Prescription trends of disease-modifying treatments for multiple sclerosis in Iran over the past 30 years

Mult Scler Relat Disord. 2022 Mar 27;61:103777. doi: 10.1016/j.msard.2022.103777. Online ahead of print.

ABSTRACT

BACKGROUND: Iran, as a middle income country, is one of the places with high and rising prevalence of multiple sclerosis (MS). Regarding the substantial economic burden, reviewing the trend in prescribed disease modifying treatments (DMTs) could be of help. Here we studied the DMT information of nearly 14000 MS cases and its trends change for 30 years to improve health services to patients.

METHODS: The population base of this descriptive-analytical (cross-sectional) study consisted of all MS patients in the nationwide MS registry of Iran (NMSRI), up to August 1, 2021. Registrars from 15 provinces, 24 cities, 13 hospitals,8 MS associations, 16 private offices, and 7 clinics had entered the data.

RESULTS: Overall, 14316 cases were enrolled. The majority (76.1%) were female. The youngest and eldest patients were 5 and 78 years old, respectively. Diagnosis delay was under one year in most cases (median: 0, IQR: 0 – 1). Most (61.4%) had RRMS. Generally, platform injectables (IFN beta, glatiramer acetate) were the most used DMTs until 2010. It seems that introduction of newer agents (antiCD20s and oral DMTs) resulted in a decrease in the use of former drugs since around 2015. Some unusual practices are prominent such as using not approved DMTs for PPMS over the years, or administering high efficacy drugs like natalizumab for CIS. The results indicate the remaining popularity of first line injectable DMTs in female and pediatric patients.

DISCUSSION: Mean age (SD) at onset in our study (29 ± 8.8) is near the statistics in Asia and Oceania (28 ± 0.7). Concerns about COVID-19 had a noticeable impact on administering high efficacy drugs like rituximab and fingolimod. However, in male patients this approach has not been the case. It may be related to more aggressive disease course in this group. The other possible explanation could be planning for pregnancy in female cases. The popularity of platform injectable drugs in pediatric MS may be related to its favorable safety profile over the years. Another point in this group, is the superiority of rituximab over other highly efficient medications.

Incidence patterns of childhood non-Wilms renal tumors: Comparing data of the Nationwide Registry of Childhood Hematological Malignancies and Solid Tumors (NARECHEM-ST), Greece, and the Surveillance, Epidemiology, and End Results Program (SEER), USA

Cancer Epidemiol. 2022 Apr 4;78:102153. doi: 10.1016/j.canep.2022.102153. Online ahead of print.

ABSTRACT

BACKGROUND: We used, for the first time, data registered in the Nationwide Registry for Childhood Hematological Malignancies and Solid Tumors (NARECHEM-ST)-Greece to estimate incidence/time trends of the rare childhood (0-14 years) non-Wilms tumors (non-WT), and compared the results of malignant non-WT to those from the Surveillance, Epidemiology, and End Results Program (SEER)-USA.

METHODS: Fifty-five cases (n = 33 malignant-only) were extracted from NARECHEM-ST (2001-2020) and 332 malignant cases from SEER (1990-2017). To allow between-country comparisons, age-standardized incidence rates (AIR) of malignant-only non-WT were calculated, and temporal trends were evaluated using Poisson and joinpoint regressions.

RESULTS: In NARECHEM-ST, malignant and non-malignant non-WT accounted for 22.6% of all renal tumors. Among malignant tumors, the AIR was 1.0/106 children in Greece, similar to that calculated for SEER, USA (AIR=0.9/106). The proportion of infant malignant and non-malignant non-WT was 27% (20% before 6 months) in NARECHEM-ST. Most common non-WT in Greece were congenital mesoblastic nephromas (CMN) diagnosed mainly in infancy (CIR=7.2/106). The proportion of infant malignant non-WT was 20% in SEER (AIRinfancy=2.5/106), mainly attributed to rhabdoid tumors (CIR=1.6/106). The male-to-female (M:F) ratio of malignant non-WT was 0.9 in NARECHEM-ST vs. 1.2 in SEER, whereas boys outnumbered girls with clear cell sarcoma in NARECHEM-ST (M:F=4.0). Lastly, significantly increasing trends in incidence rates were noted in NARECHEM-ST [+ 6.8%, 95% confidence intervals (CI): 0.5, 13.3] and in SEER (+7.3%, 95%CI: 5.6, 9.0).

CONCLUSIONS: Observed incidence, time trends and sociodemographic variations of non-WT may reflect differential registration practices and healthcare delivery patterns including differences regarding surveillance, coding and treatment practices.

