ABSTRACT

BACKGROUND: Cancer treatment-induced bone loss (CTIBL) is the most common adverse event experienced by patients affected by breast cancer (BC) patients, without bone metastases. Bone modifying agents (BMAs) therapy is prescribed for the prevention of CTIBL, but it exposes patients to the risk of MRONJ.

METHODS: This multicentre hospital-based retrospective study included consecutive non-metastatic BC patients affected by MRONJ related to exposure to low-dose BMAs for CTIBL prevention. Patients’ data were retrospectively collected from the clinical charts of seven recruiting Italian centres.

RESULTS: MRONJ lesions were found in fifteen females (mean age 67.5 years), mainly in the mandible (73.3%). The mean duration of BMAs therapy at MRONJ presentation was 34.9 months. The more frequent BMAs was denosumab (53.3%). Ten patients (66.7%) showed the following local risk factors associated to MRONJ development: periodontal disease (PD) in three cases (20%) and the remaining six (40%) have undergone PD-related tooth extractions. One patient presented an implant presence-triggered MRONJ (6.7%). In five patients (33.3%) no local risk factors were observed.

CONCLUSIONS: This is the first case series that investigated BC patients under BMAs for CTIBL prevention suffering from MRONJ. These patients seem to have similar probabilities of developing MRONJ as osteo-metabolic ones. Breast cancer patients under BMAs for CTIBL prevention need a regular prevention program for MRONJ, since they may develop bone metastases and be treated with higher doses of BMAs, potentially leading to a high-risk of MRONJ.

ABSTRACT

BACKGROUND: The variability in the maxillary sinus anatomy makes dental implant planning challenging. One of the anatomical landmarks that could affect the decision for implant placement around the maxillary sinus is the sinus septa. This study aimed to retrospectively determine the prevalence, anatomical distribution, and morphology of the maxillary sinus septa.

MATERIALS AND METHODS: This study included 309 CBCT images that were analyzed to determine the prevalence, height, location, and orientation of the maxillary sinus septa. Descriptive statistics, Mann‒Whitney U tests, and Kruskal‒Wallis tests were used for data analysis.

RESULTS: A total of 618 maxillary sinuses were analyzed. Maxillary septa were present in 30% (n = 188) of the sinuses and in approximately 45% of the analyzed images. The mean height of the septa was 5.09 mm. The presence of bilateral septa was evident in 49 subjects (35.25%). Female subjects were significantly more likely to have only one septum (n = 67, 53.6%, p < 0.05).

CONCLUSION: The presence of septa is very common, found in one-third to approximately half of the evaluated cases, which warrants careful examination before any surgical interventions to avoid possible complications.

ABSTRACT

BACKGROUND: Opportunistic infections are a ubiquitous complication in human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) patients. Cryptosporidium spp., Giardia duodenalis, and Enterocytozoon bieneusi are common opportunistic intestinal pathogens in humans. In China, despite the number of HIV/AIDS patients being extremely large, only a few studies have investigated opportunistic infections caused by intestinal pathogens in this patient population. The aims of this study were to elucidate the occurrence and genetic characteristics of Cryptosporidium spp., G. duodenalis, and E. bieneusi in HIV/AIDS patients.

METHODS: We collected fecal specimens from 155 HIV/AIDS patients (one from each patient). All of the specimens were examined for the presence of the pathogens by genotyping using polymerase chain reaction and sequencing of the small subunit ribosomal RNA gene for Cryptosporidium spp.; the triosephosphate isomerase, β-giardin and glutamate dehydrogenase genes for G. duodenalis; and the internal transcribed spacer region of the rRNA gene for E. bieneusi. The Cryptosporidium-positive specimens were further subtyped by polymerase chain reacion and sequencing of the 60-kDa glycoprotein gene.

RESULTS: Six (3.9%), three (1.9%), and eight (5.2%) HIV/AIDS patients were positive for Cryptosporidium spp., G. duodenalis, and E. bieneusi, respectively. No statistical differences were observed in occurrence rate between the groups by gender, clinical symptom (diarrhea), and CD4⁺ cell count. Four Cryptosporidium species were identified: Cryptosporidium hominis (n = 2), Cryptosporidium parvum (n = 1), Cryptosporidium meleagridis (n = 1), and Cryptosporidium andersoni (n = 2). Furthermore, two C. hominis subtypes (IeA12G3T3 and IaA28R4) were detected. Three G. duodenalis-positive specimens were successfully amplified and sequenced at the triosephosphate isomerase and β-giardin loci, which led to the identification of assemblages C and B, respectively. Seven genotypes (D, Type IV, EbpC, Peru11, EbpD, A, and I) were identified in E. bieneusi-positive specimens.

