Problematic substance use in depressed adolescents: Prevalence and clinical correlates

Background

Substance use among adolescents is common and associated with significant consequences, including depression. Adolescents can experience myriad problems related to early onset substance use and depression, making further understanding of this comorbidity necessary.

Method

Participants were a subset from a large-scale performance improvement project and consisted of adolescents aged 12-18 who screened positive for depression during their routine medical or psychiatric appointment and who then completed the substance use assessment Car, Relax, Alone, Forget, Friends, Trouble Version 2.1 (CRAFFT). Participants with problematic substance use had a CRAFFT score ≥2.

Results

A total of 621 participants were included in this study, and 105 (16.9%) reported problematic substance use. Compared with participants without problematic substance use, those with problematic use were more likely to have moderate to severe depression and anxiety, as well as significantly higher irritability, impulsivity, suicidal propensity, and suicidal thoughts scores. Controlling for age at screening, sex, race, and ethnicity, problematic substance use remained a significant predictor of depression severity, impulsivity, suicidal propensity, and suicidal thoughts.

Limitations

Participants were from a large, metropolitan area of the Southwest United States who must have screened positive for depression, so results may not generalize. Because all participants were underage, they may have been wary in responding to the substance use assessment accurately.

Conclusions

By using a large, diverse sample in a real-world clinical setting, findings strengthen the association between problematic substance use and depression and depression-associated symptoms among adolescents, highlighting the need for early detection and universal depression screening.

A case of fatal fulminant fat embolism syndrome saved by VA-ECMO in the acute phase of multiple trauma

Fat embolism syndrome (FES) is a rare complication of long bone fractures, with fulminant FES developing within 12 h of injury and often proving fatal (Shaikh, 2009 [1]). Here, we present a case of fulminant FES in a patient who developed sudden right heart failure after undergoing external fixation of a lower leg fracture and required veno-arterial extracorporeal membrane oxygenation (VA-ECMO). A 79-year-old woman injured in a traffic accident was transferred to our emergency department. Upon arrival, her level of consciousness deteriorated, and she developed circulatory failure. We promptly performed transcatheter arterial embolization for the pelvic fracture and external fixation of the tibiofibular fracture. Within four hours of the injury, she was admitted to our intensive care unit (ICU). Two hours after ICU admission, her hemodynamic status worsened, necessitating the administration of maximum catecholamine dose. Echocardiography revealed petechial hemorrhage of the palpebral conjunctiva and enlargement of the right ventricle. Despite maximal supportive care, the patient remained cardiovascularly unstable. Therefore, VA-ECMO was initiated to stabilize her hemodynamic status. Thereafter, her hemodynamics stabilized, and ECMO support was weaned off and removed on day 3. Subsequent magnetic resonance imaging revealed evidence of cerebral fat embolism. On day 9, she underwent open reduction of the left lower leg with internal fixation and was transferred to another hospital on day 29. This report documents the successful management of fulminant FES during the acute phase of multiple traumas. Clinicians should consider VA-ECMO when suspecting uncontrolled circulatory failure due to fulminant FES, even in the acute phase of multiple trauma.

Risk for fetal malformations and unfavorable neonatal outcomes in early-onset gestational diabetes mellitus

BACKGROUND

Early-onset gestational diabetes mellitus (GDM) is diagnosed before the 24th gestational week. Since early GDM is associated with first trimester hyperglycemia, many clinicians treat these women as having pre-GDM. However, whether early GDM increases the risk for unfavorable pregnancy outcomes and particularly for fetal malformations to a greater extent than late-onset GDM were not studied sufficiently. We aimed to examine the effect of early-onset GDM on unfavorable pregnancy outcomes.

METHODS

A retrospective cohort study of women with GDM delivering singletons during 2005-2018 was conducted. Women were divided into GDM diagnosed at the first (Trimester1; up to 13.6 weeks; N = 117), the second (Trimester2; up to 23.6 weeks; N = 126), and the third trimester (Trimester3; N = 2334). The primary outcomes were neonatal malformations and a composite of large-for-age newborns, hypoglycemia and hyperbilirubinemia treated with phototherapy. Comparisons were made between early- (Trimester1 + Trimester2-groups) and late-onset GDM (Trimester3-group), and between the three trimesters.

RESULTS

Fetal malformations were low and comparable between the trimester1, trimester2, trimester3 groups (2 (1.7%), 3 (2.4%), and 110 (4.7%), respectively). The composite neonatal complications was similar between the groups (68 (58%), 58 (46%), and 1087 (47%), respectively). In early-onset, the rates of neonatal hypoglycemia and shoulder dystocia were higher than in the late-onset GDM group (OR 95% CI 3.5 [2.0-6.1] and 10.3 [2.4-44.6], respectively). Macrosomia was higher in trimester1 compared with trimester2 and trimester3 cohorts (OR 95% CI 5.3 [1.7-16.9] and 2.8 [1.5-5.2], respectively).

CONCLUSIONS

The risk for fetal malformations was low and comparable between the first, second and third trimester GDM. Since the risks for macrosomia, shoulder dystocia, and neonatal hypoglycemia are higher in early-onset GDM, these women should undergo strict glycemic control, intensive monitoring, and careful neonatal evaluation.

Early Onset Intrahepatic Cholangiocarcinoma: Clinical Characteristics, Oncological Outcomes, and Genomic/Transcriptomic Features

INTRODUCTION

Data on clinical characteristics and disease-specific prognosis among patients with early onset intrahepatic cholangiocarcinoma (ICC) are currently limited.

METHODS

Patients undergoing hepatectomy for ICC between 2000 and 2020 were identified by using a multi-institutional database. The association of early (≤50 years) versus typical onset (>50 years) ICC with recurrence-free (RFS) and disease-specific survival (DSS) was assessed in the multi-institutional database and validated in an external cohort. The genomic and transcriptomic profiles of early versus late onset ICC were analyzed by using the Total Cancer Genome Atlas (TCGA) and Memorial Sloan Kettering Cancer Center databases.

RESULTS

Among 971 patients undergoing resection for ICC, 22.7% (n = 220) had early-onset ICC. Patients with early-onset ICC had worse 5-year RFS (24.1% vs. 29.7%, p < 0.05) and DSS (36.5% vs. 48.9%, p = 0.03) compared with patients with typical onset ICC despite having earlier T-stage tumors and lower rates of microvascular invasion. In the validation cohort, patients with early-onset ICC had worse 5-year RFS (7.4% vs. 20.5%, p = 0.002) compared with individuals with typical onset ICC. Using the TCGA cohort, 652 and 266 genes were found to be upregulated (including ATP8A2) and downregulated (including UTY and KDM5D) in early versus typical onset ICC, respectively. Genes frequently implicated as oncogenic drivers, including CDKN2A, IDH1, BRAF, and FGFR2 were infrequently mutated in the early-onset ICC patients.

CONCLUSIONS

Early-onset ICC has distinct clinical and genomic/transcriptomic features. Morphologic and clinicopathologic characteristics were unable to fully explain differences in outcomes among early versus typical onset ICC patients. The current study offers a preliminary landscape of the molecular features of early-onset ICC.

Early Onset Inherited Peripheral Neuropathies: The Experience of a Specialized Referral Center for Genetic Diagnosis Achievement

BACKGROUND

Charcot-Marie-Tooth disease (CMT) is a heterogeneous group of inherited peripheral neuropathies. Although the typical disease onset is reported in the second decade, earlier onsets are not uncommon. To date, few studies on pediatric populations have been conducted and the achievement of molecular diagnosis remains challenging.

METHODS

During the last 24 years we recruited 223 patients with early-onset hereditary peripheral neuropathies (EOHPN), negative for PMP22 duplication, 72 of them referred by a specialized pediatric hospital. Genetic testing for CMT-associated genes has been carried out with a range of different techniques.

RESULTS

Of the 223 EOHPN cases, 43% were classified as CMT1 (demyelinating), 49% as CMT2 (axonal), and 8% as CMTi (intermediate). Genetic diagnosis was reached in 51% of patients, but the diagnostic yield increased to 67% when focusing only on cases from the specialized pediatric neuromuscular centers. Excluding PMP22 rearrangements, no significant difference in diagnostic rate between demyelinating and axonal forms was identified. De novo mutations account for 38% of cases.

CONCLUSIONS

This study describes an exhaustive picture of EOHPN in an Italian referral genetic center and analyzes the molecular diagnostic rate of a heterogeneous cohort compared with one referred by a specialized pediatric center. Our data identify MPZ, MFN2, GDAP1, and SH3TC2 genes as the most frequent players in EOHPN. Our study underlines the relevance of a specific neurological pediatric expertise to address the genetic testing and highlights its importance to clarify possible unexpected results when neuropathy is only a secondary clinical sign of a more complex phenotype.

Early-onset obsessive-compulsive disorder: Sociodemographic and clinical characterization of a large outpatient cohort

INTRODUCTION

Obsessive-compulsive disorder (OCD) is a prevalent and disabling condition characterized by a wide variety of phenotypic expressions. Several studies have reinforced the hypothesis of OCD heterogeneity by proposing subtypes based on predominant symptomatology, course, and comorbidities. Early-onset OCD (EO) could be considered a neurodevelopmental subtype of OCD, with evidence of distinct neurocircuits supporting disease progression. To deepen the heterogeneous nature of the disorder, we analyzed sociodemographic and clinical differences between the EO and late-onset (LO) subtypes in a large outpatient cohort.

