Blood Pressure Stability and Plasma Aldosterone Reduction: The Effects of a Sodium and Bicarbonate-Rich Water - A Randomized Controlled Intervention Study.

Objective: Hypertension is a recognized risk factor for cardiovascular disease (CVD), and dietary sodium intake has been linked to its development. However, mineral water high in bicarbonate and sodium does not appear to have adverse effects on blood pressure.This study examines the effects of consuming a mineral water high in bicarbonate and sodium (HBS) compared to a low bicarbonate and sodium (LBS) mineral water on blood pressure and related factors.Methods: A randomized controlled intervention was conducted with 94 healthy participants, consuming 1,500 - 2,000 mL daily of either mineral water high in bicarbonate and sodium (HBS water, n = 49) or low in bicarbonate and sodium (LBS water, n = 45). Blood pressure, anthropometrics, and urinary calcium and sodium excretion were assessed at baseline and after 28 days. 3-day food protocols were assessed to evaluate possible dietary changes.Results: Blood pressure changes did not differ between the groups. Both normotensive and hypertensive subjects showed similar changes in systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) in response to the different test waters. Serum aldosterone decreased significantly in both groups, with a greater reduction in the HBS group. Urinary calcium excretion significantly decreased (p = 0.002) and sodium excretion increased in the HBS group. Multiple linear regression analyses indicated no association between urinary sodium excretion and systolic blood pressure increase in the HBS group (B = 0.046, p = 0.170). Changes in urinary sodium excretion did not correlate with changes in serum aldosterone in the same group (r=-0.146, p = 0.350).Conclusions: The study revealed no significant differences in blood pressure changes between individuals consuming HBS water and LBS water. Notably, the additional sodium intake from the test water was effectively excreted.Trial registration: This trial was registered in the German Clinical Trials Register (DRKS00025341, https://drks.de/search/en).

What is the context? High blood pressure is a risk factor for heart diseases, one of the leading causes of illness and death worldwide. Too much sodium in the diet has been linked to the development of high blood pressure. However, some high-sodium mineral waters appear to have a different effect on blood pressure. Researchers have demonstrated that mineral waters high in both sodium and bicarbonate may not have harmful effects on blood pressure.What is the study about? In this study, 94 healthy participants between the ages 30 to 65 were divided into two groups. One group drank high-bicarbonate, high-sodium mineral water, and the other group drank low-bicarbonate, low-sodium mineral water for four weeks. Blood pressure was measured before and at the end of the study. The participants were asked not to change their usual diet and physical activity during the study.What are the results? Blood pressure did not change differently between the two groups. Consumption of high-sodium, high-bicarbonate mineral water increased sodium intake, but sodium was effectively excreted in the urine. Moreover, aldosterone, a blood pressure regulating hormone, decreased with mineral water consumption. Its reduction is good for maintaining stable blood pressure.

Balneotherapy using thermal mineral water baths and dermatological diseases: a systematic review.

Balneotherapy includes practices and methods using medically and legally recognized mineral-medicinal waters, muds and natural gases from natural springs for therapeutic purposes. One of the most widely used method in balneotherapy is bathing with thermal mineral water. In the course of the years, scientific community has produced an increasing number of evidences that this practice is an effective method for treating signs and symptoms of several pathologies such as rheumatic, cardiovascular and dermatological diseases. This systematic review is aimed at evaluating the effect of balneotherapy with thermal water baths as a treatment to manage signs and symptoms of patients affected by all types of dermatological diseases. The systematic review was conducted according to the PRISMA Statement, and its protocol was registered on PROSPERO platform (CRD42022295913). The research was performed on the databases Pubmed, Scopus, Web of Science and Cochrane. We included clinical trials evaluating the effects of balneotherapy using thermal mineral water baths for managing dermatological diseases in humans, published in English and Italian language. Eight studies were included, seven of them enrolled adults affected by psoriasis and one studied atopic dermatitis patients. The common result of all the articles included was a clear improvement of signs and symptoms of psoriasis and eczematous diseases after use of thermal mineral water baths. These effects seem to be strictly related to physical and chemical properties of thermal water used for balneotherapy. However, studies in this field are still limited to support robust evidence of the effectiveness of balneotherapy using thermal mineral water baths and often their quality is low. Thus, new clinical studies need to be carried out, using more correct methods for conducting the studies and for processing statistical data.