CONCLUSIONS: Our findings should increase awareness of AIDS-related opportunistic intestinal pathogens, and indicate the need for routine examination in clinical practice for the detection of Cryptosporidium spp., G. duodenalis, and E. bieneusi. Homology analyses of the three intestinal pathogens at the nucleotide and/or amino acid levels indicated their zoonotic potential.

ABSTRACT

BACKGROUND: This analysis addresses the characteristics of two emergency department (ED) patient populations defined by three model diseases (hip fractures, respiratory, and cardiac symptoms) making use of survey (primary) and routine (secondary) data from hospital information systems (HIS). Our aims were to identify potential systematic inconsistencies between both data samples and implications of their use for future ED-based health services research.

METHODS: The research network EMANET prospectively collected primary data (n=1442) from 2017-2019 and routine data from 2016 (n=9329) of eight EDs in a major German city. Patient populations were characterized using socio-structural (age, gender) and health- and care-related variables (triage, transport to ED, case and discharge type, multi-morbidity). Statistical comparisons between descriptive results of primary and secondary data samples for each variable were conducted using binomial test, chi-square goodness-of-fit test, or one-sample t-test according to scale level.

RESULTS: Differences in distributions of patient characteristics were found in nearly all variables in all three disease populations, especially with regard to transport to ED, discharge type and prevalence of multi-morbidity. Recruitment conditions (e.g., patient non-response), project-specific inclusion criteria (e.g., age and case type restrictions) as well as documentation routines and practices of data production (e.g., coding of diagnoses) affected the composition of primary patient samples. Time restrictions of recruitment procedures did not generate meaningful differences regarding the distribution of characteristics in primary and secondary data samples.

CONCLUSIONS: Primary and secondary data types maintain their advantages and shortcomings in the context of emergency medicine health services research. However, differences in the distribution of selected variables are rather small. The identification and classification of these effects for data interpretation as well as the establishment of monitoring systems in the data collection process are pivotal.

ABSTRACT

BACKGROUND: An increased leukocyte count is a sign of inflammation and has been demonstrated to be a predisposing factor and complication of atrial fibrillation. Similarly, albumin, the major protein in the serum, is also considered an acute phase reactant protein that has osmotic and anti-inflammatory properties, and a low albumin level is a known factor associated with severity in many pathologies, including atrial fibrillation. The neutrophil percentage-to-albumin ratio (NPAR) and other emerging leukocyte counts/albumin ratios have been reliable systemic inflammation-based predictors of mortality and complications in various diseases, but they have not yet been used with atrial fibrillation. This study’s aim was to explore whether the leukocyte to albumin ratio could also serve as a useful index in estimating atrial fibrillation severity, including the severity of atrial fibrillation secondary to stroke, to provide a new and more objective tool than the conventional and medical history-based CHA2DS2-VASc score.

MATERIALS AND METHODS: Data were retrospectively collected from the Wuhan University Zhongnan Hospital database from January 1st to December 31st, 2021. The patients were classified into 2 groups: Group 1-low severity and Group 2- moderate to high severity, and diverse statistical analyses were conducted to evaluate the relationship between the leukocyte-to-albumin ratio and AF severity.

RESULTS: Only 2329 test subjects met the inclusion criteria. We had 727 test subjects (381 males and 346 females) categorized into the low severity cohort and 1601 test subjects (932 males and 670 females) in the moderate to high severity group. The difference in mean age between the two groups was significant (95% CI [-2.682 to -0.154] p = 0.028), and the difference in the LAR mean rank between the two groups was significant (p = 0.00). The Chi-square test of association yielded the following results: the relationship between the LAR level and category of severity was statistically significant (p = 0.00), and the Mantel‒Haenszel statistic association odds ratio was OR = 0.657. 95% CI OR [0.549-0.787] p = 0.000. The association between sex and atrial fibrillation severity also reached statistical significance. However, sex and LAR were found to be independent factors in atrial fibrillation (Chi-square p value = 0.564).

CONCLUSION: It has been demonstrated throughout this investigation that the leukocyte to albumin ratio could provide key clues in clinical practice and contribute to thromboembolism risk assessment in the setting of atrial fibrillation.

ABSTRACT

BACKGROUND: Feeding practices in the first two years of life have a direct impact on nutritional status and adiposity. The purpose of this study was to identify the differences in feeding practices during the first two years of life by sex and type of feeding in the first semester of postnatal life and their relationships with adiposity in toddlers.