METHODS

Two hundred and eighty-four patients diagnosed with OCD were consecutively recruited from the OCD Tertiary Clinic at Luigi Sacco University Hospital in Milan. Sociodemographic and clinical variables were analyzed for the entire sample and compared between the two subgroups (EO, age <18 years [n = 117,41.2 %]; LO: late-onset, age ≥18 years [n = 167, 58.8 %]).

RESULTS

The EO group showed a higher frequency of male gender (65 % vs 42.5 %, p < .001), and a higher prevalence of Tic and Tourette disorders (9.4 % vs 0 %, p < .001) compared to the LO group. Additionally, in the EO subgroup, a longer duration of untreated illness was observed (9.01 ± 9.88 vs 4.81 ± 7.12; p < .001), along with a lower presence of insight (13.8 % vs. 7.5 %, p < .05).

CONCLUSIONS

The early-onset OCD subtype highlights a more severe clinical profile compared to the LO group. Exploring distinct manifestations and developmental trajectories of OCD can contribute to a better definition of homogeneous subtypes, useful for defining targeted therapeutic strategies for treatment.

Cancer incidence trends in New York State and associations with common population-level exposures 2010-2018: an ecological study

The impact of common environmental exposures in combinations with socioeconomic and lifestyle factors on cancer development, particularly for young adults, remains understudied. Here, we leveraged environmental and cancer incidence data collected in New York State at the county level to examine the association between 31 exposures and 10 common cancers (i.e., lung and bronchus, thyroid, colorectal, kidney and renal pelvis, melanoma, non-Hodgkin lymphoma, and leukemia for both sexes; corpus uteri and female breast cancer; prostate cancer), for three age groups (25-49, 50-69, and 70-84 year-olds). For each cancer, we stratified by age group and sex, and applied regression models to examine the associations with multiple exposures simultaneously. The models included 642,013 incident cancer cases during 2010-2018 and found risk factors consistent with previous reports (e.g., smoking and physical inactivity). Models also found positive associations between ambient air pollutants (ozone and PM2.5) and prostate cancer, female breast cancer, and melanoma of the skin across multiple population strata. Additionally, the models were able to better explain the variation in cancer incidence data among 25-49 year-olds than the two older age groups. These findings support the impact of common environmental exposures on cancer development, particularly for younger age groups.

Retrospective genetic testing (Traceback) in women with early-onset breast cancer after revised national guidelines: a clinical implementation study

PURPOSE

This study focused on identifying a hereditary predisposition in women previously diagnosed with early-onset breast cancer through a retrospective outreach activity (Traceback). The objectives were to evaluate the possible clinical implementation of a simplified Traceback strategy and to identify carriers of pathogenic variants among previously untested women.

METHODS

Three hundred and fifteen Traceback-eligible women diagnosed with breast cancer at 36-40 years in Southern Sweden between 2000 and 2019 were identified and offered an analysis of the genes ATM, BARD1, BRCA1, BRCA2, CHEK2, PALB2, RAD51C, and RAD51D through a standardized letter. Women who chose to participate were asked about their experiences through a questionnaire. The workload for the study personnel was measured and recorded.

RESULTS

One hundred and seventy-six women underwent genetic testing and pathogenic variants were identified in 9.7%: ATM (n = 6), BARD1 (n = 1), BRCA1 (n = 3), CHEK2 (n = 5), and PALB2 (n = 2). Women with normal test results were informed through a standardized letter. Carriers of pathogenic variants were contacted by telephone and offered in-person genetic counseling. One hundred and thirty-four women returned the subsequent questionnaire. Most study participants were satisfied with both written pre- and post-test information and many expressed their gratitude. The extra workload as compared to routine clinical genetic counseling was modest (8 min per patient).

CONCLUSION

The insights from the participants' perspectives and sentiments throughout the process support the notion that the Traceback procedure is a safe and an appreciated complement to routine genetic counseling. The genetic yield of almost 10% also suggests that the associated extra workload for genetic counselors could be viewed as acceptable in clinical implementation scenarios.

Early-versus late-onset sepsis in neonates - time to shift the paradigm?

BACKGROUND

Neonatal sepsis is traditionally classified as early-onset sepsis (EOS) and late-onset sepsis (LOS) disease categories. This paradigm was based on observed epidemiological data from high income settings. However, increasing availability of microbiology results from diverse settings challenges these assumptions, necessitating re-examination of neonatal sepsis classifications.

OBJECTIVES

To review the literature describing the aetiology of EOS and LOS in hospitalized neonates with stratification of pathogen spectrum by low- (LIC), middle- (MIC) and high-income (HIC) country settings, to critically re-examine the continued appropriateness of the 'EOS vs. LOS' sepsis paradigm in all settings.

SOURCES

PubMed was searched for peer-reviewed English full-text articles published from inception up until 8 August 2022.

CONTENT

Studies often report on either EOS or LOS, rather than both. We identified only 49 original articles reporting on pathogen distribution of both EOS and LOS in the same hospital setting. Clear differences in sepsis aetiology were shown between LIC, MIC and HIC settings, with increasing importance of Klebsiella pneumoniae and decreasing importance of Group B Streptococcus in the first 72 hours of life in LIC and MIC.

IMPLICATIONS

The concept of 'EOS vs. LOS' may be less useful for predicting the pathogen spectrum of neonatal sepsis in LIC and MIC, but the paradigm has shaped reporting of neonatal sepsis, and our understanding. Future neonatal sepsis reporting should utilize strengthening the reporting of observational studies in epidemiology for newborn infection (STROBE-NI) reporting guidelines and clearly describe timing of infection by day, and variation in pathogen spectrum across the neonatal period. Data identified in this review challenge the generalizability of the prevailing EOS/LOS paradigm in LIC and MIC.

Clinical and radiologic differences between early onset, late onset, and very late onset adult multiple sclerosis

BACKGROUND

Previous studies suggested possible differences in clinical and radiologic characteristics between early-onset multiple sclerosis (EOMS) and late-onset MS (LOMS). However, differences between LOMS and very late onset MS (VLOMS) are largely unknown.

METHODS

We performed a retrospective review of medical records of patients diagnosed with MS between 8/1/2017 and 3/1/2022 at the comprehensive MS center of the Froedtert and Medical College of Wisconsin. We included adult patients with MS diagnosis who were 60 years or older - VLOMS, 50-59 years old at diagnosis - LOMS, or were 18-30 years old at diagnosis - EOMS and had complete imaging and clinical records. Clinical presentation and location of demyelinating lesions at the onset of diagnosis were extracted and compared using the chi-square test, p<0.05.

RESULTS

A total of 246 newly diagnosed patients were identified. Of which 54 were EOMS, 29 were LOMS, and 35 were VLOMS. The sex ratio was not different between groups. EOMS had a higher percentage of patients who self-identified as black, while LOMS had a higher percentage of patients who self-identified as white. LOMS and VLOMS showed significant differences in the presence of tremors and lesion distribution at the onset. Older onset patients were more likely to present with motor symptoms, sphincter dysfunction, fatigue, and tremor. EOMS was more likely to present with cerebellum and occipital lobe lesions, and lesions were more likely to show contrast enhancement on MRI at diagnosis.

CONCLUSION

Our findings revealed novel clinical and imaging characteristics differences between VLOMS and LOMS. The current classification of LOMS may benefit from revision to better align with chronological age classification for old age >60 instead of the current standard in the literature of >50 years.

Association of clinical characteristics and recurrence of conventional colorectal adenomas with patient age: a single-center study

OBJECTIVES

We performed a clinical study comparing early-onset and late-onset conventional colorectal adenomas (CCRAs) since little is known about the differences in their characteristics.

METHODS

Pearson's chi-square test and the Kruskal‒Wallis test were used to compare basic information. MCAR tests and multiple imputation were performed to complete missing values. Multivariate logistic analysis and propensity score matching were used to identify the risk factors for recurrence.

RESULTS

We included 2793 patients (688 with early-onset CCRAs and 2105 with late-onset CCRAs) from January 2017 to December 2021. Patients with early-onset CCRAs had higher levels of Hb, ALB, and triglycerides but lower HDL levels and N/L ratios. Moreover, we found that more early-onset CCRAs were in the left colon than late-onset CCRAs, and the size of early-onset CCRAs was larger. Early-onset CCRAs tended to lack pedicles compared to late-onset CCRAs. Additionally, the ratio of EMR and APC in early-onset CCRAs was higher than that in late-onset CCRAs, and the ratio of ESD and surgery for late-onset CCRAs was higher. We found that age ≥ 50 years, abnormal vessels, drinking alcohol, and DB and ALB levels may be risk factors for recurrence, while the LDL level may be a protective factor. Finally, analysis of cumulative recurrence rates after PSM showed that patients with late-onset CCRAs exhibited higher recurrence rates (P < 0.05).

CONCLUSION

Compared with late-onset CCRAs, early-onset CCRAs were associated with higher triglyceride levels, lower HDL levels, and larger tumor volumes. Age ≥ 50 years, abnormal vessels, alcohol consumption, and DB and ALB levels were independent risk factors for recurrence of CCRAs.

