Development, validation, and accuracy of ORCHESTRA emotional exhaustion screening questionnaire among healthcare workers during COVID-19 Pandemic

BACKGROUND

The COVID-19 pandemic has posed unprecedented challenges, particularly for healthcare workers (HCWs). The prolonged struggles exposed the HCWs to a variety of stressors, potentially leading to burnout. Emotional exhaustion is widely recognized as the core component of burnout. This research aims to conceptualize and develop an emotional exhaustion screening questionnaire through literature review, validation, and accuracy testing.

METHOD

A literature review of questionnaires and extraction of items on emotional exhaustion were performed in June 2022. We proceed with the face validity of the items by experts. The items with good content validity ratio and index were selected and reworded to suit the context of HCWs working during the COVID-19 pandemic. A pilot test of the questionnaire was done in the Central University Hospital of Asturias (HUCA) from October to December 2022 with a sample of 148 HCWs from the ORCHESTRA cohort to determine its reliability, convergent validity, and accuracy.

RESULTS

Our literature review identified 15 validated questionnaires. After exclusion, 32 items were sent for content validation by experts, yielding five final items that proceeded with the pilot test. Resulting in a Cronbach's alpha-coefficient of .83 for the scale and .78 for dichotomous responses, demonstrating good internal consistency and convergent validity. The result of our accuracy test yielded sensitivity (90.6%) and specificity (91.6%) for the OEEQ scale; and sensitivity (88.7%) and specificity (89.5%) for OEEQ dichotomous responses.

CONCLUSION

This study developed and validated the ORCHESTRA Emotional Exhaustion Questionnaire, demonstrating the questionnaire's clarity, relevance, and comprehensibility in screening emotional exhaustion among HCWs.

Club Cells-A Guardian against Occupational Hazards

Club cells have a distinct role in the epithelial repair and defense mechanisms of the lung. After exposure to environmental pollutants, during chronic exposure, the secretion of club cells secretory protein (CCSP) decreases. Exposure to occupational hazards certainly has a role in a large number of interstitial lung diseases. According to the American Thoracic Society and the European Respiratory Society, around 40% of the all interstitial lung disease is attributed to occupational hazards. Some of them are very well characterized (pneumoconiosis, hypersensitivity pneumonitis), whereas others are consequences of acute exposure (e.g., paraquat) or persistent exposure (e.g., isocyanate). The category of vapors, gases, dusts, and fumes (VGDF) has been proven to produce subclinical modifications. The inflammation and altered repair process resulting from the exposure to occupational respiratory hazards create vicious loops of cooperation between epithelial cells, mesenchymal cells, innate defense mechanisms, and immune cells. The secretions of club cells modulate the communication between macrophages, epithelial cells, and fibroblasts mitigating the inflammation and/or reducing the fibrotic process. In this review, we describe the mechanisms by which club cells contribute to the development of interstitial lung diseases and the potential role for club cells as biomarkers for occupational-related fibrosis.

Recognition of COVID-19 with occupational origin: a comparison between European countries

OBJECTIVES

This study aims to present an overview of the formal recognition of COVID-19 as occupational disease (OD) or injury (OI) across Europe.

METHODS

A COVID-19 questionnaire was designed by a task group within COST-funded OMEGA-NET and sent to occupational health experts of 37 countries in WHO European region, with a last update in April 2022.

RESULTS

The questionnaire was filled out by experts from 35 countries. There are large differences between national systems regarding the recognition of OD and OI: 40% of countries have a list system, 57% a mixed system and one country an open system. In most countries, COVID-19 can be recognised as an OD (57%). In four countries, COVID-19 can be recognised as OI (11%) and in seven countries as either OD or OI (20%). In two countries, there is no recognition possible to date. Thirty-two countries (91%) recognise COVID-19 as OD/OI among healthcare workers. Working in certain jobs is considered proof of occupational exposure in 25 countries, contact with a colleague with confirmed infection in 19 countries, and contact with clients with confirmed infection in 21 countries. In most countries (57%), a positive PCR test is considered proof of disease. The three most common compensation benefits for COVID-19 as OI/OD are disability pension, treatment and rehabilitation. Long COVID is included in 26 countries.

CONCLUSIONS

COVID-19 can be recognised as OD or OI in 94% of the European countries completing this survey, across different social security and embedded occupational health systems.

