Comparing clinical features of young onset, middle onset and late onset Parkinson's disease

BACKGROUND

Parkinson's disease (PD) affects 1-2% of the population over 65 years. There is evidence that the clinical features differ with age at symptom onset, but published information is scarce.

METHODS

We reviewed the charts of 593 PD patients and divided them into young onset (≤49 years), middle onset (50-69 years) and late onset (≥70 years) groups. Data collected included age at symptom onset, year of onset, family history of Parkinson's disease in first and second degree relatives, predominant first symptom, first anti parkinsonian medication prescribed, frequency of levodopa-induced dyskinesia, therapy related dystonia, therapy related gastrointestinal side effects, hallucination, dementia, depression and apathy.

RESULTS

The middle onset was the largest group (51%), followed by the late onset (39%) and the young onset (10%) groups. Young onset patients had a more frequent family history of Parkinson's disease and a longer survival. Symptoms other than tremor were more frequent as the initial symptom of the young onset group, and the frequency of tremor as the first symptom increased with advancing age at onset. Depression was more frequent in the young onset group. The frequency of treatment related dyskinesia or dystonia decreased with advancing age at onset.

CONCLUSION

We have identified specific clinical differences in Parkinson's disease related to the patient's age at onset and added to the existing knowledge of the variability of disease presentation. We suggest an age of onset of 49 years or less for the definition of young onset PD.

Sex and age interact to determine clinicopathologic differences in Alzheimer's disease

Women reportedly make up two-thirds of Alzheimer’s disease (AD) dementia sufferers. Many estimates regarding AD, however, are based on clinical series lacking autopsy confirmation. The Florida Autopsied Multi-Ethnic (FLAME) cohort was queried for AD cases with a total of 1625 identified ranging in age from 53 to 102 years at death. Standard neuropathologic procedures were employed and clinical information was retrospectively collected. Clinicopathologic and genetic data (MAPT and APOE) were stratified by sex. Within the neuropathologically diagnosed AD cohort, the overall number of women and men did not differ. Men were younger at onset of cognitive symptoms, had a shorter disease duration, and more often had atypical (non-amnestic) clinical presentations. The frequency of autopsy-confirmed AD among women and men stratified by age at death revealed an inverse U-shaped curve in men and a U-shaped curve in women, with both curves having inflections at approximately 70 years of age. Regional counts of neurofibrillary tangles differed in women and men, especially when examined by age intervals. Women had overall greater severity of neurofibrillary tangle counts compared to men, especially in the hippocampus. Men were more often classified as hippocampal sparing AD, whereas limbic predominant AD was more common in women. Men and women did not differ in frequency of MAPT haplotype or APOE genotype. Atypical clinical presentations, younger age at onset and shorter disease duration were more frequent in men, suggesting that the lower reported frequency of AD in men may be due to more frequent atypical clinical presentations not recognized as AD. Our data suggest that neuropathologically diagnosed AD cases have the same frequency of women and men, but their clinical presentations and ages at onset tend to differ.

Breast cancer survival among young women: a review of the role of modifiable lifestyle factors

Almost 7 % of breast cancers are diagnosed among women age 40 years and younger in Western populations. Clinical outcomes among young women are worse. Early age-of-onset increases the risk of contralateral breast cancer, local and distant recurrence, and subsequent mortality. Breast cancers in young women (BCYW) are more likely to present with triple-negative (TNBC), TP53-positive, and HER-2 over-expressing tumors than among older women. However, despite these known differences in breast cancer outcomes and tumor subtypes, there is limited understanding of the basic biology, epidemiology, and optimal therapeutic strategies for BCYW. Several modifiable lifestyle factors associated with reduced risk of developing breast cancer have also been implicated in improved prognosis among breast cancer survivors of all ages. Given the treatment-related toxicities and the extended window for late effects, long-term lifestyle modifications potentially offer significant benefits to BCYW. In this review, we propose a model identifying three main areas of lifestyle factors (energy imbalance, inflammation, and dietary nutrient adequacy) that may influence survival in BCYW. In addition, we provide a summary of mechanisms of action and a synthesis of previous research on each of these topics.