Genetic Defects in Early-Onset Inflammatory Bowel Disease

Inflammatory bowel disease (IBD) represents a spectrum of disease, which is characterized by chronic gastrointestinal inflammation. Monogenic mutations driving IBD pathogenesis are more highly represented in early-onset compared to adult-onset disease. The pathogenic genes which dysregulate host immune responses in monogenic IBD affect both the innate (ie, intestinal barrier, phagocytes) and adaptive immune systems (ie, T cells, B cells). Advanced genomic and targeted functional testing can improve clinical decision making and present increased opportunities for precision medicine approaches in this important patient population.

Genetic and non-genetic risk factors for early-onset pancreatic cancer

BACKGROUND

Early-onset pancreatic cancer (EOPC) represents 5-10% of all pancreatic ductal adenocarcinoma (PDAC) cases, and the etiology of this form is poorly understood. It is not clear if established PDAC risk factors have the same relevance for younger patients. This study aims to identify genetic and non-genetic risk factors specific to EOPC.

METHODS

A genome-wide association study was performed, analysing 912 EOPC cases and 10 222 controls, divided into discovery and replication phases. Furthermore, the associations between a polygenic risk score (PRS), smoking, alcohol consumption, type 2 diabetes and PDAC risk were also assessed.

RESULTS

Six novel SNPs were associated with EOPC risk in the discovery phase, but not in the replication phase. The PRS, smoking, and diabetes affected EOPC risk. The OR comparing current smokers to never-smokers was 2.92 (95% CI 1.69-5.04, P = 1.44 × 10-4). For diabetes, the corresponding OR was 14.95 (95% CI 3.41-65.50, P = 3.58 × 10-4).

CONCLUSION

In conclusion, we did not identify novel genetic variants associated specifically with EOPC, and we found that established PDAC risk variants do not have a strong age-dependent effect. Furthermore, we add to the evidence pointing to the role of smoking and diabetes in EOPC.

BoLA-DRB3*15:01 allele is associated with susceptibility to early enzootic bovine leukosis onset in Holstein-Friesian and Japanese Black cattle

Enzootic bovine leukosis (EBL) is typically observed in cattle older than 3 years, but some cases of onset in cattle younger than 3 years have been reported in Japan. BoLA-DRB3 polymorphisms are associated with susceptibility to EBL onset. However, little is known about the relationship between the polymorphisms and EBL onset in young cattle. In the present study, we performed BoLA-DRB3 genotyping in 59 EBL cattle younger than 3 years (25 Holstein-Friesian and 34 Japanese Black) and compared the results with those of 69 EBL cattle older than 3 years (38 Holstein-Friesian and 31 Japanese Black). The BoLA-DRB3*15:01 allele was detected at a frequency of 37.3 % (48.0 % and 29.4 % in Holstein-Friesian and Japanese Black, respectively) and was identified as an early EBL onset susceptibility allele. Nine EBL cattle younger than 3 years (5 Holstein-Friesian and 4 Japanese Black), but only 1 EBL cattle older than 3 years (1 Holstein-Friesian), had a BoLA-DRB3*15:01/*15:01 homozygous genotype. The frequency of the BoLA-DRB3*15:01 allele occurring with a different allele (BoLA-DRB3*015:01/other) in cattle younger than 3 years was 44.1 % (56.0 % Holstein-Friesian and 35.3 % Japanese Black) and significantly higher than that in cattle older than 3 years (28.9 % Holstein-Friesian and 9.7 % Japanese Black) (P = 0.0013). These results suggest that BoLA-DRB3*15:01/*15:01 and BoLA-DRB3*15:01/other genotypes are early EBL onset susceptibility genotypes. The present findings may contribute to cattle breeding selection.

Age of onset and factors affecting treatment responses in ocular myasthenia gravis

BACKGROUND

Ocular myasthenia gravis (OMG) is an autoimmune disease which causes ptosis, diplopia, or both. It can be categorized as early or late onset, with differing presenting characteristics and prognoses. Currently, there is limited information available to compare characteristics and outcomes in onset groups in Thailand.

OBJECTIVE

To describe and compare baseline characteristics and outcomes in OMG patients classified by onset groups and to investigate the factors associated with the disease, especially in terms of treatment responses classified according to the MGFA Post-Intervention Status (MGFA-PIS).

METHODS

OMG patients diagnosed between January 2014 and March 2021 at Rajavithi Hospital, Thailand, were categorized into 2 groups based on age of onset, and baseline characteristics were analyzed and compared. The treatment responses of each group in terms of time to achievement of minimal manifestations (MM) were analyzed.

RESULTS

Eighty-one patients (38 with early and 43 with late onset) were included, and the mean (SD) follow-up time was 35.85 months (17.25). There was no significant difference between the baseline characteristics of the two groups. A low dose of pyridostigmine was more commonly used in the early-onset group (p = 0.01), while the mean dose of corticosteroids was significantly lower in the late-onset patients (p < 0.001). We found that seropositivity of acetylcholine receptor antibody decreased the odds ratio of achievement of MM (OR 0.185, 95% CI 0.043-0.789, p = 0.023) and receiving a high dose of pyridostigmine (≥ 120 mg/day) increased the odds ratio of achieving it (OR 8.296, 95% CI 2.136-32.226, p = 0.002).

CONCLUSIONS

A higher dose of pyridostigmine may be necessary for achievement of favorable treatment response. AChRAb seropositivity is a predictor for unfavorable treatment response in Thai populations.

Radiosensitivity and early onset cancer

The article is concerned with the radioprotection of a substantial radiosensitive population who present with cancer in early adulthood and will probably be treated with radiotherapy. A theory of radiation-induced health effects based on the induction of DNA double strand breaks is used to associate the radio-sensitivity of carriers of the BRCA1 and BRCA2 genes and the PALB2 gene with the defects in the homologous recombination repair of DNA damage found in the carriers. It is concluded that the defects in homologous recombination repair in these carriers will lead to an increased level of somatic mutations in all their cells and that this increased level of somatic mutations throughout their lifetime is, essentially, the reason that the carriers develop early onset cancer. This is a direct consequence of the more rapid accumulation of the cancer-inducing somatic mutations than the normal, slower accumulation in non-carriers. The radiotherapeutic treatment of these carriers needs to proceed with some care, taking account of their increased radio-sensitivity, and this suggests a need for international recognition and guidance of their radioprotection within the medical profession.&#xD.

Clinical implication of platelet to lymphocyte ratio in early onset preeclampsia: A single-center experience

BACKGROUND

Preeclampsia (PE) is a pregnancy syndrome of undetermined etiology; inflammation was one of the proposed theories for its development.

AIM

To examine the platelet to lymphocyte ratio (PLR), an inflammatory biomarker, as a marker to predict poor maternal-neonatal outcomes in early-onset PE (EoPE).

METHODS

A cross-sectional study enrolled 60 pregnant women with EoPE (at 32-30 wk of gestation) at a university hospital. Demographic criteria and hematological indices were collected, including platelet counts and indices (mean platelet volume and platelet distribution width), PLR, and the Doppler study, which calculated estimated fetal weight (EFW), amniotic fluid index (AFI), resistance index (RI), and pulsatility index (PI). Participants were followed until delivery, where maternal outcomes were recorded, including; delivery mode and reason for cesarean section, and neonatal outcomes, including fetal growth restriction (FGR), meconium-stained liquid, the 5-min Apgar score, and admission to the intensive care unit.

RESULTS

There was a trend of insignificant increases in cesarean sections. Sixty-one-point two percent (37/60) fetuses were admitted to the neonatal care unit; 70.0% of admitted fetuses were meconium-stained liquor, and 56.7% of them had FGR. PLR was positively correlated with AFI and EFW as r = 0.98, 0.97, P < 0.001; PLR showed negative correlations with PI and RI as r = -0.99, -0.98, P < 0.001. The Apgar score and the number of days admitted to the intensive care unit had a positive and negative correlation (0.69, -0.98), P < 0.0001, respectively. Receiver operating characteristic calculated a PLR cutoff value (7.49) that distinguished FGR at 100% sensitivity and 80% specificity.

CONCLUSION

Strong, meaningful relationships between PLR and FGR parameters and a poor neonatal outcome with a significant P value make it a recommendable biomarker for screening EoPE-related complications. Further studies are suggested to see the impact on maternal-neonatal health.

Changes in neurofilament light chain protein (NEFL) in children and adolescents with Schizophrenia and Bipolar Disorder: Early period neurodegeneration

AIM

Neurofilament light chain protein (NEFL), is defined as a structural protein which exists particularly in axones of neurons and is released to the cerum in consequence of neuroaxonal damage. The aim of this study is to investigate the peripheral cerumNEFLlevels of children and adolescents with early onset schizophrenia and bipolar disorder.

METHOD

In this study, we evaluated serum levels of NEFL in children and adolescents (13-17 years) with schizophrenia, bipolar disorder and healthy control group. The study is conducted with 35 schizophrenia, 38 bipolar disorder manic episode patients and 40 healthy controls.

RESULTS

The median age of the patient and control groups was 16 (IQR- Interquartile Range: 2). There was no statistical difference in median age (p = 0.52) and gender distribution(p = 0.53) between groups. NEFL levels of the patients with schizophrenia were significantly higher than the controls. NEFL levels of the patients with bipolar disorder were significantly higher than the controls. Serum levels of NEFL of the schizophrenia were higher than the bipolar disorder; however, the difference was not statistically significant.

CONCLUSION

In conclusion, serum NEFL level, as a confidential marker of neural damage, is increased in the children and adolescents with bipolar disorder and schizophrenia. This result may indicatea degenerative period in neurons of children and adolescents with schizophrenia or bipolar disorder and may play a role in the pathophisiology of these disorders. This result shows that there is neuronal damage in both diseases, but neuronal damage may be more in schizophrenia.