Biophysical effects of a natural peloid on normal skin.

A protocol study was designed to examine cutaneous behavior after continuous application of a peloid in the dry mineral residue of Lanjarón-Capuchina natural mineral water. This study aims to analyze the biomechanical behavior of normal skin using various non-invasive bioengineering techniques after the application of this peloid. We determine the effects of its application for 3 months on 38 healthy volunteers (41.4 ± 5.9 years, range 32-58) without a previous history of skin diseases by courtmetry, sebumetry, pH-metry, reviscometry, and tewametry. It was shown that the production of cutaneous sebum is significantly reduced by 6%, trans epidermal skin loss (TEWL) by 21%, skin fatigue by 30%, elasticity increased by 19%, firmness by 5%, and a skin redensification by 6% was obtained under these experimental conditions. Disparate and non-significant results were obtained concerning pH and viscoelasticity. Continuous skin care with the Lanjarón-Capuchina natural peloid modifies skin behavior, normalizing sebaceous secretion, favoring the biomechanical properties of the skin and the skin barrier function without modifying skin homeostasis.

Evaluating boron levels in Turkish mineral waters: a comparative study of three analytical techniques.

Turkey is abundant in natural mineral water sources, thanks to its location on the Alpine-Himalayan belt. Natural mineral water is drinking water characterized by its natural mineral, trace elements, and carbon dioxide content. Because of quite insufficient data, the boron content in bottled natural mineral waters in Turkey was analyzed by three different methods and compared: inductively coupled plasma mass spectrometry technique, carminic acid, and azomethine-H methods, in this study. The boron levels in mineral waters ranged from a minimum of 0.05 mg/L to a maximum of 8.61 mg/L. It was also safe by the upper limit level estimated by the World Health Organisation. As boron plays a beneficial role in human physiology, consuming natural mineral water may offer a positive contribution to public health by supporting boron intake in our country. The other outcome of our research was that the spectrophotometric carminic acid method can yield results similar to those obtained using the inductively coupled plasma mass spectrometry technique since the boron level of Turkish mineral water was within the limits level of the carminic acid method. However, the result of the azomethine-H method was found not to be suitable. Cross-sensitivity with other elements in mineral water might have caused this.

[Development of adaptive reactions when applying drinking mineral water and electromagnetic radiation against the background of a high-calorie diet on the model of experimental metabolic syndrome]. / Razvitie adaptivnykh reaktsii pri primenenii pit'evoi mineral'noi vody i elektromagnitnogo izlucheniya na fone deistviya vysokokaloriinoi diety na modeli eksperimental'nogo metabolicheskogo sindroma.

OBJECTIVE: To identify features of development of adaptive protective reactions when applying drinking sulfate mineral water (MW) and low-intensity electromagnetic radiation of extremely high frequency (EMR EHF) against the background of a high-calorie diet and after its elimination at an early stage of development of experimental metabolic syndrome. MATERIAL AND METHODS: Experiments were conducted on 40 non-linear male rats with 200-220 g. weight. The model of metabolic syndrome was reproduced for 60 days. All animals were divided into 5 groups: 2 study groups, 2 control groups and 1 intact one. Rats of the 1st study group were given sulfate MW in combination with EMR EHF against the background of a high-calorie diet, controlled by rats receiving only a high-energy diet. Rats of the 2nd study group also received sulfate MW in combination with EMR EHF but when the metabolic syndrome simulation was finished and the high-calorie diet was eliminated, control was done by rats that were given standard food after eliminating the high-energy diet. Liver, testes and blood were objects of the study. Light-optical, morphometric methods of examination and electron microscopy were used. RESULTS AND DISCUSSION: The use of sulfate MW in combination with EMR EHF against the background of the high-calorie diet was the most cause of increased activity of the antioxidant system and the plastic processes were weaker; the activation of natural adaptive reactions was noted after the elimination of the diet that in combination with actions of MW and EMR EHF led to the further intensification of protein synthesis (RNA, DNA, total protein), intensification of cellular and intracellular regeneration processes. The identified adaptive shifts during the action of the studied factors were caused by their antioxidant, membrane stabilizing and detoxifying actions. CONCLUSION: The results of the study can be used to develop the problem of regulating adaptive reactions with the application of therapeutic physical factors and to create new highly effective methods of preventing and treating metabolic syndrome.

