Correlation of Programmed Death-Ligand 1 Expression With Lung Adenocarcinoma Histologic and Molecular Subgroups in Primary and Metastatic Sites

Programmed death-ligand 1 (PD-L1) expression in terms of the tumor proportion score (TPS) is the main predictive biomarker approved for immunotherapy against lung nonsmall cell carcinoma. Although some studies have explored the associations between histology and PD-L1 expression in pulmonary adenocarcinoma, they have been limited in sample size and/or extent of examined histologic variables, which may have resulted in conflicting information. In this observational retrospective study, we identified primary and metastatic lung adenocarcinoma cases in the span of 5 years and tabulated the detailed histopathologic features, including pathological stage, tumor growth pattern, tumor grade, lymphovascular and pleural invasion, molecular alterations, and the associated PD-L1 expression for each case. Statistical analyses were performed to detect associations between PD-L1 and these features. Among 1658 cases, 643 were primary tumor resections, 751 were primary tumor biopsies, and 264 were metastatic site biopsies or resections. Higher TPS significantly correlated with high-grade growth patterns, grade 3 tumors, higher T and N stage, presence of lymphovascular invasion, and presence of MET and TP53 alterations, whereas lower TPS correlated with lower-grade tumors and presence of EGFR alterations. There was no difference in PD-L1 expression in matched primary and metastases, although higher TPS was observed in metastatic tumors due to the presence of high-grade patterns in these specimens. TPS showed a strong association with a histologic pattern. Higher-grade tumors had higher TPS, which is also associated with more aggressive histologic features. Tumor grade should be kept in mind when selecting cases and blocks for PD-L1 testing.

Waldenström macroglobulinemia whole genome reveals prolonged germinal center activity and late copy number aberrations

The genomic landscape of Waldenström macroglobulinemia (WM) is characterized by somatic mutations in MYD88, present from the precursor stages. Using the comprehensive resolution of whole genome sequencing (WGS) in 14 CD19-selected primary WM samples; comparing clonal and subclonal mutations revealed that germinal center (GC) mutational signatures SBS9 (poly-eta) and SBS84 (AID) have sustained activity, suggesting that the interaction between WM and the GC continues over time. Expanding our cohort size with 33 targeted sequencing samples, we interrogated the WM copy number aberration (CNA) landscape and chronology. Of interest, CNA prevalence progressively increased in symptomatic WM and relapsed disease when compared with stable precursor stages, with stable precursors lacking genomic complexity. Two MYD88 wild-type WGS contained a clonal gain affecting chromosome 12, which is typically an early event in chronic lymphocytic leukemia. Molecular time analysis demonstrated that both chromosomal 12 gain events occurred early in cancer development whereas other CNA changes tend to occur later in the disease course and are often subclonal. In summary, WGS analysis in WM allows the demonstration of sustained GC activity over time and allows the reconstruction of the temporal evolution of specific genomic features. In addition, our data suggest that, although MYD88-mutations are central to WM clone establishment and can be observed in precursor disease, CNA may contribute to later phases, and may be used as a biomarker for progression risk from precursor conditions to symptomatic disease.

Cohort profile: the ESC EURObservational Research Programme Non-ST-segment elevation myocardial infraction (NSTEMI) Registry

AIMS

The European Society of Cardiology (ESC) EURObservational Research Programme (EORP) Non-ST-segment elevation myocardial infarction (NSTEMI) Registry aims to identify international patterns in NSTEMI management in clinical practice and outcomes against the 2015 ESC Guidelines for the management of acute coronary syndromes in patients presenting without ST-segment-elevation.

METHODS AND RESULTS

Consecutively hospitalised adult NSTEMI patients (n = 3620) were enrolled between 11 March 2019 and 6 March 2021, and individual patient data prospectively collected at 287 centres in 59 participating countries during a two-week enrolment period per centre. The registry collected data relating to baseline characteristics, major outcomes (in-hospital death, acute heart failure, cardiogenic shock, bleeding, stroke/transient ischaemic attack, and 30-day mortality) and guideline-recommended NSTEMI care interventions: electrocardiogram pre- or in-hospital, pre-hospitalization receipt of aspirin, echocardiography, coronary angiography, referral to cardiac rehabilitation, smoking cessation advice, dietary advice, and prescription on discharge of aspirin, P2Y12 inhibition, angiotensin converting enzyme inhibitor (ACEi)/angiotensin receptor blocker (ARB), beta-blocker, and statin.