Factors associated with exclusive breastfeeding at discharge during the COVID-19 pandemic in 17 WHO European Region countries

BACKGROUND

Exclusive breastfeeding is the optimal infant nutrition, providing infants immunoprotection against many diseases including SARS-CoV-2 infection. Restrictions during the COVID-19 pandemic may have negatively affected breastfeeding practices in maternity care facilities. The aims of the study were to examine exclusive breastfeeding rates at discharge over time and to identify factors associated with exclusive breastfeeding during the pandemic.

METHODS

A cross-sectional survey was conducted among mothers who gave birth in a maternity care facility in the World Health Organization (WHO) European Region countries during the COVID-19 pandemic. The socio-ecological model was employed to examine intrapersonal, interpersonal, organizational, and community/society factors associated with maternal report of exclusive breastfeeding at the time of discharge.

RESULTS

There were 26,709 participating mothers from 17 European Region countries who were included in the analysis. Among the mothers, 72.4% (n = 19,350) exclusively breastfed and 27.6% (n = 7,359) did not exclusively breastfeed at discharge. There was an overall decline in exclusive breastfeeding rates over time (p = 0.015) with a significantly lower rate following the publication of the WHO breastfeeding guidelines on 23 June 2020 (AOR 0.88; 95% CI 0.82, 0.94). Factors significantly associated with exclusive breastfeeding outcomes in the logistic regression analysis included maternal age, parity, education, health insurance, mode of birth, inadequate breastfeeding support, lack of early breastfeeding initiation, lack of full rooming-in, birth attendant, perceived healthcare professionalism and attention, facility room cleanliness, timing of birth, and location of birth.

CONCLUSIONS

Results from the study indicate the decline in exclusive breastfeeding rates in the WHO European Region during the COVID-19 pandemic. Using the socio-ecological model to identify factors associated with breastfeeding outcomes facilitates an integrated and holistic approach to address breastfeeding needs among women across the region. These findings demonstrate the need to augment breastfeeding support and to protect exclusive breastfeeding among mother-infant dyads, in an effort to reverse the declining exclusive breastfeeding rates. The study highlights the need to educate mothers and their families about the importance of exclusive breastfeeding, reduce maternal-infant separation, increase professional breastfeeding support, and follow evidence-based practice guidelines to promote breastfeeding in a comprehensive and multi-level manner.

Quality of health care around the time of childbirth during the COVID-19 pandemic: Results from the IMAgiNE EURO study in Norway and trends over time

OBJECTIVE

To describe maternal perception of the quality of maternal and newborn care (QMNC) in facilities in Norway during the first year of COVID-19 pandemic.

METHODS

Women who gave birth in a Norwegian facility from March 1, 2020, to October 28, 2021, filled out a structured online questionnaire based on 40 WHO standards-based quality measures. Quantile regression analysis was performed to assess changes in QMNC index over time.

RESULTS

Among 3326 women included, 3085 experienced labor. Of those, 1799 (58.3%) reported that their partner could not be present as much as needed, 918 (29.8%) noted inadequate staff numbers, 183 (43.6%) lacked a consent request for instrumental vaginal birth (IVB), 1067 (34.6%) reported inadequate communication from staff, 78 (18.6%) reported fundal pressure during IVB, 670 (21.7%) reported that they were not treated with dignity, and 249 (8.1%) reported experiencing abuse. The QMNC index increased gradually over time (3.68 points per month, 95% CI, 2.83-4.53 for the median), with the domains of COVID-19 reorganizational changes and experience of care displaying the greatest increases, while provision of care was stable over time.

CONCLUSION

Although several measures showed high QMNC in Norway during the first year of the COVID-19 pandemic, and a gradual improvement over time, several findings suggest that gaps in QMNC exist. These gaps should be addressed and monitored.

Women's perspectives on the quality of hospital maternal and newborn care around the time of childbirth during the COVID-19 pandemic: Results from the IMAgiNE EURO study in Slovenia, Croatia, Serbia, and Bosnia-Herzegovina

OBJECTIVE

To assess the quality of maternal and newborn care (QMNC) in countries of the former Yugoslavia.

METHOD

Women giving birth in a facility in Slovenia, Croatia, Serbia, and Bosnia-Herzegovina between March 1, 2020 and July 1, 2021 answered an online questionnaire including 40 WHO standards-based quality measures.

