ABSTRACT

BACKGROUND: The incidence rate of degenerative spinal deformity (DSD) has gradually increased in the elderly. Currently, the relationship between the functional status of trunk muscle and the spinal-pelvic parameters of DSD patients remains unclear.

OBJECTIVE: This paper aims to explore the relationship between the two factors and provide new clues for exploring the mechanism of the occurrence and development of DSD.

METHODS: A total of 41 DSD patients treated in our hospital (DSD group) and 35 healthy volunteers (control group) were selected. Muscle strength was evaluated using an IsoMed-2000 isokinetic dynamometer, and the trunk flexor and extensor peak torque (PT) of subjects was measured at a low, medium, and high angular velocity of 30∘/s, 60∘/s, and 120∘/s, respectively. Hand grip strength (HGS) was assessed using an electronic grip dynamometer and Surgimap software was used to measure the spinal-pelvic parameters, including the sagittal vertical axis (SVA), thoracic kyphosis (TK), lumbar lordosis (LL), sacral slope (SS), pelvic tilt (PT), pelvic incidence rate (PI), and PI-LL, and the relationship between trunk muscle function and various parameters was analyzed.

RESULTS: Under the three angular velocities, the flexor and extensor PT values in the DSD group were lower than those in the control group, and only the extensor PT showed a statistically significant difference (P< 0.05). There was no significant difference in HGS between the two groups (P> 0.05). In the DSD group, the extensor PT at 30∘/s was significantly negatively correlated with SVA (P< 0.05). At 60∘/s and 120∘/s, the extensor PT was significantly negatively correlated with SVA and PT (P< 0.05).

CONCLUSION: Trunk extensor strength is significantly lower in DSD patients than in normal controls. The decline in trunk extensor strength in DSD patients is a type of local muscle dysfunction more closely related to the deformity, which is likely involved in the compensatory mechanism of DSD and may reflect the overall imbalance of the trunk.

ABSTRACT

PURPOSE: This research was planned to follow the healing process of the oral mucosa in patients in intensive care with an “Impaired Oral Mucous Membrane Integrity” nursing diagnosis based on the “NOC (1100) Oral Health Assessment” outcome criteria.

METHOD: This study, which was planned in a methodological and descriptive type of research, was carried out with 50 patients who were hospitalized in the intensive care clinic of a state hospital between June and December 2022, with a nursing diagnosis of “Impaired Oral Mucous Membrane Integrity.” Data were collected using a Patient Information Form and the “NOC (1100) Oral Health Evaluation Scale” for the nursing outcomes classification. In the analysis of the data descriptive statistical methods, Pearson correlation test, Friedman test as well as Cohen’s kappa test were used to evaluate the agreement between two independent observers.

FINDINGS: In the study, content validity index value of the NOC scale was calculated to be 0.90. The examination of the participants’ mean scores on the NOC (1100) Oral Health Assessment Scale showed that there were statistically significant differences in terms of the repeated evaluations, except for the NOC indicators of “Oral mucosal integrity,” “Gum integrity,” and “Tooth integrity” (p < 0.01). No statistically significant correlation was found between the mean NOC scale scores of the patients according to the variables of age, body mass index, mechanical ventilation time, and length of stay in the intensive care unit (p > 0.05).

CONCLUSIONS: The findings showed that the Turkish version of NOC (1100) Oral Health Assessment Scale was a valid tool for monitoring the healing process of the oral mucosa in patients in intensive care.

IMPLICATIONS OF NURSING PRACTICE: With the use of NOC (1100) Oral Health Assessment Scale, a common language will be formed in the evaluation for monitoring the healing process of the oral mucosa in nursing care.

ABSTRACT

BACKGROUND: Injuries and sudden death during the cross-country (XC) phase of eventing have raised interest in the frequency and types of cardiac arrhythmias occurring in these equine athletes.

OBJECTIVES: To characterise the frequency and types of rhythm disturbances and examine possible risk factors for premature depolarisations (PDs) occurring during the XC phase of United States Eventing Association (USEA) and Fédération Equestre Internationale (FEI)-sanctioned events.

STUDY DESIGN: Prospective, cross-sectional study.