Global and local cortical folding alterations are associated with neurodevelopmental subtype in bipolar disorders: a sulcal pits analysis

BACKGROUND

Analyzing cortical folding may provide insight into the biological underpinnings of neurodevelopmental diseases. A neurodevelopmental subtype of bipolar disorders (BD-ND) has been characterized by the combination of early age of onset and psychotic features. We investigate potential cortical morphology differences associated with this subtype. We analyze, for the first time in bipolar disorders, the sulcal pits, the deepest points in each fold of the cerebral cortex.

METHODS

We extracted the sulcal pits from anatomical MRI among 512 participants gathered from 7 scanning sites. We compared the number of sulcal pits in each hemisphere as well as their regional occurrence and depth between the BD-ND subgroup (N = 184), a subgroup without neurodevelopmental features (BD, N = 77) and a group of healthy controls (HC, N = 251).

RESULTS

In whole brain analysis, BD-ND group have a higher number of sulcal pits in comparison to the BD group. The local analysis revealed, after correction for multiple testing, a higher occurrence of sulcal pits in the left premotor cortex among the BD-ND subgroup compared to the BD and the HC groups.

CONCLUSION

Our findings confirm that BD-ND is associated with a specific brain morphology revealed by the analysis of sulcal pits. These markers may help to better understand neurodevelopment in mood disorder and stratify patients according to a pathophysiological hypothesis.

Age of Onset and Length of Survival of Queensland Patients with Amyotrophic Lateral Sclerosis: Details of Subjects with Early Onset and Subjects with Long Survival

INTRODUCTION

The aims of the study were to document the characteristics of amyotrophic lateral sclerosis (ALS) patients in Queensland, to examine factors influencing age of onset, and survival, and to study those with early-onset (<45 years) disease and those with long (>5 years) survival.

METHODS

We studied subjects seen at the ALS Clinic at the Royal Brisbane and Women's Hospital. We recorded sex, age of onset, region of onset, length of survival, presence of family history, type of disease, and evidence of cognitive involvement. We analysed the influence of these features on age of onset and survival. We analysed the features of patients with early onset of disease and patients with long survival.

RESULTS

There were 855 ALS patients (505 males) in the cohort. The age of onset was lower in males than females, in patients with a family history of ALS compared to those without, and in patients with spinal onset compared to bulbar onset. Early-onset disease was seen in 10% of patients, and had a greater proportion of males, spinal onset, and classical ALS phenotype compared to late-onset disease. Survival was shorter in females, in patients with bulbar onset, and in patients with classical ALS. Long survival was seen in 18% of patients. Patients with long survival had younger age of onset, greater proportion of males, spinal onset, and fewer patients with classical ALS.

CONCLUSION

Our study confirms that ALS is more prevalent in males and that spinal onset is more common than bulbar onset. Males have earlier onset but longer survival. We found that overall, patients with classical ALS have worse survival than ALS variants, but some patients who were considered to have classical ALS had long survival. This study confirms the similarity of ALS in our region to ALS in other geographical regions.

Extremely Early-Onset Frontotemporal Dementia: A Case Report and Literature Review

BACKGROUND

In most cases, the onset of frontotemporal dementia (FTD) occurs between the ages of 45 and 65 years. However, some patients experience an extremely early disease onset.

OBJECTIVE

To investigate the clinical, genetic, and pathological features of extremely early-onset FTD.

METHODS

We conducted a comprehensive clinical, genetic, and neuropathological analysis of a 25-year-old patient experiencing the onset of behavioral variant frontotemporal dementia (bvFTD). In addition, we conducted a literature review and summarized the clinical, genetic, and pathological features of patients with FTD with onset age≤25 years.

RESULTS

The patient was diagnosed with bvFTD; however, there was no family history of FTD, no positive genetic test results and no deposition of TDP43, tau, ubiquitin, and synuclein in the brain. Literature screening identified 18 patients with onset age ≤25 years with FTD. The youngest patient was 14 years of age. Most patients (8/14) had a positive family history. The most common clinical phenotype was the behavioral variant (12/14). Genetic results were reported for 11 patients; the most common pathogenic gene was MAPT (10/12), with four cases of G389 R, two cases of P301 S, one case of G335 S, one case of G335A, one case of G335 V, and one case of L315 R. Pathological results were reported for 13 patients; the most common pathological subtype was tau (8/13).

CONCLUSION

FTD can start at an extremely early age. The most common phenotype of extremely early onset FTD was the behavioral variant, the most common pathogenic gene was MAPT, and the most common neuropathological type was tau.

Lifestyle and metabolic risk factors in patients with early-onset myocardial infarction: a case-control study

AIMS

Family history is a known risk factor for early-onset myocardial infarction (EOMI). However, the role of modifiable lifestyle and metabolic factors in EOMI risk is unclear and may differ from that of older adults.

METHODS

This case-control study included myocardial infarction (MI) patients aged ≤45 years from the Bremen ST-elevation MI Registry and matched controls randomly selected from the general population (German National Cohort) at the same geographical region. Multiple logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for the individual and combined associations of lifestyle and metabolic factors with EOMI risk, overall and according to family history for premature MI.

RESULTS

A total of 522 cases and 1191 controls were included. Hypertension, current smoking, elevated waist-to-hip ratio, and diabetes mellitus were strongly associated with the occurrence of EOMI. By contrast, higher frequency of alcohol consumption was associated with decreased EOMI risk. In a combined analysis of the risk factors hypertension, current smoking, body mass index ≥25.0 kg/sqm, and diabetes mellitus, participants having one (OR = 5.4, 95%CI = 2.9-10.1) and two or more risk factors (OR = 42.3, 95%CI = 22.3-80.4) had substantially higher odds of EOMI compared to those with none of these risk factors, regardless of their family history.

CONCLUSION

This study demonstrates a strong association of smoking and metabolic risk factors with the occurrence of EOMI. The data suggest that the risk of EOMI goes beyond family history and underlines the importance of primary prevention efforts to reduce smoking and metabolic syndrome in young persons.

Early onset, delayed diagnosis and laterality of breast carcinoma: Evidence from a tertiary care hospital

Objectives:

To assess age at onset, delayed diagnosis and laterality of breast carcinoma among women at Debre Markos Comprehensive Specialized Hospital, North West Ethiopia.

Methods:

Hospital-based descriptive study was conducted on 120 breast carcinoma cases at pathology department of Debre Markos Comprehensive Specialized Hospital, from October 2019 to December 2021. The women aware of symptoms until first medical consultation time was asked. The height and weight of the women were measured using the height and weight scale. The attending physician examined both breasts and regional lymph nodes. Pathological features of breast carcinomas were recorded when biopsy results arrived at the pathology department. Data were entered in Epi data version 3.1. Then, it was exported to SPSS version 25.0 statistical software for analysis.

Results:

Mean age of women was 39.9 ± 11.6 years, and median age was 38 years. Most women, 87 (72.5%) were aged less than 46 years. One hundred three (85.8%) women had complained breast lump pain for greater than 3 months before diagnosis. About 61 (50.8%) women had left breast carcinomas; 44 (36.7%) had right breast carcinomas and 15 (12.5%) had bilateral breast carcinomas. Of total, 53 (44.2%) cases were invasive ductal carcinomas; 41 (34.2%) had ductal carcinoma in situ; 14 (11.7%) were invasive lobular carcinomas; 8 (6.7%) were lobular carcinoma in situ and only 4 (3.3%) cases were mixed carcinomas.

Conclusion:

In this study, about two-third of the cases had early onset breast carcinoma. Most of the cases had delayed diagnosis of breast carcinoma. More than half of the cases had left breast carcinoma.

Late-onset familial mediterranean fever: single-center experience and literature review

Familial Mediterranean fever (FMF) is a hereditary, autoinflammatory disease characterized by recurrent fever and serositis attacks. The disease onset occurs before 20 years of age in 90% of patients and rarely after the 4th decade. The aim of this study is to screen our FMF patient pool for patients with disease onset after age of 40 and to compare them to patients with early onset with regard to clinical and genetic features. The charts of 2020 patients registered in our FMF center in the years 2008-2017 were screened with regard to age of disease onset. Patients with disease onset after the age of 40 were considered as late-onset group (Group 1). The control group (Group 2) consisted of patients with a disease onset before the age of 20 who were randomly selected from the patient pool with twice the number of probands. Demographic, clinical and genetic data were recorded. Out of 2020 patients, the attacks of FMF had started after the fourth decade in 41 patients (2.02%), (Group 1). The male to female ratio was 1:1.7 in both groups. The delay of diagnosis was 5.6 ± 5.75 years in group 1, 10.7 ± 12.3 years in group 2. The only significant difference with regard to clinical features between two groups was the frequency of fever, which was present in 26 (63.4%) patients in group 1 and 67 (81.7%) in group 2 (p = 0.026). M694V mutation was more prevalent among early-onset group whereas exon 2 variants were more frequent in patients with late onset. The mean colchicine dose in the last 6 months was 1.38 ± 0.64 mg in group 1, and 1.61 ± 0.47 mg in group 2. FMF may start after 40 years of age in approximately 2% of the patients. Lower frequency of fever, lower daily colchicine dose and lower prevalence of exon 10 mutations point out that FMF patients with a disease onset after 40 years of age experience a milder disease compared to those with an onset before the second decade of life.

