Unraveling the complex link between vitamin D levels and cancer: A crucial understanding for designing future supplementation approaches

Abstract Numerous studies have underscored the essential role of sunlight in vitamin D synthesis, while other studies have examined the association between dietary supplementation and vitamin D levels in different oncologic indications. In certain oncologic types, low levels of vitamin D correlate with a higher risk of cancer progression or poorer outcomes. On the contrary, the protective role of vitamin D remains ambiguous for some cancers. Given that the majority of cancer patients exhibit vitamin D deficiency or insufficiency, there have been suggestions to adopt supplementation strategies. However, vitamin D modulates and interacts with several molecular pathways. Therefore, it is crucial to contextualize the level and circumstances in which the action of vitamin D is observed. Distinct outcomes may emerge based on factors such as the method of assessing vitamin D levels, the size of the study populations, their genetic background, and the specific cancer type under investigation. In this article, we summarize some of the relevant studies examining the relationship between vitamin D levels and cancer. We further briefly outline the process of vitamin D synthesis and its effects on specific cellular pathways involved in cancer progression, highlighting essential considerations for future vitamin D assessments and supplementation approaches.

Is Ozone therapy an adjunct treatment for SARS-CoV-2 / COVID-19 infection?

Abstract Up to today, there is no specific treatment against SARS-CoV-2 / COVID-19 infection; there the necessity to search for alternatives that help patients with COVID-19. The objective of this study was to review the use of ozone therapy as adjunct treatment for SARS-CoV-2 / COVID-19 infection, highlighting the mechanisms of action, forms of application and current clinical evidence. A systematic review was conducted in electronic databases, searching the terminology Ozone "or" Ozone therapy "and" SARS-CoV-2 or COVID-19 or Coronavirus. Results: nineteen studies were included; ten were editorials, comments, brief reports or reviews, and nine clinical studies. We found that ozone therapy could be favorable for treating patients infected with SARS-CoV-2 / COVID-19, through a direct antiviral effect, regulation of oxidative stress, immunomodulation and improvement of oxygen metabolism. Patients who were treated with ozone therapy responded favorably; therefore, ozone therapy appears to be a promising treatment for patients infected with SARS-CoV-2 / COVID-19. Its mechanism of action justifies its use as an adjuvant therapy; however, scientific evidence is based on case series and clinical trials are necessary to corroborate its effectiveness and safety.

Inorganic element profile of medicinal Cannabis extracts consumed by pediatric patients

Abstract The increasing number of reports of web-based experiences on the success of Cannabis-based therapies in controlling seizures in children suffering from refractory epilepsy have led to efforts by governments and associations to a recent change in legislation. The Brazilian Health Regulatory Agency (ANVISA) allowed the import of Cannabis extracts in 2015 and the registration of the first industrialized drug in 2017. In 2019, ANVISA approved procedures for the granting of a Sanitary Authorization for manufacturing and imports, establishing marketing requirements, prescribing, dispensing, monitoring and surveillance of cannabis products for medicinal purposes. Similar to other consumer products of health concern, is necessary to ensure the quality and health safety of these products worldwide. The aim of the present study to evaluate the presence of As, Cd, Pb, Ni, Cu, Co, Cr and Mn present in Cannabis extracts and resins used in the treatment of pediatric patients with neurological diseases. Samples (48 national and 24 imported) were analyzed by Inductively Coupled Plasma Mass Spectrometry - ICP-MS. The imported extracts presented more homogeneous inorganic element values, while national extracts showed varied levels, thus indicating the highest health risk.

ABSTRACT Introduction: chronic actinic damage is a group of alterations in the structure, function, and appearance of the skin as a result of uncontrolled exposure to ultraviolet radiation. It can cause skin cancer. Objective: to characterize the patients with chronic actinic damage, treated at the Dermatology consultation of Valle Hermoso Community Hospital, in the department of Cochabamba, Bolivia. Materials and methods: a descriptive, prospective clinical study was conducted in a universe of 1,833 patients diagnosed with chronic actinic damage, treated at the Dermatology clinic of the Valle Hermoso Community Hospital, Cochabamba, between September 2017 and September 2018. The variables age, sex, skin color, skin phototype, occupation, use of sun protectors, exposure to other types of radiation, clinical manifestations of photodamage and altitude of the place of residence were evaluated. Results: the age group from 25 to 59 years, the female sex, mestizo skin color (77.08 %), the IV skin phototype (76.98 %) and merchant occupation (72.56 %) predominated. Most patients (82.7 %) did not use sun protection means, and 99.8 % had no other radiation exposure. The prevailing photodamage lesions were melasma (83.03 %) and lentigo (12.22 %). 99.29 % lived in high altitude areas. Conclusions: the patients with chronic actinic damage were characterized, obtaining in some variables studied results similar to those mentioned by other researchers (AU).

