No full textHard enough to manage my emotions: How hardiness moderates the relationship between emotional demands and exhaustion
No full textThe frequency of conflicts with patients’ families is one of the main contributors to the amount of emotional demands that healthcare professionals must tackle to prevent the occurrence of burnout symptoms. On the other hand, research evidence suggests that hardiness could enable healthcare professionals to handle their responsibilities and problems effectively. Based on the health impairment process of the Job Demands–Resources model, the main goal of this study was to delve deeper into the relationship between conflict with patients’ families, emotional demands, and exhaustion, as well as to test the buffering role of hardiness. Data were collected from a sample of N = 295 healthcare professionals working in a private hospital in Northern Italy. Most of them were women (78.6%) with a mean age of 40.62 years (SD = 9.50). The mediation of emotional demands within the association between conflict with families and emotional exhaustion and the moderating role of hardiness was tested using a bootstrapping approach. In the current sample, emotional demands mediated the association between conflict with families and exhaustion among healthcare professionals. Moreover, this relationship decreased among individuals with higher levels of hardiness. These findings contribute to the current understanding of the negative impact played by conflict with families on healthcare professionals’ psychological well-being. Furthermore, they corroborated the role of hardiness as a personal resource that could prevent the occurrence of burnout symptoms. In addition to manage—and decrease—episodes of conflict with patients and their families, organizations in the healthcare sector should develop interventions aimed at fostering employees’ hardiness and, consequently, tackle job demands ingrained in their profession (i.e., emotional demands)
Vegetarian diet and oral health: a narrative review
No full textVegetarian diet is a type of diet based on the exclusion of all kind of meat and fish, that can be clas-sified into: vegetarian diet (no meat consumption), semivegetar-ian diet (occasional meat con-sumption), lacto-ovo-pesco-vege-tarian diet (fish consumption) and vegan diet (no animal products). Recently, this type of dietary regi-men has become popular among the eating habits of a part of the population in several countries around the world. The increase in the number of vegetarians and vegans is linked to a greater con-cern for their own health, as well as ethical, environmental and so-cial reasons. Many scientific evidences report that a plant-based diet exerts the greatest preventive effect on the risk of onset of chronic diseases such as diabetes, respects nutri-tional needs at different ages, and represents the one with the small-est ecological footprint. However, those who follow a vegetarian/ vegan diet often consume many refined and ultra-processed foods resulting in an increased likeli-hood of developing heart and metabolic diseases. Subjects who follow a plant-based diet appear to exhibit good oral health, correlating with an interest in prevention and treatment of conditions such as tooth decay and gingivitis. Some studies sug-gest a multifactorial etiology for so-called “white spot” lesions and erosions, for which dietary habits, such as plant-based diets, could play a significant etiologic role. In the context of a plant-based di-et, analysis of macronutrients and micronutrients is of paramount importance. Specifically, vegetari-ans/vegans tend to have higher intakes of vitamin C, which is im-portant in immune system de-fense processes and correlates with less severity of periodontal disease, vitamin A, which cor-relates with less periodontal dis-ease activity, and vitamin E; con-versely, a deficiency of omega-3, with less anti-inflammatory ac-tion in the acute stages of peri-odontal disease, calcium, vitamin D, and vitamin B may be ob-served. Malnutrition is a critical factor in oral mucosal health and proper functioning of the immune sys-tem. Micronutrient deficiency – including trace elements, vita-mins, and antioxidants – dysreg-ulates the host’s natural defense response by suppressing im-mune function. The same micro-nutrients also play an important role in regenerative processes against oxidative stress products in tissues. A statistically significant correla-tion is observed between squa-mous cell carcinoma develop-ment in the oral cavity and a non-vegetarian diet: a diet rich in fiber may be protective against tu-mor onset, as well as against the occurrence of leukoplakia, known to be a pre-cancerous lesion, and submucosal fibrosis. In patients with oral lichen planus, lower levels of nutrients such as calcium, vitamin D, vitamin B12, folic acid, and antioxidants such as vitamins C and E have been found; in addition, vitamin B12 deficiency has been linked to in-creased lesion severity and risk of dysplasia. A plant-based diet, if not properly planned, can induce deficiencies of the micronutrients described above: the vegan diet, even if well structured, can be included in the list of risk factors for hypovitamin-osis B12 and D
