Study Design: Retrospective clinical study. Objective: We evaluated the relationship between cervical sagittal alignment parameters and clinical status in patients with cervical myelopathy and analyzed the effect of cervical sagittal balance on cervical laminoplasty. Methods: Patients with cervical myelopathy (n = 110) who underwent laminoplasty were included in this study. The relationship between cervical sagittal alignment parameters and clinical status was evaluated. The changes in radiographic cervical sagittal parameters and clinical status 2 years after surgery were compared between patients with preoperative C2-7 SVA ≥35 mm (group A) and those with preoperative C2-7 SVA <35 mm (group B). Results: Preoperatively, C2-7 SVA had no correlation with defined health-related quality of life evaluation scores. At 2-year follow-up, the improvement in SF-36 physical component summary was significantly lower in group A than in group B. The postoperative change of C2-7 SVA did not significantly differ in 2 groups. Patients in group A maintained cervical regional balance after laminoplasty but experienced extensive postoperative neck pain. Conclusions: Our patients with a C2-7 SVA of ≥35 mm maintained cervical regional balance after laminoplasty and their improvement in myelopathy was equivalent to that in patients with a C2-7 SVA of <35 mm. However, the patents with a C2-7 SVA of ≥35 mm experienced severe postoperative neck pain. C2-7 SVA is a parameter worth considering because it can lead to poor QOL and axial neck pain after laminoplasty.

Abstract Objective Posterior open-door laminoplasty (PODL) is a common procedure for treating multilevel cervical spondylotic myelopathy (MCSM). Little information is available regarding the cervical sagittal balance and surgical efficacy of PODL when securing with different methods. Therefore, this study aims to investigate the clinical outcomes and the changes in cervical sagittal parameters and balance associated with PODL secured with titanium miniplates vs anchors. Method A retrospective analysis was performed on the clinical data of 79 patients with MCSM who were treated in our institution from January 2015 to December 2016. Among them, 42 patients were treated by PODL secured with titanium miniplates (group A) and 37 patients by PODL secured with anchors (group B). Surgical time, intraoperative blood loss, hospital stay, hospitalized cost, VAS scores of neck pain, JOA scores, neck disability index (NDI), and improvement rate of spinal neurological function (IRNF) were recorded before surgery and at 12 months after surgery. Before surgery, at 1 month and 2 years after surgery, the following radiological parameters were recorded and compared on the lateral cervical X-ray images: the distance from the vertical axis of C2 sagittal plane to the posterior superior edge of C7 (C2-7 SVA), the inclusion angle of tangent between C2 and C7 trailing edge (C2-7 Cobb angle), and the intersection angle between the upper edge of T1 and the horizontal line (T1 Slope). Result Comparing the two groups, there were no significant differences in surgical time, intraoperative blood loss, hospital stay, VAS, JOA, and NDI scores before surgery (P > 0.05); however, the hospitalized cost of group A were much higher than those of the group B (P < 0.05). At 2 years after surgery in the two groups, there was a significant reduction in VAS and NDI scores (P < 0.05), and JOA scores increased significantly (P < 0.05). In addition, there were no significant differences in VAS, JOA and IRNF between the two groups (P > 0.05); however, NDI scores of group A were better than those of group B (P < 0.05). In radiological parameters, before surgery, the two groups showed no significant differences in C2-7 SVA, C2-7 Cobb angle, and T1 slope (P > 0.05); however, after surgery, C2-7 SVA and T1 slope increased (P < 0.05), while C2-7 Cobb angle decreased (P < 0.05). At 2 years after surgery, the two groups did not differ significantly in C2-7 Cobb angle and T1 slope (P > 0.05), while C2-7 SVA of group A was superior to that of group B (P < 0.05). The difference value of C2-7 SVA measured before and after surgery was correlated negatively with that of NDI scores (P < 0.05). Conclusion PODL secured with titanium miniplates or anchors achieved good clinical efficacy in the treatment of MCSM. However, the patients with miniplates feel a better cervical functional status, while those with anchors spend less on hospitalization. Both methods lead to anteversion of cervical spine, but cervical sagittal balance after miniplates is better than that of anchors.