Characteristics and Usage Patterns Among 12,151 Paid Subscribers of the Calm Meditation App: Cross-Sectional Survey.

BACKGROUND: Meditation has become increasingly popular due to its health benefits; however, barriers to delivering meditation programs in traditional group-based formats limit the accessibility of these benefits. Smartphone-based meditation may increase the availability of these programs to larger, more diverse audiences; however, research on subscriber characteristics and usage patterns in meditation mobile apps is lacking. OBJECTIVE: This study aimed to describe the demographics, clinical characteristics, and usage patterns of a convenience sample of Calm subscribers and explore the relationship between self-reported app usage and changes in health, stress, and sleep. METHODS: Participants were 12,151 paying Calm subscribers (response rate=12.08%, 12,151/100,594) who completed an anonymous Web-based survey with 11 quantitative questions related to user engagement, reasons for starting Calm, and changes after using the app. Demographic characteristics, chronic health diagnoses, and sleep difficulties were also assessed. Chi-square tests were used to examine differences in app usage. Logistic regression models were used to examine demographic and health characteristics that may predict changes in health, stress, and sleep. RESULTS: Respondents were 18-96 years old (mean 48.57 [SD 13.79]), primarily female (79.94%, 8778/10,981), white (81.41%, 8959/11,005), and most reported a chronic health diagnosis (56.86%, 6289/11,061). Mental health diagnoses (41.13%, 4549/11,061) were more common than physical health diagnoses (32.19%, 3560/11,061). Most respondents (76.31%, 8684/11,360) reported difficulties falling or staying asleep. On average, respondents had been using Calm for 11.49 months (SD 10.49), and 60.03% (7281/12,129) used it 5 or more times per week. Meditations (used by 80.02%, 9497/11,841) and Sleep Stories (55.66%, 6591/11,841) were the most popular components. The frequency of using Calm was associated with incremental increases in the likelihood of noticing changes in mental health (χ22=136.8; P<.001), physical health (χ22=102.8; P<.001), stress (χ22=128.1; P<.001), and sleep (χ22=141.4; P<.001). Respondents who had used Calm longer were also more likely to notice changes in mental health (OR 1.06 [95% CI 1.05 to 1.06]), physical health (OR 1.01 [95% CI 1.01 to 1.02]), stress (OR 1.04 [95% CI 1.04 to 1.05]), and sleep (OR 1.004 [95% CI 1.00 to 1.01]). Subscribers with sleep difficulties used Calm more frequently (χ82=11.5; P=.003), were more likely to use Sleep Stories (χ12=1590.2; P<.001), and were more likely to notice changes in their physical health (χ12=49.2; P<.001) and sleep (χ12=2391.1; P<.001). CONCLUSIONS: Results highlight important demographic characteristics and usage patterns among a self-selected sample of Calm subscribers. Mental health concerns and sleep appear to be top reasons for downloading Calm. Sleep Stories and meditations are the most popular app components. The frequency of using Calm was associated with incremental changes in outcomes. Findings support future randomized controlled trials testing the efficacy of Calm for health, stress, and sleep. Studies should also explore strategies to attract a more diverse sample of subscribers.

Latent class analysis suggests four distinct classes of complementary medicine users among women with breast cancer.

BACKGROUND: Breast cancer patients commonly report using >1 form of complementary and alternative medicine (CAM). However, few studies have attempted to analyze predictors and outcomes of multiple CAM modalities. We sought to group breast cancer patients by clusters of type and intensity of complementary and alternative medicine (CAM) use following diagnosis. METHODS: Detailed CAM use following breast cancer diagnosis was assessed in 2002-2003 among 764 female residents of Long Island, New York diagnosed with breast cancer in 1996-1997. Latent class analysis (LCA) was applied to CAM modalities while taking into account frequency and intensities. RESULTS: Four distinct latent classes of CAM use emerged: 1) "Low-dose supplement users" (40%), who used only common nutritional supplements; 2) "Vitamin/mineral supplement users" (39%), using an abundance of supplements in addition to other practices; 3) "Mind-body medicine users" (12%), with near-universal use of supplements, mind-body medicine techniques, and massage; and 4) "Multi-modality high-dose users" (9%), who were highly likely to use nearly all types of CAM. Predictors of membership in classes with substantial CAM use included younger age, more education, higher income, Jewish religion, ideal body mass index, higher fruit and vegetable intake, higher levels of physical activity, receipt of adjuvant chemotherapy, and prior use of oral contraceptives. CONCLUSIONS: LCA identified important subgroups of breast cancer patients characterized by varying degrees of complementary therapy use. Further research should explore the reproducibility of these classes and investigate the association between latent class membership and breast cancer outcomes.