CONCLUSION

The EORP NSTEMI Registry is an international, prospective registry of care and outcomes of patients treated for NSTEMI, which will provide unique insights into the contemporary management of hospitalised NSTEMI patients, compliance with ESC 2015 NSTEMI Guidelines, and identify potential barriers to optimal management of this common clinical presentation associated with significant morbidity and mortality.

The impact of COVID-19 on the quality of life of older adults: a cross-sectional study in Athens, Greece

Introduction

The COVID-19 has affected both physical and mental health of the elderly.

Objectives

The purpose of the present study was to estimate the impact of the second lockdown in Greece, on both quality of life and mental health in older people.

Methods

A cross sectional study was conducted among older adults who visited a primary care physician, from 1^st of March to April 30^th. An anonymous questionnaire was administered to collect basic sociodemographic data and implementation of hygiene precaution measures. The 5-item World Health Organization Well-Being Index (WHO-5) to measure well-being, the Generalized Anxiety Disorder Assessment (GAD-7) instrument was used to assess the anxiety levels and Geriatric Depression Scale (GDS-15) depressive symptoms of the responders, respectively. Statistical analysis was performed with SPSS v.24.0

Results

222 elderly took part in the study. 62.6% were female. According to the WHO-5, 37.4% present poor quality of life. GDS-15 reveals that 70.7% of the participants screened positive for moderate depression and 1.8% with severe symptoms. GAD-7 results estimated 32.9% of the participants to suffer from serious anxiety disorder and 37.4% from moderate. GAD-7 and GDS-15 were strongly associated (p <0.05) with female gender, low educational level and with comorbidities (coronary disease, diabetes mellitus and skeletomuscular diseases). Health precaution measures were negative correlated with mental health of the elderly. However, in participants with frequent contact with family and friends, lower anxiety levels were detected.

Conclusions

Our results highlight that older adult has experienced negative impact on both quality of life and mental health during 2^nd Covid-19 lockdown in Greece.

All that was missing from the students of the University of Patras and the return to a new daily life after quarantine

Introduction

The pandemic that broke out by the new coronavirus SARS-CoV-2 and the imposition of restrictive measures to reduce the dispersion, affects both the physical and mental health of all population groups.

Objectives

The main objective of the study was to investigate how these measures have impacted the students during the first quarantine period (Spring 2020). Also we wanted to know what they lacked most after the six-weeks-lockdown.

Methods

More than 2,000 students from all Schools of the University of Patras participated in the research, completing an online questionnaire. Emphasis was placed on the question “What is the FIRST thing you will do immediately after lifting the measures”. The open last option ‘Other’ was qualitative investigated with thematic analysis by gender.

Results

The answer options of the evaluated question were to ‘Go out for coffee/food/drink/fun with friends’ (58%) or ‘with family’ (5%), to ‘Visit beauty and hair salons’ (16%), to ‘Travel’ (6%), or to ‘Go shopping’ (2%). The option ‘Other’ was answered by 246 (13%) students. The thematic analysis revealed 13 categories, with first place ‘Restoring immediately social life without restrictions’, followed by ‘Seeing and being together with boyfriend/girlfriend’, but at the same time ‘Continue to be careful and take self-restraining measures after the end of the quarantine’.

Conclusions

Students of both genders lacked mainly social life and companionship. The need to return to a new daily routine with protection measures that limit both exposure to the new virus and the spontaneity, is obvious.

Bronchiolar Adenoma/Pulmonary Ciliated Muconodular Papillary Tumor

OBJECTIVES

To describe the histologic features that are helpful in the diagnosis of the rare bronchiolar adenomas/ciliated muconodular papillary tumors (BAs/CMPTs) during intraoperative consultation.