Surgical Rib Fixation of Multiple Rib Fractures and Flail Chest: A Systematic Review and Meta-Analysis

J Surg Res. 2022 Apr 4;276:221-234. doi: 10.1016/j.jss.2022.02.055. Online ahead of print.

ABSTRACT

BACKGROUND: Multiple rib fractures and flail chest are common in trauma patients and may result in significant morbidity and mortality. While rib fractures have historically been treated conservatively, there is increasing interest in the benefits of surgical fixation. However, strong evidence that supports surgical rib fixation and identifies the most appropriate patients for its application is currently sparse.

METHODS: A systematic review and meta-analysis following PRISMA guidelines was performed to identify all peer-reviewed papers that examined surgical compared to conservative management of rib fractures. We undertook a subgroup analysis to determine the specific effects of rib fracture type, age, the timing of fixation and study design on outcomes. The primary outcomes were the length of hospital and ICU stay, and secondary outcomes included mechanical ventilation time, rates of pneumonia, and mortality.

RESULTS: Our search identified 45 papers in the systematic review, and 40 were included in the meta-analysis. There was a statistical benefit of surgical fixation compared to conservative management of rib fractures for length of ICU stay, mechanical ventilation, mortality, pneumonia, and tracheostomy. The subgroup analysis identified surgical fixation was most favorable for patients with flail chest and those who underwent surgical fixation within 72 h. Patients over 60 y had a statistical benefit of conservative management on length of hospital stay and mechanical ventilation.

CONCLUSIONS: Surgical fixation of flail and multiple rib fractures is associated with a reduction in morbidity and mortality outcomes compared to conservative management. However, careful selection of patients is required for the appropriate application of surgical rib fixation.

Pre-diagnosis lifestyle, health history and psychosocial factors associated with stage at breast cancer diagnosis – Potential targets to shift stage earlier

Cancer Epidemiol. 2022 Apr 4;78:102152. doi: 10.1016/j.canep.2022.102152. Online ahead of print.

ABSTRACT

BACKGROUND: Early detection of breast cancer improves survival, so identifying factors associated with stage at diagnosis may help formulate cancer prevention messages tailored for higher risk women. The goal of this study was to evaluate associations between multiple potential risk factors, including novel ones, measured before a breast cancer diagnosis and stage at diagnosis in women from Alberta, Canada.

METHODS: Women enrolled in Alberta’s Tomorrow Project completed health and lifestyle questionnaires on average 7 years before their breast cancer diagnosis. The association of previously identified and novel predictors with stage (I, II and III + IV) at diagnosis were simultaneously evaluated in partial proportional odds ordinal (PPO) regression models.

RESULTS: The 492 women in this study were predominantly diagnosed in Stage 1 (51.4%), had college or university education (75.4%), were married or had a partner (74.6%), had been pregnant (90.2%), had taken birth control pills for any reason (86.8%), and had an average body mass index of 26.6. Most had at least one mammogram (83%) with five mammograms the average number. Nearly all reported previously having a breast health examination from a medical practitioner (92.5%). Statistically significant factors identified in the PPO model included protective ones (older age at diagnosis, high household income, parity, smoking, spending time in the sun during high ultraviolet times, having a mammogram and high daily protein intake) and ones that increased risk of later stage at diagnosis (a comorbidity, current stressful situations and high daily caloric intake).

CONCLUSION: Shifting breast cancer stage at diagnosis downwards may potentially be achieved through cancer prevention programs that target higher risk groups such as women with co-morbidities, non-smokers and younger women who may be eligible for breast cancer screening.

Characterization of sedation and anesthesia complications in patients with alternating hemiplegia of childhood

Eur J Paediatr Neurol. 2022 Mar 29;38:47-52. doi: 10.1016/j.ejpn.2022.03.007. Online ahead of print.

ABSTRACT

BACKGROUND: Alternating hemiplegia of childhood (AHC) pathophysiology suggests predisposition to sedation and anesthesia complications.

GOALS: Hypotheses: 1) AHC patients experience high rates of sedation-anesthesia complications. 2) ATP1A3 mutation genotype positivity, age, and AHC severity correlate with more severe complications. 3) Prior short QTc correlates with cardiac rhythm complications.

METHODS: Analysis of 34 consecutive AHC patients who underwent sedation or anesthesia. Classification of complications: mild (not requiring intervention), moderate (intervention), severe (intervention, risk for permanent injury or potential life-threatening emergency).

STATISTICS: Fisher Exact test, Spearman correlations.