RESULTS

A total of 4817 women were included in the analysis. Significant differences were observed across countries. Among those experiencing labor, 47.4%-62.3% of women perceived a reduction in QMNC due to the COVID-19 pandemic, 40.1%-69.7% experienced difficulties in accessing routine antenatal care, 60.3%-98.1% were not allowed a companion of choice, 17.4%-39.2% reported that health workers were not always using personal protective equipment, and 21.2%-53.8% rated the number of health workers as insufficient. Episiotomy was performed in 30.9%-62.8% of spontaneous vaginal births. Additionally, 22.6%-55.9% of women received inadequate breastfeeding support, 21.5%-62.8% reported not being treated with dignity, 11.0%-30.5% suffered abuse, and 0.7%-26.5% made informal payments. Multivariate analyses confirmed significant differences among countries, with Slovenia showing the highest QMNC index, followed by Croatia, Bosnia-Herzegovina, and Serbia.

CONCLUSION

Differences in QMNC among the countries of the former Yugoslavia during the COVID-19 pandemic were significant. Activities to promote high-quality, evidence-based, respectful care for all mothers and newborns are urgently needed.

Rates of instrumental vaginal birth and cesarean and quality of maternal and newborn health care in private versus public facilities: Results of the IMAgiNE EURO study in 16 countries

OBJECTIVE

To explore the quality of maternal and newborn care (QMNC) during the COVID-19 pandemic by facility type among 16 European countries, comparing rates of instrumental vaginal birth and cesarean.

METHODS

Women who gave birth in the WHO European Region from March 1, 2020, to February 7, 2022, answered a validated online questionnaire. Rates of instrumental birth, instrumental vaginal birth, and cesarean, and a QMNC index were calculated for births in public versus private facilities.

RESULTS

Responses from 25 206 participants were analyzed. Women giving birth in private compared with public facilities reported significantly more frequent total cesarean (32.5% vs 19.0%; aOR 1.70; 95% CI 1.52-1.90), elective cesarean (17.3% vs 7.8%; aOR 1.90; 95% CI 1.65-2.19), and emergency cesarean before labor (7.4% vs 3.9%; aOR 1.39; 95% CI 1.14-1.70) (P < 0.001 for all comparisons), with analyses by country confirming these results. QMNC index results were heterogeneous across countries and regions in the same country and were largely affected by geographical distribution of regions rather than by type of facility alone.

CONCLUSION

The study confirms that births in private facilities have higher odds of cesarean. It also suggests that QMNC should be closely monitored in all facilities to achieve high-quality care, independent of facility type or geographical distribution.

Women's perspectives on the quality of maternal and newborn care in childbirth during the COVID-19 pandemic in Latvia: Results from the IMAgiNE EURO study on 40 WHO standards-based quality measures

OBJECTIVE

To investigate women's perspectives on the quality of maternal and newborn care (QMNC) around the time of childbirth during the COVID-19 pandemic in Latvia, comparing the years 2020 and 2021, among women who went into labor or had a prelabor cesarean.

METHODS

Women giving birth in healthcare facilities in Latvia from March 1, 2020, to October 28, 2021, answered an online questionnaire including 40 WHO standards-based quality measures. Descriptive and multivariate quantile regression analyses were performed to compare QMNC in 2020 and 2021.

RESULTS

2079 women were included in the analysis: 1860 women who went into labor (group 1) and 219 with prelabor cesarean (group 2). Among group 1, 66.4% (n = 99/149) of women received fundal pressure in an instrumental vaginal birth, 43.5% (n = 810) lacked involvement in choices, 17.4% (n = 317) reported suffering abuse, 32.7% (n = 609) reported inadequate breastfeeding support while 5.2% (n = 96) lack of early breastfeeding. A significant reduction in QMNC due to the COVID-19 pandemic was reported by 29.5% (n = 219) and 25.0% (n = 270) of respondents in 2020 and 2021, respectively (P = 0.045). Multivariate analyses highlighted a significantly lower QMNC index for 2020 compared with 2021 (P < 0.001).

CONCLUSION

This first study investigating QMNC in Latvia showed significant gaps in QMNC perceived by respondents, with slightly better results in 2021. Appropriate healthcare strategies to improve health care for women and newborns in Latvia are required.

Quality of maternal and newborn care in Switzerland during the COVID-19 pandemic: A cross-sectional study based on WHO quality standards

OBJECTIVE

To explore quality of maternal and newborn care (QMNC) in healthcare facilities during the COVID-19 pandemic in Switzerland.

METHODS

Women giving birth in Switzerland answered a validated online questionnaire including 40 WHO standards-based quality measures. QMNC score was calculated according to linguistic region and mode of birth. Differences were assessed using logistic regression analysis adjusting for relevant variables.