Plantas medicinais utilizadas pela população do município de Lagarto- SE, Brasil ­ ênfase em pacientes oncológicos / Medicinal Plants Used by the Population of Lagarto, SE, Brazil ­ Emphasis in Cancer Patients

RESUMO A utilização de plantas com fins medicinais é uma das mais antigas formas de prática medicinal da humanidade. Entretanto, o conceito de "natural"; contribui para o pensamento popular e errôneo de que Plantas Medicinais (PM) são sinônimos de produtos seguros, o qual pode ocasionar no desenvolvimento de efeitos adversos ou interações medicamentosas. Neste contexto, foi realizado levantamento etnofarmacológico das Plantas Medicinais (PM) utilizadas no município de Lagarto, SE, Brasil, com ênfase de seu uso por pacientes oncológicos. Um total de 706 moradores foram entrevistados. Foram citadas 80 plantas, das quais 57 foram identificadas em nosso laboratório. O uso de plantas medicinais (MP) para fins terapêuticos foi relatada por 336 (47,65%) entrevistados. As MPs mais utilizados foram: Erva-Cidreira (Lippiaalba (Mill) N. E. Brown - 103, 30,8%), Boldo (Plectranthus barbatus Andr. - 53, 15,7%), e Capim-Santo (Cymbopogon citratus (D.C.) Stapf - 49, 14,6%). Dos entrevistados que relataram o uso de MPs, metade (360, 50,95%) comunicaram ao médico, mas não receberam orientações específicas. As doenças crônicas mais comuns identificadas foram: hipertensão arterial (144, 20,34%), câncer (55, 7,81%) e diabetes (41, 5,89%). Dos pacientes com câncer, cerca de 40% (22) relataram utilizar PMs concomitante com quimioterapia, dado alarmante, visto a possibilidade de interações medicamentosas entre PMs e antineoplásicos. Diante desses dados, foi observado o uso de PM pela população de Lagarto, SE, e por pacientes oncológicos dessa região, porém, sem os mesmos receberem orientações de um profissional qualificado.

Medicinal Plants Used by the Population of Lagarto, SE, Brazil ­ Emphasis in Cancer Patients. The use of plants for medicinal purposes is one of the oldest forms of medical practice. However, the concept of "natural" contributes to the popular and erroneous thinking that Medicinal Plants (PM) are synonymous of safe products, which may result in the development of adverse effects or drug interactions, particularly in cancer patients. In this context, it was conducted an ethnopharmacological survey of MP used in Lagarto, SE, Brazil, with emphasis in cancer patients. A total of 706 residents were interviewed, and they mentioned 80 plants, from which 57 were identified. The use of medicinal plants (MP) for therapeutic purpose was reported by 336 (47.65%) of the participants. The most used MPs were as follows: Bushy Lippia (Lippia alba (Mill) N. E. Brown­ 103, 30.8%), Boldo (Plectranthus barbatus Andr. ­ 53, 15.7%), and Lemon Grass (Cymbopogon citratus (D.C.) Stapf. ­ 49, 14.6%). From the participants who reported the use of MPs, half of them (360, 50.95%) spoke with a doctor but did not receive specific guidelines. The most common chronic diseases identified were: arterial hypertension (144, 20.34%), cancer (55, 7.81%) and diabetes (41, 5.89%). From these cancer patients, approximately 40% of them (22) used MP concomitantly with chemotherapy, an alarming discovery, as drug interactions are possible between MPs and antineoplastics. Given these data, we observed the use of the PM by the population of Lagarto, SE, and by cancer patients of this region, but they did not receive guidance from a qualified professional

Levantamento sobre o uso de plantas medicinais com a terapêutica anticâncer por pacientes da Unidade Oncológica de Anápolis / Survey on medicinal plants used with anticancer therapy by patients from Anapolis Oncology Unit