Incidence of complications in young-onset diabetes: Comparing type 2 with type 1 (the young diab study)

BACKGROUND

There is little data on the incidence of diabetes complications in young onset type 1 diabetes (T1DM) and type 2 diabetes (T2DM) in non European populations.

METHODS

From a tertiary diabetes centre, Chennai, India, we recruited 108 T1DM (defined by abrupt onset of symptoms or diabetic ketoacidosis, absent insulin reserve requiring insulin treatment) and 90 T2DM participants (defined by absence of ketosis, good beta-cell reserve, and good response to oral agents) who were diagnosed between the ages of 10 and 25years, and without any evidence of diabetes complications at diagnosis. We estimated the incidence of various complications (median follow up of five years); retinopathy was defined by presence of at least one definite microaneurysm by retinal photography, nephropathy by urinary albumin excretion ⩾30μg/mg of creatinine, neuropathy by vibration perception threshold ⩾20V on biothesiometry, peripheral vascular disease by an ankle-brachial index <0.9, and ischemic heart disease (IHD) by history of myocardial infarction or coronary revascularization or Q waves on ECG or on drug treatment for IHD.

RESULTS

The mean ages at diagnosis of T1DM and T2DM participants were 17.1±4.2vs. 21.6±3.6years respectively. The incidence of various complications reported in numbers/1000 person years of follow up of T1DM and T2DM were: retinopathy 77.4vs. 78.0/1000 person years, nephropathy, 62.0vs. 58.8, neuropathy 7.8 vs. 13.9 and ischemic heart disease 1.2vs. 5.4. In Cox regression analysis, after adjustment for age, glycated hemoglobin, systolic blood pressure and serum cholesterol, T2DM participants had 2.11 times (95%CI: 1.27-3.51) higher risk of developing any diabetes complication, compared to T1DM.

CONCLUSIONS

Young-onset T2DM have a more aggressive disease course than T1DM.

Immune cell profiles in the tumor microenvironment of early-onset, intermediate-onset, and later-onset colorectal cancer

BACKGROUND

Despite heightened interest in early-onset colorectal cancer (CRC) diagnosed before age 50, little is known on immune cell profiles of early-onset CRC. It also remains to be studied whether CRCs diagnosed at or shortly after age 50 are similar to early-onset CRC. We therefore hypothesized that immune cell infiltrates in CRC tissue might show differential heterogeneity patterns between three age groups (< 50 "early onset," 50-54 "intermediate onset,"  ≥ 55 "later onset").

METHODS

We examined 1,518 incident CRC cases with available tissue data, including 35 early-onset and 73 intermediate-onset cases. To identify immune cells in tumor intraepithelial and stromal areas, we developed three multiplexed immunofluorescence assays combined with digital image analyses and machine learning algorithms, with the following markers: (1) CD3, CD4, CD8, CD45RO (PTPRC), and FOXP3 for T cells; (2) CD68, CD86, IRF5, MAF, and MRC1 (CD206) for macrophages; and (3) ARG1, CD14, CD15, CD33, and HLA-DR for myeloid cells.

RESULTS

Although no comparisons between age groups showed statistically significant differences at the stringent two-sided α level of 0.005, compared to later-onset CRC, early-onset CRC tended to show lower levels of tumor-infiltrating lymphocytes (P = 0.013), intratumoral periglandular reaction (P = 0.025), and peritumoral lymphocytic reaction (P = 0.044). Compared to later-onset CRC, intermediate-onset CRC tended to show lower densities of overall macrophages (P = 0.050), M1-like macrophages (P = 0.062), CD14+HLA-DR+ cells (P = 0.015), and CD3+CD4+FOXP3+ cells (P = 0.039).

CONCLUSIONS

This hypothesis-generating study suggests possible differences in histopathologic lymphocytic reaction patterns, macrophages, and regulatory T cells in the tumor microenvironment by age at diagnosis.

