It promotes the spread of diseases carried by vectors and mass occurrence of arthropods. Millipede can carry infectious agents, invade homes and farms, cause skin irritation in case of exposure to their excretions.The aim of the study was to find information about mass appearances of millipedes and identify the places and periods where it happens.</p> <p>A systematic review of publications available in online scientific databases and the library of the Medical University of Lublin was performed.</p> <p>As many as 5 reports about mass occurrence of millipede were from Japan, 3 from Brazil, 3 from Australia 2 from Germany and Hungary, and single publications from Romania, Norway, Poland and Madagascar. In Japan the 8-year periodicity of millipede outbreaks was observed. Japan and Australia encounter problems at railway due to these organisms. In other countries they are nuisance to people when they enter their dwellings and pose a burden in farming and gardening therefore mechanical, chemical and biological methods of millipede control are tested. On the other hand millipede help in composting organic waste. In conclusion: global climate change is accompanied by an increase in frequency of mass occurrences of millipedes.</p> </abstract>ARTICLE2022-04-05T00:00:00.000+00:00„Cardiovascular Top Three” - Can Patients with the Most Common Cardiovascular Conditions Become Candidates for Recreational Scuba Diving?https://sciendo.com/article/10.2478/phr-2020-0022<abstract> <title style='display:none'>Abstract</title> <p>Cardiovascular diseases such as coronary artery disease, hypertension, and diabetes are some of the most common conditions among the population. An ever-increasing number of recreational divers forces us to consider the impact on unprepared diving patients with cardiovascular diseases, in whom profound changes occur during the dive. People in at-risk groups should have a medical check-up before diving to minimise the risk of possible complications.</p> </abstract>ARTICLE2022-04-05T00:00:00.000+00:00Research on Underwater Directional Swimming Skills of Divershttps://sciendo.com/article/10.2478/phr-2020-0023<abstract> <title style='display:none'>Abstract</title> <p>The article presents the results of research on the application of a physical exercise programme to improve the underwater orientation of military divers.

This paper deals with the implementation of safety measurement systems for online control of the breathing air production process. On the basis of a qualified control system, the capability of the rationalised process was assessed, identifying both its current status and its potential for improvement in terms of eliminating defects caused by excessive carbon dioxide content. For process reasons, the effectiveness of online process monitoring was evaluated against the previously used periodic sample control by means of laboratory methods of instrumental analysis. The analysis was conducted at KTPP AMW<sup>1</sup> for the compressed air supply system of the DGKN - 120<sup>2</sup> complex.</p> </abstract>ARTICLE2022-04-05T00:00:00.000+00:00Loss of Technical and Functional Properties of Elements of Diving Equipment Whilst in Usehttps://sciendo.com/article/10.2478/phr-2020-0021<abstract> <title style='display:none'>Abstract</title> <p>The author undertakes to systematise and compare various types of losses of the technical and functional properties of equipment related to diving with other areas of human activity in which technical equipment is used. The basis for this is the extensive literature describing, inter alia, the issues of wear and tear of machine parts, their damage, failures, etc. a phenomena occurring in the “life” of virtually every technical object. The specificity of diving techniques makes it a relatively little analysed segment of activity from the perspective of exploitation. Based on the analysis of publications and own materials, the author has reviewed and matched them in terms of similarity of loss of technical and functional properties of various elements of diving technology in relation to the divisions and criteria used in generally understood utilisation.</p> </abstract>ARTICLE2022-04-05T00:00:00.000+00:00Selected Risks of the Decompression Process, Part II: Analysis of Selected Types of Riskhttps://sciendo.com/article/10.2478/phr-2020-0014<abstract> <title style='display:none'>Abstract</title> <p>The safe transition from a higher pressure atmosphere to a lower pressure atmosphere is accomplished by planning the decompression process, typically through changes in pressure and/or composition of the breathing mix in a function of time. However, the decompression process is affected by a much greater number of inherent factors than changes in pressure and composition of the breathing mix. Their values should be kept within certain ranges, however, there are circumstances when it is not possible to maintain control over them. In this situation, they become elements of the residual risk of the decompression process. The safety of decompression should be ensured, inter alia, by analysing the residual risk for each execution of the decompression process.</p> </abstract>ARTICLE2021-11-15T00:00:00.000+00:00Research on Underwater Directional Swimming Skills of Divershttps://sciendo.com/article/10.2478/phr-2020-0017<abstract> <title style='display:none'>Abstract</title> <p>The article presents the results of research on the application of a physical exercise programme to improve the underwater orientation of military divers.