METHODS: An analytical cross-sectional study that included 150 toddlers aged 12 to 24 months who were healthy, full-term, and had adequate weight for their gestational ages, was conducted at the New Civil Hospital and at a private practice in Guadalajara. Body compositions were obtained by bioelectrical impedance (BIA) measurements, and a modified questionnaire was used. Then, the parents completed two 24-h dietary recalls. In addition to the descriptive statistics, ANOVA, Kruskal-Wallis and Mann-Whitney U tests were used in the contrast analysis of the quantitative variables. To analyze the qualitative variables, we used X² tests. Afterward, linear regression tests were conducted to identify the relationships between adiposity and feeding practices during the first two years.

RESULTS: There were direct relationships between adiposity and duration of full breastfeeding (r = 0.610, p = 0.021), age of introduction of ultra-processed products (r = 0.311, p = 0.011), sugar (r = 0.186; p = 0.024) and age at which eggs were introduced (r = -0.202; p = 0.016).

CONCLUSIONS: Adiposity was related to feeding practices in the first two years of life in toddlers.

ABSTRACT

BACKGROUND: Teledentistry has demonstrated to expedite oral health consultations, diagnosis, and treatment planning while mitigating COVID-19 transmission risk in dental offices. However, the use of teledentistry by clinicians remains suboptimal. Therefore, this study aimed to determine the perceptions and practices of teledentistry among dentists during the COVID-19 pandemic in Ontario, Canada, and identify associated factors.

METHODS: A cross-sectional study using an online 39 item survey was conducted among Ontario dentists in December 2021. The questionnaire inquired about socio-demographic attributes, as well as perceptions of teledentistry use during the pandemic, and its future application. Descriptive statistics including frequency distribution of categorical variables and univariate analysis of continuous variables were conducted. Chi-square test was used determine the associations between professionals’ attributes such as age, gender, years of practice, and location of practice, and respondents use of teledentistry. SPSS Version 28.0 was used for statistical analysis.

RESULTS: Overall, 456 dentists completed the survey. The majority were general dentists (91%), worked in private practices (94%), were between 55 and 64 years old (33%), and had over 16 years of professional experience (72%). Approximately 49.3% reported using teledentistry; 13% started before the pandemic, and 36% during the pandemic. The most common reason for non-utilization was a lack of interest (54%). Respondents identified patient triage, consultation, and patient education as the three most important uses of teledentistry. Female dentists (p < 0.05), dentist working in private practice (p < 0.05), and those who worked in a single dental office (p < 0.05) adopted teledentistry more during the pandemic. Respondents who accessed more resources were more likely to report greater utilization of teledentistry, while those who reported being unconformable with teledentistry (p < 0.05) reported less utilization. Additionally, participants who reported feeling comfortable discussing teledentistry with others (p < 0.05), were more inclined to use it in the future.

CONCLUSIONS: Participants expressed mixed perceptions toward teledentistry with more than half indicating it is reliable for patient triaging and patient follow-ups. Despite the increased utilization during the COVID-19 pandemic, participants’ lack of interest in teledentistry emerged as a barrier to its use. More education and knowledge dissemination about teledentistry’s areas of application and technical aspects of use can increase interest in this tool, which may lead to a greater uptake by dental professionals.

ABSTRACT

BACKGROUND: Despite efforts to make maternal health care services available in rural Ethiopia, utilisation status remains low. Therefore, this study aimed to assess maternal health care services’ status and determinants in rural Ethiopia.

METHODS: The study used quasi-experimental pre- and post-comparison baseline data. A pretested, semi-structured, interviewer-administered questionnaire was used to collect data. A multilevel, mixed-effects logistic regression was used to identify individual and communal level factors associated with utilisation of antenatal care (ANC), skilled birth attendance (SBA), and postnatal care (PNC). The adjusted odds ratio (AOR) and corresponding 95% confidence intervals (CI) were estimated with a p-value of less than 0.05, indicating statistical significance.

RESULTS: Seven hundred and twenty-seven pregnant women participated, with a response rate of 99.3%. Four hundred and sixty-one (63.4%) of the women visited ANC services, while 46.5% (CI: 42-50%) of births were attended by SBA, and 33.4% (CI: 30-36%) had received PNC. Women who reported that their pregnancy was planned (aOR = 3.9; 95% CI: 1.8-8.3) and were aware of pregnancy danger signs (aOR = 6.8; 95% CI: 3.8-12) had a higher likelihood of attending ANC services. Among the cluster-level factors, women who lived in lowlands (aOR = 4.1; 95% CI: 1.1-14) and had easy access to transportation (aOR = 1.9; 95% CI: 1.1-3.7) had higher odds of visiting ANC services. Moreover, women who were employed (aOR = 3.1; 95% CI: 1.3-7.3) and attended ANC (aOR = 3.3; 95% CI: 1.8-5.9) were more likely to have SBA at delivery. The likelihood of being attended by SBA during delivery was positively correlated with shorter travel distances (aOR = 2.9; 95% CI: 1.4-5.8) and ease of access to transportation (aOR = 10; 95% CI: 3.6-29) to the closest healthcare facilities. Being a midland resident (aOR = 4.7; 95% CI: 1.7-13) and having SBA during delivery (aOR = 2.1; 95% CI: 1.2-3.50) increased the likelihood of attending PNC service.