METHODS

Multi-institutional retrospective review of frozen sections of 18 BAs/CMPTs.

RESULTS

In 14 of 18 cases, BA/CMPT was the primary reason for sublobar lung resection, and in 4 cases, BA/CMPT was an incidental finding intraoperatively for resections performed for carcinoma in other lobes. There were 11 proximal-type/classic BAs/CMPTs and 7 distal-type/nonclassic BAs/CMPTs. Only 3 (16.7%) of 18 were correctly diagnosed at the time of frozen section, all of which were proximal type/classic. The remainder were diagnosed as adenocarcinoma (n = 7); invasive mucinous adenocarcinoma (n = 1); non-small cell lung carcinoma (n = 1); cystic mucinous neoplasm, favor adenocarcinoma (either mucinous or colloid type) (n = 1); favor adenocarcinoma, cannot exclude CMPT (n = 1); atypical proliferation (n = 2); mucinous epithelial proliferation (n = 1); and mucous gland adenoma (n = 1).

CONCLUSIONS

BA/CMPT can potentially be misdiagnosed as carcinoma during intraoperative consultation. On retrospective review of the frozen sections, the presence of the following may help to avoid misdiagnosis: a mixture of bland ciliated columnar cells, mucinous cells, and, most important, a basal cell layer, as well as a lack of necrosis, significant atypia, and mitoses.

COVID-19 lockdown and its impact on mental health in various population groups in Greece: A cross-sectional study

Introduction

COVID-19 pandemic and lockdown has brought a serious impact on physical and mental health.

Objectives

The purpose of the present study was to estimate the impact of the first lockdown in Greece, on both quality of life and anxiety levels in different occupational groups.

Methods

A cross-sectional on- line survey was conducted from 20^th of April to 4^th of May 2020. A 24-item anonymous questionnaire was administered to collect basic demographic and socioeconomic data. The 5-item WHO Well-Being Index (WHO-5, 0-100%, cut-off 52%) and the Generalized Anxiety Disorder Assessment (GAD-7) tools were used to assess well-being and anxiety, respectively. Statistical analysis was performed with SPSS for Windows v.24.0 Statistical Package.

Results

A total of 575 participated in the study, 62.8% females, 48.5% aged between 40 to 59 years. 32.5% were employed in education sector, 32.5% in health sector and 20.3% as season workers in tourism sector. Males showed slightly higher levels of wellbeing (52.1 vs. 47.3, p=0.023) and lower levels of anxiety (7.1 vs. 8.2, p=0.023) compared to females. Factors associated with higher wellbeing and lower anxiety were higher education and income level, optimism, taking less protection measures, and being seasonal worker. Furthermore, participants with comorbidities and symptoms like headache, musculoskeletal pain, as well as feeling depressed or stressed revealed lower wellbeing and higher anxiety scores.

Conclusions

Our study revealed an overall poor wellbeing and mild to moderate levels of anxiety during the lockdown. Actions should be taken to address and to prevent its serious impact on mental health.

Combined exercise programs as protective factor against depression later in life: A systematic review

Introduction

Exercise has been repeatedly reported as an effective means of preventing and treating mood disorders. Therefore, there is a significant research interest for the way exercise is connected with depression and the effectiveness of different exercise parameters as intensity, duration and modality. There is significant research evidence supporting the hypothesis that exercise can alleviate the symptoms of clinical depression. Nevertheless, there has not enough evidence to compare the effectiveness of deferent types of exercise as complementary therapy in depression.

Objectives

The purpose of the present study was to review the available research concerning the effect of exercise modality in depression and attempt to code and analyze the programs used in elderly (>65).

Methods

A systematic review was contacted of randomized control trials published in electronic journals. The electronic data bases PubMed, EBSCOhost and Trip Medical Database were used.