Data included in dive logs may vary in detail, however, there is basic information to provide based on global standards. Differently to several developed countries in Europe, North America and Australasia, there are countries with incipient, sometimes non-regulated, SD programmes. In this article the importance of documentation in SD is highlighted and record forms are provided as templates, including versions both in English and Spanish. The Diving Supervisor (DS) is the designated person to fill the ‘Daily SciDive Log’ and ‘SCUBA &amp; surface-supplied LogSheet’ (Table 1, 2 and 3, respectively), whilst every diver is responsible for filing their own ‘SciDiver’s Digital LogBook’ (Table 4). General and specific considerations for all tables are described throughout the text. This effort was done to facilitate systematic data management and start developing the bases towards solid national/regional standards on scientific diving operations, particularly for those countries with incipient (scientific) diving programmes.</p> </abstract>ARTICLE2021-11-15T00:00:00.000+00:00Effects of Different Forms of Extrinsic Feedback on the Accuracy of Force Production and to Differentiate this Force in the Simple Cyclic Movements of the Upper and Lower Limbhttps://sciendo.com/article/10.2478/phr-2020-0016<abstract> <title style='display:none'>Abstract</title> <p><bold>Background:</bold> This study aimed to assess the accuracy of force production by the limbs and to identify the ability to differentiate this force during a progressively increasing value, in response to different types of extrinsic feedback.</p> <p><bold>Material and methods:</bold> The study involved nineteen healthy and physically active boys and girls aged 12.82±0.34 years, body height 157.05±9.02 cm, and body mass 44.89±7.89 kg. The tasks were to perform a series of right and left upper limb pulls and pushes with increasing force using the levers of the kinesthesiometer and a series of lower limb presses on the pedal of the kinesthesiometer. The tasks were completed in three feedback conditions: no feedback, sound feedback, verbal feedback, and the retention test was used. To assess the level of accuracy of force production, the novel index of force production accuracy (FPAIndex) was used.</p> <p><bold>Results:</bold> The outcomes expressing the value of FPAIndex on the point scale indicated that the highest level of kinesthetic differentiation was observed when no feedback was provided (1.17 points), and the lowest kinesthetic differentiation was recorded when verbal feedback was provided (3.33 points). However, they were devoid of statistical value. The repeated-measures analysis of variance ANOVA with the Tukey post-hoc test (HSD) indicated a significant lowest (p=0.0402) level of accuracy of FPA (x̄ 36.12±18.29 [N]) only for the act of left lower limb press (LL PRESS) in the retention test, while no feedback was provided to the subjects.</p> <p><bold>Conclusions:</bold> The results of this study showed that verbal and sound extrinsic feedback did not affect the accuracy of force production by the upper and lower limbs and the ability to differentiate this force in simple movements among children.</p> </abstract>ARTICLE2021-11-15T00:00:00.000+00:00Quality and Quantity Assessment of Groundwaters in the Vicinity of Kutno with Respect to Potability.

