ABSTRACT

STATEMENT OF PROBLEM: A defective socket is common after tooth extraction in the esthetic zone, but whether an implant can be immediately placed in a defective socket is unclear.

PURPOSE: The purpose of this systematic review and meta-analysis was to summarize relevant studies within the last 20 years on implant survival and changes in soft and hard tissues after immediate implant placement in esthetic areas with socket defects.

MATERIAL AND METHODS: A search was conducted for the relevant studies in the PubMed/Medline, the Cochrane Library, Web of Science, and Embase databases from January 2000 to March 2022. The literature review, data retrieval, and judgment whether the included studies had a risk of bias were handled independently by 2 reviewers, and a single-arm meta-analysis was performed using a statistical software program.

RESULTS: A total of 23 studies evaluating the immediate implant placement of 630 implants (9 studies without a flap and 14 studies with a flap) were included. A 98.1% implant survival rate (95% confidence interval (CI): 96.2%, 100.0%) was determined. Marginal bone loss (MBL) at 6, 12, and ≥24 months were 1.03 mm (95%CI: 1.02, 1.03), 0.72 mm (0.72, 0.73), and 1.15 mm (1.14, 1.16). Gingival recession at 12 months was 0.25 mm (95%CI: 0.17, 0.33). The pink esthetic score (PES) were 12.34 (95%CI: 12.16, 12.52) at 12 months and 12.58 (12.39, 12.76) at ≥24 months.

CONCLUSIONS: Current evidence shows that immediate implant placement into defective sockets in esthetic areas is feasible. Immediate implant placement can have a relatively good therapeutic effect in terms of implant survival rate, MBL, gingival recession, and PES.

ABSTRACT

BACKGROUND: Neurofibromatosis type 1 (NF1) is a rare genetic disorder with a wide range of clinical manifestations, notably neurocutaneous features, that can lead to emotional and physical consequences.

OBJECTIVES: This study assessed the influence of sociodemographic factors and clinical features of the disease on the quality of life of Brazilian individuals with NF1.

METHODS: This is a descriptive cross-sectional study. Data were collected from 101 individuals with NF1 using the Brazilian version of the Impact of NF1 on Quality of Life Questionnaire (INF1-QoL), a form with information on sociodemographic characteristics, and an NF1 visibility self-evaluation scale. The relationship between variables was evaluated through statistical testing, and the significance level was defined as 0.05.

RESULTS: The study included 101 adults with NF1 aged 18 to 59 years, with a mean age of 35.54 years (±9.63) and a female predominance (n = 84, 83.17%). The mean total INF1-QoL score was 10.62 (±5.63), with a median of 10, minimum value of 0, and maximum of 31 points. Two characteristics of the participants were significantly associated with the quality of life: educational level (p = 0.003) and familial history of NF1 (p = 0.019). There was a statistically significant correlation between the INF1-QoL score and the degree of disease visibility (rho = 0.218; p = 0.028).

STUDY LIMITATIONS: Cross-sectional study, conducted with a convenience sample and using self-reported measures.

CONCLUSIONS: The findings support the significant impact of NF1 on quality of life. The authors recommend multidisciplinary follow-up for patients, with adherence to anticipatory clinical care measures, adequate pain control, psychological assistance, and genetic counseling.

ABSTRACT

AIM: This study was carried out to determine the prevalence of pressure injury and risk factors in patients hospitalized in a university hospital’s level 3 intensive care unit.

DESIGN: It is a descriptive, prospective, observational type study.

METHOD: The sample of the study consisted of 176 patients aged 18 and over who were admitted to the intensive care units of a University Hospital for at least 24 h. Patient Information Form and Braden Risk Assessment Scale, Glasgow Coma Scale were used to collect data. IBM SPSS Statistics 20 program was used to analyze the data.

RESULTS: Presence of chronic disease in the development of pressure injury (22.7%), high-risk patients according to the Glasgow Coma Scale (21%), high-risk patients according to the Braden Risk Assessment Scale (84.2%), low hemoglobin (31%), low albumin levels (32.4%) and duration of stay in the intensive care unit until the day of evaluation were found to be independent risk factors (p < 0.05). The prevalence of pressure injury was determined to be 32.4%, and the rate of pressure injury due to medical devices was 7.4%.

CONCLUSION: Pressure injuries are still common in adult intensive care patients. In terms of patient safety, it is important to give more space to care standards and awareness-raising research and training to prevent pressure injuries.