Metasilicate-based alkaline mineral water confers diarrhea resistance in maternally separated piglets via the microbiota-gut interaction.

Stress or stress-induced intestinal disturbances, especially diarrhea, are the main triggers for inflammatory bowel disease and irritable bowel syndrome. Diarrhea and intestinal inflammatory disease afflict patients around the world, and it has become a huge burden on the global health care system. Drinking sodium metasilicate-based alkaline mineral water (SM-based AMW) exerts a potential therapeutic effect in gastrointestinal disorders, including gut inflammation, and diarrhea, but the supportive evidence on animal studies and mechanism involved remain unreported. The maternally separated (MS) piglet (Newly weaned piglet) is an excellent model to investigate the treatment of diarrhea in infant. This study aims to determine whether drinking SM-based AMW confers diarrhea resistance in maternally separated (MS) piglets under weaning stress and what the underlying mechanisms are involved. 240 newly weaned piglets were randomly divided into the Control group and the sodium metasilicate pentahydrate (SMP) group. A decreased diarrhea incidence was observed in SMP treatment piglets. The intestine injury and activated stress hormones (COR and ACTH) induced by weaning was alleviated by SM-based AMW. This may be related to the improvement of intestinal microflora structure and function by SMP, especially the increase of s_copri abundance. Meanwhile, SMP maintained the integrity of the duodenal mucus barrier in MS piglets. Importantly, by targeting NF-κB inhibition via the microbiota-gut interaction, SM-based AMW alleviated intestinal inflammation, maintained fluid homeostasis by modulating aquaporins and fluid transporter expression, and enhanced barrier integrity by suppressing MLCK/p-MLC signaling. Therefore, drinking metasilicate-based alkaline mineral water confers diarrhea resistance in MS piglets via the microbiota-gut interaction.

Transformation of Iminodi(methylene phosphonate) on Manganese Dioxides - Passivation of the Mineral Surface by (Formed) Mn2.

Aminopolyphosphonates (APPs) are strong chelating agents with growing use in industrial and household applications. In this study, we investigated the oxidation of the bisphosphonate iminodi(methylene phosphonate) (IDMP) - a major transformation product (TP) of numerous commercially used APPs and a potential precursor for aminomethylphosphonate (AMPA) - on manganese dioxide (MnO2). Transformation batch experiments at pH 6 revealed AMPA and phosphate as main TPs, with a phosphorus mass balance of 80 to 92% throughout all experiments. Our results suggest initial cleavage of the C-P bond and formation of the stable intermediate N-formyl-AMPA. Next, C-N bond cleavage leads to the formation of AMPA, which exhibits lower reactivity than IDMP. Reaction rates together with IDMP and Mn2+ sorption data indicate formation of IDMP-Mn2+ surface bridging complexes with progressing MnO2 reduction, leading to the passivation of the mineral surface regarding IDMP oxidation. Compound-specific stable carbon isotope analysis of IDMP in both sorbed and aqueous fractions further supported this hypothesis. Depending on the extent of Mn2+ surface concentration, the isotope data indicated either sorption of IDMP to the mineral surface or electron transfer from IDMP to MnIV to be the rate-limiting step of the overall reaction. Our study sheds further light on the complex surface processes during MnO2 redox reactions and reveals abiotic oxidative transformation of APPs by MnO2 as a potential process contributing to widespread elevated AMPA concentrations in the environment.

Balneotherapy for osteoarthritis: a systematic review.