Exploring the association between specific genes and the onset of idiopathic scoliosis: a systematic review

Background

Idiopathic Scoliosis (IS) is the most common spinal deformity in adolescents, accounting for 80% of all spinal deformities. However, the etiology remains uncertain in most cases, being identified as Adolescent Idiopathic Scoliosis (AIS). IS treatments range from observation and sport to bracing or surgery. Several risk factors including sex and familiarity, have been linked with IS. Although there are still many uncertainties regarding the cause of this pathology, several studies report a greater incidence of the defect in families in which at least one other first degree relative is affected. This study systematically reviews the available literature to identify the most significant genes or variants related to the development and onset of IS.

Methods

The research question was formulated using a PIOS approach on the following databases: Medline, Embase, Cinahl, Scopus, Web of Science and Google Scholar. The search was performed from July to August 2021, and articles from the inception of the database to August 2021 were searched.

Results

24 of the 919 initially identified studies were included in the present review. The 24 included studies observed a total of 16,316 cases and 81,567 controls. All the considered studies stated either the affected gene and/or specific SNPs. CHD7, SH2B1, ESR, CALM1, LBX1, MATN1, CHL1, FBN1 and FBN2 genes were associated with IS development.

Conclusions

Although association can be found in some candidate genes the field of research regarding genetic association with the onset of IS still requires more information.

Predictive Factors for Conversion to Dementia in Individuals with Early-Onset Mild Cognitive Impairment

INTRODUCTION

There is little research on factors predicting conversion to dementia in early-onset mild cognitive impairment (eoMCI), a transitional stage between healthy ageing and dementia in individuals below the age of 65. We aimed to examine whether sociodemographic and clinical factors at initial presentation predicted dementia progression in a cohort of eoMCI patients attending a memory service, at a university teaching hospital in the UK.

METHODS

This is a retrospective case note study of individuals diagnosed with eoMCI between 2000 and 2013 at the Younger Person's Memory Service (YPMS) in Leicestershire, England. Data collected at assessment included social factors, demographic characteristics, and medical and psychiatric history, as well as standardized cognitive assessment scores. Variables were analysed using χ2 or independent sample t tests to identify associations. A Cox regression survival analysis was done to identify predictive factors for dementia conversion. An ROC analysis for total CAMCOG was used to investigate sensitivity and specificity for dementia converters versus non-converters.

RESULTS

Out of 531 subjects who attended YPMS, 65 patients were given a diagnosis of eoMCI (47.7% female; mean age 56.4 ± 7.54 years). Of these, 21 (32.3%) converted to dementia during their course within the service. Comparison between subgroups revealed a significant association between dementia conversion and higher years of education and lower MMSE and CAMCOG (total and subscale) scores at baseline. Smoking history, alcohol use, or medical history such as diabetes or heart disease were not associated with conversion. Cox regression survival analysis showed higher education in years and lower total CAMCOG scores were significant predictors for conversion. Lower scores on the recent memory, remote memory, learning memory, and executive function subscales of the CAMCOG were also significant predictors for conversion. ROC curve analysis for total CAMCOG demonstrated that the best detection of dementia converters can be achieved with a cutoff score of 90.5/107 (sensitivity of 76.2% and specificity of 68.2%). Area under the curve was 0.808 (95% CI: 0.697-0.920).

CONCLUSION

More years in education and lower cognitive scores on CAMCOG at initial assessment are associated with progression to dementia from eoMCI. Further research is required to explore these predictive factors more.

Altered Closed State Inactivation Gating in Kv4.2 Channels Results in Developmental and Epileptic Encephalopathies in Human Patients

Kv4.2 subunits, encoded by KCND2, serve as the pore-forming components of voltage-gated, inactivating I_SA K⁺ channels expressed in the brain. I_SA channels inactivate without opening in response to subthreshold excitatory input, temporarily increasing neuronal excitability, the back propagation of action potentials, and Ca²⁺ influx into dendrites, thereby regulating mechanisms of spike timing-dependent synaptic plasticity. As previously described, a de novo variant in Kv4.2, p.Val404Met, is associated with an infant-onset developmental and epileptic encephalopathy (DEE) in monozygotic twin boys. The p.Val404Met variant enhances inactivation directly from closed states, but dramatically impairs inactivation after channel opening. We now report the identification of a closely related, novel, de novo variant in Kv4.2, p.Val402Leu, in a boy with an early-onset pharmacoresistant epilepsy that evolved to an epileptic aphasia syndrome (Continuous Spike Wave during Sleep Syndrome). Like p.Val404Met, the p.Val402Leu variant increases the rate of inactivation from closed states, but significantly slows inactivation after the pore opens. Although quantitatively the p.Val402Leu mutation alters channel kinetics less dramatically than p.Val404Met, our results strongly support the conclusion that p.Val402Leu and p.Val404Met cause the clinical features seen in the affected individuals and underscore the importance of closed state inactivation in I_SA channels in normal brain development and function.

The amyloid plaque proteome in early onset Alzheimer's disease and Down syndrome

Amyloid plaques contain many proteins in addition to beta amyloid (Aβ). Previous studies examining plaque-associated proteins have shown these additional proteins are important; they provide insight into the factors that drive amyloid plaque development and are potential biomarkers or therapeutic targets for Alzheimer's disease (AD). The aim of this study was to comprehensively identify proteins that are enriched in amyloid plaques using unbiased proteomics in two subtypes of early onset AD: sporadic early onset AD (EOAD) and Down Syndrome (DS) with AD. We focused our study on early onset AD as the drivers of the more aggressive pathology development in these cases is unknown and it is unclear whether amyloid-plaque enriched proteins differ between subtypes of early onset AD. Amyloid plaques and neighbouring non-plaque tissue were microdissected from human brain sections using laser capture microdissection and label-free LC-MS was used to quantify the proteins present. 48 proteins were consistently enriched in amyloid plaques in EOAD and DS. Many of these proteins were more significantly enriched in amyloid plaques than Aβ. The most enriched proteins in amyloid plaques in both EOAD and DS were: COL25A1, SMOC1, MDK, NTN1, OLFML3 and HTRA1. Endosomal/lysosomal proteins were particularly highly enriched in amyloid plaques. Fluorescent immunohistochemistry was used to validate the enrichment of four proteins in amyloid plaques (moesin, ezrin, ARL8B and SMOC1) and to compare the amount of total Aβ, Aβ40, Aβ42, phosphorylated Aβ, pyroglutamate Aβ species and oligomeric species in EOAD and DS. These studies showed that phosphorylated Aβ, pyroglutamate Aβ species and SMOC1 were significantly higher in DS plaques, while oligomers were significantly higher in EOAD. Overall, we observed that amyloid plaques in EOAD and DS largely contained the same proteins, however the amount of enrichment of some proteins was different in EOAD and DS. Our study highlights the significant enrichment of many proteins in amyloid plaques, many of which may be potential therapeutic targets and/or biomarkers for AD.

Patients with Early-Onset Colorectal Cancer Have an Increased Risk of Second Primary Malignancy

BACKGROUND

While overall colorectal cancer (CRC) rates in the USA are declining, the incidence of early-onset CRC (eoCRC) under age 50 is increasing. The aim of this study was to examine the risk of a second primary malignancy (SPM) in individuals with eoCRC, and how this risk compares to those with late-onset CRC (loCRC).

METHODS

We used data from the Surveillance, Epidemiology, and End Results Program database to examine the risk of SPM after a diagnosis of eoCRC. Standardized incidence ratios (SIR) were used to estimate the risk of SPM after eoCRC and loCRC in comparison with the risk of malignancy in the general population.

RESULTS

Compared to the general population, individuals with eoCRC, but not loCRC, had an increased lifetime risk of SPM (SIR 1.42, 95% CI 1.37-1.48 and SIR 1.00, 95% CI 0.99-1.02, respectively), and locations at highest risk were the small intestine, ureter, rectum, and colon. The risk of SPM after eoCRC was similar in men and women, but higher in non-whites compared to whites and higher in those with a lower area-level median household income. The risk of SPM following eoCRC was high in the first 5 years after diagnosis (SIR 2.44, 95% CI 2.24-2.66) and, in a birth cohort analysis, was found to be increasing over time.

CONCLUSIONS

Individuals with eoCRC have a lifetime risk of SPM nearly 50% higher than the general population. The risk of SPM is highest in the first 5 years after diagnosis and is increasing over time.

FOLFOXIRI and bevacizumab in patients with early-onset metastatic colorectal cancer. A pooled analysis of TRIBE and TRIBE2 studies

BACKGROUND

We performed a pooled analysis of TRIBE and TRIBE2 studies to assess the efficacy and safety of the intensification of upfront chemotherapy backbone - from doublets to the triplet FOLFOXIRI - in combination with bevacizumab (bev) in patients with early-onset metastatic colorectal cancer (EO-mCRC; aged <50 years) and to explore whether EO-mCRCs have a peculiar tumour genomic profiling.

MATERIALS AND METHODS

Subgroup analyses according to age (<50 versus ≥50 years) and treatment (FOLFOXIRI/bev versus doublets/bev) were carried out for rates of any grade and grade ≥3 (≥G3) overall and singular adverse events, progression-free survival (PFS), overall survival (OS) and objective response rate (ORR). Tumour genomic profiling was obtained using a DNA-based next-generation sequencing platform.