METHODS: Continuous electrocardiographic (ECG) recordings were obtained from horses prior to, during and immediately following the XC competition. Physiological rhythms pre-XC were included in the arrhythmia group for analysis. The frequency of PDs was calculated for all horses, as well as by division. PDs were categorised by complexity (singles, couplets, triplets, complex) and variably grouped for statistical analysis. Multiple logistic regression was used to identify risk factors for the presence of specific cardiac arrhythmia groupings during XC.

RESULTS: PDs were identified in 42/75 horses (56% [45, 67]) during XC. Horses competing in the upper divisions of eventing had higher odds for having any PD during XC compared to the lower divisions (OR = 17.5 [4.3, 72.01], p = 0.006). The amount of time the heart rate (HR) was greater than 199 beats per minute (BPM) was associated with more complex arrhythmias (triplets, salvos and tachyarrhythmias) (OR = 1.01 [1.0, 1.02], p = 0.005). An arrhythmia at rest (physiological or PD) was associated with arrhythmia in the early recovery period (OR = 3.5 [1.1, 10.8], p = 0.03).

MAIN LIMITATIONS: Convenience sampling and technical challenges of continuous ECG recordings under competition settings limited the number of enrollments.

CONCLUSIONS: PDs were seen in a high percentage of horses during the XC competition. Upper levels and time the HR was greater than 199 BPM were related to PD presence and complexity.

ABSTRACT

Objective To investigate the relationship between disease courses and severity and monocyte subsets distribution and surface CD31 intensity in patients of hemorrhagic fever with renal syndrome (HFRS). Methods Peripheral blood samples from 29 HFRS patients and 13 normal controls were collected. The dynamic changes of classical monocyte subsets (CD14⁺⁺CD16^–), intermediated monocyte subsets (CD14⁺⁺CD16⁺) and non-classical monocyte subsets (CD14⁺CD16⁺⁺) and the mean fluorescent intensity (MFI) of CD31 on monocyte subsets were detected by multiple-immunofluorescent staining and flow cytometry. Results In acute phase of HFRS, the ratio of classical monocyte subsets to total monocytes was dramatically decreased compared to convalescent phase and normal control. It was still much lower in convalescent phase compared to normal controls. The ratio of classical monocyte subsets to total monocytes were decreased in HFRS patients compared to that in normal control, whereas there was no difference between severe/critical groups and mild/moderate groups. On the contrary, the ratio of intermediate monocyte subsets to total monocytes in acute phase of HFRS was significantly increased compared to convalescent phase and normal control. The ratio of intermediate monocyte subsets to total monocytes were increased in HFRS patients compared to that in normal control, whereas no difference was found between severe/critical groups and mild/moderate groups. Phases or severity groups had no difference in ratio of non-classical monocyte subsets to total monocytes. Additionally, the ratio of classical monocyte subsets had a tendency to decline and that of intermediate monocyte subsets showed an increase both to total monocytes between the acute and convalescent phases in 11 HFRS patients with paired-samples. Moreover, in acute phase of HFRS, the mean fluorescent intensity (MFI) of CD31 on three monocyte subsets all decreased, specifically classical monocyte subsets showed the highest MFI of CD31 while the normal control reported the highest MFI of CD31 in non-classical monocyte subsets. In convalescent phase, the MFI of CD31 on classical and intermediated monocyte subsets were both lower than that of normal control, while MFI of CD31 was still significantly lower than normal control on non-classical monocyte subsets. Finally, MFI of CD31 on classical and intermediated monocyte subsets in severe/critical group were both lower than those in mild/moderate group, showing no statistical difference in MFI of CD31 on non-classical monocyte subset across groups of different disease severity. Conclusion The ratio of classical and intermediated monocyte subsets to total monocytes are correlated with the course of HFRS, and so are the surface intensity of CD31 on these monocyte subsets with the disease course and severity. The surface intensity of CD31 on non-classical monocyte subsets, however, is correlated only with the course of the disease. Together, the underlying mechanisms for the observed changes in monocyte subsets in HFRS patients should be further investigated.

ABSTRACT

BACKGROUND: Dentistry is reported as a very-high-risk profession for COVID-19 contagion. A lack of face-to-face education and poor information during the COVID-19 pandemic may have impacted dental students.