Este estudo teve por objetivo conhecer o perfil dos pacientes em tratamento contra o câncer da Unidade Oncológica de Anápolis quanto ao uso de plantas medicinais. Foram entrevistados 59 pacientes (42,12% da população estudada) por meio de questionários avaliativos enfatizando características sócio-demográficas e dados referentes à utilização de plantas medicinais. Evidenciou-se o uso indiscriminado de plantas medicinais entre os pacientes. A maioria dos entrevistados compartilha a opinião errônea de que plantas medicinais não fazem mal. A orientação sobre a forma de utilização das plantas ocorre, principalmente, pela informação de familiares ou amigos, e os profissionais da saúde muitas vezes são ignorados neste processo. Constatou-se que as plantas medicinais são utilizadas para o tratamento de enfermidades de baixa a alta gravidade, como o câncer. Dentre as 14 espécies usadas pelos pacientes com finalidade antineoplásica as mais mencionadas foram as popularmente conhecidas como noni, babosa, graviola e romã. Apesar de alguns estudos relatarem atividade antineoplásica ou quimiopreventiva para algumas espécies vegetais, muitas delas podem ser tóxicas ou apresentar potencial risco quando usadas concomitantemente ao tratamento convencional. Desta forma, observa-se que é preciso mais profissionais especializados para orientação sobre o risco de reações adversas e interações medicamentosas no que se refere ao uso de espécies vegetais e a terapêutica do câncer.

This study aims to survey the profile ofcancer patients in the Oncology Unit of Anápolis in relation to the use of medicinal plants. To evaluate socio-demographic characteristics and to retrieve data about on the use of medicinal plants, a questionnaire was filled by 59 patients, or 42.12% of the population under study. A widespread use of plants was found. Most of patients share the wrong idea that medicinal plants are not harmful. Guidance on the use of medicinal plants is given primarily by relatives and friends, and health professional are often ignored in this process. Among the 14 species used by patients with antineoplastic purpose, the most mentioned were popularly species known as "noni", "aloe", "soursop" and "pomegranate". Although some studies have reported chemopreventive or antineoplastic activity for some plant species, many may be toxic or show potential risk when used concurrently with conventional treatment. Thus, we can observe that there is a need for more specialized professionals for the guidance on the risk of adverse reactions and drug interactions in relation to the use of plant species and cancer therapeutics.

Identifying subgroups of complex patients with cluster analysis.

OBJECTIVE: To illustrate the use of cluster analysis for identifying sub-populations of complex patients who may benefit from targeted care management strategies. STUDY DESIGN: Retrospective cohort analysis. METHODS: We identified a cohort of adult members of an integrated health maintenance organization who had 2 or more of 17 common chronic medical conditions and were categorized in the top 20% of total cost of care for 2 consecutive years (n = 15,480). We used agglomerative hierarchical clustering methods to identify clinically relevant subgroups based on groupings of coexisting conditions. Ward's minimum variance algorithm provided the most parsimonious solution. RESULTS: Ward's algorithm identified 10 clinically relevant clusters grouped around single or multiple "anchoring conditions." The clusters revealed distinct groups of patients including: coexisting chronic pain and mental illness, obesity and mental illness, frail elderly, cancer, specific surgical procedures, cardiac disease, chronic lung disease, gastrointestinal bleeding, diabetes, and renal disease. These conditions co-occurred with multiple other chronic conditions. Mental health diagnoses were prevalent (range 28% to 100%) in all clusters. CONCLUSIONS: Data mining procedures such as cluster analysis can be used to identify discrete groups of patients with specific combinations of comorbid conditions. These clusters suggest the need for a range of care management strategies. Although several of our clusters lend themselves to existing care and disease management protocols, care management for other subgroups is less well-defined. Cluster analysis methods can be leveraged to develop targeted care management interventions designed to improve health outcomes.

Vitamin C requirements in parenteral nutrition.

Some biochemical functions of vitamin C make it an essential component of parenteral nutrition (PN) and an important therapeutic supplement in other acute conditions. Ascorbic acid is a strong aqueous antioxidant and is a cofactor for several enzymes. The average body pool of vitamin C is 1.5 g, of which 3%-4% (40-60 mg) is used daily. Steady state is maintained with 60 mg/d in nonsmokers and 140 mg/d in smokers. Shocked surgical, trauma, and septic patients have a drastic reduction of circulating plasma ascorbate concentrations. These low concentrations require 3-g doses/d to restore normal plasma ascorbate concentrations, questioning the recommended PN dose of 100 mg/d. Determination of intravenous requirements is usually based on plasma concentrations, which are altered during the inflammatory response. There is no clear indicator of deficiency: serum or plasma ascorbate concentrations <0.3 mg/dL (20 micromol/L) indicates inadequate vitamin C status. On the basis of available pharmacokinetic data the 100 mg/d dose for patients receiving home PN and 200 mg/d for stable adult patients receiving PN are adequate, but requirements have been shown to be higher in perioperative, trauma, burn, and critically ill patients, paralleling oxidative stress. One recommendation cannot fit all categories of patients. Large vitamin C supplements may be considered in severe critical illness, major trauma, and burns because of increased requirements resulting from oxidative stress and wound healing. Future research should distinguish therapeutic use of high-dose ascorbic acid antioxidant therapy from nutritional PN requirements.