RESULTS

A total of 1175 women were included in the analysis. Limitations in QMNC during the pandemic were reported by 328 (27.9%) women. Several quality measures, such as deficient communication (18.0%, n = 212), insufficient number of healthcare professionals (19.7%, n = 231), no information on the newborn after cesarean (26.5%, n = 91) or maternal and newborn danger signs (34.1%, n = 401 and 41.4% n = 487, respectively) suggested preventable gaps in QMNC. Quality measures significantly differed by linguistic region and mode of birth. Multivariate analysis established a significantly lower QMNC for women in French- and Italian-speaking regions compared with the German-speaking region. Moreover, in several quality indicators reflecting communication with healthcare providers, women who did not answer the questionnaire in one of the Swiss national languages had significantly worse scores than others. A significant lower QMNC was also found for young and primiparous women and for those who experienced cesarean or instrumental vaginal birth.

CONCLUSION

Women giving birth in Switzerland during the pandemic reported notable gaps in QMNC. Providers should be attuned to women who are younger, primiparous, and those who had an emergency cesarean or instrumental vaginal birth given the lower QMNC reported by these groups. Women who did not respond in a Swiss national language may need improved communication strategies.

Women's assessment of the quality of hospital-based perinatal care by mode of birth in Romania during the COVID-19 pandemic: Results from the IMAgiNE EURO study

OBJECTIVE

To assess women's perceptions of the quality of maternal and newborn care (QMNC) received in hospitals in Romania during the COVID-19 pandemic by mode of birth.

METHODS

A validated anonymous online questionnaire based on WHO quality measures. Subgroup analysis of spontaneous vaginal birth (SVB), emergency cesarean, and elective cesarean and multivariate analyses were performed, and QMNC indexes were calculated. Maternal age, educational level, year of birth, mother born in Romania, parity, type of hospital, and type of professionals assisting the birth were used for multivariate analysis.

RESULTS

A total of 620 women completed the survey. Overall, several quality measures suggested gaps in QMNC in Romania, with the lowest QMNC indexes reported for provision of care and availability of resources. Women who had either elective or emergency cesarean compared with those who had SVB more frequently lacked early breastfeeding (OR 2.04 and 2.13, respectively), skin-to-skin contact (OR 1.73 and 1.75, respectively), rooming-in (OR 2.07 and 1.96, respectively), and exclusive breastfeeding at discharge (OR 2.27 and 1.64, respectively). Compared with elective cesarean, emergency cesarean had higher odds of ineffective communication by healthcare providers (OR 1.65), lack of involvement in choices (OR 1.58), insufficient emotional support (OR 2.07), and no privacy (OR 2.06). Compared with other modes of birth, a trend for lower QMNC indexes for emergency cesarean was observed for all domains, while for elective cesarean the QMNC index for provision of care was significantly lower.

CONCLUSION

Quality indicators of perinatal care remain behind targets in Romania, with births by cesarean the most affected.

Regional differences in the quality of maternal and neonatal care during the COVID-19 pandemic in Portugal: Results from the IMAgiNE EURO study

OBJECTIVE

To compare women's perspectives on the quality of maternal and newborn care (QMNC) around the time of childbirth across Nomenclature of Territorial Units for Statistics 2 (NUTS-II) regions in Portugal during the COVID-19 pandemic.

METHODS

Women participating in the cross-sectional IMAgiNE EURO study who gave birth in Portugal from March 1, 2020, to October 28, 2021, completed a structured questionnaire with 40 key WHO standards-based quality measures. Four domains of QMNC were assessed: (1) provision of care; (2) experience of care; (3) availability of human and physical resources; and (4) reorganizational changes due to the COVID-19 pandemic. Frequencies for each quality measure within each QMNC domain were computed overall and by region.

RESULTS

Out of 1845 participants, one-third (33.7%) had a cesarean. Examples of high-quality care included: low frequencies of lack of early breastfeeding and rooming-in (8.0% and 7.7%, respectively) and informal payment (0.7%); adequate staff professionalism (94.6%); adequate room comfort and equipment (95.2%). However, substandard practices with large heterogeneity across regions were also reported. Among women who experienced labor, the percentage of instrumental vaginal births ranged from 22.3% in the Algarve to 33.5% in Center; among these, fundal pressure ranged from 34.8% in Lisbon to 66.7% in Center. Episiotomy was performed in 39.3% of noninstrumental vaginal births with variations between 31.8% in the North to 59.8% in Center. One in four women reported inadequate breastfeeding support (26.1%, ranging from 19.4% in Algarve to 31.5% in Lisbon). One in five reported no exclusive breastfeeding at discharge (22.1%; 19.5% in Lisbon to 28.2% in Algarve).

CONCLUSION

Urgent actions are needed to harmonize QMNC and reduce inequities across regions in Portugal.