Impact of age at diagnosis of head and neck cancer on incidence of metachronous cancer

Background

Metachronous cancer in patients with head and neck cancer (HNC) is common and is associated with a poor prognosis. We aimed to evaluate the incidence of metachronous cancer at different sites according to age at diagnosis of index HNC.

Methods

We collected data on 2011 patients with oral cancer, oropharynx cancer, hypopharyngeal cancer, and laryngeal cancer as index cancers using the Osaka International Cancer Institute Cancer Registry database between 2005 and 2016. Among these, we analyzed 1953 patients after excluding 5 patients who were not followed-up and 53 patients with simultaneous multiple index cancers. We evaluated the cumulative incidence of metachronous cancer in the esophagus, lung, and other sites according to age at diagnosis of the index HNC using the Kaplan–Meier method. Multivariate logistic regression analysis was performed to identify factors that influenced the incidence of metachronous cancers following HNC.

Results

The cumulative incidence of metachronous esophageal cancer in young patients (< 65 years) was significantly higher than that in old patients (≥ 65 years) (12.1% vs 8.5% at 5 years, and 16.5% vs 11.2% at 10 years; p = 0.015). On the other hand, the cumulative incidence of the other cancers in young patients was significantly lower than that in old patients (7.8% vs 12.2% at 5 years, and 13.9% vs 15.3% at 10 years; p = 0.017). The cumulative incidence of lung cancer was not significance according to age at diagnosis of the index HNC. In the multivariate analysis, histological type (squamous cell carcinoma) and lesion location (hypopharynx and larynx) were independently associated with metachronous cancers. Moreover, age at diagnosis of the index HNC (< 65 years), histological type (squamous cell carcinoma) and lesion location (hypopharynx) were significant predictors of metachronous esophageal cancer incidence and lesion location (hypopharynx) was a significant predictor of metachronous lung cancer incidence.

Conclusion

Risk stratification of metachronous cancers with age and other predictors may help to properly manage patients with HNC.

Trial registration

The present study is a non-intervention trial.

Musculoskeletal manifestations occur predominantly in patients with later-onset familial Mediterranean fever: Data from a multicenter, prospective national cohort study in Japan

Background

We showed previously that Japanese individuals with familial Mediterranean fever (FMF) have a more atypical phenotype compared to endemic areas. The clinical differences between young-onset FMF (YOFMF), adult-onset FMF (AOFMF), and late-onset FMF (LOFMF) in Japan are unclear.

Methods

We enrolled 395 consecutive patients. We defined YOFMF, AOFMF, and LOFMF as the onset of FMF at < 20, 20–39, and ≥ 40 years of age, respectively. We compared clinical manifestations and MEFV mutations patterns among these groups.

Results

Median ages at onset were YOFMF 12.5 years (n = 182), AOFMF 28 years (n = 115), and LOFMF 51 years (n = 90). A family history, MEFV mutations in exon 10, and more than two MEFV mutations were significantly more frequent in the earlier-onset groups (p < 0.01, p < 0.0001, and p < 0.001, respectively). In the accompanying manifestations, thoracic and abdominal pain were significantly more frequent in the earlier-onset groups (p < 0.01 and p < 0.0001, respectively), whereas arthritis and myalgia were significantly more frequent in the later-onset groups (p < 0.0001 and p < 0.01, respectively). The multiple logistic regression analysis revealed that the presence of MEFV exon 10 mutations and earlier onset were significantly associated with serositis, whereas the absence of MEFV exon 10 mutations, later onset, and the presence of erysipelas-like erythema were significantly associated with musculoskeletal manifestations. There was no significant between-group difference in the responsiveness to colchicine.

Conclusions

Our results indicate that the later-onset FMF patients had a lower percentage of MEFV mutations in exon 10 and predominantly presented arthritis and myalgia. It is important to distinguish their FMF from other inflammatory diseases.