The aim of the study. Assess the importance of pregravid preparation and outcomes of pregnancy and childbirth, depending on the reproductive attitudes of women in the city of Omsk. Materials and methods. The study included 92 women who were divided into groups: group A (n=43) - women whose pregnancy was planned; group B (n=49) - women whose pregnancy occurred accidentally. Each group was divided into subgroups depending on age: from 18 to 30 and from 31 to 49 years. For each patient included in the study, a specially designed map was filled out. These patients were interviewed at the City Clinical Perinatal Center. Results. Comparative analysis revealed the relationship between the reproductive settings of women of childbearing age and the peculiarity of the course of pregnancy and childbirth in these patients. Summary. The majority of women of fertile age are married: in subgroup AA - 25 (96.2%), AB - 13 (76.5%), BA - 25 (92.6%), BB - 20 (91.0%). The predominant number of women of fertile age have one or more abortions: in subgroup AA - 12 (46.2%), AB - 6 (35.3%), in subgroups of comparison BA - 8 (29.6%), BB - 6 (27.3%). More than half of the women of fertile age surveyed have a history of untreated cervical pathology (from 40.8% to 64.7%). The course of pregnancy in women planning pregnancy in most cases proceeded without complications: in subgroup AA - 13 (50.0%), AB - 11 (64.7%). The most common cause of complicated pregnancy in women whose pregnancy occurred accidentally is the threat of spontaneous miscarriage: in subgroup BA - 15 (55.6%), BB - 16 (72.7%). The uncomplicated course of labor more often [subgroup AA - 19 (73.0%), AB - 12 (70.6%)] was observed in women whose pregnancy was planned and they were motivated to give birth to a healthy child.

Abstract Background A few people infected by the coronavirus become seriously ill, while others show little to no signs of the symptoms, or are asymptomatic. Recent researches are pointing to the fact that the ABO blood group might play an important role in a person’s susceptibility and severity of COVID-19 infection. Aim of the study: try to understand the relationship between ABO groups and COVID-19 (susceptibility and severity). Results A total of (507) patients were included in this study. The study population was divided based on the ABO blood group into types A+, A−, B+, AB, O+, and O−. Blood group A was associated with high susceptibility of infection: group A, 381 (75.1%); and less common in group O, 97 (19.2%), group B, 18 (3.5%), and group AB, 11 (2.2%). The severity of COVID-19 infection was common in non-blood group O where (20 (7.1%), 4 (26.7%), 2 (11%), and 1 (9%) in type A+, A−, B+, and AB, respectively), while in type O 3.1%. And mechanically ventilated patients were 22 (5.9%), 2 (13.4%), 2 (11.1%), and 1 (1%). Mortality was high in blood groups A and B, 16 (4.37%) and 1 (5.5%), respectively, while in blood group O, it was 1%. Conclusion The incidence, severity, and mortality of COVID-19 were common in non-blood group O. While blood group O was protected against COVID-19.

The first Dutch outbreak due to Clostridium difficile ribotype 027 was observed in mid-2005; by the end of that year, eight hospitals were affected. To study the relationship between hospital-wide antibiotic use and the incidence of 027-linked C. difficile-associated disease (CDAD) three study groups were made: group A, all eight hospitals with an 027-associated epidemic; group B, five of a total of six hospitals with occasional 027 cases, without an increase in CDAD; and group C, ten randomly selected hospitals with no reported 027 epidemics or isolated 027 cases. Quarterly data on CDAD incidences, hygiene measures and the use of fluoroquinolones, second- and third-generation cephalosporins, extended-spectrum penicillins, penicillins with beta-lactamase inhibitors, carbapenems, lincomycins and macrolides were collected for 2004 and 2005, and divided into pre-epidemic and epidemic periods. Using a multilevel Poisson regression analysis, CDAD incidence was linked to antibiotic use in the previous quarter and to certain hygiene measures. In the pre-epidemic period, the total use of the studied antibiotics was comparable between affected and unaffected hospitals. Higher use of second-generation cephalosporins, macrolides and all of the studied antibiotics were independently associated with a small increase in CDAD incidence [relative risk (95 % confidence interval): 1.14 per increase of 100 defined daily doses per 10 000 bed days (1.06–1.23), 1.10 (1.01–1.19) and 1.02 (1.01–1.03), respectively]. However the effect was too small to predict which hospitals might be more prone to 027-associated outbreaks.