Individual and country-level variables associated with the medicalization of birth: Multilevel analyses of IMAgiNE EURO data from 15 countries in the WHO European region

OBJECTIVE

To investigate potential associations between individual and country-level factors and medicalization of birth in 15 European countries during the COVID-19 pandemic.

METHODS

Online anonymous survey of women who gave birth in 2020-2021. Multivariable multilevel logistic regression models estimating associations between indicators of medicalization (cesarean, instrumental vaginal birth [IVB], episiotomy, fundal pressure) and proxy variables related to care culture and contextual factors at the individual and country level.

RESULTS

Among 27 173 women, 24.4% (n = 6650) had a cesarean and 8.8% (n = 2380) an IVB. Among women with IVB, 41.9% (n = 998) reported receiving fundal pressure. Among women with spontaneous vaginal births, 22.3% (n = 4048) had an episiotomy. Less respectful care, as perceived by the women, was associated with higher levels of medicalization. For example, women who reported having a cesarean, IVB, or episiotomy reported not feeling treated with dignity more frequently than women who did not have those interventions (odds ratio [OR] 1.37; OR 1.61; OR 1.51, respectively; all: P < 0.001). Country-level variables contributed to explaining some of the variance between countries.

CONCLUSION

We recommend a greater emphasis in health policies on promotion of respectful and patient-centered care approaches to birth to enhance women's experiences of care, and the development of a European-level indicator to monitor medicalization of reproductive care.

The Pathological Links between Adiposity and the Carpal Tunnel Syndrome

An association between obesity and carpal tunnel syndrome is found in many epidemiological studies. Therefore, there is a need to evaluate the physiopathological links that could explain the association between these two entities. Ectopic adipose tissue is responsible for metabolic syndrome and inflammation, and is a major risk factor for diabetes and cardiovascular diseases. Taking these elements into consideration, we conducted an extensive literature revision of the subject, considering as ectopic fat-related mechanisms the following: (a) the direct compression and the association with the metabolic syndrome of the fat deposition around the wrist, (b) the insulin resistance, dyslipidemia, inflammatory, and oxidative mechanisms related to the central deposition of the fat, (c) the impaired muscle contraction and metabolism related to myosteatosis. Each section presents the cellular pathways which are modified by the ectopic deposition of the adipose tissue and the impact in the pathogeny of the carpal tunnel syndrome. In conclusion, the experimental and clinical data support the epidemiological findings. Efforts to reduce the obesity epidemics will improve not only cardio-metabolic health but will reduce the burden of the disability-free life expectancy due to the carpal tunnel syndrome.

Quality of facility-based maternal and newborn care around the time of childbirth during the COVID-19 pandemic: online survey investigating maternal perspectives in 12 countries of the WHO European Region

BACKGROUND

Multi-country studies assessing the quality of maternal and newborn care (QMNC) during the COVID-19 pandemic, as defined by WHO Standards, are lacking.

METHODS

Women who gave birth in 12 countries of the WHO European Region from March 1, 2020 - March 15, 2021 answered an online questionnaire, including 40 WHO Standard-based Quality Measures.

FINDINGS

21,027 mothers were included in the analysis. Among those who experienced labour (N=18,063), 41·8% (26·1%- 63·5%) experienced difficulties in accessing antenatal care, 62% (12·6%-99·0%) were not allowed a companion of choice, 31·1% (16·5%-56·9%) received inadequate breastfeeding support, 34·4% (5·2%-64·8%) reported that health workers were not always using protective personal equipment, and 31·8% (17·8%-53·1%) rated the health workers' number as "insufficient". Episiotomy was performed in 20·1% (6·1%-66·0%) of spontaneous vaginal births and fundal pressure applied in 41·2% (11·5% -100%) of instrumental vaginal births. In addition, 23·9% women felt they were not treated with dignity (12·8%-59·8%), 12·5% (7·0%-23·4%) suffered abuse, and 2·4% (0·1%-26·2%) made informal payments. Most findings were significantly worse among women with prelabour caesarean birth (N=2,964). Multivariate analyses confirmed significant differences among countries, with Croatia, Romania, Serbia showing significant lower QMNC Indexes and Luxemburg showing a significantly higher QMNC Index than the total sample. Younger women and those with operative births also reported significantly lower QMNC Indexes.

INTERPRETATION

Mothers reports revealed large inequities in QMNC across countries of the WHO European Region. Quality improvement initiatives to reduce these inequities and promote evidence-based, patient-centred respectful care for all mothers and newborns during the COVID-19 pandemic and beyond are urgently needed.