This systematic review is aimed to evaluate the effects of balneotherapy with thermal mineral water for managing the symptoms and signs of osteoarthritis located at any anatomical site. The systematic review was conducted according to the PRISMA Statement. The following databases were consulted: PubMed, Scopus, Web of Science, Cochrane Library, DOAJ and PEDro. We included clinical trials evaluating the effects of balneotherapy as a treatment for patients with osteoarthritis, published in English and Italian language, led on human subjects. The protocol was registered in PROSPERO. Overall, 17 studies have been included in the review. All of these studies were performed on adults or elderly patients suffering from osteoarthritis localized to knees, hips, hands or lumbar spine. The treatment assessed was always the balneotherapy with thermal mineral water. The outcomes evaluated were pain, palpation/pressure sensibility, articular tenderness, functional ability, quality of life, mobility, deambulation, ability to climb stairs, medical objective and patients' subjective evaluation, superoxide dismutase enzyme activity, serum levels of interleukin-2 receptors. The results of all the included studies agree and demonstrated an improvement of all the symptoms and signs investigated. In particular, pain and quality of life were the main symptoms evaluated and both improved after the treatment with thermal water in all the studies included in the review. These effects can be attributed to physical and chemical-physical properties of thermal mineral water used. However, the quality of many studies resulted not so high due and, consequently, it is necessary to perform new clinical trial in this field using more correct methods for conducting the study and for processing statistical data.

Unveiling the Therapeutic Potential and Healthcare Applications of Marine Therapy: A Systematic Review with Meta-Analysis and Meta-Regression.

This study was conducted to estimate the effectiveness of marine-derived resources for treating specific diseases, as well as identify the most effective methods for applying such resources in therapeutic applications. Bibliographic databases (PubMed, Embase, and Cochrane) were searched from their inception until May 2023 using Medical Subject Headings terms and text keywords related to seawater, mineral water, or ocean therapy. Fifteen eligible studies were included, involving 1325 participants aged 42.7-63.0 years. In the subgroup analysis based on treatment type, the mean difference was -1.581 (95% CI: -1.889, -1.274) for seawater with sun exposure and -1.210 (95% CI: -1.417, -1.002) for seawater with sun exposure, mud pack application, and sulfur pool therapy. The pooled standardized mean difference was calculated for different outcomes; the results were -1.110 (95% CI: -3.028, 0.806) for osteoarthritis severity, -0.795 (95% CI: -0.982, -0.607) for arthritis pain, -1.623 (95% CI: -2.036, -1.209) for fibromyalgia pain, and -1.498 (95% CI: -1.888, -1.108) for quality of life. Marine therapy is, therefore, promising for treating chronic skin issues, easing musculoskeletal discomfort, and enhancing the quality of life among patients with musculoskeletal pain.

The effects of immersion in 42℃ radon, natrium, calcium, bicarbonate content thermal-mineral water on chronic low back pain. Controlled, follow-up study.

In our minimized follow-up trial with 137 participants with chronic low back pain, one group of participants received regular outpatient care, and the other group received balneotherapy by immersion in 42℃ thermal-mineral water in addition to regular outpatient care on 15 occasions for 3 weeks. Pain on movement and at rest on the 0-100 mm visual analogue scale (VAS), Oswestry index, the number of participants evaluating the symptoms clinically acceptable (Patient Acceptable Symptom State, PASS) and the EuroQol-5D-5L (EQ-5D-5L) quality of life questionnaire were assessed at basal time (at week 0) and after balneotherapy (at weeks 3 and 12). The VAS pain scores, the Oswestry index, the EQ-5D-5L index and the EQ-VAS significantly improved in the balneotherapy group after treatment at week 3 (p < 0.001) and week 12 (p < 0.001) compared to baseline, with a significant between group difference at week 3 (p < 0.001) and week 12 (p < 0.001). The pain VAS score on movement was 66.82 ± 11.48, 26.69 ± 21.49, and 20.09 ± 23.29 in the balneotherapy group, and 63.67 ± 14.77, 67.35 ± 15.44, and 70.23 ± 18.26 in the control group at the consecutive visits. The PASS increased in both groups at week 3 and week 12 compared to the baseline, with a significant between-group difference at week 3 and week 12 for the balneotherapy group. Our results suggest the therapeutic efficacy of immersion in 42℃ thermal mineral water on chronic low back pain.ClinicalTrials.gov Identifier: NCT05342051.