Results

Combined programs are predominate used for improving mood in elderly and the combinations used more frequently was short-term, light to moderate sub maximal aerobic exercise combined with dynamic resistance exercise following by Short-term, light to moderate sub maximal aerobic exercise combined with static exercise. Other psychosocial factors that commonly included in the combined exercise programs are group interaction, mindfulness and music.

Conclusions

Combined exercise programs are as effective as simple programs in alleviated the symptoms of depression in elderly. Their advantages over simple programs are that they can promote other health benefits; they are less time consuming and more pleasurable to participants. Therefore, they are good exercise choice for elderly.

Anxiety and depression among students in a greek university amidst COVID-19 pandemic

Introduction

The coronavirus pandemic has challenged the world with an unprecedented situation. Social distancing, self or quarantine isolation, personal hand hygiene, self-protection, and the fear of becoming infected with the virus, come with a psychological fallout. The COVID-19 pandemic has affected students around the world, in terms of their education and lifestyle.

Objectives

To investigate the impact of COVID-19 pandemic on the students’ mental health and well-being at the University of Patras, in Western Greece.

Methods

An online questionnaire was prepared to collect responses from students during April 2020. Socio-demographic data, academic status, opinions about distance learning, changes in daily routine during the lockdown and anxiety and depression scores, according to the Greek version of the Hospital Anxiety and Depression Scale (HADS), were gathered.

Results

The total number of responders was 2009, of which 67.3% women. During lockdown, the 68% of the students returned to their family home. Anxiety and depression scores were higher in students with a low income, poor self-rated health, not informed about COVID-19, not satisfied with distance learning and being annoyed at staying home. Prevalence of anxiety and depression was found to be 35.8% and 51.2%, ranging from 26.7% to 48.2% for anxiety and from 36.3% to 60.5% for depression in Health Sciences and Humanities and Social Sciences, respectively.

Conclusions

Depression rates among university students in Greece were alarmingly high, denoting the impact of lockdown and changes in students’ life, due to the COVID-19 pandemic.

Postpartum Depression in a Public Hospital in Cyprus. Prevalence, Risk Factors

Introduction

Postpartum depression (PPD) is a serious mental health condition. Untreated PPD places the mother and infant at risk and is associated with significant long-term effects on child development and behavior.

Objectives

Appropriate screening for and prompt recognition and treatment of depression after the birth of a child are essential for maternal and child well-being.

Aims

The purpose of the present study was to estimate the prevalence of PPD in the first 5 days after the birth of a neonate and to investigate associations with several risk factors.

Methods

A cross-sectional study was conducted among 150 mothers, in a public obstetric hospital in Nicosia, Cyprus. A questionnaire was administered including socio-demographic characteristics. The Greek version of the Edinburgh postnatal depression scale (EPDS), a 10–item questionnaire to identifying women who are at risk of PPD, was used to estimate depression among the participants.

Results

According to EPDS, 42% of the mothers screened positive for risk of developing PPD. Higher risk was observed in very young mothers (<20 years) (66.6% vs 15%), in women with history of psychological disorders (86.95% vs 33.85%), in single mothers (71.69% vs 22.8%), in women with serious problems during the pregnancy (74% vs 23.95%) and in mothers with not healthy neonate (75.7% vs 32.4%).

Conclusion

The study reveals a high prevalence of PPD and identifies various risk factors associated with developing PPD. The use of maternal depression screening programs such as the EPDS may help to recognize an elevated risk of postpartum depression and to ensure a healthier mother-child relationship.

Future therapeutic options for patients with Waldenström macroglobulinemia

Waldenström macroglobulinemia (WM) is a rare lymphoma characterized by the accumulation of IgM-producing lymphoplasmacytic cells. Although WM patients can experience prolonged remissions, the disease invariably recurs. Therefore, novel treatments associated with higher success rates and lower toxicity profiles are needed. The discovery of recurrent mutations in the MYD88 and CXCR4 genes has unraveled potential therapeutic targets in WM patients. As a result of these findings and based on the design and execution of a prospective clinical trial, the FDA granted approval to ibrutinib, an oral Bruton tyrosine kinase (BTK) inhibitor, to treat patients with symptomatic WM. The present review focuses on potential therapies that could change the landscape of treatment of patients with WM, specifically focusing on inhibitors or antagonists or the proteasome, BTK, CD38, BCL2 and the CXCR4 and MYD88 genes themselves. Novel agents with novel mechanisms of action should be evaluated in the context of carefully designed clinical trials.