FUNDING

The study was financially supported by the Institute for Maternal and Child Health IRCCS Burlo Garofolo, Trieste, Italy.

Quality of care at childbirth: findings of IMAgiNE EURO in Italy during the first year of the COVID‐19 pandemic

Objective

Investigate the quality of maternal and newborn care (QMNC) during childbirth in the first year of COVID‐19 pandemic in Italy, from the mothers' perspective, as key service users.

Methods

Women who gave birth in an Italian facility from March 1, 2020 to February 29, 2021 answered an online questionnaire including 40 WHO Standard‐based Quality Measures. Descriptive and multivariate quantile regression analyses were performed.

Results

In total, 4824 women were included, reporting heterogeneity of practices across regions: among 3981 women who underwent labour 78.4% (63.0%–92.0%) were not allowed a companion of choice, 44.6% (28.9%–53.3%) had difficulties in attending routine antenatal visits, 36.3% (24.9%–61.1%) reported inadequate breastfeeding support, 39.2% (23.3%–62.2%) felt not involved in medical choices, 33.0% (23.9%–49.3%) experienced unclear communication from staff, 24.8% (15.9%–39.4%) were not always treated with dignity and 12.7% (10.1%–29.3%) reported abuses. Findings in the group of women who did not experience labour were substantially similar. Multivariate analyses confirmed a significant lower QMNC index for regions in southern Italy compared to North and Central regions.

Conclusion

Mothers reported substantial inequities in the QMNC across Italian regions. Future studies should monitor QMNC over time. Meanwhile, actions to ensure high QMNC for all mothers and newborns across Italy are urgently required.

Mothers giving birth in the first year of the COVID‐19 pandemic reported substantial inequities across Italian regions in the QMNC around the time of childbirth.

Antioxidants in Hops: Bioavailability, Health Effects and Perspectives for New Products

Hop plant (Humulus lupulus L.) has been used by humans for ages, presumably first as a herbal remedy, then in the manufacturing of different products, from which beer is the most largely consumed. Female hops cones have different useful chemical compounds, an important class being antioxidants, mainly polyphenols. This narrative review describes the main antioxidants in hops, their bioavailability and biological effects, and the results obtained by now in the primary and secondary prevention of several non-communicable diseases, such as the metabolic syndrome related diseases and oncology. This article presents in vitro and in vivo data in order to better understand what was accomplished in terms of knowledge and practice, and what needs to be clarified by additional studies, mainly regarding xantohumol and its derivates, as well as regarding the bitter acids of hops. The multiple protective effects found by different studies are hindered up to now by the low bioavailability of some of the main antioxidants in hops. However, there are new promising products with important health effects and perspectives of use as food supplements, in a market where consumers increasingly search for products originating directly from plants.

Occupational Asthma: The Knowledge Needs for a Better Management

The management of occupational asthma (OA) may be influenced by several factors and removal from exposure is the main tertiary prevention approach, but it is not always feasible without personal and socioeconomic consequences. Reducing the delay between the onset of suggestive symptoms of OA and the diagnosis of OA is associated with a better prognosis. Workers' education to increase awareness to trigger agents and a medical surveillance program directed especially at at-risk workers could be helpful in reducing this latency time. An early identification of workers who develop rhinitis and conjunctivitis which often precede the onset of asthma symptoms could be important for an early identification of OA. This is particularly important for cases of asthma caused by high-molecular-weight sensitizers and in the early years of employment. The availability of financial support and compensation measures for workers with OA may influence the latency time before diagnosis and, consequently, may influence the OA outcomes. In conclusion, there is a need for high-quality cohort studies that will increase knowledge about risk factor that may influence the timing of diagnosis of OA. This knowledge will be useful for implementation of future surveillance and screening programs in workplaces.

Dark Chocolate: To Eat or Not to Eat? A Review

Dark chocolate is not the most popular chocolate; the higher concentration in antioxidants pays tribute to the increment in bitterness. The caloric density of dark chocolate is potentially lower but has a large variability according to recipes and ingredients. Nevertheless, in the last decade, the interest in dark chocolate as a potential functional food has constantly increased. In this review, we present the nutritional composition, factors influencing the bioavailability, and health outcomes of dark chocolate intake. We have extracted pro- and counter-arguments to illustrate these effects from both experimental and clinical studies in an attempt to solve the dilemma. The antioxidative and anti-inflammatory abilities, the cardiovascular and metabolic effects, and influences on central neural functions were selected to substantiate the main positive consequences. Beside the caloric density, we have included reports placing responsibility on chocolate as a migraine trigger or as an inducer of the gastroesophagial reflux in the negative effects section. Despite an extensive literature review, there are not large enough studies specifically dedicated to dark chocolate that took into consideration possible confounders on the health-related effects. Therefore, a definite answer on our initial question is, currently, not available.