Casemix in the Islamic Republic of Iran: current knowledge and attitudes of health care staff.

Casemix is a tool that classifies patients according to their clinical similarity and the homogeneity of resources required. A descriptive study was conducted to assess the level of knowledge and attitude toward the casemix-based funding system among staff working in the Iranian Social Security Organization in Tehran. The survey showed that knowledge of casemix and diagnosis-related groups (DRG) was poor among the study group and any attempt to implement the casemix system--which about three-quarters of high-level staff had never heard of--would be likely to fail. This highlights the necessity for creating awareness of the casemix and DRG systems among the hospital staff before any action takes place.

Community pharmacists' actions when patients use complementary and alternative therapies with medications.

OBJECTIVE: To assess actions of community pharmacists in response to their patients' concurrent use of prescription medications and complementary and alternative medicine (CAM). DESIGN: Nonexperimental, cross-sectional mail survey. SETTING: Texas. PARTICIPANTS: 107 community pharmacists. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Pharmacists' self-reported rate of patient inquiry about CAM use and actions taken in response to CAM use. RESULTS: A majority (71.0%) of pharmacists had encountered patients who were using CAM, which was defined broadly in the survey to include herbal products, vitamins and minerals, homeopathic products, massage, meditation, and other types of CAM. Pharmacists documented CAM use by patients in 11.0% of cases and reported monitoring for drug-related problems in 38.4% of users. Among CAM users, pharmacists most often encouraged CAM use if medically appropriate. Pharmacists were not comfortable with responding to CAM inquiries but believed they needed adequate knowledge about CAM. In general, pharmacists rarely asked patients about their CAM use. Pharmacists' rate of inquiry about CAM use increased significantly when this information could be documented in patient profiles and when pharmacists had additional training in CAM. Also, in pharmacies that stocked herbal or homeopathic products, pharmacists were significantly more likely to encourage the use of CAM when medically appropriate and to recommend other CAM therapies appropriate for patients' conditions. When no references were available to research CAM, pharmacists tended to neither encourage nor discourage CAM use based on lack of scientific evidence of their effectiveness. CONCLUSION: Most community pharmacists had patients who used CAM, but they were not proactive in inquiring about or documenting this use. They most often encouraged CAM use if deemed medically appropriate. Pharmacists' actions differed on the basis of professional and practice setting characteristics. To ensure optimal drug therapy outcomes, pharmacists should be more proactive in identifying and documenting CAM use by patients.

Eficacia y aplicación de la hipnosis clínica / No disponible

La hipnosis es una técnica potente para la mejora de la calidad de vida de una gran variedad de pacientes. Sin embargo, es frecuente que tanto pacientes como terapeutas tengan creencias erróneas que dificultan que la hipnosis clínica se utilice más. El presente trabajo disipa estas creencias erróneas, destaca la eficacia clínica de la hipnosis y la investigación de vanguardia, y argumenta en favor de un uso más extendido de esta técnica terapéutica adjunta (AU)

Hypnosis is a powerful technique for improving quality of life for a wide variety of patients. Unfortunately, misconceptions about hypnosis are too often held by patients and therapists alike, possibly preventing greater use of clinical hypnosis. The present paper dispels these misconceptions, highlights clinical effectiveness of hypnosis and cutting edge research, and argues for more widespread use of this adjunctive therapeutic technique (AU)