OBJECTIVES: We aimed to evaluate the effects of the COVID-19 pandemic on career plans and self-perception of knowledge levels in undergraduate dental students.

MATERIAL AND METHODS: In this multicenter cross-sectional study, a multiple-choice survey was completed by dental students of Near East University (NEU) in North Nicosia and University of Kyrenia (UoK) in the Turkish Republic of Northern Cyprus (TRNC), and Erciyes University (ERU) in Kayseri, Turkey, in 2020. The χ2 tests were used to determine statistically significant differences.

RESULTS: Of the 755 students that participated in the study, 66% declared fear of being at risk for contagion. More than half of the students reported not having sufficient knowledge about occupational infections and methods for protection, and the percentages were significantly higher in female and preclinical students. Utilization of credible publications, guidelines (57% compared to 34%, p < 0.001) and online education (19% compared to 8%, p < 0.001) were significantly higher in students claiming to have adequate knowledge. Eleven percent of the students thought about dropping out of dental education because of the COVID-19 pandemic. These students exhibited a markedly increased fear of being at risk for contagion because of the COVID-19 pandemic (80% compared to 64%, p = 0.011). Seventy-six percent of the students were aiming for a dental specialty. Eighteen percent changed their desired specialty, and 25% were in search of a specialty that they believed required fewer close contact procedures.

CONCLUSIONS: It is crucial to prepare students for the next possible outbreak using the knowledge gained during this pandemic by modifying the dental curriculum and providing credible information and psychological support to guide dental students in building a healthy career path.

ABSTRACT

BACKGROUND: The survival rate, marginal bone loss and soft tissue health of the Ankylos implants and the balanced base abutments in all-on-four or six implant restoration of edentulous or terminal dentition patients has not been reported in the clinical research.

PURPOSE: This retrospective study aimed to evaluate the Ankylos implants and the balanced base abutments in all-on-four or six implant restoration of edentulous or terminal dentition patients after 1-8 years of follow-up.

MATERIALS AND METHODS: A retrospective study was conducted based on the medical records of 33 patients who received all-on-four or six treatments from April 2014 to May 2020. Four radiographic examinations [immediate postoperative (T0), definitive restorations (T1), 1-3 years after prosthetic restorations (T2), and more than 3 years after prosthetic restorations (T3)] were obtained to evaluate vertical bone height (VBH). We also calculated the survival rate and examined the condition of soft tissue with this implant system in edentulous or terminal dentition patients. Three-level linear model analyses were used to explore potential risk factors for VBH changes on the mesial and distal sides. The generalized linear model was used to analyze the influencing factors of BOP and plaque.

RESULTS: A total of 218 implants were included in this study. The cumulative survival rate of the implants was 97.25% before the definitive prosthesis, 96.33% within 3 years of follow-up and 95.32% after more than 3 years of follow-up. The mean ± standard deviation (SD) bone losses of the VBH were 0.27 ± 0.05 mm (T1-T3) on the mesial side and 0.49 ± 0.06 mm (T1-T3) on the distal side. During 1-8 years of follow-up, the height and angle of the abutment (p < 0.001), the mandible implant site (p < 0.001), the length of the implant (p = 0.014 < 0.05) and age (p = 0.029 < 0.05) showed statistically significant effects on vertical mesial bone height (VMBH) and vertical distal bone height (VDBH). The risk of BOP among participants who brushed three times a day was lower than those who brushed less than three times. The plaque risk of short abutment height was higher than the long abutment.

CONCLUSION: The current study showed that the Ankylos implants with the balanced base abutments in all-on-four or six implants treatment is a viable and predictable option with a high survival rate and low marginal bone loss in edentulous or terminal dentition patients. VBH around the implants was strongly associated with the mandible implant site, abutment height and angle, the length of the implant and age. Moreover, teeth-brushing times and abutment height significantly affect soft tissue health.