Increased Exhalated Carbon Monoxide, Smoking and Obstructive Sleep Apnea

Although exhaled carbon monoxide (CO) is studied from decades, a few studies are about its levels in smokers with obstructive sleep apnea (OSA). The average level of exhaled CO (eCO) was determined in OSA smokers and found increased significantly higher than in patients with other breathing related sleep disorders. A gender significant difference in average eCO was also noticed, with higher numbers in men, in OSA patients. A threshold of the eCO � 6 ppm has 100% specificity and 96.3% sensitivity in detection of the active smoking habit in patients with OSA. Among OSA comorbidities, only chronic obstructive pulmonary disease (COPD) seams to influence the increased eCO levels in OSA active smokers.

Inflammation Markers in the Evolution of Asbestosis

Asbestos structure and composition contribute to the lung injury and to the inflammation induced by this natural fiber. The result of this study is that neutrophile to lymphocyte ratio correlates significantly to timing of progress of the radiological lesions in the evolution of patients with asbestosis, followed for 5 years. If confirmed in larger studies, this could become a cost-effective biomarker for the asbestosis evolution.

Relationship Between Intermittent Hypoxia,Nocturnal Voiding and Sleep Related Breathing Disorders

Nocturia, cardio-vascular diseases and diabetes are frequent in patients with sleep related breathing disorders. In this study, we had analyzed the influence of the intermittent hypoxia on nocturia prevalence and found that cardio-vascular diseases, obesity, age and apnea hypopnea indexpredict 27.1% of nocturia�s variance (Nagelkerke R square-=.271, c2= 68.35).In AHI [28, the chance of nocturia is 50% and the difference dependents on the presence or absence of the cardio-vascular diseases. For values of AHI ]28, the risk of nocturia becomes independent of the presence of the cardio-vascular disease.

The Adipokine Profile and the Cardiometabolic Risk in Non-Obese Young Adults

Background

Young, non-obese adults are considered at low risk for cardiometabolic diseases, although markers of an unhealthy metabolic state are not uncommon findings in this population. Adipose tissue dysfunction, evaluated by the adipokine profile, significantly influences lipid and glucose metabolism and low-grade systemic inflammation.

Aims

To determine the relation between adipose tissue dysfunction and the already confirmed cardiometabolic risk indicators, including the atherogenic index of plasma, lipid accumulation product, homeostatic model assessment of insulin resistance, and the low-grade inflammation markers, namely, interleukin 6 and high-sensitivity C-reactive protein.

Study Design

Cross-sectional study.

Methods

We recruited 93 non-obese, healthy young adults. Anthropometric, lipid profile, inflammatory markers, and adipokines were measured. An abnormal adipokine profile (high leptin-to-adiponectin ratio) was considered as a marker of a dysfunctional adipose tissue. The correlation between the leptin-to-adiponectin ratio and the anthropometric measurements, atherogenic index of plasma, lipid accumulation product, homeostatic model assessment of insulin resistance, interleukin 6, and high-sensitivity C-reactive protein was determined.

Results

We found a direct correlation between the abnormal adipokine profile and the cardiometabolic risk indicators mentioned above, except for the low-grade inflammatory markers. In the regression model derived from our data, the leptin-to-adiponectin ratio was best correlated with the unfavorable plasma lipid profile, as estimated by the atherogenic index of plasma (r=0.097, confidence interval=0.015-0.180, p=0.021). A significantly higher leptin-to-adiponectin ratio was found in the insulin-resistant group (p=0.012) and in the highest lipid accumulation product quartile (p=0.032).

Conclusion

In a non-obese young population, the high rate of leptin-adiponectin may be a good predictor of cardiovascular and metabolic risk assessment.

Vitamin D Intake and Obesity in Occupational Asthma Patients and the Need for Supplementation

BACKGROUND

Occupational asthma occurs in a significant number of adult unset forms of asthma. Even after exposure cessation, persistent asthma is frequent. Although recognized as important, nutrition, specifically vitamin D intake, was rarely evaluated in occupational asthma.

OBJECTIVE

To assess the vitamin D intake in occupational asthma patients and the relation with body mass index, co-morbidities related to vitamin D deficit, lung function and quality of life.