Identification of mutations in the PARK2 gene in Serbian patients with Parkinson's disease

Mutations in the PARK2 (PRKN) gene are the most common cause of autosomal-recessive (AR) juvenile parkinsonism and young-onset Parkinson's disease (YOPD). >100 different variants have been reported, including point mutations, small indels and single or multiple exon copy number variations. Mutation screening of PARK2 was performed in 225 Serbian PD patients (143 males and 82 females) with disease onset before 50 years and/or positive family history with apparent AR inheritance. All coding regions and their flanking intronic sequences were amplified and directly sequenced. Whole exon multiplications or deletions were detected using Multiple Ligation Probe Amplification (MLPA) method. We identified 12 PD patients with PARK2 mutations (5.3%). Five patients (2.2%) had biallelic mutations and seven (3.1%) were single mutation carriers. Patients with compound heterozygous mutations had earlier onset of the disease compared to non-carriers (p = 0.005) or heterozygotes (p = 0.001). Other clinical features in mutation carriers were not different compared to non-carriers. In our cohort, sequence and dosage variants were equally represented in patients, inducing their first symptoms mainly before the age of 30. For efficient genetic testing strategy, patients with early, especially juvenile onset of PD were strong candidates for both dosage and sequence variants screening of PARK2 gene.

Supporting people with young onset dementia and their families: An evaluation of a training course for care workers

This article reports the findings of an evaluation of a training course for care workers who care for people with dementia in the community. Twenty-four care workers participated in the training which took place in London and Surrey, United Kingdom. The training had a significant positive impact on participants' confidence in understanding the experiences and social care needs of people with young onset dementia (YOD) and their families. Participants also perceived that the training would help them improve their working practice by furthering their understanding of practical approaches to supporting and caring for people with dementia in general. Additionally, participants reported many ways in which they perceived being able to specifically support and empower people with YOD. It was concluded that the short training course improved knowledge and confidence for care workers on dementia care, and specifically in understanding how to support people with YOD and their families. Dementia specific training should be considered by service managers as a way of potentially increasing care worker job satisfaction.

Relative increase in cerebellar gray matter in young onset essential tremor: Evidence from voxel-based morphometry analysis

This study is to investigate the presence of brain gray matter abnormalities in young onset essential tremor (ET) patients with arm tremor. Thirty ET patients together with 30 healthy volunteers were taken as candidates. Magnetic resonance imaging (MRI) was performed and voxel-based morphometry was used to compare gray matter density between the patients and volunteers. Washington Heights-Inwood Genetic Study of Essential Tremor (WHIGET) rating scale was applied to assess tremor severity in the patients. Eventually Twenty-Seven ET patients and Twenty-Seven volunteers were enrolled in the study. Voxel-based morphometry showed significant expansion of the bilateral cerebellum, occipital fusiform cortices, right inferior temporal gyrus, and precentral lobes (P < 0.05, TFCE corrected). Decrease in gray matter was detected only in the left parietal lobe. Region of interest analysis showed volume enlargement in thalamus, midbrain, and precuneus (P < 0.05, TFCE corrected). Importantly, significant negative correlation was found between the lateralized index of cerebellum and the tremor score which might implicate that the altered rightward lateralization in the cerebellum is possibly a response of the tremor effects in ET patients. Cerebellar gray matter expansion in young onset ET patients with arm tremor might be the result of compensation towards decline of cerebellar function.

Young-onset trigeminal neuralgia: a clinical study and literature review

OBJECTIVE

Trigeminal neuralgia (TN) primarily occurs in elderly adults and is thought to be induced by neurovascular compression. However, a few children and young adults may present with the clinical features of TN. In this study, we aim to retrospectively assess the data of young patients with TN from a single center.

METHODS

Of 783 consecutive patients with TN treated at our center between 2007 and 2017, 11 young patients under the age of 30 years with TN met the inclusion criteria and were enrolled. Their clinical records, surgical treatments, and long-term outcomes were obtained and analyzed.