ABSTRACT

Objective: To investigate the clinical efficacy of dynamic cross screw system (FNS) for femoral neck fractures in young and middle-aged patients with posterior medial comminution. Methods: A retrospective cohort study. Clinical data of 197 young and middle-aged patients with femoral neck fractures accompanied by posterior medial comminution treated with closed reduction FNS and internal fixation with anti-rotation cannulated screws in Beijing Luhe Hospital, Beijing Jishuitan Hospital and Beijing Tongren Hospital from October 2019 to October 2021 were analyzed retrospectively. According to different surgical methods, the patients were divided into two groups. There were 102 patients in the FNS group, included 55 males and 47 females with a mean age of (40.49±19.79) years; and there were 95 patients in the FNS plus anti-rotation hollow screw group (combined group), included 51 males and 44 females with an average age of (40.03±18.82) years. All patients were followed-up for at least 1 year after surgery. The general clinical data, surgical conditions and Harris score of the hip joint at the last follow-up of the two groups were compared. And the clinical efficacy of the two surgical schemes were evaluated and compared. After surgery, routine X-ray and CT examinations were performed to evaluate the fracture reduction and internal fixation, and the shortening of the femoral neck on the affected side was compared to that of healthy side according to the Zlowodzki method. Results: At the last follow-up, the incidence of fracture reduction loss, screw resection and coxa vara in the combined group were all significantly lower than those in the FNS group [10 (10.5%) vs 28 (27.4%), 1 (1.0%) vs 7 (6.8%) and 9 (9.4%) vs 21 (20.5%), respectively, all P<0.05]. The incidence of nonunion and necrosis of the femoral head in the combined group were both lower than those in the FNS group, but there was no significant difference between two groups (both P>0.05). The postoperative mild, moderate and severe femoral neck shortening in the combined group were all lower than those in the FNS group, and the difference were not statistically significant (all P>0.05). At the last follow-up, the Harris score in the combined group was 84.60±2.08, and it was higher than that in the FNS group (79.57±4.31), but the difference was not statistically significant (P=0.403). Conclusion: FNS plus supporting hollow screw has a good clinical effect on femoral neck fractures in young and middle-aged adults with posterior medial comminution.

ABSTRACT

Objective: To investigate the clinical efficacy of bilateral gluteal muscle contracture treated with inside-out iliotibial band release under arthroscopy in the supine position. Methods: A prospective non-randomized controlled trial. Forty-six patients admitted to the Department of Sports Medicine, Senior Department of Orthopedics, the Fourth Medical Center of PLA General Hospital from April 2021 to August 2022 for bilateral gluteal muscle contracture and proposed surgical treatment were enrolled. The subjects were divided into two groups according to the preferred surgical protocols of the patients: the supine position group was treated with inside-out iliotibial band release under arthroscopy in the supine position, and the operation in lateral position group was carried out with outside-in iliotibial band release under arthroscopy in the lateral position. The total duration of non-surgical operations and the total duration of surgical operations were recorded for all patients. The gluteal muscle contracture disability scale within 3 days before surgery and at least 2 months after surgery were compared between the two groups, and the occurrence of complications between the two groups was compared too. Results: There were 26 cases in the supine position group, 11 males and 15 females with a mean age of (31.8±7.3) years; and there were 20 cases in the lateral position group, 7 males and 13 females with a mean age of (30.6±6.3) years. The differences in gender, age, body mass index (BMI) and postoperative follow-up time between the two groups were not statistically significant (all P>0.05). The total duration of non-surgical operations was shorter in the supine position group than in the lateral position group [(47.9±10.4) min vs (63.9±7.5) min, P<0.001]. There was no statistically significant difference in the total duration of surgical operations between the supine position group and the lateral position group [31.0(27.0, 43.5) min vs 33.0(24.8, 38.0) min, P>0.05]. The postoperative gluteal muscle contracture disability scales were significantly improved in both the supine position and lateral position groups when compared with those before the operation [93.0 (85.0, 98.0) vs 61.0 (50.5, 66.8), P<0.001 and 88.5±6.9 vs 63.6±9.6, P<0.001, respectively]. There was no statistically significant difference in the gluteal muscle contracture disability scale between the supine position and lateral position groups before and 2 months after surgery [59.3±11.9 vs 63.6±9.6 and 93.0 (85.0, 98.0) vs 89.5(84.0, 94.8), both P>0.05, respectively]. Two patients in each group developed subcutaneous hematoma after surgery, and all of them resolved within 2 weeks after surgery, the difference in complication incidence rate was not statistically significant (P>0.05). No postoperative complications such as fat liquefaction in the operated area, infection, decreased hip abductor muscle strength or nerve injury in the lower extremity were observed in both groups. Conclusion: The treatment of bilateral gluteal muscle contracture by inside-out iliotibial band release under arthroscopy in the supine position can effectively improve clinical efficiency, with definite efficacy, and it is an operative program worth promoting.