RESULTS

Of 1187 patients included, 194 (16%) patients were aged <50 years. Females were more frequently diagnosed with EO-mCRC (P = 0.04). Patients aged <50 years showed a lower risk of ≥G3 neutropenia (P = 0.07), diarrhoea (P = 0.04), asthenia (P = 0.008) and a higher risk of any grade nausea (P < 0.01) and vomiting (P < 0.01). Patients receiving FOLFOXIRI/bev more frequently experienced ≥G3 chemotherapy-related adverse events respect to doublets/bev, regardless of age (P_interaction = 0.60). FOLFOXIRI/bev was associated to a lower incidence of neutropenia (P = 0.04) and asthenia (P = 0.01) in patients <50 years old, than those aged ≥50 years. PFS, OS and ORR did not differ according to age (PFS P = 0.81, OS P = 0.44, ORR P = 0.50) and no interaction between age and the benefit from the intensification of upfront chemotherapy was observed (PFS P_interaction = 0.72, OS P_interaction = 0.54, ORR P_interaction = 0.65). Genomic profiling was assessed in 296 patients, showing an enrichment of FBXW7 and POLE mutations in EO-mCRC.

CONCLUSIONS

Upfront FOLFOXIRI/bev shows a favourable efficacy/safety balance in EO-mCRC.

Association between early-onset affective disorders and hypothyroidism in a larger number of psychiatric drug-free patients

AIMS

We aimed to assess the association between early onset of affective disorders and hypothyroidism in a larger number of psychiatric drug-free patients with bipolar disorder (BD) or major depressive disorder (MDD).

METHODS

Early onset of affective disorders was defined as BD and MDD developed before the age of 22 years. The hypothyroidism hierarchy were diagnosed biochemically and included subclinical and overt hypothyroidism in this study. Demographic and clinical data including diagnosis, illness duration and thyroid function parameters (TSH, T4, FT4, T3 and FT3) at admission were collected from patients' records. Adjusted odds ratio (OR) and 95% confidence interval (CI), which were estimated by logistic regression model, were used to assess the association between early-onset affective disorder and hypothyroidism.

RESULTS

The prevalence of hypothyroidism in early-onset affective disorders was higher than that in late-onset patients (in BD, 9.4% vs. 6.2%, χ² = 6.020, P = 0.014; and in MDD 12.7% vs. 6.6%, χ² = 13.295, P < 0.001). Early-onset affective disorders were 2.097 times (95% CI: 1.409-3.123) more likely to have hypothyroidism compared with late-onset patients, after adjustment for age, gender, duration of illness and mood episode (adjusted OR: 1.965, 95% CI: 1.198-3.221 in BD, and adjusted OR: 2.831, 95% CI: 1.378-5.817 in MDD, respectively).

LIMITATION

Because of the cross-sectional design of this study, we were unable to sort out causality between early-onset affective disorders and hypothyroidism.

CONCLUSION

Early-onset affective disorder may be associated with higher prevalence of hypothyroidism.

Early onset of efficacy with fremanezumab in patients with episodic and chronic migraine: subanalysis of two phase 2b/3 trials in Japanese and Korean patients

Background

Early onset of action has become recognized as an important efficacy feature of preventive migraine treatment, which can help overcome adherence issues commonly associated with older medications. Preventive treatments that target the calcitonin gene-related peptide (CGRP) or the CGRP receptor have been previously shown to provide early onset of action.

Methods

This subanalysis of primary endpoints of two separate phase 2b/3 studies sought to determine the onset of action of fremanezumab in Japanese and Korean patients with episodic migraine (EM) and chronic migraine (CM).

Results

In EM patients (n = 357), both fremanezumab quarterly and fremanezumab monthly led to greater reductions in weekly migraine days (days/week) than placebo from the first week after the initial injection and thereafter during the remainder of the study period. Similarly, CM patients (n = 571) had a greater reduction in headache days of at least moderate severity (days/week) with fremanezumab (total) than placebo. The percentage of patients with a migraine day (EM) or headache day at least moderate severity (CM) was lower in those treated with fremanezumab than placebo and this effect was apparent from as early as Day 2 (1 day after first injection).

Conclusions

These results suggest that fremanezumab has an early onset of action, as noted in previous post hoc analyses of anti-CGRP monoclonal antibodies.

Presentation of Mucopolysaccharidosis As Very Early Onset Schizophrenia Like Illness in Psychiatry Settings

Schizophrenia is very rare before the age of 13, which is known as very early onset schizophrenia. There are few reports which document cases of schizophrenia before 5 years of age. Childhood onset schizophrenia has more chronic course characterized by sever social and cognitive consequences and increased negative and disorganization symptoms. Although diagnostic criteria of schizophrenia according to DSM5 are same as of adult onset but it's very difficult to explore psychopathology such as delusion and hallucination which depend upon cognitive development of the child. Further, the diagnosis of early onset schizophrenia is difficult because of similarity with neurological and metabolic disorder of childhood. This warrants comprehensive evaluation of such cases by multidisciplinary team consisting pediatrician, neurologist and psychiatrist.

Colorectal cancer patients in a tertiary hospital in Indonesia: Prevalence of the younger population and associated factors

BACKGROUND

An increasing trend in colorectal cancer (CRC) occurring at younger ages has been observed worldwide, even though incidence is declining in the general population. Most currently available guidelines still recommend CRC screening for older populations, despite an alarming rise in early-onset CRC incidence. Risk stratification is necessary to further determine the population most at risk for early-onset CRC. However, epidemiological data on related clinical characteristics and potential risk factors, especially in developing countries, have not been widely reported.

AIM

To investigate the prevalence, demographics, clinicopathologic features, and associated factors of young-onset CRC patients in a tertiary hospital in Indonesia.

METHODS

Patients undergoing colonoscopy examination between 2008 and 2019, yielding a diagnosis of CRC were identified from medical records. The subjects were classified into two groups according to their age at diagnosis, namely early-onset (18-49 years old) and late-onset (≥ 50-years-old). Demographic data, characteristics, and risk factors of both onset age groups were evaluated using the chi-square and Fisher’s exact test.

RESULTS

Among 495 CRC patients confirmed by histopathology, 205 (41.4%) were classified as early-onset and 290 (58.6%) as late-onset. Most subjects in the early-onset CRC group were male (53.7%), with 89.8% displaying adenocarcinoma histopathology. A majority (78%) of the early-onset CRC patients had left-sided tumors, with the rectum (41%) and rectosigmoid (17.6%) being the most common sites. Abdominal pain was the most frequent symptom in the early-onset CRC patients (55.6%), which was significantly higher than that in the late-onset CRC patients (43.8%, P < 0.05). Early-onset CRC cases were more likely to be underweight (34.6% vs 20.0%, P < 0.001) compared to late-onset CRC cases. The proportion of subjects with suspected hereditary nonpolyposis colorectal cancer (HNPCC) was also higher in the early-onset CRC group than in the late-onset age group (9.3% vs 4.1%, P < 0.05). However, no difference was observed in the parental or family histories of CRC cases.

CONCLUSION

Early-onset CRC patients were more likely to have abdominal pain, underweight status, and HNPCC suspicion than late-onset CRC patients.

Early-Onset Versus Late-Onset Psoriasis: A Comparative Study of Clinical Variables, Comorbidities, and Association with HLA CW6 in a Tertiary Care Center

Background:

Psoriasis is a chronic inflammatory diseaseresulting from a complex interplay of genetic and environmental factors affecting the skin, nail and joints. Two distinct types of psoriasis are said to exist (i) early onset psoriasis (EOP), beginning before the age of 40 years and (ii) late onset psoriasis (LOP), beginning ≥40 years; with the presence of Human lymphocyte antigen (HLA) Cw6, present in majority of patients with early onset. Several studies demonstrated clinical and genetic differences between EOP and LOPamong European and East Asian populations. Lack of similar study in the Indian population has prompted us to undertake the present work.

Aims and Objectives:

(i) To compare the clinical patterns of early onset and late onset psoriasisin patients attending the Dermatology outpatientdepartment (OPD) and admitted in the in-patient department (IPD). (ii) To analyze the association age of onset with presence of HLA Cw6.

Materials and Methods:

It was an institution-based, descriptive, cross-sectional study. Consecutive patients with psoriasis at the OPD and IPD of the department of Dermatology during the study period, were recruited in the study after obtaining informed consents. Detailed history was obtained regarding the disease, co-morbidities and complications. Through physical examination was carried out, PASI was calculated and blood samples were drawn fromconsenting adult patients (age>/=18 years) to study the presence of Cw6.

Results:

The study population (n=250) wasbroadly divided into “Early onset psoriasis(EOP)” (n=138) and Late onset psoriasis (LOP)” (n=112).Significant higher occurrence of positive family history, nail involvement and koebnerization were found in EOP, but such differences were absent considering the types, patterns, joint involvement, severity and HLACW6 positivity.

Conclusion:

This study supports the concept of two subtypes of psoriasis based on age of onset showing different clinical and evolutionary features.