RESULTS

All the 11 patients with TN underwent microvascular decompression (MVD). The average age at symptom onset was 24 years (range, 14-29 years), and the average age at the time of surgery was 28.9 years (range, 25-35 years). Further, 5 patients had left-sided symptoms, and 6 had right-sided symptoms. Surgery revealed only venous compression in 3 patients, only arterial compression in 5 patients, and both venous and arterial compression in 3 patients. The average duration of symptoms was 4.9 years, and the average follow-up duration was 7.4 years (range, 4.5-12.9 years). The long-term outcome was excellent in 9 patients and good in 2 patients, and there were no long-term complications.

CONCLUSIONS

The symptoms and surgical findings presented in this cohort for young-onset TN are similar to those reported in elderly adults. MVD appears to be a safe and effective treatment for young patients with TN.

Young-Onset Dementia with Lewy Bodies

Young-onset (< 65 years) dementia is a challenging clinical problem. A 61-year-old man visited our clinic because of a 2-year history of mild cognitive impairment of the executive disorder type. He was initially suspected of having young-onset Alzheimer's disease due to the lack of motor signs or hippocampal atrophy by conventional brain MRI. However, he proved to have anosmia, erectile dysfunction, hypersexuality, constipation, REM sleep behavior disorder, and emotional lability; imaging findings included positive brain perfusion SPECT, nigrosome MRI, DAT scan, and MIBG myocardial scintigraphy. All these clinical imaging features led to the correct diagnosis of young-onset dementia with Lewy bodies (YOD-DLB). It is hoped that this case report will help facilitate a future prospective study to diagnose and follow YOD-DLB patients with the aim of determining appropriate management and care.

Latamoxef-induced severe thrombocytopenia during the treatment of pulmonary infection: A case report

BACKGROUND

Latamoxef shows excellent antibacterial activity against anaerobic bacteria such as Bacteroides fragilis. Reports of thrombocytopenic toxicity of latamoxef are limited. This report presents a case of severe thrombocytopenia possibly induced by latamoxef, an infrequent adverse drug reaction in a young patient with tuberculosis and Crohn's disease in China.

CASE SUMMARY

We reported a case of severe thrombocytopenia induced by latamoxef in a 28-year-old man with tuberculosis and Crohn's disease. On admission, the patient presented with a cough productive of bloody sputum, a chest computed tomogram suggested scattered mottled, high-density shadows in both lungs. Laboratory tests indicated a platelet count of 140000/μL. Considered a pulmonary bacterial infection, the patient received anti-infection therapy with latamoxef (dose: 2.0 g) intravenously Q12h. On the 9^th day of treatment, the platelet count decreased to 44000/μL. On the 12^th day, scattered purpura and ecchymosis appeared on the patient’s limbs and trunk, and the platelet count decreased to 9000/μL after latamoxef treatment for 15 d. Three days after discontinuation of latamoxef, the platelet count recovered to 157000/μL, and the area of scattered purpura and ecchymosis on the limbs and trunk decreased. The platelet counts remained in the normal range, and no thrombocytopenia was found at follow-up 15 mo after discharge.

CONCLUSION

For patients treated with latamoxef, platelet counts should be carefully followed, and caregivers should be vigilant for the appearance of scattered ecchymosis.

Familial hemifacial spasm of young-onset: Report of two cases

Hemifacial spasm (HFS) is defined as an involuntary twitching of the hemifacial muscles supplied by the facial nerve. It is mostly attributed to a vascular compression with the facial nerve. Familial HFS has been described in less than 10% of cases of sporadic HFS and usually develops after the age of 40. Young-onset HFS is a rare condition, generally presenting prior to the age of 30 with an estimated prevalence of 6.5% of sporadic HFS. No familial component has been described in small series of young-onset HFS. Here we report the cases of a patient and his mother who both developed right HFS in their early twenties. Both patients had a neurovascular contact between their right facial nerve and a branch of their right posterior inferior cerebellar artery. Our report explores how young-onset familial HFS may be the consequence of hereditary vascular variations.

Global burden of young-onset gastric cancer: a systematic trend analysis of the global burden of disease study 2019

BACKGROUND

While gastric cancer is generally declining globally, the temporal trend of young-onset (< 40 years) gastric cancer remains uncertain. We performed this analysis to determine the temporal trends of young-onset gastric cancer compared to late-onset cancer (≥ 40 years).