ABSTRACT

OBJECTIVE: To assess the efficacy of the metal artifact reduction algorithm (MARA) of the Cranex 3D cone beam computed tomography (CBCT) device in the detection of peri-implant dehiscence and fenestration around zirconia implants.

STUDY DESIGN: In total, 60 implants were placed in bovine ribs. Dehiscence and fenestration defects were created around the implants, after which 60 CBCT images were obtained with and 60 without activation of MARA. Three radiologists examined the images for the presence of defects. The area under the curve (AUC) from receiver operating characteristic analysis, sensitivity, and specificity were calculated to assess the ability to discriminate the presence vs absence of bone defects. One-way analysis of variance was employed to analyze outcome measures. The significance level was established at 5% (α = 0.05).

RESULTS: AUC values indicated excellent discrimination of dehiscence on images with MARA activation and an excellent to outstanding range of discrimination with MARA deactivation. For fenestration, MARA activation and deactivation both led to outstanding discrimination. Sensitivity and specificity values revealed that activation of MARA was helpful in distinguishing the presence vs. absence of dehiscence, while both MARA conditions were helpful for fenestration. However, there were no statistically significant differences between MARA activation and deactivation for any outcome measure (P >.05).

CONCLUSION: CBCT is suitable for detecting peri-implant defects, but MARA application does not significantly affect peri-implant dehiscence and fenestration detection.

ABSTRACT

INTRODUCTION: Human development includes lots of physical and emotional changes. The human voice depends on age. Voice production is a complex physiological and acoustic phenomenon that depends on many factors such as structure, hormone level, degree of fatigue or nutrition and hydration of the body, systemic diseases, and emotional state. All these factors can be present in anorexia nervosa (AN), such as excessive weight loss, generated hydro-electrolytic changes, nutritional deficiencies, hormonal disturbances in the function of the hypothalamic-pituitary-adrenal axis, the hypothalamic-pituitary-thyroid axis, the hypothalamic-pituitary-ovarian axis, and emotional distress. The prevalence of AN ranges between 0.3% and 3%, and it is the third most common chronic disease affecting adolescent girls. However, voice changes related to AN have not been fully investigated.

OBJECTIVE: The purpose of this study was to evaluate the impact of AN on age-related changes in the voice of adolescent women-before and after puberty, particularly through acoustic analysis. An additional objective was to evaluate estrogen substitution in female patients with AN in order to investigate their effect on voice condition.

MATERIALS AND METHODS: 126 girls diagnosed with AN (15.32 ± 2.12 years, range 12-19, BMI = 14.38 ± 1.67), were assessed for the condition of the voice such as perceptual voice evaluation on the GRBAS scale, maximal phonation time (MPT), laryngoscopy, with special attention to voice acoustic analysis-Multi-Dimensional Voice Program (MDVP). The control group (B) included 93 girls without eating disturbances (aged 12-19, mean age 15.52 ± 2.40, BMI = 21.50 ± 1.54). Perceptual voice assessment, aerodynamic test MPT, and acoustic parameters were analyzed in age groups (≤16 years and >16 years). The human vocal tract is sensitive to sex hormones, so the analysis was carried out in the group up to the age of 16 and above 16 to check possible effects.

RESULTS: GRBAS scale was higher in girls with AN compared to the control group for breathiness (B) (P = 0.0002) and asthenia (A) (P < 0.05). The median GRBAS scale for the older group of anorexic women was the highest (2.0). The mean MPT for group A was significantly lower (15.40 ± 3.51 seconds). Comparing age subgroups there was a prolongation of MPT in the healthy group (in groups ≤16 years and >16 years respectively 21.13 seconds versus 25.40 seconds) and a shortening in the anorectic group (≤16 years versus >16 years: 17.06 seconds versus 14.17 seconds). There was no difference between groups A and C up to 16 years of age, but above 16 years of age appeared (14.17 seconds versus 25.40 seconds). Acoustic analysis revealed lower F0 values in group A and C in older subgroups (215,85 Hz versus 236,01 Hz-statistically significant), as well as between subgroups both groups (A: 251,38 Hz versus 215,85 Hz; C: 248,20 Hz versus 236,01 Hz). A narrowing of the vocal range in girls over 16 years in group A was observed. There were no statistically significant differences in F0 between subgroups ≤16 years in groups A and C (251.38 Hz versus 248.20 Hz). The ENT study found that more than half of the girls (54.55%) over the age of 16 who took hormone supplementation manifested laryngeal structure that was normal for their age, there was no effect of hormone supplementation on any of the MDVP parameters between the drug-taking and non-drug-taking groups.