RESULTS

We found a reduced vitamin D intake in both irritant and allergic asthma, in obese and nonobese patients. The average intake in non-obese patients, although higher, did not reach statistical significance. We also found lower vitamin D intake in the mild asthma group versus the severe group, marginally reaching the significance level (p=0.056) at the median test. Regression analysis in asthma subpopulations revealed a different pattern of correlation, with a stronger relationship between the BMI and the impact score in irritant asthma and a closer link between vitamin D intake and symptoms score (p= 0.027) in the allergic asthma group.

CONCLUSION

The relation between obesity and vitamin D on clinical scores and lung function seems to be different according to the asthma phenotype. However, our study supports the usefulness of nutritional interventions in all occupational asthma patients, targeting both the reduction of the fat mass and the achievement of the recommended daily intake of vitamin D. When analyzing the impact of the weight loss effect on asthma evolution, the vitamin D status should also be considered as an influencer.

The Clinical Implications of Carbon Dioxide Increased Level in Arterial Blood Related to Severe Exacerbations of Chronic Obstructive Pulmonary Disease

In the evolution of patients with chronic obstructive pulmonary disease (COPD), exacerbations occur, especially, in severe stages, determining aggravated respiratory failure and decreased survival. In order to evaluate the implications of COPD exacerbations in patients with second type of chronic respiratory failure and hypercapnic encephalopathy, a prospective observational study was done among 195 COPD in patients of Targu Mures Clinical County Hospital, Romania. Inclusion criteria consisted in severe exacerbations of COPD, complicated by hypercapnia, defined by an increased level of arterial blood gas carbon dioxide (PaCO2) �45 mmHg, suggestive for the second type of respiratory failure. The increased values of PaCO2 ranged between 45 and 112 mmHg among 95 patients. The prevalence of hypercapnia in COPD patients, admitted in hospital for severe exacerbations, was high (n=91/195; 46.66%). The majority of COPD patients (93.4%) were initially hospitalized in the intensive care unit (ICU) department because of hypercapnic encephalopathy. The mortality rate was higher among patients with endotracheal tube insertion than in patients treated by noninvasive mechanical ventilation. High levels of hypercapnia, conscience disorders and respiratory acidosis may be considered factors of severity in COPD exacerbation.

Serum Aminotransferases and the Severity of Asthma

The serum enzymes are ideal diagnostic or prediction markers. Aspartate aminotransferase (AST), a mitochondrial and cytoplasmic enzyme, is one of the well-known markers of hepatic, myocardial or skeletal muscle cytolysis, while alanine aminotransferase (ALT) is mainly a hepatic cytoplasmic enzyme. The normal plasmatic values of AST and of ALT reflect a physiological cell turnover. Therefore, both high and low levels of serum liver enzymes might have a clinical significance. We have conducted a retrospective study targeting the association between the serum AST and ALT levels and the lung function impairment among patients with occupational asthma but without hepatic, cardiac, renal or muscular disorders. Our data show a significant relation (R = 0.54, p [0.05) between the parameters of obstructive ventilator syndrome and AST and ALT levels, respectively (R =0.42, p [0.05). If this relation is confirmed in prospective studies, serum AST and ALT could become useful markers in monitoring asthma patients.

Lung Function and Quality of Life in Workers with Chemical and Dust Exposure

Regarding the widely distribution of respiratory exposure hazards in occupational settings, workers have an increased risk for chronic lung diseases. For assessing the quality of life and lung function in workers exposed to chemicals and dust, St George�s Respiratory Questionnaire (SGRQ) and spirometry were performed among 40 patients, admitted in Occupational Clinic Department of Colentina Hospital, Bucharest, Romania, during February, 2017. SGRQ showed different predictors for patients according to their occupational exposure and total symptoms score correlated better with decreased spirometric parameters in defining lung function deterioration. Quality of life is earlier affected than lung function deterioration and emphasises the need of more sensitive methods for an earlier identification and better evaluation of respiratory hazards in different workplaces.

Glycosylated Hemoglobin and the Severity of Sleep Obstructive Apnea

This research revealed a strong relation between apnea- hypopnea index (AHI), average blood oxygen saturation (avSpO2) measured with the pulse oximeter, oxygen desaturation index (ODI) and glycosylated hemoglobin (HbA1c) in obstructive sleep apnea (OSA) patients, not previously diagnosed with diabetes. Data from biochemistry, fundamental biology and previous clinical monitoring reports were integrated in interpreting this relation. The analysis concluded that high levels of HbA1c limit the relevance of avSpO2 in evaluating OSA severity. ODI maintains a strong association with AHI in high levels HbA1c group.
