8) %] than in the intervention group [ventral: 29.3 (17.6) %, dorsal: 16.4 (12.7) %, p (ventral) = 0.039, p (dorsal) = 0.028]. Conclusions Individualized PEEP titration according to bedside compliance profile analysis improves regional ventilation in terms of global aeration gain without affecting respiratory and hemodynamic variables negatively and might be a promising approach to patient-individual ventilation settings. However, differences in dorsal to ventral ventilation distribution were not found. Unfavorable compliance profiles indicating tidal derecruitment were found less often than in earlier studies.
Where have all the susceptible gonococci gone? A historical review of changes in MIC distribution over the past 75 years

Published: December 2019

Abstract
Background Does the emergence of antimicrobial resistance in Neisseria gonorrhoeae include the erasure of highly susceptible strains or does it merely involve a stretching of the MIC distribution? If it was the former this would be important to know as it would increase the probability that the loss of susceptibility is irreversible.Methods We conducted a historical analysis based on a literature review of changes of N. gonorrhoeae MIC distribution over the past 75 years for 3 antimicrobials (benzylpenicillin, ceftriaxone and azithromycin) in five countries (Denmark, Japan, South Africa, the United Kingdom and the United States).Results Changes in MIC distribution were most marked for benzylpenicillin and showed evidence of a right shifting of MIC distribution that was associated with a reduction/elimination of susceptible strains in all countries. In the case of ceftriaxone and azithromycin, where only more recent data was available, right shifting was also found in all countries but the extent of right shifting varied and the evidence for the elimination of susceptible strains was more mixed.Conclusions The finding of right shifting of MIC distribution combined with reduction/elimination of susceptible strains is concerning since it suggests that this shifting may not be reversible. Since excess antimicrobial consumption is likely to be responsible for this right shifting, this insight provides additional impetus to promote antimicrobial stewardship.

Published: December 2019

Abstract
Background: Recent studies show that oxidative stress is associated with the pathogenesis of schizophrenia. There are two major types of antioxidant systems in vivo, namely enzymatic antioxidants and non-enzymatic antioxidants. This study investigated differences of non-enzymatic antioxidant between schizophrenia patients and healthy controls.
Methods: Peripheral UA, ALB and TBIL of 107 schizophrenic patients in acute stage and 101 in remission stage were measured respectively, so were 273 healthy controls.
Results: The levels of UA (P=0.020) and TBIL (P<0.001) of schizophrenic patients in acute stage were higher than those of healthy controls, while the level of ALB (P<0.001) was lower. Similar results were detected form schizophrenic patients in remission stage. Schizophrenic patients in acute stage were divided into antipsychotics-use subgroup (n=56) and antipsychotics-naïve/free subgroup (n=51). The level of UA (P=0.001) in antipsychotics-use subgroup was higher than that in antipsychotics-naïve/free subgroup, while the level of TBIL (P=0.002) was lower than that in antipsychotics-naïve/free subgroup. 77 schizophrenic patients in acute stage were followed up, and there was no significant difference in level of UA before and after treatment, but levels of ALB (P<0.001) and TBIL (P<0.001) decreased significantly after the treatment.
Conclusion: This study demonstrated that the dysfunction of peripheral non-enzymatic anti-oxidation system might be involved in the pathogenesis of schizophrenia.