Exploring the Effect of Deep-Sea Water on the Therapeutic Potential of the Anti-Inflammatory Response in an Indomethacin-Induced Gastric Ulcer Rat Model.

Gastric ulcers are often exacerbated by factors such as nonsteroidal anti-inflammatory drugs (NSAIDs) and inflammation, and they have a substantial impact on a significant portion of the population. Notably, indomethacin is recognized as a prominent contributor to ulcers. This study investigated this potential method, with normalization to the anti-inflammatory and antiulcer properties of deep-sea water (DSW)-derived mineral water, using an indomethacin-induced gastric ulcer model in rats. The study involved four groups (n = 6 rats/group): normal control group (CON), indomethacin-only group (IND), indomethacin with trace mineral water group (TM), and indomethacin with high magnesium low sodium water group (HMLS). For three weeks, the CON and IND groups consumed tap water, while the TM and HMLS groups had access to mineral water. Gastric ulcers were induced on the final day using indomethacin, for all groups except the CON group. The results demonstrated that HMLS intake significantly improved gastric mucosal damage, preserved mucin stability, and increased gastric thickness, indicating its potential to prevent and alleviate indomethacin-induced gastric ulcers. Furthermore, HMLS consumption led to the upregulation of key genes associated with inflammation and a reduction in inflammatory cytokines. These findings suggest that DSW-derived mineral water, and particularly its high Mg2+ content, may offer promising health benefits including anti-inflammatory and anti-ulcer properties.

The effect of transportation vibration on the microbiological status of bottled mineral water.

BACKGROUND: Microbiological status and stability are important in mineral waters because of increased global demand. An increase in distribution and supply chains has led to prolonged periods of transportation, causing microbiological changes. Therefore, this study examines the effect of vibration on mineral water quality. Freshly bottled and previously sterilized mineral waters inoculated with microbes isolated from freshly bottled water were tested. The water samples were exposed to random vibration using ASTM (D4169) truck level I, II and III standard vibration protocol for truck transportation at 4 × 1 h at 22 ± 1 °C. After agitation their microbiological status was determined. RESULTS: Under the influence of low-intensity mechanical impact, the growth rate of autochthonous species in the freshly bottled natural mineral water tripled (µcontrol  = 0.036 h-1 , µvibrated  = 0.093 h-1 ) and that of allochthonous species doubled (µcontrol  = 0.035 h-1 , µvibrated  = 0.069 h-1 ). The latter was also observed in the case of high-intensity vibration (µcontrol  = 0.102 h-1 , µvibrated  = 0.200 h-1 ). The effect of the medium intensity of the standard was manifested in the delay in microbial growth. CONCLUSION: The impact of transportation vibrations on microbiological status changes in mineral water could be observed when subjected to vibration. The native and allochthonous species of mineral water respond differently to changes in intensity. © 2022 The Authors.

Potentially toxic element contamination and health risk assessment in bottled mineral waters consumed in Turkey.

This study aimed to evaluate the human health risk posed by potentially toxic elements (PTEs) in 59 bottled mineral water (BMW) samples of 25 different brands marketed in Turkey. The concentrations of Ag, Al, As, Cd, Cr, Co, Cu, Fe, Mn, Ni, and Pb in the BMW samples were analyzed using an ICP-OES and compared with maximum allowable concentrations (MACs). A higher concentration of As than MAC was detected in five BMW samples. The concentrations of Cd, Pb, Cr, Ni, and Al in the majority of BMW samples are higher than the MACs. The human health risk was evaluated for adults estimating non-carcinogenic risk index (HI), incremental lifetime cancer risk (ILCR) and total cancer risk (TCR). All HI values estimated for PTEs in BMW samples are less than one, except for one sample. ILCR values for Cd in approximately half of the BMW samples are above the upper limit.

Measurement of radium and radon gas in bottled mineral waters.