Despite numerous studies being conducted around the world, the transformation of mercury in natural environments is still not fully understood. In addition, increasing droughts and heavy rains are currently observed to contribute to changes in the circulation of Hg. The purpose of this study was to recognise the influence of extreme meteorological and hydrological conditions on the inflow of various forms of mercury to the coastal zone of the Bay of Puck. The studies were carried out at estuarial stations of four rivers belonging to the southern Baltic Sea catchment: Reda, Zagorska Struga, Gizdepka and Płutnica. The results showed that meteorological and hydrological parameters affect mercury speciation in river catchments, which translates into inflow of labile mercury to the southern Baltic Sea.</p> </abstract>ARTICLE2021-11-15T00:00:00.000+00:00Analysis of Accidents and Sickness of Divers and Scuba Divers at the Training Centre for Divesr and Scuba Divers of the Polish Armyhttps://sciendo.com/article/10.2478/phr-2020-0013ARTICLE2021-04-30T00:00:00.000+00:00Evaluation of EEG Tests in the Amateur Diving Instructor Group and Correlation with the Occurrence of Sterile Bone Necrosishttps://sciendo.com/article/10.2478/phr-2020-0007<abstract> <title style='display:none'>Abstract</title> <p>The research undertaken was a continuation of previous studies relating to professional divers. The bioelectrical activity of the brain with an electronic electroencephalograph (EEG) was studied in a group of 89 instructors for amateur diving between 21 and 50 years of age. Pathological patterns were found in 15.7% of the subjects. In comparison with professional divers, the disturbances were significantly less frequent, but considerably more frequent in comparison with the control group. There was no relationship between the occurrence of the disorders in relation to the age of the examined person, however, the occurrence of the disorders was more frequent in persons with the least experience. Moreover, a correlation was found in one age group between abnormalities of EEG recording and the occurrence of sterile bone necrosis.</p> </abstract>ARTICLE2021-04-30T00:00:00.000+00:00Diver Poisoning with Contaminated Compresses Airhttps://sciendo.com/article/10.2478/phr-2020-0010<abstract> <title style='display:none'>Abstract</title> <p>The paper describes the case of a military diver who suffered from a complicated poisoning caused by hydrocarbons contained in his breathing air. The hydrocarbons came from a malfunctioning compressor which was used to fill the diving cylinders; the compressor sucked in the exhaust gases of its own motor. Exhaust gas poisoning was further complicated by hypoxia and hypercapnia as the diver spat out the mouthpiece and started to breathe from inside the suit. This resulted in a loss of consciousness. The diver was extracted to the surface and was given oxygen to breathe. The course of treatment was successful. On the same day, symptoms of exhaust gas poisoning occurred in several divers using cylinders filled with the same compressor.</p> </abstract>ARTICLE2021-04-30T00:00:00.000+00:00Selected Risks of the Decompression Process. Part I: Selected Inherent Residual Risks in the Decompression Processhttps://sciendo.com/article/10.2478/phr-2020-0006<abstract> <title style='display:none'>Abstract</title> <p>A safe transition from a higher-pressure atmosphere to a lower-pressure atmosphere is achieved by means of a planned decompression process, usually through changes in pressure and/or the composition of the breathing mix as a function of time. However, the decompression process is influenced by a greater number of inherent1 factors than merely changes in pressure and composition of the breathing mixture, the values of which should be maintained within certain ranges. However, there are instances where control over them cannot be maintained, leaving elements of residual risk2 to the decompression process. The safety of decompression should be assessed, inter alia, by analysing this risk for each implementation of the decompression process.</p> </abstract>ARTICLE2021-04-30T00:00:00.000+00:00Epidemiology of Basal Cell Carcinoma – Observations of One Departmenthttps://sciendo.com/article/10.2478/phr-2020-0011<abstract> <title style='display:none'>Abstract</title> <p><bold>Introduction.</bold> Basal cell carcinoma is the most common malignant skin cancer. It is one of the so-called nonmelanoma skin cancers, the incidence of which has increased rapidly worldwide in recent years. Unfortunately, the National Cancer Registry in Poland does not classify basal cell skin cancer separately. Therefore, the precise data on the incidence in the population remain unknown.</p> <p><bold>Work objective.</bold> Retrospective analysis of the incidence of basal cell carcinoma in NZOZ Med-Laser in Lublin in the years 2005 – 2015 depending on gender, age group, place of residence (urban-rural) and clinical form of the disease.</p> <p><bold>Material and methodology.