RESULTS: These patients underwent 129 procedures (3.79 ± 2.75 procedures/patient). Twelve (35%) experienced complications during at least one procedure. Fourteen/129 procedures (11%) manifested one or more complications (2.3% mild, 7% moderate, 1.6% severe). Of the total 20 observed complications, six (33.3%) were severe: apneas (2), seizures (2), bradycardia (1), ventricular fibrillation that responded to resuscitation (1). Moderate complications: non-life-threatening bradycardias, apneas, AHC spells or seizures. Complications occurred during sedation or anesthesia and during procedures or recovery periods. Patients with disease-associated ATP1A3 variants were more likely to have moderate or severe complications. There was no correlation between complications and age or AHC severity. Presence of prior short QTc correlated with cardiac rhythm complications. After this series was analyzed, another patient had severe recurrent laryngeal dystonia requiring tracheostomy following anesthesia with intubation.

CONCLUSIONS: During sedation or anesthesia, AHC patients, particularly those with ATP1A3 variants and prior short QTc, are at risk for complications consistent with AHC pathophysiology. Increased awareness is warranted during planning, performance, and recovery from such procedures.

Determining reference data for overnight oximetry in neonates: A pilot study

Early Hum Dev. 2022 Apr 1;168:105571. doi: 10.1016/j.earlhumdev.2022.105571. Online ahead of print.

ABSTRACT

OBJECTIVE: To determine the variability of overnight oximetry parameters in a group of normal, healthy term infants; to enable the calculation of the number of subjects required to produce reliable reference ranges for neonatal overnight oximetry.

METHODS: A convenience sample of normal, healthy term neonates was recruited. Each had overnight oximetry using the Masimo SET Radical oximeter (data downloaded using Profox software). The report included the number of oxygen desaturation events (an absolute decrease in SpO2 of 4 or more), and the duration of oxygen saturations <90%.

RESULTS: 21 babies were recruited with data available from 19. 32% were female; 68% born by vaginal delivery; 37% fully breast feeding, 53% bottle and 11% by a combination of both. The mean (SD) GA was 39.2 (0.79) weeks, the mean (SD) BW was 3477 (240) grams. The median (IQR) post-natal age at the time the oximetry recording started was 31 (28-41) hours; four babies were <24 h old. All babies had some desaturation events ranging from 4 to 36 times per hour. On average babies spent 3.0% (SD 2.3) of the time with an SpO2 < 90% (range 0.12-7.94).

CONCLUSIONS: In a cohort of healthy term neonates, as assessed by overnight oximetry, the mean SpO2 was 97% (SD 1, range 95-99). All neonates had a number of oxygen desaturation events ranging from 4 to 36 per hour. The mean proportion of time spent with oxygen saturations below 90% was around 3%.

Surgical management of giant calcified thoracic disc herniation and the role of neuromonitoring. The outcome of large mono centric series

J Clin Neurosci. 2022 Apr 4;100:37-45. doi: 10.1016/j.jocn.2022.03.046. Online ahead of print.

ABSTRACT

PURPOSE: Giant thoracic disc herniations (GTDH) are considered a subgroup of TDHs with worse functional outcomes, a high calcification rate, and a considerable risk of complications. We aimed to determine whether there is a relationship between the extent of calcification of GTDH and outcomes concerning the risk of complications, the surgical technique, and changes in neuromonitoring signals.

METHODS: We present a retrospective analysis of 76 patients undergoing surgery for calcific GTDH. We introduced and defined a radiological definition of the calcified disc into”fully calcified” and “partially calcified.” We performed a statistical analysis between clinical and radiological variables, type of surgical procedure, the extent of excision, neuro-monitoring signals, and outcome, comparing a group of 58 “fully-calcified TDH” patients and 18 “partially-calcified TDH” patients.

RESULTS: Fully calcified TDHs, compared with partially calcified TDHs, do not have significant differences in outcome (worse outcome 4/58-6.9% versus 0/18, p = 0.25) and complications (10/58-17.24% versus 4/18-22.2%, p = 0.63); Fully calcified TDH is associated with a higher risk of alterations in neurophysiological potentials (14/58-24.1% versus 0/18, p = 0.02) and subtotal excision (18/58-31% versus 2/18-11%, p = 0.15), without significant differences between the approaches used.

CONCLUSION: Fully calcified TDH group has a similar outcome and complication rate as the partially calcified TDH group, but they are associated with higher intraoperative neuromonitoring signal changes. We introduced a new classificationsystem that guides the approach and helps tocounsel the patients.

Small bowel capsule endoscopy in obscure gastrointestinal bleeding: A matched cohort comparison of patients with normal vs surgically altered gastric anatomy

Clin Res Hepatol Gastroenterol. 2022 Apr 4:101921. doi: 10.1016/j.clinre.2022.101921. Online ahead of print.

ABSTRACT

BACKGROUND: Little is known about small bowel capsule endoscopy (SBCE) outcomes in patients with surgically altered anatomy.