CONCLUSIONS: The acoustic results of the voice in MDVP measurements in adolescent women with AN are not within the normal range and do not mimic the normal developmental changes of the voice. The most important acoustic characteristics of the voice are changes in the fundamental frequency F0 and the range of the voice tended to be more severe in anorectic women >16 years of age and to increase with age, indicating a possible cumulative effect of malnutrition-related disorders as well as hormonal dysfunctions. MDVP can be considered a simple, non-invasive method of assessing the voice organ in AN. MPT differentiated the study groups well: statistically significant differences were noted both between the groups, as well as between age groups. There was no significant effect of oral hormone supplementation on any parameters of the voice. In conclusion, body mass and fat volume in AN may be related to voice production/physiology, affecting voice quality, voice acoustic parameters, voice aerodynamics, and phonatory range in an age-dependent manner. Future studies are needed to assess the long-term efficacy of estrogen treatment in AN.

ABSTRACT

OBJECTIVE: To systematically evaluate the clinical efficacy and safety of proton-pump inhibitors (PPIs) combined with alginate versus PPIs alone in the treatment of gastroesophageal reflux disease (GERD).

METHODS: Randomised Controlled Trials (RCTs) of PPIs combined with alginate and PPIs alone for the treatment of GERD in PubMed, Embase, and The Cochrane Library were searched and screened, and the risk assessment of bias and statistical analysis were performed using Rev Man 5.4 software.

RESULTS: A total of four RCTs (608 patients) were included. Before and after treatment, the change of heartburn score in the experimental group increased compared with the control group, but the difference was not statistically significant [Standard Mean Difference (SMD)= -0.29, 95%CI (-0.78, 0.19), P > 0.05]; The change of HRDQ heartburn score increased, but the difference was not statistically significant [SMD= -0.40, 95%CI (-1.04, 0.24), P > 0.05]; The number of days without heartburn during the 28-day treatment period increased, but the difference was not statistically significant [OR= 1.16, 95%CI (0.37, 3.61), P > 0.05]; The amount of reflux score increased, but the difference was not statistically significant [SMD= -0.30, 95%CI (-0.71, 0.11), P > 0.05]; The amount of change in HRDQ regurgitation score increased, but the difference was not statistically significant [SMD= -0.05，95%CI （- 1.57，0.17）， P > 0.05]； There was no statistically significant difference in adverse events with treatment [OR= 0.93, 95%CI (0.58, 1.47), P > 0.05].

CONCLUSION: In the treatment of GERD, the efficacy of PPIs combined with alginate is improved compared with PPIs alone, but there is no significant difference, and alginate does not increase the occurrence of adverse events in PPIs treatment. In the future, more subdivisions of GERD subtypes and more high-quality studies are needed to further improve the treatment strategy of GERD-related diseases.

ABSTRACT

INTRODUCTION: Type 2 diabetes mellitus (T2DM) is related to glomerular filtration rate (GFR) impairment, which is one of the main causes of chronic kidney disease. The objective of this study was to identify the risk factors related to GFR in Mexican adults with T2DM, using a validated multiple linear regression model (MLRM), with emphasis in body adiposity, glycemic control, duration of the diabetes and other relevant risk factors.

MATERIALS AND METHODS: A cross-sectional, analytical, and observational study was carried out in 252 adults with a previous diagnosis of T2DM. Body mass index (BMI) and waist circumference (WC) were determined and a fasting blood sample was collected for glucose, creatinine and HbA1c determinations. GFR was calculated with the Cockcroft-Gault equation adjusted for body surface area. Four MLRM were performed to determine the factors related to the GFR; it was evaluated whether these models complied with the statistical assumptions of the linear regression model.

RESULTS: The average age of the participants was 60 ± 12 years, 62.3% of them were women. GFR correlated with BMI and WC; age and duration of the diabetes were associated inversely. Model 4 of the MLRM reported a coefficient of determination of 53.5% where the variables BMI (β = 1.31), male sex (β = -6.01), duration of T2DM (β = -0.57), arterial hypertension (β = -6.53) and age (β = -1.45) were simultaneously and significantly related to the GFR.