ABSTRACT

Objective: To investigate the diagnostic value of quantitative parameters of synthetic magnetic resonance imaging (SyMRI) in the grade of supraspinatus tendon injury. Methods: Ninety-seven patients with clinical definite of supraspinatus tendon injury from July 2021 to July 2022 in General Hospital of Ningxia Medical University were prospectively collected (case group), including 54 males and 43 females, with an age of 29 to 56 (37.4±9.6) years. According to the results of shoulder arthroscopy, the case group were divided into three subgroups included tendinopathy group (37 cases, grade Ⅱ), partial tear group (34 cases, grade Ⅲ) and complete tear group (26 cases, grade Ⅳ). During the same period, 28 normal rotator cuff volunteers without supraspinatus tendon injury were recruited (control group), including 16 males and 12 females, aged 23 to 49 (36.1±7.2) years, and marked as grade Ⅰ. All the subjects underwent MRI scan of articulatio humeri included T₁-weighted imaging(T₁WI) fast spin echo(FSE) sequences in axial view, T₂-weighted imaging(T₂WI) fat suppression(FS) sequences in axial view, T₂WI FS sequences in oblique coronal view, proton density-weighted (PDW) imaging in oblique sagittal view and SyMRI in oblique coronal view. The supraspinatus tendon was divided into lateral, medial and middle subregions according to its shape in oblique coronal T₂WI view, two radiologists measured the T₁, T₂ and PD values of the supraspinatus tendon. The interclass correlation coefficient (ICC) were used to compare the consistency between and within observers. One-way analysis of variance or Kruskal-Wallis H test were used to compare the differences of quantitative parameters in different grades, the multivariate logistic regression model was used to analyze the risk factors of supraspinatus tendon injury grade, and the receiver operating characteristic (ROC) curves and area under curve (AUC) was drawn and calculated to evaluate the diagnostic efficacy. The Spearman correlation was used to analyze the correlation between the quantitative values and grades of supraspinatus tendon injury. Results: The ICC values of T₁, T₂ and PD values for the three subregions of the supraspinatus tendon were greater than 0. 700. The differences of T₁ values in the lateral subregion, T₂ values in the lateral and middle subregions were statistically significant in the overall comparison across different grades (all P<0. 001).The differences of T₁ values in the middle and medial subregions, T₂ values in the medial subregion and PD values in the lateral, middle and medial subregions were not statistically significant in the overall comparison of different grades (all P>0. 05). Multiple logistic regression model analysis showed that T₂ values in the lateral and middle subregions were related factors for the grade of supraspinatus tendon injury[ OR (95%CI):1.123 (1.037-1.216), 0.122 (1.151-1.197);all P<0.001 ]. The AUC of the T₂ values in lateral subregion diagnosing grade Ⅰ vs grade Ⅳ, grade Ⅱ vs grade Ⅳ and grade Ⅲ vs grade Ⅳ were 0.891(95%CI: 0.801-0.981), 0.797(95%CI: 0.680-0.914), 0.723(95%CI: 0.594-0.853) (all P<0.001), and the AUC of the T₂ values in middle subregion diagnosing grade Ⅰ vs Ⅳ, grade Ⅱ vs Ⅳ, grade Ⅱ vs Ⅲ, and grade Ⅰ vs Ⅲ were 0.946 (95%CI: 0.849-0.989), 0.886 (95%CI: 0.809-0.962), 0.746 (95%CI: 0.631-0.861), 0.843 (95%CI: 0.745-0.941)(all P<0.001). The T₂ values in the lateral and middle subregions were positively correlated with the grade of supraspinatus tendon injury (r=0.542, 0.615; both P<0.001), while T₁ values and T₂ values in the medial subregions were not significantly correlated with the grade of supraspinatus tendon injury (both P>0.05). Conclusion: SyMRI has high clinical application value in the grading of supraspinatus tendon injury, especially T₂ value can be used as an effective quantitative parameter for the grading of supraspinatus tendon injury.
