New study suggests kidney function is associated with tooth loss in postmenopausal women

Low tooth count is linked with systemic diseases such as diabetes, thyroid disease, and osteoporosis, plus an increased risk of stroke

2024-06-12

(Press-News.org) CLEVELAND, Ohio (June 12, 2024)—Kidneys play a critical role in overall health by removing waste products from the blood. When they fail to sufficiently filter out foreign elements, several serious, lifethreatening, medical conditions can result. A new study suggests that chronic kidney disease may also be linked with tooth loss. Results of the survey are published online today in Menopause, the journal of The Menopause Society.

A woman’s glomerular filtration rate shows how well her kidneys are functioning. Kidney function decreases with time after menopause and is associated with declining reproductive hormone levels. These hormone changes during menopause also often lead to abdominal obesity, which is an independent risk factor for the development of chronic kidney disease and also linked with a higher risk of tooth loss.

The consequences of kidney disease are numerous, including an increased probability of experiencing problems with bone and cardiovascular health. Tooth loss, which reflects oral health status, is also associated with systemic diseases, such as diabetes, thyroid disease, and osteoporosis, and is independently associated with an increased risk of stroke. Excessive tooth loss can also impair chewing and speech.

Previous studies have identified an association between kidney function and tooth count. This newest study involving nearly 65,000 participants, however, is the first known to evaluate the association between chronic kidney disease and tooth loss in postmenopausal women across the ages. It concluded that the glomerular filtration rate, a measure of kidney function, is significantly associated with having at least 20 (of a total of 28) adult teeth, suggesting that chronic kidney disease and tooth loss are significantly associated, especially in postmenopausal women aged 66 to 79 years.

These findings suggest that preventing and managing mineral and bone metabolism disorders in postmenopausal women with chronic kidney disease are crucial to prevent tooth loss. It is also important to address kidney disease progression, as the consequences affect multiple body systems beyond just oral health.

Survey results are published in the article “Chronic kidney disease in postmenopausal women is associated with tooth loss.”

“This study highlights the known link between chronic kidney disease and bone metabolism. Increased attention to oral and bone health is warranted in postmenopausal women with chronic kidney disease, in addition to meticulous efforts aimed at preserving kidney function. Conversely, oral health is a window to overall health, and good oral hygiene is important for women of all ages,” says Dr. Stephanie Faubion, medical director for The Menopause Society.

Breakthrough MEMS Huygens clock improves timekeeping precision and stability

2024-06-12

In a significant development for the miniaturization of electronic devices, a new study published in Engineering has reported the creation of a Microelectromechanical Systems (MEMS) clock that offers improved precision and stability. The clock, which utilizes the synchronization principle discovered by the Christiaan Huygens, consists of two synchronized MEMS oscillators and a frequency compensation system. The research details how the MEMS Huygens clock enhances short-time stability, with the Allan deviation – a measure of the clock’s accuracy over time – improving by a factor of 3.73 from 19.3 ppb to 5.17 ppb at 1 second. The clock's long-term ...

HKUMed’s world-first ‘Liver-in-Cube’ wins a gold medal at International Exhibition of Inventions of Geneva, advancing precise cancer treatment

2024-06-12

Background Liver cancer is the sixth most common cancer and third leading cause of cancer death globally. According to Hong Kong Cancer Registry data, there are approximately 1,800 new cases of liver cancer each year, with over 1,500 deaths, over 80% of which are advanced cases at first diagnosis. Patients with advanced liver cancer who are not suitable for surgical operations have limited treatment options. Traditional chemotherapy, targeted therapy and immunotherapy for treating advanced liver cancer often have a low response rate and severe side effects, thereby limiting their efficacy and hindering the patient’s quality ...

Nationwide zonation and durability assessment of China’s plateau infrastructure under freeze–thaw cycles

2024-06-12

In a bid to tackle the enduring problem of infrastructure durability in the face of relentless freeze–thaw (F–T) cycles, a team of researchers has published a new study in Engineering. The study focuses on the Chinese Plateau region, where the harsh effects of F–T cycles on concrete structures have led to concerns regarding their aging and subsequent performance deterioration. The authors of the study emphasize that the existing national standards for designing frost-resistant concrete structures are insufficient, as they rely primarily on the coldest monthly average temperature without accounting for the intricate spatiotemporal variations, amplitude, and ...

Innovative CMUT-based resonant biosensor offers enhanced DNA detection specificity

2024-06-12

In the latest study, researchers have successfully demonstrated a novel biosensor capable of detecting single-stranded DNA oligonucleotides with high specificity without needing external labels. This advancement paves the way for more accessible and efficient point-of-care diagnostics, as reported in a recent study published in Engineering. The biosensor in question is based on capacitive micromachined ultrasonic transducers (CMUTs), which have shown promise for developing miniaturized, high-performance biosensing platforms. However, previous ...