The relationship between portal tributary blood flow (PBF) and hepatic arterial blood flow (HAF) was studied in awake, unrestrained rats with the radiolabeled microsphere technique. Six distinct patterns of response emerged. In group A (PBF+, HAF 0), ethanol, acetate, glucagon, prostacyclin, and a mixed diet increased PBF without a change in HAF; in group B (PBF+, HAF+), adenosine and histamine increased both PBF and HAF; in group C (PBF 0, HAF+), isoflurane and triiodothyronine did not change PBF but increased HAF; and in group D (PBF-, HAF+), halothane and vasopressin decreased PBF and increased HAF. Acute partial portal vein ligation decreased PBF (56%) and increased HAF (436%). Hypoxia (7.5% O2) decreased PBF (28%) and increased HAF (110%). In group E (PBF+, HAF-), acute hepatic artery ligation increased PBF (35%) and reduced HAF (74%), while in group F (PBF-, HAF-), thyroidectomy reduced PBF and HAF (36 and 47%, respectively). All blood flow responses were accompanied by the expected changes in both portal tributary and hepatic arterial vascular resistances. The data suggest that the portal and hepatic arterial vascular territories have regulatory mechanisms that allow for independent changes.

Cervical Spine Dysfunction

Background: Cervical spine dysfunction is a cause of neck pain. The cause for it is believed to be a disorder (most likely malalignment) of the pain-sensitive facet joints (which may also be due to disc disruption). Dysfunction can also cause secondary muscle spasm, which can may lead to more pain and stiffness. Objective: To find the effectiveness of SNAGs and scapular strengthening exercises in the patients with chronic cervical dysfunction. To find the Neck disability index (NDI) score difference between the functional activities of experimental group and conventional treatment group. Methodology: According to inclusion and exclusion criteria a prior to the study, the principal researcher explained the procedures to all the subjects and inform consent obtained, 30 subjects taken through Random block design and numbering was done for all the subjects. All the odd numbers in one group and all the even numbers in another group are allocated by random table where each group had 15 subjects. The collected data was tabulated and analyzed using descriptive and inferential statistics. To all parameters mean and standard deviation (SD) were used. Paired t-test was used to analyze significant changes between pre-test and post-test measurements. Unpaired t-test was used to analyze significant changes between two groups. Result: rom statistical analysis made with the quantitative data revealed statistically significant difference between the Group A and Group B, and also within the group. The Posttest mean value of Neck Disability Index (NDI) in group A is 12.00 and in group B is 13.80. This shows that Neck Disability Index (NDI) in Group B disability value were comparatively more than Group A disability value, P<0.0001. Conclusion: This study shows better improvement in reducing cervical spine dysfunction (neck pain) by scapular strengthening exercise than resisted neck isometrics. Both the techniques can be used in clinical practice.

Background: Whiplash has been suggested to cause chronic symptoms and long term disability. This study was designed to assess long term function after whiplash injury. Material & Methods: A random sample of patients in the outpatient clinic was interviewed, questionnaire completed and clinical examination performed. Assessment was made of passive cervical range of movement and Visual Analogue Scale pain scores. One hundred and sixty-four patients were divided into four different groups including patients with no whiplash injury but long-standing neck pain (Group A), previous symptomatic whiplash injury and long-standing neck pain (Group B), previous symptomatic whiplash injury and no neck symptoms (Group C), and a control group of patients with no history of whiplash injury or neck symptoms (Group D). Results: Data was analyzed by performing an Independent samples t-test and ANOVA, with level of significance taken as p<0.05. Comparing the four groups using a one-way ANOVA showed a significant difference between the groups (p<0.001). There were significant differences when comparing mean ranges of movement between Group A and Group D, and between Group B and Group D. There was no significant difference between Group C and Group D. similar differences were also seen in the pain scores. Conclusion: We conclude that osteoarthritis in the cervical spine, and whiplash injury with chronic problems cause a significantly decreased cervical range of movement with a higher pain score. Patients with shorter duration of whiplash symptoms appear to do better in the long-term.