AIMS: To assess the feasibility and diagnostic yield of orally ingested SBCE to investigate obscure gastrointestinal bleeding (OGIB) in patients with surgically altered gastric anatomy, compared to native gastric anatomy.

METHODS: 207 patients with OGIB were selected from an open, multicenter, retrospective cohort (SAGA study) and match-paired according to age, gender and bleeding type (overt/occult) to 207 control patients from a randomized controlled trial (PREPINTEST). Primary outcomes were the diagnostic yield (P1 or P2 findings), completion rate (CR), adverse events rate AER, and small bowel transit time (SBTT).

RESULTS: The diagnostic yield was not statistically different between groups (44.9% in SAGA vs 42.5% in control patients). Inflammatory/ulcerated lesions were significantly more frequent in patients with SAGA (43.0% vs 29.3%). The median SBTT was significantly longer in the SAGA group than in control patients (283 vs 206 minutes), with a significantly lower CR (82.6% vs 89.9%); Adverse events were scarce (0.5% vs 0.0%).

CONCLUSION: Patients with surgically altered gastric anatomy should benefit from SBCE investigation for OGIB as much as non-operated patients.

The development of ADAM10 endocytosis inhibitors for the treatment of Alzheimer’s disease

Mol Ther. 2022 Apr 4:S1525-0016(22)00227-1. doi: 10.1016/j.ymthe.2022.03.024. Online ahead of print.

ABSTRACT

The development of new therapeutic avenues that target the early stages of Alzheimer’s disease (AD) is urgently necessary. ADAM10 is a sheddase that is involved in dendritic spine shaping and limits the generation of amyloid-β. ADAM10 endocytosis increases in the hippocampus of AD patients, resulting in the decreased postsynaptic localization of the enzyme. To restore this altered pathway, we developed a cell-permeable peptide (PEP3) with a strong safety profile that is able to interfere with ADAM10 endocytosis, upregulating the postsynaptic localization and activity of ADAM10. After extensive validation, experiments in a relevant animal model clarified the optimal timing of the treatment window. PEP3 administration was effective for the rescue of cognitive defects in APP/PS1 mice only if administered at an early disease stage. Increased ADAM10 activity promoted synaptic plasticity, as revealed by changes in the molecular compositions of synapses and the spine morphology. Even though further studies are required to evaluate efficacy and safety issues of long-term administration of PEP3, these results provide preclinical evidence to support the therapeutic potential of PEP3 in AD.

The accuracy of portion size reporting on self-administered online 24-hour dietary recalls among women with low incomes

J Acad Nutr Diet. 2022 Apr 4:S2212-2672(22)00175-7. doi: 10.1016/j.jand.2022.03.018. Online ahead of print.

ABSTRACT

BACKGROUND: Accurately estimating portion sizes remains a challenge in dietary assessment. Digital images used in online 24-hour dietary recalls may be conducive to accuracy.

OBJECTIVE: The current analyses were conducted to examine the accuracy of portion size estimation by women with low incomes who completed 24-hour dietary recalls using the online Automated Self-Administered 24-hour Dietary Assessment Tool (ASA24) in the Food and Eating Assessment STudy (FEAST) II.

DESIGN: True dietary intake was observed for three meals on one day through a controlled feeding study conducted from May through July, 2016. The following day, participants completed an unannounced 24-hour dietary recall using ASA24, independently or with assistance in a small group setting.

PARTICIPANTS/SETTING: Participants included 302 women aged 18 to 82 years living in the Washington, DC area who met the income thresholds for the Supplemental Nutrition Assistance Program.

MAIN OUTCOME MEASURES: The accuracy of portion size estimation was assessed by comparing the weight truly consumed (observed) and the weight reported for pre-determined categories of foods and beverages.

STATISTICAL ANALYSES PERFORMED: The differences between observed and reported portions were examined and linear regression tested differences by recall condition. Analyses were conducted by condition and repeated with stratification by racial/ethnic identity, education, and body mass index.

RESULTS: On average across foods and beverages, reported portion sizes were 7.4 grams (95% CI, 4.3-10.5) and 6.4 grams (95% CI, 2.8-10.0) higher than observed portion sizes in the independent and assisted conditions, respectively. Portion sizes were overestimated for small pieces and shaped foods in both conditions, as well as for amorphous/soft foods in the assisted condition and underestimated for single unit foods in both conditions. Misestimation was fairly consistent by participants’ race/ethnicity, education, and body mass index, to varying magnitudes.

CONCLUSIONS: Women with low incomes overestimated the amounts of foods and beverages consumed across several categories using online 24-hour dietary recalls with digital images to support portion size estimation. Assistance with ASA24 had little impact on accuracy.