METHODS

We extracted cross-sectional data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019. The burden of gastric cancer from 1990 to 2019 was assessed through indicators including incidence and mortality rates, which were classified at global, national, and regional levels, and according to socio-demographic indexes (SDI) and age or sex groups. Joinpoint regression analysis was used to identify specific years with significant changes. The correlation between AAPC with countries' average SDI was tested by Pearson's Test.

RESULTS

The global incidence rate of young-onset gastric cancer decreased from 2.20 (per 100,000) in 1990 to 1.65 in 2019 (AAPC: - 0.95; 95% confidence interval [CI] - 1.25 to - 0.65; P < 0.001). Late-onset cancer incidence also decreased from 59.53 (per 100,000) in 1990 to 41.26 in 2019 (AAPC: - 1.23; 95% CI - 1.39 to - 1.06, P < 0.001). Despite an overall decreasing trend, the incidence rate of young-onset cancer demonstrated a significant increase from 2015 to 2019 (annual percentage change [APC]: 1.39; 95% CI 0.06 to 2.74; P = 0.041), whereas no upward trend was observed in late-onset cancer. Mortality rates of young- and late-onset cancer both exhibited a significant decline during this period (AAPC: - 1.82; 95% CI - 2.15 to - 1.56; P < 0.001 and AAPC: - 1.69, 95% CI - 1.79 to - 1.59; P < 0.001). The male-to-female rate ratio for incidence and mortality in both age groups have been increasing since 1990. While countries with high SDI have had a greater decline in the incidence of late-onset gastric cancer (slope of AAPC change: - 0.20, P = 0.004), it was not observed in young-onset cancer (slope of AAPC change: - 0.11, P = 0.13).

CONCLUSIONS

The global incidence and mortality rates of both young- and late-onset gastric cancer have decreased since 1990. However, the incidence rate of young-onset cancer has demonstrated a small but significant upward trend since 2015. There was disparity in the decline in young-onset gastric cancer among male and high SDI countries. These findings could help to inform future strategies in preventing gastric cancer in younger individuals.

Atrial fibrillation in young hospitalized patients: Clinical characteristics, predictors of new onset, and outcomes

BACKGROUND

Atrial fibrillation (AF) in young adults is an uncommon and not well studied entity.

METHODS

Consecutive patients aged 18-45 years admitted to internal or cardiology services in a large tertiary medical center (January 1, 2009 through December 31, 2019) were included. Clinical, electrocardiographic, and echocardiographic data were compared between patients with and without AF at baseline. Predictors of new-onset AF in the young were identified using multivariate Cox regression model among patients free of baseline AF.

RESULTS

Final cohort included 16,432 patients with median age of 34 (IQR 26-41) years of whom 8914 (56 %) were men. Patients with AF at baseline (N = 366; 2 %) were older, more likely to be men, and had higher proportion of comorbidities and electrocardiographic conduction disorders. Male sex, increased age, obesity, heart failure, congenital heart disease (CHD) and the presence of left or right bundle branch block were all independently associated with baseline AF in a multivariate model (p < 0.001 for all). Sub-analysis of 10,691 (98 %) patients free of baseline AF identified 85 cases of new-onset AF during a median follow up of 3.5 (IQR 1.5-6.5) years. Multivariate model identified increased age, heart failure, and CHD as independent predictors of new-onset AF. Finally, the CHARGE-AF risk score outperformed the CHA2DS2-VASc score in AF prediction [AUC of ROC 0.75 (0.7-0.8) vs. 0.56 (0.48-0.65)].

CONCLUSIONS

AF among hospitalized young adults is not rare. Screening for new-onset AF in young post hospitalization patients may be guided by specific clinical predictors and the CHARGE-AF risk score.