Early Onset Acute Coronary Artery Occlusion After Pembrolizumab in Advanced Non-Small Cell Lung Cancer: A Case Report

Myocarditis, arrhythmia, and cardiomyopathy are the most reported acute cardiotoxicities in cancer patients receiving immune checkpoint inhibitor (ICI) therapy. But it is not clear whether ICI can cause acute coronary occlusive disease. We reported acute coronary artery occlusion in an 83-year-old male non-small cell lung cancer (NSCLC) patient after 2 days of pembrolizumab infusion. This patient had a server-underlying three-vessel coronary artery disease without symptoms. The patient was discharged from the hospital two weeks after percutaneous coronary intervention. Pembrolizumab may cause destabilization of severely stenosed atherosclerotic plaques, which contributes to acute myocardial infarction. We should take more caution about lung cancer patients with baseline coronary disease when treat with ICI. CRP may be a useful predictor factor of early-onset coronary events in these patients.

Confirmation of early non-bulbar onset of amyotrophic lateral sclerosis in Spanish league soccer players

OBJECTIVE

Sports-related activity has been proposed as a risk factor for ALS, particularly among professionals playing American football and soccer, with a reported prevalence between two and forty times higher than the general population. Early onset (by two decades) was described among Italian soccer players as early as 2005. This study aims to characterise the phenotype of seven Spanish retired professional and semi-professional soccer players.

METHODS

The cases were identified using the following sources: (i) personal archives from a leading ALS Unit, (ii) PubMed and specialised websites, and (iii) self-reports of patients in the media. Age and site of onset, survival time, history of trauma, playing position and time between retirement and first symptoms were investigated for soccer players in the Spanish league diagnosed between 2000 and 2020.

RESULTS

Seven ALS cases were identified. The mean age at onset was 41.5 years (SD 9.2, median 45.5, range 31.5-51.2). Onset was bulbar in one individual, while six experienced spinal onset. Three patients had the flail arm syndrome variant. Two cases were goalkeepers, two defenders and three midfielders. Four had a history of trauma (two serious). Survival time for the two deceased patients was 71.8 months. Mean time between retirement and first symptoms was 9.4 years (SD 8.0, median 15.2, range 0.1-17.5).

CONCLUSIONS

Our study has the largest sample size of non-Italian league soccer professionals and semi-professionals, and our results corroborate early onset (by 23.7 years). Unlike the Italian cohorts, bulbar onset is rare, and upper limb onset is most common.

Parkinson mice show functional and molecular changes in the gut long before motoric disease onset

BACKGROUND

There is increasing evidence that Parkinson's disease (PD) might start in the gut, thus involving and compromising also the enteric nervous system (ENS). At the clinical onset of the disease the majority of dopaminergic neurons in the midbrain is already destroyed, so that the lack of early biomarkers for the disease represents a major challenge for developing timely treatment interventions. Here, we use a transgenic A30P-α-synuclein-overexpressing PD mouse model to identify appropriate candidate markers in the gut before hallmark symptoms begin to manifest.

METHODS

Based on a gait analysis and striatal dopamine levels, we defined 2-month-old A30P mice as pre-symptomatic (psA30P), since they are not showing any motoric impairments of the skeletal neuromuscular system and no reduced dopamine levels, but an intestinal α-synuclein pathology. Mice at this particular age were further used to analyze functional and molecular alterations in both, the gastrointestinal tract and the ENS, to identify early pathological changes. We examined the gastrointestinal motility, the molecular composition of the ENS, as well as the expression of regulating miRNAs. Moreover, we applied A30P-α-synuclein challenges in vitro to simulate PD in the ENS.

RESULTS

A retarded gut motility and early molecular dysregulations were found in the myenteric plexus of psA30P mice. We found that i.e. neurofilament light chain, vesicle-associated membrane protein 2 and calbindin 2, together with the miRNAs that regulate them, are significantly altered in the psA30P, thus representing potential biomarkers for early PD. Many of the dysregulated miRNAs found in the psA30P mice are reported to be changed in PD patients as well, either in blood, cerebrospinal fluid or brain tissue. Interestingly, the in vitro approaches delivered similar changes in the ENS cultures as seen in the transgenic animals, thus confirming the data from the mouse model.

CONCLUSIONS

These findings provide an interesting and novel approach for the identification of appropriate biomarkers in men.

Effects of thymectomy on late-onset non-thymomatous myasthenia gravis: systematic review and meta-analysis

BACKGROUND

The effects of thymectomy on late-onset non-thymomatous myasthenia gravis (NTMG) remain controversial. The objective of this study was to conduct a systematic review in order to answer two questions pertinent to late-onset NTMG: (1) do patients with late-onset NTMG experience the same effects from thymectomy as their early-onset counterparts? (2) Compared with conservative treatment, does thymectomy have any benefits for late-onset NTMG patients?

METHODS

We searched the PubMed, EMBASE, and Cochrane Library databases for studies published from January 1, 1950 to March 10, 2021. Outcomes were measured via clinical stable remission/pharmacological remission (CSR/PR) and improvement rates. We used Stata software to analyze the data.

RESULTS

We ultimately included a total of 12 observational articles representing the best evidence answering the questions of our study objective. Of these, nine studies, which included 896 patients overall (766 early-onset and 230 late-onset), compared postoperative outcomes between early- and late-onset NTMG. The remaining three articles, which included 216 patients (75 in the thymectomy group and 141 in the conservative-treatment group), compared thymectomy with conservative treatment for late-onset NTMG. The early- versus late-onset NTMG studies demonstrated that patients in the former category were 1.95× likelier than their late-onset counterparts to achieve clinical remission (odds ratio [OR] 1.95; 95% confidence interval [CI] 1.39-2.73; I2 = 0%). No difference was seen in improvement or remission + improvement rates between these two groups. When comparing thymectomy with conservative treatments in late-onset NTMG patients, neither did we observe any difference in CSR/PR.

CONCLUSION

We found that late-onset NTMG patients had a lower chance of achieving CSR after thymectomy than early-onset patients. Thymectomy in late-onset NTMG also yielded no benefit to CSR or PR compared with conservative treatments. In late-onset NTMG patients, thymectomy should therefore be performed with caution, and the appropriate cutoff between early- and late-onset MG should be further explored in order to tailor and execute the proper therapeutic strategies.

Early onset of effect following galcanezumab treatment in patients with previous preventive medication failures

Background

Galcanezumab is a monoclonal antibody (mAb) that binds calcitonin gene-related peptide (CGRP) and is indicated for the preventive treatment of migraine. Galcanezumab demonstrated early onset of effect in patients with migraine but it is unknown whether the same holds true for patients who have not benefited from multiple prior migraine preventives.

Methods

Patients with episodic or chronic migraine from a 3-month, randomized, double-blind, placebo-controlled, phase 3b study (CONQUER) who had 2 to 4 migraine preventive medication category failures in the past 10 years were randomized 1:1 to placebo (N = 230) or galcanezumab 120 mg/month (240 mg loading dose; N = 232). In this post-hoc analysis, change from baseline in number of monthly and weekly migraine headache days was assessed. Monthly onset of effect was the earliest month at which significant improvement with galcanezumab compared to placebo was achieved and maintained at all subsequent months. Weekly onset was the initial week at which statistical separation was achieved and maintained at all subsequent weeks during that month. Proportion of patients with migraine headache days in the first week of treatment, and patients achieving ≥50%, ≥75%, and 100% response by month and week were also assessed.

Results

Galcanezumab-treated patients had a significantly greater reduction in monthly migraine headache days starting at month 1, which remained significant for all subsequent months compared to placebo (all p ≤ 0.0001, month 1 mean change from baseline: placebo − 0.7; galcanezumab − 4.0). Weekly migraine headache days was significantly reduced in galcanezumab-treated patients starting at week 1 and continued for each subsequent week of month 1 compared to placebo (all p < 0.01, week 1 mean change from baseline: placebo − 0.2; galcanezumab − 1.1). A significantly smaller percentage of patients had a migraine headache on the first day after galcanezumab treatment compared to placebo (28.4% vs 39.2%) and at each subsequent day during week 1 (all p < 0.05). A greater proportion of galcanezumab-treated patients achieved ≥50%, ≥75%, and 100% response at months 1–3 (all p < 0.05) and at weeks 1–4 of month 1 compared to placebo (all p < 0.01).

Conclusion

Galcanezumab showed early onset of effect beginning the day after treatment initiation in patients who had not previously benefited from migraine preventive treatments.

A case of hypertensive disorders of pregnancy that developed at 9 weeks of gestation

Preeclampsia and superimposed preeclampsia usually develop after 20 weeks of gestation. We report a case of a 35-year-old Japanese woman who developed hypertensive disorders of pregnancy (HDP) before 20 weeks of gestation. She presented with hypertension and proteinuria at 9 and 11 weeks of gestation, respectively, and developed nephrotic syndrome at 17 weeks of gestation. She did not have definite hypertension or urinary abnormalities before pregnancy. The patient was serologically positive for the antinuclear antibody. However, the complement levels were normal and anti-phospholipid antibody was not detected. A renal biopsy performed at 18 weeks of gestation showed diffuse endotheliosis and tip lesions of secondary focal segmental glomerulosclerosis but no hypertensive changes of the arterioles. Although electron microscopic examination showed electron-dense deposits in the subendothelial lesions, they were considered nonspecific plasma exudation by mass spectrometry. An abortion was performed at 20 weeks gestation because the patient's congestive symptoms due to nephrotic syndrome had worsened and marked fetal growth restriction was observed. After delivery, the patient's symptoms resolved immediately without any additional treatment; however, continuous antihypertensive medication was required. Finally, the patient was diagnosed with HDP based on the renal biopsy findings and her clinical course after delivery. Compared to previous reports, this case describes the earliest onset of HDP. Thus, HDP should be considered as a differential diagnosis in pregnant women with hypertension or proteinuria presenting with symptoms before 20 weeks of gestation.