In this study, the radon gas and radium concentration in the bottled mineral water samples was measured. A total of sixty samples were collected from bottled mineral water sold in the markets in Kahramanmaras. DURRIDGE Rad7 electronic radon detector was used for measurements. Radon and radium activity amounts range from 33.50 ± 1.30 mBq/L to 51.70 ± 2.20 mBq/L, and 2.92 ± 0.15 mBq/L to 4.51 ± 0.26 mBq/L, respectively. Average radon and radium active amounts are 41.67 ± 1.54 mBq/L and 3.63 ± 0.18 mBq/L, respectively. Total annual effective dose values were calculated for these mineral waters according to three different scenarios. In the first of these, it was assumed that natural mineral water was consumed annually instead of 730 L of drinking water (S1). In the second case, 150 L which was the annual average amount of natural mineral water consumed in European Union member countries was used for the annual average amount of natural mineral water consumed by adults (S2). Finally, the annual average amount of natural mineral water consumed in Turkey, 14 L, was used for adults (S3). For scenarios (S1, S2, S3), the total (ingestion + inhalation) annual average dose values ranged from 6.83E-04 mSv/y to 1.05E-03 mSv/y, 1.40E-04 mSv/y to 2.17E-04, and 1.32E-05 mSv/y to 2.03E-05 mSv/y, their average values were 8.49E-04 mSv/y, 1.75E-04 mSv/y, and 1.64E-05 mSv/y, respectively. The total effective dose values calculated within the scope of the current study were below the limit value announced by WHO.

[Validation Study on Developed Methods for Anions and Bromic Acid in Various Mineral Waters by Ion Chromatography].

Five kinds of anions namely fluoride, chlorate, chlorite, nitrate and nitrite ions, and bromic acid were determined in various mineral waters (MWs), and the methods were validated. MWs are varying in the degree of hardness and contents of carbonate. When the five anions were measured based on the official method of tap water, the peak shape of fluoride ion in MWs with high degree of hardness was different from the standard solution, making it difficult to determine. The same phenomenon was also observed when bromic acid was measured. In order to achieve accurate determination, five-fold dilution with ultrapure water was carried out on the samples. With the additional step, the abnormal peak of both analytes was improved, and no difference in the retention times between standard and sample solutions was observed. The validation tests were performed using the developed methods with the additional diluting step, and the results of all target substances met the criteria of the guideline on analytical method validation for MW in Japan. Our results suggested that the methods we developed could be useful for the accurate determination of the anions and bromic acid in various MWs on the market.

Effect of Calcium-Sulphate-Bicarbonate Water in a Murine Model of Non-Alcoholic Fatty Liver Disease: A Histopathology Study.

The progression of nonalcoholic fatty liver disease (NAFLD) is associated with alterations of the gut-liver axis. The activation of toll-like receptor 4 (TLR4) pathways by endotoxins, such as lipopolysaccharide (LPS), contributes to liver injury. The aim of the present study was to evaluate the possible beneficial effects of a calcium-sulphate-bicarbonate natural mineral water on the gut-liver axis by evaluating liver and terminal ileum histopathology in a murine model of NAFLD. NAFLD was induced in mice by administrating a methionine-choline-deficient (MCD) diet. The following experimental groups were evaluated: controls (N = 10); MCD+Tap water (MCD; N = 10); MCD+Calcium-sulphate-bicarbonate water (MCD/Wcsb; N = 10). Mice were euthanised after 4 and 8 weeks. Liver and terminal ileum samples were collected. Samples were studied by histomorphology, immunohistochemistry, and immunofluorescence. In mice subjected to the MCD diet, treatment with mineral water improved inflammation and fibrosis, and was associated with a reduced number of activated hepatic stellate cells when compared to MCD mice not treated with mineral water. Moreover, MCD/Wcsb mice showed lower liver LPS localization and less activation of TLR4 pathways compared to the MCD. Finally, Wcsb treatment was associated with improved histopathology and higher occludin positivity in intestinal mucosa. In conclusion, calcium-sulphate-bicarbonate water may exert modulatory activity on the gut-liver axis in MCD mice, suggesting potential beneficial effects on NAFLD.

Isolated fetal echogenic bowel and iron-rich mineral water supplement: a case series and review of the literature.