CONCLUSIONS: Overall, maternal health service utilisation is low in the study area compared with the recommended standards. Women’s educational status, awareness of danger signs, and pregnancy planning from individual-level factors and being a lowland resident, short travel distance to health facilities from the cluster-level factors play a crucial role in utilising maternal health care services. Working on women’s empowerment, promotion of contraceptive methods to avoid unintended pregnancy, and improving access to health care services, particularly in highland areas, are recommended to improve maternal health service utilisation.

ABSTRACT

BACKGROUND: Tofacitinib is an oral small molecule Janus kinase inhibitor for the treatment of ulcerative colitis.

AIM: To report efficacy and infection rates in patients receiving tofacitinib induction treatment, by baseline corticosteroid status.

METHODS: We evaluated efficacy and safety data from OCTAVE Induction 1&2 in patients with moderately-to-severely active ulcerative colitis who received tofacitinib 10 mg twice daily or placebo for 8 weeks, based on induction baseline oral corticosteroid use (Corticosteroid-Yes/No) and dose (< 20/ ≥ 20 mg/day). Infections of interest included serious infections, herpes zoster (HZ), and adjudicated opportunistic infections (OIs).

RESULTS: At OCTAVE Induction 1&2 baseline, 478/1092 (43.8%) patients were receiving corticosteroids. Tofacitinib demonstrated significant induction efficacy versus placebo for both Corticosteroid-Yes and Corticosteroid-No. With adjustment for prior tumor necrosis factor inhibitor and immunosuppressant failure, there were no statistically significant differences in remission and clinical response rates for Corticosteroid-Yes versus Corticosteroid-No. Among tofacitinib-treated patients, HZ and OIs occurred more frequently in Corticosteroid-Yes versus Corticosteroid-No, regardless of dose (< 20 mg vs. ≥ 20 mg). Infection incidence rates (regardless of severity/seriousness) during tofacitinib induction were generally similar regardless of baseline corticosteroid use. The proportion of tofacitinib-treated patients with HZ was 0.2% for Corticosteroid-No versus 1.1% for Corticosteroid-Yes < 20 mg and 1.0% for Corticosteroid-Yes ≥ 20 mg. Two out of three patients had HZ OIs.

CONCLUSIONS: Tofacitinib induction efficacy (clinical response and remission) was similar in baseline corticosteroid subgroups. Infections of interest were rare; HZ and OIs occurred more frequently among those receiving tofacitinib and corticosteroids versus those receiving tofacitinib without corticosteroids.

ABSTRACT

BACKGROUND: Little is known on the impact of maternal age (MA) on very low birth weight (VLBW) infants’ outcomes. We tested the hypothesis that at both ends of MA there are increased adverse neonatal outcomes in VLBW infants.

METHODS: We used the Israel National Neonatal Network VLBW (≤1500 g) database. Maternal age was stratified as: <20, 20-24, 25-34 (reference group), 35-39 and ≥40 years. Statistical analyses were univariate and multivariable logistic regression analysis.

RESULTS: After adjustment, the infant outcomes of older mothers were similar to those of the reference group for mortality, RDS, severe ROP, NEC and sepsis. Mothers < 20 and 20-24 years old had higher odds of IVH grades 3-4 (OR 1.45, 95% CI 1.09-1.93 and OR 1.26, 95% CI 1.10-1.45, respectively), and BPD (OR 1.55, 95% CI 1.13-2.13 and OR 1.40, 95% CI 1.22-1.62, respectively). There were higher odds for PVL in infants of <20 year-old mothers (OR 1.83, 95% CI 1.26-2.65) and in infants of 35-39 year-old mothers (OR 1.38, 95% CI 1.12-1.69). Poor composite outcomes were significantly higher in the youngest maternal age categories (<20-year-old mothers (OR 1.63, 95% CI 1.28-2.08), and 20-24-year-old (OR 1.28, 95% CI 1.15-1.43).

CONCLUSIONS: Neonatal outcomes differ in relation to maternal age among very low birth weight newborns, with adverse outcomes more predominant in infants of younger mothers.