A Three-Wave Study on the Reciprocal Relationships between Emotional Dissonance, Need for Recovery, and Exhaustion
No full textAcademic literature has recognized teaching as a particularly stressful occupation,
specifically, the research confirmed the central role of emotional dissonance in the experience
of emotional exhaustion. Albeit previous studies confirm the existence of circular dynamics involving
job demands and individual’s well-being, studies focusing on the long-term relationships between
job demands, need for recovery, and emotional exhaustion are still lacking. Therefore, the aim of the
present study was to explore how emotional dissonance, need for recovery, and emotional exhaustion
are related over time. By using the general framework of the health impairment process of the Job
Demands-Resources model, these paths were investigated by means of a three-wave longitudinal
design (n = 107 schoolteachers). Results of structural equation modeling analyses generally supported
our hypotheses. Specifically, it was found that the model with reciprocal relationships between
emotional dissonance and exhaustion on the one hand, and between need for recovery and exhaustion
on the other, exhibited the best fit with the data

Notes:— Handel-Mazzetti (1931) described Delphinium umbrosum on the basis of a single collection, HandelMazzetti 7809 (WU; Fig. 7), from Zhongdian county in northwestern Yunnan, China. In the protologue, the author stated that this species was related to D. delavayi Franchet (1886: 379), but the latter species differed by having thicker leaves, lanceolate and sessile bracts, much less reflexed spur, much more obliquely truncate upper petals, densely ciliate lateral petals, and very pilose ovaries (“Affine D. Delavayi Franch. quod differt foliis crassioribus, bracteis lanceolatis sessilibus, calcare multo minus reflexo, petalis superioribus multo obliquius truncates, lateralibus crebre ciliatis, ovaries valde pilosis”). Since its description, D. umbrosum has been recognized as an independent species by Wang (1962, 1979 a, 1993, 1997, 2000, 2020), Munz (1968), and Wang & Warnock (2001). Wang (1962) referred ten collections to Delphinium umbrosum, including C.W. Wang 69050 (PE), C.W. Wang 69052 (PE) from Deqen county in northwestern Yunnan and T.T. Yu 979 (PE), J.Q. Hu et al. 3824 (PE), J.Q. Hu et al. 3859 (PE) all from Yuexi county, J.Q. Hu et al. 1132 (PE), J.Q. Hu et al. 1554 (PE), J.Q. Hu et al. 1607 (PE), J.Q. Hu et al. 4248 (PE) all from Hongxi county (now Meigu county), and T.T. Yu 3417 (PE) from Leibo county all in southwestern Sichuan. Wang (1965) considered that only the two Yunnan collections (Fig. 8) belonged to D. umbrosum. He thus described a new variety, D. umbrosum var. hispidum, to accommodate the Sichuan collections, with J.Q. Hu et al. 1607 (PE; Fig. 12A) designated as holotype. He stated that the new variety differed from the type variety, var. umbrosum, by having stem proximally spreading hispid (vs. retrorsely puberulent) and thinner (vs. thicker) (2‒3.5 mm vs. 5‒10 mm in diameter). This treatment was accepted by Wang (1979a, 2020) and Wang & Warnock (2001). We have examined all the type material of Delphinium umbrosum var. hispidum and determined that this variety is identical with D. omeiense, a species described on the basis of six collections also from southwestern Sichuan and since its description generally recognized by Wang (1979 a, 1984, 2000, 2016, 2020), Wang & Wang (2000), Wang & Warnock (2001), and Xie (2016). In fact, the four sheets of Sichuan Econ. Pl. Exped. 1607 (PE; Fig. 12A–D), which constitute the type collection of D. umbrosum var. hispidum, belong also to a paratype collection of D. omeiense (Wang 1979b; Fig. 12B), because J.Q. Hu et al. 1607 and Sichuan Econ. Pl. Exped. 1607 are actually the same collection, with Hu as the leading participant of the expedition (Fig. 12C). Our critical examination indicates that this collection is not mixed, comprising only one taxon. We will deal with D. omeiense in detail elsewhere; in addition to D. umbrosum var. hispidum, several other names should also be reduced to the synonymy of this species.Published as part of Yuan, Qiong & Yang, Qin-Er, 2022, Taxonomic studies on the genus Delphinium (Ranunculaceae) from China (XXII): Clarifying morphological distinction between D. drepanocentrum and D. umbrosum and synonymizing D. umbrosoides with D. drepanocentrum, pp. 243-258 in Phytotaxa 572 (3) on pages 250-257, DOI: 10.11646/phytotaxa.572.3.3, http://zenodo.org/record/732218