Clonal architecture of CXCR4 WHIM-like mutations in Waldenström Macroglobulinaemia

CXCR4(WHIM) somatic mutations are distinctive to Waldenström Macroglobulinaemia (WM), and impact disease presentation and treatment outcome. The clonal architecture of CXCR4(WHIM) mutations remains to be delineated. We developed highly sensitive allele-specific polymerase chain reaction (AS-PCR) assays for detecting the most common CXCR4(WHIM) mutations (CXCR4(S338X C>A and C>G) ) in WM. The AS-PCR assays detected CXCR4(S338X) mutations in WM and IgM monoclonal gammopathy of unknown significance (MGUS) patients not revealed by Sanger sequencing. By combined AS-PCR and Sanger sequencing, CXCR4(WHIM) mutations were identified in 44/102 (43%), 21/62 (34%), 2/12 (17%) and 1/20 (5%) untreated WM, previously treated WM, IgM MGUS and marginal zone lymphoma patients, respectively, but no chronic lymphocytic leukaemia, multiple myeloma, non-IgM MGUS patients or healthy donors. Cancer cell fraction analysis in WM and IgM MGUS patients showed CXCR4(S338X) mutations were primarily subclonal, with highly variable clonal distribution (median 35·1%, range 1·2-97·5%). Combined AS-PCR and Sanger sequencing revealed multiple CXCR4(WHIM) mutations in many individual WM patients, including homozygous and compound heterozygous mutations validated by deep RNA sequencing. The findings show that CXCR4(WHIM) mutations are more common in WM than previously revealed, and are primarily subclonal, supporting their acquisition after MYD88(L265P) in WM oncogenesis. The presence of multiple CXCR4(WHIM) mutations within individual WM patients may be indicative of targeted CXCR4 genomic instability.

[Prevalence of depression among the elderly]

Depression is the most common mental health problem among older people, posing a critical impact on their well-being and the quality of life. The objective of the present study was to estimate the prevalence of depression in elderly population of an urban area and to investigate the association with various aggravating or protective factors. The sample consisted of 239 subjects, aged >60 years, members of "daycare centers for older people" (KAPI) in the municipality of Patras, W-Greece. A questionnaire was developed to collect basic demographic and socioeconomic data, including three questions from the "European Health Interview Survey" (EHIS), regarding self-reported and/or by a physician diagnosed depression. Moreover, to all participants the Greek validated version of the Geriatric Depression Scale (GDS-15) was applied, to screen the elderly for depressive symptoms. The scores of the GDS were a) compared to the corresponding answers of the EHIS questions and b) associated to the various recorded basic parameters. Statistical analyses were performed using the SPSS v. 17.0. The results of the GDS indicated 45% of the studied population having depressive symptoms (36% moderate, 9% severe), while having ever been affected with chronic depression reported 49 (20.5%) and out of them 34 (66.8%) stated to have been diagnosed by a medical doctor. In detail, out of the 162 (67.8%) subjects reporting never have been affected by a depression, 37 (22.8%) and 8 (4.9%) screened positive for moderate and severe depressive symptoms, respectively. In 27 individuals who reported not to know if they have depression, 16 revealed depressive symptoms using the GDS. Depressive symptoms were more frequent in women (54.6% vs 37.4%, p=0.027), in not married, including divorced and widowed, compared to married (55.6% vs 38.9%, p=0.038) and in subjects living alone at home (62% vs 38.1%, p=0.003). Depressive symptoms were more frequent in elderly with chronic diseases compared to elderly without comorbidity (50.8% vs 27.5%, p=0.02). High prevalence of depressive symptoms in elderly population is evident, but rarely recognized. The systematic use of short GDS versions in Primary Care may increase detection rates of depression among the elderly.