Teoría de hypnosis / No disponible

Durante aproximadamente los últimos 50 años, el estudio y la práctica de la hipnosis se han enmarcado dentro del campo de la Psicología. Este artículo revisa las conclusiones que constituyen un acuerdo emergente entre los científicos sobre los fenómenos fundamentales de la hipnosis, y describe la influencia de las teorías de hipnosis que han tenido una repercusión determinante en el campo, y que no descansan en la idea de que la hipnosis se puede explicar por un "estado de trance" específico de la hipnosis. Estas teorías incluyen la teoría socio-psicológica del rol (ejemplo: Sarbin, Coe), la teoría cognitivo-comportamental (ejemplo: Barber), la teoría neodisociativa (ejemplo: Hilgard), la teoría socio-psicológica de Spanos, la teoría de la expectativa de respuesta (ejemplo: Kirsch), el modelo integrador de Lynn, y la teoría del set de respuesta (ejemplo: Kirsch, Lynn) (AU)

In the past 50 years or so, the study and practice of hypnosis has moved into the mainstream of psychology. This article reviews findings that constitute an emerging consensus among scientists about the basic phenomena of hypnosis and describes influential theories of hypnosis have had a shaping influence on the field and do not rely on the idea that hypnosis can be explained by a "trance state" specific to hypnosis. These theories include social psychological role theory (e.g., Sarbin, Coe), cognitive behavioral theory (e.g., Barber), neodissociation theory (e.g., Hilgard), Spanos’s social psychological theory, response expectancy theory (e.g., Kirsch), Lynn’s integrative model, and response set theory (e.g., Kirsch, Lynn) (AU)

Personalidad, psicopatología y sugestionabilidad hipnótica / No disponible

En esta revisión se contrasta la investigación académica y clínica relacionada con la sugestionabilidad hipnótica. La investigación académica básica usando medidas estandarizadas ha demostrado varias relaciones consistentes y significativas. La investigación sobre el constructo, absorción, y otras variables relacionadas con la habilidad imaginativa parecía prometedora, pero investigación posterior indicó que los resultados estaban influidos por el contexto de la evaluación. En general, la investigación básica sobre personalidad y sugestionabilidad hipnótica indica que pueden haber correlaciones válidas, pero los niveles de las relaciones son bajas. Sin embargo, la investigación clínica sobre la relación de varios síntomas psicopatológicos y síndromes indica la existencia de relaciones significativas entre alta sugestionabilidad hipnótica y psicopatología. Se discute las razones de la discrepancia entre los hallazgos de las investigaciones académicas y clínicas (AU)

Academic and clinical research on correlates of hypnotic suggestibility is contrasted in this review. Basic academic research using standardized measures has yielded few consistent, significant relationships. Research on the construct, absorption, and other variables related to imaginative ability seemed promising, but further research indicated that results were biased by the context of assessment. Overall, basic research on personality and hypnotic suggestibility indicates that there may be some valid correlates, but the levels of the relationships are quite low. However, clinical research on the relationship of various psychopathological symptoms and syndromes indicates a number of meaningful relationships between high hypnotic suggestibility and psychopathology. Reasons for the discrepancy between academic and clinical research findings are discussed (AU)

Method of Patient Classification System in obstetric staff scheduling. I. Criteria and categories of care.

The lack of verified Patient Classification System methods for obstetric care provided incentives for the development of own proposal, which would be adjusted to the conditions in Polish delivery rooms and the mothers' demand for these services. Four main criteria of obstetric care were adopted which corresponded to the subsequent stages of labour. These main criteria were ascribed more than a dozen detailed criteria concerning the specific character of obstetric care, as well as general nursing care. The chart containing the criteria of care facilitated the classification of women in labour into individual categories of obstetric care. Three categories of care were distinguished: Category I of minimum obstetric care, Category II of moderate obstetric care, and Category III of intensified obstetric care.

Method of Patient Classification System in obstetric staff scheduling. II. Demand for direct nursing in the delivery room among mothers who deliver by natural birth.

After the development of categories and criteria of nursing mothers who give birth in the delivery room, the direct nursing time provided for women at childbirth by the midwives in individual categories of care was determined. The model time which should be provided for mothers according to their actual needs was also determined. The results of the study showed that among women who delivered naturally, statistically significant differences were observed between two variables: the nursing time provided and the model time. Hence, for women who deliver naturally it would be advisable that the nursing time standard for midwives resulted from the model times.

Method of Patient Classification System in obstetric staff scheduling. III. Demand for direct nursing in the delivery room among mothers who deliver by Caesarean section.

In own studies concerning the determination of the demand for the direct nursing time in the delivery room, the mothers examined were divided into two groups: those who delivered naturally and those who delivered by Caesarean section. The results of the study showed that no statistically significant differences were observed between the nursing time received from midwives by the women who delivered by Caesarean section and the model time. Therefore, the standards concerning the number of nursing staff for this group of women may be determined based on either provided or model times.