</bold> The data of NZOZ Med-Laser from the years 2005 - 2015 were used in the study. The data concern all patients with histopathologically diagnosed basal cell carcinoma, who during the period covered by the study were consulted either as outpatients or hospitalised in an institution providing dermatological services under contract with the National Health Fund (NFZ). Patients were divided into several groups depending on gender, age and place of residence. All groups were compared quantitatively and the results are shown in the figures below.</p> <p><bold>Results.</bold> The data collected indicate that between 2005 and 2015 a total of 922 patients with basal cell carcinoma received dermatological treatment. Over the years, there has been a clear increase in the number of patients with basal cell carcinoma. The disease occurred mainly in people over 59 years of age, with the majority of women living in cities. The most common locations of the cancer are nose, cheeks, forehead and temporal area. Histopathologically, solidum, superficiale, exulceratum and pseudoadenoides were the most frequently diagnosed forms.</p> <p><bold>Conclusions.</bold> Basal cell carcinoma of the skin is frequent in our society. Its incidence has been increasing in recent years. Therefore, action should be taken to create consistent international registries to gather reliable epidemiological data that would show the scale of the problem, which we are dealing with almost all over the world.</p> </abstract>ARTICLE2021-04-30T00:00:00.000+00:00Cerebral Gas Embolism in the Course of Mildly Symptomatic Pulmonary Barotrauma in a Scuba Diverhttps://sciendo.com/article/10.2478/phr-2020-0008<abstract> <title style='display:none'>Abstract</title> <p>The paper presents a case of pulmonary barotrauma in a scuba diver. Swallowing water and respiratory arrest during the ascent caused the trauma. Symptoms from the respiratory system (including the Behnke’s symptom) appeared several minutes after the completion of the dive and were not severe. However, symptoms from the peripheral nervous system, which appeared later, increased rapidly until the seizure episode and loss of consciousness. Hyperbaric treatment was applied in a decompression chamber on board the ship from which the dive was conducted. The treatment resulted in complete remission of symptoms without any consequences.</p> </abstract>ARTICLE2021-04-30T00:00:00.000+00:00Pulmonary Barotrauma During Hypoxia in a Diver While Underwaterhttps://sciendo.com/article/10.2478/phr-2020-0009<abstract> <title style='display:none'>Abstract</title> <p>The article describes a diver performing a dive at small depths in a dry suit, breathing from a single-stage apparatus placed on his back. As a result of training deficiencies, the diver began breathing from inside the suit, which led to hypoxia and subsequent uncontrolled ascent. Upon returning to the surface, the diver developed neurological symptoms based on which a diagnosis of pulmonary barotrauma was made. The diver was successfully treated with therapeutic recompression-decompression.</p> </abstract>ARTICLE2021-04-30T00:00:00.000+00:00Functional Movement Screening as a Predictor of Injury in Highly Trained Female’s Martial Arts Athleteshttps://sciendo.com/article/10.2478/phr-2020-0012<abstract> <title style='display:none'>Abstract</title> <p><bold>Objective.</bold> This research examines the emerging role of FMS™ in the context of predicting lower extremity injury in females University athletes. The secondary purpose of this study is to investigate the differences between FMS performance comparisons between three martial arts sports to establish baseline comparisons.</p> <p><bold>Method.</bold> Forty-seven university female athletes were recruited for this study, The data collected was separated into three groups based on their sports discipline (judo N=17 age: 19±4, wrestling N=15 age: 18±5, karate N=15 age: 19±3), Independent t-tests were performed on each group with significance being set at P&lt;0.05 to determine difference in FMS™ scores between injured and non injured athletes during the successive competitive seasons. One-way analyses of variances were used to determine if there was a significant difference between sports, ‘body parts injured’ groups, and ‘mechanisms of injury’ groups.</p> <p><bold>Results.</bold> One-way analysis of variance revealed no statistically significant difference between the two (ankle, knee) injury groups, and non-injury group (F2,54= 2.34; p=0.106). There was no statistical difference between the pre-season FMS™ scores of the injured and non-injured groups (t47 = -1.68; P=.100; d=0.52; 95%CI: -0.11, 1.15). Finally, strong evidence of FMS score was found when comparing the three sports with one-way ANOVAs (F=5.83, df= 2, 54, p=0.005).</p> <p><bold>Conclusion.</bold> One of the more significant findings to emerge from this study is that FMS™ has emerged as a powerful tool for identifying lower extremity injury in female athletes. Further investigation and experimentation into FMS™ are strongly recommended before implementing them into a pre-participation physical examination (PPE) for combat sports. What is now needed is a cross-national study involving other sports.</p> </abstract>ARTICLE2021-04-30T00:00:00.000+00:00en-us-1