Abstract

Background The standard diagnostic work-up for hand and wrist fractures consists of history taking, physical examination and imaging if needed, but the supporting evidence for this work-up is limited. The purpose of this study was to systematically examine the diagnostic accuracy of tests for hand and wrist fractures. Methods A systematic search for relevant studies was performed. Methodological quality was assessed and sensitivity (Se), specificity (Sp), accuracy, positive predictive value (PPV) and negative predictive value (NPV) were extracted from the eligible studies. Results Of the 35 eligible studies, two described the diagnostic accuracy of history taking for hand and wrist fractures. Physical examination with or without radiological examination for diagnosing scaphoid fractures (five studies) showed Se, Sp, accuracy, PPV and NPV ranging from 15-100%, 13-98%, 55-73%, 14-73% and 75-100%, respectively. Physical examination with radiological examination for diagnosing other carpal bone fractures (one study) showed a Se of 100%, with the exception of the triquetrum (75%). Physical examination for diagnosing phalangeal and metacarpal fractures (one study) showed Se, Sp, accuracy, PPV and NPV ranging from 26-55%, 13-89%, 45-76%, 41-77% and 63-75%, respectively. Imaging modalities of scaphoid fractures showed predominantly low values for PPV and the highest values for Sp and NPV (24 studies). Magnetic Resonance Imaging (MRI), Computed Tomography (CT), Ultrasonography (US) and Bone Scintigraphy (BS) were comparable in diagnostic accuracy for diagnosing a scaphoid fracture, with an accuracy ranging from 85-100%, 79-100%, 49-100% and 86-97%, respectively. Imaging for metacarpal and finger fractures showed Se, Sp, accuracy, PPV and NPV ranging from 73-100%, 78-100%, 70-100%, 79-100% and 70-100%, respectively. Conclusions Only two studies were found on the diagnostic accuracy of history taking for hand and wrist fractures in the current review. Physical examination was of moderate use for diagnosing a scaphoid fracture and of limited use for diagnosing phalangeal, metacarpal and remaining carpal fractures. MRI, CT and BS were found to be moderately accurate for the definitive diagnosis of clinically suspected carpal fractures.
Individual and healthcare system factors influencing antenatal care attendance in Saudi Arabia
Authors: Alanazy Wdad , Brown Amy 
Published: December 2019

Abstract
Background The World Health Organisation recommends women have at least 4 antenatal care visits (ANC) during a low risk pregnancy. However, in Saudi Arabia, many mothers miss these appointments placing their health and that of their baby at risk. Limited research exploring why this is happening usually focuses on low maternal education or personal barriers such as lack of transport. The aim of the current research was therefore to understand what factors at the individual and healthcare systems level were associated with missing antenatal care in Saudi Arabia.Methods Two hundred and forty two pregnant women in their third trimester completed a questionnaire examining their care attendance alongside barriers to attending care. These included maternal demographic background, health literacy, personal barriers, health care system factors and staff communication).Results Over half of women had missed at least one appointment and a third had delayed their care. Mothers who had missed appointments blamed health care system factors such as poor clinic facilities and waiting times. Attending care was not associated with maternal education or literacy. However perceptions of staff communication, consistency and care were lower amongst those who had missed at least one appointment.Conclusions Although in previous research health professionals believe it is maternal education that leads to poor attendance, in our sample at least, it is in fact perceptions of staff communication that affect attendance. Making changes at the health care level e.g. through adapting clinic times and investing in staff training may increase antenatal care attendance in Saudi Arabia.

Published: December 2019

Abstract
Background: Glycine soja is a halophytic soybean native to saline soil in Yellow River Delta, China. Photosystem I (PSI) performance and the interaction between photosystem II (PSII) and PSI remain unclear in Glycine soja under salt stress. This study aimed to explore salt adaptability in Glycine soja in terms of photosystems coordination. Results: Potted Glycine soja was exposed to 300 mM NaCl for 9 days with a cultivated soybean, Glycine max , as control. Under salt stress, the maximal photochemical efficiency of PSII (Fv/Fm) and PSI (△MR/MR 0 ) were significantly decreased with the loss of PSI and PSII reaction center proteins in Glycine max , and greater PSI vulnerability was suggested by earlier decrease in △MR/MR 0 than Fv/Fm and depressed PSI oxidation in modulated 820 nm reflection transients. Inversely, PSI stability was defined in Glycine soja , as △MR/MR 0 and PSI reaction center protein abundance were not affected by salt stress. Consistently, chloroplast ultrastructure and leaf lipid peroxidation were not affected in Glycine soja under salt stress. Inhibition on electron flow at PSII acceptor side helped protect PSI by restricting electron flow to PSI and seemed as a positive response in Glycine soja due to its rapid recovery after salt stress. Reciprocally, PSI stability aided in preventing PSII photoinhibition, as the simulated feedback inhibition by PSI inactivation induced great decrease in Fv/Fm under salt stress. In contrast, PSI inactivation elevated PSII excitation pressure through inhibition on PSII acceptor side and accelerated PSII photoinhibition in Glycine max , according to the positive and negative correlation of △MR/MR 0 with efficiency that an electron moves beyond primary quinone and PSII excitation pressure respectively. Conclusion: Therefore, photosystems coordination depending on PSI stability and rapid response of PSII acceptor side contributed to defending salt-induced oxidative stress on photosynthetic apparatus in Glycine soja . Photosystems interaction should be considered as one of the salt adaptable mechanisms in this halophytic soybean.