Abnormal bone mineral density and content in girls with early-onset anorexia nervosa

BACKGROUND

Early-onset anorexia nervosa (EO-AN) represents a significant clinical burden to paediatric and mental health services. The impact of EO-AN on bone mineral abnormalities has not been thoroughly investigated due to inadequate control for pubertal status. In this study, we investigated bone mineral abnormalities in girls with EO-AN regardless of pubertal development stage.

METHOD

We conducted a cross-sectional study of 67 girls with EO-AN (median age = 12.4 [10.9-13.7 years]) after a median duration of disease of 1.3 [0.6-2.0] years, and 67 healthy age-, sex-, pubertal status- matched control subjects. We compared relevant bone mineral parameters between groups: the total body bone mineral density [TB-BMD], the lumbar spine BMD [LS-BMD], the total body bone mineral content [TB-BMC] and the ratio of the TB-BMC to lean body mass [TB-BMC/LBM].

RESULTS

TB-BMD, TB-BMC, LS-BMD and TB-BMC/LBM were all significantly lower in patients with AN compared to controls. In the EO-AN group, older age, later pubertal stages and higher lean body mass were associated with higher TB-BMC, TB-BMD, and LS-BMD values.

DISCUSSION

Girls with EO-AN displayed deficits in bone mineral content and density after adjustment for pubertal maturation. Age, higher pubertal stage and lean body mass were identified as determinants of bone maturation in the clinical population of patients with EO-AN. Bone health should be promoted in patients, specifically in those with an onset of disorder before 14 years old and with a delayed puberty.

Elderly Bipolar Disorder

PURPOSE OF REVIEW

With more individuals reaching older ages, bipolar disorder is no longer a rare illness in the elderly. Despite the growing number of the older individuals with the illness, there are few studies that focus on bipolar disorder in the geriatric population leading to gaps in clinical knowledge and treatment. The aim of this study is therefore to increase understanding by summarizing the available literature on the epidemiology, symptomatology, comorbidities, and treatment recommendations in this cohort, as well as to suggest areas for future clinical and research focus.

RECENT FINDINGS

The prevalence of bipolar disorder is underestimated in the geriatric population. The illness maintains the main features observed in the other cohorts but it also has some specific characteristics in the older individuals. In this cohort, psychiatric and medical comorbidities tend to be the rule rather than the exception. Higher rates of cognitive impairments than age- and education-matched groups present across all of the illness phases. Treatment is more challenging in the elderly individuals due to higher rates of comorbidities and susceptibility to medication side effects. Two cohorts of older individuals with bipolar disorder can be recognized, those with symptoms that start earlier in life and those with late-life onset. Although the knowledge about elderly bipolar disorder is only slowly growing, it is increasingly recognized as an illness with unique features. More work is needed to improve diagnosis and to establish treatment guidelines.

Trauma and psychopathology associated with early onset BPD: an empirical contribution

Prodromal symptoms of borderline personality disorder (BPD) often arise in young age, especially in early adolescence. Several factors for early BPD onset have been identified to consent a precocious detection of high-risk population. The present study is aimed: (1) to identify what psychopathological, traumatic, and functional factors are significantly associated to early onset in a sample of BPD patients and (2) to evaluate what factors are associated to the time interval between symptoms onset and first psychiatric visit (Δ age). Participants were enrolled from BPD outpatients attending the Center for Personality Disorder of the University of Turin, Italy. Patients were tested with assessment instruments for specific BPD symptoms, exposure to traumatic experiences, global functioning, and perception of quality of life. All variables that were found significant at a bivariate analysis were included in two multiple regressions (stepwise backward), with the age of onset and the Δ age as dependent variables. Significance level was P ≤ 0.05. Seventy patients were included in the study (68 completers). Factors that were found related to age of onset were: CTQ-SF emotional abuse (P = 0.001); ACE-IQ bully victimization (P = 0.005), alcohol/drug abuser in the household (P = 0.001), and physical neglect (P = 0.006); BIS non-planning impulsivity (P = 0.005); and SOFAS score (P = 0.033). Factors that were found related to Δ age were: ACE-IQ total score (P = 0.001) and BIS total score (P = 0.001). Earlier onset of BPD is mainly associated to traumatic events, including abuse, neglect, dysfunction in household environment, and bullying. Earlier onset is also related to a worse social functioning. Among BPD symptoms only non-planning impulsivity was found associated to early onset. A higher number of traumatic events and worse impulsive dyscontrol induce a significant reduction of the time interval between onset and first psychiatric observation.

Relationship of comorbid personality disorders to prospective outcome in bipolar disorder

Introduction There is a high incidence of Axis II personality disorders (PDs) in patients with bipolar illness, but their influence on the prospectively measured course of bipolar disorder has been less well explicated. Methods 392 outpatients with bipolar disorder gave informed consent, completed the PDQ4 99 item personality disorder rating, and where clinically rated during at least one year of prospective naturalistic treatment. They were classified as Well on admission (N = 64) or Responders (N = 146) or Non-responders (N = 182) to treatment for at least six months. Results Patients who were positive for PDs were very infrequently represented in the category of Well on admission. In addition, patients with borderline, depressive, and schizoid PDs were significantly more likely to be Non-responders compared to Responders upon prospective naturalistic treatment in the network. Conclusions Patients with bipolar disorder and comorbid PDs were in general less likely to be Well from treatment in the community at network entry or to be a Responder to prospective treatment in the network. Therapeutic approaches to patients with PDs deserve specific study in an attempt to achieve a better long-term course of bipolar disorder.

"I feel good when I drink"-detecting childhood-onset alcohol abuse and dependence in a Ugandan community trial cohort

BACKGROUND

Alcohol, substance use, and mental health disorders constitute major public health issues worldwide, including in low income and lower middle-income countries, and early initiation of use is an important predictor for developing substance use disorders in later life. This study reports on the existence of childhood alcohol abuse and dependence in a sub-study of a trial cohort in Eastern Uganda.

METHODS

The project SeeTheChild-Mental Child Health in Uganda (STC) included a sub-study of the Ugandan site of the study PROMISE SB: Saving Brains in Uganda and Burkina Faso. PROMISE SB was a follow-up study of a trial birth cohort (PROMISE EBF) that estimated the effect that peer counselling for exclusive breast-feeding had on the children's cognitive functioning and mental health once they reached 5-8 years of age. The STC sub-study (N = 148) used the diagnostic tool MINI-KID to assess mental health conditions in children who scored medium and high (≥ 14) on the Strengths and Difficulties Questionnaire (SDQ) in the PROMISE SB cohort N = (119/148; 80.4%). Another 29/148 (19.6%) were recruited from the PROMISE SB cohort as a comparator with low SDQ scores (< 14). Additionally, the open-ended questions in the diagnostic history were analysed. The MINI-KID comprised diagnostic questions on alcohol abuse and dependence, and descriptive data from the sub-study are presented in this paper.

RESULTS

A total of 11/148 (7.4%) children scored positive for alcohol abuse and dependence in this study, 10 of whom had high SDQ scores (≥ 14). The 10 children with SDQ-scores ≥ 14 had a variety of mental health comorbidities of which suicidality 3/10 (30.0%) and separation anxiety disorder 5/10 (50.0%) were the most common. The one child with an SDQ score below 14 did not have any comorbidities. Access to homemade brew, carer's knowledge of the drinking, and difficult household circumstances were issues expressed in the children's diagnostic histories.

CONCLUSIONS

The discovery of alcohol abuse and dependence among 5-8 year olds in clinical interviews from a community based trial cohort was unexpected, and we recommend continued research and increased awareness of these conditions in this age group.Trial registration Trial registration for PROMISE SB: Saving Brains in Uganda and Burkina Faso: Clinicaltrials.gov (NCT01882335), 20 June 2013.

Hereditary cataract in the Bengal cat in Poland

BACKGROUND

This paper reports the significant prevalence of a presumed hereditary cataract in the Bengal cat breed in Poland. The nuclear part of the lens is affected and previous reports from Sweden and France for this type of feline cataract suggest that a recessive mode of inheritance is probably involved.

RESULTS

Presumed congenital or neonatal cataract involving the posterior nuclear part of each lens was initially diagnosed in a 12 month old male Bengal cat. As both parents and a sibling were also affected with cataract, a group of 18 related and 11 non-related cats was then subsequently examined. Eight related cats and one non-related cat were found to be similarly affected. A breed survey was then completed using an additional five centres across Poland and a further 190 related cats were examined. A total of 223 cats have been involved in this study, with 75 (33%) being affected with several types of cataract and 67 (30%) being specifically affected with the same or similar nuclear lesions. Eight cats (3.6%) presented with other cataract types and a prominence of the posterior lens suture lines was recorded in 65 cats unaffected with cataract (29%). There were no demonstrable vision problems. Neither age nor coat colour was significantly associated with the nuclear cataract, but the nuclear cataract group had a higher proportion of females than the unaffected group. Pedigree analysis has indicated probable inheritance as a recessive trait.

CONCLUSIONS

These findings suggest that a presumably inherited nuclear cataract is present in the Bengal cat breed in Poland. It is considered to be either congenital or of very early onset, probably being inherited as a recessive trait. Although the lesion has no noticeable effect on vision, breeders in Poland and worldwide should be aware of the disease and clinical examination of young breeding stock prior to reproduction is advisable.