CONCLUSIONS: Older age, male sex, longer duration of T2DM and the presence of arterial hypertension were associated with a decrease in the GFR; BMI and WC were directly associated. No effect of glucose and HbA1c on GFR was observed.

ABSTRACT

PURPOSE: Metronidazole, a widely used antimicrobial medication, has been linked to neurologic adverse drug reactions. This study investigates the association between metronidazole use and first-time neurologic events.

METHODS: We conducted a case-time-control study using data from the Danish National Patient Register and the National Prescription Register in years 2013 to 2021. Patients with a first-time diagnosis of encephalopathy, cerebellar dysfunction, or peripheral neuropathy were included. Conditional logistic regression analyses were performed to estimate the risk of neurologic events associated with metronidazole use.

FINDINGS: Out of 476,066 first-time metronidazole prescriptions, the 100-day cumulative incidence of peripheral neuropathy was 0.016%, and 0.002% for cerebellar dysfunction or encephalopathy. In the case-time control study, we identified 17,667 persons with a first-time neurologic event and were included for the analysis. The estimated odds ratio for the combined neurologic events was 0.98 (95% CI, 0.59-1.64, P = 0.95) with no statistically significant association across different subgroups and time windows.

IMPLICATIONS: Our findings suggest that metronidazole-induced neurologic events may be rarer than previously described, and we did not find any consistent or statistically significant association between metronidazole exposure. Nonetheless, clinicians should remain vigilant to potential neurologic risks in patients receiving metronidazole, to ensure its safe and effective use.

ABSTRACT

BACKGROUND: Older adults undergoing total knee arthroplasty may develop chronic pain without effective postoperative pain management. Increasing nurses’ knowledge, changing their attitudes, and developing their pain management self-efficacy could improve the effectiveness of pain management.

AIM: To determine the effectiveness of an online learning program to help registered nurses to manage postoperative pain in older adults undergoing total knee arthroplasty.

DESIGN: A quasi-experimental pre-test-post-test design with intervention and control groups.

METHOD: Six inpatient units were randomly selected at a large tertiary care medical center. Sixty nurses were evenly divided between intervention and control groups to participate in online learning about postoperative pain management in patients undergoing total knee arthroplasty. The content was based on Kolb’s experiential learning theory. Data were collected on nurses’ knowledge and attitudes toward pain management and pain management self-efficacy at baseline and after completion. Data were analyzed using descriptive statistics, chi-square tests, paired t-tests, and independent t-tests.

RESULTS: The knowledge and attitudes about pain management and pain management self-efficacy toward older adults undergoing total knee arthroplasty of nurses in the intervention group significantly improved compared to the baseline and were also significantly higher than in the control group.

CONCLUSIONS: An online learning program improves nurses’ understanding and ability to manage pain in older adults undergoing total knee arthroplasty. This was therefore an effective learning method.

ABSTRACT

INTRODUCTION: Burn injuries among the homeless are increasing as record numbers of people are unsheltered and resort to unsafe heating practices. This study characterizes burns in homeless encounters presenting to US emergency departments (EDs).

METHODS: Burn encounters in the 2019 Nationwide Emergency Department Sample (NEDS) were queried. ICD-10 and CPT codes identified homelessness, injury regions, depths, total body surface area (TBSA %), and treatment plans. Demographics, comorbidities, and charges were analyzed. Discharge weights generated national estimates. Statistical analysis included univariate testing and multivariate modeling.

RESULTS: Of 316,344 weighted ED visits meeting criteria, 1919 (0.6%) were homeless. Homeless encounters were older (mean age 44.83 vs. 32.39 years), male-predominant (71% vs. 52%), and had more comorbidities, and were more often White or Black race (p < 0.001). They more commonly presented to EDs in the West and were covered by Medicaid (51% vs. 33%) (p < 0.001). 12% and 5% of homeless burn injuries were related to self-harm and assault, respectively (p < 0.001). Homeless encounters experienced more third-degree burns (13% vs. 4%; p < 0.001), though TBSA % deciles were not significantly different (34% vs. 33% had TBSA % of ten or lower; p = 0.516). Homeless encounters were more often admitted (49% vs. 7%; p < 0.001), and homelessness increased odds of admission (OR 4.779; p < 0.001). Odds of transfer were significantly lower (OR 0.405; p = 0.021).

CONCLUSION: Homeless burn ED encounters were more likely due to assault and self-inflicted injuries, and more severe. ED practitioners should be aware of these patients’ unique presentation and triage to burn centers accordingly.