Gender differences in the young-onset persistent delusional disorder

We conducted a retrospective chart review to examine the gender differences in young onset Persistent Delusional Disorder (PDD) subjects (N = 236) with onset of illness before the age of 30 years. Gender differences in marital and employment status were significant (p-0.001). Delusion of infidelity and erotomania were more common in females, while males had more body dysmorphic and persecutory delusions (X²-20.45, p-0.009). Males had more substance dependence (X²-21.31, p < 0.001), as well as a family history of substance abuse and PDD (X²-18.5, p < 0.01). To conclude, gender differences in PDD comprised some psychopathology, co-morbidity, and family history among those with young onset PDD.

Cohort prevalence of young-onset type 2 diabetes in South Asia: A systematic review

BACKGROUND & AIM

The prevalence of young onset (≤30 years) type 2 diabetes (T2D) is increasing in South Asians, reflecting rise in childhood obesity. This systematic review analyses current data on thecohort prevalence of young onset T2D in South Asians.

METHODS

PubMed, Scopus,Science Direct,and Ebscohost were searched for articles published between 1990 and 2024, anda manual search identified additional articles. This study included case series, cross-sectional, retrospective cohort, or case reports.

RESULTS

Out of 5073 studies, 26 eligible studies were found including three case reports. Seventeen studies were from India, five werefrom other South Asian countries (Pakistan, Bangladesh, Nepal, Maldives), and nine were on migrant South Asians residing in different countries (UK,USA,Qatar, Canada). The cohort prevalence of young onset T2D in South Asians ranged from 0.1 % to 28.3 % (India 0.4 to 26.8 %, other SA countries 0.1 to 28.3 %, and migrant South Asians 4.1 to 18.1 %).

CONCLUSION

The burden of T2D among native South Asian children and young adults is higher than among migrant South Asians. This contrasts with traditional perceptions that T2D primarily affects older individuals and the South Asian diaspora i.e., those who have migrated from South Asia.

Microvascular decompression for young onset primary trigeminal neuralgia: a single-center experience

This study aims to explore the causes of primary young onset trigeminal neuralgia (TN) and the clinical outcomes of these patients. From May 2015 to December 2020, 19 primary TN patients with onset age under 30 years underwent microvascular decompression (MVD) in Nanjing Drum Tower Hospital. In this study, the clinical characteristics, surgical outcomes, and postoperative complications of these patients were analyzed retrospectively. Of the 19 patients, 5 were males and 14 were females, and the pain was located on the right side in 10 cases (52.6%). Vascular compression was observed in 17 patients, including 14 cases of superior cerebellar artery (SCA) alone, 2 cases of superior petrosal vein (SPV) alone, and 1 case of SCA and SPV combined. Two patients had no neurovascular conflict, and nerve combing was performed. After surgery, 18 patients got immediate pain relief; 1 patient improved but still had occasional pain. With a mean follow-up of 42.7 ± 22.3 months, one patient was found to have a relapse 45 months after MVD. Surgical complications including mild facial numbness in two patients and hearing impairment in one patient. Neurovascular compression is the main cause of young onset primary TN, and the most commonly encountered vascular was SCA. MVD is a safe and effective treatment for these patients.

Holding Multiple Identities: a Personal Narrative of Young Onset Colorectal Cancer

This is a personal narrative of my experience as a young man diagnosed with colorectal cancer. It is an exploration of the tension between multiple identities, including a clinical nurse specialist, academic and oncology patient. Young patients with colorectal cancer face particular challenges. They are often diagnosed with more advanced and poorly differentiated cancers. Research around young onset colorectal cancer is controversial, with some studies suggesting poorer survival. Although there is research in this area, there are few qualitative accounts that describe raw, honest and diverse narratives of colorectal cancer experiences, especially in young people. Writing personal narratives is a powerful experience, it has allowed me to tell my story to the world and given me time to reflect and make sense of my new reality. Although this journey has forced me to let go of my old identity, and embrace a new and challenging existence, the truth is that being diagnosed with cancer stinks. Writing this narrative is an uncomfortable process, punctuated with truths that are difficult to speak. However, sharing my story has provided a platform for self-exploration, a safe space to narrate my experience with cancer in the hope that it helps other clinicians, researchers and patients.