Natural iron-rich mineral water (IRMW) is a supplement with a higher iron bioavailability than oral iron supplement tablets. Five (4%) of 116 women who consumed IRMW starting from 16 weeks of gestation were diagnosed as having isolated foetal echogenic bowel at a single community maternity clinic between 2012 and 2015. The workup of all the women was otherwise negative. Four women taking IRMW were re-checked after discontinuation of the supplement and had a normal-appearing foetal bowel. Our observations suggest that isolated echogenic bowel may be related to the consumption of IRMW, possibly due to the high absorption of iron, leading to the coating of the internal wall of the foetal bowel and subsequent appearance of an echogenic bowel. Although this finding appears free of harmful ramifications, its possible sonographic effects on the appearance of the foetal bowel should be considered in light of the increasing popularity of IRMW use.IMPACT STATEMENTWhat is already known on this subject? IRMW is a highly absorbed iron supplement. The differential diagnosis for foetal echogenic bowel is broad and requires thorough investigation. Iron is secreted through the maternal blood to the amniotic fluid, which is swallowed by the foetus, reaching its bowel.What do the results of this study add? IRMW consumption is a possible aetiology of an isolated foetal echogenic bowel in the second half of pregnancy, conveying no risk of foetal morbidity or mortality.What are the implications of these findings for clinical practice and/or further research? In light of the increasing popularity of IRMW, we believe that it is important to increase the level of awareness of the possible effects of its intake on the sonographic appearance of the foetal bowel.

Geochemistry and therapeutic properties of Caucasian mineral waters: a review.

The Caucasian mineral water (CMW) region is a unique area where mineral waters differ by their chemical composition and balneological properties. The presence of a wide range of mineral waters with various ions and gas components and different genesis and their therapeutic properties in the restricted area is explained by complicated geological and tectonic settings. The dominant type of mineral water in the CMW region is CO2-bearing water with H2SiO3 and H3BO3 as the specific components. According to ion composition, gas phases' content into groundwater, total dissolved solids, and balneological characteristics, we would distinguish 9 groups and 16 types of these mineral waters, with each water type being of particular therapeutic interest. The CMW region includes four spa cities with a different therapeutic profile: Zheleznovodsk, Kislovodsk, Pyatigorsk, and Essentuki. Spa treatment is based on the use of different types of mineral waters, therapeutic muds within the region's diverse landscapes, and climatic conditions. Mineral waters are utilized in the form of baths, swimming pools, showers, various irrigations, inhalation, as well as drinking therapy. Therapeutic mineral waters are used to treat gastrointestinal problems, metabolic and nervous system disorders, as well as various diseases of liver, kidney, urinary tract, circulatory system, respiratory organs, and skin.

Understanding the processes in a historically relevant thermal and mineral spring water by using mixing and inverse geochemical models.

The thermal mineral water of Peñón de los Baños spa (Mexico City) has been used for over 500 years starting in pre-Hispanic times and is famous for the treatment of various pathologies. It has a temperature of 45 °C, which is rich in HCO3-, and its main trace elements are B, Li and Fe, which confers healing effects. Concerns about the sustainability of this important spa have motivated this study to understand the thermal system, possible hydraulic and hydrochemical changes over time and its implications. Stable water isotope data indicate that the thermal water sources originate from local precipitation at Sierra de las Cruces with a recharge elevation of approximately 2770 m above sea level. The recharged water percolates through volcanic and carbonate rock formations and ascends via fault structure conduits, where it eventually is extracted 25 km downstream in Peñon de los Baños. During the gravity-driven deep circulation of up to 4.9 km, the groundwater is heated up to 136-160 °C. A comparison of past and current water levels and water chemical analyses indicates a water table drop and few variations in the chemical composition, confirming the presence of anthropic impact on water quality. Due to the heavy groundwater extractions in Mexico City, the spring water flow has ceased, and water must be pumped now from a 203-m deep well. In addition, the concentration of bicarbonate, sodium and chloride has been reduced by half since the onset of groundwater development. The therapeutic effects of this thermal mineral water are at risk due to the alteration of the chemical signature. However, new and different therapeutical uses may prevent a future deterioration or closure of this historically important thermal spa. It is crucial to establish a monitoring program of the thermal mineral water and reducing or minimizing nearby urban extractions which tap the regional flow component to preserve the properties of the thermal water.
